Ötzi the Iceman is housed at the South Tyrol Museum of Archaeology, where conservationists periodically humidify his remains.

Ötzi the Iceman May Have Carried a Cancer-Causing Strain of HPV, a Common Virus Still Plaguing Humans Today

A new study, which also found evidence of the high-risk strain in 45,000-year-old remains, suggests HPV has evolved alongside humans for many millennia

Some solutions are reached incrementally, with logic or calculations. But others seem to just pop into your head—and neuroscientists are investigating how this happens.

‘Aha’ Moments Seem to Come Out of Nowhere. How Does the Brain Create These Sudden Bursts of Insight?

Neuroscientists are tracking the brain activity that underlies a cognitive breakthrough and unraveling how it might boost memory

Researchers investigated Pompeii's water system, including the "water castle" pictured here, which served as the water distribution structure for Pompeii's aqueduct. 

New Research

The Public Baths of Ancient Pompeii Were Actually Pretty Gross—Until the Romans Built an Aqueduct

Hygienic conditions were poor in the city’s older bathing facilities, a new study reveals. The analysis sheds light on Pompeii’s water systems and residents’ bathing habits

Europa, one of Jupiter's moons

Jupiter’s Moon Europa Is a Top Candidate for Hosting Alien Life. But It May Lack the Geologic Activity Needed to Birth Microbes

On Earth, deep-sea vents may have given rise to the planet’s first life. But nothing of the sort seems to be happening at the bottom of Europa’s ocean, a study suggests

Spaceflight Temporarily Changes the Position and Shape of Astronauts’ Brains, MRI Data Suggests

The biggest changes happen in brain regions involved with processing sensory information and coordinating movement, according to a new study

A worker bee (left) and a queen bee (right) slurp up artificial nectar during laboratory experiments.

Queen Bumblebees’ Tongues Aren’t Built for Slurping Nectar—Which Might Keep the Royals Homebound

Queen bumblebees have sparser hair on their tongues than worker bees, which makes them less efficient at lapping up nectar, new research suggests

A neural circuit that processes motivation and reward seems to act as a "brake" when faced with an unpleasant task, a study suggests.

Can’t Get Started on a Daunting Task? This Brain Circuit That Slams the Brakes on Motivation Might Be to Blame

Monkey experiments hint at a “motivation brake” pathway between two brain regions. Manipulating it may lead to new treatments for depression and other psychiatric conditions

Cloud-9, shown in magenta. The circle represents the region where researchers focused their search for stars—the peak of radio emission.

Astronomers Find an Odd Space Cloud, Like a Galaxy Without Stars, That Could Shed Light on the Secrets of Dark Matter

Named “Cloud-9,” the discovery is a new type of celestial object known as a RELHIC, which is unlike anything scientists have ever observed

Naked mole-rats are unusual for their long lives and resistance to cancer. Now, researchers suggest the rodents not only tolerate but prefer to be in low-oxygen air.

Naked Mole-Rats Prefer Low-Oxygen Air That Would Kill Most Mammals, Adding to Their List of Death-Defying Superpowers

These underground rodents are the first mammals found to actively choose air with lower-than-normal oxygen levels. Their remarkable ability to survive these conditions could offer a key model for researchers studying new treatments for stroke or lung diseases in humans

Though the study describes only a correlational relationship, the findings reinforce the idea that sleep is important for human health. 

Not Getting Enough Sleep? You Might Be Shortening Your Life Span

In the United States, insufficient sleep strongly correlates with life expectancy, even more than diet, exercise or social connections do, a new study suggests

Researchers investigated the associations between preservatives and the risk of developing cancer and type 2 diabetes.

Eating Large Amounts of Certain Preservatives Might Increase Your Risk of Developing Cancer and Type 2 Diabetes

Two studies tracked more than 100,000 participants over 14 years to reveal the trends. But they can’t confirm a direct link between eating these preservatives and developing disease, especially because some of the additives were eaten in foods that contain known carcinogens

The study involved pups like Miso, a 6-year-old male border collie from Canada who knows the names of about 200 toys.

Some Dogs Are ‘Gifted Word Learners’ That Learn Language by Eavesdropping—Just Like Human Toddlers

New research suggests prodigious pups that already have large vocabularies can learn new words by listening in on their owners’ conversations

Some octopuses have incredible camouflaging abilities. 

Inspired by Octopus Skin, This Synthetic Material Can Change Color and Texture on Demand

The animals’ camouflaging capabilities have long inspired humans. The new material could one day help researchers improve robotics or electronic screens

Five quartz arrowheads unearthed in South Africa contained traces of toxins.

Cool Finds

Archaeologists Just Discovered the Oldest Known Evidence of Poison Arrows, Which Hunters Used to Slow Down Their Prey 60,000 Years Ago

New research reveals traces of plant toxins on arrow tips in South Africa, suggesting that the technique was used tens of thousands of years earlier than scientists thought

Brainless upside-down jellyfish, like this one in its natural habitat near Eilat, Israel, spend about one-third of their time asleep.

Even Though They Don’t Have Brains to Rest, Jellyfish and Sea Anemones Sleep Like Humans

Sleep may have evolved to help reduce DNA damage in nerve cells long before they became centralized in the brain, a study suggests

A written description (left) of New Zealand flax (illustrated on the right) references an Indigenous name for the plant: “haragag.”

Newly Digitized Records Reveal How Indigenous People Shared Their Knowledge of New Zealand’s Plants With Captain Cook’s Crew

Long-overlooked documents housed at London’s Natural History Museum testify to the exchange of information between 18th-century European botanists and their Indigenous counterparts

Male white-tailed deer rub their heads on trees and urinate on scraped-up earth to leave "signposts," which glow under ultraviolet light, a study suggests.

When Male Deer Mark Trees, Those Spots May Glow Like Neon Lights at Dusk and Dawn, Though Humans Usually Can’t See Them

During the breeding season, white-tailed deer might use their eyes and noses to navigate signs—forehead secretions on trees and urine on the ground—left by males of their species, a study suggests

Cool Finds

This Early-Universe Cluster of Galaxies Is Way Hotter Than It Should Be

Gas within the cluster, which existed merely 1.4 billion years after the Big Bang, is at least five times hotter than computer simulations predict it should be, a study suggests

New Fossil Analysis Suggests This Seven-Million-Year-Old Primate Walked on Two Legs, Potentially Making It the Oldest Known Human Ancestor

Fresh findings about arm and leg bones advance the debate over whether Sahelanthropus tchadensis was bipedal, but not everyone is convinced

Divers visited the site between 2022 and 2024.

Archaeologists Discover Mysterious 7,000-Year-Old Stone Wall Beneath the Waves Off the Coast of France

The sturdy, well-built structure was likely constructed on dry land at a time when sea levels were much lower than they are today
