It's now easier than ever in France to act out Star Wars fantasies. The country's fencing federation has officially recognized lightsaber dueling as a competitive sport, granting the weapon from George Lucas's space saga the same status as the foil, epee and sabre, the traditional blades used at the Olympics. From a report: Of course, the LED-lit, rigid polycarbonate replicas can't slice an opponent in half. But they look and sound remarkably like the blades that Yoda and other characters wield in the blockbuster movies. The physicality of lightsaber combat is part of the reason why the French Fencing Federation is now equipping fencing clubs with lightsabers and training would-be lightsaber instructors. Like virtuous Jedi knights, the federation sees itself as combatting a Dark Side: the sedentary habits of 21st-century life.
"With young people today, it's a real public health issue. They don't do any sport and only exercise with their thumbs," says Serge Aubailly, the federation's secretary general. "That is why we are trying to create a bond between our discipline and modern technologies, so participating in a sport feels natural." In the past, Zorro, Robin Hood and The Three Musketeers helped lure new practitioners to fencing. Now, Luke Skywalker, Obi-Wan Kenobi and Darth Vader are joining them. "Cape-and-sword movies have always had a big impact on our federation and its growth," Aubailly says. "Lightsaber films have the same impact. Young people want to give it a try."

Mark Gurman, reporting for Bloomberg: Apple wants to make it easier for software coders to create tools, games and other applications for its main devices in one fell swoop -- an overhaul designed to encourage app development and, ultimately, boost revenue. The ultimate goal of the multistep initiative, code-named "Marzipan," is by 2021 to help developers build an app once and have it work on the iPhone, iPad and Mac computers, said people familiar with the effort. That should spur the creation of new software, increasing the utility of the company's gadgets.
Later this year, Apple plans to let developers port their iPad apps to Mac computers via a new software development kit that the company will release as early as June at its annual developer conference. Developers will still need to submit separate versions of the app to Apple's iOS and Mac App Stores, but the new kit will mean they don't have to write the underlying software code twice, said the people familiar with the plan. In 2020, Apple plans to expand the kit so iPhone applications can be converted into Mac apps in the same way. Further reading: Tim Cook, in April 2018: Users Don't Want iOS To Merge With MacOS.

technology_dude writes: One by one, thresholds are being crossed where the collection and storage of personal data is accepted as routine. Being recorded by cameras at business locations, in public transportation, in schools, churches, and every other place imaginable. Recent headlines include "Singapore Airlines having cameras built into the seat back of personal entertainment systems," and "Arizona considering a bill to force some public workers to give up DNA samples (and even pay for it)." It seems to be a daily occurrence where we have crossed another line in how far we will go to accept massive surveillance as normal. Do we even have a line the sand that we would defend? Do we even see anything wrong with it? Absolute power corrupts absolutely and we continue to give knowledge of our personal lives (power) to others. If we continue down the same path, I suppose we deserve what we get? I want to shout "Stop the train, I want off!" but I fear my plea would be ignored. So who out there is more optimistic than I and can recommend some reading that will give me hope? Bill 1475 was introduced by Republican State Senator David Livingston and would require teachers, police officers, child day care workers, and many others to submit their DNA samples along with fingerprints to be stored in a database maintained by the Department of Public Safety. "While the database would be prohibited from storing criminal or medical records alongside the DNA samples, it would require the samples be accompanied by the person's name, Social Security number, date of birth and last known address," reports Gizmodo. "The living will be required to pay [a $250 processing fee] for this invasion of their privacy, but any dead body that comes through a county medical examiner's office would also be fair game to be entered into the database."

Scientists think they've identified a previously unknown form of neural communication that self-propagates across brain tissue, and can leap wirelessly from neurons in one section of brain tissue to another -- even if they've been surgically severed. The discovery offers some radical new insights about the way neurons might be talking to one another, via a mysterious process unrelated to conventionally understood mechanisms, such as synaptic transmission, axonal transport, and gap junction connections. ScienceAlert reports: "We don't know yet the 'So what?' part of this discovery entirely," says neural and biomedical engineer Dominique Durand from Case Western Reserve University. "But we do know that this seems to be an entirely new form of communication in the brain, so we are very excited about this." To that end, Durand and his team investigated slow periodic activity in vitro, studying the brain waves in This neural activity can actually be modulated - strengthened or blocked - by applying weak electrical fields and could be an analogue form of another cell communication method, called ephaptic coupling.
The team's most radical finding was that these electrical fields can activate neurons through a complete gap in severed brain tissue, when the two pieces remain in close physical proximity. slices extracted from decapitated mice. What they found was that slow periodic activity can generate electric fields which in turn activate neighboring cells, constituting a form of neural communication without chemical synaptic transmission or gap junctions. "To ensure that the slice was completely cut, the two pieces of tissue were separated and then rejoined while a clear gap was observed under the surgical microscope," the authors explain in their paper. "The slow hippocampal periodic activity could indeed generate an event on the other side of a complete cut through the whole slice." The findings are reported in The Journal of Physiology.

