(Medical Xpress)—A group of researchers in Austria and Switzerland has for the first time proven that immune cells migrate along chemical concentration gradients. This process has long been assumed but never demonstrated ...
About 20 years ago, scientists discovered the gene that causes Huntington's disease, a fatal neurodegenerative disorder that affects about 30,000 Americans. The mutant form of the gene has many extra DNA repeats in the middle ...
