Materials researchers use synthetic hydrogels which mimic the features of human muscles -- they''re strong, soft, full of water, and resistant to fatigue. Now researchers have discovered they mimic human muscles in another way, writes technology_dude: MIT researchers have found a way to give synthetic hydro gels human muscle characteristics: by taking the hyrdogels "to the gym"... The gym workout basically consisted of repeatedly stretching the material while in a water bath, [which] causes nanofibers to align "to produce a strong, soft, and hydrated material that resists breakdown or fatigue over thousands of repetitive movements," Phys.org reports.
The hydrogels can also be 3D-printed into different shapes, and the researchers believe the materials could one day be used for sensitive biomedical implants like heart valves, cartilage replacements, and spinal disks -- and for "soft robots."

In one of the most detailed descriptions yet of the relationship between Boeing and the Federal Aviation Administration during the 737 Max's certification process, the Seattle Times reports that the U.S. regulator delegated much of the safety assessment to Boeing and that the analysis the planemaker in turn delivered to the authorities had crucial flaws. 0x2A shares the report: Both Boeing and the FAA were informed of the specifics of this story and were asked for responses 11 days ago, before the second crash of a 737 MAX. [...] Several technical experts inside the FAA said October's Lion Air crash, where the MCAS (Maneuvering Characteristics Augmentation System) has been clearly implicated by investigators in Indonesia, is only the latest indicator that the agency's delegation of airplane certification has gone too far, and that it's inappropriate for Boeing employees to have so much authority over safety analyses of Boeing jets. "We need to make sure the FAA is much more engaged in failure assessments and the assumptions that go into them," said one FAA safety engineer. Going against a long Boeing tradition of giving the pilot complete control of the aircraft, the MAX's new MCAS automatic flight control system was designed to act in the background, without pilot input. It was needed because the MAX's much larger engines had to be placed farther forward on the wing, changing the airframe's aerodynamic lift. Designed to activate automatically only in the extreme flight situation of a high-speed stall, this extra kick downward of the nose would make the plane feel the same to a pilot as the older-model 737s.

Boeing engineers authorized to work on behalf of the FAA developed the System Safety Analysis for MCAS, a document which in turn was shared with foreign air-safety regulators in Europe, Canada and elsewhere in the world. The document, "developed to ensure the safe operation of the 737 MAX," concluded that the system complied with all applicable FAA regulations. Yet black box data retrieved after the Lion Air crash indicates that a single faulty sensor -- a vane on the outside of the fuselage that measures the plane's "angle of attack," the angle between the airflow and the wing -- triggered MCAS multiple times during the deadly flight, initiating a tug of war as the system repeatedly pushed the nose of the plane down and the pilots wrestled with the controls to pull it back up, before the final crash.

[...] On the Lion Air flight, when the MCAS pushed the jet's nose down, the captain pulled it back up, using thumb switches on the control column. Still operating under the false angle-of-attack reading, MCAS kicked in each time to swivel the horizontal tail and push the nose down again. The black box data released in the preliminary investigation report shows that after this cycle repeated 21 times, the plane's captain ceded control to the first officer. As MCAS pushed the nose down two or three times more, the first officer responded with only two short flicks of the thumb switches. At a limit of 2.5 degrees, two cycles of MCAS without correction would have been enough to reach the maximum nose-down effect. In the final seconds, the black box data shows the captain resumed control and pulled back up with high force. But it was too late. The plane dived into the sea at more than 500 miles per hour. [...] The former Boeing flight controls engineer who worked on the MAX's certification on behalf of the FAA said that whether a system on a jet can rely on one sensor input, or must have two, is driven by the failure classification in the system safety analysis. He said virtually all equipment on any commercial airplane, including the various sensors, is reliable enough to meet the "major failure" requirement, which is that the probability of a failure must be less than one in 100,000. Such systems are therefore typically allowed to rely on a single input sensor.

A new study from the Oxford Internet Institute claims to have found no link between time spent playing violent video games, and increased aggressive behavior teen teenagers. From a report: Published in Royal Society Open Science, the study is "one of the most definitive to date" according to the University of Oxford. While many studies have previously made similar and contrary claims, lead researcher professor Andrew Przybylski said the "idea that violent video games drive real-world aggression is a popular one, but it hasn't tested very well over time". According to the university, this study is set apart from previous work by preregistration, where researchers publish their hypothesis, methods and analysis technique before beginning research.

"Part of the problem in technology research is that there are many ways to analyze the same data, which will produce different results," said Przybylski. "A cherry-picked result can add undue weight to the moral panic surrounding video games. The registered study approach is a safeguard against this." This was supported by co-author Dr Netta Weinstein from Cardiff University who said: "Our findings suggest that researcher biases might have influenced previous studies on this topic, and have distorted our understanding of the effects of video games."

AmiMoJo quotes the Verge: The 2018 Hugo Awards were held Sunday night at the World Science Fiction Convention in San Jose, California. The Hugo award, voted on by members of the fan community, is considered the highest honour for science fiction and fantasy literature... N.K. Jemisin took home the top honor for The Stone Sky, the third installment of her Broken Earth trilogy. Other winners include Martha Wells for her first Murderbot novella All Systems Red, Suzanne Palmer for her novelette "The Secret Life of Bots," and Rebecca Roanhorse for her short story "Welcome to your Authentic Indian Experience." [Those last two links apparently let you read the entire story online!] Roanhorse also took home the John W. Campbell Jr. Award for Best New Writer.
Ursula K. Le Guin also posthumously won an award for "Best Related Work" for her collection of blog posts No Time to Spare: Thinking About What Matters.

