writes with news of the Chinese military's latest toy, an ICBM capable of delivering multiple warheads across the Pacific. From the article: The DF-41 is designed to have a range of 12,000 kilometers (7,500 miles), according to a report by Jane's Strategic Weapon Systems, putting it among the world's longest-range missiles/ ... It is "possibly capable of carrying multiple independently targetable re-entry vehicles", the U.S. Defense Department said in a report in June, referring to a payload of several nuclear warheads. It also quoted a Chinese military analyst as saying: "As the U.S. continues to strengthen its missile defense system, developing third generation nuclear weapons capable of carrying multiple warheads is the trend." China's previous longest range missile was the DF-5A, which can carry a single warhead as far as 12,000 km, according to Jane's.Read Replies (0)

writes with news that NASA scientists have tested the EmDrive
, which claims to use quantum vacuum plasma
for propulsion. Theoretically improbable, but perhaps possible after all. If it does work, it would eliminate the need for expendable fuel (just add electricity). From the article:Either the results are completely wrong, or NASA has confirmed a major breakthrough in space propulsion. A working microwave thruster would radically cut the cost of satellites and space stations and extend their working life, drive deep-space missions, and take astronauts to Mars in weeks rather than months. ... [According to the researchers] "Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma."
Skepticism is certainly warranted: NASA researchers were only able to produce about 1/1000th of the force the Chinese researchers reported. But they were careful to avoid false sensor readings, so something
is going on. The paper declined to comment on what that could be, leaving the physics of the system an open problem.Read Replies (0)

You remember Peter Hoddie, right? He was one of the original QuickTime
developers at Apple. He left in 2002 to help found a startup called Kinoma
, which started life developing multimedia players and browsers for mobile devices. Kinoma was acquired in 2011 by Marvell Semiconductor
, whose management kept it as a separate entity.
, and they're not the only ones to notice this product. Quite a few developers and companies are jumping on the 'Internet of Things' bandwagon, so there may be a decent -- and growing -- market for something like this. (Alternate Video Link
