New testing method can diagnose COVID-19 in just 30 minutes, study finds

OCT 06, 2020 SEOUL: Scientists have developed a new method that allows anyone to easily and quickly detect COVID-19 in just 30 minutes, and is as accurate as the current PCR diagnostic test. The SENSR technology developed by researchers at Pohang University of Science & Technology (POSTECH) in South Korea diagnosis COVID-19 based on the RNA sequence of the virus, reducing the stress on one single testing location and avoiding contact with infected patients as much as possible. RNA is a nucleic acid that mediates genetic information or is involved in controlling the expression of genes. The biggest benefit is that a diagnostic kit can be developed within a week even if a new infectious disease appears other than COVID-19, according to the research published in the journal Nature Biomedical Engineering. The researchers noted that PCR molecular test currently used for COVID-19 diagnosis has very high accuracy but entails a complex preparation process to extract or refine the virus. The test is not suitable for use in small farming or fishing villages, or airport or drive-thru screening clinics as it requires expensive equipment as well as skilled experts, they said. The researchers designed the test kit to produce nucleic acid binding reaction to show fluorescence only when COVID-19 RNA is present. The virus can be detected immediately without any preparation process with high sensitivity in a short time. And it is as accurate as the current PCR diagnostic method. Using the new technology, they found the SARS-CoV-2 virus RNA, the cause of COVID-19, from an actual patient sample in about 30 minutes. In addition, five pathogenic viruses and bacterial RNAs were detected which proved the kit's usability in detecting pathogens other than COVID-19, according to the researchers. Another great advantage of the SENSR technology is the ease of creating the diagnostic device that can be developed into a simple portable and easy-to-use form, the researchers said. The method not only allows onsite diagnosis before going to the screening clinic or being hospitalised, but also allows for a more proactive response to COVID-19 by supplementing the current centralized diagnostic system. "This method is a fast and simple diagnostic technology which can accurately analyse the RNA without having to treat a patient's sample," said POSTECH Professor Jeong Wook Lee. "We can better prepare for future epidemics as we can design and produce a diagnostic kit for new infectious diseases within a week," Lee said. Copyright © Jammu Links News, Source: Jammu Links News

Blood serum from animals can slash Covid severity: ICMR

a

The Indian Council of Medical Research (ICMR) in collaboration with a Hyderabad-based pharmaceuticals and biologics company, has introduced a well-established treatment modality to control the severity of COVID-19 disease, the apex research institute informed on Thursday.

"The ICMR along with Biological E. Limited have developed "highly purified antisera (raised in animals) for prophylaxis and treatment of the viral disease," it said.

Antisera are blood serum derived from animals which contain antibodies against specific antigens. They are injected to treat or protect against specific diseases. After plasma therapy, it is the latest therapy to be used to treat and prevent the severity of COVID-19 disease among the patients.

While plasma therapy could not derive a satisfactory result in reducing mortality of the severe patients of COVID-19, the ICMR has high hopes riding on the antisera therapy. "Although, plasma recovered from patients experiencing COVID-19 could serve a similar purpose, the profile of antibodies, their efficacy and concentration keep varying from one patient to another and therefore make it an unreliable clinical tool for patient management," the ICMR stated.

However, the therapeutic use of antisera is not new to medical science. The ICMR said that it has been used to control many viral and bacterial infections. Besides, the World Health Organisation (WHO) has listed it as a life-saving medicine.

"Such measures have previously been used in medical science to control many viral and bacterial infections such as Rabies, Hepatitis B, Vaccinia virus, Tetanus, Botulism and Diphtheria," the ICMR stated.

While the use of convalescent plasma as a treatment modality for COVID-19 has received authorisation for off-label use in India, a study conducted by the ICMR suggested that its administration did not reduce mortality or progression to severe COVID-19 condition among the patients.

The study, published on September 8, was conducted in 39 tertiary care hospitals across the country.

A total of 464 participants were enrolled between April 22 and July 14 in the trial which was aimed to investigate its effectiveness for treatment of COVID-19.

However, the ICMR did not share particulars related to clinical testing and trials of the antisera therapy on humans. Source: https://southasiamonitor.org

Strong activation of anti-bacterial cells of immune system linked to severe COVID-19: Study

SEP 29, 2020 LONDON: A type of the immune system's T cells known to fight against bacterial infections is strongly activated in people with moderate to severe COVID-19, according to a study which provides a better understanding of how the body responds to the novel coronavirus infection. Researchers, including those from the Karolinska Institute in Sweden, noted that this component of the immune system called MAIT cells make up about one to five percent of T cells in the blood of healthy people, and are primarily important for controlling bacteria, but can also be recruited to fight some viral infections. They explained that T cells are a type of white blood cells that are specialised in recognizing infected cells, and are an essential part of the immune system. In the current study, published in the journal Science Immunology, the scientists assessed the role played by MAIT cells in COVID-19 disease. They examined the presence and character of MAIT cells in blood samples from 24 patients admitted to Karolinska University Hospital with moderate to severe COVID-19 disease, and compared these with blood samples from 14 healthy controls and 45 individuals who had recovered from COVID-19. Four of the patients died in the hospital, the study noted. "To find potential treatments against COVID-19, it is important to understand in detail how our immune system reacts, and in some cases, perhaps contribute to worsening the disease," said Johan Sandberg, a co-author of the study at Karolinska Institutet. According to the study, the number of MAIT cells in the blood decline sharply in patients with moderate or severe COVID-19, and the remaining cells in circulation are highly activated. Based on these results, the scientists suggested that the MAIT cells are engaged in the immune response against the novel coronavirus SARS-CoV-2. This pattern of reduced number and activation in the blood is stronger for MAIT cells than for other T cells, they said. The study also noted that pro-inflammatory MAIT cells accumulated in the airways of COVID-19 patients to a larger degree than in healthy people. "Taken together, these analyses indicate that the reduced number of MAIT cells in the blood of COVID-19 patients is at least partly due increased accumulation in the airways," Sandberg said. The scientists added that the number of MAIT cells in the blood of convalescent COVID-19 patients recovered at least partially in the weeks after disease, which can be important for managing bacterial infections in individuals who have had COVID-19. They said the MAIT cells tended to be extremely activated in the patients who died. "The findings of our study show that the MAIT cells are highly engaged in the immunological response against COVID-19," Sandberg said. The scientists believe the characteristics of MAIT cells make them engaged early on in both the systemic immune response, and in the local immune response in the airways to which they are recruited from the blood by inflammatory signals. "There, they are likely to contribute to the fast, innate immune response against the virus. In some people with COVID-19, the activation of MAIT cells becomes excessive and this correlates with severe disease," Sandberg added. Copyright © Jammu Links News, Source: Jammu Links News

Student develops UV-E SAFE kit to check COVID-19

a

A 23-year-old student, K. Goutam Kumar, has developed an UV-E SAFE kit that helps in sanitising money, documents, files and other belongings within a minute.

Kumar is pursuing entrepreneurship skills training from Bharatiya Skill Development University (BSDU).

Taking about his invention, Kumar said: "In times of a global pandemic like COVID-19, a sudden need to sanitise our belongings has emerged. These belongings could be mobiles, laptops or anything that we carry. We were also worried how academic material could be exchanged without the fear of infection. This was the reason behind this invention."

Describing the device, Prof Achintya Choudhury, President, BSDU, said, "It is a sanitation device that sterilises money, notes, documents, files and many more things that otherwise are impossible to sanitize through conventional means. The use of ultraviolet ensures that up to 99.9 per cent of bacteria and pathogens are killed in a minute.

