The special scent made only by breeding queens keeps the other naked mole-rats from fighting or reproducing.

Humans think farts are funny — but some animals rely on farts for flotation, communication and more.

People make a lot of gas, and it’s got to come out one end or the other. Understanding those farts and burps could tell us a lot about our health.

A cold blob of water in the North Atlantic suggests that an important ocean current is weakening.

Meats were important, too. But throughout human evolution, fruits may have fueled much of the brain growth in our primate cousins and early ancestors.

The orcas' tactic expands the already broad range of behaviors killer whales use to take down prey.

To show how monkeys think about math and shapes, scientists had them play games — including some designed by kids.

New sensors can map infrasound — a deep-bass thrumming lower than what human ears can hear — emitted by a fire as its flames spread.

Many carbohydrates are important sources of energy, while others offer little benefit. Learn why not all carbs are the same and how our bodies use them.

We’re naturally drawn to sweet foods and drinks. Scientists have designed several ways to make things taste sweet with little or no sugar.

People exposed to low infrasound frequencies had higher levels of a stress hormone in spit and were more likely to rate music as sad.

Soft, sticky marshmallows can be made with just three ingredients. Finding the right ratio of sugar and corn syrup is key to making this sweet treat.

A study of six mummies from ancient Egypt challenges the idea that the weapons buried with some royal women were merely ceremonial.

The tiny cone-shaped structures in arms of chocolate-chip sea stars also triple their skeleton’s strength.

The object orbits a brown dwarf that orbits a star. Astronomers aren’t sure if it’s a planet, a moon — or something else entirely.

These towering walls of water carry a lot of energy. Scientists are investigating what gives rise to such behemoths and their destructive power.

Ancient ground squirrels were anything but picky eaters. Genetic material from grasses to woolly mammoths popped up in frozen squirrel poop.

Ronald Gamble takes cues from the arts to study supermassive black holes and their spacetime geometry.

Cave dirt suggests one ancestral species was using fire around 1.8 million years ago. That pushes back the earliest known use by about 800,000 years.

Climate-friendly food choices, new poop solutions and avoiding animals collected from the wild can all help make pet ownership more sustainable.

Using AI to learn math concepts can boost understanding. But if used to get quick answers, AI can become a crutch that hurts learning.

Worker bees build some ‘cribs’ with a special wax. It seems to turn larva into royals — and challenges the idea that royal jelly was all it took.

The new microraptor, a dino called Jian changmaensis, may have snacked on birds when not gliding through northwestern China some 120 million years ago.

Short for attention deficit/hyperactivity disorder, ADHD affects how people think, learn and process information.

The shape-shifting transformation of the microbe Euplotes gigatrox may reveal how early life learned to act in complex ways.

More and more young people are turning to AI chatbots for mental health help. Know how these tools can actually help — plus the risks of treating chatbots like therapy.

The puffiest planets known in our galaxy orbit a sunlike star more than 1,000 light-years from Earth.

Machines can now print tissues, layer by layer, using "inks" made of living cells. This bioprinting technology brings lab-grown organs closer to reality.

These super high-tech timepieces use the chemical element thorium to keep time. And as the clocks improve, they could help solve some mysteries in physics.

Adult finches make “heat calls” to their eggs when temps rise. Exposure to those songs trigger chicks' developing brains to change in ways that better handle heat.

Low-lying fog clouds host living microbes. That may be good news, because some of them can remove toxic air pollutants, such as formaldehyde.

FDA will now allow the use of bemotrizinol in U.S. sunscreens. This long-lasting chemical protects against the solar radiation that ages and damages skin.

Future forensic scientists, it’s time to fake a crime scene! Get out your corn syrup and red food coloring to learn about blood spatter.

Crystals beneath the skin of nudibranchs, also called sea slugs, allow the creatures to make an array of intense hues with just one material.

The snakes may be tempted onboard by tasty rodents — but train rides can carry cobras far from their forest habitats.

The remains of at least 37 people sit in an ancient stone "jar." They suggest thousands of such vessels in Laos' Plain of Jars are burial vaults.

Professor and pro surfer Cliff Kapono studies how reef structures affect waves, from molecular to macro scales.

Metals like copper tarnish when they react with oxygen in the air. Gold doesn’t, thanks to a quick rearrangement of atoms on its surface.

Past this boundary, nothing that enters a black hole can ever leave — not even light.

Production of the methane is triggered by a newfound feature of the gut microbes — one with a funny name: hydrogenobody.

Attempting to cut a light particle in half would spawn up to infinite new photons, a new model shows.

Balloon-like air sacs in the mice's throats create whistling songs. No other animal is known to make calls in this way.

Some of these predators were as long as whales. Roaming the seas more than 72 million years ago, the octopuses appear to have been the largest invertebrates ever known.

In lab tests, mosquitoes exposed to DEET while feeding learned to associate the chemical with food.

Humidity makes North American sweat bees change color. This trait could be widespread among shiny insects, some biologists now suspect.

New brain scans are helping sort out how our brains process imagined thoughts versus real sensations.

In 2022, NASA smashed a spacecraft into an asteroid. New data show how that impact changed the orbit around the sun of this space rock — and its partner.

This is a trait in which one kind of sensory input, such as sound, can trigger another sense, such as sight.
