Colors Help Set Body's Internal Clock 52

Posted by samzenpus from the sleepy-blue dept.
First time accepted submitter MakeItGlow writes A new study by researchers from the University of Manchester found that mice use the color of light to set their body clock. The researchers investigated whether color signals from the eyes wound up in the suprachiasmatic nucleus—the part of the brain in vertebrates that keeps time using electrical and chemical signals. From the article: "Scientists have long known about the role light plays in governing circadian rhythms, which synchronize life’s ebb and flow with the 24-hour day. But they weren’t sure how different properties of light, such as color and brightness, contributed to winding up that clock. 'As a sort of common sense notion people have assumed that the clock somehow measures the amount of light in the outside world,' says Tim Brown, a neuroscientist at the University of Manchester in the United Kingdom and an author of the new study. 'Our idea was that it might be doing something more sophisticated than that.'”

Pull-Top Can Tabs, At 50, Reach Historic Archaeological Status 120

Posted by timothy from the remember-making-giant-chains-of-these dept.
New submitter kuhnto writes A simple relic of 20th century life has taken on new meaning for archaeologists: The ring-tab beer can — first introduced 50 years ago — is now considered an historic-era artifact, a designation that bestows new significance on the old aluminum cans and their distinctive tabs that are still found across the country.

Oklahoma Says It Will Now Use Nitrogen Gas As Its Backup Method of Execution 591

Posted by timothy from the that's-not-the-only-cost dept.
schwit1 writes Yesterday, Oklahoma governor Mary Fallin signed into law a bill that approves the use of nitrogen gas for executions in the state. The method, which would effectively asphyxiate death row inmates by forcing them to breathe pure nitrogen through a gas mask, is meant to be the primary alternative to lethal injection, the Washington Post reports.

Fallin and other supporters of the procedure say it's pain-free and effective, noting that the nitrogen would render inmates unconscious within ten seconds and kill them in minutes. It's also cheap: state representatives say the method only requires a nitrogen tank and a gas mask, but financial analysts say its impossible to give precise figures, the Post reports.

Oklahoma's primary execution method is still lethal injection, but the state's procedure is currently under review by the Supreme Court. Earlier this week, Tennessee suspended executions statewide following challenges to its own lethal injection protocol.

Mandelbrot Zooms Now Surpass the Scale of the Observable Universe 157

Posted by timothy from the from-here-you-can-see-forever dept.
StartsWithABang writes You're used to real numbers: that is, numbers that can be expressed as a decimal, even if it's an arbitrarily long, non-repeating decimal. There are also complex numbers, which are numbers that have a real part and also an imaginary part. The imaginary part is just like the real part, but is also multiplied by i, or the square root of -1. It's a simple definition: the Mandelbrot set consists of every possible complex number, n, where the sequence n, n^2 + n, (n^2 + n)^2 + n, etc.—where each new term is the prior term, squared, plus n—does not go to either positive or negative infinity. The scale of zoom visualizations now goes well past the limits of the observable Universe, with no signs of loss of complexity at all.

John Gruber On Third-party Apple Watch Apps: They Suck and Are Really Slow 138

Posted by timothy from the tell-us-how-you-really-feel dept.
An anonymous reader writes During this week's episode of John Gruber's podcast, The Talk Show, Gruber sat down with Joanna Stern of the Wall Street Journal to talk all things Apple Watch. About two hours and 9 minutes into the podcast, both Gruber and Stern began lamenting the poor performance they saw with third-party Apple Watch apps. 'It makes me question whether there should be third party apps for it at all yet,' Gruber noted. The pair also took umbrage with what they perceived to be a poor design choice for the Apple Watch app screen, with both noting that the app icons were far too small to be practical.

