Longer continuous walks linked to sharply lower heart risk, study finds

Walking in bouts of 10–15 minutes or longer was associated with substantially lower cardiovascular risk among adults taking fewer than 8,000 steps a day, with 15‑minute‑plus bouts tied to about a two‑thirds lower risk than very short walks, according to research published in Annals of Internal Medicine.
Drug combo cuts prostate cancer death risk by over 40 percent
A combination of enzalutamide and hormone therapy has reduced the risk of death by more than 40% in men with recurring prostate cancer, according to a major clinical trial. The study, involving over 1,000 patients worldwide, was led by researchers at Cedars-Sinai and presented at a medical congress in Berlin. Experts describe the findings as a game changer for treating aggressive cases.
Neurons use fat—not just sugar—for energy, study ties pathway to rare brain disorder
Heather Vogel Fact checked
Researchers in Australia and Finland report that neurons can fuel themselves with fat as well as sugar, challenging long‑held assumptions about brain energy. The discovery, published in Nature Metabolism, links a lipid‑processing enzyme to a rare hereditary spastic paraplegia and suggests that targeted fatty acid supplements may restore cellular energy in laboratory models.
Serum promotes hair growth by mimicking skin irritation effects
Researchers have developed a serum that stimulates hair growth in mice by replicating the fatty acid release triggered by skin irritation, without causing discomfort. The treatment, based on monounsaturated fatty acids, shows promise in lab tests on human hair follicles. Scientists plan human trials following encouraging results.
Hidden fat damages arteries even in seemingly healthy people
Researchers at McMaster University have discovered that visceral fat around organs and fat in the liver can silently harm arteries, increasing stroke and heart attack risks, regardless of outward appearance. The study, involving MRI scans of over 33,000 adults, challenges the reliability of BMI for assessing cardiovascular health. Published on October 17, 2025, the findings urge a shift toward imaging-based evaluations.

Researchers directly visualize alpha‑synuclein oligomers in human Parkinson’s brain tissue
Heather Vogel Image generated by AI Fact checked
Scientists in the U.K. and Canada report the first direct visualization and measurement of alpha‑synuclein oligomers—the small protein clusters long suspected of triggering Parkinson’s—in human brain tissue. Using an ultra‑sensitive imaging method, the team found these clusters were larger and more numerous in Parkinson’s than in age‑matched controls, a result published in Nature Biomedical Engineering that may help guide earlier diagnosis and targeted therapies.
New blood test detects HPV-linked cancers up to 10 years early
Reported by AI
Researchers at Mass General Brigham have developed HPV-DeepSeek, a highly sensitive blood test that identifies HPV-associated head and neck cancers nearly a decade before symptoms appear. The test uses whole-genome sequencing to detect viral DNA fragments in the bloodstream. This advance could enable earlier treatments and improve patient outcomes.
Nicotinamide reduces skin cancer risk in veterans study
A large Veterans Affairs study has shown that nicotinamide, a form of vitamin B3, can significantly lower the risk of new skin cancers among patients with a history of the disease. The research, involving over 33,000 veterans, found a 14% overall risk reduction, with even greater benefits for early users. These findings build on a 2015 clinical trial and may influence preventive strategies.
Immune protein promotes arrhythmias after heart attacks
Researchers at Massachusetts General Hospital have identified an immune protein that damages heart cells after a myocardial infarction, leading to dangerous arrhythmias. By targeting this protein in mice, the team reduced arrhythmia incidents twelvefold. The findings suggest new ways to prevent sudden cardiac death.
Toxic alliance of proteins may trigger Alzheimer's disease
Researchers at Rockefeller University have identified a harmful interaction between amyloid beta and fibrinogen that forms stubborn clots, damaging brain blood vessels and sparking inflammation even at low concentrations. This complex disrupts the blood-brain barrier and leads to early signs of neurodegeneration. The findings suggest a new target for early intervention in Alzheimer's disease.
Weaponised CAR T-cell therapy eradicates prostate tumours in mice
Researchers have developed a modified CAR T-cell therapy that completely eliminated large solid prostate tumours in mice, offering hope for treating solid cancers in humans. The approach localises immune-stimulating proteins to tumours, avoiding damage to healthy tissues. Clinical trials could begin within two years.
Glioblastoma erodes skull and disrupts immune system, study reveals
Researchers have discovered that glioblastoma, the most aggressive form of brain cancer, extends beyond the brain by eroding the skull and altering the immune cells in skull marrow. This interaction fuels the cancer's progression and explains why current treatments often fail. The findings, published in Nature Neuroscience, suggest new strategies targeting both brain and bone.
