Reducing the need for diesel generators improves security and decreases the need for supply convoys.A U.S. Marine regiment in Afghanistan has used solar panels to reduce the amount of diesel it uses in generators from 20 gallons a day to just 2.5 gallons, according to a news report from the Marines."Our generators typically use more than 20 gallons of fuel a day. We are down to 2.5 gallons a day," said [Staff Sergeant David] Doty, 3rd Squad Leader, with 1st Platoon, 'I' Company, and Fulton, Mo., native. "The system works amazing. By saving fuel for generators, it has cut back on the number of convoys, meaning less opportunity for one of our vehicles to hit an IED."The panels are used to recharge batteries for laptops, radios, and lighting. They're part of a program called the Experimental Forward Operating Base (ExFOB).According to Staff Sgt. Greg Wenzel, 1st Plt., platoon sergeant, this has helped PB Sparks' security when the sun goes down. [Read the full article]
Conventional entanglement cuts across this world, quite literally. It acts along the the x-axis, linking particles instantly in time and in defiance of the boundaries to these wedges.What Olson and Ralph show is that entanglement can just as easily work along the y-axis too. In other words, entanglement is so deeply enmeshed in the universe that a measurement in the past has an automatic influence on the future.That may sound like a truism. Isn't this is how the universe works, I hear you say. But this isn't ordinary cause and effect; there are some interesting subtleties to this phenomenon.To see how, imagine an experiment that Ralph and Olson describe in which a qubit is sent into the future. The idea is that a detector acts on a qubit and then generates a classical message describing how this particle can be detected. [Read the full article]
"We are now making a user's address and mobile phone number accessible as part of the User Graph object."That's how Facebook's blog for developers announced that from now on the apps you install to your Facebook profile will be able to access to your phone number and home address. It's a feature some predict will be misused by spammers. Editor of the site allfacebook.com, Jackie Cohen, said:"You can imagine, for instance, that bad guys could set up a rogue app that collects mobile phone numbers and then uses that information for the purposes of SMS spamming or sells on the data to cold-calling companies."I think something to highlight as well is that users can not simply allow some things to be shared and some not. Instead they are only able to click allow everything or nothing. I think if they added different levels or tiers of sharing and showed Facebook users which the application was requesting, it would improve the whole situation. [Read the full article]
