Submission + - Quantum physics and reality part ways

aeoneal writes: Quantum physics says goodbye to reality , PhysicsWeb has announced. Researchers at the University of Vienna have fulfilled John Bell's prediction of violating Bell's inequality. From the article: "[Studies] have ruled out all hidden-variables theories based on joint assumptions of realism, meaning that reality exists when we are not observing it; and locality, meaning that separated events cannot influence one another instantaneously. But a violation of Bell's inequality does not tell specifically which assumption — realism, locality or both—is discordant with quantum mechanics."

The real question, of course, is whether Slashdot is actually here when we're not online. Does a server count as an observer?

Submission + - World's first tricorder created by Purdue

aeoneal writes: According to Science Daily, mass spectrometry is no longer limited to what can be taken to the lab. Purdue researchers have created a handy 20 lb. device that combines mass spectrometry with DESI (desorption electrospray ionization), allowing chemical composition to be determined outside of a vacuum chamber. Purdue suggests this could be useful for everything from detecting explosive substances or cancer to predicting disease. Researcher R. Graham Cooks says, "We like to compare it to the tricorder because it is truly a hand-held instrument that yields information about the precise chemical composition of samples in a matter of minutes without harming the samples."
