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."
