  BBC News | Sci/Tech | Biological computer born 

  http://news.bbc.co.uk/1/hi/sci/tech/358822.stm

  Wednesday, June 2, 1999 Published at 13:12 GMT 14:12 UK Sci/Tech Biological computer born Living computer: interconnected leech neurons can add up A computer made of neurons taken from leeches has been ... created by US scientists. At the moment, the device can perform simple sums - the team calls the novel calculator the "leech-ulator". But their aim is to devise a new generation of fast and flexible computers that can work out for themselves how to solve a problem, rather than having to be told exactly what to do. Professor Bill Ditto, at the Georgia Institute of Technology, is leading the project and says he is amazed that today's computers are still so dumb. "Ordinary computers need absolutely correct information every time to come to the right answer," he says. "We hope a biological computer will come to the correct answer based on partial information, by filling in the gaps itself." Well connected The device the team has built can "think for itself" because the leech neurons are able   [More...] [Less...]

  Scienceline » Bringing Bioimaging Back

  Steve Isaacman is building things in the lab—floppy, tennis-ball-looking things. They are considered by some to be the future of bioimaging, a field where tiny compounds are sent into the bloodstream, ... allowing physicians to “see” a specific malady. One of the ways researchers can see into the body is with magnetic resonance imaging, or MRI, a visualization tool used to home in on a blood clot, identify a broken bone, or spot cancer—the disease Isaacman is most interested in. But as it stands, current methods for visualizing ailments within the body have much to be desired, says James Canary, head of the chemistry lab where Isaacman is stirring three flasks full of what looks like pomegranate juice. Canary says “targeted contrast agents” that will distinguish between different maladies within the body – such as different types of cancer – and do so at a finer level are needed to improve this area of medicine. Contrast agents help distinguish a healthy area of the body from a broken one.   [More...] [Less...]

  Welcome to The Institution of Engineering and Technology BioSysBio Event 2008! News 24.10.07 - Call for Abstracts issued About the Conference IET BioSysBio 2008 is primarily aimed at graduate students, ... post-docs and junior faculty working in biology and biotechnology. Following the very successful BioSysBio 2007 event held in Manchester, The IET BioSysBio 2008 will again bring together the best young researchers working in Synthetic Biology, Systems Biology and Bioinformatics, providing a platform to hear and discuss the most recent scientific advances and applications in these fascinating fields. The IET BioSysBio 2008 will also provide a focus on researcher training, with a series of hands on workshops integrated into the main programme. It is the organiser’s intention to provide a unique platform for graduate students and junior faculty to present to their peers via a series of short 10-20 minute presentations. Sessions will be chaired by leading experts who will also discuss their   [More...] [Less...]
