New Delhi, As tuberculosis (TB) continues as the deadliest infectious cause of deaths globally, a new study has shown that artificial intelligence (AI)-enabled digital stethoscopes can help fill critical screening gaps, especially in hard-to-reach areas.

In a commentary published in the journal Med (Cell Press), global experts contended that stethoscopes combined with digital technology and AI can be a better option against the challenges faced in screening programmes, such as under-detection, high cost, and inequitable access.

“AI-enabled digital stethoscopes have demonstrated promising accuracy and feasibility for detecting lung and cardiovascular abnormalities, with promising results in early TB studies. Training and validation in diverse, high-burden settings are essential to explore the potential of this tool further,” said corresponding author Madhukar Pai from McGill University, Canada, along with researchers from the UAE, Germany, and Switzerland.

Despite advancements in screening and diagnostic tools, an estimated 2.7 million people with TB were missed by current screening programmes, as per data from the World Health Organization (WHO). Routine symptom screening is also likely to miss people with asymptomatic or subclinical TB.

While the WHO recently recommended several AI-powered computer-aided detection (CAD) software, as well as ultra-portable radiography hardware, higher operating costs and upfront hardware act as a deterrent.

This particularly appeared difficult in primary care settings and or among pregnant women due to radiation concerns.

At the same time, AI showed significant potential for screening, including applications beyond CAD of TB from radiographs, said the researchers.

“One application of AI for disease screening is to interpret acoustic (sound) biomarkers of disease, with potential to identify sounds that appear nonspecific or are inaudible to the human ear,” they added, while highlighting the potential of AI in detecting and interpreting cough biomarkers and lung auscultation to analyse breath sounds.

Studies from high-TB burden countries, including India, Peru, South Africa, Uganda, and Vietnam, highlighted that AI-enabled auscultation could hold promise as a TB screening and triage tool.

"AI digital stethoscopes may become useful alternatives to imaging-based approaches for TB screening, with the potential to democratise access to care for populations underserved by radiography," the researchers said."Importantly, AI digital stethoscopes offer a scalable, low-cost, and person-centered tool that could bring us closer to reaching TB case finding goals," they added.

Spectacular New Species Found in Cambodia’s Limestone Caves–Asia's 'Little Laboratories'

A breathtaking expedition high among limestone escarpments and deep in the cave systems they contain has revealed several new reptile species, including a dazzling pit viper you have to see to believe.

Exploring over 60 caves across 10 hills in the Battambang province, western Cambodia, the survey uncovered a treasure trove of extraordinary creatures besides, many found nowhere else on Earth.

The survey was led by Fauna & Flora International in collaboration with Cambodia’s Ministry of Environment and field experts. The team identified 6 new geckos, 2 micro-snails, and 2 millipedes in addition to the viper.

They also confirmed the presence of many threatened species in the landscape surrounding the caves—such as the Sunda pangolin, Indochinese silvered langur, long-tailed macaque, and green peafowl, further highlighting the critical need to protect this habitat.

Karst covers 20% of the Earth’s landscape. This soluble bedrock made of limestone has created some of the most spectacular rocky landscapes on Earth—including the upturned egg cartons shapes along the great South China Karst, Ha Long Bay in Vietnam, Tsingy de Bemaraha in Madagascar, The Burren in western Ireland, the world’s largest wellspring in Vrelo Bune, Bosnia, the Cenotes of the Yucatan, in Mexico, and Mammoth Cave in the US.

The susceptibility of karst to erode from rainfall has seen it carved into a million beautiful and dramatic shapes that often play host to microclimates where threatened animals can thrive.

Dr. Lee Grismer, a professor of biology at La Sierra University in the US, was part of the expeditionary team, and spoke to F&F about the importance and uniqueness of the landscape.

“Each one of these isolated karst areas act as their own little laboratory where nature is performing the same experiment over and over and over independently. The results are species that exist nowhere else—not just nowhere else in the world, or that country—but in no other cave.”

Indeed, caves from easily in karst landscapes, and many of the world’s longest and largest—and least-explored—cave systems are found in East and Southeast Asia.

This is certainly the case in Battambang, where the survey team had first to ascend the steep forested slopes of the karst outcrops before scrambling and squeezing through crevices and crawlspaces to reach the cave systems.

Inside, they documented a rich array of life, both endemic to the caves and others—like a big reticulated python—who were just visiting. While the chatter of the Endangered silvered langur troupe, faded behind them, the team began encountering animal after animal that had never been described by science.

A spectacular new species of pit viper (from the Trimeresurus genus) was collected during the survey and is currently being described. Recognized by their triangular heads, these highly venomous snakes track down their warm-blooded prey using the heat-sensitive pits behind their nostrils.

4 populations of the striped Kamping Poi bent-toed gecko were found and identified as a new species: Cyrtodactylus kampingpoiensis. Despite being described as just one species, it is thought that, due to the geographic isolation of the karst formations, these 4 populations are on separate evolutionary trajectories, and further genetic analyses may reveal whether they are in fact 4 different species instead of 1.

Another new species of gecko was named after the Hindu god of destruction: Shiva.

In a statement, Fauna & Flora International said it is working with local partners to help conserve Cambodia’s karst landscapes, epitomized through the recent release of guidelines for sustainable development and management of cave ecosystems.

The guidelines integrate international best practices with Cambodian context, providing practical measures to safeguard bat colonies, preserve rare and endemic cave biodiversity, promote sustainable guano harvesting and ensure responsible tourism development.

“Cambodia’s karst areas are a treasure trove of scientific secrets waiting to be uncovered,” said Sothearen Thi, Karst Biodiversity Coordinator at Fauna & Flora in the statement.“But, without sustainable management, we may never find out what these areas truly hold. Karst landscapes are facing many human-driven challenges, and biologically significant species could go extinct before they have even been discovered. We are working with the Cambodian government and local partners to increase protection of the landscapes, with sustainable management being the number one priority.” Spectacular New Species Found in Cambodia’s Limestone Caves–Asia's 'Little Laboratories'

First Quantum Battery Prototype Marks Big Step for Technology Expected to Change the World

The prototype quantum battery – credit, CSIRO

Australian researchers have developed and tested the world’s first quantum battery.

