After Death, Hundreds of Genes Spring Back to Life

Two surprising studies reveal new information about what genes do after death. Slashdot reader gurps_npc writes: You think your body stops after death, but up to two days later certain genes may turn on and start doing stuff for another two days before they give up the ghost. We are all zombies for up to four days after death. Gizmodo reports that in fact “hundreds” of genes apparently spring back to life. “[P]revious work on human cadavers demonstrated that some genes remain active after death, but we had no idea as to the extent of this strange phenomenon.” Read more of this story at Slashdot.

US Army’s smart earplugs spare soldiers from loud noises

As you might imagine, soldiers can’t just use garden variety earplugs to protect their ears. It might tone down the sounds of explosions and gunshots, but it’ll also prevent them from hearing a crucial command or an enemy on the other side of a doorway. It’s less of an issue for the US Army these days, though. The military branch has been gradually rolling out a smart earplug, TCAPS (Tactical Communication and Protective System), that adapts to the audio realities of war. The smartphone-linked device softens louder noises, but amplifies quieter ones; if your squad leader needs to issue a command, you’ll hear it over the din of battle. It’s a relatively simple system, but it’s very flexible. Some versions link to a soldier’s existing communications, and it’ll play nicely with hearing aids . TCAPS is far from ubiquitous. Only 20, 000 of the earplugs are in the field, and it’s doubtful that every single person in the infantry will get one when they cost around $2, 000 a pop. However, it stands a relatively good shot of catching on. More than anything, the technology provides confidence — you know you’ll get crucial audio cues without going deaf. Source: NPR

Scientists Announce Plans For Synthetic Human Genomes

An anonymous reader writes: After it was reported three weeks ago that scientists have held a secret meeting to consider creating a synthetic human genome, the participants of that meeting have officially published their plans. They announced a plan to launch a project that would radically reduce the cost of synthesizing human genomes — a revolutionary development in biotechnology that could enable technicians to grow human organs for transplantation. The Washington Post reports: “The announcement, published Thursday in the journal Science, is the latest sign that biotechnology is going through a rapidly advancing but ethically fraught period. The promoters of synthetic genomes envision a project that would eventually be on the same scale as the Human Genome Project of the 1990s, which led to the sequencing of the first human genomes. The difference this time would be that, instead of ‘reading’ genetic codes, which is what sequencing does, the scientists would be ‘writing’ them. They have dubbed this the ‘Genome Project-write.'” Read more of this story at Slashdot.

Researchers are using silk cocoons to store blood samples

When doctors draw blood for analysis, it’s vital that the sample either be immediately examined or refrigerated. That’s because the proteins which indicate various diseases will either be destroyed by enzymes in the blood or deformed by ambient heat. Either way, the sample quickly becomes useless if you leave it sitting out. However a team of researchers from Tufts University have developed a new way to store samples without having to put them on ice by using silkworm cocoons . The system works in a manner similar to conventional dried blood spot collection — wherein a drop of blood is deposited onto a piece of cardboard and allowed to dry. The Tufts method, however, relies on powdered silk and a separate silk-based solution. Mixing these two items with a sample of blood and allowing the result to dry preserved more viable blood proteins than both the normal drying or refrigeration methods. The team published its findings in the journal, Proceedings of the National Academy of Sciences on Monday. The technology itself is still very much in its preliminary development stages and won’t be showing up in your doctor’s office in the foreseeable future. Source: STAT News

