Al writes "A company called PolyPlus has developed lithium metal-air batteries that have 10 times the energy density of regular lithium-ion batteries. The anode is made up entirely of lithium metal, and the surrounding air acts as the cathode, making the batteries incredibly energy dense. Previous efforts to make lithium metal batteries have been stymied by the sensitivity of lithium to water in the air. The new batteries use a sophisticated membrane to protect the lithium anode and PolyPlus has even created a version that works underwater, by drawing oxygen through the membrane. Lithium metal-air batteries could be light-weight power sources for demand for plug-in hybrid vehicles and consumer electronics; IBM also recently announced that it would develop lithium metal-air batteries for the energy grid and for transportation."

Defeat Globalism writes to tell us that many journalists, bloggers, and media law specialists are concerned about a new ruling by a US Court of Appeals in Boston. The new ruling is allowing a former Staples employee to sue the company for libel after an email was sent out informing other employees that he had been fired for violations of company procedures regarding expense reimbursements. "Staples has asked the full appeals court to reconsider the ruling, and 51 news organizations have filed a friend-of-the-court brief saying that the decision, if allowed to stand, 'will create a precedent that hinders the media's ability to rely on truthful publication to avoid defamation liability.' But Wendy Sibbison, the Greenfield appellate lawyer for the fired Staples employee, Alan S. Noonan, said the ruling applies only to lawsuits by private figures against private defendants, that is, defendants not involved in the news business, over purely private matters."

An anonymous reader writes "Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, in Japan, have discovered a spin battery effect: the ability to store energy into the magnetic spin of a material and to later extract that energy as electricity, without a chemical reaction. The researchers have built an actual device to demonstrate the effect that has a diameter about that of a human hair. This is a potentially game-changing discovery that could affect battery and other technologies. Quoting: Although the actual device... cannot even light up an LED..., the energy that might be stored in this way could potentially run a car for miles. The possibilities are endless, Barnes said.'"
TRNick writes "Is the future of gaming more or less free, perhaps funded by advertising or micropayments? A bunch of MMOs have pioneered the way, and now they are being followed by the likes of EA, Sony and id Software, each of which is offering some form of free gaming. But it's not just the big guys. TechRadar talks to a new generation of indie developers who are making names for themselves. 'I make most of my money from sponsors,' says one. 'We're all here because we love making games first and foremost,' says another. But can free games ever make enough money to fund the really ambitious, event games that get the headlines?"
While paid games aren't likely to be on their way out any time soon, more and more developers and publishers are experimenting with cheaper pricing, and the results so far seem positive.
