An anonymous reader shares a report: The missing links between galaxies have finally been found. This is the first detection of the roughly half of the normal matter in our universe -- protons, neutrons and electrons -- unaccounted for by previous observations of stars, galaxies and other bright objects in space. You have probably heard about the hunt for dark matter, a mysterious substance thought to permeate the universe, the effects of which we can see through its gravitational pull. But our models of the universe also say there should be about twice as much ordinary matter out there, compared with what we have observed so far. Two separate teams found the missing matter -- made of particles called baryons rather than dark matter -- linking galaxies together through filaments of hot, diffuse gas. "The missing baryon problem is solved," says Hideki Tanimura at the Institute of Space Astrophysics in Orsay, France, leader of one of the groups. The other team was led by Anna de Graaff at the University of Edinburgh, UK. Because the gas is so tenuous and not quite hot enough for X-ray telescopes to pick up, nobody had been able to see it before.Read Replies (0)

Readers share a Motherboard article: There are seemingly two inescapable realities for big-budget filmmakers in 2017: you have to use existing intellectual property and you must provide spectacle that can lure massive domestic and foreign audiences to the the theater. It seemed that Denis Villeneuve chose wisely when he selected the IP that he would ride into the mainstream. [...] There is much to admire, but as a whole, Blade Runner 2049 works best as a case for why filmmakers like Villeneuve should be given big budgets to try out new concepts rather than retread what's come before them. Just like Arrival was at its best when we saw the elegance of how the space ship and the aliens within it actually functioned, this version of Blade Runner shines when we get to watch how Villeneuve's dystopia operates. Moments of technical brilliance small and large are at the soul of this film. Whether you're watching the creation of robot memories, the execution of an air strike from an effortless, detached distance, or even something as simple as a stroll through a hall of records, the mechanics of this world are jaw-dropping. Ryan Gosling (K) wisely opts for a muted, brooding performance, allowing the world to steal the show while still illustrating the burden of living in it. Even with all of this technical brilliance on display (the costumes, sound, and special effects are brilliant), the baggage of the original film's mythology weighs down Blade Runner 2049. The most burdensome baggage for Villeneuve to carry, sadly, is the Blade Runner story itself.Read Replies (0)

An anonymous shares a report: People who are miserable on Monday have lots of company. It's the worst day of the week for millions, according to researchers at the University of Vermont Complex Systems Center who analyze Twitter messages for happiness sentiment. Mood tends to improve during the rest of the week, peaking on Saturday, before beginning to crash again, according to data based tweets since 2008. In this analysis, the university's "hedonometer" takes a random sample of about 50 million Twitter posts each day, which is roughly 10% of all the site's message traffic. The researchers have assigned average scores to more than 10,000 commonly used words (from 1 to 9, on a scale of increasing happiness), which are used to measure a particular day's happiness. The data can also offer some insight into how populations have responded to major events. The day after the mass shooting in Las Vegas on Oct. 2 was Twitter's saddest day on record, according to the University of Vermont research. Another low was recorded on May 2, 2011, when Osama Bin Laden, the terrorist mastermind behind thousands of murders, was killed. Rather than clear positivity, language used on Twitter "reflected that a very negatively viewed character met a very negative end," according to the researcher's website.Read Replies (0)

Microsoft CEO Satya Nadella has just published a new book called Hit Refresh: The Quest to Rediscover Microsoft's Soul and Imagine a Better Future for Everyone. An anonymous reader quotes India Today:
Nadella's push for cultural shift -- and hiring "learn-it-alls" instead of "know-it-alls" -- is largely meant to jolt enthusiasm for a new era of innovation at the company. Microsoft had long depended on the success of its flagship Windows operating system and the royalties it gets for each PC sold with it. But the global PC market is declining, and Microsoft fell behind as Apple and Google led the shift to smartphones. Nadella doesn't take any shots at Microsoft's co-founder and first CEO Bill Gates -- who wrote the book's foreword -- or Ballmer. But he's frank about their disagreements, especially over Ballmer's disastrous $7.3 billion acquisition of Nokia's phone business in 2014.
Nadella also refers to the company's previous organizational structure as a "confederation of fiefdoms" and recounts negative feedback received from employee surveys and emails. "The company was sick," Nadella writes. "Employees were tired. They were frustrated. They were fed up with losing and falling behind despite their grand plans and great ideas. They came to Microsoft with big dreams, but it felt like all they really did was deal with upper management, execute taxing processes and bicker in meetings..." He promises not to squander the new energy felt by employees after years of frustration. So far, it seems to be paying off; Microsoft shares have doubled since he took the top job in early 2014, and the company is attracting buzz for its work in AI, augmented reality and a new effort in futuristic computing.
A former Microsoft board member says Nadella "has made people believe in the future of Microsoft in a way that neither Bill nor Steve really did."Read Replies (0)

An anonymous reader quote the Guardian:
Warming soil releases more carbon into the atmosphere than previously thought, suggesting a potentially disastrous feedback mechanism whereby increases in global temperatures will trigger massive new carbon releases in a cycle that may be impossible to break... The 26-year study is one of the biggest of its kind, and is a groundbreaking addition to our scant knowledge of exactly how warming will affect natural systems. Potential feedback loops, or tipping points, have long been suspected to exist by scientists, and there is some evidence for them in the geological record. What appears to happen is that once warming reaches a certain point, these natural biological factors kick in and can lead to a runaway, and potentially unstoppable, increase in warming...
In the Science study, researchers examined plots of soil in the Harvard Forest in Massachusetts, a mixed hardwood forest in the U.S. They experimented by heating some of the plots with underground cables to 5C above normal levels, leaving others as a control. The long-term study revealed that in the first 10 years there was a strong increase in the carbon released from the heated plots, then a period of about seven years when the carbon release abated. But after this second calmer period, which the scientists attribute to the adjustment of the soil microbes to the warmer conditions, the release of carbon resumed its upward path. From 1991, when the experiment began, the plots subjected to 5C warming lost about 17% of the carbon that had been stored in the top 60cm of the soil, where the greatest concentration of organic matter is to be found...

