Scientists at the University of Bath have developed a simple three-minute brainwave test called Fastball EEG that can detect memory problems years before Alzheimer’s is typically diagnosed. Unlike traditional memory tests, it passively records brain responses to images and has now been proven effective in people’s homes. With breakthrough Alzheimer’s drugs working best in early …

Thousands of women are using GLP-1 drugs like Ozempic for weight loss without contraception, leading to unintended pregnancies and potential risks for unborn babies. Experts warn clearer medical guidance is urgently needed. ​Thousands of women are using GLP-1 drugs like Ozempic for weight loss without contraception, leading to unintended pregnancies and potential risks for unborn …

Overactivation of dopamine neurons may directly drive their death, explaining why movement-controlling brain cells degenerate in Parkinson’s. Mice with chronically stimulated neurons showed the same selective damage seen in patients, along with molecular stress responses. Targeting this overactivity could help slow disease progression. ​Overactivation of dopamine neurons may directly drive their death, explaining why movement-controlling …

Scientists have decoded the 3D structure of an ancient viral protein hidden in our DNA. The HERV-K Env protein, found on cancer and autoimmune cells, has a unique shape that could unlock new diagnostics and therapies. ​Scientists have decoded the 3D structure of an ancient viral protein hidden in our DNA.

Past climate assessments let big polluters delay action, placing more burden on smaller nations. A new method based on historical responsibility demands steep cuts from wealthy countries and more financial support for poorer ones. Courts are now stepping in, making climate justice not just political but also legal. ​Past climate assessments let big polluters delay …
