Image guided lumbar nerve root sleeve injection

Anatomy of the lumbar spine

Prof Mark Khangure, Dr Jason Wenderoth, January 31, 2012, 1. What is a lumbar nerve root sleeve injection? The spine is made up of bones called vertebrae. Between each vertebra is a ‘disc’ that allows the spine to be flexible. In between adjacent vertebrae, there is an opening on each side called a ‘foramen’, through which a nerve exits on its way to the buttock or leg. The nerve is surrounded by a ‘sleeve of fat’. Injection of corticosteroid (or ‘steroid’) and/or a local anaesthetic in the fat surrounding the nerve root is called nerve root sleeve injection. Corticosteroid medication decreases inflammation in the nerve root and will often reduce pain caused by nerve root inflammation, irritation of the nerve caused by arthritis or conditions such as disc degeneration or prolapsed disc (where the disc bulges). 2. Why would my doctor refer me to have this procedure? Back and/or leg pain can come from compression of the nerve as it passes through the foramen. Compression can come from a damaged, bulging disc or from extra bone that grows as a response to arthritis in the joints between the vertebrae. Inflammation from scar tissue and swelling after surgery on the spine can also irritate the nerves in the lower back. An injection of corticosteroid around the nerve root may alleviate the pain by reducing inflammation of the nerve. If the pain is suspected to come from a particular root, but it is not certain which one (especially in older people who may have root compression as a result of arthritis at a number of spinal levels), blocking the root with anaesthetic confirms or rules out that particular root as the cause. This can help in planning for future surgery. If surgery is a consideration, root sleeve injection may be used to relieve the pain before the surgery and can sometimes allow surgery to be delayed or avoided. 3. How do I prepare for a lumbar nerve root sleeve injection? Because you will be lying on your stomach during the procedure and will be uncomfortable if your stomach is too full, it is advisable to limit food intake to a light meal only, up to 2 hours before the procedure. You should wear comfortable clothes that are easy to remove and leave jewellery at home. Please note that some of the disinfectant agents used during these procedures may stain light-coloured clothing. When you make your appointment for the lumbar nerve root sleeve injection, you need to let the radiology clinic or department know if you are taking any blood thinning medication, such as warfarin, clopidogrel, dabigatran, prasugrel, dipyridamole or asasantin (for more information about these medications, go to NPS: http://www.nps.org.au/medicines). Blood thinning medications may need to be stopped for a period of days, or your normal dose reduced, before this procedure is carried out. It is very important that you do not stop any of these medications or change the dose without consulting both the radiology clinic or department and your own doctor. They will give you specific instructions about when to stop and restart the medication. These drugs are usually prescribed to prevent stroke or heart attack so it is very important that you do not stop taking them without being instructed to do so by your doctor or the radiology practice, or both. Aspirin is usually not stopped. A blood test may be required to check your blood clotting on the day of the procedure. Continue with pain medication and other medications as usual. You may be monitored for 2–3 hours after the procedure, so please allow for this. You should arrange for someone to take you home after the procedure, as it is not advisable to drive for the rest of the day as you may have numbness, weakness or other temporary side-effects after the procedure. 4. What happens during a lumbar nerve root sleeve injection? You will be asked to change into a hospital gown in a changing room. You will be taken from the changing room into the computer tomography (CT) scanning room. You will be asked to lie on the CT scanning table on a thin plastic mattress. Plastic tape with small metal markers attached to it will be taped onto your back. The scanning table will be moved into the scanner and CT images or pictures of your spine will be taken. The tape with the markers is used to mark the spot, or level, in your spine where the needle for the lumbar nerve root sleeve injection will enter the skin. The spot will be marked on your skin with a pen and the tape removed. The skin on the back is cleaned with antiseptic, which is usually very cold. The area is then covered with a sterile drape. The radiologist (specialist doctor) or other specialist doctor carrying out the procedure will inject local anaesthetic into the skin and deeper tissues in your lower back. This will numb the skin and deeper tissues. This produces a pin prick and a stinging sensation that is uncomfortable for a few seconds. You will be awake and only the area where the lumbar nerve root sleeve injection is being carried out will be numb. When the skin and muscles are numb, a thin spinal needle is then guided into place. CT scanning will be used to guide this so the doctor can confirm accurate placement of the needle. When the needle is in the correct location, contrast medium (X-ray dye) may be injected to check the needle position. Contrast medium allows the X-ray to show the blood vessels more clearly on the images. A combination of corticosteroid and long-acting local anaesthetic is then injected into the tissue surrounding the nerve root. The placement of the needle and injection of contrast into the foramen may produce some discomfort if the foramen is very tight from disc problems or a bony spur compressing the nerve root. The long-acting local anaesthetic very rapidly numbs the nerve. The area of the limb supplied by the nerve being treated goes numb, and the leg or foot may feel ‘dead’ for a while. This can be worrying when it happens, but you should be aware that the feeling and movement will recover soon. 5. Are there any after effects of a lumbar nerve root sleeve injection? 

