Though some would have you believe that games are nothing but a breeding ground for murderers, one of the current console contenders is hoping that some of the industry's up-and-comers can convince us that games can change the world. In association with Games for Change - a movement that strives to use games as a means for social change - Microsoft is hosting a competition called the "Xbox 360 Games for Change Challenge" that will seek out new talent for the purposes of creating a game based on the current socio-political climate of the world today.
Scientists now say that an ocean several miles deep once covered a third of the surface of the planet, enough water to support the origin and evolution of life. The red planet, they said, had once been a deep blue, just like Earth.
Since 1991, planetary scientists have floated the idea that Mars once harbored vast oceans that covered roughly one-third of the planet. Two long shore-like lips of rock in the planet's northern hemisphere were thought to be the best evidence, but experts argued that they were too "hilly" to describe the smooth edges of ancient oceans.
The view just changed dramatically with a surprisingly simple breakthrough.

It can take a village to save science -- a village that so far includes a Las Vegas music mogul, Kirkland rocket scientist, Port Townsend artist, Bothell chemist, Louisiana gas-and-oil man with a place in Port Angeles and a Savannah, Ga., computer programmer.
Russian computers controlling the International Space Station's (ISS) orientation and supply of oxygen and water have failed, Nasa officials say.
Biologists at the University of California, Riverside have identified the genes, and determined the DNA sequences, for two key proteins in the "dragline silk" of the black widow spider - an advance that may lead to a variety of new materials for industrial, medical and military uses.
A massive international study of the human genome has caused scientists to rethink some of the most basic concepts of cellular function. Genes, it turns out, may be relatively minor players in genetic processes that are far more subtle and complicated than previously imagined.
Among the critical findings: A huge amount of DNA long regarded as useless -- and dismissively labeled "junk DNA" -- now appears to be essential to the regulatory processes that control cells. Also, the regions of DNA lying between genes may be powerful triggers for diseases -- and may hold the key for potential cures.
The research, published in a set of papers in today's editions of the journals Nature and Genome Research, raised far more questions than it answered -- and in a sense was a rallying cry for more and deeper research into the functioning of the genome, often referred to as the "blueprint" for life.

Eastman Kodak Co. (NYSE:EK - news) said on Thursday it has developed digital camera technology that nearly eliminates the need for flash photography, part of the company's effort to make money from its deep patent portfolio.
The world's biggest maker of photographic film says its proprietary sensor technology significantly increases sensitivity to light. Image sensors act as a digital camera's eyes by converting light into an electric charge to begin the capture process.
Kodak, which is in the last year of a lengthy and expensive transformation into a digital photography company as its film business shrinks, intends to lean on its wealth of intellectual property to boost its bottom line, expecting up to $250 million this year alone in royalties and related revenues.
For example, Chief Executive Antonio Perez has previously said its new inkjet printer strategy grew out of the discovery of existing, unused patents for printer ink.
"Our strategy is to get it out of the lab and onto the street," said Chris McNiffe, general manager, Kodak Image Sensor Solutions.

An international team of astronomers with the Trans-atlantic Exoplanet Survey today announce the discovery of their third planet, TrES-3. The new planet was identified by astronomers looking for transiting planets - that is, planets that pass in front of their home star - using a network of small automated telescopes in Arizona, California, and the Canary Islands. TrES-3 was discovered in the constellation Hercules about 10 degrees west of Vega, the brightest star in the summer skies.
"TrES-3 is an unusual planet as it orbits its parent star in just 31 hours!," said Georgi Mandushev, Lowell Observatory astronomer. "That is to say, the year on this planet lasts less than one and a third days. It is also a very massive planet - about twice the mass of the solar system's biggest planet, Jupiter - and is one of the planets with the shortest known periods."

The international space station's newest power source, a set of solar wings, made its debut yesterday.
The solar array is part of a new 17.5-ton space station segment that was connected to the orbiting outpost during a spacewalk Monday.
The solar wings were deployed one at a time, first halfway unfurled and allowed to warm in the sun about 30 minutes. That prevented the solar panels from sticking together.
"We see a good deploy," astronaut James Reilly, who helped connect the new segment on Monday, said after the second wing was unfurled.
