Boston-based personal trainer Helena Collins calls the affordable little pedometer “the most effective fitness tool known to man”—or woman. “Becoming aware of how much you move is such motivation to move more,” she says. “Not only for you, but for your whole family. Kids love pedometers—it becomes a family challenge about movement, not exercise.” It also may be fun to track how active (or inactive) you are each day. For starters, 2,000 steps is the equivalent of one mile. To boost your physical and mental health, wear a pedometer and challenge yourself to increase your steps every day.
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.
