Quantum dots detect single photons
The quantum dot device consists of a transistor made of different layers of gallium arsenide and aluminium gallium arsenide. One of the layers consists entirely of quantum dots just nanometers across....
New tools for X-rays
Klaus Dieter Liss from the European Synchrotron Radiation Facility in Grenoble, France, and colleagues have created a cavity that traps X-ray photons between two thin plates of silicon (Nature 404 371...
New head for ESRF
Stirling is no stranger to Grenoble, having worked at the nearby Institut Laue-Langevin (ILL) neutron source for 14 years, and later chairing the ILL scientific council. He currently uses X-rays from ...
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...
NAUTILUS detects cosmic rays
NAUTILUS was designed to observe the gravitational waves produced by collisions between objects such as black holes or neutron stars. According to the Frascati’s group calculations, signals from...
XMM launches
XMM will be in a highly elliptical orbit to keep it away from interference caused by the Sun’s glare. The telescope’s large size and unusual orbit explains why XMM was launched from Ariane...
Brookhaven neutron source to close
The HFBR had become trapped in a economic and political battle between the Department of Energy and the US congress, with the latter refusing to release funds to restart the reactor. Moreover, it was ...
NASA plans astrometric mission
Like ESA’s recent Hipparcos mission, FAME will use the parallax method to determine the stars’ positions: as the telescope and the Earth orbit the sun, the position of the stars will chang...
France joins UK synchrotron project
The UK synchrotron, once known as Diamond, is intended to replace the ageing second-generation SRS machine at the Daresbury Laboratory in Cheshire, although the location of the new machine has still t...
Physicists prove Van Gogh painting is not a forgery
Scientists at the research laboratory of the Museums of France in Paris compared the painting with nine of the 70 works accredited to Van Gogh during his time at Auvers. However, they were not allowed...
