Magazine For Museums Publishes Its 2040 Issue -- 23 Years Early (aam-us.org) 40

A nonprofit founded in 1906 is now offering a glimpse at 2040, according to an anonymous reader: The Alliance of American Museums has just published an ambitious Nov/Dec 2040 issue of Museum, the Alliance's magazine. The columns, reviews, articles, awards, and even the ads describe activities from a 2040 perspective, based on a multi-faceted consensus scenario.
Besides virtual reality centers (and carbon-neutral cities), it envisions de-extinction biologists who resurrect lost species. It also predicts a 2040 with orbiting storehouses to preserve historic artifacts (as well as genetic materials) as part of a collaboration with both NASA and a new American military branch called the US Space Corps. And of course, by 2040 musuems have transformed into hybrid institutions like "museum schools" and "well-being and cognitive health centers" that are both run by museums.

It also predicts for-profit museums that have partnered with corporations.

H1-B Administrators Are Challenging An Unusually Large Number of Applications (bloomberg.com) 304

Long-time Slashdot reader decaffeinated quotes Bloomberg: Starting this summer, employers began noticing that U.S. Citizenship and Immigration Services was challenging an unusually large number of H-1B applications. Cases that would have sailed through the approval process in earlier years ground to a halt under requests for new paperwork. The number of challenges -- officially known as "requests for evidence" or RFEs -- are up 44 percent compared to last year, according to statistics from USCIS...

"We're entering a new era," said Emily Neumann, an immigration lawyer in Houston who has been practicing for 12 years. "There's a lot more questioning, it's very burdensome." She said in past years she's counted on 90 percent of her petitions being approved by Oct. 1 in years past. This year, only 20 percent of the applications have been processed. Neumann predicts she'll still have many unresolved cases by the time next year's lottery happens in April 2018.

One Bitcoin Transaction Now Uses As Much Energy As Your House In a Week (vice.com) 227

Long-time Slashdot reader SlaveToTheGrind quotes Motherboard: Bitcoin's incredible price run to break over $7,000 this year has sent its overall electricity consumption soaring, as people worldwide bring more energy-hungry computers online to mine the digital currency. An index from cryptocurrency analyst Alex de Vries, aka Digiconomist, estimates that with prices the way they are now, it would be profitable for Bitcoin miners to burn through over 24 terawatt-hours of electricity annually as they compete to solve increasingly difficult cryptographic puzzles to "mine" more Bitcoins. That's about as much as Nigeria, a country of 186 million people, uses in a year.

This averages out to a shocking 215 kilowatt-hours (KWh) of juice used by miners for each Bitcoin transaction (there are currently about 300,000 transactions per day). Since the average American household consumes 901 KWh per month, each Bitcoin transfer represents enough energy to run a comfortable house, and everything in it, for nearly a week.

How Two Scientists Accurately Predicted Global Warming in 1967 (medium.com) 218

Slashdot reader Layzej shares an article from this spring marking the 50th anniversary of the first accurate climate model: Astrophysicist Ethan Siegel looks at a climate model (MW67) published in 1967 and finds "50 years after their groundbreaking 1967 paper, the science can be robustly evaluated, and they got almost everything exactly right."

An analysis on the "Climate Graphs" blog shows exactly how close the prediction has proven to be: "The slope of the CO2-vs-temperature regression line in the 50 years of actual observations is 2.57, only slightly higher than MW67's prediction of 2.36" They also note that "This is even more impressive when one considers that at the time MW67 was published, there had been no detectable warming in over two decades. Their predicted warming appeared to mark a radical change with the recent past:"

The Computer Scientist Who Prefers Voting With Paper (theatlantic.com) 219

Geoffrey.landis writes: The Atlantic profiles a computer scientist: Barbara Simons, who has been on the forefront of the pushback against electronic voting as a technology susceptible to fraud and hacking. When she first started writing articles about the dangers of electronic voting with no paper trail, the idea that software could be manipulated to rig elections was considered a fringe preoccupation; but Russia's efforts to influence the 2016 presidential election have reversed Simons's fortunes. According to the Department of Homeland Security, those efforts included attempts to meddle with the electoral process in 21 states; while a series of highly publicized hacks -- at Sony, Equifax, the U.S. Office of Personnel Management -- has driven home the reality that very few computerized systems are truly secure. Simons is a former President of the Association for Computing Machinery (ACM); and the group she helps run, Verified Voting, has been active in educating the public about the dangers of unverified voting since 2003.

NASA Discovers Mantle Plume That's Melting Antarctica From Below (newsweek.com) 244

schwit1 shares a report from Newsweek: Researchers at NASA have discovered a huge upwelling of hot rock under Marie Byrd Land, which lies between the Ross Ice Shelf and the Ross Sea, is creating vast lakes and rivers under the ice sheet. The presence of a huge mantle plume could explain why the region is so unstable today, and why it collapsed so quickly at the end of the last Ice Age, 11,000 years ago. Mantle plumes are thought to be part of the plumbing systems that brings hot material up from Earth's interior. Once it gets through the mantle, it spreads out under the crust, providing magma for volcanic eruptions. The area above a plume is known as a hotspot.

[I]n a study published in the Journal of Geophysical Research: Solid Earth, Seroussi and colleagues looked at one of the most well studied magma plumes on Earth -- the Yellowstone hotspot. The team developed a mantle plume model to look at how much geothermal heat would be needed to explain what is seen at Marie Byrd Land. They then used the Ice Sheet System Model (ISSM), which shows the physics of ice sheets, to look at the natural sources of heating and heat transport. This model enabled researchers to place "powerful constraint" on how much melt rate was allowable, meaning they could test out different scenarios of how much heat was being produced deep beneath the ice. Their findings showed that generally, the energy being generated by the mantle plume is no more than 150 milliwatts per square meter -- any more would result in too much melting. The heat generated under Yellowstone National Park, on average, is 200 milliwatts per square meter.
