The classic little black dress just got a high-tech makeover.

A team at Cornell University has created the darkest fabric ever made — a soft, wearable textile that reflects just 0.13% of light, earning it the title of “ultrablack.” The breakthrough, published in Nature Communications, merges fashion with science and takes its cues from nature’s original masters of dark style: magnificent riflebirds.

Riflebirds, native to New Guinea and known for their striking courtship dances, sport feathers so black they seem to swallow light. That illusion is more than just pigment — it’s a trick of structure. The birds' feathers contain layers of tiny barbules that bounce and trap light, enhancing the depth of blackness. And now, researchers have managed to mimic that same optical magic in fabric.

“The light basically bounces back and forth between the fibrils, instead of reflecting back out — that’s what creates the ultrablack effect,” explained Hansadi Jayamaha, lead author and Ph.D. student in Cornell’s Department of Human-Centered Design.

To replicate the birds’ plumage, the team dyed white merino wool with polydopamine, a synthetic melanin that mimics the natural pigment found in the birds. Then, they used plasma etching — a technique more common in electronics — to carve nanoscale structures into the fabric, giving it the same light-trapping qualities found in riflebird feathers.

The result? A soft, breathable, stretchable textile that’s blacker than any other fabric on record — and one that stays black no matter the angle you view it from.

“From a design perspective, I think it’s exciting because a lot of the ultrablack that exists isn’t really as wearable as ours,” said Larissa Shepherd, the project’s senior author and a materials scientist at Cornell. “And it stays ultrablack even from wider angles.”

That’s a big deal. Previous attempts at creating ultrablack materials — including one that reflected just 0.005% of light — involved toxic, fragile, or rigid substances that made them impractical for clothing or everyday use. This new textile, by contrast, is flexible and safe, opening the door to a range of real-world applications.

The team showcased its discovery with a nod to fashion history: they used the fabric to sew a tiny black dress, adding a flash of iridescent blue in tribute to the riflebirds that inspired it.

Beyond fashion, the material could have serious implications for industries like aerospace, solar energy, and optical engineering. Ultrablack materials are highly sought after for use in telescopes, cameras, and solar panels, where reducing stray light can dramatically boost performance.

But it's not just about optics. The fabric is also a case study in biomimicry — the practice of looking to nature for engineering inspiration. By studying how birds achieve one of the darkest colors in the natural world, researchers found a way to solve a challenge that has long frustrated materials scientists.

Ultrablack, in this context, isn’t just a color — it’s a measure of how little light is reflected. Anything that reflects less than 0.5% of incoming light qualifies. Riflebird feathers, and now this fabric, hit that mark effortlessly. That makes it not just dark to the eye, but almost invisible under certain lighting conditions.

The team has already filed for provisional patent protection and hopes to bring the material to market soon. For now, the little ultrablack dress stands as proof of concept — and a striking example of how science can be as stylish as it is functional.

Skywatchers, mark your calendars — the aurora borealis may be putting on a rare holiday-season show this week, thanks to a powerful solar flare and a burst of energy hurtling toward Earth.

Forecasters at the National Oceanic and Atmospheric Administration (NOAA) say the northern lights could become visible on Wednesday night, Dec. 3, and continue into the early hours of Thursday, Dec. 4, across parts of the northern U.S. and upper Midwest.

The spark? A recent X2-class solar flare — one of the strongest categories — and a coronal mass ejection (CME), both of which erupted from the sun on Monday. When those charged solar particles reach Earth, they interact with the planet’s magnetic field and atmosphere, creating the vibrant green, purple, and red waves known as auroras.

According to SpaceWeather.com, the CME may “graze our planet on Dec. 2,” possibly scooping up a solar wind stream in the process — which could boost the impact and trigger a stronger geomagnetic storm.

What kind of aurora activity is expected?

NOAA is currently forecasting a G2 geomagnetic storm, which is considered moderate. If conditions line up just right, there's a chance it could briefly intensify to G3, a strong-level storm that dramatically increases aurora visibility across more of the U.S.

