Dead Plants Hold Earthquake SecretsWith a few tricks borrowed from the oil industry, scientists are hoping to one day better understand why earthquakes start and stop. An easier alternative is to study faults exposed on Earth's surface, and look at "fossilized" earthquakes preserved along the faults. "That was the gold standard," said Heather Savage, a geophysicist at Lamont-Doherty Earth Observatory in New York. Just as rubbing your hands warms them on a winter's day, earthquakes heat the Earth when two sides of a fault slide past each other during a quake.)

Source of Galapagos Volcanism Not Where Scientists ThoughtThe volcanic plume that gave birth to the Galapagos Islands is not where scientists thought it was, a new study finds. Three-dimensional seismic images suggest the plume lies southeast of the chain's Fernandina Island, the spot where computer models place it. What's more, the plume is not being bent eastward by the migrating Nazca tectonic plate (atop which the Galapagos Islands sit), but appears to be moving northward. "Having the plume relocated helped explain why [many of] the Galapagos volcanoes are active," said Douglas Toomey, a geologist at the University of Oregon and leader of the study, detailed online Jan. 19 in the journal Nature Geoscience.

NASA's Humanoid Robonaut 2 Waltz Both Elegant and Creepy (Video)NASA's robot butler for astronauts, Robonaut 2, may still be waiting for its legs to be delivered to the International Space Station, but you can see how the humanoid automaton may dance in weightlessness with an eerie elegance in this new video.  The video waltz of NASA's Robonaut 2, set to the "The Blue Danube" by Johann Strauss, was created by SPACE.com by stitches together a series of NASA recordings of the droid's prehensile leg tests. The $2.5 million Robonaut 2, also called R2, is designed to eventually work with the astronauts and even take over some of their duties both inside and outside the space station. An R2 unit launched to the orbiting outpost as just a torso with arms and camera-equipped head during the last flight of the space shuttle Discovery in 2011.

China Moon Rover Hits Snag in Big Lunar Science MissionChina's Jade Rabbit moon rover may have stubbed its lucky foot. The state-run Xinhua news agency reported Saturday that China's Yutu moon rover(the name means Jade Rabbit) "has experienced a mechanical control abnormality, and scientists are organizing repairs." It is not clear how serious the abnormality, but the news agency said the moon rover's malfunction occurred due to the "complicated lunar surface environment," citing the State Administration of Science, Technology and Industry for National Defense (SASTIND).

Using marijuana during pregnancy could affect a baby's brain development by interfering with how brain cells are wired, a new study in mice and human tissue suggests. Researchers studied marijuana's effects on mice and brain tissue from human fetuses, and found that the active ingredient in marijuana, THC, interferes with the formation of connections between nerve cells in the cerebral cortex, the part of the brain responsible for higher thinking skills and forming memories. "Our advice is that [pregnant] mothers should avoid marijuana,"said neuroscientist Tibor Harkany of the Karolinska Institute in Sweden, and the Medical University of Vienna, in Austria, who led a study detailed today (Jan. 27) in the EMBO Journal.

Dark Matter Mystery Could Be Solved in Next 10 YearsDark matter — the mysterious stuff that is thought to make up most of the matter in the known universe — may reveal itself during the next decade, one prominent scientist predicts. When the moment comes, it will result in "a pivotal paradigm shift in physics," Gianfranco Bertone, a physicist with the University of Amsterdam in the Netherlands, said in a talk on dark matter research at a Royal Society Frontiers of Astronomy conference in London in November. The elusive substance may show itself as researchers set out to test "the existence of some of the most promising dark matter candidates, with a wide array of experiments, including the Large Hadron Collider (LHC) at CERN and a new generation of astroparticle experiments underground and in space," Bertone said. So far, the only evidence of dark matter's existence comes from the gravitational effects it exerts on visible matter.

'Super Ball Bot' Could Explore Saturn's Huge Moon TitanIt was a baby’s toy, of all things, that sparked a new spacecraft design concept to explore the murky surface of Saturn's largest moon. Adrian Agogino and Vytas Sunspiral, who both work in the Intelligent Systems Division at NASA Ames Research Center, were batting around a "tensegrity" in the office a few years ago.

7,000-Year-Old Human Bones Suggest New Date for Light-Skin GeneAn ancient European hunter-gatherer man had dark skin and blue eyes, a new genetic analysis has revealed. The analysis of the man, who lived in modern-day Spain only about 7,000 years ago, shows light-skin genes in Europeans evolved much more recently than previously thought. The findings, which were detailed today (Jan. 26) in the journal Nature, also hint that light skin evolved not to adjust to the lower-light conditions in Europe compared with Africa, but instead to the new diet that emerged after the agricultural revolution, said study co-author Carles Lalueza-Fox, a paleogenomics researcher at Pompeu Fabra University in Spain. The hunter-gatherer's dark skin pushes this date forward to only 7,000 years ago, suggesting that at least some humans lived considerably longer than thought in Europe before losing the dark pigmentation that evolved under Africa's sun.

Grand Canyon's Age? A Mix As Wild As the WestThe Colorado River took the easy route when it carved the Grand Canyon through Arizona's ruddy sandstones and pastel limestones, a new study claims. "I think the Colorado River found low places and paleocanyons and ancient topographies that led to the Grand Canyon," said Karl Karlstrom, lead study author and a geologist at the University of New Mexico in Albuquerque. But the study may do little to resolve the heated debate over the age of the Grand Canyon. For the past year, Karlstrom and others have stridently attacked work published Nov. 29, 2012, in the journal Science that suggested the westernmost Grand Canyon was 70 million years old.

Cosmic Lens Caught Bending Bright Gamma-Ray Burst, a Space FirstA telescope in space has captured a rare kind of cosmic allignment for the first time. NASA's Fermi telescope has captured the first gamma-ray measurements of a gravitational lens, a rare natural alignment in which a massive body distorts light from a more distant object. A team of international astronomers used the observatory to study the emission from one galaxy as its energetic emissions passed through another spiral galaxy on their way toward Earth. Fermi itself could even serve to identify more of these rare natural telescopes.
