A trail camera in Vermont captured 80 photos of moths fluttering around a moose's head, likely slurping up its tears.

Trail Cameras in Vermont Captured Something Strange: Moths Sipping a Moose’s Tears

Tear-drinking, known as lachryphagy, has mostly been observed in the tropics, so scientists were somewhat surprised to find the unusual behavior so far north

A rinkhals (Hemachatus haemachatus) in Hluhluwe, South Africa, performs a threat display. These snakes tend to live on the edges of human communities.

The High-Stakes Quest to Make Snakebites Survivable Took Leaps Forward This Year, With Promising New Avenues to Safer Antivenoms

A wave of fresh science is challenging a century-old treatment and offering hope to the people snakebites harm most—often far from hospitals and help

Orcas and dolphins might hang out together off the coast of British Columbia to hunt for food as a team, new research suggests.

Watch These Orcas Follow Dolphins to Snag a Salmon Feast. It Might Be the First Evidence of These Species Working Together

Off the coast of British Columbia, killer whales are tailing dolphins, and both seem to be rewarded with fishy meals. But not everyone is convinced it’s teamwork—and the behavior may hint at other ocean stressors

Owners and their golden retrievers gather in an attempt to break the world record in the Bosques de Palermo in Buenos Aires on December 8, 2025.

Spotted lanternflies have spread to nearly 20 states since 2014.

Bees Are Turning the Sticky-Sweet Secretions of Spotted Lanternflies Into Honey—and Some People Love the Smoky-Smelling Stuff

The invasive insects have been spreading across the United States for over a decade, leaving behind poop that bees are transforming into a less sweet, sometimes savory, honey

A Laysan albatross checks on its egg.

Stream the Beautiful Highs and Violent Lows of Albatross Life With This New 24-Hour Camera on Midway Atoll

You can see the large white seabirds dancing, preening, feeding and raising young—though the live feed might show a dark side of island living, too, with potential predation from invasive mice

Juvenile sunflower sea stars at the Sunflower Star Laboratory in Moss Landing, California. At this phase, each is less than an inch wide, but they can grow to be more than three feet across as adults.

A Deadly Pathogen Decimated Sunflower Sea Stars. Look Inside the Lab Working to Bring Them Back by Freezing and Thawing Their Larvae

For the first time, scientists have cryopreserved and revived the larvae of a sea star species. The breakthrough, made with the giant pink star, gives hope the technique could be repeated to save the imperiled predator

Excess weight can harm a cat's quality of life and exacerbate health conditions.

Can GLP-1s Help Fat Cats Lose Weight? The First Clinical Trial Testing the Drugs for Weight Loss in Felines Has Begun

San Francisco-based pharmaceutical company OKAVA is investigating an implant that slowly releases a GLP-1 medication for up to six months

A Trove of Sea Cow Fossils in Qatar Reveals a New Species That Munched on Seagrass 21 Million Years Ago

The findings suggest that sea cows have been engineering ecosystems in the Persian Gulf for tens of millions of years

In a new study, 79 percent of black-spotted pond frogs successfully consumed the northern giant hornet.

Claude lived at the California Academy of Sciences for 17 years and became a beloved celebrity.

Claude, San Francisco’s Beloved Albino Alligator and ‘Unofficial Mascot,’ Dies at Age 30

Veterinarians will conduct a full exam and necropsy to determine the cause of death, but Claude had been undergoing treatment for a suspected infection in recent weeks

For the study, the researchers worked with two adult male macaques that had previously been trained to tap in time with a metronome.

These Monkeys Learned to Tap to the Beat of the Backstreet Boys. Can They Teach Researchers About the Origins of Human Musicality?

Two macaques learned to keep time with various songs, which might point to how humans got their sense of rhythm. But some scientists doubt that the primates’ feat, which required extensive instruction, can give evolutionary clues
