Ancient tropical rocks that now reside in the remote northern reaches of Canada tell the tale: about 716.5 million years ago the Earth lay bound in a layer of ice that limited life to eukaryotes. Strangely, this glaciation—history’s most extensive at 5 million years, say researchers at NSF and Harvard—occurred at about the same time that animals appear in the fossil record.

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.

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.

For decades, the traditional practice in animal testing has been standardization, but a study involving Purdue Univ. has shown that adding as few as two controlled environmental variables to preclinical mice tests can greatly reduce costly false positives, the number of animals needed for testing and the cost of pharmaceutical trials.

A recent discovery in understanding how to chemically break down the greenhouse gas carbon dioxide into a useful form opens the doors for scientists to wonder what organism is out there—or could be created—to accomplish the task.

It has recently been argued that a self-consistency condition involving the Jarzynski equality (JE) and the Crooks fluctuation theorem (CFT) is violated for a simple Brownian process [L. Y. Chen, J. Chem. Phys.129, 091101 (2008)]. This note adopts the definitions in the...

Tiny marine isopods called gribbles were for centuries the bane of sailors, whose vessels were quickly devoured. Even today, piers and docks are rapidly gnawed away, and researchers have now been attracted to the enzymes in their gut, which can convert wood into sugars without the help of microbes.

It’s been a busy time for seismologists, but massive earthquakes also provides work for experts in civil engineering, urban planning, architecture, geography, and social support. The Earthquake Engineering Research Institute had just published its team report of the magnitude 7.0 quake in Haiti when the Chilean city of Concepción was moved 10 feet to the west by the most recent 8.8 magnitude earthquake.

What if space held the key to producing alternative energy crops on Earth? That's what researchers are hoping to find in a new experiment on the International Space Station. The experiment, National Lab Pathfinder-Cells 3, is aimed at learning whether microgravity can help jatropha curcas plant cells grow faster to produce biofuel, or renewable fuel derived from biological matter.
