Morning chronotype and exercise associated with reduced ALS risk

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.

Prior COVID infection increases kidney disease risk

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.

Smoking status influences Parkinson's disease risk and mortality outcomes

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.

Study finds brain changes related to worse memory in football players with repetitive head impacts

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.

COVID-19 initially reduced asthma attacks but widened socioeconomic disparities, study finds

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.

Study confirms long-term effectiveness of HPV vaccination

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.

Combining healthy lifestyle and GLP-1 therapy reduces heart risks in diabetes

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.

Road traffic noise linked to immediate heart and blood vessel stress

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.

Long-term cola intake weakens immune cell counts in controlled rat study

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.

Having “hasslers” in your network linked to faster aging and poorer health

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.

Could a rare gene variant help reduce smoking? New study suggests it might

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.

Early-life immune system differences drive childhood eczema risk

A team of researchers at the Icahn School of Medicine at Mount Sinai, Weill Cornell Medicine, and other institutions have uncovered a key biological explanation for why eczema so often starts in childhood.

Chemical signatures in blood could help detect gallbladder cancer

Researchers at Tezpur University in Assam, India, working with scientists at the University of Illinois Urbana-Champaign, have identified distinct chemical signatures in blood that could help detect gallbladder cancer earlier.

No evidence connects tick bites to chronic health problems

When researchers studied Norwegians who thought tick bites caused their chronic health problems, they found no objective evidence linking the symptoms to ticks.

Unexpected behavior observed during interactions between immune cells and dying cells

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is separated from the cytoplasm by a robust nuclear envelope.
