In an effort to preserve rare varieties of chicken breeds and diversify the chicken gene pool, scientists at the University of Edinburgh's Roslin Institute have come up with a plan to breed genetically-modified chickens designed to act as surrogates that would be capable of laying eggs from any rare breed. Such rare breeds include the Nankin, Scots Dumpy and Sicilian Buttercup. The Guardian reports: The surrogacy technique, which places a new, mind-bending twist on the classic chicken or egg question, involves first genetically engineering hens to be sterile. This is done by deleting a gene, called DDX4, that is required for the development of primordial follicles (the precursors to eggs) meaning that the surrogate hens will never lay eggs that are biologically their own. The next step will be to transplant follicles from rare birds into the surrogate (this is done before the surrogate chick is hatched from its own egg), meaning it would go on to lay eggs belonging to entirely different breeds of chicken. Given that the hens would also need to be artificially inseminated with sperm from the same rare variety, the approach may appear unnecessarily convoluted. Why not just breed the rare birds the normal way? The scientists' ultimate goal is to create a gene bank of chicken breeds preserved for posterity, and since primordial follicles can be frozen efficiently, while eggs cannot, the surrogacy technique serves an essential work-around. Mike McGrew, who is leading the project and is the first author on a paper on the work published this week in the journal Development, predicts that the surrogates will be able to lay eggs from any breed, including chicken's wild predecessor, the red junglefowl, but he is doubtful about whether it will work efficiently across species -- it is not likely that the surrogate hens will be giving birth to eagle chicks, for instance. Richard Broad, a field officer for the Rare Breeds Survival Trust, agreed that rare chickens could be a source of valuable genetic variation, potentially carrying variants that would provide resistance against new forms of avian flu. At present, the team is focused on chicken breeds, but expects the technique to work to preserve rare varieties of ducks, geese and quail.

NASA announced today that their Juno spacecraft will not move into a closer orbit around Jupiter as originally planned. "Juno slipped into a highly elliptical, 53-Earth-day-long orbit around Jupiter when it arrived at the giant planet on July 4, 2016," reports Space.com. From their report: The probe was supposed to perform an engine burn in October to reduce its orbital period to 14 days, but an issue with two helium valves postponed that maneuver. The engine burn has now been canceled, meaning Juno will stay where it is through the end of its mission. "During a thorough review, we looked at multiple scenarios that would place Juno in a shorter-period orbit, but there was concern that another main engine burn could result in a less-than-desirable orbit," Rick Nybakken, Juno project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said in a statement. "The bottom line is, a burn represented a risk to completion of Juno's science objectives." But Juno should still be able to accomplish its mission goals in the longer orbit, NASA officials said. In fact, the 53-day path will allow the probe to perform some "bonus science" in the outer regions of Jupiter's magnetosphere, they added.

prisoninmate quotes a report from Softpedia: A year ago, we told you that, after ten long years, the Debian Project finally found a way to switch their rebranded Iceweasel web browser back to Mozilla Firefox, both the ESR (Extended Support Release) and normal versions, but one question remained: what about the Mozilla Thunderbird email, news, and calendar client? Well, that question has an official answer today, as the Mozilla Thunderbird packages appear to have landed in the Debian repositories as a replacement for Icedove, the rebranded version that Debian Project was forced to use for more than ten years due to trademark issues. "Thunderbird is back in Debian! We also renamed other related packages to use official names, e.g. iceowl-extension -> lightning. For now, we need testers to catch existing issues and things we haven't seen until now," said Christoph Goehre in the mailing list announcement. You can find out how to migrate your Icedove profiles to Thunderbird via Softpedia's report.

In the wake of security breach revelations, many of you might have considered deleting your Yahoo account. Many of you might be thinking about doing so soon. Heads up, it turns out, deleting a Yahoo email account isn't as straightforward as you may have imagined, and you again have Yahoo to blame for that. From a report on ZDNet: Several Yahoo users, who last year decided to leave the service, told us that their accounts remained open for weeks or months after the company said they would be closed. David Clarke was one of those departing users, whose dormant account was slowly accumulating junk over the past few years. "This was an ancient email I had set up, had no personal data in it anymore and had a unique password," writing about his troubles on Medium. "But it's a part of my digital footprint that I no longer required and decided, given the horrible security practices going on at Yahoo, to vote with my account and have it removed." Yahoo makes the account deletion process straightforward enough, but users have to wait "in most cases... approximately 90 days" for the account to close. The company says this is to "discourage users from engaging in fraudulent activity." On day 91, Clarke logged back into his account to find that it was still active. Unbeknownst to him, logging back in simply to check would reset the clock back to zero. "Yahoo confirmed via email yesterday if you access your account it resets the timer," he told me. "So, if you login to ensure your account has been deleted and it hasn't, you have to wait at least another 90 days."

