20-Year-Old Military Weather Satellite Explodes In Orbit 253

schwit1 writes A 20-year-old U.S. military weather satellite apparently exploded for no obvious reason. The incident has put several dozen pieces of space junk into orbit. From the article: "A 20-year-old military weather satellite apparently exploded in orbit Feb. 3 following what the U.S. Air Force described as a sudden temperature spike. The “catastrophic event” produced 43 pieces of space debris, according to Air Force Space Command, which disclosed the loss of the satellite Feb. 27 in response to questions from SpaceNews. The satellite, Defense Meteorological Satellite Program Flight 13, was the oldest continuously operational satellite in the DMSP weather constellation."

Physicists May Be One Step Closer To Explaining High-Temp Superconductivity 58

sciencehabit writes For years some physicists have been hoping to crack the mystery of high-temperature superconductivity—the ability of some complex materials to carry electricity without resistance at temperatures high above absolute zero—by simulating crystals with patterns of laser light and individual atoms. Now, a team has taken—almost—the next-to-last step in such 'optical lattice' simulation by reproducing the pattern of magnetism seen in high-temperature superconductors from which the resistance-free flow of electricity emerges.

Pharming Attack Targets Home Router DNS Settings 39

msm1267 (2804139) writes Pharming attacks are generally network-based intrusions where the ultimate goal is to redirect a victim's web traffic to a hacker-controlled webserver, usually through a malicious modification of DNS settings. Some of these attacks, however, are starting to move to the web and have their beginnings with a spam or phishing email. Proofpoint reported on the latest iteration of this attack, based in Brazil. The campaign was carried out during a five-week period starting in December when Proofpoint spotted phishing messages, fewer than 100, sent to customers of one of the country's largest telecommunications companies.

Research Suggests That Saunas Help You Live Longer 208

jones_supa writes A study of Finnish men suggests that frequent sauna baths may help you live longer. Previous research has suggested that saunas might improve blood vessel function and exercise capacity, or even lower blood pressure in patients with hypertension. The new study links long, hot sauna baths with more benefits, including fewer deaths from heart attacks, strokes, various heart-related conditions and other causes. The study tracked 2315 Finnish men for nearly 20 years on average. Most participants used saunas at least once weekly. Those who used them four to seven times weekly received the greatest benefits. The study published in JAMA Internal Medicine wraps up by saying that further studies are warranted to establish the potential mechanism that links sauna bathing and the aforementioned cardiovascular benefits.

42 Artificial Intelligences Are Going Head To Head In "Civilization V" 52

rossgneumann writes The r/Civ subreddit is currently hosting a fascinating "Battle Royale" in the strategy game Civilization V, pitting 42 of the game's built-in, computer-controlled players against each other for world domination. The match is being played on the largest Earth-shaped map the game is capable of, with both civilizations that were included in the retail version of the game and custom, player-created civilizations that were modded into it after release.

Xfce 4.12 Released 91

motang writes: After two years of hard work (and much to the dismay of naysayers who worried the project has been abandoned), the Xfce team has announced the release of Xfce 4.12. Highlights include improvements to the window switcher dialog, intelligent hiding of the panel, new wallpaper settings, better multi-monitor support, improved power settings, additions to the file manager, and a revamped task manager. Here is a quick tour, the full changelog, and the download page. I have been running it since Xubuntu 15.04 beta 1 was released two days ago. It is much improved over 4.10, and the new additions are great.

Under US Pressure, PayPal Stops Working With Mega 136

New submitter seoras sends news that PayPal is now refusing to handle payments for Mega, Kim Dotcom's cloud storage service. A report (PDF) issued in September of last year claimed Mega and other "cyberlocker" sites made a great deal of illicit money off piracy. Mega disputes this, of course, and says the report caused U.S. Senator Patrick Leahy to pressure credit card companies to stop working with Mega. Those companies then pressured PayPal to stop as well. The hosting company claims, "MEGA provided extensive statistics and other evidence showing that MEGA’s business is legitimate and legally compliant. After discussions that appeared to satisfy PayPal’s queries, MEGA authorised PayPal to share that material with Visa and MasterCard. Eventually PayPal made a non-negotiable decision to immediately terminate services to MEGA."

Blu-Ray Players Hackable Via Malicious Discs 107

An anonymous reader writes: Some Blu-Ray disc interactive features use a Java variant for UIs and applications. Stephen Tomkinson just posted a blog discussing how specially created Blu-Ray discs can be used to hack various players using exploits related to their Java usage. He hacked one Linux-based, network-connected player to get root access through vulnerabilities introduced by the vendor. He did the same thing against Windows Blu-Ray player software. Tomkinson was then able to combine both, along with detection techniques, into a single disc.

