This study mapped how EPA and DHA are distributed across lipid classes in microalgae, fish, krill, and commercial omega-3 supplements using lipid-class–resolved analysis. It shows that lipid structure, not just total omega-3 content, differs markedly across sources and may influence their nutritional relevance.

This cross-sectional analysis of 8,320 Brazilian adults quantified melatonin intake from habitual diets and examined associations with multiple chronic health outcomes. Higher dietary melatonin intake was inversely associated with obesity and depression in a non-linear pattern, with no significant associations observed for other conditions.

Using single-cell epigenomic profiling of immune cells from 110 individuals, researchers show that genetic variation and environmental exposures shape the human immune system through distinct DNA methylation mechanisms. Genetic effects concentrate within gene bodies of memory cells, while environmental exposures primarily remodel regulatory regions in naive immune cells.

This cross-sectional study of 300 school-aged girls in Tehran found that higher air pollution exposure was consistently associated with poorer concentration, while dietary antioxidant capacity showed weaker, model-dependent links to attention. No significant associations or interactions were observed for short-term memory, highlighting pollution exposure as the dominant factor influencing attentional performance.

Researchers modelled future injury risk in male professional footballers across seven European leagues and linked this risk to market valuation using a two-stage econometric approach. A higher predicted probability of severe or recurrent injury was associated with a substantial reduction in players’ market value.

Lifetime alcohol intake, not just recent drinking, is associated with colorectal cancer risk in older adults followed in the PLCO Cancer Screening Trial. Heavy and consistent long-term drinking was linked to higher colorectal cancer risk, while alcohol cessation was associated with lower odds of early, nonadvanced adenomas.

UVA Health scientists are reporting promising success as they pioneer a new way to create vaccines far more quickly, nimbly and inexpensively than ever before.

The tiny zebrafish is helping researchers rapidly determine whether a newborn's genetic mutation is likely to cause spinal muscular atrophy (SMA), one of the leading causes of infant mortality worldwide.

More than 135 million American adults are either living with or at risk for type 2 diabetes (T2D), elevating the need for more evidence-based dietary guidance to help this growing population achieve optimal health and reduce risks for T2D and its complications.

A four-biomarker blood panel of aminopeptidase N (ANPEP), polymeric immunoglobulin receptor (PIGR), CA19-9, and thrombospondin-2 (THBS2) enhanced the detection of pancreatic ductal adenocarcinoma (PDAC) compared to measuring CA19-9 levels alone.

A Japanese research team has discovered a new compound that can advance the body's internal clock—offering hope for faster recovery from jet lag and better adaptation to night-shift work.

Each year, 20,000 children and adolescents across the U.S. lose a parent to gun violence, while an estimated 2-3 times more have a parent who has been injured due to a firearm.

Men begin developing coronary heart disease - which can lead to heart attacks - years earlier than women, with differences emerging as early as the mid-30s, according to a large, long-term study led by Northwestern Medicine.

New study suggests that an experimental peptide developed at the Hebrew University may reduce recurring seizures and support brain function by targeting underlying oxidative stress and inflammation processes linked to epilepsy.

New research in Brain & Behavior found a link between screen time and adolescents' sleep quality and beliefs about healthy lifestyles.

Historical data indicate that men develop coronary heart disease (CHD) 10 years before women. A recent study in the Journal of the American Heart Association indicates that this sex gap still remains.

Patients were 28 percent more likely to get a flu shot when they got a text message reminder and their primary care provider already had an order for the shot waiting, new research from the Perelman School of Medicine showed.

Researchers have identified a protein pattern that, already at birth, looks markedly different in those who later go on to develop type 1 diabetes. The findings show that a combination of several factors during pregnancy increases the risk of the child later developing the disease. The study is published in Nature Communications and was led by researchers at Linköping University, Sweden, and the University of Florida, USA.

Virginia Tech researchers discovered an indication hidden in the brain that may help doctors identify children suffering from a rare genetic disease earlier. Their findings were published recently in EMBO Molecular Medicine.

Because treatment of the whole prostate can lead to long-term side effects in patients with prostate cancer, interest in minimally invasive, focal treatment options has been growing for certain patients.
