sciencehabit writes "Almost all organisms, from bacteria to mammals, have a circadian clock—a mechanism in their cells which keeps them in sync with Earth's day-and-night cycle. But many organisms follow other rhythms as well. Now, new research provides the first evidence that animals have molecular cycles independent of the circadian rhythm. They include a sea louse whose swimming patterns sync up with the tides, and a marine worm that matures and spawns in concert with the phases of the moon. The discoveries suggest that noncircadian clocks might be common and could explain a variety of biological rhythms."

Zothecula writes "Earlier this year, we heard about a gun and a fogging system, both of which tag criminals with synthesized DNA. The idea is that when those people are apprehended later, they can be linked to the crime by analyzing the location- or event-specific DNA still on their skin or clothing. Now, scientists at the Technology Transfer Unit of Portugal's University of Aveiro are developing something similar – 'DNA barcodes' that can be applied to products, then subsequently read as a means of identification."
Hugh Pickens DOT Com writes "Joseph Stromberg reports at the Smithsonian that if there's one group has an obvious and immediate financial stake in climate change, it's the insurance industry and in recent years, insurance industry researchers who attempt to determine the annual odds of catastrophic weather-related disasters say they're seeing something new. 'Our business depends on us being neutral. We simply try to make the best possible assessment of risk today, with no vested interest,' says Robert Muir-Wood, the chief scientist of Risk Management Solutions (RMS), a company that creates software models to allow insurance companies to calculate risk. Most insurers, including the reinsurance companies that bear much of the ultimate risk in the industry, have little time for the arguments heard in some right-wing circles that climate change isn't happening, and are quite comfortable with the scientific consensus that burning fossil fuels is the main culprit of global warming. 'Insurance is heavily dependent on scientific thought,' says Frank Nutter, president of the Reinsurance Association of America. 'It is not as amenable to politicized scientific thought.' A pronounced shift can be seen in extreme rainfall events, heat waves and wind storms and the underlying reason is climate change, says Muir-Wood, driven by rising greenhouse gas emissions. 'The first model in which we changed our perspective is on U.S. Atlantic hurricanes. Basically, after the 2004 and 2005 seasons, we determined that it was unsafe to simply assume that historical averages still applied,' he says. 'We've since seen that today's activity has changed in other particular areas as well—with extreme rainfall events, such as the recent flooding in Boulder, Colorado, and with heat waves in certain parts of the world.' Muir-Wood puts his money where his mouth is. 'I personally wouldn't invest in beachfront property anymore,' he says, noting the steady increase in sea level we're expecting to see worldwide in the coming century, on top of more extreme storms. 'And if you're thinking about it, I'd calculate quite carefully how far back you'd have to be in the event of a hurricane.'"
First time accepted submitter loftarasa writes "A group of scientists led by Harvard Professor of Physics Mikhail Lukin and MIT Professor of Physics Vladan Vuletic have developed a form of matter by binding massless photons together in a special kind of medium to create 'photonic molecules', effectively bringing us a bit closer to a world with lightsabers. 'The discovery, Lukin said, runs contrary to decades of accepted wisdom about the nature of light. Photons have long been described as massless particles which don't interact with each other – shine two laser beams at each other, he said, and they simply pass through one another. "Photonic molecules," however, behave less like traditional lasers and more like something you might find in science fiction – the light saber.' The work is described in Nature (paywalled)."
Lucas123 writes "After three years of work, German and French researchers have achieved a new world record on converting sunlight to energy through a photovoltaic cell, achieving a 44.7% rate of efficiency, which was measured at a concentration of 297 suns. The efficiency rating means the solar cell collects 44.7% of the sun's spectrum's energy, from ultraviolet to the infrared spectrum, which is converted into electrical energy. The team of researchers said the technology places them on the path to achieving their roadmap of 50% efficiency in solar energy conversion."
rjmarvin writes "Google search is turning 15, and on a media field trip to the Menlo Park garage where Sergey Brin and Larry Page began the company, they rolled out a slew of product updates. Chief among them was the announcement of a new search algorithm called Hummingbird along with an updated Knowledge Graph and other search improvements, on top of updated Google Now cards for Android, push notifications for Google's iOS app and more."
mask.of.sanity writes "Researchers are closing in on a means to detect previously undetectable stealthy malware that resides in peripherals like graphics and network cards. The malware was developed by the same researchers and targeted host runtime memory using direct memory access provided to hardware devices. They said the malware was a 'highly critical threat to system security and integrity' and could not be detected by any operating system."