Where might the northern lights be visible? 
If the storm remains at G2 strength, look north from states like:
• Alaska
• Washington
• Idaho
• Montana
• North and South Dakota
• Minnesota
• Wisconsin
• Michigan
• New York
• Maine

If it hits G3 levels, the lights could dip farther south and be visible in parts of:

• Oregon
• Nebraska
• Iowa
• Illinois
• Indiana
• Ohio
• Pennsylvania
• Vermont
• New Hampshire
• Massachusetts

Best tips for seeing the aurora:
• Head away from city lights. Find a dark, open spot with a clear view of the northern horizon.
• Check real-time alerts on NOAA’s aurora dashboard or use apps like Aurora Now, My Aurora Forecast, or Glendale Aurora.
• Be patient. Auroras can fade in and out, so give yourself plenty of time.

No fancy gear? No problem.
• On an iPhone, turn on Night Mode.
• On Android, switch to Pro Mode.
• Turn off the flash, hold your phone steady (or use a tripod), and let your camera adjust.

If you’re using a DSLR, go with a wide-angle lens, crank up the ISO, and try longer exposure times to capture the subtle colors and swirling patterns.

Whether you're in a northern state or just keeping an eye on the forecast, this week offers a rare chance to see one of nature’s most stunning shows — no airfare to the Arctic required.

Here's How You Can Witness Back-to-Back Northern Lights Displays This Week

Archaeologists digging beneath the Palace of Westminster — home to the UK Parliament — have uncovered a sweeping record of human activity that stretches from prehistoric toolmakers to Victorian stonemasons.

The discoveries, made by the Museum of London Archaeology (MOLA) as part of Parliament’s Restoration and Renewal Program, include 6,000-year-old flint tools, remnants of a long-lost medieval hall, Roman-era artifacts, and even 19th-century beer jugs and tobacco pipes.

“The Palace of Westminster has been a central part of our national story for a thousand years,” said Simon Thurley, chair of the program’s Delivery Authority. “As we plan for its restoration, we must tread softly on the history beneath our feet.”

Prehistoric London, revealed

Among the most surprising finds were 60 pieces of prehistoric flint, including a tool and sharp-edged flakes used in tool-making. Dating to around 4300 BCE — the late Mesolithic or early Neolithic period — the fragments were discovered in sand deposits that once formed part of Thorney Island, a raised area along the River Thames that attracted early human settlement.

“While research suggested we might find traces of early human activity on the site, I was surprised to discover direct evidence of flint tool-making,” said Diane Abrams, archaeology lead for the Delivery Authority. “Finding prehistoric remains in central London is incredibly rare.”

Researchers believe the site may have been used by early inhabitants for fishing, hunting, and gathering, adding a new layer to London’s deep past.

Medieval halls and fiery ruins
The excavation also revealed substantial remains of Lesser Hall, a two-story building constructed in 1167. Originally a royal dining space, it later housed various legal courts, including the Court of Chancery and the Court of Requests, and was even used at times by the House of Commons and House of Lords.

One of the hall’s roles, through the Court of Requests, was to hear civil petitions from poor citizens and royal servants — essentially a venue for those without the means to access other courts.

In 1834, while functioning as the temporary seat of the House of Lords, the Lesser Hall was engulfed in what became known as the Great Fire of 1834. Yet the excavation found that large portions of the stone walls survived the blaze and that the building was reroofed and used until its demolition in 1851.

“The Lesser Hall walls are the most significant discovery of the current archaeological investigations,” the program noted in a statement, offering “vital insights into the layout and survival of historic structures beneath the modern palace.”

Abrams called the survival of the building “one of the most exciting and unexpected” finds of the dig.

Roman altars and leather shoes
Other notable discoveries include a fragment of a 2,000-year-old Roman altar, likely reused in a later building, and an assortment of medieval personal items: 800-year-old shoe soles, leather straps, a boot, and a heart-shaped badge from the 14th or 15th century — possibly worn as a token of love.

The 19th-century layers of the site revealed more recent relics: broken clay tobacco pipes likely used by stonemasons rebuilding after the fire, and a large five-pint beer jug marked with “Ship and Turtle Tavern” and “Geo Painter,” referring to the tavern and its owner at the time.