• The leg is usually numb for a period of time. If the anaesthetic spreads into the spinal canal, the opposite leg may also be numb for a period of time (minutes to 1–2 hours).
• There may be an increase in the leg pain when the injection starts, particularly if the root in the foramen is severely compressed. The pain eases off when the anaesthetic spreads around the compressed root. 

6. How long does a lumbar nerve root sleeve injection take? The actual procedure itself takes approximately 15 minutes. You may be monitored after the procedure for 2–3 hours, so please allow for this. Monitoring occurs after the procedure to make sure any numbness, weakness or other temporary side-effects of the procedure have worn off before you go home. You may also have your blood pressure and breathing monitored after the procedure. 7. What are the risks of a lumbar nerve root sleeve injection? 

• Direct injection into the nerve root, rather than around the root, can produce intense pain. Injection into the root could damage the nerve, resulting in loss of sensation and weakness of the muscle supplied by the nerve in question. Using CT scan images to guide the procedure minimises this risk. 
• Injection of the medication into a surrounding blood vessel may mean the procedure does not work, because the medication has been carried away in the bloodstream. 
• A nerve root sleeve cyst may appear like a disc fragment in the foramen and injecting this cyst can result in headache that lasts for a few days, but is relieved by lying down and taking simple analgesia, such as paracetamol. The leakage of fluid from the cyst is what causes the headache and when this leak seals off (usually after a day or two), the headache will go away. Lying flat in bed and taking plenty of fluids will help the headache and help the tiny leak to seal off more quickly than if you carry out your normal activities.
• Injection of medication into the fluid sac surrounding the spinal nerves can occur, which causes complete numbness of both legs immediately. 
• Arachnoiditis is an inflammation of the nerves within the fluid sac, and results in chronic back and lower limb pain.The long-term risk of arachnoiditis is a potential complication if particulate steroid is injected into the spinal fluid. Checking the needle position using CT scan images with contrast before injecting the corticosteroid to ensure that the needle tip is not in the spinal fluid helps to avoid this from happening. If there is any doubt about needle position, non-particulate water-soluble steroid is used. 
• Allergic reactions to the local anaesthetic and steroid medication are rare.
• Infection of the skin and deep tissues is possible, but is rare.
• Bleeding around the puncture site may compress the nerve root, causing short-term worsening of pain. The pain will decrease when the bleeding or bruise next to the nerve root goes away, but this can take a few days.

