Measuring flow using a tiny wobbling tube

One milligram per hour: fluid flow can be measured with great precision using a tiny 'wobbling' tube with a diameter of only 40 micrometres. Thanks to a new technique, the sensor, which makes use of the 'Coriolis effect', can be made even more compact.

Synchronized nanoscale oscillators may spur new devices

Synchronization phenomena are everywhere in the physical world - from circadian rhythms to side-by-side pendulum clocks coupled mechanically through vibrations in the wall. Researchers have now demonstrated synchronization at the nanoscale, using only light, not mechanics.

Physicists make strides in understanding quantum entanglement

Using computers to calculate the extreme version of quantum entanglement - how the spin of every electron in certain electronic materials could be entangled with another electron's spin - the research team found a way to predict this characteristic. Future applications of the research are expected to benefit fields such as information technology.