Together, these finds “reveal a remarkable timeline of human activity on this iconic site,” Abrams said, adding that the discoveries will help guide the sensitive restoration of the aging Parliament buildings.

Before being reburied for preservation, many of the remains — including the Lesser Hall — were carefully documented and turned into 3D models.

As Parliament prepares for extensive restoration, the archaeology beneath its foundations serves as a reminder: Britain’s seat of power is also a layered time capsule, preserving stories that stretch back thousands of years.

6,000-Year-Old Tools and Medieval Ruins Were Just Unearthed Beneath the UK Parliament

Every weekend in Nairobi, a striking scene plays out. Dozens of women swap their office heels and work uniforms for leather jackets, biker boots, and helmets — revving their motorcycles and heading out as a pack.

They call themselves the Inked Sisterhood.

Formed in 2017 out of a Nairobi riding school, the group has become one of Kenya’s fastest-growing female biker communities. Its members come from all walks of life: scientists, lawyers, civil servants, and marketing executives. What started as a space for women to feel less outnumbered on the road has grown into something bigger — a community built around freedom, friendship, and challenging stereotypes.

“Over the years, we've grown to having over a hundred members,” says Lucy Monyenye, an advocate of the High Court of Kenya who also helps coordinate the group. “The numbers keep growing and reducing just because at times life happens.”

To keep things organized, the Sisterhood officially registered the club. “For continuity purposes,” Monyenye says, “so that we can have some form of institutional memory around the club.”

Their presence is impossible to miss. What was once considered a masculine pursuit has become, for these women, a symbol of independence — and a break from daily routine.

“Among ourselves, if someone's had a baby or someone's going through something and things are tough, we visit the family,” says Amanda Khamati, a marketing consultant and rider. “So apart from just biking, we socialise, we hang out together.”

The bike rides are about more than just speed or adrenaline. For many, it's about reclaiming a sense of power.

“When I sit on a motorbike, I feel powerful,” says scientist Kisianan Kenana. “Of course everyone thinks riding is for men, and I am one of those women who are here to show you that everyone can do it.”

Still, gender stereotypes remain stubbornly in place.

“Most people think being a female biker you're slower than the men, you can't do long distances, you get tired quickly, and also you're a tomboy,” Kenana says. “You're stubborn, and you just love adrenaline. Yes, the last part might be true, but the rest...” She shakes her head and laughs.

But perspectives are starting to shift.

Michael Othieno, a tax consultant and fellow motorbike enthusiast, has seen the change up close.

“The difference between women and us is that the women seek out training more and more and more, a lot more, and have become better at it,” he says. “So much so that when they remove their helmet and you actually see there's dreadlocks or there's braids under that helmet, you can really tell that they've taken it up and they're as good as men — some even better.”

Beyond the social side, the Inked Sisterhood has a community mission. The group has helped promote road safety and organised charity rides, tree planting sessions, memorial events, and mixed-gender awareness campaigns.

In a country where public roads have often been seen as unsafe or unwelcoming spaces for women, the Sisterhood isn’t just riding — it’s leading.

Every time they kick up their kickstands, they’re making a point: This space is for everyone.

For more than a decade, Tina Hutcherson has safely driven kids to school in the Putnam City School District in Oklahoma. But this winter, she’s doing more than just making sure they get there on time — she’s making sure they stay warm, too.

At 63, Hutcherson has been knitting and crocheting since she was 12. When her daughter recently gifted her a new knitting machine for her birthday, Hutcherson immediately put it to good use. The machine cuts her time to just 30 minutes per hat — fast enough that she decided to make one for every student who rides her bus.

“I said, oh Lord, I’m gonna make every one of them babies on the bus a hat,” she told KOCO News 5. “I just don’t want nobody to be without, especially when they're riding with me.”

Hutcherson drives about 100 students to school each day, from elementary through high school. So far, she’s handed out 25 hats to her youngest riders — and they’ve responded with hand-written thank-you notes.

Each student gets to choose their own colors, and the hats are reversible. Hutcherson calls them her “bus babies,” and they’re the heart of the project.

