At 1.3 million cubic feet, the Goddard Space Flight Center’s High Bay Clean Room, where the components of the James Webb Space Telescope are now being assembled, circulates a staggering one million cubic feet of air per minutes, ensuring no more than 10,000 particles larger than 0.5 microns. Progress on the telescope can now be viewed by webcam.

An analysis of more than 70,000 galaxies by physicists in the U.S. and Switzerland demonstrates that the universe—at least up to a distance of 3.5 billion light years from Earth—plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity.

Today, at the world’s largest supercollider, all of the control rooms will be staffed by women. A brainstorm of Indiana Univ.'s Pauline Gagnon, the event is part of a larger observation of International Women’s Day and a celebration of the accomplishments of women in the highly technical field of high-energy physics.

According to findings by Univ. of Rochester researchers who visited sites in Africa known to contain extremely old rocks, the Earth’s magnetic field 3.5 billion years ago was only half as strong as it is today. This may mean the Sun took away much of Earth’s hydrogen and water.

Scientists from the Functional Materials Group at Kent Univ.'s School of Physical Sciences (SPS) have expanded the potential uses of glass by developing an experimental technique that reveals more clearly how atoms in glass vibrate.

A worldwide team of researchers have for the first time created a particle that is believed to have been in existence immediately after the creation of the universe. The full antinucleus—an antiproton, antineutron, and anti-Lambda particle—is the first to contain an anti-strange quark and represents the first nucleus to drop below the plane in the 3-D Periodic Table of Elements.

Using large-scale supercomputer calculations, researchers have analyzed how the placement of metallic contacts on graphene changes the electron transport properties of the material as a factor of junction length, width and orientation. The work is believed to be the first quantitative study of electron transport through metal-graphene junctions to examine earlier models in significant detail.

A Virginia Tech Engineering Science and Mechanics Professor and his colleague from the Technical Univ. of Denmark shed new light on the chaotic motion of a solid body moving through a fluid.

The uneasy relationship between magnetism and superconductivity is appreciated by physicists—magnetism both creates and destroys superconductors—but is poorly understood. New findings at Brown Univ. show strange sliding waves in superconductors at 10 Tesla. Never before seen by science, the waves may help quantum-level understanding.

Life’s smallest motor, a protein that shuttles cargo within cells and helps cells divide, does so by rocking up and down like a seesaw, according to research conducted by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and Brandeis Univ.
