Physicists create new 3D microchip

Scientists from the University of Cambridge have created, for the first time, a new type of microchip which allows information to travel in three dimensions. Currently, microchips can only pass digital information in a very ...

Steps towards filming atoms dancing

With their ultra short X-ray flashes, free-electron lasers offer the opportunity to film atoms in motion in complicated molecules and in the course of chemical reactions. However, for monitoring this motion, the arrival time ...

NASA's new way to track formaldehyde

NASA scientist Tom Hanisco is helping to fill a big gap in scientists' understanding of how much urban pollution -- and more precisely formaldehyde -- ultimately winds up in Earth's upper atmosphere where it can wreak havoc ...

Reanalyses find rising humidity in the Arctic

(Phys.org) -- Direct, reliable observations of atmospheric conditions stretch as far back as the mid seventeenth century, with otherwise consistent records being punctuated by periodic updates in methods, practitioners, and ...

A new generation of acoustic measurements

NPL scientists have made the first measurements of airborne acoustic free-field pressures using a laser technique based on photon correlation spectroscopy.

Quantum copies do new tricks

One of the strange features of quantum information is that, unlike almost every other type of information, it cannot be perfectly copied. For example, it is impossible to take a single photon and make a number of photons ...