There are very few reports in the literature of permanent leg weakness and bladder function problems (paraplegia) after this procedure. This rare risk is thought to be caused by unintentional injection of one of the arteries that is a branch of an artery that supplies the spinal cord, and the use of particulate corticosteroids. It is thought that using non-particulate corticosteroids and checking that the needle is not in a vessel before injecting the steroid medication reduces or eliminates this complication. Overall, the risks are minimal when carried out by experienced specialist doctors using CT image guidance. Approximately 7 in every 1000 patients will have some type of complication from this procedure and the severe complications (such as permanent nerve root damage) are rare. 8. What are the benefits of a lumbar nerve root sleeve injection? The benefits of a lumbar nerve root sleeve injection include temporary or long-term relief of back and nerve root pain. Breaking the pain cycle aids in healing. Pain relief also makes you more comfortable, allowing the disc protrusion to shrink. This may delay or remove the need for surgery. 9. Who does the lumbar nerve root sleeve injection? Lumbar nerve root sleeve injections are usually carried out by radiologists. The doctor carrying out the procedure needs to be appropriately trained in carrying out procedures using CT imaging and experienced in carrying out this procedure. Sometimes the procedure is carried out by pain management specialists, usually using X-ray imaging. 10. Where is a lumbar nerve root sleeve injection done? The procedure is carried out in a radiology practice, a radiology department in a hospital, an operating theatre with CT and X-ray imaging or an angiography suite. Wherever the procedure is carried out, there is a requirement for post-procedure observation beds and nursing care in order to identify and treat any of the complications that can sometimes occur after the procedure. 11. When can I expect the results of my lumbar nerve root sleeve injection? The time that it takes your doctor to receive a written report on the test or procedure you have had will vary, depending on:

• the urgency with which the result is needed;
• the complexity of the examination;
• whether more information is needed from your doctor before the examination can be interpreted by the radiologist;
• whether you have had previous X-rays or other medical imaging that needs to be compared with this new test or procedure (this is commonly the case if you have a disease or condition that is being followed to assess your progress);
• how the report is conveyed from the practice or hospital to your doctor (in other words, email, fax or mail).

Please feel free to ask the private practice, clinic or hospital where you are having your procedure when your doctor is likely to have the written report. It is important that you discuss the results with the doctor who referred you, either in person or on the telephone, so that they can explain what the results mean for you. 12. Further information about lumbar nerve root sleeve injection. The procedure is effective if there is an accurate diagnosis as to the cause of the pain. If there is no nerve root compression or irritation at the level of the injection, there will be little or no response. Does the procedure need to be done under general anaesthesia? No. The most uncomfortable part of the procedure is the initial injection of local anaesthetic. After this, the rest of the procedure is usually not especially painful. Source: Inside Radiology

Look into mobile, get your eyes tested

Soon, your phone will have one more function - telling you whether you need glasses or not. A team headed by Indian-born researcher Ramesh Raskar at the Massachusetts Institute of Technology (MIT) has developed a software and a smartphone accessory that can perform eye tests and  save you a trip to the optometrist. "We have conducted scientific trials and hope to market the instrument in India in the next few months," Raskar, associate professor in media arts and sciences at MIT, told HT. The device called NETRA (Near Eye Tool for Refractive Assessment) can be clipped on to a mobile phone with a suitable hi-resolution LCD display. It can then detect whether you need glasses. The test takes less than a minute. Raskar explained that after attaching the device, those with perfect vision will see a single line, while shortsighted or longsighted people will see multiple or distorted lines. It will also help people figure out the power of the glasses they need. "Eyecare is a low priority area in India. Eyeglasses can help almost 300 million people," Raskar said. Source: Hindustan Times, Image: flickr.com

When doing favors, monkeys don't keep score

Humans may not be unique in the ability to assist strangers.

