Scientists have genetically programmed embryonic stem cells to become nerve cells when transplanted into the brain, according to a new study. The research, an important step toward developing new treatments for stroke, Alzheimer's, Parkinson's and other neurological conditions showed that mice afflicted by stroke showed therapeutic improvement following transplantation of these cells. None of the mice formed tumors, a major setback in prior attempts at stem cell transplantation.

Oral cannabis (a form of medical marijuana) not only failed to alleviate certain types of pain in human volunteers but, surprisingly, it instead caused increased sensitivity to some forms of pain. Researchers evaluated the analgesic potency of orally administered cannabis extract that included its main psychoactive component, Tetrahydrocannabinol (THC).

Researchers have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease. When the brakes fail, dementia results. This discovery could open the door to new ways of treating Alzheimer's disease, which affects up to half the population over the age of 85.