Gyrocopter Pilot Appears In Court; Judge Bans Him From D.C. 271

Posted by timothy from the but-what-if-air-&-space-gets-the-copter? dept.
mpicpp writes The Florida mail carrier accused of landing a gyrocopter outside the U.S. Capitol on Wednesday was charged in federal court Thursday and has been barred from returning to the District of Columbia or flying any aircraft, officials said. Douglas Hughes, 61, was charged with violating aircraft registration requirements, a felony, and violating national defense airspace, a misdemeanor. If convicted, he could be sentenced to up to three years in prison for the felony and one year in prison for the airspace violation. U.S. Magistrate Judge Deborah A. Robinson also barred Hughes from the District of Columbia, except for court appearances, and said he must stay away from the Capitol, White House and nearby areas while he is there. He will also have to hand over his passport.

Microsoft's Role As Accuser In the Antitrust Suit Against Google 192

Posted by samzenpus from the on-the-other-side dept.
HughPickens.com writes Danny Hakim reports at the NYT that as European antitrust regulators formally accuse Google of abusing its dominance, Microsoft is relishing playing a behind-the-scenes role of scold instead of victim. Microsoft has founded or funded a cottage industry of splinter groups to go after Google. The most prominent, the Initiative for a Competitive Online Marketplace, or Icomp, has waged a relentless public relations campaign promoting grievances against Google. It conducted a study that suggested changes made by Google to appease regulators were largely window dressing. "Microsoft is doing its best to create problems for Google," says Manfred Weber, the chairman of the European People's Party, the center-right party that is the largest voting bloc in the European Parliament. "It's interesting. Ten years ago Microsoft was a big and strong company. Now they are the underdog."

According to Hakim, Microsoft and Google are the Cain and Abel of American technology, locked in the kind of struggle that often takes place when a new giant threatens an older one. Microsoft was frustrated after American regulators at the Federal Trade Commission didn't act on a similar antitrust investigation against Google in 2013, calling it a "missed opportunity." It has taken the fight to the state level, along with a number of other opponents of Google. Microsoft alleges that Google's anti-competitive practices include stopping Bing from indexing content on Google-owned YouTube; blocking Microsoft Windows smartphones from "operating properly" with YouTube; blocking access to content owned by book publishers; and limiting the flow of ad campaign information back to advertisers, making it more expensive to run ads with rivals. "Over the past year, a growing number of advertisers, publishers, and consumers have expressed to us their concerns about the search market in Europe," says Brad Smith, Microsoft's general counsel. "They've urged us to share our knowledge of the search market with competition officials."

Mystery "Warm Blob" In the Pacific Ocean Could Be Causing California's Drought 173

Posted by samzenpus from the it's-getting-hot-in-here dept.
Mr D from 63 writes A mysterious "warm blob" in the Pacific Ocean could be the reason why US West coast states like California are experiencing their worst ever drought, a new study says. From the article: "Nick Bond, a climate scientist at the Joint Institute for the Study of the Atmosphere and Ocean at the University of Washington, began watching the blob a year and a half ago. 'In the fall of 2013 and early 2014, we started to notice a big, almost circular mass of water that just didn't cool off as much as it usually did, so by spring of 2014 it was warmer than we had ever seen it for that time of year,' Bond said in a news release about the studies appearing in Geophysical Research Letters."

Supernovae May Not Be Standard Candles; Is Dark Energy All Wrong? 199

Posted by Soulskill from the either-that-or-it-isn't dept.
StartsWithABang writes: The accelerated expansion of the Universe — and hence, dark energy — was discovered by taking the well-understood phenomenon of type Ia supernovae and measuring them out to great distances. The results indicated that they were fainter than expected, and hence more distant, and hence the Universe's expansion must be accelerating. But new results have just come out, showing that supernovae may not be standard after all. Does this mean dark energy may not be real, or that it may just be slightly weaker than we previously thought?

Microsoft Pushes For Public Education Funding While Avoiding State Taxes 173

Posted by Soulskill from the cognitive-dissonance-provides-shareholder-value dept.
theodp writes: After stressing how important the funding of Washington State education — particularly CS Ed — is to Microsoft, company general counsel Brad Smith encountered one of those awkward interview moments (audio at 28:25). GeekWire Radio: "So, would you ever consider ending that practice [ducking WA taxes by routing software licensing royalties through Nevada-based Microsoft Licensing, GP] in Nevada [to help improve WA education]?" Smith: "I think there are better ways for us to address the state's needs than that kind of step." Back in 2010, Smith, Steve Ballmer, and Microsoft Corporation joined forces to defeat Proposition I-1098, apparently deciding there were better ways to address the state's needs than a progressive income tax.

