Commercial silicon-based solar cells - such as those seen on the roofs of houses across the country - operate at about 20% efficiency for converting the Sun's rays into electrical energy. It's taken over 20 years to achieve that rate of efficiency.
New research finds that online social behavior isn’t replacing offline social behavior in the gaming community. Instead, online gaming is expanding players’ social lives. The study was done by researchers at North Carolina State University, York University and the University of Ontario Institute of Technology.
Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color or polarization, selectivity based on the direction of propagation has remained elusive.
A state-of-the-art ‘Mars yard’ is now ready to put the ExoMars rover through its paces before the vehicle is launched to the Red Planet in 2018.
How do you grow a supermassive black hole that is a million to a billion times the mass of our sun? Astronomers do not know the answer, but a new study using data from NASA's Wide-field Infrared Survey Explorer, or WISE, has turned up what might be the cosmic seeds from which a black hole will sprout. The results are helping scientists piece together the evolution of supermassive black holes -- powerful objects that dominate the hearts of all galaxies.

While carbon dioxide is typically painted as the bad boy of greenhouse gases, methane is roughly 30 times more potent as a heat-trapping gas.
This is going to be one hell of a summer for geeks, especially considering we’ve got Transformers: Age of Extinction, and Godzilla coming up. In fact, Mark Wahlberg is so excited to be part of Transformers, he’s already proclaimed it will be “the biggest movie of 2014.”
Mike Judge, the creator of Beavis and Butthead, Office Space, and King of the Hill, is back with a goof on Silicon Valley, which is called, you guessed it, Silicon Valley. You may have seen the ads for it already, and it has the cast wearing black turtle necks, doing their best Steve Jobs poses.
No Hellboy doesn’t need any time off for a vacation, but he was given a day that celebrated the beloved graphic novel character’s twentieth anniversary, and Mike Mignola, who created Hellboy, couldn’t have been more thrilled.
These days, fans expect a sequel to a film to be at least as good as the first installment, forget about better than the original. And it looks like the latest Captain America film is at least as good, if not better, than the first.
The debate about the destructive qualities of games should continue for a long time. Many times when a national tragedy occurs, video games and violent movies are often blamed, and now a study claims that gaming can encourage racism.
There have been rumors and speculation about a sequel to Pacific Rim for quite some time, but the question has always been did the movie make enough money that a sequel would be a good investment? While reviews were mixed, the fans definitely liked the film, and maybe the cult of Pacific Rim would grow big enough that by the time a sequel would be ready, a whole new audience would possibly be waiting for it as well.
Most of you are probably like me, getting really annoyed when you buy a new car and discover it has a media system that is years behind current technology.

Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy. Now researchers from Barcelona and Athens suggest that both possibilities are only a mirage in the observations and it is the quantum vacuum which could be behind this energy that moves our universe.

Recently Funny or Die did a joke campaign about the Back to the Future hoverboard, and some actually believed this could be a reality. While it was a nicely executed joke, there is a new special that explores the possibilities of a real hoverboard, as well as the technology of Star Wars.
While the reviews for Divergent have been pretty lackluster, there’s little doubt it’s going to be a big hit at the box office. In fact, one major ticket buying site reports that 80% of advance sales are for Divergent’s opening weekend, with 93% of fans wanting to see it opening weekend.
So after many years of net rumors and speculations, Ghostbusters 3 is finally a go, and it’s being slated for a 2015 start. Yet after the passing of Harold Ramis, who played Egon Spengler, Ivan Reitman is stepping down from the director’s chair, because his heart just isn’t in it without Harold.
While it’s often hard to tell how the gaming market can do, we at TGD think this could be a strong year for games, even with the market’s often abrupt transition periods. And there may be more change in the air as gaming shifts from physical consoles to streaming.
While there’s no official word just yet, David Fincher, director of Fight Club and The Social Network, is up to helm the official Steve Jobs biopic, which will be released by Sony. Aaron Sorkin wrote the screenplay, and now reports are burning up the net as to who could play the title role.

Black and gray markets for computer hacking tools, services and byproducts such as stolen credit card numbers continue to expand, creating an increasing threat to businesses, governments and individuals, according to a new RAND Corporation study.
Plants convert energy from sunlight into chemical energy during a process called photosynthesis. This energy is passed on to humans and animals that eat the plants, and thus photosynthesis is the primary source of energy for all life on Earth.
Lick Observatory's newest telescope, the Automated Planet Finder (APF), has been operating robotically night after night on Mt. Hamilton since January, searching nearby stars for Earth-sized planets.
A research team in Spain has the enviable job of testing out new electromechanical gear for potential use in future missions to the "Red Planet." They do it within their Mars environmental simulation chamber, which is specially designed to mimic conditions on the fourth planet from the sun -- right down to its infamous Martian dust.
As with many things in nature, it helps to understand the past when trying to predict the future. Ilya Bindeman, an associate professor of geological sciences at the University of Oregon, believes this is true of the Yellowstone supervolcano and the likelihood that it will produce an apocalyptic eruption as it has three times over the last the last 2 million years.
Children who repeatedly play violent video games are learning thought patterns that will stick with them and influence behaviors as they grow older, according to a new study by Iowa State University researchers. The effect is the same regardless of age, gender or culture. Douglas Gentile, an associate professor of psychology and lead author of the study published in JAMA Pediatrics, says it is really no different than learning math or to play the piano.
The growing and justified concern about the current global warming process has kindled the interest of the scientific community in geological records as an archive of crucial information to understand the physical and ecological effects of ancient climate changes.
The Rufus Cuff boasts a 3-inch display and is fully capable of running Android apps from the Google Store.
Computer chips have stopped getting faster: The regular performance improvements we’ve come to expect are now the result of chipmakers’ adding more cores, or processing units, to their chips, rather than increasing their clock speed.
Inspired by natural materials such as bone — a matrix of minerals and other substances, including living cells — MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots.
Recently physicists have been poking holes again in Stephen Hawking’s black hole theory – including Hawking himself. For decades physicists across the globe have been trying to figure out the mysteries of black holes – those fascinating monstrous entities that have such intense gravitational pull that nothing – not even light – can escape from them. Now Professor Chris Adami, Michigan State University, has jumped into the fray.
