Oct 23, 2009Recording fine-grained electrical activity seems to predict a person’s responsiveness to one common drug, in an early trial. Oct 15, 2009Two studies outline ambitious methods to coax growth from nerve fibers after spinal cord injury, but also highlight the difficulty of getting around the body’s roadblocks to new nerve formation. Oct 08, 2009Walter G. Bradley explains why he thinks everyone should read his new book, why finding the right doctor is essential and how the Internet is changing the doctor-patient relationship. Oct 07, 2009Two years after the first human iPS stem-cell lines were created by reprogramming skin cells, researchers have developed lines covering more than 20 human diseases. These lines are helping scientists watch how disease changes cells in real time as well as investigate drugs to combat disease. Oct 02, 2009Doctors may soon be using a variety of brain scans to diagnose and treat Alzheimer’s long before major symptoms appear. Several new studies add to evidence that scanning technology is powerful enough to detect minor brain changes that appear early in the course of the disease. Oct 01, 2009Scientists are finding that leptin, the hormone that helps amplify feelings of fullness, may also alter pleasure pathways, in a finding that may pave the way for new obesity treatments. Sep 29, 2009Huntington’s disease appears to have destroyed, within a decade, grafts of neural tissue given to patients, a finding that adds to evidence that neurodegenerative diseases are less amenable to transplantation treatments than was once thought.

Sep 10, 2009Strengthening the immune system’s ability to destroy harmful proteins and reducing harmful inflammation once damage does occur both offer promising approaches against Alzheimer’s, according to several recent studies. |
