Atom interferometer provides most precise test yet of Einstein's gravitational redshift
(22 Feb 2010)
Scientists measure interference between matter waves separated by 0.1 mm
While airplane and rocket experiments have proved that gravity makes clocks tick more slowly – a central prediction of Albert Einstein's general theory of relativity – a new experiment in an atom interferometer measures this slowdown 10,000 times ...

'NanoPen' may write new chapter in nanotechnology manufacturing
(04 Sep 2009)
Researchers in California are reporting development of a so-called "NanoPen" that could provide a quick, convenient way of laying down patterns of nanoparticles - from wires to circuits - for making futuristic electronic devices, medical diagnostic ...

World's smallest semiconductor laser heralds new era in optical science
(01 Sep 2009)
Researchers at the University of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.This ...

Exploring the standard model of physics without the high-energy collider
(12 Aug 2009)
Scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory in the US, have performed sophisticated laser measurements to detect the subtle effects of one of nature's most elusive forces - the "weak interaction". ...

Tunable semiconductors possible with hot new material called graphene
(12 Jun 2009)
Today's transistors and light emitting diodes (LED) are based on silicon and gallium arsenide semiconductors, which have fixed electronic and optical properties. Now, University of California, Berkeley, researchers have shown that a form of carbon ...

A billion-year ultra-dense memory chip
(11 Jun 2009)
When it comes to data storage, density and durability have always moved in opposite directions – the greater the density the shorter the durability. For example, information carved in stone is not dense but can last thousands of years, whereas ...

Biomass the new petroleum?
(20 May 2009)
Biomass-derived carbohydrates convert to alkenes using a one-pot technique that could lead to biomass refinery processes, say scientists in the US.Alkenes are extensively used in industry, but at present they are derived almost exclusively from ...

Carbon rising from the flames
(18 Mar 2009)
Scientists in the US offer new insights into how polycyclic aromatic pollutants are formed in flames and other combustion processes.Peter Vollhardt and colleagues from the University of California, and William Karney from the University of San ...

Cracking a controversial solid state mystery
(10 Feb 2009)
Scientists can easily explain the structural order that makes steel and aluminium out of molten metal. And they have discovered the molecular changes that take place as water turns to ice. But, despite the fact that glass blowers have been plying ...