An anonymous reader quotes a report from CNN: The U.S. Food and Drug Administration warned Tuesday against using plasma infusions from young blood donors to ward off the effects of normal aging as well as other more serious conditions. Plasma, the liquid portion of the blood, contains proteins that help clot blood. The infusions are promoted to treat a variety of conditions, including normal aging and memory loss as well as serious conditions such as dementia, multiple sclerosis, heart disease and post-traumatic stress disorder.
"There is no proven clinical benefit of infusion of plasma from young donors to cure, mitigate, treat, or prevent these conditions, and there are risks associated with the use of any plasma product," FDA Commissioner Dr. Scott Gottlieb wrote in a statement Tuesday. "The reported uses of these products should not be assumed to be safe or effective," he added, noting that the FDA "strongly" discourages consumers from using this therapy "outside of clinical trials under appropriate institutional review board and regulatory oversight." Gottlieb said that "a growing number of clinics" are offering plasma from young donors and similar therapies, though he did not name any in particular.

Cybersecurity firm Crowdstrike says China has largely abandoned a hacking truce negotiated by Barack Obama as President Trump embarked on a trade war with Beijing last year. "A slowdown in Chinese hacking following the cybersecurity agreement Obama's administration secured in 2015 appears to have been reversed, the firm said in a report released Tuesday that reviewed cyber activity by U.S. adversaries in 2018," reports Bloomberg. From the report: The report comes as the Trump administration seeks to reach a trade deal with China, including provisions on intellectual property theft, ahead of a March 1 deadline. Trump has said he may extend that deadline and hold off on increasing tariffs on Chinese imports if there's progress in the talks. China's hacking targets in 2018 included telecommunications systems in the U.S. and Asia, according to Crowdstrike. Groups linked to Iran and Russia also appeared to target telecommunications, a sector that yields "the most bang for your buck" for hackers due to the large number of users that can be accessed after breaching a single network, Meyers said.
The findings align with concern in the U.S. about telecommunications security as the country transitions to the next generation of mobile networks and the Trump administration seeks to secure so-called 5G technology from foreign intelligence gathering. The administration has expressed particular concern about the spread of products made by the Chinese firm Huawei Technologies Co. The report also mentions the increased cyber activity in other parts of the world. "Iran focused much of its cyber activity on Middle Eastern and North African countries while Russia engaged in intelligence collection and information operations worldwide," the report says. "North Korea deployed hackers for financial gain and intelligence collection, while China targeted sectors including technology, manufacturing and hospitality."

In preparation for the Galaxy S10 launch event tomorrow, The Verge's Dieter Bohn writes about the new "One UI" software that will run on these new phones. After testing the software on a Galaxy S9 for the past week, Bohn says he really likes it, adding that it's better in some ways than the software found on Google's Pixel 3. "If it weren't for the fact that I don't yet trust Samsung to deliver major software updates quickly, I would be shouting about One UI from the rooftops," writes Bohn. "As it is, I just want to point out that it's time for us to stop instinctively turning our noses up at Samsung's version of Android." From the report: I can't go quite so far as to say that everything has changed forever when it comes to Samsung's customizations. There are still multiple versions of some apps because both Google and Samsung insist on having their software present. Samsung phones also have a reputation for getting a little laggy (the technical term is cruft) over time, and I don't know yet whether One UI and Android 9 will suffer the same fate. But I do know that one week in, this OS actually feels intentional and designed instead of just having a bunch of features tacked on. Historically, we've thought of all those customizations as unnecessary add-ons. But that's not quite right anymore -- customizing AOSP is necessary these days. Instead, we should judge a Samsung phone on its own merits as a phone, not as stuff bolted on to some idealized "pure" version of the phone that can't really exist anymore.

An anonymous reader quotes a report from the BBC: Current digital technology gives us flawless music quality without physical deterioration. Music is easy to copy and upload, and can be streamed online without downloading. Since our digital music is less tangible than vinyl or CDs, surely it must be more environmentally friendly? Even though new formats are material-free, that doesn't mean they don't have an environmental impact. The electronic files we download are stored on active, cooled servers. The information is then retrieved and transmitted across the network to a router, which is transferred by wi-fi to our electronic devices. This happens every time we stream a track, which costs energy. Once vinyl or a CD is purchased, it can be played over and over again, the only carbon cost coming from running the record player. However, if we listen to our streamed music using a hi-fi sound system it's estimated to use 107 kilowatt hours of electricity a year, costing about $20 to run. A CD player uses 34.7 kilowatt hours a year and costs about $7 to run.
So, which is the greener option? It depends on many things, including how many times you listen to your music. If you only listen to a track a couple of times, then streaming is the best option. If you listen repeatedly, a physical copy is best -- streaming an album over the internet more than 27 times will likely use more energy than it takes to produce and manufacture a CD. If you want to reduce your impact on the environment, then vintage vinyl could be a great physical option. For online music, local storage on phones, computers or local network drives keeps the data closer to the user and will reduce the need for streaming over distance from remote severs across a power-hungry network.