"It's safe and moreover it is portable as the sleek design makes it easy to carry it around," he added.

"We cannot avoid carrying items such as mobile phone, jewellery, laptop or an innocuous appearing letter and all are possible carriers of the pathogens they come in contact with. It is not always possible to clean these things with a sanitizer. Hence, UV E-SAFE kit could prove a great boon."

"The kit can kill almost all types of bacteria and viruses. UV rays exposure can be controlled as well. The box has been made using a robust CKT design technology which makes it long lasting. Also, it has zero maintenance and hassle free installation," said Prof Ravi Kumar Goyal, Principal, School of Entrepreneurship Skills.(IANS) Source: https://southasiamonitor.org

Metal-Breathing Bacteria Could Transform Electronics, Biosensors, and More


When the Shewanella oneidensis bacterium “breathes” in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices.

The ability of this bacterium to produce molybdenum disulfide — a material that is able to transfer electrons easily, like graphene — is the focus of research published in Biointerphases by a team of engineers from Rensselaer Polytechnic Institute.
“This has some serious potential if we can understand this process and control aspects of how the bacteria are making these and other materials,” said Shayla Sawyer, an associate professor of electrical, computer, and systems engineering at Rensselaer.

The research was led by James Rees, who is currently a postdoctoral research associate under the Sawyer group in close partnership and with the support of the Jefferson Project at Lake George — a collaboration between Rensselaer, IBM Research, and The FUND for Lake George that is pioneering a new model for environmental monitoring and prediction. This research is an important step toward developing a new generation of nutrient sensors that can be deployed on lakes and other water bodies.

“We find bacteria that are adapted to specific geochemical or biochemical environments can create, in some cases, very interesting and novel materials,” Rees said. “We are trying to bring that into the electrical engineering world.”

Rees conducted this pioneering work as a graduate student, co-advised by Sawyer and Yuri Gorby, the third author on this paper. Compared with other anaerobic bacteria, one thing that makes Shewanella oneidensis particularly unusual and interesting is that it produces nanowires capable of transferring electrons.

“That lends itself to connecting to electronic devices that have already been made,” Sawyer said. “So, it’s the interface between the living world and the manmade world that is fascinating.”

Sawyer and Rees also found that, because their electronic signatures can be mapped and monitored, bacterial biofilms could also act as an effective nutrient sensor that could provide Jefferson Project researchers with key information about the health of an aquatic ecosystem like Lake George.

“This groundbreaking work using bacterial biofilms represents the potential for an exciting new generation of ‘living sensors,’ which would completely transform our ability to detect excess nutrients in water bodies in real-time. This is critical to understanding and mitigating harmful algal blooms and other important water quality issues around the world,” said Rick Relyea, director of the Jefferson Project.

Sawyer and Rees plan to continue exploring how to optimally develop this bacterium to harness its wide-ranging potential applications.

“We sometimes get the question with the research: Why bacteria? Or, why bring microbiology into materials science?” Rees said. “Biology has had such a long run of inventing materials through trial and error. The composites and novel structures invented by human scientists are almost a drop in the bucket compared to what biology has been able to do.”

Bacteria revived after 100 million years dormant


Ancient microbes from deep within the seafloor have been found to “revive and multiply” in the laboratory after laying dormant for more than 100 million years.

Scientists in the US and Japan have found that these deep-sea microorganisms were capable of growing and dividing, even after remaining in an energy-saving state since dinosaurs roamed the planet.

The researchers said their findings, published in the journal Nature Communications, initially took them by surprise.

Germs are the smallest species in the world. They can survive in difficult adversity; again, many powerful germs cannot survive. Scientists incubate dormant germs. This has increased the intake and number of germs.

Lead author Yuki Morono, from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), said: “Our main question was whether life could exist in such a nutrient-limited environment or if this was a lifeless zone. And we wanted to know how long the microbes could sustain their life in a near-absence of food.”

Study author Professor Steven D’Hondt, of the Graduate School of Oceanography, University of Rhode Island, US, said: “We knew that there was life in deep sediment near the continents where there’s a lot of buried organic matter.

“But what we found was that life extends in the deep ocean from the seafloor all the way to the underlying rocky basement.”

Previous research has shown how bacteria live in hostile environments. It can even survive without oxygen in the bottom of the ocean floor.

Morono also said that the new germs have shown that some of the world's most basic living structures "have no real idea of life span."Source: https://www.daily-bangladesh.com

Glowing nanoprobe detects mercury in bacteria, fish

The fish without the nanoprobe (above) and a confocal microscope image (below) of its body parts after the injection of the nanoprobe revealing the presence of mercury.

Indian researchers have synthesised a light-emitting nanoprobe that can detect minute traces of mercury in various water samples, bacteria and small fish1. The nanoprobe can also remove this toxic metal.

The nanoprobe, they say, is potentially useful for monitoring mercury levels in various fish, including edible ones that transport mercury to humans.
© Panda, S. et al.Fossil fuel burning and various industries emit mercury into the environment, from where it accumulates in fish and other aquatic animals, ending up in humans. Existing techniques for detecting mercury are expensive and complex.

Scientists from the National Institute of Technology in Rourkela and Orissa University of Agriculture and Technology in Bhubaneswar, invented the nanoprobe using modified carbon quantum dots and iron oxide nanoparticles. They then tested the nanoprobe’s efficiency in monitoring mercury in different water samples and in fish.

The researchers, led by Biswaranjan Paital, found that the nanoprobe emitted a feeble green signal in the absence of mercury. However, the green signal became intense in the presence of mercury. The intensity of the signal increased with increasing mercury concentration.

The nanoprobe exhibited a negligible signal in the presence of various metal ions such as sodium, potassium, magnesium and calcium, indicating that it could selectively bind to mercury ions in a solution. Since the nanoprobe contains magnetic nanoparticles, a mercury-attached nanoprobe could be separated using an external magnet.

At high concentrations, the nanoprobe was non-toxic to bacteria, showing that it is biocompatible. It successfully monitored mercury levels in different fish organs such as gills, muscles, the liver and the brain. It also detected mercury levels in bacteria, and tap and river water samples.

