Brain scans find no evidence of widespread inflammation in long COVID

A new brain imaging study has found no evidence of widespread brain inflammation in patients suffering from prolonged symptoms after COVID-19 infection. Instead, the most severe long COVID symptoms were associated with increased brain activity in regions involved in mood and emotion.

NIH researchers discover how weight-loss drugs alter brain cells

A team of researchers at the National Institutes of Health (NIH) have unveiled new details about the events GLP-1 receptor agonists trigger within neurons, which have been largely unexplored until now.

Boston Children's scientists create new booster-free mRNA vaccine strategy

In a new study published in Nature Immunology, researchers at Boston Children's Hospital demonstrated that pairing the original COVID-19 mRNA vaccine with an immune system enhancer, known as an adjuvant, extended the duration of the vaccine's protection in mice from a few months up to two years.

Cincinnati scientists grow larger gut organoids with self-developing nerve cells

Thanks to special 3D-printed scaffolding trays designed by experts at Cincinnati Children's, researchers can now produce larger versions of functional human gut organoids twice as fast as previous methods-and these organoids grow their own nerve cells.

Optimized extended PCLS culture system extends tissue viability up to two weeks

Precision-cut liver slice (PCLS) technology has long been regarded as a promising ex vivo platform because it preserves the native multicellular architecture of liver tissue.

What medicine-exposed rats reveal about the next urban zoonotic threat

Researchers found that more than half of urban rats sampled from low-income communities in Salvador, Brazil, carried active pharmaceutical ingredients in their brain tissue. These pollutants were associated with altered zoonotic infection patterns, including lower Leptospira infection probability in rats carrying azithromycin and higher Capillaria infection probability in rats carrying citalopram.

Explainable AI could make breast cancer drug predictions safer and clearer

AI-driven genomic analysis could help researchers identify existing drugs that may be repurposed for subtype-specific breast cancer treatment. The review proposes an interpretability-driven framework that links multi-omics data, mechanistic validation, and clinical translation to make AI predictions more transparent and clinically useful.

Disrupted sleep rhythms may increase dementia risk through impaired waste clearance

Why are conditions such as chronic stress, depression, cardiovascular disease, fragmented sleep, and aging all associated with a higher risk of dementia? In a new review piece in Science, University of Rochester Medicine neuroscientist Maiken Nedergaard, MD, DMSc, proposes that many of these seemingly different conditions may converge on the same biological problem: disruption of a sleep-dependent brain rhythm that helps clear waste from the brain.

ISTA researchers prove keratin is indispensable for coherent cell migration

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they need to move together as a coherent tissue while modulating the driving forces behind their movement during early development. But what happens when keratin is missing?
