Lab-made cosmic dust on a chip

Physicists Create Homemade Cosmic Dust, Which Could Help Them Figure Out How the Building Blocks of Life First Reached Earth

Cosmic dust normally comes from dying stars. The recipe for a lab-made version includes a few gases, vacuum tubes and electricity

New life may have evolved surprisingly fast after a famous mass extinction event about 66 million years ago.

After the Dinosaur-Killing Asteroid Wrecked the Planet, Life May Have Bounced Back Surprisingly Fast

The steady rate of falling space dust helped researchers recalibrate the timeline

After exposing an ant to the air pollutant ozone, its nestmates acted aggressively toward it.

Air Pollution Can Cause Some Ants to Turn on One Another—and Neglect Their Young, New Research Suggests

The findings further hint that air pollution, particularly ozone, is contributing to the “insect apocalypse”

Cool Finds

The Earliest Known Vertebrates Had Four Eyes—and They Worked a Lot Like Ours Do, New Research Suggests

Two of those eyes may have evolved into a part of the brain called the pineal gland

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

Ice can take on more than 20 forms, or phases, depending on the temperature and pressure conditions as water crystallizes.

Researchers Discover a New Phase of Ice by Squeezing Water Between Diamonds

The new form, called Ice XXI, appeared at room temperature in the lab, and it may have a similar density to ice on distant moons in our solar system

An illustration of a member of the Prototaxites genus, which lived between 420 million and 375 million years ago

This Mysterious 407-Million-Year-Old Fossil May Represent a Previously Unknown Branch of Life

Earth’s first large land organisms—tree trunk-like beings that stood up to 26 feet tall—weren’t early fungi but, rather, something else entirely, a study suggests

A "bar" of iron atoms, colored red in this image, has been hiding inside the Ring Nebula.

Cool Finds

Astronomers Discover a Mysterious Bar-Shaped Cloud of Iron Within the Iconic Ring Nebula

Humans have been eyeing the colorful Ring Nebula for nearly 250 years, but testing out a new telescope tool led to the perplexing finding

Researchers investigated Pompeii's water system, including the "water castle" pictured here, which served as the water distribution structure for Pompeii's aqueduct. 

New Research

The Public Baths of Ancient Pompeii Were Actually Pretty Gross—Until the Romans Built an Aqueduct

Hygienic conditions were poor in the city’s older bathing facilities, a new study reveals. The analysis sheds light on Pompeii’s water systems and residents’ bathing habits

Some octopuses have incredible camouflaging abilities. 

Inspired by Octopus Skin, This Synthetic Material Can Change Color and Texture on Demand

The animals’ camouflaging capabilities have long inspired humans. The new material could one day help researchers improve robotics or electronic screens

This Lemon-Shaped Planet Has an Atmosphere Unlike Anything Astronomers Have Ever Seen

The James Webb Space Telescope detected an atmosphere rich with carbon and helium, which is unexpected on this hot planet roughly 2,000 light-years from Earth

Research indicates that coral reefs have been tuning Earth's cycles for hundreds of millions of years. 

For More Than 250 Million Years, Coral Reefs Have Had a Major Influence on Earth’s Changing Climate

The planet has been flipping between two main modes of carbon recovery depending on the state of coral reefs, new research suggests

Researchers used more than 400 samples of materials, such as this carbon-rich substance, to train and test the new A.I. system. 

Cool Finds

A.I. Reveals Signs of Early Life in 3.3-Billion-Year-Old Rocks. Next, It Could Continue the Search in Space

The new approach looks at the distribution of molecular fragments in material, allowing for broad surveys in degraded specimens

Six species of North American bats—big brown bats (pictured), eastern red bats, Seminole bats, southeastern myotis, gray bats and Brazilian free-tailed bats—glow green under ultraviolet light, new research shows.

These Bats Glow Green Under UV Light, Joining a Growing List of Photoluminescent Mammals

A recent study identifies a consistent glow across six species of North American bats, but the underlying reason for the animals’ green gleam is still unclear

Psilocybe cubensis, a mushroom that produces the psychoactive compound psilocybin.

Magic Mushrooms Evolved Psilocybin Not Once, but Twice

Two different types of mushroom evolved the same psychedelic compound in completely unrelated ways, a recent study finds

Members of the Nobel Committee for Chemistry hold a model of a metal-organic framework during the 2025 prize announcement in Stockholm on October 8.

Architects of a New Kind of Molecular Structure Win Nobel Prize in Chemistry

Metal-organic frameworks can store huge amounts of gas in a tiny space—enabling advances that could help humans fight climate change and tackle other challenges

Conness Glacier.

New Research

By 2100, Humans Might See a Glacier-Free Sierra Nevada for the First Time Ever

A new study suggests some glaciers have existed on the California mountain range for the entirety of known human history in North America

Scientists Finally Found Phosphine on a Brown Dwarf. Here’s What That Means for the Search for Extraterrestrial Life

The detection could force astronomers to reconsider their chemical models

Saturn’s E ring contains grains of water ice from the underground ocean on its moon Enceladus.

Decades-Old Data From Saturn’s Moon Enceladus Hints at Favorable Conditions for Life

The Cassini spacecraft flew by the small, icy moon in 2008, collecting information that suggests it shoots out molecules that could enable life

Smoke from wildfires can cause off-putting, ashy flavors in wine.

Wildfires Are Ruining Your Favorite Wines. These Bacteria Might Be Able to Help

Microbes already growing on grape plants may help neutralize one of the compounds responsible for wildfire-exposed grapes’ off-putting flavors, new research suggests
