Researchers in Israel have achieved a significant global milestone in stem cell technology: they have created the first human embryonic stem cell (hESC) lines that are free of animal contamination and whose production complies with Good Manufacturing Practices (GMP). The achievement paves the way for developing clinical treatments that use hESCs to treat degenerative diseases like age-related mac

Researchers have discovered how a visual prosthetic device could stimulate the brain to generate mental images - the blind person could wear eyeglasses with a tiny webcam that transmits data to a computer chip which is implanted in the brain. The researchers, from the University of Texas Health Science Center and Baylor College of Medicine published their research in the journal Nature Neuroscien