By: By Lisa Newbern, While exchanging favors with others, humans tend to think in terms of tit-for-tat, an assumption easily extended to other animals. As a result, reciprocity is often viewed as a cognitive feat requiring memory, perhaps even calculation. But what if the process is simpler, not only in other animals but in humans as well? Researchers at Emory’s Yerkes National Primate Research Centerhave determined monkeys may gain the advantages of reciprocal exchange of favors without necessarily keeping precise track of past favors. Malini Suchak, an Emory graduate student, and psychologistFrans de Waal, director of the Living Links Center at Yerkes, led the study. Their findings will appear online in the Proceedings of the National Academy of Sciences this week. "Prosocial is defined as a motivation to assist others regardless of benefits for self,” Suchak explained. "We used a prosocial choice test to study whether direct reciprocity could promote generosity among brown capuchin monkeys. We found one monkey willing to do another favors if the first monkey was the only one to choose, and we found the monkeys became even more prosocial if they could alternate and help each other. We did not find any evidence that the monkeys paid close attention to each other's past choices, so they were prosocial regardless of what their partner had just done.” Suchak and de Waal suggest the synchronization of the same actions in alternation creates a more positive attitude the same way humans who row a boat together or work toward a shared goal develop a more positive attitude about each other. The capuchin monkeys were prosocial whether they were paired with a familiar partner from their own group or a partner from a different social group. "This research has several implications for better understanding human behavior,” de Waal said. “First, we observed an increase in prosocial behavior as a result of reciprocity, but the monkeys did not develop a contingency between their own and their partners' behaviors. Like humans, the capuchins may have understood the benefits of reciprocity and used this understanding to maximize their own benefits. Second, that the capuchins responded similarly to in-group and out-group partners has implications for the commonly held view that humans are unique in their ability to cooperate with strangers.” The researchers tested 12 brown capuchin monkeys in pairs on a prosocial choice task. The monkeys had the choice between a selfish token that benefited only them and a prosocial token that benefited themselves and a partner. By comparing each monkey's behavior with a familiar partner from the monkey's own group and a partner from a different social group, the researchers examined the influence of each monkey's relationship outside the experimental context on prosocial behavior. There was no difference between in-group and out-group pairs in any of the test conditions. To test the role of reciprocity, the researchers allowed the monkeys to take turns making choices and found this greatly increased prosocial behavior, but the researchers did not observe any tit-for-tat behavior. The researchers also tested whether the monkeys could overcome their aversion for inequity by creating a situation in which both individuals could provide each other with superior rewards, making reciprocity an even more attractive strategy. The monkeys did, but again without keeping track of each other's choices. Finally, through a series of control conditions, the researchers established the monkeys were responding to their partners' behaviors, rather than the rewards delivered by their partners, and that the monkeys understood the values of the tokens and were flexibly responding to changing conditions throughout the test sessions. Source: eScienceCommons

Nanotechnology breakthrough could impact on life-like telepresense

Thomas is working with gold nanoparticles and studying their properties when they are shrunk into a small size regime called nanoclusters. Nanoparticles are already microscopic in size, and a nanometer is about 1/80000 of the thickness of a single strand of human hair. Nanoclusters are on the small end and nanocrystals are on the larger end of the nanoregime. Nano clusters are so small that the laws of physics that govern the world people touch and smell aren’t often observed. Thomas and his team found that nanoclusters developed by adding atoms in a sequential manner could provide interesting optical properties. It turns out that the gold nanoclusters exhibit qualities that may make them suitable for creating surfaces that would diffuse laser beams of high energy. Apart from applications in defense in protecting pilots from laser beams, Thomas also thinks that these nanoclusters could improve the sensitivity of semi-relfective films to light. This could lead to Pepper’s Ghost style solutions which require much less of a controlled lighting environment to create the illusion and make them considerably more practical in the installed environment rather than just as stage gimmicks for rock stars and CEOs. Source: InAVate

Innovation" is the key word in scientific achievement

"How curiosity begat Curiosity" Scientific breakthroughs come from investing in science education and basic research. By: Ahmed Zewail, August 19th, 2012, Los Angeles Times

