The variants are present in fewer than 1 percent of people, but they were 2.7 times more likely to appear in lefties than in righties

Peter Higgs stands in front of a photograph of the Large Hadron Collider at the Science Museum in London in 2013. The year before, researchers smashing protons together at the collidor had discovered evidence of a fundamental particle, which Higgs had proposed nearly 50 years prior.

The Nobel Prize winner predicted the Higgs boson, a fundamental particle that scientists successfully discovered in 2012, explaining how particles get their mass and underlying a key theory of the universe

Observations of volcanic vortex rings have been reported at a number of volcanoes over the past several hundred years. The most recent rings emerging from Etna were first spotted last Wednesday.

A slice of the largest 3D map of the universe ever made, depicting 600,000 galaxies across the cosmos—less than 0.1 percent of the map's total. Earth is at the tip in the lower center, and the most distant galaxies represented are 11 billion light-years away.

Dark Energy Could Be Evolving Over Time, Raising Questions About the Nature of the Cosmos

The largest 3D map of the universe ever made hints that dark energy might not be a constant, though the findings must be backed up with more data

A picture of the International Space Station captured by the Space Shuttle Discovery in 2007. Last month, a two-ton pallet of batteries released by the space station in 2021 re-entered Earth's atmosphere. It was expected to mostly burn up upon re-entry, but a two-pound piece of debris that struck a Florida home may have come from the batteries.

Falling Object That Crashed Into Florida Home May Be Debris From the International Space Station

Nobody was hurt by the mysterious, two-pound object, but experts speculate it may be a piece of batteries ejected from the station in 2021

Methane plumes observed at a Louisiana landfill during the study. More than 14 percent of U.S. methane emissions were reported to have come from landfills in 2021.

More Than Half of U.S. Landfills May Be Methane 'Super-Emitters,' Study Finds

Aerial observations of hundreds of large landfills across 18 states found they are leaking 40 percent more methane than is reported to the EPA

A composite image showing multiple stages of 2019's solar eclipse as seen from Chile.

This Handheld Device Allows Blind People to Experience the Solar Eclipse With Their Ears

The technology, which translates the intensity of sunlight into a range of sounds, was designed to make eclipses more accessible to visually impaired people

One difference between resident and transient killer whales is their fins. Residents have more rounded, curved dorsal fins, while those of transients are straighter and more pointed.

Two New Species of Killer Whale Should Be Recognized, Study Says

A couple of eastern North Pacific populations of orcas have qualities that set them apart, according to researchers

Melting ice redistributes mass to Earth's equator, slowing its spin rate. Changes in Earth's spin affect its synchronization with atomic clocks.

Melting Polar Ice Sheets Are Slowing Earth's Rotation. That Could Change How We Keep Time

As ice melts into water and flows toward the equator, it redistributes mass around the Earth, affecting the planet's spin, a new study finds

Study participants who reported eating during shorter time frames were more likely to die from heart disease during the period of the study.

Intermittent Fasting Linked to Higher Risk of Death From Heart Disease, Preliminary Study Finds

New research challenges the idea that restricting eating to a limited time frame is beneficial—though the work has some notable limitations, such as a reliance on self-reported eating habits

The new image of the Milky Way's black hole, seen in polarized light. It shows the organized magnetic fields that surround the black hole itself, from which no light can escape.

Astronomers Capture Dazzling New Image of the Black Hole at the Milky Way's Center

The first image of the black hole taken in polarized light, the new view shows the supermassive structure's magnetic fields and hints that it could be hiding an enormous jet

Japanese tits have previously been observed combining different calls into phrases to convey meanings. The birds may also use their wings to signal to their partner that they should enter the nest first.

These Small Birds Flutter Their Wings to Say 'After You' to Their Partner

A new study of Japanese tits provides the first evidence of non-primate animals using gestures to convey messages

Indonesia's Lake Toba, formed by a volcanic eruption around 74,000 years ago. In the new study, researchers uncovered fragments of glass from the eruption at an archaeological site in northwest Ethiopia, pointing to the volcano's global impacts.

Stone Age People Survived a Supervolcano Eruption by Adapting to Dry Periods, Archaeologists Suggest

Humans living in northwest Ethiopia around 74,000 years ago switched to eating more fish following the eruption, a behavior that might have enabled migration out of Africa

Surgeons perform the pig kidney transplant. The surgery took place last week, and the patient is recovering well and is expected to be discharged from the hospital soon.

Doctors Take Another Step Toward Animal-to-Human Organ Transplants With the First Pig Kidney Transplant

The experimental procedure was done on a man experiencing end-stage kidney failure last week who had been on the transplant waiting list for two years

Archaeologists uncovered a trove of artifacts, including this scorched axe, from a Bronze Age settlement called Must Farm.

Incredibly Well-Preserved Bronze Age Village Reveals a Snapshot of Early British Life Before a Fire

Residents fled when flames burned through the Must Farm settlement, and now, archaeologists have unearthed its buildings and objects that were preserved in a riverbed

Humans produce about 400 million metric tons of plastic waste each year. Some chemicals in plastics have been linked to health problems for humans and animals.

A new database catalogs 16,000 chemicals found in plastics and identifies more than 4,200 that are potentially hazardous to human health and the environment

Aboard the International Space Station, astronauts experience near-weightlessness—and fluid accumulates in their heads as a result, which could potentially be one cause of headaches.
