MAVEN Spies Mars' Atmosphere Leaching Out Into Space

SlashDot - Wed, 10/15/2014 - 1:15am
astroengine writes: Early results from NASA's recently arrived MAVEN Mars spacecraft show an extensive, tenuous cloud of hydrogen surrounding the red planet, the result of water breaking down in the atmosphere, scientists said Tuesday. MAVEN, an acronym for Mars Atmosphere and Volatile Evolution, arrived on Sept. 21 to help answer questions about what caused a planet that was once warm and wet to turn into the cold, dry desert that appears today. "It's measurements like these that will allow us to estimate the escape rate of hydrogen from the Martian atmosphere to space today. It's an important measurement to make because the hydrogen ... comes from water lower down in the atmosphere," MAVEN scientist Mike Chaffin, with the University of Colorado, Boulder, told reporters on a conference call.

Millions of Voiceprints Quietly Being Harvested

SlashDot - Tue, 10/14/2014 - 11:13pm
An anonymous reader sends this excerpt from The Guardian: Businesses and governments around the world increasingly are turning to voice biometrics, or voiceprints, to pay pensions, collect taxes, track criminals and replace passwords. "We sometimes call it the invisible biometric," said Mike Goldgof, an executive at Madrid-based AGNITiO, one of about 10 leading companies in the field. Those companies have helped enter more than 65M voiceprints into corporate and government databases, according to Associated Press interviews with dozens of industry representatives and records requests in the United States, Europe and elsewhere. ... The single largest implementation identified by the AP is in Turkey, where the mobile phone company Turkcell has taken the voice biometric data of some 10 million customers using technology provided by market leader Nuance Communications Inc. But government agencies are catching up.

"Double Irish" Tax Loophole Used By US Companies To Be Closed

SlashDot - Tue, 10/14/2014 - 9:03pm
An anonymous reader writes: The Irish Finance Minister announced on Tuesday that Ireland will no longer allow companies to register in Ireland unless the companies are also tax resident. This will effectively close off the corporate tax avoidance scheme known as the "Double Irish" used by the likes of Google, Apple, and Facebook to route their earnings through their Irish holdings in order to garner an effective tax rate of, as in Google FY2013, 0.16%. Ireland's new policy will take effect in 2015 for new companies. "For existing companies, there will be provision for a transition period until the end of 2020."

Google Finds Vulnerability In SSL 3.0 Web Encryption

SlashDot - Tue, 10/14/2014 - 7:04pm
AlbanX sends word that security researchers from Google have published details on a vulnerability in SSL 3.0 that can allow an attacker to calculate the plaintext of encrypted communications. Google's Bodo Moller writes, SSL 3.0 is nearly 15 years old, but support for it remains widespread. Most importantly, nearly all browsers support it and, in order to work around bugs in HTTPS servers, browsers will retry failed connections with older protocol versions, including SSL 3.0. Because a network attacker can cause connection failures, they can trigger the use of SSL 3.0 and then exploit this issue. Disabling SSL 3.0 support, or CBC-mode ciphers with SSL 3.0, is sufficient to mitigate this issue, but presents significant compatibility problems, even today. Therefore our recommended response (PDF) is to support TLS_FALLBACK_SCSV. This is a mechanism that solves the problems caused by retrying failed connections and thus prevents attackers from inducing browsers to use SSL 3.0. It also prevents downgrades from TLS 1.2 to 1.1 or 1.0 and so may help prevent future attacks.

Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

SlashDot - Tue, 10/14/2014 - 5:37pm
New submitter chaosdivine69 writes: According to Scientists at Nanyang Technology University (NTU), they have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes and have a 20-year lifespan (10,000 charges). The impact of this is potentially a game changer for a lot of industries reliant on lithium ion batteries. In the car industry, for example, consumers would save on costs for battery replacement and manufacturers would save on material construction (the researchers are using a nanotube structure of Titanium dioxide, which is an abundant, cheap, and safe material found in soil). Titanium dioxide is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays. It is believed that charging an electric car can be done in as little as 5 minutes, making it comparable to filling up a tank of gasoline.

How Women Became Gamers Through D&D

SlashDot - Tue, 10/14/2014 - 4:52pm
An anonymous reader writes: To add some historical context to the currently controversy surrounding attitudes toward women in gaming, Jon Peterson provides an in-depth historical look at the unsurprisingly male origins of the "gamer" identity. It also examines how Dungeons & Dragons helped to open the door for women in gaming — overturning a sixty-year-old dogma that was born when Wells's Little Wars first assumed the "disdain" of women for gaming.

Can the Sun Realistically Power Datacenters?

SlashDot - Tue, 10/14/2014 - 4:09pm
1sockchuck writes: A massive solar array in central New Jersey provides the daytime power for a server farm delivering online financial services for McGraw Hill. The 50-acre field of photovoltaic solar panels symbolizes a new phase in the use of renewable energy in data centers. Massive arrays can now provide tens of megawatts of solar power for companies (including Apple) that can afford the land and the expense. But some data center thought leaders argue that these huge fields are more about marketing than genuinely finding the best approach to a greener cloud.

Companies Genetically Engineer Spider Silk

SlashDot - Tue, 10/14/2014 - 3:27pm
gthuang88 writes: Spider silk is touted for its strength and potential to be used in body armor, sports gear, and even artificial tendons and implants. Now several companies including EntoGenetics, Kraig Labs, and Araknitek have developed genetic approaches to producing commercial quantities of the stuff. One method is to implant spider genes into silkworms, which then act as spider-silk factories. Another is to place the gene that encodes spider web production into the DNA of goats; these "spidergoats" then produce milk containing spider-silk proteins that can be extracted. There's still a long way to go, however, and big companies like DuPont and BASF have tried and failed to commercialize similar materials.

