Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered the relaxation dynamics of a zero-field state in skyrmions, a spinning magnetic phenomenon that has potential applications in data storage and spintronic devices.
Iowa's top science and math students will face-off here on Jan. 26 in an intense question and answer competition in the 29th annual Ames Laboratory/Iowa State University Regional High School Science Bowl. Forty teams of students will compete to answer questions that test their knowledge of biology, chemistry, Earth and space science, energy, mathematics, and physics in the day-long, quiz-bowl format competition.
Much of the growing global concern about the plastics polluting our oceans and clogging our landfills has focused on reducing consumption and reusing where we can. But there’s a reason manufacturers and consumers struggle to substitute other materials-- for many uses, plastics are simply the best material available. When it comes to keeping our food and drugs clean and uncontaminated and our medical procedures reliably sterile and safe, the one-use-only disposability of plastics has been essential to our health.
A team of experimentalists at the U.S. Department of Energy’s Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.
