The US military is developing Star Wars-style hoverbikes

Last time we heard from Malloy Aeronautics, it was testing hoverbike technology with a robot-carrying drone . A few months later, it’s partnering with a Maryland-based defense company to develop a hoverbike for the US military . Working with Survice Engineering Co., the UK aeronautics company will set up shop in Maryland as part of “an ongoing research and development contract.” The duo will also work with the US Army Research Laboratory on the project that aims to create “a new class of Tactical Reconnaissance Vehicle (TRV).” The goal is to replace some of the work a helicopter does with the hoverbikes, a vehicle that provides increased safety and costs significantly less. “With adducted rotors you immediately not only protect people and property if you were to bump into them, but if you ever were to bump into somebody or property it’s going to bring the aircraft out of the air, ” Malloy’s marketing sales director Grant Stapleton told Reuters . Funds from a Kickstarter campaign for those compact UAVs was used to build scale models capable of carrying a human — one of which was on display at the Paris Air Show.

UCLA discovers how solar cells’ charges can last for weeks

Solar cells have always been inspired by photosynthesis, so it’s only natural for researchers to take cues from different aspects of the energy-making process. A team of UCLA chemists, for instance, have developed a way that will allow solar cells to keep their charge for weeks instead of just a few seconds like current products are capable of. According to Sarah Tolbert, UCLA chem professor and one of the study’s authors , they looked into plants’ nanoscale structures that can keep negatively charged molecules separated from positively charged ones. “That separation is the key to making the process so efficient, ” she said. The team has discovered that in order to mimic those nanoscale structures in plastic solar cells (which are potentially cheaper to make than silicon-based ones), they need to use two components: a polymer donor and a nano-scale fullerene acceptor. The team describes the process as follows: The UCLA technology arranges the elements more neatly — like small bundles of uncooked spaghetti with precisely placed meatballs (see image below). Some fullerene meatballs are designed to sit inside the spaghetti bundles, but others are forced to stay on the outside. The fullerenes inside the structure take electrons from the polymers and toss them to the outside fullerene, which can effectively keep the electrons away from the polymer for weeks. In short, those two can form the right “noodle and meatball” structure to keep different charges away from each other for days to weeks, greatly improving a cell’s capability to retain power. It’s also a plus that the components can auto-assemble, simply by putting them in water. The ability to store energy is a big deal for solar energy systems, since they need to be able to save enough power to use at night or during days when the sun isn’t shining as brightly. UCLA’s technology isn’t quite ready yet, but Tolbert and her team are already trying to figure out how to incorporate it into real solar cells . [Image credit: Jason A.

The world’s thinnest light bulb is made from graphene

Forget LED light bulbs… in the future, your lighting may be made from carbon . Columbia University researchers have built a light bulb chip that superheats graphene to produce illumination. While that’s the same basic concept that you see in an incandescent bulb, the graphene filament measures just one atom thick — this is the world’s thinnest light bulb, and may be close to being the thinnest possible . It’s transparent, too, which could suit it to see-through displays . The technology should have uses beyond lighting things up, too. Generating this kind of heat on a small scale could lead to “micro-hotplates” that heat up chemicals for the sake of studying chemical reactions. Also, creating light at this scale is key to developing photonic processors that are much faster than conventional chips. The light will need to switch on and off much faster for any computing uses, but it’s a realistic possibility.

Rearranging jellyfish limbs may lead to self-healing robots

Normally when a jellyfish loses a limb, say to the jaws of a hungry sea turtle, it simply regenerates the lost appendage, no big deal. However, a Caltech research team has been studying a certain jellyfish species that doesn’t regrow its limbs but rather rearranges the remaining ones to maintain symmetry. They think that this body-modifying trick could one day help robots repair themselves after similar injuries. In a paper published June 15th in the Proceedings of the National Academy of Sciences (PNAS) the team described its work with the moon jellyfish. They amputated the various numbers of limbs from anesthetized jellies and then monitored their recovery. While the jellies healed in a couple of hours (as they normally do), the team noticed that rather than beginning to regrow their limbs the jellies instead shifted their remaining appendages around to restore their symmetry. What’s really wild is that mechanical forces created by the jelly’s own muscle contractions appear to be behind its reorganization. “This is a different strategy of self-repair, ” Caltech assistant professor of biology Lea Goentoro said in a statement. “Some animals just heal their wounds, other animals regenerate what is lost, but the moon jelly ephyrae [juveniles] don’t regenerate their lost limbs. They heal the wound, but then they reorganize to regain symmetry.” This discovery could lead to new advances in robotics . “Symmetrization may provide a new avenue for thinking about biomaterials that could be designed to ‘heal’ by regaining functional geometry rather than regenerating precise shapes, ” Goentoro continued. “Other self-repair mechanisms require cell proliferation and cell death-biological processes that aren’t easily translated to technology. But we can more easily apply mechanical forces to a material.” Soon, injured robots may not drag their broken limbs behind them like this little guy , but simply rearrange their other legs instead.

