The researchers say this is one of the first studies looking at the effects of cold exposure over a prolonged period of time in people who are overweight or have obesity.

Regularly Wearing a Cooling Vest Might Help You Lose Body Fat, According to a New Study

Participants who were overweight or living with obesity wore the accessories for two hours every morning for six weeks and lost an average of two pounds. The researchers suspect showering or swimming in frigid water could have similar effects

A chick hatches around 18 days after embryo transfer to the artificial egg, according to the company.

‘De-Extinction’ Company Says It Hatched Chicks From Artificial Eggs, Paving the Way for Resurrecting Dodos and Other Bygone Birds

Colossal Biosciences announced that 26 live baby chickens have emerged from 3D-printed honeycomb structures. But the company does not plan to detail the system in a paper, and its mission has faced criticism

These Ten Breathtaking Images From the 2026 Milky Way Photographer of the Year Contest Capture the Beauty of Our Galaxy

The gorgeous astrophotographs highlight the dazzling night sky and remind viewers what we risk losing to light pollution

Each by-the-wind sailor is made of a community of genetically identical organisms called "zooids" that perform different tasks.

Millions of Bright Blue Blobs Called ‘By-the-Wind Sailors’ Are Littering Beaches Along the West Coast

The strange creatures are washing up on shores across California, Oregon and Washington this spring—and making the coast smell especially fishy

Researchers tracked children's reactions to particular food exposure when they were fetuses, newborns and then 3-year-olds.

Want to Avoid Having a Picky Eater? Start Exposing Your Kids to Veggies Super Early—in the Womb

In a new study, 3-year-olds who were repeatedly exposed to the taste of bitter kale as fetuses appeared to be less averse to the leafy greens’ scent than they were to a food smell they hadn’t experienced in utero

A visitor washes his hands before entering a hospital in the Democratic Republic of Congo as part of Ebola prevention measures.

The Ebola Outbreak in Africa Was Declared a Global Health Emergency by the WHO. Here’s What to Know About the Rare but Severe Illness

The international health agency notes that the outbreak does not meet the criteria for a pandemic, and the U.S. Centers for Disease Control and Prevention says that the risk to the American public is low

Artist's reconstruction of newly described koala species. 

A Dimpled Koala Fossil Found in a Cave in Western Australia Revealed Why This Previously Unknown Species Went Extinct

The new study found that they lost their arboreal habitat due to a drying climate, a dire warning for the modern-day marsupials that face a similar threat

In laboratory experiments, house crickets groomed an antenna that had been touched by a hot soldering iron.

Can Insects Feel Pain? New Research Suggests That Crickets Do

Used for food, feed and research, the critters are among the most widely farmed bugs. The study authors say humans should work to reduce harm in insect farming, handling and experimentation

Researchers don't know what drives whale gaping in humpback whales, but the observations posted to social media can help them identify context clues.

Humpback Whales Sometimes Hold Their Mouths Open for No Clear Reason. Tourists Are Helping Scientists Understand the Rare Behavior

A trove of photos and videos gathered from social media has helped researchers propose a few possible reasons for the seldom documented action, called “gaping,” including communication, jaw stretching and play

The study focused on brain cell activity in a structure called the hippocampus, which is important for memory and learning.

Is the Unconscious Mind Aware of Its Surroundings? New Research Suggests Anesthetized Brains Can Process Overheard Words

Seven participants had electrodes temporarily implanted in a brain structure important for learning. While anesthetized, their nerve cells learned to differentiate between distinct sounds—and could even predict upcoming words in phrases

This Socorro dove recently hatched at the San Diego Zoo Safari Park. Conservationists have been undertaking a decades-long effort to breed the extinct-in-the-wild species and one day reintroduce it to its native Socorro Island in Mexico.

New, Rare Dove Hatchlings Are a ‘Source of Hope’ for the Extinct-in-the-Wild Birds and a Step Forward in the Ambitious Project to Save Them

The Socorro dove has not been recorded in the wild since 1972, but that could change within only a few years, conservationists say, thanks to a long-term reintroduction effort

Nagatitan chaiyaphumensis was a long-necked, plant-eating dinosaur that lived in what is now Thailand between 100 million and 120 million years ago.

Cool Finds

A Man Spotted Strange-Looking Rocks Near a Pond in Thailand. They Turned Out to Be the Bones of a Massive New Dinosaur Species

Paleontologists have dubbed the long-necked, plant-eating creature “Nagatitan chaiyaphumensis.” It’s the 14th named dinosaur from Thailand, and it might be the biggest one ever found in Southeast Asia

The procedure was likely extremely painful. But, afterward, the Neanderthal continued chewing with the tooth, which suggests they felt some relief.

New Research

Neanderthals Got Cavities, Too—and New Research Suggests They Drilled Into Their Teeth to Treat Them, Just Like Modern Dentists

Researchers unearthed a 59,000-year-old Neanderthal molar that shows signs of dental surgery, a discovery that pushes back the earliest evidence of dental work by roughly 45,000 years

Remoras might dive into manta rays' rear ends when they're scared.

This Fish Hitches Rides in Manta Rays’ ‘Buttholes,’ According to New Research

Scientists suspect that the behavior could harm the manta rays, suggesting a complex relationship between remoras and their hosts that can sometimes be parasitic

The Bering Strait is a narrow waterway between Russia and Alaska that connects the Pacific and Arctic oceans.

Could Building a Dam Across the Bering Strait Save the Planet From Some Effects of Climate Change?

A preliminary study suggests that blocking off the waterway between Russia and Alaska could help the survival of a key system of ocean currents. But there could be potential unforeseen consequences, particularly to marine ecosystems

Laboratory experiments involving pregnant mothers suggest that they can spread yawns to their soon-to-be-born offspring in the womb.

Fetuses Can ‘Catch’ Yawns From Their Mothers While Still in the Womb, New Research Suggests

Yawning is considered a social behavior. Although fetuses were known to yawn, scientists weren’t sure if it was a self-contained reflex or if they could somehow detect cues from their moms

Neanderthals and modern humans have differently shaped skulls, which scientists have long assumed meant they also had different brains. But new research challenges that assumption.

New Research

Did Homo Sapiens Really Outsmart Neanderthals? Different Skull Shapes Didn’t Necessarily Mean Unequal Brain Capacity, New Research Shows

A study from U.S. and Chinese researchers suggests Neanderthals and early modern humans probably had similar cognitive abilities

The Relaxation of Regularly Listening to Songs or Drawing Pictures May Actually Slow Cellular Aging, New Research Shows

According to a new study, people who are exposed to art on a weekly basis are about a year younger “biologically” than those exposed only once or twice per year

This Microscopic Fungus Survived NASA’s Sterilization Protocols—and Is Potentially Hardy Enough to Contaminate Mars

The microbe was gathered from the agency’s clean rooms, where experts build spacecraft in carefully controlled environments. The findings reveal gaps in the agency’s procedures to prevent durable hitchhikers

One-celled algae called diatoms are unique because their cell walls are made of transparent silica, like glass, allowing their internal patterns to be visible. Diatoms are key producers of atmospheric oxygen and uphold the aquatic food chain.
