Sense of Smell Tied To Quantum Physics? 169

SpaceAdmiral writes "A controversial theory that proposes that our sense of smell is based not on the shape of the molecules that enter our nose but on their vibrations was given a boost recently when University College London researchers determined that the quantum physics involved makes sense. The theory, proposed in the mid-1990s by biophysicist Luca Turin, suggests that electron tunneling initiates the smell signal being sent to the brain. It could explain why similarly shaped molecules can have very different smells, and molecules with very different structures can smell similar." Turin has now formed a company to design odorants using his theory, and claims an advantage over the competition of two orders of magnitude in rate of discovery. The article concludes, "At the very least, he is putting his money where his nose is."

Kent State's Facebook Ban for Athletes 248

Most commenting readers scoffed at Kent State University's new policy (noted on Slashdot yesterday) forbidding athletes from using profiles on Facebook. The arguments offered (legal, moral, and practical) mostly berated the school for limiting their students to no good end, but some thought-provoking comments exposed at least some complexities which make the issue less clear-cut than a straightforward case either of censorship or contractual freedom. Read on for a sampling of the comments which typified the conversation.

Senate Passes Patriot Act Renewal 705

IAmTheDave writes "The Senate has passed a renewal of the Patriot act, 89-10, after two extensions caused by months of negotiations. The only thing standing in the way of a full renewal is a House vote, expected to pass next week. The renewal comes with some privacy protections attached, however, some worry they are only cosmetic. Some lawmakers who voted for the package acknowledged deep reservations about the power it would grant to any president. "Our support for the Patriot Act does not mean a blank check for the president," said Democratic leader Harry Reid of Nevada, who voted to pass the bill package. Certain lawmakers supported passing the bill even though they were still wary about it - Arlen Specter urged his colleagues to pass it even as he promised to introduce a new measure and hold hearings on how to fix it. Terrorism aside, the bill also includes new legislation that has almost nothing to do with terrorism, like one measure, which would make it harder for illicit labs to obtain ingredients for methamphetamine by requiring pharmacies to sell nonprescription cold medicines only from behind the counter. I know that people like Arlen Specter promise further hearings - but why pass what you know is flawed?"