Here’s how Xbox One backward compatibility works

The Xbox 360 had a dedicated spot in millions of living rooms, bedrooms and offices for nearly 10 years, and during that time, players purchased massive libraries of games. However, when the Xbox One launched in 2013, it didn’t include the ability to play or transfer Xbox 360 games, a disappointment for many fans. That’s why Microsoft’s announcement at its E3 showcase was so exciting: The Xbox One is getting backward compatibility this holiday, with a lineup of more than 100 fan-requested Xbox 360 games to start and more to be added as demand warrants. Xbox One backward compatibility runs an Xbox 360 emulator right on the console, which is no easy feat, Microsoft General Manager of Games Publishing Shannon Loftis explains during a chat at E3. Are you pleased with the response to the announcement of backward compatibility on Xbox One? It’s something that I, as a gamer, have been wanting. Actually, the genesis of backwards compatibility is that gamers asked for it. It took some time for us to figure out how to do it, but we did and the response has been amazingly positive. How does it work, technologically? It wasn’t easy. It took some pretty dedicated engineering effort and very talented engineers. What they did was they created a software-based 360 emulation within the Xbox One architecture. So, when you put your disc in the drive, we’re actually loading up an emulator, and then we put up a little portion of the Xbox 360 dashboard and you use that dashboard to launch into your game. You still have access though to all the great Xbox One features: game streaming, game DVR, screenshots. It works for digital games as well and your saved games do transfer. Gamers have put so much into 360 games, so much passion, energy, time, money, and that value I think is important for us to bring into the Xbox One story. Will every Xbox 360 game eventually be available via backward compatibility? It’s up to gamers to tell us what they want . We do all the work, but there is a little bit of work and part of that involves talking with the publisher and making sure that this is consistent with their goals for the game as well. So, as gamers ask us, we will deliver. Check here for everything happening at E3 2015! Filed under: Gaming , HD , Microsoft Comments

CloudPlayer streams your music from Dropbox and Google Drive

DoubleTwist has released a media player separate from its main product, and this one can stream music straight from various cloud services. Aptly named CloudPlayer, the app links to your Dropbox, OneDrive and Google Drive accounts all at once to access any music files you’ve uploaded. The company says it “created CloudPlayer to provide an alternative to crippled, proprietary cloud music lockers that impose painful restrictions on what you can do with the music you own.” Unlike other services (company co-founder Jon Lech Johansen specifically targets Google Play Music in his blog post), DoubleTwist claims CloudPlayer doesn’t have a download or a device restriction, and it supports lossless audio. You can also choose songs and playlists to save for offline playback on the app. Finally, the media player can stream music through Chromecast and AirPlay devices (such as Apple TV), though you’ll have to shell out $5 for the feature as an in-app purchase. Otherwise, the app is free and up right now on Google Play — DoubleTwist says it’s “launching on Android first, ” so the player might head to other platforms in the future. A quick glance at the early reviews, however, shows that it’s having issues detecting music from OneDrive. The company says it’s a “bug with Microsoft’s OneDrive API, ” and it’s already taking steps to fix the problem. Filed under: Misc , Mobile Comments Via: Jon Lech Johansen’s blog Source: doubleTwist

Honeywell gets YouTube videos to play over global in-flight WiFi

The days of staying offline during your international flights might be coming to an end. Honeywell and Inmarsat have successfully stress-tested their global Ka-band satellite internet access in mid-air, doing everything from streaming YouTube videos to holding conference calls. The dry run shows that space-based broadband should be viable around the world, not just in certain areas — fly to Europe and your mid-trip WiFi connection should vaguely resemble what you have back home. It’ll take a while before airlines get the Honeywell/Inmarsat hardware on their fleets (ground, but one of the biggest challenges is over.

