Most air cleaning devices have not been tested on people and little is known about their potential harms

A research team led by Bristol and Cambridge universities has demonstrated that the polymer material used to make a new artificial heart valve is safe following a six-month test in sheep.

From "try yoga" to "start journaling," most mental health advice piles on extra tasks. Rarely does it tell you to stop doing something harmful.

It's a fact of life: Some people age better than others. Some ease into their 90s with mind and body intact, while others battle diabetes, Alzheimer's or mobility issues decades earlier. Some can withstand a bad fall or bout of the flu with ease, while others never leave the hospital again.

A new Zika virus vaccine developed in Brazil by researchers at the Institute of Tropical Medicine of the University of São Paulo's Medical School (IMT-FM-USP) has been shown to be safe and effective in tests with mice.

By revealing the molecular mechanisms behind the peacekeeping abilities of specialized immune cells, scientists are uncovering new pathways for treating autoimmune conditions and detecting diseases like cancer.

Multiple sclerosis (MS) has long been regarded as a disease with different subtypes such as "relapsing" or "progressive." An international study, published on August 20, 2025, in Nature Medicine under the leadership of the Medical Center—University of Freiburg and the University of Oxford, challenges this dogmatic model after analyzing the NO.MS cohort (study data from Novartis).

Memories of significant learning experiences—like the first time a driver gets a speeding ticket—are sharp, compared to the recollection of everyday events—like what someone ate for dinner two weeks ago. That's because the human brain is primed to learn from helpful associations.

Young people who are offered confidential and free access to prescription contraception methods are significantly more likely to use them, according to a new McMaster University study.

There is often a dramatic scene in crime shows where an eyewitness points to a suspect in a police lineup. This identification looks convincing on television, and it is also convincing in real-world investigations. But here's the problem: eyewitnesses can often be wrong. Their mistakes are a leading cause of wrongful convictions.

An international research team from Leibniz-FMP, the University of Oxford, and the University of Birmingham have developed a novel imaging approach to track how popular dual agonist drugs like tirzepatide interact with cells in the pancreas and brain. Published this week in Nature Metabolism, the findings could support the design of more effective treatments for diabetes and obesity.

New research from Dana-Farber Cancer Institute shows that a new class of drug results in cell death in cancers, such as small cell lung cancer, with a disabled quality control cell cycle checkpoint known as the G1/S checkpoint. The evidence gathered in the Oser Lab at Dana-Farber supports testing of the strategy in humans.

Cancer cells can break down the protective covers around nerves, causing nerve injury that triggers chronic inflammation, leading to immune exhaustion and eventual resistance to immunotherapy, according to new research from the University of Texas MD Anderson Cancer Center.

The legacy of redlining—the 20th-century mapping practice that denied loans and other services to minorities based on their neighborhoods—continues to resonate in cities. New research from Virginia Commonwealth University and Virginia State University finds a spatial overlap between formerly redlined neighborhoods and violent injuries among youth in the city of Richmond today.

The U.S. Food and Drug Administration has approved Tonmya (cyclobenzaprine hydrochloride) sublingual tablets for the treatment of fibromyalgia in adults.

Sweat does more than just cool down an overheating body. Measuring the chemical makeup of an individual's sweat—specifically the levels of chloride, a chemical component of salt—can serve as an early warning system to help inform the diagnosis of cystic fibrosis, a genetic disease that damages the lungs and digestive system.

A new study has created the first single-cell map of how DNA is regulated and organized inside different cell-types of human fat tissue. The research shows that many genetic risk factors for abdominal obesity reside in epigenomic regions of fat cells, offering clues about how body fat is genetically and epigenetically regulated and how it might be better controlled. The study, by co-first authors Zeyuan (Johnson) Chen and Sankha Subhra Das, is published in Nature Genetics.

The U.S. Food and Drug Administration (FDA) has approved Novo Nordisk's popular weight-loss drug Wegovy to treat a serious form of fatty liver disease.

A new Northwestern Medicine study has revealed how a common inherited mutation disrupts red blood cell development and sparks inflammation that can lead to leukemia, according to findings published in Nature Communications.
