The pet cow’s tool use challenges long-held assumptions about bovine intelligence

A reconstruction of what Manipulonyx reshetovi may have looked like

This Dinosaur May Have Used Its Strange Clawed Hands to Pilfer and Pierce Eggs

A fresh analysis of a fossil found almost 50 years ago reveals a newly described genus named for its “manipulating claw”

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

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

The "Tumat puppies" were discovered with their fur, skin and stomach contents still intact.

Contents of a Wolf Pup’s Stomach From 14,400 Years Ago Are Teaching Researchers About the Lives of the Last Woolly Rhinos

Analysis of woolly rhinoceros DNA recovered from the permafrost-preserved wolf further hints that the Ice Age beasts went extinct because of a sudden shift in the climate

Dealing with centuries of darkness and eye parasites doesn't seem to affect Greenland sharks' vision.

Greenland Sharks Can Survive for Centuries—and Maintain Long-Lasting Vision, Despite Living in the Dark

The long-living sharks aren’t as blind as once thought and have DNA repair mechanisms that may help prevent their vision from degrading, a study suggests

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

Researchers were shocked to find a shock wave around a dead star. 

This Mysterious Gas Cloud Spotted Around a Dead Star Is Beautiful—but Astronomers Say It Shouldn’t Be There

The stellar corpse is spewing star stuff, which is heating and compressing surrounding gas, resulting in a multicolored display. But it’s missing a component thought to be necessary for this phenomenon

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

Same-sex behaviors seem to be common among rhesus macaques.

Biologists Reveal How Same-Sex Sexual Behavior May Have Given Some Primates an Evolutionary Advantage

Nonhuman primates like bonobos and chimpanzees might engage in same-sex sexual activities to strengthen bonds, particularly in harsh environments or within strict social structures, a new study suggests

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.

New Research

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