Kodak is giving free film to Kickstarter directors

Crowdfunded filmmakers will be able to shoot on film for a lot less money thanks to a partnership between Kodak and Kickstarter. Kodak says it will provide free 35mm or Super 16mm film stock for select projects, up to a total of around $20, 000 for 35mm film, depending on the total budget. Beyond that, the company will provide discounted film and mentoring for packaging, financing and sales strategies. The choice of filmmakers appears to be at Kodak’s discretion, but so far the company has picked several Kickstarter productions that will launch this spring. Kickstarter has successfully funded 20, 000 productions totalling $330 million so far, though it didn’t say which were shot on film. The platform has garnered a lot of bad publicity in the past by funding large projects like Veronica Mars and Zach Braff’s Wish I Was Here , since the well-known producers probably could have raised the cash elsewhere. On the other hand, it’s an excellent platform for up-and-coming filmmakers, and has helped get Oscar-nominated projects with very small budgets off the ground. Kodak VP Anne Hubbell says that “Kodak understands that artists working at all budget levels strive to tell their stories with the unique quality and emotion that film provides.” The company points out that footage can be purchased by Kickstarter producers in eighteen countries, including the US, UK, France and Canada. Kodak’s situation is a lot more secure in the film industry since it struck a deal with Hollywood to supply film for the foreseeable future. DarkFall, a Kickstarter film backed by Kodak However, it’s equally likely that many young, inexperienced directors would rather shoot digital, given advantages like speed and the ability to easily review takes. As we have pointed out , the costs of shooting on film go way beyond the stock itself. Filmmakers also need to consider processing and transferring footage to a format that can be edited, color corrected and converted to a final screening format. That, combined with the lower sensitivity of film compared to digital cameras (which necessitates more complex lighting) means that the total budget will likely still be higher, even with the film thrown in. That said, it’s always good to have choices, so if it’s an aesthetic that a director absolutely can’t live without, good old celluloid is now a much more feasible option. Source: Kodak

Dropbox will soon show all your cloud-based files right in the desktop

If you’re one of the 500 million people who’ve used Dropbox at some point over the last few years, you know what you’re getting in to. It’s a reliable way to back up all the files on your computer, sync them across multiple devices and share them with friends, family or coworkers. It’s fast, it works and Dropbox has added a decent set of collaboration features over the years (like its strong Microsoft Office integration) — but by and large, its core “sync and share” features have remained largely the same. But today at the Dropbox Open event in London, the company is previewing an intriguing new feature called Project Infinite. In a nutshell, it looks to close the divide between our ever-increasing cloud storage vaults like Dropbox and the corresponding decrease in hard drive sizes. Back when Dropbox first launched, plenty of computers came with 500GB (or larger) hard drives, while paid Dropbox accounts only offered 50GB of space. However, since then, things have flip-flopped a bit — $10 a month gets you 1TB of Dropbox space, while the rise of SSD means that most computers have much smaller hard drives than that. And Dropbox for Business offers essentially limitless storage space, which means you’ll have to jump back and forth between files stored on your computer and Dropbox’s web interface to see everything you might want to access. Put simply, Project Infinite lets you see everything you have access to in Dropbox via your computer’s native interface (the Mac Finder or Windows Explorer). As before, files locally stored on your computer that are synced to Dropbox will have a green checkmark next to them, but everything else you might have access to will be visible as well. Those cloud-stored files will have a cloud icon next to them, but they’ll otherwise appear in your filesystem as if they’re stored on your hard drive. And if you want to open up those cloud files, you can just double-click. Dropbox will then download and open the file as if it was on your local storage, and any changes will be synced back to the cloud. It certainly sounds like it’ll be useful, as users will be able to store most of their digital materials in Dropbox and see it all on their computer without having to jump into Dropbox’s web interface. But there are some questions we have that are yet to be answered. It’s not clear if Project Infinite will be available to those paying $10 a month for Dropbox Pro or if it’ll only be available for business users. The Dropbox press release made it sound fairly focused on businesses, but hopefully consumers will also have access to the feature when it’s ready. There’s also no word on when the feature will be available. Dropbox says it’s testing Project Infinite with “a select number of sponsor customers” and says it’ll have more updates throughout the year, but there’s no word yet on when it’ll be widely available.

Australian researchers developed a blood test for Parkinson’s

By the time Parkinson’s disease makes itself known in humans, it’s already too late for treatment. But La Trobe University in Australia has developed a test that detects a biomarker present in blood cells in folks with the disease. The school describes the test as a means of detecting problems within cell mitochondria that cause an energy-and-stress-sensing protein, dubbed AMPK, to permanently activate and start damaging cells. The research is being bankrolled in part by Parkinson’s perhaps highest-profile patient, Michael J. Fox. Well, his foundation dedicated to further research on the debilitating malady , that is. The downside is that even with Fox’s Foundation for Parkinson’s Research and the Shake It Up Australia Foundation’s $640, 000 grant to La Trobe, more money is still needed for the test to be ready for the public. And beyond that, it’d still take five years to hit the market with additional funding. For now, the school is increasing the amount of testing it’s doing, going from a group of 38 people to 70. According to The Guardian , the ultimate goal is to do a longitudinal study with “thousands” of people in their 40s prior to them being at risk for the disease and before they start showing physical symptoms. From there, the researchers could test beyond Parkinson’s and see if the same method could be used to diagnose other neurological disorders, like Alzheimer’s, as well.

