Lung cancer cells, shown in green, growing in a mouse heart

Cancer Is Somehow Rare in the Heart. Turns Out, the Organ’s Rhythmic Beat Might Keep the Disease at Bay, a Mouse Study Finds

Less than 1 percent of cancers start in the heart, and disease that begins elsewhere seldom spreads to the blood-pumping organ. New research suggests mechanical force might have a protective role

An illustration of lymphocytes, or white blood cells in the immune system, which include T cells and other disease-fighting cells

You’ve Been Told to ‘Feed a Cold.’ Turns Out, Eating May Truly Boost Your Immune System Cells, According to a New Study

T cells, which target infection and disease, can become more effective after a meal. The finding might help improve cancer-fighting therapies and optimize our response to vaccines

Pluto was considered the solar system's ninth planet for more than 70 years.

Could Pluto Once Again Be Considered a Planet? New Remarks From NASA’s Administrator Highlight an Enduring Debate Among Scientists

Two decades ago, the International Astronomical Union—which defines and names celestial bodies—redefined the criteria for being a planet, putting Pluto into the new category of dwarf planet

The Eta Aquarids as seen from Sri Lanka in 2024

The Eta Aquarid Meteor Shower Peaks This Week, but a Bright Moon Might Spoil the Show

This annual event, which peaks on the night of May 5 into the next morning, comes from the trail of debris left by Halley’s comet. It’s best viewed from the Southern Hemisphere, but skywatchers in the north can catch a glimpse

Tatooine is a fictional desert planet with two suns. No such planet had been found when this scene in Star Wars: Episode IV–A New Hope ​​​​​​was created.

Astronomers Discover 27 Potential Planets Each Orbiting Two Stars, Just Like the Fictional Tatooine in ‘Star Wars’

The findings could more than double our current database of worlds that loop around binary star systems. But researchers need to analyze more data before they can officially celebrate a new trove of far, far away exoplanets

Cattle are a major driver of methane emissions.

Why Do Cows Burp Up So Much Planet-Warming Methane? A Newly Discovered Structure in Their Gut Microbes Could Be a Culprit

The “hydrogenobody” is an organelle inside certain microorganisms that live in a special stomach chamber in cattle, sheep and goats, according to a new study

The A.I. model outperformed two doctors when presented with data from dozens of real E.R. patients.

A.I. Outperformed Doctors at Diagnosing Real-World E.R. Patients in a New Study. That Doesn’t Mean Computers Will Replace Clinicians

One of OpenAI’s large language models did better than physicians in several experiments, hinting that A.I.-assisted emergency medical care could be around the corner

Left: Experimental setup of some chickpeas growing in artificial lunar dirt. Right: A chickpea root covered in the simulated moon soil, which is sharp and glass-like. 

Hummus Made From Moon-Grown Chickpeas Might Be on the Menu for Future Lunar Residents

Researchers successfully grew and harvested chickpeas in simulated moon dirt—with a little help from worm poop and a beneficial fungus. However, they’re still testing whether the legumes are safe to eat

Lava, seen as darker brown rocks, from Methana's most recent eruption flows through ancient limestone into the sea.

This Greek Volcano Seemed Quiet for 100,000 Years. Then It Erupted Again. Should Scientists Take a Second Look at ‘Extinct’ Volcanoes?

By reconstructing a 700,000-year history of Methana volcano, geologists found a prehistoric phase when it appeared inactive on the surface, despite magma building up below ground

Dead Bodies Filled a Mass Grave When the First Plague Pandemic Struck This Early Medieval City. New Research Explores the Identity of the Victims

Researchers analyzed isotopes and DNA in the teeth of remains found in a mass grave from the Plague of Justinian, which swept through the Byzantine Empire

The largest 3D map of the universe. Earth is at the center, and each point marks a galaxy.

This Is the Largest, Most Detailed 3D Map of the Universe. It’ll Help Astronomers Investigate a Cosmic Mystery: Dark Energy

The Dark Energy Spectroscopic Instrument spent five years observing the sky from Arizona. Now, researchers have a trove of data to study how the universe has evolved over billions of years

Study author Gregory Bonito collects truffles in Australia. 

Australia Has a Surprisingly Successful Truffle Industry. This New Study Could Explain Why

Researchers examined hundreds of soil samples to uncover why the expensive fungi are thriving in the country

Two Athletes Smashed a Marathon Milestone, Running 26.2 Miles in Under Two Hours. Here’s the Science Behind Their Achievements

An intense training regimen, good weather conditions, physiology and lightweight shoes probably played a role in their astounding performances during the London Marathon on Sunday

Microscope image of a cross-section of a mouse nose. The animal was genetically altered so that its nerve cells used for smell glow green. Some dying nerve cells appear red.

Scientists Create the First Detailed ‘Smell Map’ of Odor Sensors in the Mouse Nose—and Sniff Out Some Surprising Discoveries

In two new studies, researchers used genetic techniques to upend a longstanding assumption that nerve cells with scent detectors were randomly arranged. They don’t know whether the same spatial organization is found in human noses

Newborns usually go through tests to determine whether they have hearing problems. Undiagnosed issues can delay developmental milestones.

The FDA Approves the First-Ever Gene Therapy for Deafness, Which Aims to Restore Hearing in Kids With a Rare Inherited Condition

The agency’s decision is based on results from a clinical trial in which the treatment improved hearing in 80 percent of the pediatric participants. However, Deaf community advocates worry about the push to cure hearing loss

The first image of newly hatched California giant salamanders in the wild can teach biologists about the nesting habitat of the little-known species.

A Snorkeling Biologist Snapped the First-Ever Photo of Newly Hatched California Giant Salamanders in the Wild. Here’s Why That’s a Big Deal

The discovery provides another key data point about a little-known species for which every observation matters

An intrepid male orangutan crosses an artificial bridge connecting trees on either side of a public road.

Watch the First Known Video of a Sumatran Orangutan Crossing a Human-Made Wildlife Bridge in the Treetops

A public road in Indonesia separates forests housing about 350 wild orangutans, among other animals. So, conservationists built several canopy bridges to prevent habitat fragmentation

Sea ice forms off the edge of the Brunt Ice Shelf in Antarctica’s Weddell Sea.

Warm Waters Are Usually Trapped Deep Within the Southern Ocean. Now, They’re Encroaching on Antarctica, Threatening Its Ice

Two new studies that relied on data from a fleet of diving robots show how climate change is altering ocean movements in ways that jeopardize the stability of the polar ice cap

Undetectable infrasound might explain why some people report paranormal experiences, a new study suggests.

Worried Your House Is Haunted? The Spooky Sensation Might Arise From a Surprisingly Simple Source

Infrasound—noise below the range of typical human hearing—from power, heating and mechanical systems within buildings can make people feel irritated and induce a stress response, according to a new study

After researchers aboard the Okeanos Explorer ship couldn't figure out the orb's identity, they sent it to the Smithsonian's National Museum of Natural History for a more thorough investigation.