“I got enough yarn to make any hats I wanna make, and colors,” she said. “I’ve been stocking up since I was 12. So if these kids need a hat, coat, I like making ponchos for them, I don’t care — they’re gonna get it.”

For Hutcherson, it’s not just about staying warm. It’s about making sure the kids feel loved. According to Nonprofit Quarterly, two out of every five children in the U.S. are clothing-insecure, meaning they may not have access to season-appropriate clothes or the right sizes. Hutcherson is doing what she can to close that gap — one stitch at a time.

“I just hope they take away that somebody loves 'em, and that’s all,” she said. “And if they don’t have any love at home, they gonna get on this bus in the morning… they always know they can always talk to me about anything. I want them to be safe.”

Hutcherson shares photos of her creations on Facebook, sometimes posting other hats she’s made for coworkers or community members. But the ones she knits for her morning route hold a special place in her heart.

“I’m so happy with my knitting machine for helping me with this project for my good babies on my morning route,” she wrote in one post. “I’m hoping they will use them and keep their heads warm for winter.”

In another post, she added simply: “I’m praying for all the [families] that are having hard times these days. Love is in the air.”

When NASA engineers want to design new ways to explore Mars, they first have to simulate the Red Planet here on Earth — extreme heat, barren terrain, and all. That’s why this year, teams from NASA’s Jet Propulsion Laboratory and other centers hauled experimental hardware into the desert to test how it might perform millions of kilometers away.

The tests, which ranged from autonomous drones in Death Valley to robot dogs in New Mexico, are part of 25 technologies funded by NASA’s Mars Exploration Program in 2025. Each one aims to help future robotic missions — or astronauts — navigate, explore, and survive on Mars more effectively than ever before.

One of the main challenges on the Red Planet is featureless terrain, like endless sand dunes. These surfaces are difficult for flying robots to navigate because they don’t offer enough visual markers for their onboard cameras to track movement.

That problem became real for NASA’s Ingenuity helicopter, which flew its final mission earlier this year after logging 72 flights on Mars. Toward the end, Ingenuity’s navigation system struggled over smooth dunes.

“Ingenuity was designed to fly over well-textured terrain,” said Roland Brockers, a JPL researcher and drone pilot. “But eventually it had to cross over blander areas where this became hard. We want future vehicles to be more versatile.”

To tackle that, Brockers and a team from JPL tested an upgraded drone navigation system called Extended Robust Aerial Autonomy in California’s Death Valley and Mojave Desert — places known for their brutal heat and Mars-like landscape. Only the third research team ever licensed to fly drones in Death Valley, the group endured 45°C heat while running software trials on three drones.

They tested different camera filters and algorithms to help the drones better track ground movement and avoid unsafe landings in cluttered areas like rocky outcrops.

The findings are already paying off. “Field tests give you a much more comprehensive perspective than solely looking at computer models,” said JPL geologist Nathan Williams. “Scientifically interesting features aren’t always located in the most benign places, so we want to be prepared to explore even more challenging terrains than Ingenuity did.”

NASA has a long history of testing Mars hardware in deserts. The twin Viking landers were prepped in Death Valley in the 1970s. A component of the Perseverance rover’s precision landing system was flight-tested over the same dunes. The agency even nicknamed one site “Mars Hill” for its Mars-like topography.

Meanwhile, another NASA team took a four-legged robot into the field this year. At White Sands National Park in New Mexico, researchers from Johnson Space Center tested LASSIE-M — a doglike robot built to scout unstable terrain.

Equipped with sensors in its legs, LASSIE-M can detect surface changes — loose sand, hard crust, soft rock — and adjust its gait accordingly. That gives it the ability to cover terrain too dangerous for traditional wheeled rovers and search for spots with scientific potential.

Out east, at NASA’s Langley Research Center in Virginia, engineers have been testing a completely different kind of robot — one that flies fast and far. It’s called MERF, short for Mars Electric Reusable Flyer. Unlike Ingenuity, which hovered like a helicopter, MERF is built for range and speed. It’s essentially one large wing with twin propellers and no tail or fuselage, designed to fly fast and skim the Martian surface while mapping features below.

