Physics and Astronomy

This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.

innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.

Scientists image tooth decay in the 3rd dimension

A team of scientists from Glasgow today revealed a new technique that will allow dentists to detect and study the tell-tale signs of tooth decay before too much damage is done.

Speaking at one of the opening sessions at the Institute of Physics conference Photon 04 in Glasgow, Simon Poland outlined a new way of making a detailed 3D picture of a diseased area of a tooth, which could be done while a patient waits. Simon Poland, from the Institute of Photonics at the University of St

Tiny meteorite grains help settle an astronomical debate

“These tiny relics, a millionth of a meter small, could point us to the first steps of dust formation in both old and young stars,” stated Dr. Larry Nittler of the Carnegie Institution’s Department of Terrestrial Magnetism. Nittler is co-author of a study published in the September 3, 2004, issue of Science,* about the origin of two presolar grains from the Tieschitz meteorite and the implications they have for resolving observational and theoretical challenges of dusty outflows surrounding

Probable Discovery of a New, Supersolid, Phase of Matter

In the Friday 3 September 2004 issue of Science Express, two physicists from Penn State University will announce new experimental evidence for the existence of a new phase of matter, a “supersolid” form of helium-4 with the extraordinary frictionless-flow properties of a superfluid.

“Solid helium-4 appears to behave like a superfluid when it is so cold that the laws of quantum mechanics govern its behavior,” says Moses H. W. Chan, Evan Pugh Professor of Physics at Penn State. “One of

The Grid becomes a reality

This week, UK particle physicists have demonstrated the world’s largest, working computing Grid. With over 6,000 computers at 78 sites internationally, the Large Hadron Collider Computing Grid (LCG) is the first permanent, worldwide Grid for doing real science. The UK is a major part of LCG, providing more than 1,000 computers in 12 sites. At the 2004 UK e-Science All Hands Meeting in Nottingham, particle physicists representing a collaboration of 20 UK institutions will explain to biolog

Yellow Glasses To Save Vision

Blue light destroys certain structural elements in the eye, as was revealed by the Russian research team. The mechanism of this effect was studied, and protective measures were offered. The work was supported jointly by the Russian Foundation for Basic Research (RFBR) and the Foundation for Assistance to Small Innovative Enterprises (FASIE), project no. 02-04-08012.

Frankly, the results arising from the long-term study conducted by the team headed by Academician Michael Ostrovsky are

The Sun’s X-file under the Spotlight

One of the Sun’s greatest mysteries is about to be unravelled by UK solar astrophysicists hosting a major international workshop at the University of St Andrews from September 6-9th 2004. For years scientists have been baffled by the ’coronal heating problem’: why it is that the light surface of the Sun (and all other solar-like stars) has a temperature of about 6000 degrees Celsius, yet the corona (the crown of light we see around the moon at a total eclipse) is at a temperature of