Their prototype is far from anything that will be a perspective power source in an EV or storage facility, but the experiment revealed some important directions for future research.

A theoretical concept since 2013, the prototype was charged wirelessly with a laser, one of the special properties that quantum mechanics in battery technology promises if it can be properly understood and harnessed.

Lead researcher Dr. James Quach of CSIRO, Australia’s national science agency which led the study on the device, said it’s the first quantum battery ever made that performs a full charge-discharge cycle.

Dr. Quach explained that in society today, the larger the battery, the longer the charge time.

“That’s why your mobile phone takes about 30 minutes to charge and your electric car takes overnight to charge,” he said, adding that in contrast, “quantum batteries have this really peculiar property where the larger they are, the less time they take to charge.”

Less time really is an almost worthless descriptor in this case, because the prototype created by CSIRO was fully charged within a few quadrillionths of a second.

The problem is that the discharge rate was a few nanoseconds, which despite being 6 orders of magnitude longer, could be of no use to anyone now. Quach provided some interesting relative comparisons to help mere mortals conceptualize why this could be a world-changing innovation if improved.

If it takes 30 minutes to fully charge a mobile phone, and it too had a discharge rate equal to 6 orders of magnitude, that means it wouldn’t need to be recharged even after a decade of use.

“What we need to do next is… to increase the storage time,” Quach said, touching on this point. “You want your battery to hold charge longer than a few nanoseconds if you want to be able to talk to someone on a mobile phone.”

Additionally, the prototype doesn’t hold enough voltage to power anything substantial.

While this might all sound rather pointless, another, non-involved expert in the development of quantum batteries, University of Queensland Professor Andrew White, told the Guardian that the experiment was a huge success in getting the technology off the drawing board and into the real world for the first time.People would be far more likely to adopt EVs if they could be fully-charged in few seconds, even if their range was severely reduced.

Endangered Cahow, One of the Rarest Seabirds in the World, Hatched on Nonsuch Island in Bermuda

Though an event neither singular nor inaugural, the hatching of an endangered seabird and national icon of Bermuda is still being celebrated wildly by a special group of conservationists who’ve created a “living museum” on Nonsuch Island.

Measuring just 14 acres and found in the northeast corner of the Bermuda island chain, Nonsuch Island is the only place the world’s 3rd-rarest seabird, known locally as the cahow, comes to breed.

The fact that it is breeding at all is nearly a miracle, as the cahow was believed to be extinct for a period of 300 years that started in the early days of British colonial governance and extended all the way to the second-half of the 20th century.

The animal, also known as a Bermuda, or gadfly petrel, bears all the quirks of an animal doomed to follow the dodo into history. It takes 3-6 years for adults to return to Nonsuch Island to breed, and if they do, the female may produce one egg.

That one egg may hatch, although it might not; some 50% of the eggs don’t hatch. Adults abandon that single chick one-week before it fledges, when instinct drives it to seek food out at sea while still learning how to fly. Between 28 and 35% of fledglings don’t survive their first year.

Nesting on the ground, they’re extremely vulnerable to predation from invasive animals, and in 1960, British ornithologist and Bermuda’s first conservation officer, David Wingate, identified just 18 breeding pairs on Nonsuch Island.

Wingate would go on to pioneer the Cahow Recovery Program, which today is recognized as one of the most successful restoration projects anywhere in the world for a Critically-Endangered species.

By the time Wingate’s successor as chief of the program, Jeremy Madeiros, took over, their numbers had grown to 55. Today, there are 450 birds of all ages on the island, a remarkable turnaround.

Part of that turnaround was making sure these birds had good nesting habitat. Cahows nest in underground burrows or deep rock crevices; only nests deep enough to be completely dark are chosen.

Today, 85% of all cahows nest in artificial concrete nest burrows constructed for them as part of the Recovery Program.

The recovery program gestated a transformation of Nonsuch Island into a complete wildlife sanctuary, wooded, and with a small freshwater marsh where access to the public is strictly limited to prevent invasive species introduction. The restoration of the once barren island into a ‘Living Museum of pre-colonial Bermuda’ was Wingate’s life’s work.

65 years into this rewilding experiment, key endemics have repopulated the island, including the yellow-crowned night heron, West Indian top shell, land hermit crabs, and the beautiful Bermuda skink.Expeditions there are organized by the environment ministry for educational and research purposes, while several live camera feeds allow those interested to observe the cahow in its natural habitat.

India launches world’s 1st clinical trial to test Ayurveda with TB treatment

(File Photo/IANS)

New Delhi, (IANS) On the occasion of World Tuberculosis Day, India announced the world’s first clinical study to scientifically evaluate Ayurveda as an adjunct to standard Anti-Tuberculosis Treatment (ATT), the government said on Tuesday.

The collaborative clinical study between the Department of Biotechnology and the Ministry of Ayush will enrol 1,250 newly diagnosed tuberculosis patients across eight institutions to evaluate Ayurveda as an adjunct to standard treatment, focusing on body weight, nutritional outcomes, disease progression, quality of life, safety, and tolerability.

Union MoS for Science & Technology Jitendra Singh said the study reflects the spirit of “whole-of-science,” approach by integrating biotechnology and Ayurveda; “whole-of-government” approach through collaboration between ministries.

DG, CCRAS, Prof. Vaidya Rabinarayan Acharya said the initiative has progressed through consultations, protocol finalisation, and approvals.

Director, BRIC-NII, Dr. Debasisa Mohanty said the study will examine tuberculosis-associated cachexia as an immune-metabolic condition, using advanced tools such as DEXA, MRI, immune profiling, metabolomics, and single-cell RNA sequencing to understand changes in body composition, immune function, and energy metabolism.

It is aimed to assess how integrative interventions influence recovery and long-term outcomes, the statement from the Ministry of Science & Technology said.

Minister Jitendra Singh said India, which accounts for nearly 25 per cent of the global TB burden, saw a 21 per cent drop in a decade in tuberculosis incidence to about 187 cases per 1,00,000 population in 2024.

“The decline in TB incidence is an outcome of India’s dedicated and innovative efforts. Through a collective spirit, we will keep working towards a TB-free India,” he quoted Prime Minister Narendra Modi.