The Subtle Developer Exodus From the Mac App Store

SlashDot - Tue, 10/14/2014 - 2:43pm
An anonymous reader writes: Milen Dzhumerov, a software developer for OS X and iOS, has posted a concise breakdown of the problems with the Mac App Store. He says the lack of support for trial software and upgrades drives developers away by preventing them from making a living. Forced sandboxing kills many applications before they get started, and the review system isn't helpful to anyone. Dzhumerov says all of these factors, and Apple's unwillingness to address them, are leading to the slow but steady erosion of quality software in the Mac App Store. "The relationship between consumers and developers is symbiotic, one cannot exist without the other. If the Mac App Store is a hostile environment for developers, we are going to end up in a situation where, either software will not be supported anymore or even worse, won't be made at all. And the result is the same the other way around – if there are no consumers, businesses would go bankrupt and no software will be made. The Mac App Store can be work in ways that's beneficial to both developers and consumers alike, it doesn't have to be one or the other. If the MAS is harmful to either developers or consumers, in the long term, it will be inevitably harmful to both."

Confidence Shaken In Open Source Security Idealism

SlashDot - Tue, 10/14/2014 - 2:01pm
iONiUM writes: According to a few news articles, the general public has taken notice of all the recent security breaches in open source software. From the article: "Hackers have shaken the free-software movement that once symbolized the Web's idealism. Several high-profile attacks in recent months exploited security flaws found in the "open-source" software created by volunteers collaborating online, building off each other's work." While it's true that open source means you can review the actual code to ensure there's no data-theft, loggers, or glaring security holes, that idealism doesn't really help out most people who simply don't have time, or the knowledge, to do it. As such, the trust is left to the open source community, and is that really so different than leaving it to a corporation with closed source?"

ISPs Violating Net Neutrality To Block Encryption

SlashDot - Tue, 10/14/2014 - 11:52am
Dupple writes One of the most frequent refrains from the big broadband players and their friends who are fighting against net neutrality rules is that there's no evidence that ISPs have been abusing a lack of net neutrality rules in the past, so why would they start now? That does ignore multiple instances of violations in the past, but in combing through the comments submitted to the FCC concerning net neutrality, we came across one very interesting one that actually makes some rather stunning revelations about the ways in which ISPs are currently violating net neutrality/open internet principles in a way designed to block encryption and thus make everyone a lot less secure.

How English Beat German As the Language of Science

SlashDot - Tue, 10/14/2014 - 11:11am
HughPickens.com writes German was the dominant scientific language in 1900. Today if a scientist is going to coin a new term, it's most likely in English. And if they are going to publish a new discovery, it is most definitely in English. Look no further than the Nobel Prize awarded for physiology and medicine to Norwegian couple May-Britt and Edvard Moser. Their research was written and published in English. How did English come to dominate German in the realm of science? BBC reports that the major shock to the system was World War One, which had two major impacts. According to Gordin, after World War One, Belgian, French and British scientists organized a boycott of scientists from Germany and Austria. They were blocked from conferences and weren't able to publish in Western European journals. "Increasingly, you have two scientific communities, one German, which functions in the defeated [Central Powers] of Germany and Austria, and another that functions in Western Europe, which is mostly English and French," says Gordin. The second effect of World War One took place in the US. Starting in 1917 when the US entered the war, there was a wave of anti-German hysteria that swept the country. In Ohio, Wisconsin and Minnesota there were many, many German speakers. World War One changed all that. "German is criminalized in 23 states. You're not allowed to speak it in public, you're not allowed to use it in the radio, you're not allowed to teach it to a child under the age of 10," says Gordin. The Supreme Court overturned those anti-German laws in 1923, but for years they were the law of the land. What that effectively did, according to Gordin, was decimate foreign language learning in the US resulting in a generation of future scientists who came of age with limited exposure to foreign languages. That was also the moment, according to Gordin, when the American scientific establishment started to take over dominance in the world. "The story of the 20th Century is not so much the rise of English as the serial collapse of German as the up-and-coming language of scientific communication," concludes Gordin.

Flight Attendants Want Stricter Gadget Rules Reinstated

SlashDot - Tue, 10/14/2014 - 10:30am
stephendavion writes You might be super happy to toil away on your phone or tablet the entire time you're on a plane, but not everyone is pleased to see your face buried in your device during takeoff and landing. The Federal Aviation Administration's new, more relaxed rules on gadget use aren't sitting well with one group — flight attendants. According to a report from The Wall Street Journal, the nation's largest flight attendant union is now suing the FAA to have the ban on gadget use during takeoff and landing reinstated. The Association of Flight Attendants-CWA argues that the change has caused many passengers to ignore flight attendants' emergency announcements, and that the new rules violate federal regulations requiring passengers to stow all items during takeoff and landing.

Navy Tests Unpowered Exoskeleton

SlashDot - Tue, 10/14/2014 - 9:49am
gurps_npc (621217) writes "CNN has a very interesting article about an unpowered exoskeleton system called Fortis. Unlike the more famous TALOS system, this exoskeleton uses zero electricity, so it does not need batteries or an extension cord. Power requirements have always been the problem with powered exoskeletons, as batteries are heavy. The system is made out of lightweight aluminum and heavy tools connect directly to it. The weight of the tools is supported by the exoskeleton, so your arms, back and legs don't have to carry it. You only need to use muscle to move the tool, not simply carry it. The exoskeleton does not make you stronger. Instead it effectively increases your stamina by relieving fatigue caused by carrying the heavy tool.
