Pygmy raccoons live only on Mexico's Cozumel Island.

These Adorable, Critically Endangered Pygmy Raccoons in Cozumel Are Teaching One Another to Turn Trash Into Toy Balls

The observations offer rare evidence of a skill being passed among raccoons. But the work also highlights the effects of human pollution at the popular tourist destination

Since calorie restriction is known to slow aging, researchers wanted to know if GLP-1s—which curb appetite—could do the same.

GLP-1 Weight-Loss Drugs Can Slow Aging and Extend Life Span, Mouse Study Suggests

Older female mice—equivalent in age to 60-year-old women—given daily injections of the active ingredient in Ozempic lived about 12 percent longer than animals that didn’t receive the drug

The Golden Gate Bridge in San Francisco is coated in a protective paint called International Orange.

Why Does Rain Eat Through Protective Coatings on Metal Structures? Researchers Propose a New Idea: Electrically Charged Droplets

Scientists long attributed rain damage to physical abrasion and chemical degradation from acidic substances. A new study offers a third idea, which could help researchers develop longer-lasting coatings and preserve important objects

While no prediction tool is 100 percent accurate, experts have developed interactive maps to guide your leaf-peeping activities.

Leaf-Peeping Season Is Almost Here. These Interactive Maps Can Help You Figure Out When Fall Foliage Will Peak in Your Area

From the magnificent mountains of New England to the desert landscape of northern New Mexico, the tools can help you make the most of nature’s upcoming wardrobe change

Scientists Just Learned That This Bat Eats Birds Midflight. A Renaissance Painter May Have Known About It Hundreds of Years Ago

Last fall, scientists reported the first known recordings of greater noctule bats hunting and feasting on songbirds during night flights. But a 17th-century artwork by Jan Brueghel the Elder seems to depict the species flying with feathered prey in its mouth

Scientists Say They’ve Made Cells That Feed, Grow and Reproduce, Bringing Them One Step Closer to Building Life From Scratch

The human-made cells show many hallmarks of life, but they can’t make all their necessary internal structures or divide for very many generations

Researchers came up with the new count by studying insect biodiversity in a conservation area in Costa Rica.

Earth Might Be Home to 20 Million Insect Species—More Than Three Times as Many as Previously Thought, a Study Suggests

Recent estimates have come to the consensus that our planet hosts roughly six million species. But new research reveals that those counts may be drastically underestimated

A time-lapse of an individual D. melanogaster sperm cell. The head is artificially colored pink, and the tail is teal.

These Male Fruit Flies Have Sperm That Are Nearly as Long as Their Bodies. Here’s How the Cells Don’t Become a Tangled Mess

Males of the species Drosophila melanogaster pack thousands of almost two-millimeter-long sperm cells into significantly smaller storage organs. A new study reveals how they move in an orderly manner

The bone was collected in December 1985 by the late geologist Mike Thomson, who described it as a "vertebra of large reptile" in his field notebook.

A Fossil From Antarctica Sat in a Drawer for 40 Years. It Turned Out to Be the First Dinosaur Bone Ever Found on the Continent

After being forgotten for decades, the mysterious tail vertebra has finally been identified as part of a titanosaur. The discovery helps researchers understand how dinosaurs may have traversed Earth’s southernmost regions
