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.

Scientists at Gladstone Institutes have flipped the traditional approach to finding potential treatments for deadly diseases.

Young infants hospitalized with respiratory syncytial virus (RSV) often become much sicker compared to those infected with SARS-CoV-2, the virus that causes COVID-19.

A ketogenic diet - one that is high in fat and extremely low in carbohydrates - has been known for decades to reduce seizures in some epilepsy patients.

Being an early bird, also called a morning person, and being more physically active are associated with lower risks of amyotrophic lateral sclerosis (ALS), according to a preliminary study released February 25, 2026, that will be presented at the American Academy of Neurology's 78th Annual Meeting taking place April 18-22, 2026, in Chicago and online.

Scientists may have new answers to why pop-ups or notifications grab our attention. Turns out our attention is on a cycle, shifting seven to ten times per second.

Approximately one in seven adults in the United States has kidney disease, where the organs responsible for filtering waste and excess water from the blood are damaged, according to the Centers for Disease Control and Prevention.

A new study of smokers finds that currently smoking is associated with a lower risk of developing Parkinson's disease, but quitting smoking was associated with a lower risk of death.

In former college and professional football players, a new study has found higher levels of inflammation were associated with worse brain structure, which in turn was related to worse memory.

A large retrospective study of more than 162,000 asthma patients in the Bronx found that asthma exacerbations dropped sharply after the onset of COVID-19 before rebounding in children but remaining lower in adults. Socioeconomic disparities widened during the pandemic, particularly among Medicaid recipients, certain income groups, and patients with documented unmet social needs, while racial and ethnic gaps persisted without significantly expanding.

Human papillomavirus (HPV) vaccination is associated with a significantly reduced risk of invasive cervical cancer, with no indication of waning protection up to 18 years after vaccination, finds a study from Sweden published by The BMJ today.

Individuals living with type 2 diabetes (T2D) had a significantly lower risk of poor cardiovascular health when they used a GLP-1 receptor agonist (GLP-1 RA) in combination with adhering to healthy lifestyle habits, according to a new study led by researchers at Harvard T.H. Chan School of Public Health and the Department of Veterans Affairs Boston Healthcare System.

A new study published in the journal Cardiovascular Research shows that a single night of road traffic noise, at levels that are typical of those living in a city, causes stress to the heart and blood vessels.

Replacing drinking water entirely with sugar-sweetened or sugar-free cola for eight weeks altered gut microbiota composition and immune-related indices in rats, despite no changes in body weight or blood glucose. Both beverages were associated with leukocyte reductions and organ-related biochemical shifts, with sugar-sweetened cola more strongly linked to renal markers and diet cola to elevated liver enzymes.

Researchers analyzed a state-representative US sample to examine whether negative social ties, termed “hasslers,” are associated with epigenetic age acceleration and faster biological aging. Each additional hassler was linked to roughly nine months higher biological age and a 1.5% faster pace of aging, with particularly strong associations for mental health outcomes.

An exome-wide association study of nearly 38,000 smokers from the Mexico City Prospective Study identified rare coding variants in CHRNB3 that are associated with substantially fewer cigarettes smoked per day. Cross-ancestry analyses in European and East Asian datasets support a role for the β3 nicotinic receptor subunit in modulating smoking intensity.

Brains of older adults with super healthy cognition grow more new neurons than those of their peers, according to a study from UIC, Northwestern University and the University of Washington.
