Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered that applying vibrational motion in a periodic manner may be the key to preventing dissipations of the desired electron states that would make advanced quantum computing and spintronics possible (npj Quantum Materials, « Light Control of Surface-Bulk Coupling by Terahertz Vibrational Coherence in a Topological Insulator »).

When a person gets sick, the invading virus or bacteria often triggers an immune response, sending a wave of white blood cells to attack the source of the illness. While the body’s natural defenses can often dismantle the infection, the immune reaction can sometimes cause more harm than intended.