Mysterious Siberian Crater Is Just One of Many 88

New submitter Sardaukar86 sends this excerpt from a Washington Post report: In the middle of last summer came news of a bizarre occurrence no one could explain. Seemingly out of nowhere, a massive crater appeared in one of the planet's most inhospitable lands. Early estimates said the crater, nestled in a land called "the ends of the Earth" where temperatures can sink far below zero, yawned nearly 100 feet in diameter. The saga deepened. The Siberian crater wasn't alone. There were two more, ratcheting up the tension in a drama that hit its climax as a probable explanation surfaced. Global warming had thawed the permafrost, which had caused methane trapped inside the icy ground to explode.

Now, however, researchers fear there are more craters than anyone knew — and the repercussions could be huge. Russian scientists have now spotted a total of seven craters, five of which are in the Yamal Peninsula. Two of those holes have since turned into lakes. And one giant crater is rimmed by a ring of at least 20 mini-craters, the Siberian Times reported.

Ask Slashdot: Whiteboard Substitutes For Distributed Teams? 164

DoofusOfDeath writes I work on a fully distributed software development team with 5-10 people. Normally it's great, but when we're doing heavy design work, we really need to all be standing in front of a whiteboard together. This is expensive and time consuming, because it involves airplanes and hotels. Conference calls, editing shared Google docs, etc. just don't seem to be the same. Have people found any good tools or practices to replace standing in front of a real whiteboard?

Methane-Based Life Possible On Titan 69

Randym writes: With the simultaneous announcement of a possible nitrogen-based, cell-like structure allowing life outside the "liquid water zone" (but within a methane atmosphere) announced by researchers at Cornell (academic paper) and the mystery of fluctuating methane levels on Mars raising the possibility of methane-respiring life, there now exists the possibility of a whole new branch of the tree of life that does not rely on either carbon or oxygen for respiration. We may find evidence of such life here on Earth down in the mantle where "traditional" life cannot survive, but where bacteria has evolved to live off hydrocarbons like methane and benzene.

NSA Spying Wins Another Rubber Stamp 87

schwit1 sends this report from the National Journal: A federal court has again renewed an order allowing the National Security Agency to continue its bulk collection of Americans' phone records, a decision that comes more than a year after President Obama pledged to end the controversial program. The Foreign Intelligence Surveillance Court approved this week a government request to keep the NSA's mass surveillance of U.S. phone metadata operating until June 1, coinciding with when the legal authority for the program is set to expire in Congress. The extension is the fifth of its kind since Obama said he would effectively end the Snowden-exposed program as it currently exists during a major policy speech in January 2014. Obama and senior administration officials have repeatedly insisted that they will not act alone to end the program without Congress.

Hyperloop Testing Starts Next Year 157

neanderslob writes: In 2013, Elon Musk told us about a theoretical transportation system he'd been thinking about for a while. It was called "hyperloop," and it was a tube-based system capable of sending people and things at speeds of up to 800mph. Now, a company called Hyperloop Transportation Technologies plans to start construction on an actual hyperloop next year. The idea is to build it to serve Quay Valley (a proposed 75,000-resident solar power city in Kings County, California). The project will be paid for with $100 million the company expects to raise through a direct public offering in the third quarter of this year. The track itself will be a 5-mile loop and won't reach anywhere close to the 800mph Musk proposed in his white paper — but it's a start.

Is That Dress White and Gold Or Blue and Black? 420

HughPickens.com writes Color scientists already have a word for it: Dressgate. Now the Washington Post reports that a puzzling thing happened on Thursday night consuming millions — perhaps tens of millions — across the planet and trending on Twitter ahead of even Jihadi John's identification. The problem was this: Roughly three-fourths of people swore that this dress was white and gold, according to BuzzFeed polling but everyone else said it's dress was blue. Others said the dress could actually change colors. So what's going on? According to the NYT our eyes are able to assign fixed colors to objects under widely different lighting conditions. This ability is called color constancy. But the photograph doesn't give many clues about the ambient light in the room. Is the background bright and the dress in shadow? Or is the whole room bright and all the colors are washed out? If you think the dress is in shadow, your brain may remove the blue cast and perceive the dress as being white and gold. If you think the dress is being washed out by bright light, your brain may perceive the dress as a darker blue and black.

According to Beau Lotto, the brain is doing something remarkable and that's why people are so fascinated by this dress. "It's entertaining two realities that are mutually exclusive. It's seeing one reality, but knowing there's another reality. So you're becoming an observer of yourself. You're having tremendous insight into what it is to be human. And that's the basis of imagination." As usual xkcd has the final word.
