XBMC’s Kodi media player officially hits the Play Store

Kodi’s media player got a name change last year and now it has something even better — official Android status. The app formerly known as XBMC is now available on the Google Play store for all takers. It actually arrived to the store last month in beta form , but prior to that could only be sideloaded on Android. Version 15 (codenamed Isengard) now supports Android 5-specific features like 4K and variable refresh rates on certain Android TV devices, like NVIDIA’s Shield . Another new trick on all platforms is “adaptive seeking” that lets you search material faster by tapping a key several times. There’s also new audio and subtitle lists, an updated add-on manager, improved video queuing and better live TV closed-captioning. It has other minor tweaks and fixes (check the source), and the XBMC foundation said that the next release would support DirectX 11. You can grab the app now on Google Play, but just remember that Kodi is a deep app, so leave yourself some time (and possibly some help ) to get it working.

Nanowires help produce hydrogen fuel using sunlight

You ideally want to produce clean hydrogen fuel using clean sources, and Dutch researchers have taken a big step toward making that a practical reality. They’ve built a solar cell that uses a grid of gallium phosphide nanowires to make hydrogen gas from water. The approach gets a useful yield of about 2.9 percent in lab tests. That may not sound like much, but it’s about 10 times more effective than previous techniques and uses 10, 000 times less exotic material. It’s still going to take more refinements before this kind of technology is practical. Even hooking up silicon cells to a battery nets a 15 percent yield, for example. If scientists improve their methods, though, you could be driving hydrogen cars whose fuel is eco-friendly at every step, not just when it’s in your vehicle.

Lockheed Martin buys helicopter maker Sikorsky

Don’t look now, but Lockheed Martin just became an even larger aerospace powerhouse. The aircraft maker has acquired helicopter maker Sikorsky (best known for the UH-60 Blackhawk) for $9 billion. The two have already been partners on programs like the MH-60, but this gives Lockheed its very own rotary-wing team. If a customer wants something that flies, the company will have it covered. The buyout is poised to close by late 2015 or early 2016, provided everything goes smoothly. The union might come at a stiff price, however. Lockheed says it’s conducting a “strategic review” of both its information systems group and a chunk of its missile division — tough times in the market have led Lockheed to believe that these segments would be better-off either spun out or sold to someone else. That puts the future of more than 17, 000 workers in doubt, and that’s not including whatever jobs might be cut when the Sikorsky deal wraps up.

Plastic roads may put asphalt to shame

The days of putting up with crumbling asphalt streets might just come to an end. Construction company VolkerWessels has revealed plans for recycled plastic roads that are both more sustainable and more practical than old-fashioned blacktop. Besides reusing material, they’d last about three times longer and survive greater temperature ranges (between -40F and 176F) — despite their fragile look, they’re less likely to crack under the strain of vehicles or the weather. You can pre-assemble them to lay them down faster, too, and their hollow structure is handy for cabling and pipes. This is just a concept at the moment, but VolkerWessels fully intends to test it and make sure that it holds up in the real world. That’s not idle talk, either. The Dutch city of Rotterdam is interested in trying out these plastic surfaces in its “street lab, ” and the company hopes to have an honest-to-goodness route in operation within three years. If the idea still sounds outlandish, look at it this way: it’s likely the closest you’ll ever get to driving a Hot Wheels track in real life.

Google continues to make money thanks to mobile and YouTube

While Google has been enjoying consistent financial growth for quite some time, it was dinged the last two quarters for not living up to Wall Street expectations. But in today’s Q2 earnings announcement, the Mountain View firm has made significant strides in rectifying that reputation. It reported a revenue of $17.7 billion this past quarter, which is an 11 percent growth year over year and a 3 percent growth since Q1. This has beat Wall Street estimates handily, causing its stock to climb by 11 percent at closing. What’s contributing to this success? As CFO Ruth Porat puts it, it’s all thanks to mobile, with YouTube playing a star role. Though Google won’t reveal specific numbers, Porat said that “the gap between mobile and desktop continues to narrow” when it comes to the money it makes from advertising. There’s apparently been a particularly strong surge in mobile search , which is a significant contributor to ad revenue. Chief Business Officer Omid Kordestani said on the earnings call that “more searches happen on mobile than computers in 10 countries.” It’s why the company is putting even more resources behind creating a better mobile experience. He says that around 30 percent of mobile searches are location-related — perhaps they want to know what’s around them or where’s the closest gas station. “When people search on mobile, they want immediacy and action, ” he said. It’s not just search either. Google has also invested in other key mobile experiences, especially in a world where people are less likely to head directly to google.com to search. Kordestani states that efforts like Google Photos , Now On Tap and Android Pay all factor in to making Google’s mobile presence more widespread. He also credited deep linking — where users are led to install new apps from links within other apps — for a boost in traffic. Indeed, Porat said that Google Play “continues to grow at an impressive clip” and is the “fastest growing mobile gaming platform.” What’s particularly impressive is that YouTube ad revenue has also blossomed, particularly in mobile. The ” Trueview ” ad format — basically all those pre-roll ads you see before YouTube clips — has really grown of late. Porat said that YouTube has experienced an accelerated 16 percent growth rate and that “mobile watch time has more than doubled.” Cost per clicks have gone down, but that’s alright as those aforementioned Trueview ad hits have increased. A new feature of Trueview that automatically adds product information and pricing in video ads is cited for the growth. Indeed, the number of advertisers running ads on YouTube has gone up by 40 percent and the average spend is up by 60 percent. Kordestani said that the average viewing time on YouTube is also more than 40 minutes and that more 18 to 49 year olds watch YouTube on mobile than any cable network. He said YouTube is great for content creators too, as the number of channels making six figures is up by 50 percent from this time last year. As for Google’s other projects — Nest , Fiber and Google Life Science s — those are now under “tighter governance” and are seen as more longer-term sources for revenue. Which basically means that they’re not quite making money hand over fist from those units just yet, but the potential is there.

