  1. Banjo Used In Brain Surgery

    Science · · posted by kdawson · from the not-that-way-silly dept. · 164 comments
    Ponca City, We love you writes "Legendary bluegrass musician Eddie Adcock has undergone brain surgery to treat a hand tremor, playing his banjo throughout to test the success of the procedure. Adcock suffers from essential tremor, a condition where there is a continuing deterioration in areas of the brain that control movement, causing a tremor that usually appears when the person tries to act or move. Deep brain stimulation can be used to treat the movement difficulties of both Parkinson's and essential tremor by sinking an electrode into the thalamus, a deep brain area that is part of the motor loop — a circuit that helps coordinate movement. Surgeons placed electrodes in Adcock's brain and fitted a pacemaker in his chest, which delivers a small current that shuts down the region of his brain causing the tremors. The most sensible thing to do was to tweak the system while Adcock was playing the banjo to optimize the effect for the thing that's most important to him."

  2. Slashback: Passports, Microscopes, IQ Points

    Slashback tonight with updates and clarifications on recent Slashdot stories (and story arcs), including a downright Operatic end to Jon S. von Tetzchner's cross-oceanic attempt (or was that just in fun?), the status of post-death email privacy, minimizing the dangers of RFID passports, and more - read on for the details.

    Actually, it's taking tests that reduces IQ. The guys at Mind Hacks have dissected the widely reported story that 'email destroys the mind faster than marijuana' [Posted on Slashdot a few days ago -- T.] and found that it is more spin than science. The results show simply that people do worse at IQ tests when distracted, although Hewlett-Packard are not releasing details of the experiment, so others cannot even evaluate if the research is sound. The use of psychobabble for marketing marches on.

    One day this will all be commemorated as ... an opera. GreyPoopon writes "It looks like Jon's attempt at swimming the Atlantic has ended in early failure. Taking the blame once again is is PR Manager, Eskil Sivertsen. The raft he was using was somehow punctured this morning, and Jon had to abondon his trek to perform a heroic rescue. Perhaps someone should take on the task of sending our downtrodden adventurer a cup of Mom's hot chocolate."

    PCP theorem simplified, still way over my head. Stridar writes "Sanjeev Arora's proof of the PCP theorem was a great acheivement. This theorem, a reduction of NP to PCP, allowed for many striking results on the difficulty of finding approximate solutions to NP-Hard problems. However, his original proof is long and technical, focusing on the arithmetization of booelan formulas. It has long been an open problem to simplify this result. Now Irit Dinur , a mathematician at the Hebrew University, has given a purely combinatorial proof of the PCP theorem, in her exciting paper "The PCP Theorem by Gap Amplification" ."

    I think several other things end at death, too. microbee writes "The Register reports that Yahoo has complied with a court order to give a dead soldier's email account to his parents. It's not clear to me from the news whether they got direct access to the actual mail box, or just hard copy of those emails. If the former, it's a bit funny to read "the family complain they have only got emails received by Justin, not those he wrote." People have to wonder whether their privacy ends at death."

    Haven't they ever seen The Killing Fields? valdean writes "Following up on past Slashdot stories, Wired News reports that the State Department is now considering adding a password to the new RFID passports, in response to 'criticism from computer security professionals and civil libertarians.' According to the article, 'The data... would be locked and unavailable to any reader that doesn't know a secret key or password to unlock the data. To obtain the key, a passport officer would need to physically scan the machine-readable text that's printed on the passport page beneath the photo... The reader would then hash the data to create a unique key that could be used to authenticate the reader and unlock the data on the RFID chip.'"

    Anything with LEDs in it makes me happy. HunterD writes "Apparently a company called DigitalBlue purchased the rights to the Intel Play series, which included the Intel QX3 microscope. Well, DigitalBlue has released an upgrade called the QX5 that features an Ultrabright LED, a better camera, and a number of other upgrades."