Nasa’s Perseverance to scour Mars for signs of life


A handout photo, released by Nasa, of engineers in a clean room at the Jet Propulsion Laboratory in Pasadena, California, observe the first driving test for the Perseverance rover late last year.
  • By Ivan Couronne, AFP Washington: Nasa’s most advanced Mars rover, Perseverance, launches from Earth on July 30, on a mission to seek out signs of ancient microbial life on what was once a river delta.
  • The interplanetary voyage will last six months.
  • Should the SUV-sized vehicle touch down unscathed, it will start collecting and storing rock and soil samples, to be retrieved by a future mission and brought back to Earth in 2031.
  • Perseverance follows in the tyre tracks of four rovers before it, all American, which first launched in the late 1990s.
  • Together with satellite and surface probes, they have transformed our understanding of Mars, showing that the Red Planet wasn’t always a cold and barren place.
  • Instead, it had the ingredients for life as we know it: water, organic compounds and a favourable climate.
  • Scientists will examine the samples obtained by Perseverance to look for fossilised bacteria and other microbes to try to confirm if aliens did once live on our neighbouring planet.
  • Nasa has been teleworking for months because of the Covid-19 pandemic, but the launch calendar for this $2.7bn mission hasn’t been affected.
  • “This mission was one of two missions that we protected to make sure that we were going to be able to launch in July,” said Nasa chief Jim Bridestine.
  • Earth and Mars are on the same side of the Sun every 26 months, a window that can’t be missed.
  • The United States is the only country on the planet to have successfully landed robots on Mars: four landers, which aren’t mobile, and the rovers Pathfinder, Spirit, Opportunity and Curiosity.
  • Of the rovers, only Curiosity is still active, with the others left on the surface after their machinery failed or contact was lost.
  • It’s only in the past two decades that it’s been confirmed Mars once had oceans, rivers and lakes.
  • Curiosity confirmed the presence of complex organic molecules — but its instruments aren’t capable of concluding that they were created by biological processes.
  • The first two landers, Viking 1 and 2, both looked for signs of life as far back as 1976, but haphazardly.
  • “At the time the experiment for life detection was considered to be a complete failure,” said G Scott Hubbard, who launched the current Mars exploration programme in the 2000s.
  • Nasa then decided to proceed in stages.
  • By studying the soil, analysing the molecular composition of rocks, and carrying out satellite observations, geologists and astrobiologists gradually understood where water had flowed, and what areas could have been conducive to life.
  • “Understanding where Mars would have been habitable in the past, and what kind of fingerprints of life you’re looking for, was a necessary precursor to then going, at significant expense, to this very well selected spot that would produce these samples,” said Hubbard.
  • On February 18, 2021, Perseverance should land in the Jezero Crater, home to an ancient river that fanned out into a lake between 3bn and 4bn years ago, depositing mud, sand and sediment.
  • “Jezero is host to one of the best preserved deltas on the surface of Mars,” said Katie Stack Morgan, a member of the science team.
  • On Earth, scientists have found the fossilised remains of bacteria billions of years old in similar ancient deltas.
  • The six-wheeled rover is 3m long, weighs a ton, has 19 cameras, two microphones and a two-meter-long robotic arm.
  • Its most important instruments are two lasers and an X-ray which, when projected on rocks, can analyse their chemical composition and identify possible organic compounds.
  • Also on board is the experimental mini-helicopter Ingenuity, which weighs 1.8kg. Nasa hopes it will be the first chopper to take flight on another planet.
  • Perseverance probably won’t be able to determine whether a rock has ancient microbes.
  • To know for sure, the samples will have to be brought back to Earth where they can be cut into ultra-thin slices.
  • “Getting true scientific consensus...that life once existed on Mars, I think that would still require a sample return,” Ken Williford, deputy head of the science project told AFP.
  • One thing we shouldn’t expect are the fossilised shells that people find on Earth, he added.
  • If life once did exist on Mars, it probably didn’t have time to evolve into more complex organisms before the planet dried up completely. Source: https://www.gulf-times.com

How Did Early Earth Stay Warm?

A UC Riverside-led astrobiology team discovered that methane, a potent greenhouse gas, was not the climate savior once imagined for the mysterious middle chapter of Earth history For at least a billion years of the distant past, planet Earth should have been frozen over but wasn’t. Scientists thought they knew why, but a new modeling study from the Alternative Earths team of the NASA Astrobiology Institute has fired the lead actor in that long-accepted scenario. Humans worry about greenhouse gases, but between 1.8 billion and 800 million years ago, microscopic ocean dwellers really needed them. The sun was 10 to 15 percent dimmer than it is today—too weak to warm the planet on its own. Earth required a potent mix of heat-trapping gases to keep the oceans liquid and livable. For decades, atmospheric scientists cast methane in the leading role. The thinking was that methane, with 34 times the heat-trapping capacity of carbon dioxide, could have reigned supreme for most of the first 3.5 billion years of Earth history, when oxygen was absent initially and little more than a whiff later on. (Nowadays oxygen is one-fifth of the air we breathe, and it destroys methane in a matter of years.) “A proper accounting of biogeochemical cycles in the oceans reveals that methane has a much more powerful foe than oxygen,” said Stephanie Olson, a graduate student at the University of California, Riverside, a member of the Alternative Earths team and lead author of the new study published September 26 in the Proceedings of the National Academy of Sciences. “You can’t get significant methane out of the ocean once there is sulfate.” Sulfate wasn’t a factor until oxygen appeared in the atmosphere and triggered oxidative weathering of rocks on land. The breakdown of minerals such as pyrite produces sulfate, which then flows down rivers to the oceans. Less oxygen means less sulfate, but even 1 percent of the modern abundance is sufficient to kill methane, Olson said. Stephanie Olson and Tim Lyons next to an image of visualizations of sulfate concentrations (top) and methane destruction (bottom) from their biogeochemical model of Earth’s ocean and atmosphere roughly one billion years ago.

Olson and her Alternative Earths coauthors, Chris Reinhard, an assistant professor of earth and atmospheric sciences at Georgia Tech University, and Timothy Lyons, a distinguished professor of biogeochemistry at UC Riverside, assert that during the billion years they assessed, sulfate in the ocean limited atmospheric methane to only 1 to 10 parts per million—a tiny fraction of the copious 300 parts per million touted by some previous models. The fatal flaw of those past climate models and their predictions for atmospheric composition, Olson said, is that they ignore what happens in the oceans, where most methane originates as specialized bacteria decompose organic matter. Seawater sulfate is a problem for methane in two ways: Sulfate destroys methane directly, which limits how much of the gas can escape the oceans and accumulate in the atmosphere. Sulfate also limits the production of methane. Life can extract more energy by reducing sulfate than it can by making methane, so sulfate consumption dominates over methane production in nearly all marine environments. The numerical model used in this study calculated sulfate reduction, methane production, and a broad array of other biogeochemical cycles in the ocean for the billion years between 1.8 billion and 800 million years ago. This model, which divides the ocean into nearly 15,000 three-dimensional regions and calculates the cycles for each region, is by far the highest resolution model ever applied to the ancient Earth. By comparison, other biogeochemical models divide the entire ocean into a two-dimensional grid of no more than five regions. “There really aren’t any comparable models,” says Reinhard, who was lead author on a related paper in Proceedings of the National Academy of Sciences that described the fate of oxygen during the same model runs that revealed sulfate’s deadly relationship with methane. Reinhard notes that oxygen dealt methane an additional blow, based on independent evidence published recently by the Alternative Earths team in the journals Science and Geology. These papers describe geochemical signatures in the rock record that track extremely low oxygen levels in the atmosphere, perhaps much less than 1 percent of modern values, up until about 800 million years ago, when they spiked dramatically. Less oxygen seems like a good thing for methane, since they are incompatible gases, but with oxygen at such extremely low levels, another problem arises. “Free oxygen [O2] in the atmosphere is required to form a protective layer of ozone [O3], which can shield methane from photochemical destruction,” Reinhard said. When the researchers ran their model with the lower oxygen estimates, the ozone shield never formed, leaving the modest puffs of methane that escaped the oceans at the mercy of destructive photochemistry. With methane demoted, scientists face a serious new challenge to determine the greenhouse cocktail that explains our planet’s climate and life story, including a billion years devoid of glaciers, Lyons said. Knowing the right combination other warming agents, such as water vapor, nitrous oxide, and carbon dioxide, will also help us assess habitability of the hundreds of billions of other Earth-like planets estimated to reside in our galaxy. “If we detect methane on an exoplanet, it is one of our best candidates as a biosignature, and methane dominates many conversations in the search for life on Mars,” Lyons said. “Yet methane almost certainly would not have been detected by an alien civilization looking at our planet a billion years ago—despite the likelihood of its biological production over most of Earth history.”

