  1. Intelligent System Hunts Out Malware Hidden In Shortened URLs

    Tech · Security · · posted by timothy · from the click-here-for-the-rest dept. · 16 comments
    An anonymous reader writes: Computer scientists at a group of UK universities are developing a system to detect malicious code in shortened URLs on Twitter. The intelligent system will be stress-tested during the European Football Championships next summer, on the basis that attackers typically disguise links to malicious servers in a tweet about an exciting part of an event to take advantage of the hype.

  2. Programming Cells, With CellOS

    Developers · Biotech · · posted by timothy · from the undeclared-membrane-operations-are-fatal dept. · 58 comments
    First time accepted submitter JoeMerchant writes "An international team of synthetic biologists, led by professor of computer science Natalio Krasnogor at the University of Nottingham, hopes to revolutionize synthetic biology with what they call CellOS, a 'bottom-up approach to cellular computing, in which computational chemical processes are encapsulated within liposomes.' The bold project is aptly named AUdACiOuS."

  3. Human Ear Could Be Next Biometric System

    narramissic writes "A team of researchers at the University of Southampton, UK, has received funding from the UK's Engineering and Physical Sciences Research Council to learn whether otoacoustic emissions (OAE), the ear-generated sounds that emanate from within the spiral-shaped cochlea in the inner ear, can be used as a viable biometric technology like fingerprints and IRIS recognition. According to a report in New Scientist, someday instead of asking for passwords or pin numbers, a call center or bank would simply use a device on their telephone to produce a brief series of clicks in the recipient's ear to confirm the person is who they say they are." Try faking that with gummy bears.

  4. Portable Brain Scanner to Save Premature Babies

    Science · Science · · posted by ScuttleMonkey · from the monstir-in-my-pocket dept. · 93 comments
    Roland Piquepaille writes "Researchers at UCL (University College London) are developing a portable brain scanner which could help save the lives of premature and newborn babies in intensive care by avoiding to move them to conventional scanning facilities. A current prototype combines the advantages of both magnetic resonance imaging (MRI) and ultrasound. It uses optical tomography to generate images showing how the brain is working and a new generation should be ready by 2008 and such scanners should be commercially available shortly after."

  5. Xen High-Performance x86 Virtualization Released

    · posted by ryuzaki0 · from the cool-beans dept. · 316 comments
    Xen Team writes "The University of Cambridge Computer Laboratory Systems Research Group is pleased to announce the open source release of Xen, a virtual machine monitor for x86. Xen lets you run multiple operating system images at the same time on the same PC hardware, with unprecedented levels of performance and resource isolation. Even under the most demanding workloads the performance overhead is just a few percent --- considerably less than alternatives such as VMware Workstation and User Mode Linux. This makes Xen ideal for use in providing secure virtual hosting, or even just for running multiple OSes on a desktop machine."

    The Xen team continues: "Xen requires guest operating systems to be ported to run over it. Crucially, only the kernel needs to be ported, and all user-level application binaries and libraries can run unmodified. We have a fully functional port of Linux 2.4.22 running over Xen, and regularly use it for running demanding applications like Apache, PostgreSQL and Mozilla. Any Linux distribution should run unmodified over the ported kernel. With assistance from Microsoft Research, we have a port of Windows XP to Xen nearly complete, and are planning a FreeBSD 4.8 port in the near future.

    "Visit the project homepage to find out more, and download the project source code or the XenDemoCD, a bootable 'live iso' image that enables you to play with Xen/Linux 2.4 without needing to install it on your hard drive. The CD also contains full source code, build tools, and benchmarks. Our SOSP paper gives an overview of the design of Xen, and evaluates the performance against other virtualization techniques.

    "Work on Xen is supported by UK EPSRC grant GR/S01894, Intel Research Cambridge, and Microsoft Research Cambridge via an Embedded XP IFP award."
