Next time you’re at the doctor’s office, request a simple blood test to evaluate your vitamin D blood levels, suggests Doreen Orion, MD, a physician in private practice in Boulder, Colorado, and the author of the memoir Queen of the Road. “We're finding that many, many women have a low level of this essential vitamin,” she says. “Low levels are correlated with all sorts of things from cancers to low energy to Alzheimer's. I've had patients who are outside all day, who still have very low levels. The fix is simple and just involves taking vitamin D for several months, then rechecking the level.”
Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. The new discovery, made by researchers at Oregon State University, the University of Iowa and Philipps University in Germany, has identified a way in which nanoscale devices based on gallium arsenide can respond to strong terahertz pulses for an extremely short period, controlling the electrical signal in a semiconductor. The research builds on previous findings for which OSU holds an issued patent.