Rust under Pressure Could Explain Deep Earth Anomalies

Courtesy of Ms. Xiaoya.
Using laboratory techniques to mimic the conditions found deep inside the Earth, a team of Carnegie scientists led by Ho-Kwang "Dave" Mao has identified a form of iron oxide that they believe could explain seismic and geothermal signatures in the deep mantle. Their work is published in Nature. Iron and oxygen are two of the most geochemically important elements on Earth. The core is rich in iron and the atmosphere is rich in oxygen, and between them is the entire range of pressures and temperatures on the planet. An artwork depicting the decomposition of FeOOH in lower mantle conditions. The cycle starts from α-FeOOH (blue dot on the top) to its high-pressure form (brown dot), to FeO2 (center crystal) and hydrogen (cyan bubbles), and finally produce other minerals (bubbles on the left side). "Interactions between oxygen and iron dictate Earth's formation, differentiation--or the separation of the core and mantle--and the evolution of our atmosphere, so naturally we were curious to probe how such reactions would change under the high-pressure conditions of the deep Earth," said Mao. The research team--Qingyang Hu, Duck Young Kim, Wenge Yang, Liuxiang Yang, Yue Meng, Li Zhang, & Ho-Kwang Mao--put ordinary rust, or FeOOH, under about 900,000 times normal atmospheric pressure and at about 3200 degrees Fahrenheit and were able to synthesize a form of iron oxide, FeO2, that structurally resembles pyrite, also known as fool's gold. The reaction gave off hydrogen in the form of H2. FeOOH is found in iron ore deposits that exist in bogs, so it could easily move into the deep Earth at plate tectonic boundaries, as could samples of ferric oxide, Fe2O3, which along with water will also form the pyrite-like iron oxide under deep lower mantle conditions. Why does this interest the researchers? For one thing, this type of reaction could have started in Earth's infancy, and understanding it could inform theories of our own planet's evolution, as well as its current geochemistry. Furthermore, the H2 released in this reaction would work its way upward, possibly reacting with other materials on its way. Meanwhile, the iron oxide would settle planet's depths and form reservoirs of oxygen there, particularly if one of these patches of iron oxide moved upward along the pressure gradient to the middle part of the mantle and separated into iron and O2. "Pools of free oxygen under these conditions could create many reactions and chemical phases, which might be responsible for seismic and geochemical signatures of the deep Earth," Mao explained. "Our experiments mimicking mantle conditions demonstrate that more research is needed on this pyrite-like phase of iron oxide." Hu added. The research team believes their findings could even offer an alternate explanation for the Great Oxygenation Event that changed Earth's atmosphere between 2 and 2.5 billion years ago. The rise of bacteria performing photosynthesis, which releases oxygen as a byproduct, is often considered the source of the rapid increase in atmospheric oxygen, which had previously been scarce. But releases of oxygen from upwelling of deep mantle FeO2 patches could provide an abiotic explanation for the phenomenon, they say.

Nanosubmarines powered by light

Nano-scale submarines built from 244 atoms and capable of moving at 2 cm per second have been demonstrated by Rice University. Credit: Loïc Samuel/Rice University
In a study published by Nano Letters, scientists from Rice University in Texas describe how they built and tested nanoscale submarines, which are able to move with incredible speed. The single-molecule, 244-atom submersibles each have a motor powered by ultraviolet light. With each full revolution the motor's tail-like propeller drives the sub forwards a distance of 18 nanometres (nm). However, the motors run at over a million RPM, giving a top speed of nearly two centimetres (0.8 inches) per second: a breakneck pace on the molecular scale. "These are the fastest-moving molecules ever seen in solution," says chemist James Tour, one of the study authors. While they can't be steered yet, the study has proved that molecular motors are powerful enough to drive the sub-10-nanometre craft through solutions of moving molecules of about the same size. From a nano-scale point of view, "this is akin to a person walking across a basketball court with 1,000 people throwing basketballs at him," Tour said. Tour's group has extensive experience with molecular machines. A decade ago, his lab demonstrated nanocars – single-molecule cars with four wheels, axles and independent suspensions that could be "driven" across a surface. Over the years, many research groups have created microscopic machines featuring motors – but most have either used or generated toxic chemicals. A motor conceived in the last decade by Dutch researchers proved suitable for the Rice submersibles, which were produced in a 20-step chemical synthesis. "These motors are well-known and used for different things," said Victor García-López, lead author and Rice graduate student. "But we were the first to propose they can be used to propel nanocars

– and now submersibles." The motors, which operate more like a bacteria's flagellum than a propeller, complete each revolution in four steps. When excited by light, the double bond that holds the rotor to the body becomes a single bond, allowing it to rotate a quarter step. As the motor seeks to return to a lower energy state, it jumps adjacent atoms for another quarter turn. This process repeats as long as the light is on. Once built, the team turned to Gufeng Wang at North Carolina State University to measure how well the nanosubs moved. "We had used scanning tunnelling microscopy and fluorescence microscopy to watch our cars drive, but that wouldn't work for the submersibles," explained Tour. "They would drift out of focus pretty quickly." The North Carolina team sandwiched a drop of diluted acetonitrile liquid containing a few nanosubs between two slides, then used a custom confocal fluorescence microscope to hit it from opposite sides with both ultraviolet light (for the motor) and a red laser (for the pontoons). The microscope's laser defined a column of light in the solution, in which tracking occurred, García-López said: "That way, the NC State team could guarantee it was analysing only one molecule at a time." The team hopes future nanosubs will be able to carry cargoes for medical and other purposes. "There's a path forward," García-López said. "This is the first step, and we've proven the concept. Now we need to explore opportunities and potential applications."Nanosubmarines powered by light

New drug may protect against deadly nuclear radiation

New drug may protect against deadly nuclear radiation
Washington: In a breakthrough, scientists have discovered a drug that may combat the deadly effects of nuclear radiation even after 24 hours of exposure. A single injection of the investigative peptide drug TP508 given 24 hours after a potentially-lethal exposure to radiation significantly increased survival and delayed mortality in mice by counteracting damage to the gastrointestinal system. The threat of a nuclear incident, with the potential to kill or injure thousands of people, has raised global awareness about the need for counter measures that can prevent radiation-induced bodily damage and keep people alive, even if given a day or more after contact with nuclear radiation. Exposure to high doses of radiation triggers a number of potentially lethal effects. Among the most severe of these effects is the gastrointestinal, or GI, toxicity syndrome that is caused by radiation-induced destruction of the intestinal lining. This type of GI damage decreases the ability of the body to absorb water and causes electrolyte imbalances, bacterial infection, intestinal leakage, sepsis and death. The GI toxicity syndrome is triggered by radiation-induced damage to crypt cells in the small intestines and colon that must continuously replenish in order for the GI tract to work properly. Crypt cells are especially susceptible to radiation damage and serve as an indicator of whether someone will survive after total body radiation exposure. “Because radiation-induced damage to the intestines plays such a key role in how well a person recovers from radiation exposure, it's crucial to develop novel medications capable of preventing GI damage," said Darrell Carney, a professor at University of Texas Medical Branch (UTMB). "The peptide drug TP508 was developed for use in stimulating repair of skin, bone and muscle tissues," said Carney, who is also the CEO of Chrysalis BioTherapeutics, Inc. It has previously been shown to begin tissue repair by stimulating proper blood flow, reducing inflammation and reducing cell death.In human clinical trials, the drug has been reported to increase healing of diabetic foot ulcers and wrist fractures with no drug-related adverse events. "The current results suggest that the peptide may be an effective emergency nuclear counter-measure that could be delivered within 24 hours after exposure to increase survival and delay mortality, giving victims time to reach facilities for advanced medical treatment," said lead author Carla Kantara, a postdoctoral fellow from UTMB. The study was published in the journal Laboratory Investigation. — PTI Source: Article

