NASA's rovers continue Martian missions
NASA's Mars rover Opportunity is trying to escape from a sand trap, while its twin, Spirit, has been busy finding new clues to a wet and violent early Martian history. Rover-team scientists described the robot explorers' activities today at the spring meetings of the American Geophysical Union in New Orleans.

Voyager spacecraft enters solar system's final frontier
NASA's Voyager 1 spacecraft has entered the solar system's final frontier. It is entering a vast, turbulent expanse, where the sun's influence ends and the solar wind crashes into the thin gas between stars.

Very large diamonds produced very fast
Researchers at the Carnegie Institution's Geophysical Laboratory have learned to produce 10-carat, half-inch thick single-crystal diamonds at rapid growth rates (100 micrometers per hour) using a chemical vapor deposition (CVD) process. This size is approximately five times that of commercially available diamonds produced by the standard high-pressure/high-temperature (HPHT) method and other CVD techniques. In addition, the team has made colorless single-crystal diamonds, transparent from the ultraviolet to infrared wavelengths with their CVD process.

Global wind map may provide better locations for wind farms
A new global wind power map has quantified global wind power and may help planners place turbines in locations that can maximize power from the winds and provide widely available low-cost energy. After analyzing more than 8,000 wind speed measurements in an effort to identify the world's wind power potential for the first time, researchers suggest that wind captured at specific locations, if even partially harnessed, can generate more than enough power to satisfy the world's energy demands.

Little microbe inside sea squirt makes big splash
Sea squirts around the world are breathing a sigh of relief, as they no longer run the risk of being harvested for their natural disease-fighting substances. Scientists recently discovered that the bacterium Prochloron didemnii, which lives symbiotically inside the sea squirt, actually produces the desired patellamides, compounds that may one day be used in cancer treatment.

Deep thoughts of a birdbrain
Recording from the forebrain of pigeons performing a working memory task, the authors of a study published in the open-access journal PLoS Biology find sustained neural activity during the memory period.

Killer dinosaurs turned vegetarian
Scientists have discovered a mass graveyard of bird-like feathered dinosaurs in Utah. The previously unknown species provides clues about how vicious meat-eaters related to Velociraptor ultimately evolved into plant-munching vegetarians.

Clutch hitters and choke hitters: Myth or reality?
Sports announcers already know it, and now Elan Fuld has proven it: clutch hitters really do exist.
The 21-year-old University of Pennsylvania junior studied the phenomenon of clutch hitting in baseball, and his calculations provided statistical evidence that players such as Eddie Murray, Frank Duffy and Luis Gomez were clutch hitters.
Fuld studied playing statistics of 1,075 Major League players in the 1974-1992 seasons.

A mission to conquer Venus
There is new hope that NASA may be able to repeat their success of Mars rovers Opportunity and Spirit on Venus. Space scientists in the US say that an autonomous solar-powered aircraft could take measurements of Venus's wild atmosphere, while flying a "brain" to control a toughened rover on the ground.

Discovery of an American salamander where it shouldn't be: Korea
The most prevalent salamander worldwide is the lungless or terrestrial salamander, which is found only in the Americas with a lone outpost in Italy. Now an Illinois-born high school teacher has found one in Korea under the noses of herpetologists well versed in the aquatic salamanders of the peninsula. The find, says UC Berkeley's David Wake, who described the new genus, implies a once worldwide distribution that has shrunk over the past 100 million years.
