Physicists add amplifier to quantum communication toolbox

Quantum encryption using single photons is a promising technique for boosting the security of communication systems and data networks, but there are challenges in applying the method over large distances due to transmission ...

Nano-notch sends self-assembling polymers into a spiral

A simple circular or hexagonal pit written into silicon can be used to generate self-assembling polymer spirals thanks to the addition of a tiny notch in the template, report scientists in the launch issue of Nano Futures.

Liquid breathing moves a step closer thanks to measurement study

Liquid ventilation –breathing a liquid instead of air – has long been the stuff of science fiction, and despite experimental clinical use, its potential for treating severe pulmonary or cardiac trauma, and use in deep ...

Physics explains why rock musicians prefer valve amps

For many guitarists, the rich, warm sound of an overdriven valve amp – think AC/DC's crunchy Marshall rhythm tones or Carlos Santana's singing Mesa Boogie-fuelled leads – can't be beaten.
