Chronic inflammation may leave lasting marks on gut stem cells and help explain higher colorectal cancer risk — but the evidence provided here is not enough to confirm the link Few ideas are more important in cancer biology than this one: tumours do...
Continue readingDifferences in brain gene activity may help explain why some disorders affect men and women differently Few questions in neuroscience are as important — or as easy to oversimplify — as why some brain disorders affect men and women differently. For de...
Continue readingSongbird brains can generate new neurons — but that does not prove the human brain does the same on a similar scale Few ideas in neuroscience are as captivating as the possibility that the adult brain can continue generating new neurons. For a long t...
Continue readingAn AI tool could help flag intimate partner violence risk — but the promise still depends on stronger evidence and strict ethical safeguards Few areas of health care demand as much sensitivity as intimate partner violence. The problem often remains h...
Continue readingOlder mice may reveal what young models miss about cancer and ageing In biomedical research, the ideal experimental model is often described as controlled, reproducible, and standardised. That is one reason cancer studies have long relied heavily on...
Continue readingBrain ‘noise’ may not be noise at all — and overlooked signals could help refine mental-health biomarkers In brain imaging, few assumptions have seemed more intuitive than this one: if a signal fluctuates too much, varies too widely, or looks unstabl...
Continue readingA new hypothesis suggests pesticide residues could affect lung-cancer risk in younger non-smokers — but there is not enough evidence here to blame healthy diets Few health headlines create confusion as quickly as ones that seem to reverse basic preve...
Continue readingNew study looks at stigma towards women who lose weight with GLP-1 drugs — and suggests weight loss is still judged as a moral issue, not only a medical one Few health topics expose social judgement about the body as clearly as obesity. And few recen...
Continue readingRobotic or laparoscopic surgery may work for gallbladder cancer — but only in carefully selected patients and experienced centres Few digestive cancers demand as much surgical caution as gallbladder cancer. It is a relatively uncommon disease, often...