India has adopted an ambitious and accelerated pathway towards TB elimination, strengthening early diagnosis, universal drug susceptibility testing, digital adherence technologies, and patient-centric care under the National TB Elimination Programme, the minister said.

He pointed out the reciprocal relationship between TB and conditions such as diabetes, where each can aggravate the other, making integrated approaches essential for effective disease management.He also referred to the RePORT India programme, one of the largest TB research consortia, with over 4,500 enrolled TB patients and over 5,000 household contacts, generating evidence relevant for global policy frameworks, including WHO guidelines on nutrition and tuberculosis.

Scientists Were Wrong About How Fast Solar Panels Degrade – They May Last Twice as Long

A huge scientific survey of over 1 million German solar installations has revealed a surprising statistic: their potential to degrade year by year has been significantly exaggerated.

Previous models have overestimated the rate of degradation in a solar installation’s ability to generate power by between 20% to 50% according to this new survey.

“Back of the envelope,” the authors admit, “the estimated cost of degradation would decrease, compared to previous findings, by about €638 million per year to maintain installed capacity in 2040.”

Germany has been steaming forward with green energy installation for 20 years. Having decommissioned many of its coal power plants, and controversially eliminated its entire nuclear fleet as well, the country has installed some 60 gigawatts just of solar capacity since 2006.

A common criticism of solar is that photovoltaic panels—like all electrical hardware—lose efficiency over time, and, being exposed to the elements 365 days a year, frost, heat, wind, and dust beat them down such that the power you expected to receive when you built the solar installation isn’t what you are receiving a decade after.

The survey, conducted by scientists from Brandenburg University of Technology alongside a collaborator from University College London, involved around 1.25 million large and small solar installations across Germany, totaling 34 gigawatts of capacity. At 16 years, the study period was longer than any other examination, while the study period accounted for newer generations of solar panels.

The authors found annual degradation rates of 0.52–0.61%, roughly half the average reported in prior studies, which also had limitations of smaller sample sizes (the largest other survey of this kind was with 4,200 installations) and shorter study durations averaging between 2 and 7 years.

Other key findings support the value of large-scale solar installations. Degradation rates slow as the PV panels age. In other words, new PV panels lose capacity faster than older ones. Additionally, larger installations like solar farms degrade slower than smaller ones like rooftop arrays.

“That is important because it suggests that utility-scale PV cannot simply be treated as a scaled-up version of rooftop solar,” said lead author Peitro Melo, speaking with PV Magazine. “Reliability and maintenance strategies have a measurably different impact on outcomes.”

Frost, extreme heat, and air pollution affect PV panels differently at different stages of their lifespan. Extreme heat tends to reduce the efficiency of older panels more than newer ones, even though for frost and air pollution, it’s the opposite.

“This is a positive result for the solar industry, from households who have bought systems up to investors in megaprojects. Lower degradation means greater output and revenue over a project’s lifetime.”

Another way to summarize the team’s findings is that this new and more accurately-estimated degradation rate for PV systems translates to a 4.8% reduction in the levelized cost of electricity from solar panels. This means that, in order to maintain nameplate power production across the entire German fleet, 2.3 gigawatts of PV panels would have to be installed every year, while under previous assumptions, replacement rates have reached as high as 4.5 gigawatts.

24 New Species Including a New Family of Amphipods Identified in Deep Sea Survey

A recent international survey of a deep sea zone near Mexico turned up 24 species of shrimp-like animals called amphipods, including a whole new taxonomic family, called Mirabestiidae.

The survey took place in the Clarion-Clipperton Zone (CCZ) between Hawaii and Mexico, where a fractious seabed can range in depth from 10,000 to 20,000 feet.

Over 10,000 species of amphipods have been described by science, yet they’re such a diverse order of animals, an expedition such as this can still scoop out handfuls of new ones—and in all different colors too.

“To find a new superfamily is incredibly exciting, and very rarely happens so this is a discovery we will all remember,” said Dr. Tammy Horton of the UK’s National Oceanographic Center (NOC) in Southampton.

“With more than 90% of species in the CCZ still unnamed, each species described is a vital step towards improving our understanding of this fascinating ecosystem.”

The NOC was joined by partners and aspiring scientists from all across Europe, as well as New Zealand and Canada, for a weeks-long taxonomy workshop organized at the University of Lodz, Poland, led by Dr. Anna Jażdżewska.

The expedition and workshop were organized under the International Seabed Authority’s Sustainable Seabed Knowledge Initiative (SSKI) which aims to describe 1,000 new species by the end of the decade in order to possess a better understanding of deep-seabed biodiversity when making decisions about deep-sea mining.

“The team’s findings provide information that is crucial for future conservation and policy decisions, and it highlights how important it is for this work to continue,” Dr. Jażdżewska said in a statement.

Stretching 1.7 million square miles across the eastern Pacific Ocean, the CCZ was discovered by the Scripps Institution of Oceanography in 1954. It’s been an extremely well-surveyed area of the deep seabed, though that in itself isn’t saying much, and indeed 42% of all known deep sea species were first described in the CCZ.

The expedition uncovered a new family, called Mirabestiidae, and even a new superfamily Mirabestioidea, revealing completely new evolutionary branches. Two new genera were also discovered: Mirabestia and Pseudolepechinella.

For readers who lack a mental flowchart of taxonomy hierarchies, one famous family from above sea level is Felidae, containing all cats wild and domestic. Felidae is nested inside of the superorder Feliformia, which in addition to all the cats, contains civets, hyena, mongoose, and the curious fossa of Madagascar.

Two genera nested inside the family Felidae are Panthera, containing the tiger and the lion, and Lynx.

In the CCZ, students and professors alike reveled in pulling up one new species after another, before taking them back to a frigid Poland for analysis.Creatures were named in honor of both Horton and Jażdżewska, the organizers of the expedition and workshop, while others named species after relatives, impressions from the experience, and even a video game character that one of the amphipods resembled. 24 New Species Including a New Family of Amphipods Identified in Deep Sea Survey

How birds are spreading plastic pollution

Hungry gulls do not only steal our chips and sandwiches. They learn our habits, and look for reliable sources of food. That includes waste treatment centres, landfill or anywhere food waste is concentrated. Many gull populations have moved inland from the coast to exploit these sources of food.

