Spinach to fuel optoelectronics
Although they are only 5nm long, each complex can generate 1 V in picoseconds, making them suitable for ultrafast switching, logic devices, and solar-power generation. The work was presented this week...
Gravity-wave detectors target quantum gravity
Both the French-Italian gravity-wave interferometer, called VIRGO, and the LIGO interferometers in the US are designed to detect very weak gravity waves by using lasers to monitor test masses placed a...

Matter makes waves
Phillips and his colleagues produced a focused directional output from the Bose-Einstein condensate by firing two laser beams into the condensate. One beam adds energy to the atoms, while the second s...
Solar system is chaotic
Murray and Holman ran numerical simulations of the planets positions over a 200 million year period using their new technique. They discovered that although the outer planets appear in stable orbits, ...
US dominates world patents
The National Science Foundation report also discovered that the US, Russia and Japan have the lowest number of patents awarded to foreign inventors. In all the other countries surveyed, over two-third...
How to predict solar flares
Richard Canfield and David McKenzie from Montana State University in the US, and Hugh Hudson from the Solar Physics Research Corporation in Japan, analysed two years worth of images from the X-ray sat...
Quantum wells go metallic
Tai Chang Chiang and co-workers at Urbana confined electrons in thin films of silver ranging from 1 monolayer to around 100 monolayers thick. Just as photons resonate back and forth in an optical Fabr...
CERN and Fermilab argue over “new” discovery
Last Monday Fermilab issued a press release titled “Fermilab physicists find new matter-antimatter asymmetry”. On Thursday CERN replied with a statement which read: “The CERN physics...
New director for Fermilab
Witherell received his PhD from the University of Wisconsin in 1973 and became an assistant professor at Princeton University in 1975. He moved to Santa Barbara in 1981 and in 1990 won the American Ph...
