OnGreen to Develop Large Cleantech Mentor-Student Network Los Angeles, CA (PRWEB) October 03, 2011 The California Institute of Technology (Caltech) and their Resnick Institute, in partnership with UC Los Angeles (UCLA), University of Southern California (USC), and OnGreen, announced today they received a $360,000 grant from the U.S. Department of Energy (DOE) to accelerate cleantech innovation by fostering student entrepreneurship through a Western Regional business plan competition. This...

Astronomers have caught sight of an unusual galaxy that has illuminated new details about a celestial "sandbar" connecting two massive islands of galaxies. The research was conducted in part with NASA's Spitzer Space Telescope. These "sandbars," or filaments, are known to span vast distances between galaxy clusters and form a lattice-like structure known as the cosmic web. Though immense, these filaments are difficult to see and study in detail. Two years ago, Spitzer's infrared eyes revealed...

Biologists from the California Institute of Technology (Caltech) and Yale University have identified two genes, the leucokinin neuropeptide and the leucokinin receptor, that appear to regulate meal sizes and frequency in fruit flies. Both genes have mammalian counterparts that seem to play a similar role in food intake, indicating that the steps that control meal size and meal frequency are not just behaviorally similar but are controlled by the same genes throughout the animal kingdom. A...

Brain images during money-transfer experiments show "rich" participants prefer to see others get financial windfall The human brain is a big believer in equality"”and a team of scientists from the California Institute of Technology (Caltech) and Trinity College in Dublin, Ireland, has become the first to gather the images to prove it. Specifically, the team found that the reward centers in the human brain respond more strongly when a poor person receives a financial reward than when a...

But not the last, now that astronomers know where to look An extraordinarily bright, extraordinarily long-lasting supernova named SN 2007bi, snagged in a search by a robotic telescope, turns out to be the first example of the kind of stars that first populated the Universe. The superbright supernova occurred in a nearby dwarf galaxy, a kind of galaxy that's common but has been little studied until now, and the unusual supernova could be the first of many such events soon to be discovered. SN...

A team of scientists from the California Institute of Technology (Caltech) have pinpointed two groups of neurons in fruit fly brains that have the ability to sense and manipulate the fly's fat stores in much the same way as do neurons in the mammalian brain. The existence of this sort of control over fat deposition and metabolic rates makes the flies a potentially useful model for the study of human obesity, the researchers note.Their findings were published in the August 13 issue of the...

Engineers from NASA's Jet Propulsion Laboratory and students at the California Institute of Technology have designed and tested a versatile, low-mass robot that can rappel off cliffs, travel nimbly over steep and rocky terrain, and explore deep craters. This prototype rover, called Axel, might help future robotic spacecraft better explore and investigate foreign worlds such as Mars. On Earth, Axel might assist in search-and-rescue operations. "Axel extends our ability to explore terrains that...

Although some might see low-tech voting in the hi-tech United States, experts say Americans will find more reliable and secure voting systems in this election than in 2000 and 2004. "We have retired the punch card ballots, which were demonstrably a bad way to vote," said Charles Stewart, head of political science at the Massachusetts Institute of Technology and member of the Caltech/MIT Voting Technology Project. Many voters can recall the ballot problems that occurred in Florida during the...

A cosmic explosion seen last February may have been the "tip of an iceberg," showing that powerful, distant gamma ray bursts are outnumbered ten-to-one by less-energetic cousins, according to an international team of astronomers. A study of the explosion with X-ray and radio telescopes showed that it is "100 times less energetic than gamma ray bursts seen in the distant universe. We were able to see it because it's relatively nearby," said Alicia Soderberg, of Caltech, leader of the research...