How Plants Help Each Other Grow By Near-Telepathic Communication

Plants have scientifically been show to draw alternative sources of energy from other plants. Plants influence each other in many ways and they communicate through “nanomechanical oscillations” vibrations on the tiniest atomic or molecular scale or as close as you can get to telepathic communication. Members of Professor Dr. Olaf Kruse’s biological research team have previously shown that green algae not only engages in photosynthesis, but also has an alternative source of energy: it can draw it from other plants. His research findings were released in the online journal Nature CommunicationsOther research published last year, showed that young corn roots made clicking sounds, and that when suspended in water they would lean towards sounds made in the same frequency range (about 220 Hz). So it seemed that plants do emit and react to sound, and the researchers wanted to delve into this idea further. Working with chili plants in their most recent study, specifically Capsicum annuum, they first grew chili seeds on their own and then in the presence of other chili plants, basil and fennel, and recorded their rates of germination and growth. Fennel is considered an aggressive plant that hinders the germination of other plants around it, while basil is generally considered to be a beneficial plant for gardening and an ideal companion for chili plants. Germination rates were fairly low when the seeds were grown on their own, lower when grown in the presence of fennel (as expected). Germination rates were better with other chili plants around, and even better with basil. Since plants are already known to ‘talk’ through chemical signals and to react to light, the researchers separated newly planted seeds from the other plants using black plastic, to block any other kind of ‘signaling’ other than through sound. When fennel was on the other side of the plastic, the chemical effects of its presence, which would have inhibited germination of the chili seeds, were blocked. The chili seeds grew much quicker than normal though, possibly because they still ‘knew’ the fennel was there, ‘knew’ it had the potential to have a negative effect on their germination, and so they quickly got past the stage where they were vulnerable. If even bacteria can signal one another with vibrations, why not plants, said Monica Gagliano, a plant physiologist at the University of Western Australia in Crawley. Gagliano imagines that root-to-root alerts could transform a forest into an organic switchboard. “Considering that entire forests are all interconnected by networks of fungi, maybe plants are using fungi the way we use the Internet and sending acoustic signals through this Web. From here, who knows,” she said. As with other life, if plants do send messages with sound, it is one of many communication tools. More work is needed to bear out Gagliano’s claims, but there are many ways that listening to plants already bears fruit. According to the study: “This demonstrated that plants were able to sense their neighbours even when all known communication channels are blocked (i.e. light, chemicals and touch) and most importantly, recognize the potential for the interfering presence of a ‘bad neighbour’ and modify their growth accordingly.” Then, to test if they could see similar effects with a ‘good neighbour’, they tried the same experiment with other chili plants and then with basil. When there were fully-grown chili plants in their presence blocked by the plastic, the seeds showed some improved germination (“partial response”). When basil was on the other side of the plastic, they found that the seeds grew just as well as when the plastic wasn’t there. “Our results show that plants are able to positively influence growth of seeds by some as yet unknown mechanism,” said Dr. Monica Gagliano, an evolutionary biologist at UWA and co-author of the study, according to BioMed Central. “Bad neighbors, such as fennel, prevent chili seed germination in the same way. We believe that the answer may involve acoustic signals generated using nanomechanical oscillations from inside the cell which allow rapid communication between nearby plants.” What Can Humans Learn? Flowers need water and light to grow and people are no different. Our physical bodies are like sponges, soaking up the environment. “This is exactly why there are certain people who feel uncomfortable in specific group settings where there is a mix of energy and emotions,” said psychologist and energy healer Dr. Olivia Bader-Lee. “When energy studies become more advanced in the coming years, we will eventually see this translated to human beings as well,“ stated Bader-Lee. “The human organism is very much like a plant, it draws needed energy to feed emotional states and this can essentially energize cells or cause increases in cortisol and catabolize cells depending on the emotional trigger.”
Bader-Lee suggests that the field of bio-energy is now ever evolving and that studies on the plant and animal world will soon translate and demonstrate what energy metaphysicians have known all along — that humans can heal each other simply through energy transfer just as plants do. “Human can absorb and heal through other humans, animals, and any part of nature. That’s why being around nature is often uplifting and energizing for so many people,” she concluded. Michael Forrester is a spiritual counselor and is a practicing motivational speaker for corporations in Japan, Canada and the United States.

Alien Life on Earth? 'Little Bugs' microbe discovery: NASA

The discovery of a strange bacteria that can use arsenic as one of its nutrients widens the scope for finding new forms of life on Earth and possibly beyond, NASA scientists said on Thursday. While researchers discovered the unusual bacteria here on Earth, they say it shows that life has possibilities beyond the major elements that have been considered essential. Six major elements have long been considered essential for life - carbon, hydrogen, nitrogen, oxygen, phosphorus and sulphur. At a news conference on Thursday at NASA headquarters in Washington, researchers announced that they had found that a bacteria, discovered in Mono Lake, California, is able to continue to grow after substituting arsenic for phosphorus.

NASA scientist finds evidence of alien life?

We are not alone in the universe, says NASA astrobiologist Dr. Richard B. Hoover. And he claims to have the extraterrestrial fossils to back it up. Aliens exist, and we have proof. That astonishingly awesome claim comes from Dr. Richard B. Hoover, an astrobiologist at NASA’s Marshall Space Flight Center, who says he has found conclusive evidence of alien life — fossils of bacteria found in an extremely rare class of meteorite called CI1 carbonaceous chondrites. (There are only nine such meteorites on planet Earth.) Hoover’s findings were published late Friday night in the Journal of Cosmology, a peer-reviewed scientific
journal. A photograph taken through a scanning electron microscope of a CI1 meteorite (right) is similar in size and overall structure to the giant bacterium Titanospirillum velox (left), an organism found here on planet Earth, a NASA scientist said. Riccardo Guerrero / Richard B. Hoover / Journal of Cosmology “I interpret it as indicating that life is more broadly distributed than restricted strictly to the planet earth,” Hoover, who has spent more than 10 years studying meteorites around the world, told FoxNews.com in an interview. “This field of study has just barely been touched — because quite frankly, a great many scientist would say that this is impossible.” Hoover discovered the fossils by breaking apart the CI1 meteorite, and analyzing the exposed rock with a scanning-electron microscope and a field emission electron-scanning microscope, which allowed him to detect any fossil remains. What he found were fossils of micro-organisms, many of which he says are strikingly similar to those found on our own planet. “The exciting thing is that they are in many cases recognizable and can be associated very closely with
the generic species here on earth,” said Hoover. Some of the fossils, however, are quite odd. “There are some that are just very strange and don’t look like anything that I’ve been able to identify, and I’ve shown them to many other experts that have also come up stump.” In order to satisfy the inevitable hoard of buzz-killing skeptics, Hoover’s study and evidence were made available to his peers in the scientific community in advance of the study’s publications, giving them a chance to thoroughly dissect his findings. Comments from those who decided to sift through the evidence will be published online, alongside the study. “Given the controversial nature of his discovery, we have invited 100 experts and have issued a general invitation to over 5,000 scientists from the scientific community to review the paper and to offer their critical analysis,” writes Harvard-Smithsonian Center for Astrophysics scientist Dr. Rudy Schild, who serves as the Journal of Cosmology’s editor-in-chief. “No other paper in the history of science has undergone such a thorough vetting, and never before in the history of science has the scientific community been given the opportunity to critically analyze an important research paper before it is published.” Needless to say, if Hoover’s conclusions are found to be accurate, the implications for human life will be staggering. Here’s hoping that he’s right. Update: While the Journal of Cosmology says that “no other paper in the history of science has undergone such a thorough vetting,” some highly respected names in the scientific community are challenging the validity of Cosmology, and the findings of Dr. Hoover. “[The Journal of Cosmology] isn’t a real science journal at all,” says PZ Meyers in Science Blogs, “but is the ginned-up website of a small group of crank academics obsessed with the idea of Hoyle and Wickramasinghe that life originated in outer space and simply rained down on Earth.” So there you have it — this is either reality-altering news, or the work of kooks. Our hearts believe, but our brains are kind of bummed. Source: Article

