Submission + - Quantum Teleportation Sends Information 143 Kilometers (sciencedaily.com)

SchrodingerZ writes: "Scientists from around the world have collaborated to achieve quantum teleportation over 143 kilometers in free space . Quantum information was sent between the Canary Islands of La Palma and Tenerife. Quantum teleportation is not how it is made out in Star Trek though. Instead of sending an object (in this case a photon) from one location to another; the information of its quantum state is sent, making a photon on the other end look identical to the original .'Teleportation across 143 kilometres is a crucial milestone in this research, since that is roughly the minimum distance between the ground and orbiting satellites.' It is the hope of the research team that this experiment will lead to commercial use of quantum teleportation to interact with satellites and ground stations. This will increase the efficiency of satellite communication and help with the expansion of quantum internet usage. The full paper on the experiment can be found in the journal Nature here."

Firefox 4.0 Beta 1 Released 190

balster neb writes "Mozilla has released the first Beta of Firefox 4, the next major version of the popular web browser. Apart from the new 'Chromified' tabs-on-top UI, there are many major improvements in performance and HTML5 support. This release also adds support for the new WebM video format. Other changes include faster DOM and CSS performance, improved UI responsiveness, hardware 2D acceleration, experimental WebGL support, and better JavaScript performance (though this beta does not include the new JaegerMonkey JIT engine). More details on the Mozilla blog."

Not always. Sometimes you need to do something that looks really ass-backwards, and that may take a bit of commenting.
Yes indeed that's true. Sometimes you have to use hacks etc because of external libraries etc which can't modified. Then comments are good. In those cases we always start our comments with 'WHY:' or 'HACK:' to clearly indicate the reason for the comment.
