In the face of an era of extreme weather brought on by climate change, global cities are working to improve their defenses. The New York Times reports (Warning: may be paywalled; alternative source) of Tokyo's $2 billion underground anti-flood system that consists of tunnels that divert water away from the region's most vulnerable floodplains. The city is "preparing for flooding beyond anything we've seen," says Kuniharu Abe, head of the underground site. From the report: But even in Tokyo, the onset of more frequent and intense storms has forced officials to question whether the region's protections are strong enough, a concern that has become more urgent as the city prepares to host the 2020 Olympic Games. Across Japan, rainfall measuring more than 2 inches an hour has increased 30 percent over the past three decades, the Japan Meteorological Agency estimates. The frequency of rainfall of more than 3 inches an hour has jumped 70 percent. The agency attributes the increase of these intense rains to global warming, heralding a new era in a country that is among the world's wettest, with a language that has dozens of words for rain. [...] Experts have also questioned the wisdom of erecting more concrete defenses in a country that has dammed most of its major river systems and fortified entire shorelines with breakwaters and concrete blocks. Some of these protections, they say, only encourage development in regions that could still be vulnerable to future flooding. In eastern Saitama, where the Kasukabe facility has done the most to reduce floods, local industry has flourished; the region has successfully attracted several large e-commerce distribution centers and a new shopping mall. Still, the Kasukabe operation remains a critical part of Tokyo's defenses, say officials at Japan's Land Ministry, which runs the site. Five vertical, underground cisterns, almost 250 feet deep, take in stormwater from four rivers north of Tokyo. A series of tunnels connect the cisterns to a vast tank, larger than a soccer field, with ceilings held up by 60-foot pillars that give the space a temple-like feel. From that tank, industrial pumps discharge the floodwater at a controlled pace into the Edo river, a larger river system that flushes the water into Tokyo Bay.Read Replies (0)

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...
