Fingerprint makes chips counterfeit-proof
— 9 Feb 2011 17:08 | TechnologyProduct piracy long ago ceased to be limited exclusively to the consumer goods sector. Industry, too, is increasingly having to combat this problem. Cheap fakes cost business dear:…
New wave: Spin soliton could be a hit in cell phone communication
— 16 Sep 2010 05:19 | TechnologyResearchers at the National Institute of Standards and Technology (NIST) have found theoretical evidence of a new way to generate the high-frequency waves used in modern communication…
NIST sensor measures yoctonewton forces fast
— 2 Sep 2010 17:16 | TechnologyPhysicists at the National Institute of Standards and Technology (NIST) have used a small crystal of ions (electrically charged atoms) to detect forces at the scale of yoctonewtons.…
New method developed for synchronising clocks
— 21 Jul 2010 07:33 | TechnologyMaintaining the correct time is no longer just a matter of keeping your watch wound - especially when it comes to computers, telecommunications, and other complex systems. The clocks…
Oscillations at odds in the heart
— 15 Mar 2010 15:50 | HealthResearchers in Germany show that a classical biological oscillator, the glycolytic oscillator, may increase damage to the heart during acute loss of oxygen (anoxia), and as may occur…
UC San Diego researchers synchronise blinking 'genetic clocks'
— 21 Jan 2010 14:54 | BiologyResearchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step…
NIST physicists demonstrate quantum entanglement in mechanical system
— 4 Jun 2009 01:45 | PhysicsPhysicists at the National Institute of Standards and Technology (NIST) have demonstrated entanglement - a phenomenon peculiar to the atomic-scale quantum world - in a mechanical system…
Atomic fountain clocks are becoming still more stable
— 19 Mar 2009 12:20 | PhysicsCaesium fountains are more accurate than 'normal' atomic caesium clocks, because in fountains the caesium atoms are cooled down with the aid of laser beams and come ever slower - from…
New X-ray source could be brightest in the world
— 22 Jun 2008 12:30 | TechnologyThe future of high-intensity X-ray science has never been brighter now that scientists at U.S. Department of Energy's Argonne National Laboratory have devised a new type of next generation…
Atomic laser light cools microchip
— 14 Apr 2008 11:23 | PhysicsMacroscopic objects follow the laws of classical physics, microscopic objects obey the laws of quantum mechanics. This is for sure. But at what point does a system stop to behave classically…
