We've heard researchers tout the many benefits of graphene before, and it doesn't look like they're showing any signs of letting up, with a group from the University of Manchester now boasting that they've made even more progress with the material that was created only a few years ago. Specifically, they've apparently found a way to develop graphene-based films (an alternative to the current indium-based options) more cheaply by simply "dissolving" chunks of graphite into graphene and then "spraying the suspension onto a glass surface." What's more, the researchers say that there are only a "few small, incremental steps" remaining before the graphene film is ready for the mass production stage, after which they say we could be seeing graphene-based LCD products within "a few years." As you may recall, this all follows some similar developments from researchers at the Max Planck Institute in Germany, although their method apparently "involved several extra steps," and they weren't making any promises about actual products turning up anytime soon.

We've already seen a few viruses delivered via hardware, but a group of researchers from University of Illinois at Urbana-Champaign are now warning that we may not have seen anything yet. As New Scientist reports, they've apparently managed to develop their own "malicious circuits," which they say can interfere with a computer at a deeper level than a virus, and completely bypass traditional anti-virus software. To accomplish that slightly unsettling feat, the researchers created a replica of the open source Leon3 processor, and added about 1,000 malicious circuits not present in the original processor. Once they hooked that up to another computer they were apparently not only able to swipe passwords from memory, but install malware that would allow the operating system to be remotely controlled as well. Of course, they admit that sneaking such malicious circuits onto a chip isn't exactly an easy proposition, given that someone would either need to have access to a chip during its manufacturing process, or have the ability to manufacture their own. Or, as the project's lead researcher puts it, it's "not something someone would carry out on weekends."