The prototype, currently at half-scale, is roughly the length of a small school bus when fully deployed. Testing has focused on how the robot handles high speeds, vertical takeoffs, and lightweight materials crucial to flying in Mars’ thin atmosphere.

Other projects in the Mars Exploration Program include next-gen sampling gear, drills, and power systems — all part of a broader push to make Mars exploration more autonomous and more ambitious.

“It’s incredibly exciting to see scientists using Death Valley as a proving ground for space exploration,” said Mike Reynolds, superintendent of Death Valley National Park. “It’s a powerful reminder that the park is protected not just for its scenic beauty, but as a living laboratory.”

NASA’s goal isn’t just to explore Mars better — it’s to let robots explore it on their own, learning and adapting in real time. That means building tech that can operate in the worst terrain, in the harshest conditions, with no one around to fix it.

And to do that, the best place to start is still here on Earth — under the scorching sun, surrounded by sand, with a laptop under a canopy and a drone in the sky.

NASA is Testing a Drone In Death Valley, Prepares For Martian Exploration

At a wildlife nursery just outside Nairobi, an orphaned rhino and a zebra foal have formed an unlikely but heartwarming friendship — a bond rooted in shared tragedy and nurtured by round-the-clock care.

Tytan, a baby black rhino, and Notty, a zebra foal, were both rescued in September after their mothers died in eerily similar accidents. Though the animals came from different regions in Kenya, both of their mothers fell to their deaths off cliffs. Tytan’s mother may have been chased by a male rhino. Notty’s mother fell in a separate incident. Somehow, both calves survived.

They were taken to the Sheldrick Wildlife Trust’s Nairobi Nursery, a haven for orphaned elephants, rhinos, and other wildlife. The nonprofit is one of Kenya’s most respected wildlife conservation groups, known especially for its Orphans' Project. The nursery has helped raise and release 320 elephants and 20 rhinos so far.

Tytan and Notty now live side by side as they grow strong enough to return to the wild. They sleep in separate quarters and each has a dedicated caretaker, but during the day, they’re inseparable. According to Sean Michael, Sheldrick’s director of communication, the two “clearly enjoy spending time together, following one another throughout their days.”

Michael said interspecies friendships like theirs are “quite common among infant orphans,” especially in the early stages. “They don’t seem aware of species differences and instead operate as one big family,” he explained. “Generally, these interspecies friendships fade with time,” but for now, the two are “rarely apart.”

That connection is helping both animals heal emotionally, too.

“These special relationships help orphans overcome any emotional trauma from being orphaned, making them feel loved and accepted,” Michael said.

Despite their bond, the pair couldn’t be more different in personality. Notty is the wild child — full of energy, known for darting around, kicking, and galloping in circles. Tytan, in contrast, is calm and observant, often content to watch Notty burn off steam.

“His keepers note that he is the gentlest black rhino to ever come into our care,” Michael said. “He went through a harrowing ordeal, losing his mother so traumatically and then trying to survive on his own for two days, so he seems to appreciate being in a safe and supportive place. He is a really lovely little rhino.”

The nursery’s staff are helping the pair grow stronger each day, while gradually preparing them to survive on their own. The plan is for both Tytan and Notty to eventually reintegrate into Nairobi National Park, which has healthy wild populations of both black rhinos and zebras.

That process won’t be rushed.

“We do not force the choice to go wild,” said Michael. “Orphans leave our care when they feel ready. Reintegration is usually a very gradual process, especially for black rhinos, which are a territorial species and need time to establish their own territory.”

Until then, Tytan and Notty are free to enjoy their days in each other’s company — sharing bottle feedings, wandering the nursery grounds together, and helping one another recover from loss.

For those interested in following their story, the Sheldrick Wildlife Trust regularly posts updates on social media. Supporters can also donate to the nonprofit’s efforts or symbolically adopt Tytan through its foster program.

“They’re safe now,” said Michael. “And one day, when they’re ready, they’ll return to the wild where they belong.”

