The Dragon Man skull, described as Homo longi in 2021, belongs to a Denisovan, according to new research.

Iconic ‘Dragon Man’ Skull Offers First Glimpse of What a Denisovan’s Face Looked Like, New Genetic Studies Suggest

The mysterious ancient humans were only known from fossil fragments. Now, two papers argue a skull uncovered in China belongs to this group, after examining preserved DNA and proteins

Bogong moths are brown, nondescript creatures—but scientists now suggest they are the first known invertebrates to use the stars for navigation.

Australian Moths Are the First Known Insects to Navigate by the Stars, Revealing a Migratory Superpower

Bogong moths use both Earth’s magnetic field and the starry night sky to make twice-yearly migrations spanning hundreds of miles, according to new research

Scavengers like turkey vultures remove millions of tons of waste each year by consuming carrion.

Scavenger Animals Are in Trouble, and That Could Spell Bad News for Human Health

More than one-third of species that eat some amount of carrion are threatened or declining, a new analysis finds, and that could lead to a rise in zoonotic diseases

The mosquitoes are dropped from drones inside small, cylindrical, biodegradable containers.

Scientists Are Using Drones to Unleash Thousands of Mosquitoes in Hawaii in a Bid to Save Native Birds. Here’s How It Works

The lab-raised, non-biting male mosquitoes are meant to breed with the invasive ones on the islands and produce sterile eggs that will help suppress avian malaria

Researchers developed a wearable device to monitor participants' breathing.

The Way You Breathe Is Unique to You, Like a Fingerprint, New Study Suggests

Researchers could identify people with almost 97 percent accuracy based on 24 hours of their recorded breathing patterns, and they also found links to a person’s mental and physical condition

In December 2024, a trail camera installed on private property in Oklahoma's Cimarron County photographed an adult mountain lion with three kittens.

Rare Mountain Lion Kittens Spotted on Trail Cameras Suggest the Big Cats May Be Re-establishing a Population in Oklahoma

Two separate adult mountain lions were recorded with cubs in different parts of the state last year, offering the first evidence confirmed by state biologists that the cats could be breeding there

Axolotls are helping scientists understand the key to limb regeneration.

Axolotls May Hold the Key to Regrowing Limbs, and Scientists Are Unraveling Their Secrets to Help Humans Do the Same

With the help of gene-edited axolotls, researchers have gotten one step closer to enabling human limb regeneration

The squid species had only been known from dead specimens found in fishing nets or the stomachs of other animals.

Scientists Had Never Seen This Mysterious Squid Alive in the Wild—Until Now. See the First Footage of the Elusive Creature

A three-foot-long Antarctic gonate squid was spotted swimming 7,000 feet below the surface of the Southern Ocean

Cool Finds

Researchers Discover That Living Worm Towers Exist in Nature, Not Just in Horror Movies

A new study reveals that nematodes assemble into coordinated structures to catch a ride on passersby

A Cape sundew wraps its sticky leaves around a helpless fly.

Carnivorous Plants Have Been Trapping Animals for Millions of Years. So Why Have They Never Grown Larger?

Plants that feed on meat and animal droppings have evolved at least ten times through evolutionary history

Scientists determined the most effective method of halting the disease was covering a coral colony with a weighted plastic bag, then injecting a seawater solution that contains the probiotic. They left the colony covered for two hours to allow the probiotic bacteria to colonize the coral.

A Deadly Disease Is Eating Away at Caribbean Corals and Wreaking Havoc on Reefs. Could Probiotics Be the Solution?

New research suggests the probiotic McH1-7 could help stop the spread of stony coral tissue loss disease among wild corals near Fort Lauderdale, Florida

Crossing roads is a dangerous part of the migratory journey for many amphibians. In Monkton, Vermont, two tunnels beneath a street are helping frogs, salamanders and other creatures reach their destinations safely, according to a new study.

Two Wildlife Tunnels Are Saving Thousands of Amphibians From Being Crushed by Cars in Vermont

New research finds a pair of underpasses installed under a road that crosses a migration corridor have led to an 80.2 percent reduction in amphibian deaths

An artistic reconstruction of the extinct megalodon. Scientists' ideas about how the megalodon looked are based on its fossilized teeth.

The Fearsome Megalodon Ate Basically Whatever It Wanted to Reach Its Daily 100,000-Calorie Need, Study Suggests

Scientists previously assumed the giant, prehistoric sharks mostly feasted on whales, but it turns out they probably weren’t so picky

Researchers revealed that differences in sloth habitats drove the wide variation in size seen in extinct species.

Giant Sloths the Size of Elephants Once Walked Along the Ground. Here’s How the Massive Animals Evolved and Declined

Researchers analyzed fossils and DNA to get a big-picture view of sloth evolution and determine what drove their immense size variation