World Changing Technology Lets Crops To Take Nitrogen From The Air

A major new technology has been developed by The University of Nottingham, which enables all of the world’s crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers. Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital for plants to survive and grow. However, only a very small number of plants, most notably legumes (such as peas, beans and lentils) have the ability to fix nitrogen from the atmosphere with the help of nitrogen fixing bacteria. The vast majority of plants have to obtain nitrogen from the soil, and for most crops currently being grown across the world, this also means a reliance on synthetic nitrogen fertiliser. Professor Edward Cocking, Director of The University of Nottingham’s Centre for Crop Nitrogen Fixation, has developed a unique method of putting nitrogen-fixing bacteria into the cells of plant roots. His major breakthrough came when he found a specific strain of nitrogen-fixing bacteria in sugar-cane which he discovered could intracellularly colonise all major crop plants. This ground-breaking development potentially provides every cell in the
plant with the ability to fix atmospheric nitrogen. The implications for agriculture are enormous as this new technology can provide much of the plant’s nitrogen needs. A leading world expert in nitrogen and plant science, Professor Cocking has long recognised that there is a critical need to reduce nitrogen pollution caused by nitrogen based fertilisers. Nitrate pollution is a major problem as is also the pollution of the atmosphere by ammonia and oxides of nitrogen. In addition, nitrate pollution is a health hazard and also causes oxygen-depleted ‘dead zones’ in our waterways and oceans. A recent study estimates that that the annual cost of damage caused by nitrogen pollution across Europe is £60 billion — £280 billion a year.1 Speaking about the technology, which is known as ‘N-Fix’, Professor Cocking said: “Helping plants to naturally obtain the nitrogen they need is a key aspect of World Food Security. The world needs to unhook itself from its ever increasing reliance on synthetic nitrogen fertilisers produced from fossil fuels with its high economic costs, its pollution of the environment and its high energy costs.” N-Fix is neither genetic modification nor bio-engineering. It is a naturally occurring nitrogen fixing bacteria which takes up and uses nitrogen from the air. Applied to the cells of plants (intra-cellular) via the seed, it provides every cell in the plant with the ability to fix nitrogen. Plant seeds are coated with these bacteria in order to create a symbiotic, mutually beneficial relationship and naturally produce nitrogen. N-Fix is a natural nitrogen seed coating that provides a sustainable solution to fertiliser overuse and Nitrogen pollution. It is environmentally friendly and can be applied to all crops. Over the last 10 years, The University of Nottingham has conducted a series of extensive research programmes which have established proof of principal of the technology in the laboratory, growth rooms and glasshouses.  The University of Nottingham’s Plant and Crop Sciences Division is internationally acclaimed as a centre for fundamental and applied research, underpinning its understanding of agriculture, food production and quality, and the natural environment. It also has one of the largest communities of plant scientists in the UK.  Dr Susan Huxtable, Director of Intellectual Property Commercialisation at The University of Nottingham, believes that the N-Fix technology has significant implications for agriculture, she said: “There is a substantial global market for the N-Fix technology, as it can be applied globally to all crops. N-Fix has the power to transform agriculture, while at the same time offering a significant cost benefit to the grower through the savings that they will make in the reduced costs of fertilisers. It is a great example of how University research can have a world-changing impact.” The N-Fix technology has been licensed by The University of Nottingham to Azotic Technologies Ltd to develop and commercialise N-Fix globally on its behalf for all crop species. Peter Blezard, CEO of Azotic Technologies added: “Agriculture has to change and N-Fix can make a real and positive contribution to that change. It has enormous potential to help feed more people in many of the poorer parts of the world, while at the same time, dramatically reducing the amount of synthetic nitrogen produced in the world.” The proof of concept has already been demonstrated. The uptake and fixation of nitrogen in a range of crop species has been proven to work in the laboratory and Azotic is now working on field trials in order to produce robust efficacy data. This will be followed by seeking regulatory approval for N-Fix initially in the UK, Europe, USA, Canada and Brazil, with more countries to follow. It is anticipated that the N-Fix technology will be commercially available within the next two to three years.

Intelligent Alien Dinosaurs?

Dinosaurs once roamed and ruled the Earth. Is it possible that similar humongous creatures may have evolved on another planet – a world that DIDN’T get smacked by an asteroid – and later they developed to have human-like, intelligent brains? A recent paper discussing why the biochemical signature of life on Earth is so consistent in orientation somehow segued into the possibility that advanced versions of T. Rex and other dinosaurs may be the life forms that live on other worlds. The conclusion? “We would be better off not meeting them,” said scientist Ronald Breslow, author of the paper. The building blocks of terrestrial amino acids, sugars, and the genetic materials DNA and RNA have two possible orientations, left or right, which mirror each other in what is called chirality. On Earth, with the exception of a few bacteria, amino acids have the left-handed orientation. Most sugars have a right-handed orientation. How did that homochirality happen? If meteorites carried specific types of amino acids to Earth about 4 billion years, that could have set the pattern the left-handed chirality in terrestial proteins. “Of course,” Breslow said in a press release, “showing that it could have happened this way is not the same as showing that it did. An implication from this work is that elsewhere in the universe there could be life forms based on D-amino acids and L-sugars. Such life forms could well be advanced versions of dinosaurs, if mammals did not have the good fortune to have the dinosaurs wiped out by an asteroidal collision, as on Earth.” But not everyone was impressed with the notion of dinosaurs from space. “None of this has anything to do with dinosaurs,” wrote science author Brian Switek in the Smithsonian blog Dinosaur Tracking. “As much as I’m charmed by the idea of alien dinosaurs, Breslow’s conjecture makes my brain ache. Our planet’s fossil record has intricately detailed the fact that evolution is not a linear march of progress from one predestined waypoint to another. Dinosaurs were never destined to be. The history of life on earth has been greatly influenced by chance and contingency, and dinosaurs are a perfect example of this fact.” For further reading: American Chemical Society paperACS press releaseDinosaur Tracking blogSource: Article

