Every time you see a slippery rock in a stream or a slimy hull on a boat, you’re looking at biofilms—thin layers of microbes stuck to surfaces. These microscopic communities don’t just stick around by accident. They produce special proteins called adhesins, especially at one end of the cell, to glue
Scientists have made a new family of tiny sugar molecules that can form glowing gels in many different liquids.

A patient with a body mass index of 45. 8, which is considered severe obesity, began an intensive program focused on diet, exercise and behavior change. Over the course of several months, she managed to lower her BMI to 31. 7, a level that is still overweight but far closer to the healthy range. Thi
Bitcoin has begun to prove itself as an asset that can move freely across borders, especially when global tensions rise.
