Sound As the New Illegal Narcotic? 561

ehrichweiss writes "The Oklahoma Bureau of Narcotics is warning parents and teachers of a new threat to our children: sounds. Apparently kids are now discovering binaural beats and using them to get 'physiological effects.' The report goes on with everyone suggesting that such aural experiences will act as a gateway to drug usage and even has one student claiming there are 'demons' involved. Anyone who has used one of those light/sound machines knows all about the effects that these sounds will give and to state that they will lead kids to do drugs is nonsense at best. It seems the trend in scaring the citizens with a made-up problem has gone to the next level."

+ - Wrinkles in nanoscale-sized films

Submitted by

Roland Piquepaille writes "An international team of scientists from Chile, the Netherlands and the U.S. has found a very simple way to measure the material properties of thin films having a thickness of only a dozen nanometers. The researchers just dropped water on thin film floating in a Petri dish. This causes wrinkles to appear on the ultrathin polymer films they've tested. And they found that the number and length of the wrinkles are determined by the elasticity and thickness of the film. In other words, they've found an easy way to discover the mechanical properties of films which might be used for applications such as cosmetics, coatings, and nanoelectronics.

+ - Birth, life and death of a photon

Submitted by
Roland Piquepaille
Roland Piquepaille writes "Two days ago, I told you that German physicists had built a single-photon server (read more on Slashdot or on ZDNet). But French researchers also have used ultra cold atoms of rubidium to record the full life of a photon. This was one of Einstein's dreams, but it was thought as an impossible one before. In fact, a photon disappears when it delivers its information. But with what has been described as an 'experimental masterwork,' the physicists have observed the 'quantum jumps' done by single photons for as long as half a second. This discovery should lead to important developments for future high performance computers and quantum computing — and certainly to the field of physics. Read more for additional references and a picture of how the team recorded the full life of a photon — not present in the short AFP article"