Before anyone cries "free speech must always be free," let me qualify the question. Under a myriad of different internet sites and blogs are these click-through adverts that promise quick "miracle cures" for everything from toenail fungus to hair loss to tinnitus to age-related skin wrinkles to cancer. A lot of the ads begin with copy that reads "This one weird trick cures....." Most of the "cures" on offer are complete and utter crap designed to lift a few dollars from the credit cards of hundreds of thousands of gullible internet users. The IQ boosting pills that supposedly give you "amazing mental focus after just 2 weeks" don't work at all. Neither do any of the anti-ageing or anti-wrinkle creams, regardless of which "miracle berry" extract they put in them this year. And if you try to cure your cancer with an Internet remedy rather than seeing a doctor, you may actually wind up dead.
So the question -- is peddling this stuff online really "free speech"? You are promising something grandiose in exchange for hard cash that you know doesn't deliver any benefits at all.
Long-time Slashdot reader apraetor counters, "But how do you determine what is 'true'?" And Slashdot reader ToTheStars argues "It's already established that making claims about medicine is subject to scrutiny by the FDA (or the relevant authority in your jurisdiction)." But are other things the equivalent of yelling "fire" in a crowded movie theatre? Leave your best thoughts in the comments. Is deliberately misleading people on the internet free speech?Read Replies (0)

"SiFive has declared that 2018 will be the year of RISC V Linux processors," writes Design News. An anonymous reader quotes their report:
When it released its first open-source system on a chip, the Freeform Everywhere 310, last year, Silicon Valley startup SiFive was aiming to push the RISC-V architecture to transform the hardware industry in the way that Linux transformed the software industry. Now the company has delivered further on that promise with the release of the U54-MC Coreplex, the first RISC-V-based chip that supports Linux, Unix, and FreeBSD... This latest development has RISC-V enthusiasts particularly excited because now it opens up a whole new world of use cases for the architecture and paves the way for RISC-V processors to compete with ARM cores and similar offerings in the enterprise and consumer space...
"The U54 Coreplexes are great for companies looking to build SoC's around RISC-V," Andrew Waterman co-founder and chief engineer at SiFive, as well as the one of the co-creators of RISC-V, told Design News. "The forthcoming silicon is going to enable much better software development for RISC-V." Waterman said that, while SiFive had developed low-level software such as compilers for RISC-V the company really hopes that the open-source community will be taking a much broader role going forward and really pushing the technology forward. "No matter how big of a role we would want to have we can't make a dent," Waterman said. "But what we can do is make sure the army of engineers out there are empowered."Read Replies (0)

"The White House and Equifax Agree: Social Security Numbers Should Go," reads a headline at Bloomberg. Securities lawyer Jerri-Lynn Scofield tears down one proposed alternative: a universal biometric identity system (possibly using fingerprints and an iris scan) with further numeric verification. Presto Vivace shared the article:
Using a biometric system when the basic problem of securing and safeguarding data have yet to be solved will only worsen, not address, the hacking problem. What we're being asked to do is to turn over our biometric information, and then trust those to whom we do so to safeguard that data. Given the current status of database security, corporate and governmental accountability, etc.: How do you think that is going to play out...?
[M]aybe we should rethink the whole impulse to centralize such data collection, for starters. And, after such a thought experiment, then further focus on obvious measures to safeguard such information -- such as installing regular software patches that could have prevented the Equifax hack -- should be the priority. And, how about bringing back a concept in rather short supply in C-suites -- that of accountability? Perhaps measures to increase that might be a better idea than gee whiz misdirected techno-wizardry... The Equifax hack has revealed the sad and sorry state of cybersecurity. But inviting the biometric ID fairy to drop by and replace the existing Social Security number is not the solution.
The article calls biometric identification systems "another source of data to be mined by corporations, and surveilled by those who want to do so. And it would ultimately not foil identity theft." It suggests currently biometric ids are a distraction from the push to change the credit bureau business model -- for example, requiring consumers to opt-in to the collection of their personal data.Read Replies (0)

53-year-old astronaut Scott Kelly shared a dramatic excerpt from his new book Endurance: A Year in Space, A Lifetime of Discovery in the Brisbane Times, describing his first 48 hours back on earth and what he'd learned on the mission:
I push back from the table and struggle to stand up, feeling like a very old man getting out of a recliner... I make it to my bedroom without incident and close the door behind me. Every part of my body hurts. All my joints and all of my muscles are protesting the crushing pressure of gravity. I'm also nauseated, though I haven't thrown up... When I'm finally vertical, the pain in my legs is awful, and on top of that pain I feel a sensation that's even more alarming: it feels as though all the blood in my body is rushing to my legs, like the sensation of the blood rushing to your head when you do a handstand, but in reverse. I can feel the tissue in my legs swelling... Normally if I woke up feeling like this, I would go to the emergency room. But no one at the hospital will have seen symptoms of having been in space for a year...
