Physicists wipe away complexity for a clearer view of heavy nuclei
Despite advances in experimental nuclear physics, the most detailed probing of atomic nuclei still requires heavy doses of advanced nuclear theory. The problem is that using theory to make meaningful predictions requires massive datasets that tax even high-powered supercomputers. view more (2007-03-15)

Did comets flood Earth's oceans?
Did the Earth form with water locked into its rocks, which then gradually leaked out over millions of years? Or did the occasional impacting comet provide the Earth's oceans? The Ptolemy experiment on Rosetta may just find out"¦ The Earth needed a supply of water for its oceans, and the comets are large celestial icebergs - frozen... view more... (2004-06-16)
Better measurements reveal seasonal changes in sulfur

Princeton physicists connect string theory with established physics
String theory, simultaneously one of the most promising and controversial ideas in modern physics, may be more capable of helping probe the inner workings of subatomic particles than was previously thought, according to a team of Princeton University scientists. view more (2007-05-03)
ESA's XMM-Newton makes the first measurement of a dead star's magnetism
Using the superior sensitivity of ESA's X-ray observatory, XMM-Newton, a team of European astronomers has made the first direct measurement of a neutron star's magnetic field. The results provide deep insights into the extreme physics of neutron stars and reveal a new mystery yet to be solved about the end of this star's life. A neutron star is... view more... (2003-06-11)
£100 Million For World Leading New Science Project
The UK's world-beating neutron centre at the Rutherford Appleton Laboratory, near Didcot, is to get one of the largest ever awards of Government funding for a single science project, Science Minister Lord Sainsbury announced today. The DTI is giving over £100 million to fund a brand new wing at the ISIS neutron laboratory. This expansion... view more... (2003-04-08)
New forum reinforces plans for neutron source in Scania
An important step has been taken on the way to building the world's most powerful neutron source-ESS-European Spallation Source-in Scania, the southern Swedish province. To strengthen international contacts, not least with the business community, a collaborative group has been established, including members from the Nordic countries and several... view more...

Exoplanets clue to sun's curious chemistry
"For almost 10 years we have tried to find out what distinguishes stars with planetary systems from their barren cousins," says Garik Israelian, lead author of a paper appearing this week in the journal Nature. "We have now found that the amount of lithium in Sun-like stars depends on whether or not they have planets." view more (2009-11-12)
Climate change and the rise of atmospheric oxygen
Today's climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. view more (2006-03-23)
FaME38: Helping engineers studying critical materials
Airplane wings or railway rails are examples of mechanical components constantly submitted to stress. They consist of materials (metal alloys) with properties that may change under stress. To understand and improve such materials, it is essential to observe them on a microscopic scale. The ESRF and the ILL make today a step forward into looking... view more... (2002-11-26)
Physics World Digest: April 2002 edition
Antique dealers turn to physics If you`ve ever wondered if that old Chinese vase in your loft is a genuine antique, physicist Doreen Stoneham could have the answer. She has set up a company - Oxford Authentication - that uses "thermoluminescence" to distinguish a real T`ang dynasty ceramic from a fake. When a tiny amount of material from the... view more...
