The ghostly phenomenon could be the product of a chemical reaction involving methane, researchers suggest

The newly identified tektites.

Cool Finds

Researchers Find Evidence of a Mysterious Giant Asteroid Impact, but They Don’t Know Where Its Crater Is

Special shards of glass, known as “tektites,” were hiding in plain sight in a museum collection

Researchers directly dated dinosaur eggs, which had filled with calcite crystals, in China.

Paleontologists Directly Date Dinosaur Eggs for the First Time, Shedding Light on the Cretaceous World 85 Million Years Ago

Using uranium-lead dating, researchers calculated the age of the eggs, rather than the sediments around them, at the Qinglongshan site in China

Some of the barrels off the coast of Los Angeles are surrounded by mysterious white halos in the sediment.

Metal Barrels Dumped Off the Coast of Los Angeles Are Encircled by Mysterious White Halos—and Scientists Think They Finally Know Why

At least some of the barrels contain caustic alkaline waste, which has made the surrounding ecosystems inhospitable to most life forms, a new study suggests

The dwarf planet Ceres, the only dwarf planet in the main asteroid belt, might have once been hospitable for life, according to a recent study.

Did the Dwarf Planet Ceres Once Host Life? Astronomers Suggest Chemical Energy Could Have Fueled Microbes Long Ago

Though no direct evidence of life has been found, models suggest Ceres had hot water shooting into its underground oceans billions of years ago, offering potentially hospitable conditions

The research team's glowing succulents, which lit up in shades of red, green and blue

Researchers Create Rechargeable, Glow-in-the-Dark Succulents

The team hopes their work, which is still in the early phases, might one day build the foundation for a novel sustainable lighting system

The Hubble Space Telescope captured this image of 3I/ATLAS with its Wide Field Camera 3.

Telescopes Reveal Surprising Chemistry of a Rare Interstellar Object Passing Through Our Solar System

Called 3I/ATLAS, the object is only the third of its kind known to astronomers, and it’s likely been heading our way for billions of years, carrying pristine material from another star system

Researchers have developed a new, artificial supplement that can deliver crucial nutrients known as sterols to honeybee colonies and promote survival of larvae.

Researchers Develop a ‘Superfood’ for Honeybees to Fight the Drastic Decline of Their Colonies

Bees fed an enriched yeast supplement saw 15 times more of their larvae reach the developmental stage right before adulthood, according to a new study

Stonehenge at sunset. Construction of the iconic stone circle began around 3000 B.C.E. and continued in several phases.

A Neolithic Cow’s Tooth Helps Point to the Mysterious Origins of Stonehenge’s Iconic Stones

Isotope analysis of a molar from a cow’s jawbone found buried at the monument provides details of the life story of the animal—and how it may relate to the construction of Stonehenge

The khipu examined in the study, found to be made with a primary cord of human hair

A Lock of Braided Human Hair Could Change How We Think About Inca Society and Record-Keeping

The khipu knot-tying system was thought to have only been used by elites, but one artifact suggests commoners, too, knew how to use it

Researchers investigated the Mesozoic Era's atmosphere and vegetation by studying oxygen isotopes in dinosaur tooth enamel. This is a replica of a Stan™ T. rex tooth.

Dinosaur Teeth Provide Key Clues to Earth’s Climate Past, Revealing High Levels of Carbon Dioxide

A new study finds that the Mesozoic Era saw significantly higher quantities of the greenhouse gas than both pre-industrial and modern levels, likely due to volcanic activity

New research suggests Neanderthals ate rotten flesh and maggots, explaining why the levels of nitrogen-15 found in their remains are so high.

Neanderthals Might Have Eaten Maggot-Infested, Putrefying Meat, Explaining a Mysterious Chemical Signature in Their Remains

Maggots might have helped our long-extinct relatives avoid protein poisoning by providing a nutritious source of fat, a new study suggests

In the 1950s, archaeologists found bronze jars in an underground shrine (left). They contained a mysterious sticky residue (right).

Scientists Found Sticky Goo Inside a 2,500-Year-Old Jar. Seventy Years Later, They Finally Know What It Is

By studying the mysterious substance’s chemical makeup, scientists determined the pot was once full of honey

Researchers discover the secret behind Burmese pythons' ability to fully digest the bones of their prey.

Researchers Discover the Trick That Allows Burmese Pythons to Digest the Bones of Their Prey

Special intestinal cells collect excess minerals into particles the snakes can poop out, according to a new study

Scientists are investigating the production of ancestral alkaloids by tomatoes in the Galápagos Islands.

Something Strange Is Happening to Tomatoes Growing on the Galápagos Islands

Scientists say wild tomato plants on the archipelago’s western islands are experiencing “reverse evolution” and reverting back to ancestral traits

Scientists determined the most effective method of halting the disease was covering a coral colony with a weighted plastic bag, then injecting a seawater solution that contains the probiotic. They left the colony covered for two hours to allow the probiotic bacteria to colonize the coral.

A Deadly Disease Is Eating Away at Caribbean Corals and Wreaking Havoc on Reefs. Could Probiotics Be the Solution?

New research suggests the probiotic McH1-7 could help stop the spread of stony coral tissue loss disease among wild corals near Fort Lauderdale, Florida

Water may have arisen as early as 100 million years after the universe began.

Did Water Form in the Earliest Years of the Universe?

A recent study suggests huge volumes of the molecule emerged during the cosmic dawn

An artistic rendering of a magnetar—or highly magnetized neutron star—losing material into space. The magnetic field lines, shown in green, direct the movement of charged material.

Astrophysicists Track Down the Mysterious Cosmic Origins of Gold and Other Heavy Metals in Our Galaxy

Researchers suggest powerful bursts from magnetars—collapsed stars with strong magnetic fields—may have contributed up to 10 percent of all elements heavier than iron in the Milky Way

Italian researchers have devised a scientific recipe to get cacio e pepe right every time.

Researchers Have the Perfect Cacio e Pepe Recipe Down to a Science—Literally

Cooking the famous, creamy pasta sauce is as delicious as it is frustrating, because the cheese tends to clump when exposed to heat. That’s why Italian scientists created a new technique that’s “simple yet precise”

An artist's concept of K2-18b, the exoplanet at the center of the debate

A New Analysis Raises Doubts About Potential Hints of Life Recently Detected on a Distant Exoplanet

Astronomers published evidence of possible biosignatures on the planet K2-18b earlier this month, but another look at the data suggests the finding could be statistical noise
