Drug combination shows greater weight loss while preserving muscle mass

A recent research study found that a combination of the GLP-1 receptor agonist semaglutide and bimagrumab, an antibody that blocks activin signaling pathways, results in greater weight loss while also preserving lean mass, such as skeletal muscle and connective tissue.

Study finds toddlers who eat more ultra-processed foods show slightly higher behavioral symptoms

A prospective analysis of 2,077 children in the Canadian CHILD Cohort Study found that higher intake of ultra-processed foods at age three was associated with slightly higher behavioral and emotional symptom scores by age five. Modeling showed that replacing 10% of calories from ultra-processed foods with minimally processed foods was associated with modestly lower symptom scores.

Teenage aggression linked to faster biological aging and health risks later in life

Teens who frequently lash out at others may face lasting physical health consequences later in life, according to research published by the American Psychological Association.

Are socially isolated people more likely to develop cancer? Study of 350,000 adults explores the risk

A large UK Biobank study of more than 350,000 adults found that social isolation, but not loneliness alone, was associated with a modest increase in overall cancer risk during over 11 years of follow-up. The association was stronger in women and appeared partly linked to socioeconomic disadvantage, unhealthy behaviors, and inflammatory processes.

Puberty reshapes DNA to worsen or reverse insulin resistance

This study uncovers epigenetic changes during puberty that correlate with insulin resistance, offering insights into childhood obesity and metabolic risk.

Global breast cancer burden rising fastest in low-income countries

Despite recent advancements in breast cancer treatments, new breast cancer cases in women are predicted to rise by a third globally from 2.3 million in 2023 to more than 3.5 million in 2050.

The surprising neurological benefits of GLP-1s

For people with chronic migraine, taking glucagon-like peptide-1 receptor agonists, or GLP-1 drugs, for other conditions such as diabetes and weight loss, was associated with fewer emergency department visits and hospitalizations overall, and with less need for medications used to stop and prevent migraine attacks, according to a preliminary study released March 1, 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.

Living near nuclear power plants is associated with higher cancer mortality, national US study reports

A nationwide ecological study of US counties from 2000 to 2018 found that greater proximity to operational nuclear power plants was associated with higher cancer mortality rates, particularly among adults aged 65–74 years. The analysis used inverse-distance weighting within 200 km and adjusted for demographic, socioeconomic, environmental, and healthcare factors, but did not measure individual radiation exposure.

Higher tyrosine levels linked to shorter lifespan in major UK Biobank analysis

Researchers analyzed over 272,000 UK Biobank participants and used Mendelian randomization to investigate whether circulating phenylalanine and tyrosine influence lifespan. Genetically predicted higher tyrosine levels were linked to shorter lifespan, particularly in men, while phenylalanine showed no independent effect after adjustment.

Can peanut butter improve mobility after 65?

Research indicates that peanut butter can enhance muscle power in older adults, but its impact on overall physical function and gait speed is limited.

How physical strength and self-belief grow together in teens

Physical fitness and psychological resilience develop side by side during adolescence, a life stage that lays the foundation for adult health. Cardiorespiratory endurance, muscular strength, and agility are well-known predictors of cardiometabolic health, while self-efficacy, defined as the belief in one's ability to overcome challenges, shapes motivation, persistence, and coping strategies.

Heavy alcohol intake is associated with dangerous belly fat accumulation, large UK study shows

In a large UK population cohort, higher weekly alcohol consumption was dose-dependently associated with greater visceral fat mass measured by DXA, independent of total body fat. Heavy drinkers showed over 10% higher proportional visceral fat compared with lower consumption groups, a pattern linked to increased cardiometabolic risk.

Organ donation after circulatory death expands transplant opportunities

Organ donation after the heart stops beating, a practice called donation after circulatory death, has gone from rare to routine in the United States, a new study shows.

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.

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.

Social media muscle content raises steroid use intentions in young men

A study links muscle-focused social media content to increased intentions to use anabolic steroids among young men, highlighting risks of body comparison.

Combined GLP-1 and GLP-2 treatment appears safe but does not beat placebo for obesity

In a 12-week randomized phase IIa trial in adults with obesity, the dual GLP-1/GLP-2 receptor agonist dapiglutide was well tolerated but did not achieve statistically significant weight loss compared with placebo at 4 mg or 6 mg doses. Although the higher dose showed modest within-group weight reduction and improved HbA1c, unexpectedly substantial placebo-associated weight loss limited the observed treatment effect.
