 SARS-CoV-2, the virus that causes Covid-19, under the microscope

Covid-19 Can Reawaken Dormant Viruses in the Body, Which Might Worsen Symptoms of the Respiratory Illness, Study Suggests

Most people carry a sleeping virus in their bodies, such as the herpesvirus that causes mononucleosis, or the “kissing disease.” A new study hints that Covid-19 triggers their reactivation, which could worsen symptoms and increase the risk of long Covid

Jackie the Bald Eagle, Who Captured Hearts Around the World Via Livestream, Has Died After Battling a Mysterious Illness

A raptor center in California had been caring for the animal since mid-July, after she had an altercation with two young eagles. But she had probably been sick long before then

Older adults are especially at risk of flu-related complications.

For the First Time, an mRNA Flu Shot Will Be Available to Some People in the United States. Here’s What You Should Know

The Food and Drug Administration just approved the new type of flu vaccine for adults ages 50 and older. It relies on the same technology as many Covid-19 jabs. However, it’s unclear whether insurance companies will pay for the novel flu shot

Meteors from the Perseids streaking above Inyo National Forest in Bishop, California, in 2024.

The Perseid Meteor Shower Peaks This Week Amid Ideal Viewing Conditions. Here’s How to Watch the Event’s Bright Shooting Stars

The much-anticipated annual event peaks on the night of August 12 into the next morning. This year, the moon won’t crash the party, as our natural satellite will be in its dark new moon phase

The glassy sphere of hiroshimaite created in the atomic blast that contained a previously unknown metal alloy. 

The Hiroshima Atomic Bombing Birthed a Strange, Never-Before-Seen Material, According to a New Study

The devastating blast vaporized buildings, metal, glass, soil and water. When the substances cooled and condensed, the process created spherical glassy grains—and some of them seem to contain a previously unknown metal alloy

The small blue, shown here, has lost about 40 percent of its habitat in the United Kingdom over the last 150 years.

Butterflies Around the World Are Moving to New Habitats, Largely Because of Climate Change, a Study Suggests

Researchers examined data on 1,758 butterfly species—about ten percent of all those known—from 105 countries and estimated that about one in ten global species has shifted its distribution range

The sticky hairs on the alpine flower trap tiny insects. 

Charles Darwin Theorized That These Plants Were Carnivorous 150 Years Ago. A New Study Proves Him Right

As the naturalist predicted in 1875, some Saxifraga plants consume insects—using sticky hairs to trap them

One source of the cyclosporiasis outbreak is Taylor Farms iceberg lettuce grown in central Mexico.

Two People Died After Getting Sick With Cyclosporiasis, Marking the First Known Deaths Linked to the Ongoing Multistate Outbreak

Both patients, who were in Michigan, had underlying health conditions, according to state officials. The parasite-caused infection usually isn’t life-threatening

Betelgeuse, the inset image in the middle, is located in the constellation Orion, on the right. New images hint at a small companion star, shown in the inset image on the left, orbiting the supergiant star.

New Images Provide the Best Evidence Yet That Supergiant Star Betelgeuse Does, Indeed, Have a Long-Theorized Stellar Companion

The research team is mostly convinced by the data, but they want to capture additional observations in 2027 to confirm what they’ve found

A collection of mammoth bones in a pit in Austria

Ice Age Humans Mostly Killed Female Woolly Mammoths, Suggests Ancient DNA

After analyzing more than 500 mammoth bones, researchers found that ancient humans disproportionately hunted female mammoths for reasons still unknown

Beachgoers rested at Lake Lacanau's Moutchic Beach in southwestern France last week, as clouds of smoke rose into the sky from the Gironde wildfire.

Dangerous ‘Fire Clouds’ Are Making France’s Wildfires Even More Destructive

It’s the first time the phenomenon, which is fairly common in North America, has been observed in France

Traffic can be bad for your health in many ways. Now, researchers have found that it might also increase the risk of Parkinson's disease.

Long-Term Exposure to Road Traffic Noise Might Increase Your Risk of Developing Parkinson’s Disease, New Research Suggests

A study that examined 3.1 million adults in Denmark across 18 years found a modest but consistent correlation. The findings hint that disruptive environmental sounds are a credible risk factor for the brain disorder

Heading to a National Park? Watch Out for Elk. They Attack People Way More Often Than Bears Do, According to a New Study

While many people worry about grizzlies, an analysis of almost 3,000 encounters with aggressive wildlife in Canadian national parks and historical sites found that the huge ungulates were responsible for more than half of them

The new work contributes to a broader shift in bilingualism research, which is moving toward the view that grammar is supported by a shared, flexible brain mechanism that operates across all languages.

How Does a Bilingual Speaker’s Brain Process Two Languages? New Research Suggests That Both Rely on the Same Neural Wiring

Scientists have long wondered whether different neural mechanisms govern each language within a bilingual speaker’s brain. A recent study of people who speak both English and Spanish hints at a single “grammatical engine”

Is This Giant Celestial Body a Moon, a Planet or Something in Between? The Strange Object Calls Astronomical Labels Into Question

The newly found object, estimated to be roughly as massive as Jupiter, orbits a brown dwarf—a “failed star”—which in turn circles a small star. For now, researchers are calling the puzzling body an “exosatellite”

The drug targets the tau protein, which accumulates and forms tangles (seen in blue) in nerve cells.

Experimental Alzheimer’s Drug That Fights a Tough-to-Target Protein Shows Promise at Slowing Cognitive Decline in a Clinical Trial

Recently FDA-approved treatments work to clear clumps of the protein amyloid beta in the brain. A drug that instead goes after tangles of the protein tau can yield similar cognitive outcomes, a new study suggests

The brown trout were likely introduced to guarantee a food source if reindeer hunts were unsuccessful, according to a new study.

Hunter-Gatherers Brought Trout to a Norwegian Mountain Lake 7,000 Years Ago, the Earliest Known Example of Humans Translocating Fish

Researchers have long known that the animals were introduced into the region’s high-altitude bodies of water, but they weren’t sure when it happened or whether humans had a hand. Analyses of recently discovered ancient fish traps provide new clues

A pregnant naked mole-rat queen, on the left, and a worker, on the right, sniff each other.

Naked Mole-Rat Queens Emit a Special Scent to Stop Their Rivals From Reproducing, a New Study Suggests

The strange-looking creatures are one of two known mammals that use a social structure like that of bees and ants. A ruling rodent maintains power over her colony via one key chemical compound, according to new research

Keith Thomas is now able to grasp, lift and drink from a cup on his own.
