Quantum leap for entanglement
Most methods for generating entangled states rely on selecting the entangled pairs, for instance, from a large number of other non-entangled particles. However, last year Klaus Mølmer and Anders ...
Physics get physical
For ‘short’ races the average speed of a world-record performance declines sharply with increasing distance. However, above a certain distance, the decline is more gentle. For both running...
How to keep your optical fibres clear and dry
Thomas’s group measured the spatial distribution of water in the glass rods from which the optical fibres are drawn. They discovered that water diffuses into the molten, flowing glass much faste...
New synchrotron will be built at Rutherford
Construction of the new synchrotron is expected to take about five years, and it will cost about £550 m to build and operate the machine over its 20 year lifetime. The Wellcome Trust will contrib...
Astronomers check out the far side of the Sun
Charles Lindsey of the Solar Physics Research Corporation in Arizona and Douglas Braun of Northwest Research Associates in Colorado used data from a Doppler imager on the Solar Heliospheric Observator...
ESA gets flexible
The three space science missions are: STORMS, a set of three spacecraft that will be used to monitor magnetic storms in space; SOLAR ORBITER, a mission to study the surface and atmosphere of the Sun i...
Burning mystery remains
The group studied three different weights of paper in their experiments. Sheets of paper were place in a combustion chamber and lit by an electric wire. The propagating front of the fire was recorded ...
Fractional effects in nanotubes explained
The quantum of conductance, G0, is defined by a simple equation: G0=2e2/h, where e is the charge on the electron and h is the Planck constant. The conductance of an individual nanotube is predicted to...
New technique promises cheaper photonic crystals
The method works by solidifying a resin that hardens when exposed to light. The resin is solidified into a three-dimensional grid by placing it in the interference pattern set up by four intersecting ...
World order upset by new citation study
Using citation data from the Institute for Scientific Information in Philadelphia, Katz has found that there is in fact a power-law or “fractal” relationship between the number of citation...
