“The rover discovered evidence for low temperature liquid water and environments that would be conducive for life,” said Scott M. McLennan, Professor of Geochemistry at Stony Brook University and a member of the team that published the paper (Steven Squyres of Cornell University headed the team and is the principal investigator for the science instruments carried by the rover). Dr. McLennan noted that this was the third area on Mars visited by the Mars rovers that has produced evidence of “habitable” ancient geological environments.
Opportunity was one of two exploration rovers that landed on Mars eight years ago for what was planned as a three-month mission. According to the NASA Jet Propulsion Laboratory, Opportunity reached Endeavour Crater last August after driving for three years from another Martian crater, Victoria.
Dr. McLennan said Opportunity found highly elevated levels of zinc in some of the rocks at the rim of the crater, suggesting that there was a hydrothermal system – warm water – running through the rocks at one time. In addition, veins of gypsum discovered at the crater were strong evidence that low temperature waters had at one time passed through those rocks.
“If we found this on Earth there would be no question that you could find evidence of life,” said Dr. McLennan, noting that the Rover sent back some “spectacular” photos of the gypsum veins.
The Mars Rover Opportunity has given Stony Brook faculty and graduate and undergraduate students the opportunity to collaborate for eight years on scientific study of Mars as part of the Stony Brook Mars rover group, Dr. McLennan said. While Opportunity and its sister Rover Spirit were scheduled to operate for three months, “Everyone felt they had the capability of lasting quite a bit longer, but nobody thought Opportunity would last this long.” NASA selected Dr. McLennan to participate in the Mars Exploration Rover (MER) Mission.
The mission consisted of two rovers that arrived on opposite sides of Mars in 2004. Dr. McLennan has investigated data on Martian rock and surface deposits to gain insight into the ancient climates of that planet and contribute to NASA's overarching strategy of Mars Exploration: "Follow the Water", the search for past life on Mars, understanding past climates and why the climate changed so drastically, and evaluating the planet for human exploration. Opportunity landed in Eagle Crater on Mars on Jan. 25, 2004, three weeks after its rover twin, Spirit, landed halfway around the planet. Spirit stopped communicating in March 2010.
Powered by solar panels, Opportunity went into “hibernation” on a sun facing slope at the crater’s rim during the Martian winter due to reduced sunlight. It is scheduled to come out of that hibernation by mid-2012 or earlier if wind cleans dust off its solar panels. According to NASA, researchers plan to drive Opportunity in search of clay minerals that a Mars orbiter's observations indicate lie on Endeavour's rim.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