Slashdot's unsafe-levels-of-radiation department:
joeflies writes: Park safety manager Elston Stephenson provides details about buckets of uranium that exposed visitors to radiation, and the subsequent cover up. The radiation was detected by a teenager that brought a Geiger counter to the building, and was subsequently "cleaned" up by employees equipped with dish washing gloves and a broken mop handle. "If you were in the Museum Collections Building (2C) between the year 2000 and June 18, 2018, you were 'exposed' to uranium by OSHA's definition," Stephenson wrote. "The radiation readings, at first blush, exceeds (sic) the Nuclear Regulatory Commission's safe limits. [...] Identifying who was exposed, and your exposure level, gets tricky and is our next important task." Stephenson said he had repeatedly asked National Park executives to inform the public, but never got a response.
"According to Stephenson, the uranium specimens had been in a basement at park headquarters for decades and were moved to the museum building when it opened, around 2000," reports AZCentral. "One of the buckets was so full that its lid would not close. Stephenson said the containers were stored next to a taxidermy exhibit, where children on tours sometimes stopped for presentations, sitting next to uranium for 30 minutes or more. By his calculation, those children could have received radiation dosages in excess of federal safety standards within three seconds, and adults could have suffered dangerous exposure in less than a half-minute."

The founder of Huawei has said there is "no way the US can crush" the company, in an interview with the BBC. From the report: Ren Zhengfei, founder and president of Huawei, described the arrest of his daughter Meng Wanzhou, the company's chief financial officer, as politically motivated. The US is pursuing criminal charges against Huawei and Ms Meng, including money laundering, bank fraud and stealing trade secrets. Huawei denies any wrongdoing.
Mr Ren spoke to the BBC's Karishma Vaswani in his first international broadcast interview since Ms Meng was arrested -- and dismissed the pressure from the US. "There's no way the US can crush us," he said. "The world cannot leave us because we are more advanced. Even if they persuade more countries not to use us temporarily, we can always scale things down a bit." However, he acknowledged that the potential loss of custom could have a significant impact. [...] Mr Ren warned that "the world cannot leave us because we are more advanced". "If the lights go out in the West, the East will still shine. And if the North goes dark, there is still the South. America doesn't represent the world. America only represents a portion of the world."

One of Windows Subsystem for Linux's more annoying tricks is it's hard to get at your Linux files from Windows. From a report: Oh, you can do it, but you take a real chance of ruining the files. To quote Microsoft, "DO NOT, under ANY circumstances, access, create, and/or modify files in your distro's filesystem using Windows apps, tools, scripts, consoles, etc." In the forthcoming Windows 10 April 2019 Update, aka Windows 10 19H1, this Linux file problem will finally be fixed. According to Craig Loewen, a Microsoft programming manger working on Windows Subsystem for Linux (WSL), "The next Windows update is coming soon and we're bringing exciting new updates to WSL with it! These include accessing the Linux file system from Windows, and improvements to how you manage and configure your distros in the command line."

President Donald Trump signed a directive on Tuesday that ordered the Department of Defense to create a Space Force as a sixth military branch. From a report: With a directive signed Tuesday, Mr. Trump was positioning the Space Force much as the Marine Corps fits into the Navy, officials said, with the result being lower costs and less bureaucracy. The plan would require congressional approval. Mr. Trump is to propose funding in his proposed 2020 budget, and spell out a goal of eventually establishing the Space Force as a separate military department, a senior administration official said. "Space, that's the next step and we have to be prepared," said Mr. Trump, who added that adversaries were training forces and developing technology. "I think we'll have great support from Congress."
The order Mr. Trump signed, Space Policy Directive 4, calls for a legislative proposal by the secretary of defense to establish a chief of staff of the Space Force within the Air Force. That officer would be a member of the Joint Chiefs of Staff, according to an outline. There also be a new under secretary of defense for space to be appointed by the president. The proposal calls for the Space Force to organize, train and equip personnel to defend the U.S. in space, to provide independent military options for "joint and national leadership" and "enable the lethality and effectiveness of the joint force," according to the administration's outline.

AmiMoJo shares a report: The founder of one of the first big companies to switch to a four-day working week has called on others to follow, claiming it has resulted in a 20% increase in productivity, appeared to have helped increase profits and boosted staff wellbeing. Analysis of one of the biggest trials yet of the four-day working week has revealed no fall in output, reduced stress and increased staff engagement, fuelling hopes that a better work-life-balance for millions could be in sight. Perpetual Guardian, a New Zealand financial services company, switched its 240 staff from a five-day to a four-day week last November and maintained their pay. Productivity increased in the four days they worked so there was no drop in the total amount of work done, a study of the trial released on Tuesday has revealed.
The trial was monitored by academics at the University of Auckland and Auckland University of Technology. Among the Perpetual Guardian staff they found scores given by workers about leadership, stimulation, empowerment and commitment all increased compared with a 2017 survey. Details of an earlier trial showed the biggest increases were in commitment and empowerment. Staff stress levels were down from 45% to 38%. Work-life balance scores increased from 54% to 78%. "This is an idea whose time has come," said Andrew Barnes, Perpetual Guardian's founder and chief executive. "We need to get more companies to give it a go. They will be surprised at the improvement in their company, their staff and in their wider community."
