Researchers have pinpointed a human gene product that helps regulate wound healing and may control scarring in people recovering from severe injuries and damage to certain internal organs. The protein, MG53, travels throughout the bloodstream […]
Researchers who are developing miniature models of human organs on plastic chips have touted the nascent technology as a way to replace animal models. Although that goal is still far off, it is starting to […]
When you look at a bicycle, says MIT’s José Gómez-Márquez, you immediately understand how it works. Whether it costs £10 or £10,000, the underlying mechanisms are easily understood, and such a design allows it to be […]
