Common vampire bat

When Vampire Bats Become Close Friends, They Start ‘Talking’ Like Each Other

New research shows that just like humans, vampire bats with deep social relationships use similar sounds as one another to communicate

After capturing the 77-pound male, wildlife officials said they planned to re-collar and release the creature into the wild.

Wildlife officials successfully captured the young male, known as 157M, after he wandered into the northern Pacific Heights neighborhood

A Brazilian keelback (Helicops infrataeniatus) cannibalizes another in 2015.

Cannibalism Among Snakes Is Far More Widespread Than Previously Thought

Scientists undertook the first comprehensive assessment of how often snakes eat their own, uncovering reports of the behavior in more than 200 species

Outbreaks of crown-of-thorns starfish have threatened the Great Barrier Reef since the 1960s.

These Hungry Starfish Are Spiraling Out of Control in Australia. Now Scientists Say They Have a New Plan to Fight Back

Synthetic pheromones may be a promising tool in attracting and culling troublesome crown-of-thorns starfish, which rapidly eat large amounts of coral on the Great Barrier Reef

Common big-eared bats eat relatively large insects, such as katydids.

A Robot Is Unraveling the Secrets of How Some Bats Bounce Sound Waves Off Leaves to Find Insect Prey

A new study from the Smithsonian Tropical Research Institute used a robot to mimic common big-eared bats’ echolocation skills

In “Depicting Dark Waters,” British sculptural model maker Alice Baker collaborated with marine biologists from the Netherlands and Sweden to depict European cold-water corals in glass and raise awareness about deep-sea ecosystems.

Art Meets Science

The Hidden World of Cold-Water Corals Rises to the Surface With These Glass Sculptures That Are Resurrecting a Lost Craft

As increased industrial activity puts fragile deep-sea ecosystems at risk, one artist is raising awareness about imperiled corals through scientific model making

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

Crabs not yet at the molting stage are thrown back into the Venice lagoon.

Coastal Cities of Europe

Can Venice’s Iconic Crab Dish Survive Climate Change?

For more than 300 years, Italians have fried soft-shell green crabs, called moeche. But the culinary tradition is under threat

Many stingless bees are native to Peru, where they pollinate the Amazon's diverse plants and food crops.

Honey-Making Stingless Bees in the Peruvian Amazon Become the First Insects to Gain Legal Rights

Two local ordinances granted rights to at least 175 stingless bee species in Peru, which are culturally and spiritually significant to Indigenous peoples and help maintain a healthy rainforest ecosystem

Dark-eyed juncos are small sparrows found throughout North America.

These Urban Birds Evolved Longer Beaks During Covid-19 Lockdowns. Then, They Changed Back

Researchers suspect that dark-eyed juncos living in Los Angeles adapted based on the availability of food scraps tossed by humans

The researchers examined 3D reconstructions of hundreds of ant exoskeletons.

Some Ants Sacrifice Stronger Exoskeletons for Larger Colonies, Which May Help Them Take Over New Environments

Species with thinner protective barriers may need fewer resources and tend to have a greater ability to adapt to new habitats, a study suggests

These Male Hummingbirds Evolved Straighter, Sharper Bills So They Could Better Joust for Mates

While female green hermit hummingbirds have curved bills, males’ straighter mouthparts are built for stabbing one another, a new study suggests

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

The reproductive structures of cycads, an ancient seed plant, heat up with infrared radiation to attract beetle pollinators, a new study suggests. 

Cool Finds

Before the First Brilliantly Colored Flowers Bloomed, Dinosaur-Era Plants Emitted Heat to Attract Pollinators

Some plants produce heat, which has long puzzled botanists. But a new study suggests that infrared radiation is an ancient method to lure beetle pollinators

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

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

‘Murder Hornets’ Might Strike Terror in Humans, but These Frogs Can Eat Them for Lunch

Watch a pond frog effortlessly devour the northern giant hornet, the largest hornet in the world, while sustaining stings that are deadly to many animals

A savanna in western Maharashtra, India

Ancient Literature Suggests India’s Savannas Are Much Older Than Previously Thought

Plant species mentioned in texts from the past 800 years hint the wooded grasslands of western India have been there since ancient times, pushing back on the narrative that they are remnants of long-gone forests

A raccoon peers out from a tree. New research suggests urban raccoons in the United States have shorter snouts than rural raccoons do, a sign of potential domestication.

Urban Raccoons Are Showing Signs of Early Domestication, With Shorter Snouts Than Their Rural Cousins

The shorter faces of these city-dwelling trash bandits offer a telltale sign of domestication and line up with a leading hypothesis about animals that adapt to human-dominated environments, according to a new study

The black parasitic ant tricks the workers into attacking their amber queen.

These Parasitic Ant Queens Found a Sneaky Way to Stage a Coup: Trick a Colony Into Killing its Mother

While ant queen violence is well-known, scientists recently documented the first evidence of parasite-induced matricide

The Palos Verdes Kelp Forest Restoration Project near Los Angeles forms an ecosystem that is home to many creatures.

Underwater Forests Return to Life off the Coast of California, and That Might be Good News for the Entire Planet

Wondrous kelp beds harbor a complex ecosystem that’s teeming with life, cleaning the water and the atmosphere, and bringing new hope for the future