Wherever our waste is processed, gulls and other birds can forage. At landfills, gulls feed on waste before it is covered up. If there are plastic or glass pieces covered in food that are small enough, gulls will swallow them whole. Only the food itself gets digested, and when the gull flies back to its roost site, the waste gets regurgitated, polluting that site. This movement of pollutants is known as “biovectoring”.

For the first time, scientists like me are now quantifying just how much plastic and other waste is being leaked into important nature areas through the daily movements of birds.

Many lesser black-backed gulls breeding in the UK and other parts of northern Europe migrate to Andalusia in southern Spain, where they form a wintering population of over 100,000 feeding mainly in rice fields and landfills. Fortunately, many of these birds are fitted with GPS tags while breeding. This enables detailed tracking of their movements.

Fuente de Piedra lake in Málaga is a hotspot for migrating lesser black-backed gulls. This wetland has such special natural significance, it’s designated as an internationally important site under a global convention known as Ramsar. It’s most famous for the largest breeding colony of flamingos in Spain. Gulls fly up to 50 miles to landfills to feed, then fly back to roost.

By combining GPS data with waterbird counts, and analyses of regurgitated pellets, scientists have estimated that an average of 400kg of plastics, plus more than two tonnes of other debris such as glass, textiles or ceramics, are deposited by this gull species into the lake each year. This lake has no outflow, making it salty and hence flamingo friendly. Those imported plastics remain in the lake, breaking down into microplastics. They can be ingested by flamingo chicks, aquatic insects and other animals.

In coastal Andalusia, these gulls join the resident yellow-legged gulls (equivalent to our herring gulls) and a mixture of migratory and resident white storks as the three major waterbird visitors to landfills.

In the Cádiz Bay wetlands (another Ramsar site), surrounding the historical city that is now a favourite stop for cruise ships, the three species combine to spread different types and sizes of plastics into different microhabitats. Annually, 530kg of plastics are deposited into wetlands via regurgitated pellets. Although a stork is bigger, so transports more waste per bird, most of the plastic is again moved by the lesser black-backed gulls that winter there in larger numbers.

This waste ingestion has strong effects on the birds themselves, through direct mortality from diseases, choking or becoming entangled with plastics, and toxic effects of the additives within them. Then after regurgitation in pellets, those plastics are a threat to all fauna and readily enter our food supply through aquaculture and table salt production, both important in Cádiz Bay.

These studies in Spain address a problem that is ongoing all over Europe. There are no comparable quantitative studies yet in the UK, but similar problems occur wherever gulls concentrate to feed on our waste. If white storks become abundant in the UK future, they will probably visit our landfills, together with gulls and perhaps cattle egrets.

The sealing of many landfills, and improvements in waste management may have contributed to recent declines in many gull populations in the UK and elsewhere. But these problems of plastic leakage will continue so long as our consumer society generates so much waste. Reducing waste, and reusing things is better than recycling, partly because food containers may get eaten by birds before they can be recycled. Cleaning our food containers before we bin them, and composting our own food waste, can also help to reduce this phenomenon.

Australia has dedicated more than 20% of its land to conservation but not where it matters most

On paper, Australia is a conservation success story.

Over the past 15 years, we’ve dedicated vast areas of land to conservation. Our primary goal has been to protect our unique plants, animals, and ecosystems. As a result, Australia now has one of the largest protected area estates in the world, covering roughly 22% of the country.

That’s an impressive achievement, and a significant step towards our goal of protecting 30% of Australia’s land by 2030.

But there’s a problem. Our new analysis shows we’re not protecting the places that matter most for Australia’s diverse wildlife and environments.

So what are we actually conserving? And what should change?

More land but no more protection

Our recent analysis of Australia’s network of protected areas shows, between 2010 and 2022, we’ve nearly doubled the amount of land under protection. Protected land refers to areas which are specifically set aside to conserve nature. However, this expansion has done little to help our most at-risk animals, plants, and ecosystems.

Our national list of threatened species, which identifies the plants and animals most at risk of extinction, illustrates this. Since 2010, we’ve only slightly increased the amount of protected land that’s home to threatened species. Based on our data, in that time this figure rose by an average of just 3%.

Worse still, 160 species have virtually no protection. That’s roughly 10% of our endangered species list. Many others species only have a very small amount of their habitat inside the fences of protected areas.

One example is the Margaret River burrowing crayfish, a critically endangered crayfish from Western Australia. Currently none of its two remaining habitats are protected.

And the Grey Range thick-billed grasswren, a bird endemic to New South Wales, is now critically endangered because of habitat loss and agriculture. However none of its habitat, found just north of Broken Hill, is formally protected.

Tragically, these are not exceptional cases. And they are exactly the plants and animals that protected areas are designed to protect.

The same is true for Australia’s ecosystems, which are geographic areas where plants and animals interact with their natural environment. Nationally, we have nearly 100 ecological communities which are listed as threatened. But in the last decade, we’ve only improved protection for a handful of these.

And some still have no protection. The critically endangered weeping myall woodlands in the Hunter Valley, Sydney’s blue gum high forest and the iron-grass natural temperate grassland of South Australia are just three examples.

So what’s gone wrong?

For decades, we’ve tended to protect land that is more remote and less productive. Our findings suggest this pattern is continuing today.

However, many of Australia’s at-risk plants, animals, and ecosystems are found in heavily modified landscapes. These include areas which have been cleared for agriculture or are close to towns and cities. But under current conservation models, we’re much less likely to protect these kinds of land.

As a result, we are expanding protected areas but not necessarily where they matter most.

Protected areas, such as Kakadu National Park, help safeguard endangered species. Liana Joseph/Author provided, CC BY-ND

To be clear, protecting some of these landscapes is incredibly valuable. This is especially true given the current and future impacts of climate change. And in Australia, we’ve done well to protect nearly half of intact ecosystems by including them in nature reserves.

But protecting intact ecosystems is just one piece of the conservation puzzle.

Getting our priorities right

Australia has committed to protect 30% of our lands and waters by 2030. This is known as the “30 by 30” target. We are also a leader in the so-called high ambition coalition of 124 countries which have pledged to meet this same target.

But to protect our biodiversity we need to focus on which land is protected, not just how much. A hectare in the wrong place will have little effect, while a hectare in the right place can be the bridge between survival and extinction.