Brian Fagioli, writing for BetaNews: System76 is refreshing three of its laptops with some high-end parts. The Oryx Pro, Serval WS, and Bonobo WS are now all equipped with 7th generation Intel Kaby Lake processors. In addition, all three can be had with 4K displays and NVIDIA GTX 10 series graphics too. While the Oryx Pro already had the option of 4K and GTX 10, it is the 7th gen Intel chips that are new to it. In fact, all of the company's laptops now come with Kaby Lake standard. The computer seller throws some shade at Apple by saying, "The HiDPI displays that ship on the laptops have 3.1 million more pixels than Apple's 'Retina' displays, enabling sharper text, 4K video, and higher res gaming. Beyond that, the displays give video and photo professionals the ability to work more easily with higher resolution multimedia."

Kitty Knowles, reporting for the Memo: Think you control what happens to your personal videos? Think again. One father who live-streamed his partner's labour on Facebook last May, has found out the hard way: he saw the birth of his son replayed on Good Morning America and numerous other media outlets. This week, he lost a high-profile court battle against the broadcasters. If you don't want this to happen to you, don't make the same mistakes. It's one thing wanting to share a life-changing moment with friends and family. But most would understand why Kali Kanongataa didn't want his child's birth aired for all to see. That hasn't however, stopped a US judge throwing out Kanongataa's copyright infringement case against the likes of the ABC, Yahoo, and Rodale, the company that publishes Women's Health. Apparently, the father-to-be realised his film was streaming publicly on social media about 30 minutes into recording, but decided to leave it that way. Media outlets broadcasting the clips have defended doing so on the terms of "fair use." Legally, "fair use" means that when pictures or videos are the focus of a major news story, selected footage can be used.Heads up, Facebook will soon release a video app for set-top boxes by Apple and Amazon to broadcast Live videos on the big screen.

An anonymous reader shares a report: During HTC's quarterly earnings call for Q4 2016, the company confirmed that it will not be producing new budget Android phones beginning this year. Instead, the company will focus on premium devices, which have a higher profit margin. On revenue of NT $22.2bn, the firm posted an operating loss of NT $3.6bn, and it's been some time since HTC showed a profit. Clearly, it's time to trim some of the fat. And that fat is producing a number of entry-level phones, many of which are nearly identical. For example, the Desire 530, which came to the US in July, had virtually no distinction from the Desire 626, which was introduced a year before.

Slashdot's more-jobs department:
Accenture said on Friday it would create 15,000 "highly skilled" new jobs in the United States, as IT services firms brace for a more protectionist U.S. technology visa program under President Donald Trump. From a report on Reuters: The company, which is domiciled in Dublin, Ireland, said the new jobs would increase the company's U.S. workforce by 30 percent to more than 65,000 by the end of 2020. Accenture has more than 394,000 employees, of which about 140,000 are in India. IT services companies have come under the spotlight after Trump said that his administration would focus on creating more jobs for U.S. workers, who had been affected by the outsourcing of jobs abroad. Major IT service companies, particularly those based in India, fly engineers to the United States using H-1B visas to service clients, but some opponents argue they are misusing the visa program to replace U.S. jobs.

Loon, the balloon project that aims to deliver internet to parts of the world that lack reliable connectivity, announced this week that due to advancements in the machine learning software, it can now deploy fewer balloons to provide greater connectivity. From a report on Recode: The Loon balloon project is part of X, the experimental division of Alphabet, Google's parent company. Now in its fourth year, the engineers at Loon say their new machine learning techniques significantly shorten their timeline for launching the project. Initially, engineers proposed that the Loon balloons would float around the globe and that they would have to find a way to keep the balloons a safe traveling distance apart and replace a balloon that drifted from an area that needed connectivity. Now, the team says they've found a way to keep the balloons in a much more concentrated location, thanks to their improved altitude control and navigation system. Loon says that balloons will now make small loops over a land mass, instead of circumnavigating the whole planet.
