According to Robert Emami, DDS, chief of staff at Dental Specialties, a multispecialty practice in Randolph, Massachusetts, a simple piece of nylon string can have dramatic effects on a woman's overall health. “Flossing is one of the easiest, quickest ways to remove bad bacteria from your body,” he says. “Plaque and bacteria are constantly building up in areas of the teeth that brushing does not get to. If plaque accumulates, it eats away the bone that holds the teeth in place.” Oral bacteria, he adds, can enter the bloodstream; studies have shown that such harmful bugs could exacerbate diabetes and hypertension, and even lead to premature births.
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.