Rhino And Zebra Form Unlikely Friendship At Kenyan Wildlife Nursery

Space

Launched nearly 30 years ago, the Solar and Heliospheric Observatory — better known as SOHO — has quietly become one of the most successful and longest-running missions in space science.

A joint project between NASA and the European Space Agency, SOHO lifted off on December 2, 1995, with a bold mission: study the sun “from the inside out.” It was only meant to last three years. Instead, it’s still going strong today — three decades, three solar cycles, and more than 5,000 comet discoveries later.

From its vantage point 1.5 million kilometers closer to the sun than Earth — at the L1 Lagrange point — SOHO enjoys an uninterrupted view of our star. This unique orbital position allows it to continuously monitor the sun’s activity, from solar flares to massive eruptions known as coronal mass ejections (CMEs), the kind that can mess with satellites, power grids, and GPS systems back on Earth.

SOHO carries 12 instruments, including tools to study the sun’s interior via helioseismology — the rippling sound waves that travel through the sun’s hot plasma. It’s also equipped to observe the sun’s outer atmosphere, the corona, which remains one of the solar system’s biggest mysteries. The corona is far hotter than the sun’s surface, a counterintuitive phenomenon that still puzzles scientists. SOHO’s detailed observations have helped bring researchers closer to understanding it.

“It has transformed helioseismology,” scientists have said of the spacecraft’s contribution to our understanding of the sun’s structure and behavior.

But SOHO’s story hasn’t been without drama. In 1998, it nearly went dark permanently after engineers lost contact with it for several months. The spacecraft had begun to spin out of control and was freezing in the cold of space. NASA and ESA teams used ground-based radar to locate it, slowly regaining control and resuscitating its systems. Against the odds, they brought it back online — and SOHO hasn’t looked back since.

Over time, the mission’s value kept growing. SOHO began discovering comets — not a planned function — using a special coronagraph camera that blocks the sun’s bright face, making it easier to see faint objects nearby. As of early 2025, SOHO has discovered over 5,000 comets, more than any other observatory in history.

“SOHO has overcome nail-biting challenges to become one of the longest-operating space missions of all time,” said Prof. Carole Mundell, ESA’s Director of Science.

Even now, as the sun approaches the peak of its current solar cycle, SOHO continues to deliver daily data that scientists use to track space weather, monitor solar storms, and study long-term changes in solar activity. That data supports everything from climate science to protecting astronauts and satellites from radiation.

From saving the spacecraft in 1998 to extending its mission again and again, SOHO has quietly become a pillar of solar science. It’s seen solar flares, sunspots, and shimmering auroras. And as the sun continues to change, SOHO will likely be watching.

Human cells might soon get a second wind, thanks to a new method that teaches them how to "swap batteries" and help each other recharge.

Scientists at Texas A&M University have developed a technique that boosts the power supply of human stem cells and allows them to share that energy with weaker, aging cells. The work could lead to a new way of rejuvenating tissues affected by age or disease—without relying on drugs or genetic engineering.

At the centre of the study are mitochondria, the tiny structures inside cells that act as power plants. As we age, our mitochondria degrade. Their numbers fall, their performance dips, and when that happens, everything from our hearts to our brains can suffer.

The researchers figured out a way to give those aging mitochondria a jolt. Using particles called nanoflowers, they scavenged harmful oxygen molecules—also known as reactive oxygen species—that build up in cells and damage their internal machinery. In doing so, they flipped a biological switch that triggered stem cells to produce more mitochondria.

“We have trained healthy cells to share their spare batteries with weaker ones,” said Akhilesh Gaharwar, a biomedical engineer at Texas A&M. “By increasing the number of mitochondria inside donor cells, we can help aging or damaged cells regain their vitality – without any genetic modification or drugs.”

Those stem cells then acted like mobile charging stations, transferring the newly made mitochondria to neighboring cells that were struggling. And it worked—at least in lab experiments.

Recipient cells, marked in green in video footage from the lab, were shown to absorb new mitochondria (in red) donated by the energy-rich stem cells. In some cases, about twice as many mitochondria were shared than normal.

