Just a single course of treatment can leave a lasting impression, according to a study of nearly 15,000 people in Sweden

Yaks on the Tibetan Plateau have adapted to deal with high-altitude conditions.

This Genetic Mutation Helps Yaks Survive at High Elevations. It Could Lead to Treatments for Nerve Damage in Humans

Animals that dwell at high altitudes have adapted to cope with low oxygen levels, a condition that damages a vital part of nerve cells

Anopheles mosquitoes are major malaria vectors.

Mosquitoes Have Been Biting Humans for More Than One Million Years

A new study suggests that the deadly insects evolved their taste for human blood much earlier than previously thought, around when Homo erectus migrated into Southeast Asia

Intermittent Fasting Might Not Live Up to the Hype When It Comes to Weight Loss, New Research Suggests

The popular eating strategy is about as effective as doing nothing to lose weight, according to a review of several clinical trials

This 2014 artwork by J.R. superimposes a historic photograph of immigrants on a broken window at the Ellis Island hospital.

A Stay at Ellis Island Hospital Could Determine Whether an Immigrant Had a Chance to Start a New Life in America

Some 276,000 patients were admitted to the medical facility between 1892 and 1951. But the abandoned complex has long been overlooked, and preservationists are fighting to save it

Bird flu devastated a colony of northern gannets, seabirds almost the size of albatrosses, on Bass Rock in Scotland. Researchers working with the birds are holding onto hope that the breeding population will slowly build the colony back.

After a Devastating Bird Flu Outbreak, Scotland’s Seabirds Are Slowly Recovering—and So Are the Scientists Who Witnessed Their Decline

The world’s largest colony of northern gannets was decimated by bird flu in 2022. Now, as their numbers climb again, researchers are collecting data to understand the virus’ lasting effects

Researchers developed a tiny fart-measuring device that snaps into underwear. 

How Often Do You Fart? This ‘Smart Underwear’ Can Keep Track, Because Figuring Out a Baseline Is Important for Science

Researchers have launched a study to find a typical range for flatulence, which has been harder to measure than you might expect

Rhesus macaques at the Oregon National Primate Research Center

A Massive Monkey Research Center Might Turn Into a Primate Sanctuary. Animal Activists Rejoice, While Scientists Worry

The Oregon National Primate Research Center will explore a potentially federally supported transition with the National Institutes of Health

The study involved nearly 132,000 participants whose habits were tracked for roughly 40 years.

Your Daily Coffee Might Be Protecting Your Brain From Dementia, a New Study Suggests

Two to three caffeinated cups a day may help keep the cognitive condition away

This Scientist Brewed and Drank His Own ‘Vaccine Beer’ to Combat a Dangerous Virus. It Seems to Have Worked

Blood tests revealed that the beverage elicited an immune response, according to preliminary research. But far more safety and efficacy testing would be needed before this vaccine could become available

HPV testing is crucial for cervical cancer prevention, but many people miss their exams. 

Testing Menstrual Blood for HPV Might Provide a Less Invasive Way to Screen for Cervical Cancer, a New Study Suggests

While the method shows promise, some experts say that other self-collection devices are more readily available

For their scale, these microbes are faster and more resilient than any human athlete.

If Microbes Entered the Olympics, These One-Celled Superstars Would Win Gold

They race, they spin, they shoot. Meet the organisms for which physical prowess is more than sport—it’s a matter of life and death

Tobacco smoking and alcohol consumption were responsible for 15 percent and 3 percent of all cancer cases diagnosed in 2022, a new study suggests.

Nearly Four in Ten New Cancer Cases Might Be Preventable, According to the World Health Organization

A landmark global study suggests that tobacco smoking, infection and alcohol consumption are the leading causes of preventable cancers

Though still in early stages, some experts say that A.I.-supported screenings could help save patients' health, time and money.

A.I. Could Help Doctors Spot Hard-to-Detect Signs of Breast Cancer During Routine Screenings, a Clinical Trial Suggests

Standard testing can miss some tumors, which are later diagnosed and called interval cancers. They’re often more aggressive than screening-detected disease

Treponema pallidum is a spiral-shaped bacterium that currently exists in three closely related forms, one of which causes syphilis. 

Anthropologists Recover DNA of Syphilis-Causing Bacterium Relative From 5,500-Year-Old Human Remains, the Earliest Ever Found

The findings represent the oldest complete set of genetic information from this bacterial group and shed light on its evolutionary history

Through gene-editing, researchers in the field of synthetic biology hope to make endangered species more resilient against disease or climate change and protect human health, among other goals.

Three Stunning Ways Biologists Aim to Edit Animal and Plant Genes to Fight Diseases and Extinction

The strategy, known as synthetic biology, is gaining momentum globally as a conservation tool and human health solution, despite attracting some critics

Naked mole-rats are unusual for their long lives and resistance to cancer. Now, researchers suggest the rodents not only tolerate but prefer to be in low-oxygen air.

Naked Mole-Rats Prefer Low-Oxygen Air That Would Kill Most Mammals, Adding to Their List of Death-Defying Superpowers

These underground rodents are the first mammals found to actively choose air with lower-than-normal oxygen levels. Their remarkable ability to survive these conditions could offer a key model for researchers studying new treatments for stroke or lung diseases in humans

Researchers investigated the associations between preservatives and the risk of developing cancer and type 2 diabetes.

Eating Large Amounts of Certain Preservatives Might Increase Your Risk of Developing Cancer and Type 2 Diabetes

Two studies tracked more than 100,000 participants over 14 years to reveal the trends. But they can’t confirm a direct link between eating these preservatives and developing disease, especially because some of the additives were eaten in foods that contain known carcinogens