PCWorld reports that "[A] U.S. surveillance court has given the National Security Agency no limit on the number of U.S. telephone records it collects in the name of fighting terrorism, the NSA director said Thursday. The NSA intends to collect all U.S. telephone records and put them in a searchable 'lock box' in the interest of national security, General Keith Alexander, the NSA's director, told U.S. senators." But don't worry; it's just metadata, until it isn't. (Your row in the NSA database may already be getting cozy in its nice new home in Utah.)
kthreadd writes "Version 3.10 of the GNOME software collection has been released. New in this release is improved support for Wayland, the upcoming X replacement. The system status menus have been consolidated into one single menu. Many of the applications in GNOME now features header bars instead of title bars, which merges the titlebar and toolbar into a single element and allows applications to offer more dynamic user interfaces. GNOME now also includes an application for searching, browsing and installing applications called Software. Several other new applications have also been added to GNOME including Music, Photos, Notes and Maps."
astroengine writes "By now, we probably all know that there was once significant quantities of water on the Martian surface and, although the red planet is bone dry by terrestrial standards, water persists as ice just below the surface to this day. Now, according to a series of new papers published in the journal Science, NASA's Mars Science Laboratory rover Curiosity has found that the Mars topsoil is laced with surprisingly high quantities of the wet stuff. And this could be good news for future Mars colonists. 'If you take a cubic foot of that soil you can basically get two pints of water out it — a couple of water bottles like you'd take to the gym, worth of water,' Curiosity scientist Laurie Leshin, of Rensselaer Polytechnic Institute, N.Y., told Discovery News."
CircuitCo started making something they called the BeagleBoard -- an open source hardware single-board computer for educators and experimenters. Now, with help and support from Intel, they're making and supporting the Atom-based MinnowBoard, which is also open source, and comes with Angstrom Linux to help experimenters get started with it. David Anders is the Senior Embedded Systems Engineer at CircuitCo. Slashdot's Timothy Lord met David at LinuxCon North America 2013 in New Orleans and made this video of him talking about the recently-released MinnowBoard and the more mature BeagleBoard.
An anonymous reader writes "Today the Federal Patent Court of Germany shot down an Apple photo gallery bounce-back patent over which Cupertino was/is suing Samsung and Motorola. A panel of five judges found the patent invalid because the relevant patent application was filed only in June 2007 but Steve Jobs already demoed the feature in January 2007 (video). While this wouldn't matter in the U.S., it's a reason for a patent to be invalidated in Europe. For different reasons someone thought the iPhone presentation was a mistake. It now turns out that when Steve Jobs said "Boy have we patented it!" his company forgot that public disclosure, even by an inventor, must not take place before a European patent application is filed. But Apple can still sue companies over the Android photo gallery: in addition to this patent it owns a utility model, a special German intellectual property right that has a shorter term (10 years) and a six-month grace period, which is just enough to make sure that history-making Steve Jobs video won't count as prior art."
New submitter ddyer writes "Java 1.7.0_40 [Note: released earlier this month] introduces a new 'red text' warning when running unsigned Java applets. 'Running unsigned applications like this will be blocked in a future release...' Or, for self-signed applets,'Running applications by UNKNOWN publishers will be blocked in a future release...' I think I see the point — this will give the powers that be the capability to shut off any malware java applet that is discovered by revoking its certificate. The unfortunate cost of this is that any casual use of Java is going to be killed. It currently costs a minimum of $100/year and a lot of hoop-jumping to maintain a trusted certificate.'"
An anonymous reader writes "Former US President Bill Clinton, through the Clinton Global Initiative, has awarded $1 million to a group of Canadian MBA students who are looking to solve urban hunger by feeding people insects. The students will use this as seed money for their start-up, Aspire Food Group, which aims to farm, produce, and sell edible insects as a way of solving world hunger, particularly in slums. Aspire says it will even work toward replacing livestock farms with insect farms in some areas." Insects as food aren't necessarily incompatible with conventional livestock, either.
cartechboy writes "You knew the day was coming when they started selling diapers. Amazon is now dipping its toe into car sales by selling a single car: the 2014 Nissan Versa Note. Amazon users hit a real live Versa Note product page, but instead of "Add to cart" you provide your ZIP code so Amazon can connect you with a nearby Nissan dealer. The first 100 Versa Note customers whose car purchases are initiated through Amazon receive $1,000 Amazon gift cards. Best part: Customers who end up actually buying the Note *will* receive them via boxed home delivery. Now, that's a big box." (The linked article says that "some" customers will get their Versa boxed; maybe this is only if you specify gift wrapping.)
michaelmalak writes "In a technique that reminds me of the just-in-time torpedo engineering of Star Trek VI: The Undiscovered Country, a company called Argon Design has "developed a high performance trading system" that puts an FPGA — and FPGA-based trading algorithms — right in the Ethernet switch. And it isn't just to cut down on switch/computer latency — they actually start assembling and sending out the start of an Ethernet packet simultaneously with receiving and decoding incoming price quotation Ethernet packets, and decide on the fly what to put in the outgoing buy/sell Ethernet packet. They call these techniques 'inline parsing' and 'pre-emption.'"
