Physics and Astronomy

New results from research performed at the Department of Energy’s Jefferson Lab hint that strange quarks may contribute to the proton’s magnetic moment. If confirmed by data to be taken later this year, these surprising results would indicate that strange quarks in the proton’s quark-gluon sea contribute to at least one of the proton’s intrinsic properties. The HAPPEx results strengthen the trend found by the SAMPLE experiment at MIT-Bates and the A4 experiment at the Mainz

Lifetime of solar nebual

The oxygen and magnesium content of some of the oldest objects in the universe are giving clues to the lifetime of the solar nebula, the mass of dust and gas that eventually led to the formation of our solar system.

By looking at the content of chondrules and Calcium Aluminum- rich inclusions (CAIs), both components of the primitive meteorite Allende, Lab physicist Ian Hutcheon, with colleagues from the University of Hawaii at Manoa, the Tokyo I

It is widely recognised that cancer affects a large percentage of the population with more than 1 in 3 people being diagnosed with the disease during their lifetime. A lesser known fact is that most of the current diagnostic techniques used for identifying cancer come from technologies

Nanocomposite materials seem to flout conventions of physics. In the latest example of surprising behavior, reported* by scientists at the National Institute of Standards and Technology (NIST) and Brookhaven National Laboratory, a class of nanostructured materials that are key components of computer memories and other important technologies undergo a previously unrecognized shift in the rate at which magnetization changes at low temperatures.

The team suggests that the apparent

Project looked at massive mobile launch platform, shuttle transporter

Sandia National Laboratories recently conducted a series of tests to help NASA understand the fatigue on the space shuttle caused during rollout from the Kennedy Space Center assembly building to the launch pad – a four-mile trip.

The tests are part of NASA’s return-to-flight mission, with the first flight scheduled between May 15 and June 3.

New state of matter more remarkable than predicted — raising many new questions

The four detector groups conducting research at the Relativistic Heavy Ion Collider (RHIC) — a giant atom “smasher” located at the U.S. Department of Energy’s Brookhaven National Laboratory — say they’ve created a new state of hot, dense matter out of the quarks and gluons that are the basic particles of atomic nuclei, but it is a state quite different and even more remarkable than had been predi
