A research team from Tohoku University, Shin-Etsu Chemical Co., Ltd., and École Polytechnique Fédérale de Lausanne (EPFL) has invented a new way to efficiently guide spin waves around sharp corners with minimal loss—representing an exciting discovery for energy-efficient computing. Using a two-dimensional magnonic crystal—a copper (Cu) film with a hexagonal array of tiny holes placed […]

In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism, which converts the gravitational energy of the weights into impulses that drive the pendulum, which then moves the clock’s gears, which […]

Honeycombs are famous for their elegant design, but now they may have found a new application: quantum computing. To collect knowledge from subatomic particles, quantum computers require carefully designed materials capable of performing necessary, complex functions. However, the metals used, such as ruthenium and iridium, are often rare and expensive, limiting the potential to build […]

Researchers in Spain have discovered that in collectives of moving fire ants, rippling “waves” of density and activity are likely triggered by local regions where ants collectively travel in the same direction as their neighbors.
