For decades, the enormous disease-curing potential of human stem cells has been thwarted by the inability to produce sufficient quantities of mature human cells in vivo — in a living organism. Now, a team led by University at Buffalo scientists has developed a method that dramatically ramps up the production of mature human cells in...
by Bob Yirka , Medical Xpress team of researchers from several institutions in the U.S. has found a link between the onset of chronic back pain and changes to the nucleus accumbens in the brain. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of volunteers with...
Research has shown that light is important for more than just vision—it directly impacts mood and learning. In a new study, researchers at the National Institute of Mental Health (NIMH) traced the brain pathways responsible for the effects of light on learning and mood. The findings revealed that these effects are brought about by two...
Cells in the eye are key to regulating humans’ circadian rhythm, according to a scientific study. Researchers at the University of Edinburgh found that a group of cells in the retina communicate directly with the region of the brain that deals with the body’s internal clock. All life forms respond to the daily light-dark changes...
