Brain May Be Less Plastic Than Hoped

...milar studies could one day show scientists how to help the brain to recover from injuries. “In humans, studying brain reorganization is difficult. Cortical injuries are not happening in a controlled fashion, and resulting data consequently are difficult to interpret,?he said. “But in the macaque, you can...

Some months later, the same species wa...

Two chemicals boost immune cells' ability to fight HIV without gene therapy

...udy has discovered that two chemical compounds may help the immune systems of HIV-infected persons fight the disease without invasive gene therapy. Presented March 5 at the 2005 Palm Springs Symposium on HIV/AIDS, the new research demonstrates that the new chemicals activate telomerase -- a protein that b...
