Submission + - RINGS propels satellites without propellants (gizmag.com)

cylonlover writes: Astronauts on the International Space Station (ISS) are testing a new propulsion system ... inside the station. While this might seem like the height of recklessness, this particular system doesn't use rockets or propellants. Developed in the University of Maryland's Space Power and Propulsion Laboratory, this new electromagnetic propulsion technology called the Resonant Inductive Near-field Generation System (RINGS) uses magnetic fields to move spacecraft as a way to increase service life and make satellite formation flying more practical.

Submission + - NASA abandons Kepler repairs, looks to the future (gizmag.com)

cylonlover writes: If NASA has anything to say about it, Kepler is down, but not out. At a press teleconference on Thursday it announced that it has abandoned efforts to repair the damaged unmanned probe, which was designed to search for extrasolar planets and is no longer steady enough to continue its hunt. But the space agency is looking into alternative missions for the spacecraft based on its remaining capabilities.

Submission + - Bioengineered mouse heart gets a beat using human cells (gizmag.com)

cylonlover writes: Heart transplants have given new life to thousands, but are only an unfulfilled hope to thousands more due to a shortage of donor organs. With the goal of meeting this shortfall, scientists at the University of Pittsburgh School of Medicine have bioengineered a mouse heart in the lab that beats on its own. The mouse heart had its cells replaced with human cells, offering the potential of growing custom replacement hearts that wouldn't be rejected by the recipient.

Submission + - Radical new icebreaker will travel through the ice sideways (gizmag.com) 1

cylonlover writes: Given that icebreakers clear a path for other ships by traveling through the ice head-on (or sometimes butt-on), then in order for one of them to clear a wider path, it would have to be wider and thus larger overall ... right? Well, Finland’s Arctech Helsinki Shipyard is taking a different, more efficient approach. It’s in the process of building an asymmetric-hulled icebreaker that can increase its frontal area, by making its way through the ice at an angle of up to 30 degrees.

Submission + - NASA and ESA to communicate with lunar orbiter using lasers (gizmag.com)

cylonlover writes: Space communications have relied on radio since the first Sputnik in 1957. It’s a mature, reliable technology, but it’s reaching its limits. The amount of data sent has increased exponentially for decades and NASA expects the trend to continue. The current communications systems are reaching their limits, so NASA and ESA are going beyond radio as a solution. As part of this effort, ESA has finished tests of part of a new communications system, in preparations for a demonstration in October in which it will receive a laser data download from a NASA lunar orbiter.

Submission + - Full-size remote control cars – coming soon to a road near you? (gizmag.com)

cylonlover writes: Thanks to efforts of groups such as Google, Oxford University, BMW and Continental, we’re getting closer and closer to the advent of autonomous cars – vehicles that drive themselves, with the human “driver” pretty much just along as a passenger. Researchers at Germany’s Technische Universität München (TUM), however, are looking at taking things a step further. They’re developing remote-control cars that could travel along city streets with no one in them at all, their operator located somewhere far away.

Submission + - Slingatron to hurl payloads into orbit (gizmag.com)

cylonlover writes: People have been shooting things into space since the 1940s, but in every case this has involved using rockets. This works, but it’s incredibly expensive with the cheapest launch costs hovering around US$2,000 per pound. This is in part because almost every bit of the rocket is either destroyed or rendered unusable once it has put the payload into orbit. Reusable launch vehicles like the SpaceX Grasshopper offer one way to bring costs down, but another approach is to dump the rockets altogether and hurl payloads into orbit. That's what HyperV Technologies Corp. of Chantilly, Virginia is hoping to achieve with a “mechanical hypervelocity mass accelerator” called the slingatron.

Submission + - The physics of the world's fastest man (gizmag.com)

cylonlover writes: The Honourable Usain Bolt (Order of Jamaica; Commander of the Order of Distinction) is often held out as the world's fastest man. The reigning Olympic champion in the 100-meter and 200-meter sprints as well as a member of the Olympic champion 4x100 meter relay team, Bolt is the first man to win six Olympic gold medals in sprinting, and is a five-time world champion. Long and lanky at 6 ft 5 in (2 m) tall, he towers above the (mostly) much shorter sprinters. How has he managed to come out on top for the past five years? A team of physicists from the Universidad Nacional Autonoma de Mexico (UNAM) has analyzed Bolt's past performances in the 100-meter sprint to understand what makes a record-breaker.

