How microalgae, fish, and krill store omega-3s differently and why it matters
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.

Eating melatonin-rich foods is linked to lower obesity and depression rates
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.

How DNA and life experiences leave distinct marks on the human immune system
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.

Air pollution, not diet, shows the strongest link to poorer concentration in schoolgirls
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.

Why predicted injury risk is quietly dragging down football transfer values
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 heavy drinking sharply raises colorectal cancer risk, major US study finds
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.

Zebrafish can play a decisive role in clinical interpretation of spinal muscular atrophy
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.
