Scratching an itch can feel really satisfying, but unfortunately, it might not be the best idea. Ever wondered why we have the urge to scratch an itch even though it makes things worse? Scientists at a university in Pittsburgh wanted to figure out this mystery. They conducted expe
These are not good times for the wild bison of Wood Buffalo National Park in northern Canada. Since the 1920s, when infected bison were introduced, these animals have been grappling with a serious health issue: bovine tuberculosis (BTB). This disease, brought on by a certain bacteria called Mycobac
Semiconductors are tiny but powerful, powering everything from smartphones to supercomputers. They are used in nearly every electronic device we use. However, making these semiconductors can be tough on the environment. The specialty materials used in their production can be harmful if not managed p
Picture this: Bacteria living in your mouth and gut might be pulling the strings behind strokes. A recent study put two groups under the microscope: 189 people who had strokes and 55 who hadn't. The study found that one particular bacteria, Streptococcus anginosus, was hanging out way more in the s
Picture this: you're trying to balance a seesaw, but one side is super heavy, and the other is super light. That's the challenge scientists face with zinc-air batteries. The key is to balance two important processes: oxygen reduction and oxygen evolution reactions. These reactions happen when the ba
Scientists have been facing challenges when trying to use gut bacteria data to detect colon cancer. While powerful sequencing tools give us loads of information, the data often turns out messy and tough to decipher. Both traditional methods and smart algorithms struggle to get clear answers from thi
Let's talk about women's health for a bit. Women face a lot of unique challenges throughout their lives, thanks to biological, societal, and healthcare factors. These issues have led to some big gaps in health between men and women. For instance, diseases that mainly affect women often get less atte
Are you tired of surfaces that get dirty easily? Science is cooking up a solution! Researchers have found a way to create super-water-repelling surfaces that can keep themselves clean. They're using something called MCM-41 and tweaking it with a bit of aluminum to make it even better. This new surfa
Two-photon polymerization, or TPP, is a fascinating manufacturing technique gaining traction in the biomedical field. Unlike other methods, TPP can create 3D structures with incredible precision, down to the nanometer scale. What makes TPP so special is its ability to provide free-form fabrication.
Menthol is a natural substance found in peppermint and corn mint oils. It's widely used in medicines, cosmetics, and food. Out of the eight forms of menthol, (-)-menthol is the most effective at giving a refreshing feeling. Scientists have long known that (-)-menthol feels cooler and more refreshing
