Cause of Global Warming 'Hiatus' Found Deep In the Atlantic

Posted by samzenpus
from the biggest-heatsink dept.
vinces99 writes with news about a study that may account for a slowdown in air temperature rises. Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth's surface. More than a dozen theories have now been proposed for the so-called global warming hiatus, ranging from air pollution to volcanoes to sunspots. New research from the University of Washington shows the heat absent from the surface is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle. The study is published in Science. Subsurface ocean warming explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at the Earth's surface. "Every week there's a new explanation of the hiatus," said corresponding author Ka-Kit Tung, a UW professor of applied mathematics and adjunct faculty member in atmospheric sciences. "Many of the earlier papers had necessarily focused on symptoms at the surface of the Earth, where we see many different and related phenomena. We looked at observations in the ocean to try to find the underlying cause." What they found is that a slow-moving current in the Atlantic, which carries heat between the two poles, sped up earlier this century to draw heat down almost a mile (1,500 meters). Most previous studies focused on shorter-term variability or particles that could block incoming sunlight, but they could not explain the massive amount of heat missing for more than a decade.

Zothecula writes We've been hearing a lot about the development of tiny flying sensor-equipped robots, that could be sent into areas such as disaster sites to seek out survivors or survey the damage. However, why go to the trouble of designing those robots from scratch, when there are already ready-made insects that are about the right size? That's the thinking behind research being conducted at North Carolina State University, which is aimed at converting moths into "biobots".

How Does Tesla Build a Supercharger Charging Site? 46

Posted by samzenpus
from the power-up dept.
cartechboy writes Tesla's Superchargers are the talk of the electric car community. These charging stations can take a Model S battery pack from nearly empty to about 150 miles of range in around 30 minutes. That's crazy fast, and it's nothing short of impressive. But what does it take to actually build a Tesla Supercharger site? Apparently a lot of digging. A massive trench is created to run high-capacity electric cables before the charging stations themselves are even installed. A diagram and photos of the Electric Conduit Construction build out have surfaced on the Internet. The conduits connect the charging stations to a power distribution center, which in turn is connected to a transformer that provides the power for charging cars. It took 11 days to install the six charging stalls in Goodland, Kansas. If you thought it was a quick process to build a Supercharger station, you were clearly wrong.

tlhIngan writes Municipal broadband is in the news again — this time Chief of Staff Matthew Berry, speaking at the National Conference of State Legislatures, has endorsed states' right to ban municipal broadband networks and warned the (Democrat-led) FCC to not do anything that a future Republican led FCC would dislike. The argument is that municipal broadband discourages private investment in broadband communications, that taxpayer-funded projects are barriers to future infrastructure investment.

Latest Wikipedia Uproar Over 'Superprotection' 78

metasonix writes: As if the problems brought up during the recent 2014 Wikimania conference weren't enough, now Wikipedia is having an outright battle between its editor and administrator communities, especially on the German-language Wikipedia. The Wikimedia Foundation, currently flush with cash from its donors, keeps trying to force flawed new software systems onto the editor community, who has repeatedly responded by disabling the software. This time, however, Foundation Deputy Director Erik Moeller had the bright idea to create a new level of page protection to prevent the new software from being disabled. "Superprotection" has resulted in an outright revolt on the German Wikipedia. There has been subsequent coverage in the German press, and people have issued demands that Moeller, one of Wikipedia's oldest insiders, be removed from his job. One English Wikipedia insider started a change.org petition demanding the removal of superprotection."

Future Hack: New Cybersecurity Tool Predicts Breaches Before They Happen 19

An anonymous reader writes: A new research paper (PDF) outlines security software that scans and scrapes web sites (past and present) to identify patterms leading up to a security breach. It then accurately predicts what websites will be hacked in the future. The tool has an accuracy of up to 66%. Quoting: "The algorithm is designed to automatically detect whether a Web server is likely to become malicious in the future by analyzing a wide array of the site's characteristics: For example, what software does the server run? What keywords are present? How are the Web pages structured? If your website has a whole lot in common with another website that ended up hacked, the classifier will predict a gloomy future. The classifier itself always updates and evolves, the researchers wrote. It can 'quickly adapt to emerging threats.'"

NASA's Space Launch System Searches For a Mission 32

schwit1 writes: Managers of NASA's Space Launch System (SLS) are searching for a mission that they can propose and convince Congress to fund. "Once SLS is into the 2020s, the launch rate should see the rocket launching at least once per year, ramping up to a projected three times per year for the eventual Mars missions. However, the latter won’t be until the 2030s. With no missions manifested past the EM-2 flight, the undesirable question of just how 'slow' a launch rate would be viable for SLS and her workforce has now been asked." Meanwhile, two more Russian rocket engines were delivered yesterday, the first time that's happened since a Russian official threatened to cut off the supply. Another shipment of three engines is expected later this year. In Europe, Arianespace and the European Space Agency signed a contract today for the Ariane 5 rocket to launch 12 more of Europe’s Galileo GPS satellites on three launches. This situation really reminds me of the U.S. launch market in the 1990s, when Boeing and Lockheed Martin decided that, rather than compete with Russia and ESA for the launch market, they instead decided to rely entirely on U.S. government contracts, since those contracts didn’t really demand that they reduce their costs significantly to compete.

