Fuel Free Spacecrafts Using Graphene 265

Posted by samzenpus from the to-the-stars-and-beyond dept.
William Robinson writes: While using a laser to cut a sponge made of crumpled sheets of Graphene oxide, researchers accidentally discovered that it can turn light into motion. As the laser cut into the material, it mysteriously propelled forward. Baffled, researchers investigated further. The Graphene material was put in a vacuum and again shot with a laser. Incredibly, the laser still pushed the sponge forward, and by as much as 40 centimeters. Researchers even got the Graphene to move by focusing ordinary sunlight on it with a lens. Though scientists are not sure why this happens, they are excited with new possibilities such as light propelled spacecraft that does not need fuel.

That is risky. From a security POV, SDN is an absolute nightmare. And while that has been clear to actual security experts for a long time, it seems to get harder to ignore for management in the recent past. My point is that we could actually see a regression back to "one cable, one logical network link", because other things are unable to give you a perimeter or any kind of zone-separation.

Of course, SDN could turn out to be secure and even NSA-proof, but who really believes that?

If you earn 210K, but cannot afford to be unemployed for more then 3 months, than the problem is on your side because you are spending too much money. I would even say that it is unlikely that you will get this salary again if you switch jobs, as your current salary is way above even most high-qualification jobs.

Live Anthrax Shipped Accidentally To S Korea and US Labs 67

Posted by samzenpus from the bad-package dept.
New submitter hamsterz1 writes: U.S. Officials say that the military mistakenly sent live anthrax to laboratories in nine states and an air base in South Korea, after apparently failing to properly inactivate the bacteria. Four lab workers in the United States and up to 22 overseas have been given precautionary medical treatment. The CDC is investigating the incident and Pentagon spokesman Colonel Steve Warren says, "Out of an abundance of caution, [the Defence Department] has stopped the shipment of this material from its labs pending completion of the investigation."

How a Scientist Fooled Millions With Bizarre Chocolate Diet Claims 260

Posted by timothy from the tongue-in-cheek-sandwich-diet-works-too dept.
__roo writes: Did you know chocolate helps you lose weight? You can read all about this great news for chocoholics in the Daily Star, Daily Express, Irish Examiner, and TV shows in Texas and Australia, and even the front page of Bild, Europe's largest daily newspaper. The problem is that it's not true. A researcher who previously worked with Science to do a sting operation on fee-charging open access journals ran a real—but obviously flawed—study rigged to generate false positives, paid €600 to get it published in a fee-charging open access journal, set up a website for a fake institute, and issued press releases to feed the ever-hungry pool of nutrition journalists. The doctor who ran the trial had the idea to use chocolate, because it's a favorite of the "whole food" fanatics. "Bitter chocolate tastes bad, therefore it must be good for you. It's like a religion."

The response recommends that the Federal Circuit ruling stand, allowing Oracle to retain copyright to the Java API.

Ways To Travel Faster Than Light Without Violating Relativity 226

Posted by samzenpus from the greased-lightning dept.
StartsWithABang writes: It's one of the cardinal laws of physics and the underlying principle of Einstein's relativity itself: the fact that there's a universal speed limit to the motion of anything through space and time, the speed of light, or c. Light itself will always move at this speed (as well as certain other phenomena, like the force of gravity), while anything with mass — like all known particles of matter and antimatter — will always move slower than that. But if you want something to travel faster-than-light, you aren't, as you might think, relegated to the realm of science fiction. There are real, physical phenomena that do exactly this, and yet are perfectly consistent with relativity.