Nerval's Lobster writes "Just as the Internet fundamentally altered the way games are distributed from publishers to players, crowdfunding has upended the traditional models of raising money for gaming development, and some of the most storied people in the industry are taking notice. Chris Roberts, who created the well-known Wing Commander series in 1990, managed to raise millions of dollars on Kickstarter last fall for his upcoming Star Citizen, eventually collecting so much money from individual backers that he could return the budget he'd taken from "formal" investment firms. "Even nice investors, they want a return at some point. They have a slightly diff agenda than I do," Roberts told Slashdot. "My agenda is to build the coolest game possible." He's not the only famed developer getting into the crowdfunding game: Wasteland director Brian Fargo spent years wanting to make a sequel to his popular role-playing game, eventually accomplishing that goal via Kickstarter. And for every famous game creator who uses the power of crowds to produce a new masterwork, dozens of talented amateurs are also financing their first games via Kickstarter and similar services. But that doesn't mean there are occasional high-profile implosions, like CLANG."
KentuckyFC writes "The remarkable growth of mobile phone use is transforming many parts of Africa. In Sudan and Gabon, more than half of all adults use their phones to transfer money, the activist website Ushahidi used text messages to map post-election violence in Kenya in 2008 and in Nigeria, mobile music services are a multi-million dollar industry. Now demographers have used the way people purchase airtime to map wealth in Cote d'Ivoire on Africa's west coast. They analysed a dataset from one of the country's largest mobile operators containing caller IDs, the cell towers used for each call and the time and amount of all airtime purchases. The researchers say an individual's airtime buying habits are a good proxy for his or her income. As a result, they were able to to map wealth across the entire country. Their map clearly shows the wealthy cities such as Abidjan, the largest seaport in West Africa. But it also shows an unexpectedly wealthy region in the conflict-ridden area that borders Liberia. This wealth probably arises from illegal activities on the border, such as drug, arms and human trafficking, they conclude."

nk497 writes "If Google can block child abuse images, it can also block piracy sites, according to a report from MPs, who said they were 'unimpressed' by Google's 'derisorily ineffective' efforts to battle online piracy, according to a Commons Select Committee report looking into protecting creative industries. John Whittingdale MP, the chair of the Committee — and also a non-executive director at Audio Network, an online music catalogue — noted that Google manages to remove other illegal content. 'Google and others already work with international law enforcement to block for example child porn from search results and it has provided no coherent, responsible reason why it can't do the same for illegal, pirated content,' he said."
cagraham writes "BitTorrent has released a new file format called Bundle into closed alpha-testing today, according to VentureBeat. The format allows artists to embed a paywall inside of their work, and then distribute the art for free over BitTorrent. When users open the work they can listen or view part it for free, and are then prompted to either pay a fee, turn over their email address, or perhaps share the work over social media, in order to see the rest. The new format may ease artists concerns about releasing work for free and having to hope for compensation in the future. Artists who have already signed on include Madonna, The Pixies, and author Tim Feriss."
Trailrunner7 writes "While Congress and the technology community are still debating and discussing the intelligence gathering capabilities of NSA revealed in recent months, the agency's director, Gen. Keith Alexander, is not just defending the use of these existing tools, but is pitching the idea of sharing some of the vast amounts of threat and vulnerability data the NSA and other agencies possess with organizations in the private sector. Speaking at a time of great scrutiny of the agency and its activities, Alexander said that the NSA, along with other federal agencies such as the FBI, Department of Homeland Security and CIA, need to find a way to share the attack and vulnerability information they collect in order to help key private organizations react to emerging threats. Though the idea is still in its formative stages, Alexander said that it potentially could include companies in foreign countries, as well. 'We need the authority for us to share with them and them to share with us. But because some of that information is classified, we need a way to protect it,' Alexander said during a keynote speech at the Billington Cybersecurity Summit here Wednesday. 'Right now, we can't see what's happening in real time. We've got to share it with them, and potentially with other countries.'"
sciencehabit writes "Medical experts have been powerless to stop the rise of antibiotic-resistant bacteria and are increasingly desperate to develop novel drugs. But a new study finds that smarter use of current antibiotics could offer a solution. Researchers were able to keep resistant bacteria from thriving by alternating antibiotics to specifically exploit the vulnerabilities that come along with resistance—a strategy that could extend the lifespan of existing drugs to continue fighting even the most persistent pathogens."
