Best of Last Week: Acoustic phonons have magnetic properties, universe to collapse and bioclock disruption problem

It was another good week for physics as researchers at Ohio State University conducted a landmark study that proved that magnets can control heat and sound—they demonstrated a magnetic field reducing the amount of heat flowing through a semiconductor, proving that acoustic phonons have magnetic properties. In another study, a combined team of researchers from the University of Belgrade and MIT revealed a technique they had developed that allowed for entangling 3,000 atoms using a single photon, representing a new milestone in the number of particles that have been entangled at one time. Also a team of researchers at Griffith University ran an experiment that demonstrated entanglement of a single particle—showing that the collapse of the wave is a real effect. —> Read More
