An estimated one million to two million petroglyphs are spread across the Burrup Peninsula and the Dampier Archipelago, in the Pilbara region of Western Australia.

Historical Pollution, Not Current Industrial Emissions, Damaged the World’s Largest and Oldest Collection of Ancient Rock Art, Study Suggests

Researchers say that past exposure to sulfur dioxide is likely to blame for the increased porosity of the Murujuga rock art created by the Ngarda-Ngarli people tens of thousands of years ago

Many stars orbit the Milky Way's central supermassive black hole. But S301's orbit, shown in red, is the only one known to be close enough to feel the effects of the black hole's theorized spin.

This Star Orbits Our Galaxy’s Heart at a Record-Breaking Speed—and Could Help Uncover Secrets About the Behemoth Black Hole There

The speedster travels at up to 56 million miles per hour, or about 8 percent the speed of light. It also gets very close to the supermassive black hole at the center of the Milky Way

Researchers observed bearded capuchins in Brazil eating birds (shown here), lizards, rodents, opossums, snakes and other small vertebrates.

When Fruit Is Scarce, These Monkeys Hunt Animals. The Behavior May Offer Clues About the Origins of Humans’ Meat-Eating Habits

The bearded capuchins of northeastern Brazil typically eat plant-based foods, but they turn to small vertebrates when those sources are limited. Our ancestors may have done the same, eventually allowing predatory behaviors to be more frequently passed on in our lineage

The studied species, brown-lipped snails, are native to Europe.

Snails Can Make Their Slime Sticky, Slippery, Foamy or Hard Depending on Their Needs. Here’s How They Tweak Their Multipurpose Mucus

The critters can alter the proportions of calcium and collagen in the versatile substance, which changes the protein structure. The different textures can help snails glide, climb or protect themselves

Paleontologists Discover a New Species of Ice Age Toad at the La Brea Tar Pits, Offering Clues About the Area’s Ancient Climate

The fossilized remains, recovered in 1929, were part of La Brea’s relatively understudied amphibian collection. Since toads are cold-blooded and sensitive to environmental changes, the discovery can help researchers piece together past climate conditions

CTE is believed to be caused by repeated head injuries.

At Least One in Four Former NFL Players Who Died Between 2016 and 2021 Had the Progressive Brain Disease CTE, Study Suggests

The true prevalence of the neurodegenerative disease—which is associated with repeated head injuries—among the deceased football players might be much higher. CTE affects other athletes too, including hockey players, soccer players and wrestlers

The deep partial lunar eclipse will peak on August 28 at 12:13 a.m. Eastern time.

Turn Your Eyes to the Night Skies This Week to See a Near-Total Lunar Eclipse. It’ll Temporarily Turn the Moon Red

During the peak, 96 percent of the moon will be within the darkest part of our planet’s shadow. The orb will take on an eerie glow because of how sunlight gets filtered through Earth’s atmosphere

This might be the view a seal gets as it comes up from underwater to breathe: a polar bear, looking down for its prey.

See 16 Stunning Animal Images From the Wildlife Photographer of the Year Awards

Now in its 62nd year, the famed competition has released a sneak peek of the entries from this contest ahead of announcing the winners in October

An American bullfrog, which is the largest frog species in North America

This Deadly Shellfish Poisoning Has No Antidote. A Protein Found in American Bullfrogs Could Change That

A study in mice found that a protein called saxiphilin acts like a sponge against a deadly toxin produced by algal blooms. The harmful agent, which accumulates in certain seafood, can cause a life-threatening illness called paralytic shellfish poisoning

A New Telescope Still Under Construction Accidentally Reveals How a Dying Star Returns Matter to Space

Researchers captured an unprecedented image of the stellar recycling process while calibrating a Chile-based instrument called MOTHRA, which is expected to be complete by the end of 2026

‘Hunger Stones’ Resurface in Europe, Bringing Centuries-Old Warnings Back Into View as Rivers Hit Historic Lows

As drought exposes stretches of riverbed in central Europe, markers carved by past generations to record low water levels are emerging once again

Marmots can spend up to eight months in hibernation, so packing on the pounds during the short alpine summer is essential to their survival.

Cast Your Vote for the Chunkiest Alpine Rodent During Colorado’s First-Ever Fat Marmot Week

The inaugural competition puts eight yellow-bellied marmots head-to-head while shining a light on the science behind their seasonal weight gain and survival at high elevations

A long-clawed shrew seen in northern Japan

These Tiny Shrews Grow Bigger Snouts and Shrink Their Brains to Survive Harsh Winters, Study Suggests

Scientists have long known that some small mammals reduce their brain size during cold months and regrow them in the spring. Long-clawed shrews from Hokkaido, Japan, seem to follow that pattern—while their noses surprisingly do the opposite

The Huashan rock art is spread across more than 80 sites spanning roughly 160 miles.

This Rock Art in China Has Remained Bright Red for Nearly 2,000 Years. How? The Secret Ingredient Might Be Blood

A new study offers clues about how the Luoyue people created rock paintings in what’s now southern China. The murals have somehow been durable enough to withstand rain, heat, wind and humidity for centuries

Claude Monet lived in Giverny, a small village about 50 miles northwest of Paris, for more than four decades.

In France, Brutal Summer Heat Waves Are Taking a Toll on the Flowers That Inspired Claude Monet’s Most Beloved Paintings

The colorful nasturtiums at the artist’s house and gardens have been hit particularly hard this summer as France grapples with a record 52 heatwave days

In Pompano Beach, a museum dedicated entirely to jellyfish has recently opened its doors. 

‘Only One of Its Kind’ Jellyfish Museum Astounds Visitors With Awe-Inspiring Displays of Sea Nettles Safely Behind Glass

The museum opened in the spring and was founded by two aquarium experts who fled the Russia-Ukraine war

The team combined two operating tables to hold the snake's lengthy 110-pound body.

This 15-Foot Python Is the First Known Snake to Receive Electrochemotherapy for Cancer. Now, She’s Officially Free of the Disease

The pioneering treatment makes it easier for traditional chemotherapy drugs to penetrate cancer cells. After the procedure, the reptile, named Jodie Foster, made a speedy recovery

Scientists used Evo, an AI tool that can suggest genome designs, to design new viruses. 

Scientists Used A.I. to Design New Viruses. The Technology Could Be a Boon for Medicine, but Experts Worry About Harmful Pathogens

The findings represent the first genomes, or complete genetic instruction books, designed entirely with generative A.I. The resulting viruses attack only bacteria, which could one day help overcome the problem of antibiotic-resistant microbes

The trial only included people with melanoma, but experts say the same treatment approach could potentially be applied more broadly—to other types of cancer, as well as rare conditions caused by genetic mutations.

A New Personalized Cancer Vaccine Could Keep Skin Cancer From Coming Back, Drugmakers Say

The results, announced this week by Moderna and Merck, could pave the way for a new generation of treatments tailored to individual tumors

The researchers trained pet dogs to sit still during an MRI scan.

Scientists Gave Dogs MRIs and Learned That They’re Surprisingly Good at Distinguishing Between Human Emotions, Even Some Negative Ones

A recent study found that man’s best friend processes positive and negative human emotions differently and can distinguish between fearful faces and those showing sadness or anger
