University of California-Irvine researcher Zhihong Lin is using the Jaguar supercomputer at Oak Ridge National Laboratory to study fusion reactions, which produce helium from hydrogen and release energy in the process, in hopes of igniting ITER, an experimental fusion reactor being built in southern France.

Since the late 20th century, astronomers have been aware of data that suggest the universe is not only expanding, but expanding at an accelerating rate. According to the currently accepted model, this accelerated expansion is due to dark energy, a mysterious repulsive force that makes up about 73% of the energy density of the universe.

It seems impossible: Scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden (Germany) were able to verify with an intermetallic compound of bismuth and nickel that certain materials actually exhibit the two contrary properties of superconductivity and ferromagnetism at the same time.

Bacteria and archaea--collectively known as prokaryotes--live pretty much everywhere, dividing happily in places from stomach acid to deep-sea vents. They can thrive in so many different places because their genomes are incredibly flexible: they can alter, lose and duplicate genes almost at will

If you look at a map of the world and draw a line through London, a latitude of about 50 degrees North and follow this line across the world, you'll see that it passes through southern Siberia and skims the southern shores of Hudson Bay in Canada. The week before I came out to the Catlin Arctic Survey Ice Base, the temperature in Hudson Bay was lurking between -20

(PhysOrg.com) -- "When you pick up a spoon with your fingers, you are able to move it from side to side and rotate it too by moving thumb and forefinger in opposition," Iain Anderson tells PhysOrg.com. Your hand is a soft machine

Quantum mechanical methods can now be used to study gravity: At the Vienna University of Technology (TU Vienna), a measurement method was developed, which allows to test the fundamental theories of physics.

Neutrino beams might create such enigmas, but dare we risk making anything so unpredictable? In "Too Hard for Science?" I interview scientists about ideas they would love to explore that they don't think could be investigated

By Alex Leff PUNTARENAS, Costa Rica (Reuters) - Scientists set off from Costa Rica on Sunday to drill a hole deep under the sea and directly extract rocks from record depths that could add to the understanding of climate change. [More]

I've tried it all: caulking cracks, blowing in insulation, replacing drafty windows and--I'm especially proud of this one--installing a mail-slot cover so airtight it could be used in a space shuttle docking module . Yet my home heating bill remains an object of fear and loathing. After years of trying low-tech solutions, I'm drawn to a high-tech solution, and the one I keep hearing about is the geothermal heat pump.

The traditional view of proteins is that, right after being synthesized, they must fold into a unique shape to function properly. Unstructured proteins, according to biological orthodoxy, are pathological

Legislation on California state Sen. Mark Leno's desk has the potential to affect every household in the U.S.

Proteins are the stuff of life. They are the eyes, arms and legs of living cells