So as Australia moves towards the “30 by 30” target, the key challenge will be ensuring we protect land strategically, not opportunistically.

The good news is, we now have the tools to do so. Australia has some of the best biodiversity data in the world. This is because the Australian government has invested in ecologists from around the country, allowing them to closely study endangered species.

However, what we’re missing is a commitment to use this information. So far, we’ve largely measured progress using one blunt metric: total area protected. This metric is easy to communicate but is dangerously misleading. It tells us very little about whether protected areas are in the right location or are being managed well.

If we’re serious about halting species extinctions within the next five years, we need to change course now. Here are three ways to do that.

• urgently protect areas of highest biodiversity value, especially the habitats of species on the brink of extinction
• prioritise under-protected ecosystems instead of those which are easiest to conserve
• start measuring success in terms of outcomes, not just area.

Without this shift, we risk meeting our “30 by 30” target while failing to save our most threatened species and ecosystems. That would be a hollow victory.

New AI Glasses for Dementia ‘Sees’ Objects With Labels Projected on Lenses to ‘Significantly’ Improve Lives

Carole Grieg testing the CrossSense AI glasses – SWNS

New AI glasses for people with dementia are able to project visual prompts onto the lenses to help folks live more independently—and they could be available in the UK in 2027.

The latest news comes after the glasses wowed both test patients in their homes and a panel of outside judges.

They can guide people living with early-stage dementia through daily activities by identifying common objects and providing audio commentary or answer questions while projecting visual prompts onto the lenses.

By asking gentle questions, the glasses’ AI companion, called ‘Wispy’, understands and learns a person’s unique way of doing things, with the AI adapting to each user’s needs as their dementia progresses.

Wispy will even talk through what to do when a person cannot remember a particular step in a process.

In test trials, three out of four patients reported a significant improvement to their quality of life, thanks to the glasses and Wispy’s tips developed from UK company CrossSense.

Spending over a decade creating and tweaking prototypes of the app and gadget, a team of AI engineers trained the glasses with dozens of everyday activities including getting dressed, managing household chores safely, making a cup of tea and interacting with loved ones.

The specs, which work with people’s prescription lens inserts and hearing aids, also capture the environment of the person living with dementia and the AI interprets that information to help the user to do the things that define independence.

“This includes feeling confident in their own home, taking good care of themselves, planning the day ahead, completing planned activities and hosting friends and family,” said the creators.

With a release date set for early 2027 in the UK, the inventors hope the specs, which weigh less than 3 ounces (75g), will be used by local authorities, care providers, and NHS hospital memory clinics.

Last week, the London-based team behind the technology, CrossSense, won the Longitude Prize on Dementia with its million dollar prize funded by the Alzheimer’s Society and Innovate UK.

The panel of international expert judges agreed that the winning solution was a genuine breakthrough technology with revolutionary potential for people living with dementia and their families.

CrossSense says the gadget includes a built-in battery that lasts for one hour, but also a portable power bank that can keep the glasses running all day long.

70-year-old Carole Grieg from London (pictured above), who founded a dementia support group called ForgetMeNots, tried the new glasses and is convinced they could help her fellow dementia patients maintain their independence.

“I thought it was an amazing concept, with the potential to provide real, reliable support for people like me, helping to compensate for the cognitive skills we gradually lose as dementia progresses.”

“For many of us, our world slowly becomes smaller as the condition progresses. Innovations like this offer real hope, and I know that as my own circumstances change, I will certainly be relying on them.”

Professor Fiona Carragher, chief research officer at Alzheimer’s Society admires the way the technology can develop its ‘intuitive personal support’.

“By anticipating people’s needs as their condition progresses, easing daily living challenges, and providing reassurance to families, this revolutionary tech will allow people with dementia to maintain their independence for longer, within the familiar environment of home.” New AI Glasses for Dementia ‘Sees’ Objects With Labels Projected on Lenses to ‘Significantly’ Improve Lives

Surgeons Perform First-Ever Surgery for Critically-Endangered Monkey Weeks Before She Gave Birth

Chester Zoo via SWNS

GNN often stays abreast of births among the Chester Zoo’s incredibly diverse residents of rare and endangered species, but few have ever been cuter or rarer than this Roloway monkey.

Chester Zoo is one of only two places in the UK that Roloway monkeys can be found, a spokesman said, and the breeding population there supports the animal as conservationists ponder what to do to ensure it can survive in its West African home.

The mother is named Masaya, and before the 15-year-old primate gave birth to a daughter named Lagertha, she was the first ever Roloway monkey to undergo surgery in captivity—to remove a golf-ball sized abscess from her foot.

Masaya had to have one toe amputated during the procedure, which was done at the University of Liverpool’s Small Animal Teaching Hospital.

“Masaya is a very experienced mom and she’s parenting magnificently,” said

Zoe Edwards, primate keeper at Chester Zoo. “The fact Masaya’s foot has healed so well is a huge relief. If she’d had a [full] amputation, we’d have been left with real questions about whether she could hold her offspring or continue with her normal behaviors.”

Roloway monkeys originate from West Africa and are listed as Critically-Endangered by the International Union for Conservation of Nature (IUCN). Once common in the lush rainforests of Ghana and the Ivory Coast, the Roloway monkey now survives only in isolated pockets of old-growth forest.

Chester Zoo witnessed the first birth of a Roloway monkey in captivity in 2020, and Lagertha is the 3rd to be born since then. Edwards said it marked an important moment in the species’ conservation. There are only a few breeding females in zoos in Europe, and only one other in England at the Yorkshire Wildlife Park.

Masaya had experienced recurring problems with her foot since she came to the zoo in 2023. It was determined to be an abscess, and when the swelling worsened in 2025, the decision was made to take Masaya to Liverpool for a CT scan.

“It’s not every day you take a monkey to vet school,” said Charlotte Bentley, Veterinary Officer at the zoo’s Animal Health Center. “Following the scan, we decided an operation was the way forward.”

According to the New England Primate Conservancy, the Roloway monkey is now considered one of the most urgently threatened primates in the entire world. A big-bodied monkey, they have been hunted to such small populations that, ironically, they’re now considered too uneconomical to pursue anymore, and so have inadvertently gained a short respite from poaching.

he conservancy admits that the most likely chance for survival is for breeding programs like the one at Chester to continue the propagation of the species until such a time as their native forests in Ghana and the Ivory Coast can be appropriately and reliably protected from poachers and logging.

