Scientists Turn Used LCDs Into Medicine 30

schliz writes "Scientists from the University of York have come up with a new recycling technique that extracts PVA from used LCD panels to create a 'a bioactive sponge.' The technique could allow recovered PVA to be used in pills, wound dressings and tissue scaffolds that aid human tissue regeneration. It could also keep waste LCD screens from incineration or landfill altogether."

Unusual Physics Engine Game Ported To Linux 117

christian.einfeldt writes "Halloween has come early for Linux-loving gamers in the form of the scary Penumbra game trilogy, which has just recently been ported natively to GNU-Linux by the manufacturer, Frictional Games. The Penumbra games, named Overture, Black Plague and Requiem, are first-person survival horror and physics puzzle games which challenge the player to survive in a mine in Greenland which has been taken over by a monstrous infection/demon/cthulhu-esque thing. The graphics, sounds, and plot are all admirable in a scary sort of way. The protagonist is an ordinary human with no particular powers at all, who fumbles around in the dark mine fighting zombified dogs or fleeing from infected humans. But the game is remarkable for its physics engine — rather than just bump and acquire, the player must use the mouse to physically turn knobs and open doors; and the player can grab and throw pretty much anything in the environment. The physics engine drives objects to fly and fall exactly as one would expect. The porting of a game with such a deft physics engine natively to Linux might be one of the most noteworthy events for GNU-Linux gamers since the World of Goo Linux port."

Harvard Study Says Weak Copyright Benefits Society 326

An anonymous reader writes "Michael Geist summarizes an important new study on file sharing from economists Felix Oberholzer-Gee and Koleman Strumpf. The Harvard Business School working paper finds that given the increase in artistic production along with the greater public access conclude that 'weaker copyright protection, it seems, has benefited society.' The authors point out that file sharing may not result in reduced incentives to create if the willingness to pay for 'complements' such as concerts or author speaking tours increases."

Submission + - Buckyballs Polymerised into Buckywires ( 1

KentuckyFC writes: "Scientists have found a way to join buckyballs together so that they form buckywires. The wires form when buckyballs are dissolved in an aromatic hydrocarbon called 1,2,4-trimethylbenzene. The 1,2,4-trimethylbenzene links the balls together to make buckywires shaped like a string of pearls, which then precipatate out. This relatively simple procedure opens the door to industrial scale manufacture. Buckywires ought to be efficient light harvesters because of their great surface area and the way they can conduct photon-liberated electrons. But perhaps the area of greatest interest is drug delivery. The researchers suggest that buckywires ought to be safer than carbon nanotubes because the production method is entirely metal-free. That cannot be said of nanotubes because the reaction that forms them is catalysed by metallic nanoparticles."

Comment With GTK+ & Cairo you can do anything these da (Score 1) 948

I don't understand this. There's a reasonably clear HIG document in GNOME which is continuously updated. The strict packing rules make the resulting interface flexible in regards to RTL languages and reasonably consistent with other applications. GTK+ has widgets for just about every purpose. Since the introduction of Cairo it is trivial to draw custom widgets, especially using the gtkmm and cairomm C++ bindings: the custom tab bar could be done in a day. With those bindings it is even quite easy to modify the behaviour of existing widgets by overloading their signal handlers, Murray Cumming and the others working on those have invested a great deal of effort to truly (and easily) expose the object system via C++.

Wikipedia Launches a New Mobile Interface, Seeks Help 70

hampton2600 writes "The Wikimedia Foundation is proud to present our new mobile site optimized for modern high-end phones. The interface is focused on being clean and easy to read on your mobile device. We currently officially support reading on the iPhone and Android phones. The new gateway is written entirely in Ruby (using the Merb framework) and the Git repository can be found here. We are looking for open source help with supporting other phone types and translations into new languages. Currently 8 languages are supported, but we'd like to support all languages Wikipedia supports. This is an active project and we are looking for new features, etc. from the community."

Comment Re:Fix the intel graphics bugs yet? (Score 2, Interesting) 620

I agree with you that this issue seems to have been thoroughly ignored by the release engineers, who pushed the 2.6 driver through despite its downfalls. (apparently to gain support for some newer chipsets, which could've been simply backported by adding PCI ID's to the 2.4 driver)

Compositing and 3D performance are horrid and even non-composited 2D is slow when EXA is used. Apparently, if you're lucky you can switch to UXA, but it is non-functional on my systems. (G35: no modes found & i915: DRI disabled)

The issue can be improved (but not fixed) by using a backport of the version 2.4 intel driver available from the "" PPA of siretart. This provides minor performance enhancements but is still slower than intrepid.

Does Professional Gaming Have a Future? 116

mr_sifter writes "Three years ago, celebrity gamers such as Fatal1ty were bagging millions in prizes, and TV channels were queuing up to broadcast games on TV. Professional gaming looked set for the big time. It never happened, and in the current economic crisis, sponsors and media organizations are cutting costs, resulting in the closure of many pro gaming competitions (as we recently discussed) and a down-scaling in prize money. This feature looks at whether pro gaming can bounce back, and whether it will always be a PC sport, or if pro gaming on consoles is the future."