Electricity generated from harmless viruses

Scientists including one of an Indian origin have made a breakthrough that could lead to tiny devices that harvest electrical energy from the vibrations of everyday tasks such as shutting a door or climbing stairs. Berkeley Lab scientists have found a way to make harmless viruses harvest mechanical energy, which could then be used, say, to charge a phone as its owner walks along. They've created a generator that produces enough current to operate a small liquid-crystal display. It harvests energy when the user taps a finger on a postage stamp-sized electrode coated with specially engineered viruses which convert the force of the tap into an electric charge. The generator is the first to produce electricity by harnessing the piezoelectric properties of a biological material. It could replace the use of highly-toxic chemicals in
current piezoelectric devices. It could also lead to a simpler way to make microelectronic devices, as the viruses self-assemble into an orderly film. "More research is needed, but our work is a promising first step toward the development of personal power generators, actuators for use in nano-devices, and other devices based on viral electronics," says Seung-Wuk of Berkeley Lab and UC Berkeley. The M13 bacteriophage only attacks bacteria and is benign to people. It replicates itself by the millions within hours, so there's always a steady supply, and it's easy to genetically engineer. When pressure is applied to the generator, it produces up to six nanoamperes of current and 400 millivolts of potential - about a quarter the voltage of a triple A battery. "We're now working on ways to improve on this proof-of-principle demonstration," says Lee. "Because the tools of biotechnology enable large-scale production of genetically modified viruses, piezoelectric materials based on viruses could offer a simple route to novel microelectronics in the future."Source: Technology Update

Scientists Announce Top 10 New Species

Credit: Composite: Jacob Sahertian
An amazing glow-in-the-dark cockroach, a harp-shaped carnivorous sponge and the smallest vertebrate on Earth are just three of the newly discovered top 10 species selected by the International Institute for Species Exploration at Arizona State University. A global committee of taxonomists — scientists responsible for species exploration and classification — announced its list of top 10 species from 2012 today, May 23. The announcement, now in its sixth year, coincides with the anniversary of the birth of Carolus Linnaeus — the 18th century Swedish botanist responsible for the modern system of scientific names and classifications. The top 10 new species list was announced May 23 by the International Institute for Species Exploration at Arizona State University. The 2013 list includes an amazing glow-in-the-dark cockroach, a harp-shaped carnivorous sponge, and the smallest vertebrate on Earth -- a tiny frog. It also includes a snail-eating false coral snake, flowering bushes, a green lacewing, a hangingfly fossil, a monkey with a blue-colored behind and human-like eyes, a tiny violet and a black staining fungus. Also slithering it way onto this year's top 10 is a snail-eating false coral snake, as well as flowering bushes from a disappearing forest in Madagascar, a green lacewing that was discovered through social media and hangingflies that perfectly mimicked ginkgo tree leaves 165 million years ago. Rounding out the list is a new monkey with a blue-colored behind and human-like eyes, a tiny violet and a black staining fungus that threatens rare Paleolithic cave paintings in France. "We have identified only about two million of an estimated 10 to 12 million living species and that does not count most of the microbial world," said Quentin Wheeler, founding director of the International Institute for Species Exploration at ASU and author of "What on Earth? 100 of our Planet's Most Amazing New Species" (NY, Plume, 2013). "For decades, we have averaged 18,000 species discoveries per year which seemed reasonable before the biodiversity crisis. Now, knowing that millions of species may not survive the 21st century, it is time to pick up the pace," Wheeler added. "We are calling for a NASA-like mission to discover 10 million species in the next 50 years. This would lead to discovering countless options for a more sustainable future while securing evidence of the origins of the biosphere," Wheeler said. Taxon experts pick top 10: Members of the international committee made their top 10 selection from more than 140 nominated species. To be considered, species must have been described in compliance with the appropriate code of nomenclature, whether botanical, zoological or microbiological, and have been officially named during 2012.  "Selecting the final list of new species from a wide representation of life forms such as bacteria, fungi, plants and animals, is difficult. It requires finding an equilibrium between certain criteria and the special insights revealed by selection committee members," said Antonio Valdecasas, a biologist and research zoologist with Museo Nacional de Ciencias Naturales in Madrid, Spain. Valdecasas is the international selection committee chairman for the top 10 new species. "We look for organisms with unexpected features or size and those found in rare or difficult to reach habitats. We also look for organisms that are especially significant to humans — those that play a certain role in human habitat or that are considered a close relative," Valdecasas added. This year's top 10 come from Peru; NE Pacific Ocean, USA: California; Democratic Republic of the Congo; Panama; France; New Guinea; Madagascar; Ecuador; Malaysia; and China. Top 10 New Species, 2013, "I don't know whether to be more astounded by the species discovered each year, or the depths of our ignorance about biodiversity of which we are a part," shared Wheeler. "At the same time we search the heavens for other earthlike planets, we should make it a high priority to explore the biodiversity on the most earthlike planet of them all: Earth," he added. "With more than eight out of every 10 living species awaiting discovery, I am shocked by our ignorance of our very own planet and in awe at the diversity, beauty and complexity of the biosphere and its inhabitants."
Describing the discoveries
Lilliputian Violet 
Viola lilliputana 
Country: Peru
Tiny violet: Not only is the Lilliputian violet among the smallest violets in the world, it is also one of the most diminutive terrestrial dicots. Known only from a single locality in an Intermontane Plateau of the high Andes of Peru, Viola lilliputana lives in the dry puna grassland eco-region. Specimens were first collected in the 1960s, but the species was not described as a new until 2012. The entire above ground portion of the plant is barely 1 centimeter tall. Named, obviously, for the race of little people on the island of Lilliput in Jonathan Swift's Gulliver's Travels.
Lyre Sponge 
Chondrocladia lyra 
Country: NE Pacific Ocean; USA: California
Carnivorous sponge: A spectacular, large, harp- or lyre-shaped carnivorous sponge discovered in deep water (averaging 3,399 meters) from the northeast Pacific Ocean off the coast of California. The harp-shaped structures or vanes number from two to six and each has more than 20 parallel vertical branches, often capped by an expanded, balloon-like, terminal ball. This unusual form maximizes the surface area of the sponge for contact and capture of planktonic prey.
Lesula Monkey 
Cercopithecus lomamiensis 
Country: Democratic Republic of the Congo
Old World monkey: Discovered in the Lomami Basin of the Democratic Republic of the Congo, the lesula is an Old World monkey well known to locals but newly known to science. This is only the second species of monkey discovered in Africa in the past 28 years. Scientists first saw the monkey as a captive juvenile in 2007. Researchers describe the shy lesula as having human-like eyes. More easily heard than seen, the monkeys perform a booming dawn chorus. Adult males have a large, bare patch of skin on the buttocks, testicles and perineum that is colored a brilliant blue. Although the forests where the monkeys live are remote, the species is hunted for bush meat and its status is vulnerable.
No to the Mine! Snake 
Sibon noalamina 
Country: Panama
Snail-eating snake: A beautiful new species of snail-eating snake has been discovered in the highland rainforests of western Panama. The snake is nocturnal and hunts soft-bodied prey including earthworms and amphibian eggs, in addition to snails and slugs. This harmless snake defends itself by mimicking the alternating dark and light rings of venomous coral snakes. The species is found in the Serranía de Tabasará mountain range where ore mining is degrading and diminishing its habitat. The species name is derived from the Spanish phrase "No a la mina" or "No to the mine."
A Smudge on Paleolithic Art 
Ochroconis anomala 
Country: France
Fungus: In 2001, black stains began to appear on the walls of Lascaux Cave in France. By 2007, the stains were so prevalent they became a major concern for the conservation of precious rock art at the site that dates back to the Upper Paleolithic. An outbreak of a white fungus, Fusarium solani, had been successfully treated when just a few months later, black staining fungi appeared. The genus primarily includes fungi that occur in the soil and are associated with the decomposition of plant matter. As far as scientists know, this fungus, one of two new species of the genus from Lascaux, is harmless. However, at least one species of the group, O. gallopava, causes disease in humans who have compromised immune systems.
World's Smallest Vertebrate 
Paedophryne amanuensis 
Country: New Guinea
Tiny frog: Living vertebrates — animals that have a backbone or spinal column — range in size from this tiny new species of frog, as small as 7 millimeters, to the blue whale, measuring 25.8 meters. The new frog was discovered near Amau village in Papua, New Guinea. It captures the title of 'smallest living vertebrate' from a tiny Southeast Asian cyprinid fish that claimed the record in 2006. The adult frog size, determined by averaging the lengths of both males and females, is only 7.7 millimeters. With few exceptions, this and other ultra-small frogs are associated with moist leaf litter in tropical wet forests — suggesting a unique ecological guild that could not exist under drier circumstances.
Endangered Forest 
Eugenia petrikensis 
Country: Madagascar
Endangered shrub: Eugenia is a large, worldwide genus of woody evergreen trees and shrubs of the myrtle family that is particularly diverse in South America, New Caledonia and Madagascar. The new species E. petrikensis is a shrub growing to two meters with emerald green, slightly glossy foliage and beautiful, dense clusters of small magenta flowers. It is one of seven new species described from the littoral forest of eastern Madagascar and is considered to be an endangered species. It is the latest evidence of the unique and numerous species found in this specialized, humid forest that grows on sandy substrate within kilometers of the shoreline. Once forming a continuous band 1,600 kilometers long, the littoral forest has been reduced to isolated, vestigial fragments under pressure from human populations.
Lightning Roaches? 
Lucihormetica luckae 
Country: Ecuador
Glow-in-the-dark cockroach: Luminescence among terrestrial animals is rather rare and best known among several groups of beetles — fireflies and certain click beetles in particular — as well as cave-inhabiting fungus gnats. Since the first discovery of a luminescent cockroach in 1999, more than a dozen species have (pardon the pun) "come to light." All are rare, and interestingly, so far found only in remote areas far from light pollution. The latest addition to this growing list is L. luckae that may be endangered or possibly already extinct. This cockroach is known from a single specimen collected 70 years ago from an area heavily impacted by the eruption of the Tungurahua volcano. The species may be most remarkable because the size and placement of its lamps suggest that it is using light to mimic toxic luminescent click beetles.
No Social Butterfly 
Semachrysa jade 
Country: Malaysia
Social media lacewing: In a trend-setting collision of science and social media, Hock Ping Guek photographed a beautiful green lacewing with dark markings at the base of its wings in a park near Kuala Lumpur and shared his photo on Flickr. Shaun Winterton, an entomologist with the California Department of Food and Agriculture, serendipitously saw the image and recognized the insect as unusual. When Guek was able to collect a specimen, it was sent to Stephen Brooks at London's Natural History Museum who confirmed its new species status. The three joined forces and prepared a description using Google Docs. In this triumph for citizen science, talents from around the globe collaborated by using new media in making the discovery. The lacewing is not named for its color — rather for Winterton's daughter, Jade.
Hanging Around in the Jurassic 
Juracimbrophlebia ginkgofolia 
Country: China
Hangingfly fossil: Living species of hangingflies can be found, as the name suggests, hanging beneath foliage where they capture other insects as food. They are a lineage of scorpionflies characterized by their skinny bodies, two pairs of narrow wings, and long threadlike legs. A new fossil species, Juracimbrophlebia ginkgofolia, has been found along with preserved leaves of a gingko-like tree, Yimaia capituliformis, in Middle Jurassic deposits in the Jiulongshan Formation in China's Inner Mongolia. The two look so similar that they are easily confused in the field and represent a rare example of an insect mimicking a gymnosperm 165 million years ago, before an explosive radiation of flowering plants. Why create a top 10 new species list? Arizona State University's International Institute for Species Exploration announces the top 10 new species list each year as part of its public awareness campaign to bring attention to biodiversity and the field of taxonomy. "Sustainable biodiversity means assuring the survival of as many and as diverse species as possible so that ecosystems are resilient to whatever stresses they face in the future. Scientists will need access to as much evidence of evolutionary history as possible," said the institute's Wheeler, who is also a professor in ASU's School of Life Sciences in the College of Liberal Arts and Sciences, and in the School of Sustainability, as well as a senior sustainability scientist with the Global Institute of Sustainability. "All of our hopes and dreams for conservation hinge upon saving millions of species that we cannot recognize and know nothing about," Wheeler added. "No investment makes more sense than completing a simple inventory to the establish baseline data that tells us what kinds of plants and animals exist and where. Until we know what species already exist, it is folly to expect we will make the right decisions to assure the best possible outcome for the pending biodiversity crisis." Additionally, the announcement is made on or near May 23 to honor Linnaeus. Since he initiated the modern system for naming plants and animals, nearly two million species have been named, described and classified. Excluding unknown millions of microbes, scientists estimate there are between 10 and 12 million living species. IISE International Selection Committee: Antonio G.