He Made a Battery Pack Using Disposable Vapes to Power His Electric Car (WATCH)

Chris Doel powers electric car with disposable vape batteries – SWNS

A man has powered an electric car using a homemade battery pack built out of discarded vapes, on a quest to show that so many valuable resources are being cast off every day.

Last year, GNN reported that Chris Doel had stripped down the lithium batteries from 500 disposable vapes, power sources he describes as “fully rechargeable”, to create a power-bank big enough to run his home.

Not willing to stop there, the 27-year-old engineer then decided to reuse the battery pack to power a trip in an electric car.

He needed a vehicle with a small battery so bought a 2007 G-Wiz for £800—named the worst car that year by Top Gear—and spent five months working on the project. He finally took it out for a spin last month.

The young man from Warwickshire, England, who calls himself “the engineer equivalent of a mad scientist”, documented the process on his YouTube channel, which has 164,000 subscribers. (Watch his new car video below…)

He went to the local vape shop last May asking if they would donate their “returns” for his house-battery project. He walked away with bags containing 2,000 vapes.

It took him six months during his free time at home, outside Birmingham, to extract the rechargeable lithium batteries from the devices. He then used a 3D printed case to combine 500 cells wired in parallel into groups connected in series to make a massive battery pack.

27-year-old Chris Doel powers EV with disposable vape batteries – SWNS

The completed pack successfully powered his house for eight hours, before finally running out of juice. Immediately, he set his sights on his next project: the car.

“I was speaking with a colleague about how I wanted to power a vehicle, but because EVs have such enormous batteries, I thought it was never going to be possible,” Chris told SWNS news agency.

“My colleague came up with the genius idea of using the G-Wiz. It’s pretty much the only car out there with a 48v battery, (meaning) the power-wall would work with it.

The micro-car only requires a battery with a voltage of 48v—well below Tesla’s 400v. It has a max speed of just 50 mph, yet seats two adults and two small children.

It ran for two hours, covering a distance of 18 miles—entirely powered by vape batteries.

What about the flammability?

Chris bought insurance to cover liability, and was happy to pay around $700 for one year, saying, “Given the fact they’re taking the risk of it being a battery pack literally made of vape cells, it was incredibly cheap in the grand scheme of things.”

He spent five hours a day after work on weekdays, and 12 hours a day on weekends, for five months rewiring the car and sorting out the legal paperwork before he was finally able to take it out for a spin.

“I stripped it all back to re-do all the wiring, making sure it was proper sturdy. I made a big enclosure—worst-case scenario—in case it were to go up in flames. I would want it to be at least somewhat contained and not be rattling all over the place.”

Now, Chris has taken the vape batteries out of the car and replaced them with two Tesla battery modules, but runs it with “special software to fool them into thinking they’re installed in a Tesla Model 3.”

Today, the car is his daily transportation.

“As soon as I get an idea in my head, I’m determined to get it done.”

As an environmentalist who is outraged by the “planned obsolescence”of these disposable vapes, he urges everyone to stop buying the wasteful product which ends up in the landfill within days of purchasing.Instead, he urges manufacturers to build rechargeable products with long lives that are recyclable to help create a circular economy.

Elusive Nightjar Populations Doubled in 5 Years, a ‘Remarkable Comeback’ Conservationists Say

The population of one of England’s most-elusive birds is flourishing again thanks to conservation efforts in the south of the country.

The nightjar, sometimes called the nighthawk, becomes active at twilight, and they’re famous for their chortling calls and fantastic camouflage.

Their numbers declined some 51% between the 1970s and 2000s after substantial forest loss.

The UK’s South Downs National Park stretches across the areas of Hampshire, West Sussex, and East Sussex, and it’s among the lowland heath and forests that nightjars have staged a remarkable population recovery.

A nightjar survey in the park last year counted more than 70 birds, which is believed to mark a doubling over the last 5 years. The animals migrate 4,000 miles north from the Democratic Republic of the Congo to reside in the UK between April and August. Meanwhile, forest and heathland restoration efforts have raised the number of good nesting habitats to 109 across Britain.

The birds nest on the ground, so conservation work has specifically focused on communication with visitors to places like South Downs. They’re encouraged to keep their dogs on leashes, stay on marked trails, and avoid bushwhacking so as not to disturb or destroy the sensitive nesting areas.

“It’s wonderful to hear the nightjars churring away as dusk falls and we’re looking forward to continuing this incredibly positive conservation work alongside local communities and our partners,” South Downs ranger Kirsty Murray told the BBC.

Murray called good nightjar habitat “as rare as rainforest” in Britain, and thought it was the best thing in the world that the animal was repopulating the park.The nightjar is an extremely versatile and successful species. They inhabit all continents but Antarctica, and can live at virtually any elevation within reason. They steer clear of extremely arid regions, and can migrate long or short distances.

EV Charging Answer: Quantum Technology Will Cut Time it Takes to Charge Electric Cars to Just 9 Seconds

Institute for Basic Science

Scientists in South Korea have proven that a new technology will cut the time it takes to charge electric cars to just nine seconds, allowing EV owners to ‘fill up’ faster than their gasoline counterparts.

And even those plugging-in at home will have the time slashed from 10 hours to three minutes.

The new device uses the laws of quantum physics to power all of a battery’s cells at once—instead of one at a time—so recharging takes no longer than filling up at the pump.

Electric cars were rarely seen on the roads 10 years ago, but millions are now being sold every year and it has become one of the fastest growing industries, but even the fastest superchargers need around 20 to 40 minutes to power their car.

Scientists at the Institute for Basic Science (IBS) in South Korea have come up with a solution. Co-author Dr. Dario Rosa said the consequences could be far-reaching.

“Quantum charging could go well beyond electric cars and consumer electronics. For example, it may find key uses in future fusion power plants, which require large amounts of energy to be charged and discharged in an instant.”

The concept of a “quantum battery” was first proposed in a seminal paper published by Alicki and Fannes in 2012. It was theorized that quantum resources, such as entanglement, can be used to vastly speed up battery charging.