On Aug. 5, I was among those who witnessed the rover Curiosity landing on Mars in real time at NASA's Caltech-managed Jet Propulsion Laboratory. The excitement was overwhelming: The one-ton Mars Science Laboratory broke through the Red Planet's atmosphere, slowed its speed from 13,000 mph to almost zero and touched down. One glimpse of those first images from more than 100 million miles away demonstrated America's leadership in innovation. Curiosity — the rover and the concept — is what science is all about: the quest to reveal the unknown. America's past investment in basic science and engineering, and its skill at nurturing the quest, is what led to the Mars triumph, and it is what undergirds U.S. leadership in today's world. But now, decreases in science funding and increases in its bureaucracy threaten that leadership position. After World War II, scientific research in the U.S. was well supported. In the 1960s, when I came to America, the sky was the limit, and this conducive atmosphere enabled many of us to pursue esoteric research that resulted in breakthroughs and Nobel prizes. American universities were magnets to young scientists and engineers from around the globe. The truth is that no one knew then what the effect of that research would be; no one could have predicted and promised all that resulted. After all, it is unpredictability that is the fabric of discovery. In much of academia today, however, curiosity-driven research is no longer looked on favorably. Research proposals must specifically address the work's "broad relevance to society" and provide "transformative solutions" even before research begins. Professors are writing more proposals chasing less research money, which reduces the time available for creative thinking. And with universities facing rising costs generally, professors are more and more involved in commercial enterprises, which may not always push basic research forward. Even faculty tenure may be driven less by how good one is at science than how good one is at fundraising. These constraints and practices raise the question: Would a young Albert Einstein, Richard Feynman or Linus Pauling be attracted to science today? Would they be able to pursue their inquiries into fundamental questions? A generation ago, at the same time that government was supporting curiosity-based research, so was U.S. industry. One of the jewels was Bell Labs, where fundamental research was so advanced that it used to be said that it was "the best university in America." Bell Labs employed some of the world's leading scientists and engineers, and collectively they made pioneering contributions, from the discovery of the tiny transistor to the "big bang" origin of our universe. The broad-based fundamental research at Bell Labs is no longer pursued, and other industrial labs have, for the most part, disappeared or redirected their resources into much more product-oriented research. I teach at Caltech and oversee a research laboratory there. In general, I find that the majority of young people are excited by the prospects of research, but they soon discover that in the current market, many doctorate-level scientists are holding temporary positions or are unemployed. The average age at which principal investigators receive their first major government grant has risen, and experience from multiple postdoctoral positions is often necessary for advancement in academia. This slow track discourages young scientists from pursuing research careers. So what is the formula for better "managing" discoveries? The answer is in the natural evolution of research and development, from curiosity-driven science to technology transfer and then to societal benefits. We must nurture creative scientists in an environment that encourages interactions and collaborations across different fields, and support research free from weighty bureaucracies. The nation must provide young people with a proper and attractive education in science, technology, engineering and math. And the best minds from around the world should be encouraged, not discouraged, by public policy to join in this American endeavor. In sum, a renewed vision for investment in fundamental research is needed, especially in Washington, where further cuts across the board in science funding are being contemplated. In the 1950s, Nobel laureate Robert Solow showed that new technologies create a large portion of economic growth, affecting nearly 75% of the growth output in the U.S. The theory of quantum mechanics alone has had a major impact. Without it, revolutionary technologies would not have been realized. Think of the laser, optical communications, MRI and discoveries in drug design, gene technology and miniaturization. At the same time, American influence in the world is bolstered largely through its "soft" power, and science and technology is an essential force of this influence, according to the Pew Research Center's Global Attitudes Project poll. Since the Industrial Revolution, the West has dominated world politics and economics with the power of science. Since the mid-20th century, the United States has been at the center of that dominance, and more recently, China is pouring resources into R&D to reach first world status. The U.S. can still maintain research institutions, such as Caltech, that are the envy of the world, yet it would be hubristic and naive to think that this position is sustainable without investing in science education and basic research. We do not know now what will be relevant tomorrow. American innovation and leadership put the rover Curiosity on Mars. Now is the time to recommit to the wise vision that made it happen — otherwise the sun of innovation will come from the east. [Ahmed Zewail, winner of the 1999 Nobel Prize in chemistry, is a professor of chemistry and physics at Caltech.