That boost had dramatic effects. Smooth muscle cells, which are key for heart and vascular function, increased by three to four times. In another test, heart cells that had been damaged by chemotherapy showed significantly higher survival rates after receiving the donated mitochondria.

“It’s pretty promising in terms of being able to be used for a whole wide variety of cases, and this is just kind of the start,” said geneticist John Soukar, who was part of the research team. “We could work on this forever and find new things and new disease treatments every day.”

The nanoflowers that powered the whole process are made from molybdenum disulfide, a compound with tiny holes that allow them to act like molecular sponges. By soaking up stress-inducing oxygen molecules in damaged tissue, they help reset the cellular environment—paving the way for stem cells to step in and start the energy transfer.

In theory, the approach could be targeted to specific areas of the body: injecting the stem cells near the heart for cardiovascular disease, or into weakened muscles in patients with muscular dystrophy. The method bypasses more invasive or risky procedures like gene editing, offering what Gaharwar called a “natural power-sharing system” already built into our biology.

But the research is still in its early days. So far, the technique has only been tested in lab conditions. The next step is to study how well it works in animals—and eventually, humans. Scientists will need to answer important questions about how and where these stem cells should be implanted, what dosage is safe, and what long-term effects the treatment might have.

“This is an early but exciting step toward recharging aging tissues using their own biological machinery,” said Gaharwar.

The findings were published this week in the journal Proceedings of the National Academy of Sciences (PNAS).

Scientists Just Figured Out How to “Recharge” Human Cells—No Drugs or Surgery Required

Scientists may have found a new way to check in on the health of one of the ocean’s most endangered animals — by analyzing what’s in their breath.

Researchers at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts have discovered that bacteria found in the blowhole spray of North Atlantic right whales can offer clues about the animals' condition. Their findings, published in the journal International Society for Microbial Ecology, could provide a valuable, noninvasive tool for monitoring a species with fewer than 400 individuals left in the wild.

“This is really exciting because we may have just found another way to conduct health checkups of these critically endangered whales,” said Carolyn Miller, a WHOI research associate and the study’s lead author.

Since 2016, Miller and her team have used drones to collect breath samples from whales in Cape Cod Bay. The technique involves flying a drone with a petri dish above a whale until it exhales through its blowhole. The spray lands on the dish, and the drone returns to the boat, where researchers preserve the sample for analysis.

While drone sampling isn’t new, the breakthrough came when scientists matched the breath bacteria to a whale’s physical characteristics. Using a long-running dataset that tracks things like body condition, length, skin lesions, and whale lice, they found distinct patterns. Thin whales tended to carry microbes linked to infections in mammals. In contrast, robust whales — the ones in better condition — had microbes associated with oily, fat-rich environments.

“It’s kind of like a biomarker,” said Miller. “We're still understanding what it means, but we think this might be another way to assess the health of these animals and how fat or thin they are.”

For a species under constant threat from ship strikes and fishing gear entanglements, even subtle insights like these could be critical.

The drone method is not only safer but also less stressful for the whales. Earlier techniques involved getting dangerously close to the animals in boats, using long poles to collect breath samples. Miller said the old approach was both risky and invasive.

“To get to the nostrils or the blowholes of the animal, you actually have to get quite close,” she said. “It’s very, very stressful for the animal.”

Drones changed all that. “They don’t seem to notice the drone at all,” Miller added. “It’s quiet, it’s stable, and it’s a really easy method to do.”

So far, the WHOI team has collected 103 samples from 85 individual whales.

Sean Brillant, a senior conservation biologist with the Canadian Wildlife Federation, called the study “surprising and a really novel approach.”

“What a great opportunity this tool is providing for advancing knowledge around this animal,” he said. “We have a very hard time approaching these animals, and if they don’t want to be approached, they outpace most boats and just disappear.”

Brillant noted that many right whales carry long-term injuries from entanglements or collisions. Being able to monitor their health from a distance — without adding more stress — could be a game changer.

As scientists continue to explore what these microbes can reveal, the hope is that each puff of whale breath could become another piece of a much-needed survival strategy.