The researchers used quantum mechanics to model their super fast charging station with calculations of the charging speed showing that a typical electric vehicle with a battery containing around 200 cells would recharge 200 times faster.

Current collective charging is not possible in classical batteries, where the cells are charged in parallel, independently of one another.

“This is particularly exciting as modern large-capacity batteries can contain numerous cells.”

The group went further to provide an explicit way of designing such batteries.

This means charging times could be cut from 10 hours to three minutes at home and from around 30 minutes to just a few seconds at stations.

Co-author Dr Dominik Šafránek said, “Of course, quantum technologies are still in their infancy and there is a long way to go before these methods can be implemented in practice.”

“Research findings such as these, however, create a promising direction and can incentivize the funding agencies and businesses to further invest in these technologies.

“If employed, it is believed that quantum batteries would completely revolutionize the way we use energy and take us a step closer to our sustainable future.”

The findings were published in the February 8 edition of the journal Physical Review Letters. [GNN updated the earlier broken link.] EV Charging Answer: Quantum Technology Will Cut Time it Takes to Charge Electric Cars to Just 9 Seconds

Great Lakes Otters Are a Conservation Success Story with Populations Flourishing in US and Ontario

In 1986, Ohio’s Department of Natural Resources began reintroducing North American river otters to the rivers, creeks, and shorelines of the Great Lakes ecosystem.

40 years later, these adorable apex predators have recolonized much of their former aquatic acreage in Ohio, New York, Michigan, and Ontario, fastening the food chain at the top while ecosystem restoration programs have anchored it at the bottom.

The Great Lakes region holds one-fifth of the world’s fresh water. It’s a massive ecosystem that supports tens of millions of people, tens of billions in industry, and thousands of animal and plant species.

Unfortunately for the otter, an apex predator needs a vast and intact ecosystem to thrive, and as industrialization ate away at its prey species and den habitat, hunters reduced their numbers in pursuit of their pelts.

In 1980, an examination conducted on US river otter populations determined they were locally extinct in 11 states, and lost significant population in 9 other states.

It’s a story all-too-familiar the world over, but one that seems now to have had a happy ending.

After the Ohio DNR began releasing river otters from southern states like Arkansas and Louisiana, New York state began a mirrored effort of relocating otters from the Adirondacks, the Hudson Valley, and Catskills to the tributaries of the Great Lakes in the western part of the state.

“All of these efforts were bolstered by the 1972 Great Lakes Water Quality Agreement, a landmark US–Canada treaty that pushed both countries toward reducing toxic discharges and restoring damaged habitats,” writes Timothy Mihocik at Rewilding Magazine.

Gradual waterfront revitalization and de-industrialization has allowed the otter to go beyond mere sheltered streams in protected areas back into the heart of the Great Lakes ecosystem, a return that also heralds cleaner, uncontaminated water, richer fish stocks, and more biodiverse riverbeds.

GNN has reported over the years that the character of several Midwest rivers, once so polluted they’d catch fire, has now changed. In Toronto, Ohio, and Chicago, rivers are now swimmable and fishable again, and otters stand hugely to benefit from that.Still, North American river otters have remained rare or absent in the southwestern United States. Water quality and development inhibit recovery of populations in some areas, but here too, otters are returning, with the New Mexican population tripling in the last few years.

Couples share 30% of their gut bacteria. Here’s how that may affect health

Conor Meehan, Nottingham Trent University and Janelle Mwerinde, Nottingham Trent University

When living with a partner, you might be sharing more than just the same home, lifestyle and interests. You might also share various microscopic organisms residing on and in you.

This community of microorganisms, which consists of mainly bacteria, viruses and fungi, is known collectively as the human microbiome. The various microbiomes found throughout the body all play an important role in health.

From birth, the human microbiome is shaped by our interactions with our mother, who introduces diverse microorganisms that build our immune and digestive systems. As we get older, social interactions with our close community continue influencing this delicate ecosystem.

The people we live with have huge influence on what microbes we have in our microbiome. In fact, it’s thought that partners share around 30% of their resident microbes in the gut alone.

But it isn’t just the microbes in your gut that may be similar to your partner. The microbes in many other parts of the body may also be shared with your loved one – and this could potentially affect your health.

Gut microbiome

Diet and lifestyle are thought to have the greatest influence on the gut microbiome’s make-up. But studies on couples have found that living with your partner can also influence the microbiome.

Couples living together may share 13% to 30% of their gut bacteria. This was true even when diet (which many couples share) was factored out. Research also shows that couples who live together have greater microbial diversity compared to people who live alone.

This is good news for couples who co-habitate, as a more diverse gut microbiome is correlated with lower risk of irritable bowel syndrome, cardiovascular diseases and potentially high blood sugar.

But it might not all be good news. Research shows that some of the bacterial species couples share can have varying effects on health.

Take the bacteria from the Ruminococcus family. While some species of Ruminoccocus benefit health, others have been linked to negative health outcomes, including diabetes and irritable bowel syndrome.

So these bacteria may not always offer the same benefits in different demographics. This highlights the complexity of resident gut bacteria and their health impacts.

Oral microbiome

Sharing an oral microbiome with our partners might seem obvious considering we regularly exchange saliva when we kiss. A ten-second kiss alone can exchange up to 80 million bacteria. The more kisses a couple shares, the more shared salivary bacteria they will have.

Although most of these bacteria will quickly pass through our mouth and into our gut when we swallow saliva, research show that couples actually share many of the same longer-term tongue microbes that form the foundation of the oral microbiome. Research even suggests that 38% of the oral microbiome is shared in couples living together – compared to only 3% in couples who don’t live together.

Sharing this proportion of your oral microbiome could have many potential health effects.

A healthy oral microbiome is important for protecting against tooth decay and it has anti-inflammatory properties. Some researchers also suggest the oral microbiome’s health effects may extend as far as the gut and nervous system.

But some of the bacteria that couples tend to share may also have potentially harmful health effects.

Couples are more likely to have similar numbers of the bacteria Neisseria in their gut compared to single people. Neisseria can reside in the mouth for long periods of without causing disease.

Some Neisseria bacteria can be harmful and may cause meningitis. Yet some Neisseria bacteria actually fight against these meningitis-causing species, stopping them from overgrowing and causing harm.

