Ultraviolet portion of sunlight may play bigger role in controlling MS: Study

For more than 30 years, scientists have known that multiple sclerosis (MS) is much more common in higher latitudes than in the tropics. Because sunlight is more abundant near the equator, many researchers have wondered if the high levels of vitamin D engendered by sunlight could explain this unusual pattern of prevalence.

Researchers use optogenetics technology to troubleshoot neural circuits

Recently, brain researchers have gained a powerful new way to troubleshoot neural circuits associated with depression, Parkinson's disease and other conditions in small animals such as rats. They use an optogenetics technology, invented at Stanford University, that precisely turns select brain cells on or off with flashes of light. Although useful, the optogenetics tool set has been limited.

Research paves way for building tabletop X-ray laser that can be used for high-resolution imaging

For nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized X-ray laser that could, among other things, provide super high-resolution imaging. And for the past two decades, University of Colorado at Boulder physics professors Margaret Murnane and Henry Kapteyn have been inching closer to that goal.
