FDA approves first GM food animal—Atlantic salmon

(credit: Artizone/Flickr ) After two decades of deliberation, the Food and Drug Administration has approved the first ever genetically engineered food animal, a fast-growing Atlantic Salmon called AquAdvantage salmon. According the agency, which announced the approval Thursday , the modified salmon are safe to eat, equally nutritious as other salmon, and should pose no threat to the environment. First created in 1989 and submitted to the agency for approval in 1995, the Atlantic salmon are modified to carry a growth hormone gene from Chinook salmon. That gene is further engineered to be under the control of a tiny bit of DNA, called a promoter, from the eel-like ocean pout fish. In general, DNA promoters are non-coding sequences that help control the expression level of a gene—how much protein product is synthesized from the gene. With the engineered promoter boosting hormone production, the modified salmon grow to market-size in about half the time of conventional Atlantic salmon. Read 4 remaining paragraphs | Comments

Visual Studio now supports debugging Linux apps; Code editor now open source

The Visual Studio Code editor, now open source, editing TypeScript on OS X. (credit: Microsoft) NEW YORK—Developers can now debug apps running on Linux servers or IoT devices from the comfort of Visual Studio. Microsoft today released a preview of a Visual Studio extension that adds remote debugging using GDB of Linux software. This was one of many announcements made at Microsoft’s Connect developer event today as the company aims to give its developer platform the broadest reach it’s ever had, able to handle Android, iOS, and Linux development, alongside the more expected Azure, Office, and Windows. Visual Studio 2015 already made big strides in this direction, and Microsoft is pushing ahead to try to make Visual Studio the best development environment around. The free and cross-platform Chromium-based code editor Visual Studio Code is being open sourced today. A new build has also been published, adding an extension mechanism to the editor. There are already some 60 extensions available, including new language support (such as Go language), richer debugging, code linters, and more. Read 10 remaining paragraphs | Comments

Feds bugged steps of Silicon Valley courthouse

(credit: James Vaughan ) Defense attorneys have asked a federal judge to throw out more than 200 hours of conversations FBI agents recorded using hidden microphones planted on the steps of a California county courthouse. The lawyers are representing defendants accused of engaging in an illicit real estate bid-rigging and fraud conspiracy. The steps to the San Mateo County courthouse are frequently the scene of public auctions for foreclosed homes. Federal prosecutors have admitted that on at least 31 occasions in 2009 and 2010, FBI agents used concealed microphones to record auction participants as they spoke, often in hushed voices with partners, attorneys, and others. Because the federal agents didn’t obtain a court order, the defense attorneys argue the bugging violated Constitutional protections against unreasonable searches and seizures. In a court brief filed Friday in the case, attorneys wrote: Read 4 remaining paragraphs | Comments

Single course of antibiotics can mess up the gut microbiome for a year

(credit: Global Panorama/Flickr ) In a battle against an infection, antibiotics can bring victory over enemy germs. Yet that war-winning aid can come with significant collateral damage; microbial allies and innocents are killed off, too. Such casualties may be unavoidable in some cases, but a lot of people take antibiotics when they’re not necessary or appropriate. And the toll of antibiotics on a healthy microbiome can, in some places, be serious, a new study suggests. In two randomized, placebo-controlled trials of healthy people, a single course of oral antibiotics altered the composition and diversity of the gut microbiome for months, and in some cases up to a year. Such shifts could clear the way for pathogens, including the deadly Clostridium difficile . Those community changes can also alter microbiome activities, including interacting with the immune system and helping with digestion. Overall, the data, published Tuesday in the journal mBio , suggests that antibiotics may have more side effects than previously thought—at least in the gut. In the mouth, on the other hand, researchers found that microbial communities fared much better, rebounding in weeks after antibiotic treatments. The finding raises the question of why the oral microbiome is less disturbed by drugs. It could simply be because of the way that antibiotics, taken orally, circulate through the body. Or, it could imply that oral microbiomes are innately more resilient, a quality that would be useful to replicate in microbial communities all over the body. Read 6 remaining paragraphs | Comments

Utility-scale solar costs down by half in last five years alone

Earlier this week, Lawrence Berkeley National Labs released a report on the state of utility-scale solar installations in the US. Just about everything in the report is remarkable for anyone who’s followed the solar market closely. Over the past five years, prices have dropped by half, while the capacity factors are approaching that of wind. As a result, the most recent installations are offering power at prices that are competitive with natural gas—not the cost of the plant and fuel, but the fuel alone. In 2014, utility-scale solar projects added about 4GW of capacity to the US grid. Slightly more than 6GW of solar capacity was added in total, with the remainder split between commercial and residential installs. Due to the rapid drop in prices, the majority of this capacity is in the form of photovoltaic panels. One of the issues with utility-scale solar has been that some of the earlier plants were built outside the Southwest. This has meant less overall generation and a lower capacity factor, meaning that the panels are only producing power at a fraction of their maximal rate. Both of these raise the cost of the electricity generated. But installations in the Southwest have boomed to over 90 percent of the total installed hardware. This has capacity factors up and costs down. More recently, large projects have been getting more popular in the Southeast, which may change this dynamic in the future.

iOS 9’s space-saving “app slicing” disabled for now, will return in future update

Enlarge / Apple’s sample universal binary here is just 60 percent of its original size when downloaded to an iPad or iPhone. (credit: Andrew Cunningham) Back in June, we wrote a bit about App Thinning , a collection of iOS 9 features that are supposed to make iOS 9 apps take up less space on iDevices. Apple has just announced to developers that one of those features, “app slicing,” is not available in current iOS 9 versions due to an iCloud bug. It will be re-enabled in a future iOS update after the bug has been resolved. App slicing ensures that your iDevice only downloads the app assets it needs to work. In older versions of iOS, all devices downloaded “universal” versions of apps that included all of the assets those apps needed to work on each and every targeted iDevice. If you downloaded an app to your iPhone 5, for example, it could include larger image assets made for the larger-screened iPhones 6 and 6 Plus, 64-bit code that its 32-bit processor couldn’t use, and Metal graphics code that its GPU didn’t support. That’s all wasted space, a problem app slicing was designed to resolve. Apple says the iCloud bug affects users who are restoring backups to new devices—if you moved from that iPhone 5 to a new iPhone 6S, for example, iCloud would restore iPhone 5-compatible versions of some apps without the assets required by the newer, larger device.

