Drones appear to be seriously vulnerable to hackers seeking to commandeer the vehicles by ‘spoofing,’ or faking, GPS satellite navigation signals. An overview of a federal study, obtained by the Monitor, discusses the problem and remedies.
Researchers are enhancing a dense network of GPS receivers with temperature, air-pressure, and motion sensors common in today's smart phones. The prototype promises precious minutes of advance warning for extreme weather, tsunamis, and earthquakes.
State courts and legislatures are grappling with the murky legal principles governing police surveillance and privacy. One point of concern: GPS-enabled smart phones can now reveal razor-sharp details about a person’s movements.
Last year CERN researchers clocked neutrinos moving faster than light, in an apparent violation of the laws of physics. Now it seems that it was actually a bad measurement caused by a loose fiber optic cable.
Experiments conducted in Europe in September and November appeared to show neutrinos violating Einstein's theory of special relativity. But now scientists suspect it could be a faulty measurement caused by bad connection.
