Final NASA Eagleworks Paper Confirms Promising EM Drive Results (hacked.com)
An anonymous reader quotes a report from Hacked: Earlier this month Hacked reported that a draft version of the much expected EmDrive paper by the NASA Eagleworks team, had been leaked. Now, the final version of the paper has been published. The NASA Eagleworks paper, titled "Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum," has been published online as an open access "article in advance" in the American Institute of Aeronautics and Astronautics (AIAA)'s Journal of Propulsion and Power, a prestigious peer-reviewed journal. The paper will appear in the December print issue of the journal. The final version of the paper is very similar to the leaked draft. In particular, the NASA scientists confirm the promising experimental results: "Thrust data from forward, reverse, and null suggested that the system was consistently performing at 1.2 +/- 0.1 mNkW, which was very close to the average impulsive performance measured in air. A number of error sources were considered and discussed." The scientists add that, though the test campaign was not focused on optimizing performance and was more an exercise in existence proof, it is still useful to put the observed thrust-to-power figure of 1.2 mN/kW in context. "[For] missions with very large delta-v requirements, having a propellant consumption rate of zero could offset the higher power requirements. The 1.2 mN/kW performance parameter is over two orders of magnitude higher than other forms of 'zero propellant' propulsion, such as light sails, laser propulsion, and photon rockets having thrust-to-power levels in the 3.33--6.67 uN/kW (or 0.0033--0.0067 mN/kW) range." In other words, a modest thrust without having to carry fuel can be better, especially for long-distance space missions, than a higher thrust at the cost of having to carry bulky and heavy propellant reserves, and the EmDrive performs much better than the other "zero propellant" propulsion systems studied to date. -
German Scientists Confirm NASA's Controversial EM Drive
MarkWhittington writes: Hacked Magazine reported that a group of German scientists believe that they have confirmed that the EM Drive, the propulsion device that uses microwaves rather than rocket fuel, provides thrust. The experimental results are being presented at the American Institute for Aeronautics and Astronautics' Propulsion and Energy Forum in Orlando by Martin Tajmar, a professor and chair for Space Systems at the Dresden University of Technology. Tajmar has an interest in exotic propulsion methods, including one concept using "negative matter." -
Georgia Institute of Technology Researchers Bridge the Airgap
An anonymous reader writes Hacked has a piece about Georgia Institute of Technology researchers keylogging from a distance using the electromagnetic radiation of CPUs. They can reportedly do this from up to 6 meters away. In this video, using two Ubuntu laptops, they demonstrate that keystrokes are easily interpreted with the software they have developed. In their white paper they talk about the need for more research in this area so that hardware and software manufacturers will be able to develop more secure devices. For now, Faraday cages don't seem as crazy as they used to, or do they? -
Ancient Viruses Altered Human Brains
giulioprisco writes: A new study from Lund University in Sweden (abstract) indicates inherited viruses that are millions of years old play an important role in building up the complex networks that characterize the human brain. The Lund study shows that retroviruses seem to play a central role in the basic functions of the brain — over the course of evolution, the viruses took an increasingly firm hold on the steering wheel in our cellular machinery. In particular, the retroviruses seem to play an important role in the regulation of which genes are to be expressed, and when." -
Gun Rights Hacktivists To Fab 3D-Printed Guns At State Capitol
giulioprisco writes On January 13th Come And Take Texas (CATI) will be manufacturing 3D-printed firearms on location at the State Capitol. In 2013 Defense Distributed made public the 3D printable files (STL files) for the world's first fully 3D printable gun. Their more recent Ghost Gunner is designed to automatically manufacture publicly created designs with nearly zero user interaction. According to CATI’s website, “In the last year and a half Texan Gun Rights Groups all around the Lone Star State have walked, assembled, and engaged in Humanitarian efforts all while Open Carrying their Long Guns and Black Powder Pistols. This has succeeded in Educating the Public as well as Law Enforcement, to show that the presence of Firearms in Public is not only Safe but Highly supported.” -
Startup Acquisitions Herald Virtual, Augmented Reality Apps From Facebook
giulioprisco writes Oculus VR, the Virtual Reality (VR) technology company acquired by Facebook earlier this year, announced recently that they are acquiring two small start-up companies, Nimble VR and 13th Lab, to fill gaps in their virtual reality capabilities. The acquisitions may indicate that, besides VR games and social worlds, Facebook may target Augmented Reality (AR) applications, like Google is doing with Google Glass. -
Startup Magic Leap Hires Sci-Fi Writer Neal Stephenson As Chief Futurist
First time accepted submitter giulioprisco writes Magic Leap, a secretive Florida augmented reality startup that raised $542 million in October, hired renowned science fiction writer Neal Stephenson as its "Chief Futurist." Stephenson offers hints at the company's technology and philosophy: "Magic Leap is bringing physics, biology, code, and design together to build a system that is going to blow doors open for people who create things." According to the Magic Leap website, their Dynamic Digitized Lightfield Signal technology permits generating images indistinguishable from real objects.
