The Grown-Up Video Game 152

Posted by Soulskill from the getajob-hero dept.
Phaethon360 writes "Now, more than ever, we're seeing many Mature ratings (M+, 17+, 18) being distributed by various national media regulators. But that isn't the only indicator for a game's intended audience. It doesn't take a thousand swear words, scantily clad women or gratuitous violence to differentiate a ten-year-old's game from a twenty-year-old's. The spectrum of human emotions encompasses a wider palette than just revenge, fear, and loss, but the games that shy away from these are frequently mistaken as being for a younger audience. From the article: 'The human experience is one that is made up of great hardship, pain, loss, death, and a multitude of experiences seemingly designed to destroy a person. However, that same experience is also filled with joy, love, laughter, family and friends. ... These so-called “grown-up” games need not be relegated to the category of niche gaming. In fact, at times we find that these video games are capable of reaching mass popularity among the gaming community. It is here that we find one of our generation’s outlets for the expression of conflict.'"

Creating Electric Power From Light Using Gold Nanoparticles 77

Posted by Soulskill from the nanite-power-supply dept.
cyberfringe writes "Professor of Materials Science Dawn Bonnell and colleagues at the University of Pennsylvania have discovered a way to turn optical radiation into electrical current that could lead to self-powering molecular circuits and efficient data storage. They create surface plasmons that ride the surface of gold nanoparticles on a glass substrate. Surface plasmons were found to increase the efficiency of current production by a factor of four to 20, and with many independent parameters to optimize, enhancement factors could reach into the thousands. 'If the efficiency of the system could be scaled up without any additional, unforeseen limitations, we could conceivably manufacture a 1A, 1V sample the diameter of a human hair and an inch long,' Prof. Bonnell explained. The academic paper was published in the current issue of ACS Nano. (Abstract available for free.) The significance? This may allow the creation of nano-sized circuits that can power themselves through sunlight (or another directed light source). Delivery of power to nanodevices is one of the big challenges in the field."
