Neutrinos traveling faster than light according to CERN measurements

Ok, the big news is this: Researchers have gotten results that would indicate, if true, that something could travel faster than the speed of light. This is not supposed to be possible according to Einsteins theory of relativity because nothing should be able to travel faster than light in vacuum.

However, researchers have now measurements (15 thousand of them) that says that neutrinos (sub-atomic particles) travelled at a velocity 20 parts per million above the speed of light. They now invite other researchers to try and find out why these measurements turned out as they did. Was there some kind of systematic error, or do we need to redo much of what we understand about physics.

here is the press release from CERN about neutrinos traveling faster than the speed of light.
And a lot of people have already managed to post news about this news.
here is gizmag and XKCD two nerdy sites that i follow.


Spider leg moving by itself after it got detached from the body

My wife had me come and look at a spider leg that kept moving by itself after she had picked it up and the leg got loose from the spider’s body.

I do wonder what would cause the leg to continue moving this long after it had been severed from the spiders body. I have no idea. Could the impulses frmo the spider somehow travel through the moist surface of the sing? Nah, that doesn’t sound plausible. Hmm… I am not sure how the mechanics of spider legs work.
