writes with news about a project that hopes to create an open source code platform for drones. "The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux and collaborative development, today announced the founding of the Dronecode Project. The Project will bring together existing open source drone projects and assets under a nonprofit structure governed by The Linux Foundation. The result will be a common, shared open source platform for Unmanned Aerial Vehicles (UAVs). Founding members include 3D Robotics, Baidu, Box, DroneDeploy, Intel, jDrones, Laser Navigation, Qualcomm, SkyWard, Squadrone System, Walkera and Yuneec. Dronecode includes the APM UAV software platform and associated code, which until now has been hosted by 3D Robotics, a world leader in advanced UAV autopilot and autonomous vehicle control. The company was co-founded by Chris Anderson, formerly editor-in-chief of Wired"Read Replies (0)

writes The E-Cat (or "Energy Catalyzer") is an alleged cold fusion device that produces heat from a low-energy nuclear reaction where nickel and hydrogen fuse into copper. Previous reports have tended to suggest the technology is a hoax, and the inventor Andrea Rossi's reluctance to share details of the device haven't helped the situation. ExtremeTech now reports that "six (reputable) researchers from Italy and Sweden" have "observed a small E-Cat over 32 days, where it produced net energy of 1.5 megawatt-hours, "far more than can be obtained from any known chemical sources in the small reactor volume."... "The researchers, analyzing the fuel before and after the 32-day burn, note that there is an isotope shift from a "natural" mix of Nickel-58/Nickel-60 to almost entirely Nickel-62 — a reaction that, the researchers say, cannot occur without nuclear reactions (i.e. fusion)." The paper (PDF) linked in the article concludes that the E-cat is "a device giving heat energy compatible with nuclear transformations, but it operates at low energy and gives neither nuclear radioactive waste nor emits radiation. From basic general knowledge in nuclear physics this should not be possible. Nevertheless we have to relate to the fact that the experimental results from our test show heat production beyond chemical burning, and that the E-Cat fuel undergoes nuclear transformations. It is certainly most unsatisfying that these results so far have no convincing theoretical explanation, but the experimental results cannot be dismissed or ignored just because of lack of theoretical understanding. Moreover, the E-Cat results are too conspicuous not to be followed up in detail. In addition, if proven sustainable in further tests the E-Cat invention has a large potential to become an important energy source."
The observers understandably hedge a bit, though: The researchers are very careful about not actually saying that cold fusion/LENR is the source of the E-Cat’s energy, instead merely saying that an “unknown reaction” is at work. In serious scientific circles, LENR is still a bit of a joke/taboo topic. The paper is actually somewhat comical in this regard: The researchers really try to work out how the E-Cat produces so much darn energy — and they conclude that fusion is the only answer — but then they reel it all back in by adding: “The reaction speculation above should only be considered as an example of reasoning and not a serious conjecture.”Read Replies (0)

Two and a half years ago, we posted news of the completion
of the Star Wars Uncut project
. Now, reader kdataman
writes that another fan-made Star Wars
movie remake is ready to watch; this time it's Empire
: 480 fan-created 15-second clips have been assembled to remake the entire movie, scene for scene (but not always word for word). The variations swing from professional production values to cardboard cutouts, but they are all creative and many are hilarious. Hard to pick a favorite scene but the guys at MTV selected a few highlights.Read Replies (0)

Thomas Eric Duncan, the first person to have been diagnosed in the U.S. with Ebola, and who subsequently died of the disease, was treated at Texas Health Presbyterian Hospital in Dallas. Now, in a second diagnosis for the U.S
, an unidentified health-care worker from the hospital has tested positive for Ebola as well. According to the linked Reuters story, Texas officials did not identify the worker or give any details about the person, but CNN said it was a woman nurse.
The worker was wearing full protective gear when in contact with Duncan, Texas Health Resources chief clinical officer Dan Varga told a news conference.
"We are very concerned," Varga said. "We don't have a full analysis of all of the care. We are going through that right now."
The worker was self-monitoring and has not worked during the last two days, Varga said.
The worker was taking their own temperature twice a day and, as a result of the monitoring, the worker informed the hospital of a fever and was isolated immediately upon their arrival, the hospital said in a statement.
(Also covered by the Associated Press, as carried by the Boston Globe
, which notes that "If the preliminary diagnosis is confirmed, it would be the first known case of the disease being contracted or transmitted in the U.S.")Read Replies (0)
