World’s largest clean room gets a “Webb” cam

World’s largest clean room gets a “Webb” cam

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.

Study validates general relativity on cosmic scale, existence of dark matter

Study validates general relativity on cosmic scale, existence of dark matter

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.

Physicist's idea puts women in control at CERN

Physicist's idea puts women in control at CERN

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.

Oldest measurement of Earth's magnetic field reveals battle between sun and Earth

Oldest measurement of Earth's magnetic field reveals battle between sun and Earth

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 expand the potential uses for glass

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.

Researchers create new antimatter

Researchers create new antimatter

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.

Quantifying the electron transport effects of placing metal contacts onto graphene

Quantifying the electron transport effects of placing metal contacts onto graphene

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.

Understanding chaotic motion of a solid body in a fluid

Understanding chaotic motion of a solid body in a fluid

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.

Physicist discovers odd, fluctuating magnetic waves

Physicist discovers odd, fluctuating magnetic waves

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 carries cell cargo like a seesaw

Life’s smallest motor carries cell cargo like a seesaw

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.

Lunar tires, space MRSA, and resonating microfluidics

Lunar tires, space MRSA, and resonating microfluidics

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.  

A clean energy America…is it coming or not?

A clean energy America…is it coming or not?

Almost a year ago, the buzz during the downturn was that the economic stimulus will help boost jobs in a sort of national improvement program reminiscent of the 1930s. Our coal would be phased out. Our grids would get smart. Our cars would get hybridized.
