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

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

The mushroom Psilocybe pelliculosa is one of several species that produce psilocybin, a natural compound with hallucinogenic properties.

Could Psilocybin Help Treat Anorexia? A Small Clinical Trial Suggests the Psychedelic May Make Patients More Open to Recovery

The drug, paired with intensive psychological support, may loosen the rigid patterns of thought associated with the eating disorder, scientists say—but they caution that it is not a magic cure

Spinal Deformities in Saber-Toothed Cat Fossils Reveal How the Now-Extinct Felines May Have Spent Their Final Days

Researchers studied saber-toothed cat vertebrae found in the La Brea Tar Pits in Los Angeles. They identified a surprisingly high number of deformations, including signs of spinal nerve tumors, hinting at a dwindling population suffering the consequences of inbreeding

With Eco Purge, Arya Satheesh won the European category of the 2026 Earth Prize, the largest environmental competition in the world for young students. She was awarded $12,500 to continue to develop her prototype.

This High Schooler Invented a Plant-Based Plastic That Removes Microplastics From the Environment as It Biodegrades

Eighteen-year-old Arya Satheesh created her award-winning Eco Purge to help address the global problem of plastic pollution

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

The experimental therapies are part of a larger movement toward personalized medicine.

After Receiving a Custom Experimental Medicine, a Teen With a Rare Genetic Disorder Walked on His Own for the First Time

The patient’s genetic disorder causes frequent seizures and developmental delays. His progress, along with that of another boy who received a similar personalized treatment, highlights the promise—and challenges—of tailor-made drugs

Of the estimated 899 species of ticks worldwide, about 90 are found in the continental U.S.; however, only four species are responsible for most of the infections found in the U.S. today.

The First At-Home Test for Infected Ticks Could Improve Lyme Disease Diagnosis

LymeAlert will hit the market in August. The latest tool against the tick-borne illness could become a medicine cabinet staple

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

Among medical fields, radiology has pioneered the adoption of A.I. tools. Yet combining the complementary strengths of human and machine intelligence is not straightforward.

How A.I. Will Reshape Radiology—Without Replacing Radiologists

Human experience and flexibility are still necessary even as digital diagnostic tools improve

Keepers and veterinarians are monitoring Milani around the clock.

A Premature Baby Giraffe Born Via C-Section Is Fighting for Her Life at a Zoo in Kansas

According to officials with the Tanganyika Wildlife Park, no known giraffe calf has ever survived the procedure. The youngster, who was recently named Milani, was born on July 11, likely three to seven weeks early

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 Clipper Endeavor was about the same size as a Boeing 737.

This 1950s Airplane Disaster Prompted the Flight Safety Demonstrations Passengers Know Today. Searchers Just Found the Wreckage in the Atlantic Ocean

A team of explorers used an autonomous underwater vehicle to locate the remains of the Pan American ‘Clipper Endeavor’ about five miles off the coast of Puerto Rico

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

A Man With Paralysis Has Regained Feeling and Movement in His Hands After an Experimental Brain Implant

After months of training, the patient can now move his arms and hands and feel the sensation of touch

Two new studies suggest that smartphones are partially to blame for declining birth rates.

Smartphones Might Be Playing a Role in the United States’ Declining Birth Rate, New Research Suggests

Some economists suspect that the technology’s widespread adoption has reduced in-person interactions and increased access to pornography and information on birth control, leading to less unprotected sex

Aging populations are a major driver of the predicted increase in cancer incidents.

Cancer Cases Are Expected to Nearly Double by 2050, Warns the WHO. Low-Income Countries Will Be Disproportionately Affected

In a new report, the World Health Organization predicts that new annual diagnoses will rise from about 20.6 million today to almost 35 million by 2050. The biggest increases will be in Africa and the Eastern Mediterranean region

Public health experts recommend vigorously washing all produce, among other measures.

Cases of a Parasitic Infection That Can Cause Diarrhea for Weeks Are Rapidly Rising in the U.S. Here’s What to Know

The illness is caused by the microscopic parasite Cyclospora cayetanensis, which spreads via food or water contaminated with feces, usually on farms. Health officials are still investigating the source of the multistate outbreak
