A routine blood marker tied to inflammation may reveal Alzheimer’s risk years in advance. Scientists found that higher neutrophil levels—part of the body’s first immune response—were linked to a greater chance of developing dementia. The discovery suggests this common lab value could help flag at-risk individuals before symptoms appear. It also raises the possibility that immune cells themselves may be fueling the disease.

A new minimally invasive procedure may help people keep weight off after stopping popular drugs like Ozempic and semaglutide—something most patients struggle with. In a clinical trial, those who underwent a technique called duodenal mucosal resurfacing regained far less weight compared to others after discontinuing the medication. The procedure works by renewing the lining of the upper small intestine, potentially “resetting” metabolism and preserving the benefits of weight loss.

Scientists have identified two specific types of brain cells that behave differently in people with depression, offering a clearer picture of what is happening inside the brain. By analyzing donated brain tissue with advanced genetic tools, the researchers found changes in neurons linked to mood and stress, as well as in immune-related microglia cells. These differences point to disruptions in key brain systems and reinforce that depression is rooted in biology, not just emotions.

A new virus-fighting plastic film could transform everyday surfaces into invisible defenders against disease. Instead of relying on chemicals, this flexible material is covered in microscopic pillars that physically stretch viruses until they burst, rendering them harmless. In lab tests, it destroyed or disabled about 94% of virus particles within an hour, showing impressive effectiveness.