Southampton Varsity: Antarctica's first whale skeleton found with nine new deep-sea species

Inside a Killer whale skeleton
London, Mar.20 (ANI): Marine biologists have, for the first time, found a whale skeleton on the ocean floor near Antarctica, giving new insights into life in the sea depths. The discovery was made almost a mile below the surface in an undersea crater and includes the find of at least nine new species of deep-sea organisms thriving on the bones. The research, involving the University of Southampton, Natural History Museum, British Antarctic Survey, National Oceanography Centre and Oxford University, is published online in Deep-Sea Research II: Topical Studies in Oceanography. "The planet's largest animals are also a part of the ecology of the very deep ocean, providing a rich habitat of food and shelter for deep sea animals for many years after their death," says Diva Amon, lead author of the paper and PhD student from the University of Southampton and the Natural History Museum. "Examining the remains of this southern Minke whale gives insight into how nutrients are recycled in the ocean, which may be a globally important process in our oceans," continues Diva, who is based in the Graduate School of the National Oceanography Centre, Southampton (GSNOCS). Worldwide, only six natural whale skeletons have ever been found on the seafloor. Scientists have previously studied whale carcasses, known as a 'whale fall', by sinking bones and whole carcasses. Despite large populations of whales in the Antarctic, whale falls have not been studied in this region until now. "At the moment, the only way to find a whale fall is to navigate right over one with an underwater vehicle," says co-author Dr Jon Copley at University of Southampton. Exploring an undersea crater near the South Sandwich Islands gave scientists just that chance encounter. "We were just finishing a dive with the UK's remotely operated vehicle, Isis, when we glimpsed a row of pale-coloured blocks in the distance, which turned out to be whale vertebrae on the seabed," continues Dr Copley. When a whale dies and sinks to the ocean floor, scavengers quickly strip its flesh. Over time, other organisms then colonise the skeleton and gradually use up its remaining nutrients. Bacteria break down the fats stored in whale bones, for example, and in turn provide food for other marine life. Other animals commonly known as zombie worms can also digest whale bone. "One of the great remaining mysteries of deep ocean biology is how these tiny invertebrates can spread between the isolated habitats these whale carcasses provide on the seafloor," says co-author Dr Adrian Glover at the Natural History Museum. "Our discovery fills important gaps in this knowledge." The team surveyed the whale skeleton using high-definition cameras to examine the deep-sea animals living on the bones and collected samples to analyse ashore. Researchers think that the skeleton may have been on the seafloor for several decades. Samples also revealed several new species of deep-sea creatures thriving on the whale's remains, including a 'bone-eating zombie worm' known as Osedax burrowing into the bones and a new species of isopod crustacean, similar to woodlice, crawling over the skeleton. There were also limpets identical to those living at nearby deep-sea volcanic vents.(ANI). Source: News Track IndiaImage: flickr.com