Intel’s Apollo Lake chips promise slimmer, beefier budget PCs

Intel’s Atom-based processors have gotten much better at delivering a lot of bang for the buck , but there’s still little doubt that you’re using a low-cost system. PCs like HP’s Stream series still tend to be thick, carry a meager amount of RAM and rule out intensive tasks like 4K video. You might not have to make quite so many sacrifices going forward, though: Intel has offered a peek at Apollo Lake, a next-generation system-on-a-chip that promises to inject some life into the budget category. It’s not only more compact, but efficient enough that PC makers can afford to slim things down without as many compromises — they can use smaller batteries without hurting battery life, for instance. The more inclusive design (should also save several dollars (around $5-7) in parts that can be rolled into more RAM, better displays and similar upgrades. There’s more than size and cost savings, of course. Apollo Lake borrows the graphics technology from Intel’s Skylake architecture, which brings full hardware-based 4K video playback and an overall boost to visual performance. It’ll also help drag lower-cost computers into the modern era with richer support for technologies like USB-C . Intel isn’t yet revealing clock speeds, pricing and a few other key details for its new platform, but it’s promising Celeron- and Pentium-branded processors in the second half of 2016. They won’t make you forget about higher-end Core CPUs when they ship, but they might just raise the bar for computing — that starter laptop or tablet won’t be as likely to choke on basic duties.

Homeland Security urges you to uninstall QuickTime on Windows

The Department of Homeland Security is echoing Trend Micro’s advice to uninstall QuickTime if you have it on your Windows computer. While the multimedia program’s working just fine, the security firm has discovered two new critical vulnerabilities lurking within it that could allow remote attackers to take over your system. Unfortunately, they might never be patched up: Trend Micro says Apple will no longer release security updates for the Windows version of the software, hence the call to jettison it completely. The good news is that Trend Micro hasn’t spotted any active attacks targeting those specific vulnerabilities yet. But both the firm and Homeland Security stress that because Apple has abandoned the program, the only way to protect yourself from potential threats is to dump it — Windows has a lot of safer alternatives you can use anyway. These flaws don’t affect QuickTime for Mac in any way, though, so OS X users can carry on. Source: Reuters , Department of Homeland Security , Trend Micro

AMC Theaters is considering letting people text during movies

Just as AMC Theaters was starting to win customers back by replacing every old seat in its auditoriums with recliners , the company wants to destroy that good will among moviegoers. That’s because CEO Adam Aron thinks letting people use their phones during a movie would be a good idea. “When you tell a 22-year-old to turn off their phone, don’t ruin the movie, they hear ‘please cut off your left arm above the elbow, ‘” Aron tells Variety . “You can’t tell a 22-year-old to turn off their cellphone. That’s not how they live their life.” Yes, he actually said that. This could be seen as an extension of recreating a home-like experience at a theater, vis a vis said recliner seats. But the difference here is that if you’re using your phone while watching a flick at home, you’re only affecting yourself and maybe your significant other — not the 100 or more people who paid to get into the theater. Movie theaters and places of worship are a few of the remaining places where using a cellphone is verboten, and by pandering to this demographic’s horrible habit AMC is stripping away common courtesy and setting a gross precedent in the name of profits. Aron says that certain sections where texting would be allowed is one possibility for this, while the more likely situation would be having specific auditoriums set up to be “more texting friendly.” If the chain is willing to kick out someone wearing Google Glass for fear of piracy, though, how is it going to differentiate someone texting from a person recording what’s on the screen with their phone? Contrast this with The Alamo Drafthouse which will happily eject you from a showing if you’re talking or texting, or won’t even let you into the auditorium if you’re late. As you can imagine, Twitter is lighting up with people decrying this , and for good reason: It’s an absolutely stupid move that could drive away already loyal customers in an effort to chase those it isn’t reaching anyway. “22-year-olds like to shoplift! What can we do??” — if the AMC CEO ran Macy’s — Scott Weinberg (@scottEweinberg) April 13, 2016 And that’s one way to keep me out of AMC theaters. Really hope they reconsider. https://t.co/DNthAggJIs — Chris Pugh (@ChrisLikesDinos) April 13, 2016 No @CEOAdam , I don’t want to go to a theater where people can text. We already have that, it’s a living room. #amctheaters — Rachel Stuhler (@RachelStuhler) April 13, 2016 Source: Variety