Now Control Your Car With A Wink or Nod

How about a car that works at your nod and wink? Engineers have come up with a whole new way driving using just facial expressions after creating a gadget that controls a car's functions using nods and winks. The infra-red sensor is mounted on the dash board and recognises the driver's facial expression to control the car. A computer concealed inside the car translates the gestures which corresponds to a list of commands for the radio, Sat Nav, heating and mobile phone. The gestures, which are being tested before they are finalised, include a wink to turn the radio and music player on and off. The technology is meant to be able to differentiate between an accidental blink and a wink by the length of time of the action before turning the radio on or off. Drivers can nod left to turn the volume up and right to turn it down while a tap on the steering wheel to skip the station or song. Motorists can even make a phone call by making
the 'lifting the receiver gesture' with their hand and dial by saying the name of the person they wish call. Motorists can even control the air conditioning and heating by raising and lowering their left hand above the gear stick which has another computer sensor mounted inside. The technology means drivers would be able to control the functions inside the car without being distracted from the road. Engineers from global infotainment specialists Harman have created a prototype car which could hit the roads in two years time.Hans Roth, director of technology at Harman, said: 'It’s all about reducing distractions in the car. If you don’t have to take your hands off the wheel or look down then it’s obviously safer. We are still testing a list of gestures which could be standard for all cars across the world.' CAR CONTROL GESTURES: These basic gestures are being testing around the globe to find the ideal system that can be used in countries around the world: 1.Wink - To turn the radio on and off. 2. Nod left - Turn the volume up., 3. Nod right - Turn the volume down., 4. Tap finger on steering wheel - Skip radio channel or song. 5. Left hand up (above gear stick) - Turn the heating on.6. Left hand down (above gear stick) - Turn the air-conditioning on. Phone gesture - To make a call. Source: Tech Guide

Solar-Powered Roads to Solve the Problem with Snow-Covered Highways

Places where people often witness an abundant amount of snow in winter face a serious problem linked with roads. Billions of dollars are spent each year to remove the snow and repair the roads damaged by the weather. In order to solve the problem, a researcher named Rajib Mallickproposed solar powered road systems. The systems would store the power of the sun to help clear streets and possibly provide an alternative source of electricity. Mallick's idea is to embed pavement with fluid-filled pipes. The fluid, which would be resistant to freezing, would be heated by the sun and stored in an insulated chamber. When ice and snow hit the roads, the heated fluid could be released to melt the snow. The heat from the fluid could also be used to provide electricity to nearby buildings. The project's cost is estimated at $12,500 for every 50 meters of pipe, plus annual maintenance costs of $1,000. But Mallick tells the system could pay for itself in six months while also providing enough electricity to heat 55 homes for one month a year. Source: Tech Guide

PAL-V One [Personal Air and Land Vehicle]

.

Tech Guide: PAL-V One - a hybrid vehicle that is also a gyroplane. The name of the two-seater car stands for "Personal Air and Land Vehicle" and it allows the driver to travel by road or air. Developed by the Dutch company, PAL-V, The car is very maneuverable and quick thanks to its three wheels and a special patented "tilting" system. In case the driver wants the car to take off, they should visit the nearest airport first and then, with the help of a single motor and propeller that opens out from the top of the vehicle, leave the ground. The transformation of the car into a gyroplane takes about 10 minutes. All that the driver has to do is just push a special button. "Personal Air and Land Vehicle" is allowed to reach an altitude below 4,000 feet, according to uncontrolled Visual Flight Rules (VFR) traffic. Due to the fact that the car boasts a short take off and landing capability, you can land it almost anywhere. The maximum speed that PAL-V One can reach is 112mph. While on the road, the hybrid vehicle can travel 750 miles using its gasoline engine. In the air the car can has a range of up to 315 miles. Although currently it is powered by gasoline, the developers look forward to making versions that run on biodiesel or bio-ethanol.Source: Tech Guide

Dolphin yoga: new relaxation technique or potential danger?

