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.
Online brain training tied to decade‑equivalent boost in cholinergic function, McGill trial finds
Heather Vogel तथ्य-जाँच किया गया
A double‑blind McGill University–led clinical trial reports that 10 weeks of BrainHQ exercises increased a PET marker of cholinergic function in healthy older adults by an amount the authors say roughly offsets about a decade of age‑related decline. The peer‑reviewed study used a specialized tracer to confirm the biochemical change.

Bananas may reduce flavanol absorption in smoothies, UC Davis-linked study finds
Heather Vogel AI द्वारा उत्पन्न छवि तथ्य-जाँच किया गया
A small UC Davis–affiliated trial reports that a banana-based smoothie markedly lowered the body’s uptake of flavan-3-ols—about 84% less at peak plasma levels than after a control capsule—an effect the researchers link to the fruit’s polyphenol oxidase enzyme.
Lancet review questions gluten as main driver of most ‘gluten sensitivity’ symptoms
Heather Vogel तथ्य-जाँच किया गया
A University of Melbourne–led review published in The Lancet on October 22, 2025, argues that many symptoms attributed to non‑coeliac gluten sensitivity are more often linked to FODMAPs, other wheat components, and gut–brain interactions than to gluten itself. The authors call for better diagnostics, individualized care, and a shift away from unnecessary gluten avoidance.
UCSF researchers test LSD-based MM120 for generalized anxiety disorder
Heather Vogel AI द्वारा उत्पन्न छवि तथ्य-जाँच किया गया
UCSF neuroscientist Jennifer Mitchell and collaborators are evaluating MM120, a pharmaceutical form of LSD, as a potential treatment for generalized anxiety disorder. A randomized clinical trial published in JAMA found that a single dose reduced anxiety symptoms versus placebo, with benefits persisting up to 12 weeks in the optimal dose group, according to the study and the drug’s sponsor.
Woman dies in São Vicente after consuming alcoholic drink
A 32-year-old woman died in São Vicente, on the coast of São Paulo, after falling ill from consuming an alcoholic drink at a bar. Police are investigating possible methanol poisoning amid a crisis that has caused 15 deaths in Brazil. The establishment was shut down for lacking a permit.
Scientists uncover hidden antibiotic intermediate 100-fold more active than methylenomycin A
Heather Vogel AI द्वारा उत्पन्न छवि तथ्य-जाँच किया गया
Researchers from the University of Warwick and Monash University report that pre-methylenomycin C lactone—an overlooked biosynthetic intermediate from Streptomyces coelicolor—shows more than a 100-fold increase in activity over methylenomycin A against Gram‑positive pathogens, including those behind MRSA and VRE. The finding adds momentum to efforts to tackle antimicrobial resistance, which was directly linked to an estimated 1.27 million deaths in 2019.
Protamine shortage suspends open-heart surgeries in private clinics
A shortage of protamine, an essential drug to reverse heparin's effects in heart surgeries, has forced private clinics in Chile to suspend elective procedures. The scarcity stems from issues with the sole registered supplier, BPH S.A., which is struggling to release batches of the medication. While the public sector reports no suspensions, private institutions urgently seek state support.
Randomized trial finds certain processed hard fats did not worsen short-term heart risk markers

A small randomized crossover study found no meaningful differences in cholesterol or other short‑term cardiometabolic markers when healthy adults consumed either palmitic‑rich or stearic‑rich interesterified fats for six weeks apiece.
Cognitive ability tied to understanding speech in noisy settings, study finds

Among people with clinically normal hearing, intellectual ability strongly predicted how well they understood speech amid competing voices, according to a peer-reviewed study from University of Washington researchers.
COVID-19 mRNA vaccines linked to longer survival in some lung and skin cancer patients on immunotherapy
Heather Vogel तथ्य-जाँच किया गया
A large retrospective study from the University of Florida and The University of Texas MD Anderson Cancer Center, published in Nature, reports that patients with advanced non-small cell lung cancer or metastatic melanoma lived significantly longer if they received a Pfizer-BioNTech or Moderna COVID-19 mRNA shot within 100 days of starting immune checkpoint inhibitors. The authors stress the findings are observational and will require confirmation in randomized trials.
Men over 50 need more exercise than women for heart benefits
A new study reveals that men over 50 must exercise nearly twice as much as women to achieve similar reductions in coronary heart disease risk. Using data from activity trackers, researchers found significant sex differences in exercise benefits for heart health. The findings suggest a need for updated, gender-specific health guidelines.
