Navigated TMS significantly boosts combat PTSD recovery rates

An advanced version of a procedure using magnetic fields to stimulate brain nerve cells in treating depression was significantly effective for 85% of active military and veterans suffering from combat post-traumatic stress disorder enrolled in a recent study, when added to psychotherapy.

Blocking nitric oxide suppresses tumor growth in aggressive pediatric neuroblastoma

The tumor begins before birth. Somewhere in the developing fetus, neural crest cells that should have matured into adrenal tissue or sympathetic ganglia take a wrong turn, and a child is born harboring a malignancy that may not declare itself for months.

Dual perspective AI model achieves high accuracy in early lung cancer diagnosis

Lung cancer remains the leading cause of cancer-related deaths worldwide, accounting for nearly one in five cancer deaths - around 1.8 million lives lost each year.

Smoking shrinks key brain regions while cannabis shows weaker effects

The study highlights brain changes from tobacco use and calls for more research on cannabis, as its effects on brain structure remain inadequately understood.

Challenging processed meat risks for dry-cured ham consumption

The effects of dry-cured ham on cardiometabolic health are nuanced, with evidence suggesting it may not adversely affect key health markers in moderation.

New guidelines aim to improve concussion care for first responders

Management of sports-related concussions has come a long way in the past 25 years: Once considered a minor problem involving minimal time out of the game, a severe knock to the head is now assessed as a potential traumatic brain injury and, if confirmed, requires a structured recovery and an average wait of 13 days before play resumes.

Prickly pear may pack a surprising punch against metabolic syndrome

This narrative review examines how Opuntia ficus-indica fruit, or prickly pear, may help target multiple features of metabolic syndrome through its fiber, betalains, polyphenols, carotenoids, and other bioactive compounds. The authors conclude that the fruit shows promising mechanistic and preclinical potential, but stronger human trials are still needed before firm clinical claims can be made.

How gut microbes may shape heart attack damage and recovery

This review argues that gut microbes and the metabolites they produce, especially SCFAs and TMAO, may shape how the heart responds to myocardial infarction through epigenetic pathways such as DNA methylation, histone modification, and non-coding RNAs. It also outlines potential intervention routes, including diet, probiotics, postbiotics, and metabolite-targeted therapies, while noting that much of the evidence remains translational and not yet clinically definitive.

AI helps researchers find antimicrobial peptides in Earth’s harshest habitats

Researchers built the Extreme Environment Microbiome Catalog from 78,213 genomes across global extreme habitats, revealing major taxonomic and biosynthetic novelty, including 32,715 representative species, nearly 4 billion non-redundant genes, and 163,693 biosynthetic gene clusters. They then used protein language models to identify 3,032 candidate non-toxic antimicrobial peptides, with 84 of 100 synthesized peptides showing antibacterial activity and low cytotoxicity in the 50 tested in mammalian cells.

Metformin mimics exercise-related metabolic effects in prostate cancer patients

A new study has found that metformin, a widely prescribed diabetes drug, may mimic one of exercise's core biological effects in men with prostate cancer, raising levels of a molecule tied to energy balance and weight control even when patients are inactive.