And Zack Snyder finally won something, when Blade Runner 2049 lost in the "Best Dramatic Presentation -- Long Form" category to Wonder Woman ("screenplay by Allan Heinberg, story by Zack Snyder & Allan Heinberg and Jason Fuch.")

An anonymous reader shares a report: A panel of federal judges struck down North Carolina's congressional map on Tuesday, condemning it as unconstitutional because Republicans had drawn the map seeking a political advantage (Editor's note: the link may be paywalled; alternative source). The ruling was the first time that a federal court had blocked a congressional map because of a partisan gerrymander, and it instantly endangered Republican seats in the coming elections. Judge James A. Wynn Jr., in a biting 191-page opinion, said that Republicans in North Carolina's Legislature had been "motivated by invidious partisan intent" as they carried out their obligation in 2016 to divide the state into 13 congressional districts, 10 of which are held by Republicans. The result, Judge Wynn wrote, violated the 14th Amendment's guarantee of equal protection. The ruling and its chief demand -- that the Republican-dominated Legislature create a new landscape of congressional districts by Jan. 24 -- infused new turmoil into the political chaos that has in recent years enveloped North Carolina. President Trump carried North Carolina in 2016, but the state elected a Democrat as its governor on the same day and in 2008 supported President Barack Obama.

A medium-sized company just hired a new IT manager who wants advice from the Slashdot community about their two remaining IT "gofers": These people have literally been here their entire "careers" and are now near retirement. Quite honestly, they do not have any experience other than reinstalling Windows, binding something to the domain and the occasional driver installation -- and are more than willing to admit this. Given many people are now using Macs and most servers/workstations are running Linux, they have literally lost complete control over the company, with most of these machines sitting around completely unmanaged.

Firing these people is nearly impossible. (They have a lot of goodwill within other departments, and they have quite literally worked there for more than 60 years combined.) So I've been tasked with attempting to retrain these people in the next six months. Given they still have to do work (imaging computers and fixing basic issues), what are the best ways of retraining them into basic network, Windows, Mac, Linux, and "cloud" first-level help desk support?
Monster_user had some suggestions -- for example, "Don't overtrain. Select and target areas where they will be able to provide a strong impact." Any other good advice?

Leave your best answers in the comments. What's the best way to retrain old IT workers?

An anonymous reader points out that Frederick County Councilman Kirby Delauter may be in need of a First Amendment lesson. "Apparently, a local Maryland politician ditched his civics class the day press freedoms were discussed. How else to explain Frederick County Councilman Kirby Delauter's recent Facebook rant in which he threatened a local newspaper with litigation because—wait for it—his name was used in print without his permission. 'Use my name again unauthorized and you'll be paying for an Attorney. Your rights stop where mine start,' Kirby Delauter, the councilman, posted on his Facebook page. He added: 'So let me be clear.........do not contact me and do not use my name or reference me in an authorized form in the future.'"

Nicola Hahn (1482985) writes Kim Zetter of Wired Magazine has recently covered Dan Greer's keynote speech at Black Hat USA. In his lengthy address Greer, representing the CIA's venture funding arm, suggested that one way that the United States government could improve cyber security would be to use its unparalleled budget to buy up all the underground's zero-day vulnerabilities.

While this would no doubt make zero-day vendors like VUPEN and middlemen like the Grugq very wealthy, is this strategy really a good idea? Can the public really trust the NSA to do the right thing with all those zero-day exploits? Furthermore, recall the financial meltdown of 2008 where the public paid the bill for Wall Street's greed. If the government pays for information on all these unpatched bugs would society simply be socializing the cost of hi-tech's sloppy engineering? Whose interests does this "corner-the-market" approach actually serve?

An anonymous reader writes One of the developers behind special effects used in the film Avatar has inked a deal with airline check-in kiosk manufacturer BCS to implement avatars for personalized and interactive customer service. Dr Mark Sagar's Limbic IO is applying 'neurobehavioral animation' combining biologically based models of faces and neural systems to create live, naturally intelligent, and expressive interactive systems. "One of the comments levelled at self-service check in is that it has lost the human touch that people had when checking in at a traditional manned counter," Patrick Teo, BCS CEO says. "Travelling can be stressful and our aim is to make the interaction between human (passenger) and computer (check-in) as natural and helpful as possible."

BillCable writes: Politico reports, "In a major blow to the Washington Redskins, the U.S. Patent and Trademark Office on Wednesday canceled six federal trademarks of the 'Washington Redskins' team name because it was found to be 'disparaging' to Native Americans. 'We decide, based on the evidence properly before us, that these registrations must be canceled because they were disparaging to Native Americans at the respective times they were registered,' the PTO's Trademark Trial and Appeal Board wrote. The panel voted 2-1 in favor of the decision." Perhaps this move will speed up the inevitable name change, which was expected within the next few years."

MojoKid writes "A pirated version of an Android app is actually a Trojan that shames someone who installs it by sending an SMS message to all his/her contacts telling them of his/her piracy. The original app is called Walk and Text, and costs $2.10 in the Android Market. The app uses the camera on the back of a smartphone to show a user a visual of his upcoming surroundings, which will supposedly prevent the user from running into the street or across a set of train tracks. The pirated version is available from unofficial Android app markets, and once installed redirects the pirate to the legitimate app in the Android Market, while also sending the SMS message to the phone's entire contact list."