New Research Suggests Cancer May Be an Intrinsic Property of Cells 121

Posted by Soulskill
from the kill-all-the-cells!-oh-wait dept.
cranky_chemist sends this report from NPR: "Cancer simply may be here to stay. Researchers at Kiel University, the Catholic University of Croatia and other institutions discovered that hydra — tiny, coral-like polyps that emerged hundreds of millions of years ago — form tumors similar to those found in humans. Which suggests that our cells' ability to develop cancer is "an intrinsic property" that has evolved at least since then — way, way, way before we rallied our forces to try to tackle it, said Thomas Bosch, an evolutionary biologist at Kiel University who led the study, published in Nature Communications in June (abstract) To get ahead of cancer, he said, "you have to interfere with fundamental pathways. It's a web of interactions," he said. "It's very difficult to do." That's why cancer "will probably never be completely eradicated."

Microsoft Lobby Denies the State of Chile Access To Free Software 95

walterbyrd writes: Fresh on the heels of the entire Munich and Linux debacle, another story involving Microsoft and free software has popped up across the world, in Chile. A prolific magazine from the South American country says that the powerful Microsoft lobby managed to turn around a law that would allow the authorities to use free software. "An independent member of the Chilean Parliament, Vlado Mirosevic, pushed a bill that would allow the state to consider free software when the authorities needed to purchase or renew licenses. ... A while later, the same member of the Parliament, Daniel Farcas, proposed another bill that actually nullified the effects of the previous one that had just been adopted. To make things even more interesting, some of the people who voted in favor of the first law also voted in favor of the second one. ... The new bill is even more egregious, because it aggressively pushes for the adoption of proprietary software. Companies that choose to use proprietary software will receive certain tax breaks, which makes it very hard for free software to get adopted."

Book Review: Social Engineering In IT Security Tools, Tactics, and Techniques 33

Posted by samzenpus
from the read-all-about-it dept.
benrothke writes When I got a copy of Social Engineering in IT Security Tools, Tactics, and Techniques by Sharon Conheady, my first thought was that it likely could not have much that Christopher Hadnagy didn't already detail in the definitive text on the topic: Social Engineering: The Art of Human Hacking. Obviously Hadnagy thought differently, as he wrote the forward to the book; which he found to be a valuable resource. While there is overlap between the two books; Hadnagy's book takes a somewhat more aggressive tool-based approach, while Conheady take a somewhat more passive, purely social approach to the topic. There are many more software tools in Hadnagy; while Conheady doesn't reference software tools until nearly half-way through the book. This book provides an extensive introduction to the topic and details how social engineering has evolved through the centuries. Conheady writes how the overall tactics and goals have stayed the same; while the tools and techniques have been modified to suit the times. Keep reading for the rest of Ben's review.

How Game Developers Turn Kickstarter Failure Into Success 23

Posted by Soulskill
from the pay-me-to-overpromise dept.
Nerval's Lobster writes When you ask random strangers on the Internet to give you money, there are no guarantees. That's true in almost any scenario, including when video game developers use Kickstarter to crowdfund the creation of a game. While 3,900 or so games have been funded on Kickstarter, more than 7,200 game projects failed to hit their goal. Within those two numbers are some people who fall into both categories: developers who failed to get funding on their first try, but re-launched campaigns and hit their goals. Jon Brodkin spoke with a handful of those indie game developers who succeeded on their second try; many of them used the momentum (and fans) from the first attempt to get a head start on funding the second, and one even adjusted his entire plan based on community feedback. But succeeding the second time also depended on quite a bit of luck.

Metamaterial Superconductor Hints At New Era of High Temperature Superconductors 32

Posted by Soulskill

KentuckyFC writes: Superconductors allow current to flow with zero resistance when cooled below some critical temperature. They are the crucial ingredients in everything from high-power magnets and MRI machines to highly sensitive magnetometers and magnetic levitation devices. But one big problem is that superconductors work only at very low temperatures — the highest is around 150 kelvin (-120 degrees centigrade). So scientists would dearly love to find ways of raising this critical temperature. Now a group of physicists say they've found a promising approach: to build metamaterial superconductors that steer electrons in the same way as other metamaterials steer light to create invisibility cloaks. The inspiration for the work comes from the observation that some high temperature superconductors consist of repeated layers of conducting and dielectric structures. So the team mixed tin — a superconductor at 3.7 kelvin — with the dielectric barium titanate and found that it raised the critical temperature by 0.15 kelvin. That's the first demonstration that superconductors can be thought of as metamaterials. With this proof of principle under their belts, the next step is to look for bigger gains at higher temperatures.

Experimental Drug Stops Ebola-like Infection 47

from the side-effects-may-include-spontaneous-combustion dept.
sciencehabit writes: An experimental treatment against an Ebola-related virus can protect monkeys even when given up to 3 days after infection, the point at which they show the first signs of disease. The virus, known as Marburg, causes severe hemorrhagic fever—vomiting, diarrhea, and internal bleeding. In one outbreak, it killed 90% of people it infected. There are no proven treatments or vaccines against it. The new results raise hopes that the treatment might be useful for human patients even if they don't receive it until well after infection. The company that makes the compound, Tekmira, based in Burnaby, Canada, has started a human safety trial of a related drug to treat Ebola virus disease, and researchers hope that it, too, might offer protection even after a patient has started to feel ill. In other Ebola news, the two American aid workers who were infected with the virus while in Liberia have now recovered and been released from the hospital.
