As rising temperatures threaten the Arctic mammals, scientists are turning to new, non-invasive methods to study them

Female mosquitoes need to drink blood in order to produce their eggs.

Male Mosquitoes May Have Once Sucked Blood, Amber Fossils Suggest

Today, only female mosquitoes feed on the blood of animals, while males are satisfied with plant juices

'Bone Biographies' Reconstruct Lives of Medieval Cambridge Commoners

Researchers have used skeletal remains to compile information about the lives of ordinary residents of the city

Researchers studied brainstem activity of mice while the animals were awake and eating.

Scientists Examine Brain Cells That Control How Much Mice Eat

The study—the first to look at these neurons while animals are awake and consuming food—could tell us about our own appetites

Brain Implants Show Promise for People With Traumatic Brain Injuries in Small Study

Electrodes placed in the brains of five patients led to "profound" improvements in cognitive function, even years after their injuries

Eczema affects almost 32 million people in the United States.

Here's What Can Cause Itchiness, According to New Research

Scientists discovered a connection between a bacteria linked to eczema and an itch-causing enzyme in a study of mice

Fossilized Trisauropodiscus tracks from more than 210 million years ago (marked with 4 cm scale) compared to modern bird tracks from March 2018 (marked with 3 cm scale)

Mysterious Creatures With Bird-Like Feet Made These Tracks Long Before Birds Evolved

The footprints pre-date the earliest known fossils of avian ancestors by roughly 60 million years, per a new study

A De Winton's golden mole. A member of the species hadn't been definitely seen since 1936.

Scientists Uncover a Golden Mole Species Thought to Be 'Possibly Extinct'

A scent-detecting dog led the team to the discovery in South Africa, and traces of mole DNA helped confirm it

For the inner four planets in this solar system, each planet orbits the sun three times for every two orbits of the planet immediately to its outside. For the fourth, fifth and sixth planets, they orbit four times for every three orbits of its outer neighbor.

Astronomers Discover Rare Solar System Where Planets Orbit in Mathematical Harmony

The "resonant" planets could provide insight about how such systems form and evolve—and why our own solar system is not synced up

German researchers tested dolphins' ability to detect electric fields.

Bottlenose Dolphins May Have an Electric Sense, Study Finds

Dimples called vibrissal pits on the beaks of the mammals can perceive electricity and might help with hunting and navigation

Alice Tate-Harte, a conservator at English Heritage, works on a 17th-century portrait of Diana Cecil.

Conservators removed cosmetic changes made to a painting of English aristocrat Diana Cecil, likely to match 19th-century beauty standards

An artist's rendition of the detection of the cosmic ray by the Telescope Array experiment. When high-energy cosmic rays reach Earth's atmosphere, they collide with and break apart atomic nuclei, creating a shower of particles that is picked up by detectors on the ground.

Scientists Mystified by Rare, High-Energy Cosmic Ray, the Most Powerful Since 1991

Researchers have been unable to locate an obvious source for the particle—it seems to have traveled from an empty spot in space

Researchers studied African penguins in the colony at Zoomarine Italia in Rome.

African Penguins Tell Each Other Apart by Their Polka Dot Patterns

New research suggests the birds may find their mates in crowded colonies by looking at their chest plumage

Researchers at the Ohio State University collected 9,287 Asian longhorned ticks in just 90 minutes using lint rollers.

An Invasive Tick That Can Clone Itself Is Spreading Across the U.S., Threatening Livestock

Researchers documented three cows in Ohio killed by Asian longhorned ticks, which can lay up to 2,000 eggs without needing to mate

Striated caracaras are falcons, but they don't act much like other birds of prey.

These Brainy Falcons Are Smarter Than You Might Think

Striated caracaras solved up to eight puzzle box problems in a new study, suggesting they are cognitively complex, like crows and parrots

When erect, the penises of male serotine bats are seven times longer than female bats' vaginas and seven times wider than the females' vaginal openings.

This Bat Uses Its Extra Long Penis Like an Arm While Mating

Serotine bats are the first mammals known to mate without penetration, new research suggests

Bonobos from different social groups will groom each other and share food.

Like Humans, Some Bonobos Cooperate With Outsiders

We might not be the only primates to display helpful behavior toward members of a different social group, a new study suggests

A candlelit vigil on January 13, 2022, in Washington, D.C., for nurses who died during the Covid-19 pandemic. A new study finds that Covid-19 was the leading reason for a growing gap in life expectancy between U.S. men and women from 2019 to 2021.

Women Now Live Nearly Six Years Longer Than Men in the United States

Disparities from Covid-19 and opioid overdose deaths are major contributors to the widening gap, according to a new study

Green sea turtles are struggling because of climate change, habitat destruction, erosion and other threats.

Metal Pollution May Be Making More Green Sea Turtles Female

In addition to warming temperatures, new research finds contaminants might contribute to the endangered reptiles' skewed sex ratios

Around 40 percent of people experience a fainting spell at some point in their lives.