Supermassive black holes found spiraling in at seven percent light speed

Simulation of the pair of supermassive black hole binary system, PG 1302-102. The smaller shines more brightly because it’s farther from the center of mass, and thus closer to the outer disk of gas. This gas accretes onto the black hole, heating up as it falls in, and thus emits more light. The more massive black hole, therefore, is starved of gas and doesn’t glow as brightly. (credit: Zoltan Haiman, Columbia University ) Data from NASA’s Galaxy Evolution Explorer ( GALEX ) and the Hubble Space Telescope has confirmed the presence of a pair of supermassive black holes orbiting each other so closely that they’re moving at relativistic speeds—a significant fraction of the speed of light. Supermassive black holes are expected to come in pairs pretty often. That’s because every galaxy has its own supermassive black hole, and galaxies often merge, bringing the two together. These mergers are very slow processes that distort both galaxies until their stars settle into new orbits (a process known as “violent relaxation”). While this is happening, extremely heavy objects, such as supermassive black holes, will tend to move in toward the center of the new galaxy. The new galaxy would end up with two supermassive black holes, one from each original galaxy, orbiting each other at its core. Objects have been observed which look a lot like supermassive black hole binaries, matching the prediction. These objects have a lot of mass—billions of times the mass of the Sun, as we’d expect from a pair of supermassives—and they’re periodic, meaning the amount of light the object produces rises and falls with a predictable time period.

Finally, game cartridges you can plug in to your smart phone

Downloading games directly to your smartphone and playing them immediately is convenient, I suppose. But this ephemeral, bloodless process is missing a familiar tangibility gamers might remember warmly from the last millennium: that comforting, solid, life-affirming feeling of jamming a game cartridge into a console slot. Enter Pico Cassette , a Japanese outfit that says it’s bringing back “the next retro” with tiny game cartridges that plug in to a smartphone’s headphone jack. The tiny “cassettes” (the general Japanese term for cartridges) are built on PlugAir technology , which uses a specially designed iPhone or Android app to draw power from the headphone jack and send data using specially modulated sound waves. Those coded sound waves are then used to unlock access to content that’s stored in the cloud, according to a PlugAir explanation video . That would seem to remove one of the main conveniences of the physical cartridge format—namely, distributing and storing data permanently without an Internet connection—but there’s nothing technical preventing the actual game data from being stored on the cartridges as well. In any case, there’s something about the simplicity of being able to share a game with a friend simply by handing them a physical thing that plugs in to the phone (though the need for a special app is a bit of an impediment to immediate ad-hoc sharing).

Songwriter tells US House he made $5,679 from 178 million Spotify streams

The songwriter who co-wrote Megan Trainor’s “All About That Bass” alleged on Tuesday that he only cleared $5,679 from over 178 million streams of the song on Spotify. (credit: YouTube ) A Tuesday copyright roundtable discussion, hosted by Nashville’s Belmont University and led by the House Judiciary Committee, opened with one of the past year’s most successful songwriters announcing just how little money he’d made from over 178 million streams of a song he co-wrote: $5,679. That means Nashville songwriter Kevin Kadine, the co-writer of the hit 2014 Megan Trainor song “All About That Bass,” made close to $31.90 for every million streams. According to a report by The Tenneseean , Kadine didn’t clarify to the roundtable’s five members of the House of Representatives exactly how the songwriting proceeds were split between himself and Trainor (who shared songwriting credits on “Bass”), but he did allege that the average streaming-service payout for a song’s songwriting team is roughly $90 per million streams. “That’s as big a song as a songwriter can have in their career, and number one in 78 countries,” Kadine said. “But you’re making $5,600. How do you feed your family?” Read 4 remaining paragraphs | Comments

France tells Google to remove search results globally, or face big fines

Public domain. Google’s informal appeal against a French order to apply the so-called “right to be forgotten” to all of its global Internet services and domains, not just those in Europe, has been rejected. The president of the Commission Nationale de l’Informatique et des Libertés (CNIL), France’s data protection authority, gave a number of reasons for the rejection , including the fact that European orders to de-list information from search results could be easily circumvented if links were still available on Google’s other domains. CNIL’s president also claimed that “this decision does not show any willingness on the part of the CNIL to apply French law extraterritorially. It simply requests full observance of European legislation by non European players offering their services in Europe.” As you’ve probably gathered, Google disagrees with CNIL’s stance. In a July blog post regarding the case, the company’s global privacy chief, Peter Fleischer, wrote: “If the CNIL’s proposed approach were to be embraced as the standard for Internet regulation, we would find ourselves in a race to the bottom. In the end, the Internet would only be as free as the world’s least free place. We believe that no one country should have the authority to control what content someone in a second country can access.” Read 3 remaining paragraphs | Comments
