New therapy uses synthetic nanofibers to mimic the natural signaling of a protein that is crucial for cartilage formation and maintenance. Researchers found that intensifying the motion of molecules within the nanofibers led to more components needed for regeneration. After just four hours, the treatment activated the gene expression necessary to generate cartilage. Therapy could be used to treat osteoarthritis, which affects nearly 530 million people worldwide.
Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out of a moving car? Flies aren't just reacting to an odor with a preprogrammed response:…
