Astronomers Discover 17-Year Interference Caused by Microwave Oven
For nearly 17 years astronomers at Parkes Observatory in Australia searched for the reason why radio interference took place during experiments and observations. They discovered early this year that the interference was coming from a microwave oven in the observatory’s kitchen. Parkes Observatory houses one of the best-known radio telescopes in the country. It is used to … [Read more...]
Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking
Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]
FBI Pulled Security Expert from Flight for Alleged Hacking Concerns
The FBI pulled Chris Roberts, a computer security expert, from his United Airlines Flight last Wednesday in Syracuse because of suspicions that he hacked the airplane. Roberts tweeted referencing the plane’s communication systems suggesting he was going to use his laptop to force the plane’s emergency oxygen masks to deploy. The tweet read: “Find Myself on a 737/800, let’s see … [Read more...]