Intelligent, highly perceptive, and adorable – dolphins are one of the few animals that humans can sincerely say this about. The qualities that they have as a species are remarkable and their ability to pick up on new stimuli is fascinating. However, some scattered reports suggest they are, in fact, dangerous sea creatures.

By Sarah Neary, The practice of swimming with dolphins has been on the rise in recent years, but participants can’t just dive right in and mingle with the sea mammals. They are always supervised in the presence of a trainer. Since the dolphin doesn’t know the visitor in this scenario, these dolphins in captivity could retaliate out of fright. “They don’t cut your skin, they don’t draw blood, but they just give you a good strong pressure on the foot or on the leg with their teeth to let you know that they are not happy with the fact that they don’t recognize you,” said Larry Schaefer, who worked with dolphins at the Mirage for over two years as an educator and a VIP tour guide in the dolphin establishment. This type of behavior in dolphins is said to be perfectly natural. As well, more so than usual, people have good experiences in the water with these savvy swimmers. “The safety record of interactive programs offered by Alliance-accredited facilities is a phenomenal 99.99% safe because of the wonderful relationship our trainers have with the animals and their outstanding training of the dolphins,” said Marilee Menard, Executive Director of the Alliance of Marine Mammal Parks and Aquariums. The newest craze seems to be combining yoga with dolphins. Specialized places especially for dolphins and aquariums devoted to such have latched onto the opportunity of reinforcing people’s peace of mind with yoga and strengthening it with the serenity of a dolphin to add to their guided pleasure. This is all through the help of a trainer, who walks each person through the process. “Our facilities have education programs prior to interactions with dolphins to assure that the guests behave properly with the animals,” said Menard. Though, it is not known if Alliance facilities have this yoga-dolphin occurrence going on at their centers now or in the future. Dolphin enthusiasts who may not have the cash on hand for this unique encounter should be forewarned. In accordance with the Marine Mammal Protection Act of 1972, feeding or even trying to feed a dolphin is a crime in US waters. “You have to remain at least 50 feet away from wild dolphins and you’re not allowed to approach them, attempt to feed them, or swim with them. You can be caught and it’s quite a fine,” said Schaefer. Why such harsh regulations are put in place is easy to see. If people continually feed a wild dolphin, especially a young one, they may lose the ability to hunt on their own, potentially causing them to starve to death. As it has been said time and time again that dolphins are not aggressive by nature, one report raises questions. According to the NOAA Fisheries Office of Protected Resources’ website, wild dolphins bit a woman. The woman had reportedly fed them and then jumped in the water. To make matters worse, she is not the only case. Dolphins under the correct amount of supervision, whether through swimming or a yoga-related activity, may behave a lot better than those in their natural habitat. However, the facts still remain. Staying a good distance away from wild animals, including dolphins, is wise, because we never know what they may be capable of.  Source: Voice of Russia

Mobile Phone Charger That Runs On Water

A Swedish company has invented a charger for mobile phones, cameras and GPS devices that can power-up your electronic gadgets with little more than water. The PowerTrekk has been designed for people who 'who spend time away from the electricity grid' and do not have access to conventional power in remote locations. The charger needs just a tablespoon of water to produce around 10 hours of phone

battery life. The invention works with any device that has a USB port and with almostany type of water, including salt water. It can even run on puddle water providing it isn't thickened with mud or any other sediment. "PowerTrekk has a competitive edge over traditional portable chargers" said Björn Westerholm of myFC, the company behind PowerTrekk. Fuel cell power is generated immediately and charging is not impacted by weather or the position of the sun, as for solar panels. Compared to battery powered travel chargers, PowerTrekk offers reliable charging as the fuel packs do not deplete as batteries do. 