AT&T faces $100 million fine for quietly throttling data speeds

Look, it’s no secret that if you’ve got a old-school unlimited data plan from AT&T, your data speeds get throttled from time to time . Alright, it might be a bit of a secret — that’s why the FCC has just announced that it plans to slap the massive telecom with a $100 million fine for “severely” slowing down users’ connection speeds without adequately notifying them of the pokier speeds they might face. In case you haven’t been keeping count, that’s the single largest proposed fine in FCC history. A senior FCC official stated that service would at times get so slow that “basic mobile applications would not function, ” and that people who ran afoul of AT&T’s rules would get slower data speeds than others for an average of 12 days. First, though, a little recap. AT&T started offering unlimited data plans to its wireless customers in 2007, and finally stopped doing so in 2010. Here’s what happened a year after that, according to the FCC: AT&T implemented a “Maximum Bit Rate” policy and capped the maximum data speeds for unlimited customers after they used a set amount of data within a billing cycle. The capped speeds were much slower than the normal network speeds AT&T advertised and significantly impaired the ability of AT&T customers to access the Internet or use data applications for the remainder of the billing cycle. The news comes less than a week since the FCC’s new net neutrality rules officially took effect , but this investigation has been in the works for years now. That’s why the Commission is hanging its hat on the 2010 Open Internet Order, a troubled basket of oversight that basically got torn apart by Verizon in court last year. Verizon’s near-total legal win could have almost stopped the FCC’s investigation in its tracks, but the DC circuit court that heard the case upheld the Order’s stance on customer transparency so AT&T’s. Naturally, AT&T and sympathetic commissioners like Ajit Pai contend that the telecom did disclose the slowdowns, and that the FCC just ignored them all. Thing is, senior FCC officials didn’t think the disclosures AT&T did make were sufficiently straightforward. As far as they’re concerned, AT&T could’ve talked about its throttling program left, right and center, but it would’ve been meaningless unless those disclosures made clear what unlimited customers might run into.

Amazon’s delivery drones could be in the air within a year

Commercial drone operations like Amazon’s highly-touted delivery service could commence in about a year, according to a senior official from the Federal Aviation Administration. FAA Deputy Administrator Michael Whitaker told a congressional committee on Wednesday the necessary regulations for commercial UAVs to operate in public airspace will “be in place within a year.” That’s way shorter than the 2017 start date that the FAA originally figured on. And when the rules are finally settled on, Amazon will be ready. “We’d like to begin delivering to our customers as soon as it’s approved, ” Paul Misener, Amazon’s VP of global public policy, testified at the hearing. “We will have it (the technology) in place by the time any regulations are ready. We are working very quickly.” Amazon debuted the delivery drone idea way back in 2013 and began lobbying for FAA acceptance. This February, the FAA proposed that drones be allowed to operate only during daylight hours at a maximum height of 500 feet while staying within the pilot’s line of sight. However, since the regulations hadn’t been set in place at that point, Amazon had to take its initial flight tests to Canada . However, the FAA’s position has changed rapidly since March making it easier for companies to acquire operational permission and giving Amazon the ok to conduct drone tests ( in the continental US no less ). At this pace, the company may not need to move forward with its proposed crowdsourced delivery scheme . [Image Credit: Associated Press] Filed under: Amazon Comments Source: Reuters

California labor commission rules Uber drivers are employees

The California labor commission has ruled that an Uber driver qualifies as an employee, not a contractor, of the company. As a result Uber will have to reimburse a driver for expenses accumulated in the line of duty. That includes $256 in tolls and the IRS rate of $0.56 per mile for use of a personal vehicle for business purposes. But the total award of $4, 152.20 is not what scares the company, that’s pocket change seeing as how it was recently valued at roughly $50 billion . No, the king of cars-for-hire is afraid of the broader implications. If their current network of over one million drivers suddenly became employees, running the business could get a lot more expensive. For one, companies need to pay social security, payroll and medicare taxes for their employees. And it could have implications for the expectation of health or retirement benefits and even leave Uber vulnerable to renewed pressure from taxi unions . Of course, Uber is appealing the ruling and could keep this issue tied up in court for sometime. Plus, this ruling only applies in California for the time being, but it could be an omen of more trouble waiting on the horizon.