So while you may want to avoid kissing someone when they’re poorly for obvious reasons, it turns out that a kiss even when you’re healthy can transfer all sorts of bacteria between the two of you.

More research is needed to really understand what overall effect sharing these bacteria with your partner has on health.

Skin microbiome

The skin microbiome is the most unique and personalised microbiome, tailored to each person. It’s even sometimes referred to as our microbial fingerprint.

Being the most exposed microbiome, the skin microbiome has evolved to be adaptable to external factors such as the climate and cosmetic products. No matter what, these bacteria work hard to remain at an equilibrium.

Close contact with our partners – and even pets – has a huge influence on what bacteria live on our skin. After comparing the gut and oral microbiome, researchers found the skin microbiome to be the most similar among couples.

It isn’t just the bacteria on your arms or hands that are shared, either. Research shows that couples shared 35% of the bacteria living on their feet, and around 17.5% of the bacteria on their eyelids.

You may not even need to touch your partner to have the same skin bacteria as them. Factors such as sleeping in the same bed and walking on similar surfaces are thought to explain why such a large proportion of our skin microbiome is similar.

This is because humans naturally shed bacteria in a similar way as dogs shed fur. We leave traces of our bacteria on everything we touch – and we also easily pick up bacteria from our environments.

The shared effect of living together on the skin microbiome is so great that researchers were able to use computer models to accurately predict 86% of cohabiting couples based off of their individual bacterial samples alone.

But while it’s clear that couples share much of the same skin microbiome, the health effect that this has is not currently known.

While sharing bacteria with your partner may sound alarming, there’s often no cause for concern. Bacteria teach our bodies how to fight infections, they help us digest foods and even produce key nutrients. The bacteria we share with our partners are often harmless and sometimes benefit our health rather than hindering it.

Human vision: what we actually see – and don’t see – tells us a lot about consciousness

Henry Taylor, University of Birmingham

What can you see right now? This might seem like a silly question, but what enters your consciousness is not the whole story when it comes to vision. A great deal of visual processing in the brain goes on well below our conscious awareness.

Some studies have probed the unconscious depths of vision. One source of evidence comes from the neurological condition known as blindsight, which is caused by damage to areas of the brain involved in processing visual information. People with blindsight report that they are unable to see, either entirely or in a portion of their visual field. However, when asked to guess what is there, they can often do so with remarkable accuracy.

For example, in an experiment published in 2004 on someone with blindsight, a black bar was displayed in the portion of the visual field to which the person was blind. The person was asked to “guess” whether the bar was vertical or horizontal.

Despite denying any conscious awareness of the bar, the participant could answer correctly at a level well above chance. The participant even showed evidence of being able to pay attention to the bar – they were faster to respond when an arrow (placed in a healthy area of their visual field) correctly indicated the location of the bar.

The most popular interpretation (though not the only one) is that people with blindsight can see these objects, but not see them consciously. They see what is there, but it all goes on unconsciously, below their awareness.

The phenomenon of inattentional blindness seems to show you can see without the information crossing into your consciousness. Anyone can experience inattentional blindness. The phenomenon has been known about for a long time, but we can most easily get a handle on it by looking at a well-known experiment reported in 1999.

In this experiment, participants are shown a video of people playing basketball, and told to count the number of passes between the players wearing a white shirt. If you’ve never done this before, I urge to you stop reading now and watch the video.

In many cases, people are so busy counting the passes that they completely miss a large gorilla walking across the middle of the scene and beating its chest, then walking off. The gorilla’s right there, in the centre of your visual field. Light from the gorilla enters your eyes, and is processed in the visual system, but somehow you missed it, because you weren’t paying attention to it.

The gorilla has more to teach us. In another experiment reported in 2013, radiologists were given a series of lung scans. They were told to look for nodules (which show up as small light coloured circles) on each scan. In one of the scans, a large picture of a dancing gorilla was superimposed on top of the lung scan. In this study, 83% of the radiologists failed to spot it, even though it was 48 times bigger than the average nodule they were looking for. Some of them even looked directly at the gorilla and still didn’t notice it!

The interpretation of these experiments is controversial. Some scientists suggest that in these kinds of cases, you consciously see the gorilla, but immediately forget it (although a dancing gorilla in someone’s lung doesn’t seem like the kind of thing you’d forget). Others argue that you see the gorilla, but the information never made its way into consciousness. You saw the gorilla, but unconsciously.

Let’s assume that in the case of blindsight, and inattentional blindness, the information is seen, but didn’t make it all the way to consciousness. Then, the question is: what makes some information conscious, rather than the information that stays unconscious? This is one of the central questions for consciousness studies in philosophy, psychology and neuroscience.

The brain’s loudspeaker

There’s no agreement on which is the best theory of consciousness, but in my opinion, the strongest contender is the global neuronal workspace theory.

According to this theory, consciousness is all to do with a particular area of the brain which is the seat of the “workspace”. The workspace is a system with a small capacity, so it can’t hold a lot of information at any one time. The job of the workspace is to take unconscious information and broadcast it to lots of different networks all across the brain. Global neuronal workspace theorists say that broadcasting the information in this way is what makes it conscious.

The job of the workspace is to act like the brain’s loudspeaker, and consciousness is the information that gets broadcast. The workspace takes unconscious information and boosts it so that many of the different systems in the brain hear about it and can use that information in their own processes. The late philosopher Daniel Dennett used to call consciousness “fame in the brain”. The workspace idea is similar.

One of the most striking implications of the global neuronal workspace theory is how little information makes it to consciousness. Since the workspace has quite a small capacity, it follows that we can only ever be conscious of a little at a time. We might think there’s a rich visual world in front of us, full of details, all of which we’re conscious of, but really – according to the theory – we’re only ever conscious of a small portion of that.

Some philosophers and scientists have objected to the theory on these grounds. They suggest that consciousness “overflows” the workspace: we are conscious of more information than can “fit” into the workspace at any one time. Even with these debates still ongoing, I think the global neuronal workspace theory gives us a reasonably clear answer to the question of what consciousness is for, and how it interacts with other systems in the brain.

In our brains, consciousness is only the tip of a very large iceberg. But the global neuronal workspace theory might give us insight into what makes that tip so special.
