Researchers at the U.S. Department of Energyâ€™s Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used in magnetic memory technologies. Magnetic switching is used to encode information in hard drives, magnetic random access memory and other computing devices. The discovery, reported in the April 4 issue of Nature, potentially opens the door to terahertz (1012
Materials scientists at the U.S. Department of Energyâ€™s Ames Laboratory are researching ways to perfect a next generation power cable made of an aluminum and calcium composite. Cables of this composite will be lighter and stronger, and its conductivity at least 10 percent better than existing materials for DC power, a growing segment of global power transmission. Its conductivity is about the same as that of existing conductors for AC power.
Pleasant Valley High School of Bettendorf defeated Dubuque Wahlert High School (Dubuque, IA) 74-44 to capture the 2013 Ames Laboratory/Iowa State University Regional High School Science Bowl on Jan. 26. Pleasant Valley, which lost only one match all day in the morning qualifying round, advances to the Department of Energyâ€™s National Science Bowl, April 25-29 in Washington, D.C.
Some of the brightest high school students from across Iowa will travel to Ames on Jan. 26 to compete in the 23rd annual Ames Laboratory/Iowa State University Regional High School Science Bowl. Forty teams of students will compete to answer questions about biology, chemistry, earth and space science, energy, mathematics, and physics in the day-long, quiz-bowl format competition.
