Spending time in nature, even briefly, triggers changes in the brain that calm stress, restore attention and quiet mental clutter, a new study has found.

For many women with breast cancer, the very treatment that saves their lives can also bring fatigue, loss of muscle mass, emotional strain and other daunting obstacles.

Cancer treatment can take a profound financial toll, and new research shows the damage does not stop at the bank account.

An international team of scientists has shed light on the development of the malaria parasite and have identified a unique protein essential for its survival and transmission, which offers a promising new target for antimalaria drugs.

A global team of scientists has identified an often-overlooked biological system - biofilms - as a critical factor in the future of human space exploration.

High-grade astrocytoma, which includes glioblastoma, is a fast-growing, aggressive brain cancer that often returns after the tumor is removed, making it difficult to treat. Patients

A new study found that heart attack deaths were up among younger adults with women more likely than men to die after a first heart attack.

A new study spanning eleven years of data has revealed a clear link between wildfire smoke pollution and an increase in violent assaults in Seattle.

Synovial sarcoma is an aggressive malignant tumor that primarily affects the limbs of teenagers and young adults.

Per- and polyfluoroalkyl substances (PFAS) – 'forever chemicals' in common parlance – are a class of thousands of synthetic chemicals often used in non-stick coatings, water-resistant fabrics, fire-fighting foams, food packages, cleaning products, and plastics.

Over two decades, medical care improvements increased health spans in the U.S. by 1.3 years and medical spending by $234,000 per person over their lifetime – or about $182,000 per additional healthy year of life gained – when measured from birth. These are among the key findings in a new in-depth national study published today in Value in Health.

Even in the womb, where all oxygen is provided by the parental placenta, fetuses can-and do-yawn. More yawns during observation were associated with a lower weight at birth-potentially indicating mild fetal stress in the womb, according to a study published February 25, 2026 in the open-access journal PLOS One by Damiano Menin, of the Università degli Studi di Ferrara in Italy, and colleagues.

Researchers have investigated the role of a certain enzyme in regulating energy in muscle and exercise performance for decades, but a new study by Virginia Tech scientists has identified more precisely than ever how this mechanism works.

When removing cancerous tissue in the brain, neurosurgeons often use "awake brain mapping" to minimize the risk of causing unintended disruptions to a patient's quality of life while removing as much tumor as possible. This practice, which has been used for decades, involves waking a patient up mid-surgery to test their neurocognitive functions in real time by stimulating the brain surface and assessing for functional changes.

A new, daily oral tablet that combines two current HIV treatment medications, bictegravir and lenacapavir (BIC/LEN), may be able to effectively replace more complicated HIV treatment regimens used by people living with HIV who are long-term survivors, according to the results of a new phase 3 clinical trial published in The Lancet.

Telemedicine visits are five times less costly than in-person appointments for the most common conditions able to be treated by both forms of visits, new research from the Perelman School of Medicine at the University of Pennsylvania shows.

Daily aspirin use does not offer a quick or reliable way to prevent bowel cancer in the general population and carries immediate risks of serious bleeding, a new Cochrane review finds.

Researchers from the University of Sydney and the Centenary Institute have discovered how a promising class of experimental antibiotics disrupts the bacterium that causes tuberculosis (TB), paving the way for urgently needed new treatments.

​Benzodiazepine treatment declined among U.S. adults between 2018 and 2022, with the steepest drop among adults ages 56 and older, according to a new study by researchers at the Columbia University Mailman School of Public Health and Columbia University Irving Medical Center.

MIT researchers have discovered that two common genetic mutations that cause Rett syndrome each set off a molecular chain of events that compromises the structural integrity of developing brain blood vessels, making them leaky.
