One day, there could be a new test to screen for type 1 diabetes, now that scientists have found markers in the blood of the umbilical cords of children who were later diagnosed with the disease.

Two emerging pathogens with animal origins - influenza D virus and canine coronavirus - have so far been quietly flying under the radar, but researchers warn conditions are ripe for the viruses to spread more widely among humans.

Taking certain antidepressants at the time of a traumatic brain injury (TBI) is not associated with an increased risk of death, brain surgery or longer hospital stays, according to a study published on January 28, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Researchers at The University of Texas MD Anderson Cancer Center have identified a targetable driver of brain metastases in patients with aggressive inflammatory breast cancer.

In recent years, research into cannabis and its main psychoactive ingredient, Δ⁹-tetrahydrocannabinol (THC), has unearthed medical benefits including anti-inflammatory and neuroprotective properties.

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.