LG Split Screen Software Compromises System Security 187

Posted by Soulskill from the low-grade dept.
jones_supa writes: The Korean electronics company LG ships a split screen tool with their ultra wide displays. It allows users to slice the Windows desktop into multiple segments. However, installing the software seriously compromises security of the particular workstation. The developers required administrator access for the software, but apparently they hacked their way out. The installer silently disables User Account Control, and enables a policy to start all applications as Administrator. In the article there is also a video presentation of the setup procedure. It is safe to say that no one should be running this software in its current form.

BitTorrent Launches Beta of Torrent-Based Browser Project Maelstrom 35

Posted by timothy from the bits-and-pieces-from-all-over dept.
An anonymous reader writes BitTorrent today launched Project Maelstrom, the company's distributed browser, in beta. The company also released new tools on GitHub that let developers and publishers build content for the browser. Announced in December, Project Maelstrom, then just an invite-only alpha, was described as "the first torrent-based browser." The launch today is an open beta, meaning anyone can now try an early version of Maelstrom. You do, however, need a Windows computer. Windows users can download the beta now from here. Since the alpha, BitTorrent says it has improved stability, integrated support for automatic updates, and added DHT visualization for users when loading torrents.

Florida Teen Charged With Felony Hacking For Changing Desktop Wallpaper 629

Posted by Soulskill from the climate-of-fear dept.
colinneagle writes: A 14-year-old middle school student in Holiday, Florida, was arrested this week and charged with "an offense against a computer system and unauthorized access," which is a felony. The student reportedly used an administrator password to log into a teacher's computer and change the background image to a photo of two men kissing.

The student also revealed his secrets after he was caught – the password was the teacher's last name, and the teacher had typed it in in full view of the students. The student said many other students used these administrators' passwords (their teachers' last names) so they can screen-share and video chat with other students. The student was briefly held in a nearby detention center, and the county Sheriff warned that other teenagers caught doing the same thing will "face the same consequences."

The Last Time Oceans Got This Acidic This Fast, 96% of Marine Life Went Extinct 417

Posted by Soulskill from the it's-not-easy-being-green dept.
merbs writes: The biggest extinction event in planetary history was driven by the rapid acidification of our oceans, a new study concludes (abstract). So much carbon was released into the atmosphere, and the oceans absorbed so much of it so quickly, that marine life simply died off, from the bottom of the food chain up. That doesn't bode well for the present, given the similarly disturbing rate that our seas are acidifying right now. A team led by University of Edinburgh researchers collected rocks in the United Arab Emirates that were on the seafloor hundreds of millions of years ago, and used the boron isotopes found within to model the changing levels of acidification in our prehistoric oceans. They now believe that a series of gigantic volcanic eruptions in the Siberian Trap spewed a great fountain of carbon into the atmosphere over a period of tens of thousands of years. This was the first phase of the extinction event, in which terrestrial life began to die out.

10 Years of Git: An Interview With Linus Torvalds 203

Posted by samzenpus from the straight-from-the-horses-mouth dept.
LibbyMC writes Git will celebrate its 10-year anniversary tomorrow. To celebrate this milestone, Linus shares the behind-the-scenes story of Git and tells us what he thinks of the project and its impact on software development. From the article: "Ten years ago this week, the Linux kernel community faced a daunting challenge: They could no longer use their revision control system BitKeeper and no other Software Configuration Management (SCMs) met their needs for a distributed system. Linus Torvalds, the creator of Linux, took the challenge into his own hands and disappeared over the weekend to emerge the following week with Git. Today Git is used for thousands of projects and has ushered in a new level of social coding among programmers."