The process is easy for users. The sodium is stored in a small round container called a PowerPukk. The PowerPukk slots into one half of an outer container. In the other half is a tiny water tank, into which you pour the water. Once the lid is sealed on the outer container the chemical reaction begins automatically and the PowerTrekk is ready to use. The chemistry process is said to besafe and eco-friendly, and the only by-product is a little water vapor. Source: Tech Guide

Technology That Allows You To Control Your Laptop

You know that you can control your laptop with your mouse, trackpad, and keyboard-and you may even know that you can control your laptop with your voice, and maybe elaborate gestures thanks to motion-tracking devices such as Microsoft's Kinect. But did you know that you can also control your laptop with your eyes? Sweden-based Tobii Technology has developed eye-tracking technology that allows you to control your laptop and other devices using only your eyes. All you have to do is sit down in front of the computer. Tobii is built into the laptop, which is made by Lenovo, and is located below the screen. It works by shooting infrared lights into your eyes to cause red-eye which sounds dangerous, but they assure it's perfectly safe. By doing this, Tobii is able to create a 3D model of your eyeball and determine where your eye is relative to space. It then tracks the glint off of your eyeball to determine where your foveal vision, or sharp central vision, is, and, consequently, where you're looking. Initially there's some calibration, but it's pretty quick and easy. All you have to do is sit down in front of the computer and follow the flashing dots on the screen with your eyes-there are about five in total. This is a one time calibration, as once you've calibrated it the computer knows where your eyes are. Once the calibration is finished which takes about thirty seconds, you can start eye-controlling your device right away. There are a couple of other uses for Tobii technology. For example, the technology can track your eye movement when you're reading a document and automatically scroll down when you reach the end of the page. Also, the technology allows you to zoom into a particular area of the screen just by looking at that part of the screen and using your mouse's scroll wheel. However, Tobii technology is not a replacement for your mouse or your keyboard, since you can't blink to click or anything cool like that, it's just an additional way to interact with your device.Source: Tech Guide

Gadgets real and virtual

By Hassan M. Kamal : The Project Glass by Google has once again given a glimpse of how short the distance between the real and the virtual world is. The Augmented Reality (AR) based glasses released on Wednesday can take photos, give voice commands and receive information like directions, weather etc., all in real time, by sensing the real environment. All this is too futuristic to be available any time soon, but surprising as it is, Indians are already using several such AR-based applications. AR browsers like Layar, Guino and Wikitude are already popular among smartphone users in India. From finding restaurants, new offers and sales, driving directions, weather updates, to latest tweets about a restaurant’s food, the smartphone users are already making the most of the augmented real world to search information. The information is not just limited to text, users can also watch videos, pictures almost everything that is there on the Web, all that by just pointing the camera towards it. “Augmented reality is a technology that combines the real and virtual world together. The Western countries have been using it for quite some time, but Indians are not behind either,” says Gaurav of Gamooz, an augmented reality developing company in India. Gamooz has developed several AR worlds like one for New Delhi Metro Rail, which helps one find train timings etc., Eventbrite Finder, which tells one of nearby events and My Property Finder for Layar that gives details about rents, flats on sell among others. A Hyderabad-based company developed a system that enables shoppers to try apparels virtually on a fixed screen.A mobilephone version of this is expected soon. “Just select the dress and you could see an image of you on a screen wearing the apparel. But that’s not it, if you are still confused about the dress, you can share a picture on Twitter or Facebook and ask your friends for suggestion,” says Hemnath Satyanarayana, who developed the system. The system that comes for anything around Rs 5 lakh, would be available in by the end of 2012. While geo-location based services like these are becoming popular the technology has several other uses. For example if you lost your car in the parking lot, Car Finder will help you get it back. All you got to do is point your phone’s camera towards the parking lot. Even in gaming, with Kinect for XBox, the distance between virtual and real has blurred even further. The camera recognises the hand movements and instructs the animated character on the screen to move accordingly. “The player himself becomes the controller,” says Aditya Sen, a gaming expert. Aditya adds that Playstation Vita, which is expected to be launched soon also has a lot of augmented reality-based applications. Source: Deccan Chronicle