Submission + - HAARP ionospheric research program set to continue (gizmag.com)

cylonlover writes: Reports that the High Frequency Active Auroral Research Program (HAARP) had been shut down permanently were apparently a bit premature. According to HAARP program manager James Keeney, the facility is only temporarily off the air while operating contractors are changed. So why does anyone care? Despite being associated with various natural disasters over the past two decades by the conspiracy fringe, HAARP is in reality a facility for studying the ionosphere. Gizmag takes a look at the goings on at HAARP – past, present, and future.

Submission + - Self-assembling multi-copter demonstrates networked flight control (gizmag.com)

cylonlover writes: Researchers at ETH Zurich have demonstrated an amazing capability for small robots to self-assemble and take to the air as a multi-rotor helicopter. Maximilian Kriegleder and Raymond Oung worked with Professor Raffaello D’Andrea at his research lab to develop the small hexagonal pods that assemble into flying rafts. The true accomplishment of this research is that there is not one robot in control – each unit in itself decides what actions to take to keep the group in the air in what's known as Distributed Flight Array.

Submission + - James Bond's creator, and the real spy gadgets he inspired (gizmag.com)

cylonlover writes: It's one of the most memorable moments in perhaps the best James Bond film, From Russia with Love: SPECTRE agent Rosa Klebb, posing as a hotel maid, drops her gun, and appears to be at a disadvantage as she goes toe to toe with Sean Connery's imposing Bond. That is until she deploys her iconic poison-tipped dagger shoes, which have gone on to be copied in other notable action films and Wild Wild West. But as kitsch as Klebb's cleaver clogs might seem, the CIA attempted to replicate them, and another classic Bond gadget, in real life, according to research by Dr. Christopher Moran of Warwick University. At the heart of the story is the close friendship of Bond author and Ian Fleming and former CIA Director Allen Dulles. Gizmag spoke to Moran about 20th century Intelligence, and its peculiar relationship with the fictional British spy.

Submission + - Chatbot hunts for pedophiles (gizmag.com)

cylonlover writes: For a number of years now, police forces around the world have enlisted officers to pose as kids in online chat rooms, in an attempt to draw out pedophiles and track them down. Researchers at Spain’s University of Deusto are now hoping to free those cops up for other duties, and to catch more offenders, via a chatbot that they’ve created. Its name is Negobot, and it plays the part of a 14 year-old girl.

Submission + - Wood nanobattery could be green option for large-scale energy storage (gizmag.com)

cylonlover writes: Li-ion batteries may be ok for your smartphone, but when it comes to large-scale energy storage, the priorities suddenly shift from compactness and cycling performance (at which Li-ion batteries excel) to low cost and environmental feasibility (in which Li-ion batteries still have much room for improvement). A new "wood battery" could allow the emerging sodium-ion battery technology to fit the bill as a long-lasting, efficient and environmentally friendly battery for large-scale energy storage.

Submission + - Telescopic contact lens with switchable magnification to help AMD patients (gizmag.com)

cylonlover writes: Age-related macular degeneration (AMD) is the leading cause of blindness among older adults in the western world. Unfortunately, conventional optical aids provide little help for a retina which has lost the acuity of its central area. Now a team of multinational researchers led by University of California, San Diego (UCSD) Professor Joseph Ford has created a telescopic contact lens that can switch between normal and magnified vision to offer AMD patients a relatively unobtrusive way to enhance their vision.

Submission + - Beyond military drones – the future of unmanned flight (gizmag.com)

cylonlover writes: In April of this year, a BAE Systems Jetstream research aircraft flew from Preston in Lancashire, England, to Inverness, Scotland and back. This 500-mile (805 km) journey wouldn't be worth noting if it weren't for the small detail that its pilot was not on board, but sitting on the ground in Warton, Lancashire and that the plane did most of the flying itself. Even this alteration of a standard commercial prop plane into an Unmanned Aerial Vehicle (UAV) seems a back page item until you realize that this may herald the biggest revolution in civil aviation since Wilbur Wright won the coin toss at Kitty Hawk in 1903.