Intel delays next-gen chips as Moore’s law begins to crack

Intel says it’s next-gen ” Skylake ” will be delayed by six months, marking the second time in a row it hasn’t released a CPU on a two-year “Moore’s Law” cycle. That continues a trend, as last year’s 14-nanometer Broadwell chips were similarly delayed , and even Haswell and Ivy Bridge were behind schedule. Intel said that the setback for the new 10-nanometer chips was caused by the increasing complexity in building transistors that small. Addressing the elephant in the room, CEO Brian Krzanich said that “the last two technology transitions have signaled that our cadence today is closer to 2.5 years than two.” In other words, Moore’s Law needs a reboot. To address the lack of chips in the pipeline, Intel said that it’s going to release new 14-nanometer “Kaby Lake” chips based on the Skylake architecture. Krzanich said that “we expect that this addition to the roadmap will deliver new features and improved performance, and pave the way for a smooth transition to 10-nanometer.” Neverthless, he admitted that Intel is now on a “tick-tock-tick” cycle rather than a “tick-tock” as before. That bodes poorly for an already-struggling PC industry, as consumers will have less reason to get excited about new products. Intel also admitted that PC demand was weaker than expected, and expects it to get worse by year’s end. Nevertheless, it thinks the July 29 launch of Windows 10 will provide a tonic. “A lot of the really good features of Windows 10, things like Windows 10 Hello where you have facial log in, and you don’t have to use all your passwords, the Start screen… the touch usages of gaming, as the new games come to this product — those are going to run with PCs that have the latest features, ” Krzanich said. Despite the gloomy PC talk, Intel still managed to pull in a better-than-expected $13.2 billion for the quarter, thanks to a new focus on data centers, internet-of-things and memory.

UW-Madison researchers invent a metal-free fuel cell

The development of fuel cell technology has been hamstrung by the need for expensive and difficult-to-manufacture catalysts like platinum , rhodium or palladium. But a team of researchers from the University of Wisconsin-Madison believe they’ve found an ingenious alternative that employs a molecular, rather than solid, catalyst . A fuel cell generates electricity from chemicals by reacting hydrogen and oxygen at its anode and cathode , respectively. Specifically, a catalyst at the anode oxidizes the hydrogen fuel to create free electrons and charged ions. The ions pass through the electrolyte while the electrons pass through a separate wire (to drive an electronic device) and the two recombine in the cathode with oxygen to create water or CO2. The team, led by Professor Shannon Stahl and lab scientist James Gerken, noticed that the aerobic oxidation reactions they had studied in their previous work closely mimicked the oxygen reaction in fuel cells. To see if this aerobic reaction could work as a fuel cell, they built one using a catalyst composed of nitroxyl and nitrogen oxide molecules to react with its electrode and oxygen. “While this catalyst combination has been used previously in aerobic oxidations, we didn’t know if it would be a good fuel cell catalyst, ” Stahl said in a statement. “It turns out that it is the most effective molecular catalyst system ever reported.” The results are more than impressive. “This work shows for the first time that molecular catalysts can approach the efficiency of platinum, ” Gerken continued. “And the advantage of molecules is that you can continue to modify their structure to climb further up the mountain to achieve even better efficiency.” [Image Credit: Getty Images/iStockphoto] Filed under: Science Comments Source: University of Wisconsin-Madison

5G Network Speed Defined As 20 Gbps By the International Telecommunication Union

An anonymous reader writes with a report at Mobipicker (linking to a Korea Times story) that a 12-member committee from the International Telecommunication Union has hashed out a formal definition of the speed requirements for 5G mobile networking; the result has been designated IMT-2020, and it specifies that 5G networks should provide data speeds of up to 20Gbps — 20 times faster than 4G. From the Korea Times story: The 5G network will also have a capacity to provide more than 100 megabits-per-second average data transmission to over one million Internet of Things devices within 1 square kilometer. Video content services, including ones that use holography technology, will also be available thanks to the expanded data transmit capacity, the ministry said. … The union also decided to target commercializing the 5G network worldwide by 2020. To do so, it will start receiving applications for technology which can be candidates to become the standard for the new network. Consequently, the 2018 PyeongChang Winter Olympic Games will be the world’s first international event to showcase and demonstrate 5G technology. Read more of this story at Slashdot.
