The Myths and Realities of Synthetic Bioweapons

Slashdot - Fri, 19/09/2014 - 08:04
Lasrick writes Three researchers from King's College, London, walk through the security threats posed by synthetic and do-it-yourself biology, assessing whether changes in technology and associated costs make it any easier for would-be terrorists to pursue biological weapons for high-consequence, mass- casualty attacks (and even whether they would want to). "Those who have overemphasized the bioterrorism threat typically portray it as an imminent concern, with emphasis placed on high-consequence, mass-casualty attacks, performed with weapons of mass destruction (WMD). This is a myth with two dimensions."

Europeans Came From Three Ancestry Groupings

Slashdot - Fri, 19/09/2014 - 06:33
Taco Cowboy writes A recent study by researchers at Harvard Medical School and the University of Tübingen in Germany has found that present day Europeans are descendants of three different groups of people — A near east farmer group, an indigenous hunter gatherer group, and an ancient North Eurasian group from Siberia. "Nearly all Europeans have ancestry from all three ancestral groups," said Iosif Lazaridis, a research fellow in genetics in Reich's lab and first author of the paper. "Differences between them are due to the relative proportions of ancestry. Northern Europeans have more hunter-gatherer ancestry — up to about 50 percent in Lithuanians — and Southern Europeans have more farmer ancestry." The most surprising part of the project, however, was the discovery of the Basal Eurasians. Before Australian Aborigines, New Guineans, South Indians, Native Americans and other indigenous hunter-gatherers split, they split from Basal Eurasians. The study also found that Mediterranean groups such as the Maltese, as well as Ashkenazi Jews, had more Near East ancestry than anticipated, while far northeastern Europeans such as Finns and the Saami, as well as some northern Russians, had more East Asian ancestry in the mix.

Study: Chimpanzees Have Evolved To Kill Each Other

Slashdot - Fri, 19/09/2014 - 05:24
sciencehabit writes A major new study of warfare in chimpanzees finds that lethal aggression can be evolutionarily beneficial in that species, rewarding the winners with food, mates, and the opportunity to pass along their genes. The findings run contrary to recent claims that chimps fight only if they are stressed by the impact of nearby human activity—and could help explain the origins of human conflict as well.

Dealership Commentator: Tesla's Going To Win In Every State

Slashdot - Fri, 19/09/2014 - 01:18
cartechboy writes Unless you've been in a coma for a while you're aware that many dealer associations have been causing headaches for Tesla in multiple states. The reason? They are scared. Tesla's new, different, and shaking up the ridiculously old way of doing things. But the thing is, Tesla keeps winning. Now Ward's commenter Jim Ziegler, president of Ziegler Supersystems in Atlanta, wrote an opinion piece that basically says Tesla's going to prevail in every state against dealer lawsuits. He says Tesla's basically busy defending what are nuisance suits. This leads to the question of whether there will be some sort of sweeping federal action in Tesla's favor.

Microsoft Lays Off 2,100, Axes Silicon Valley Research

Slashdot - Fri, 19/09/2014 - 01:06
walterbyrd writes with news of Microsoft layoffs. Microsoft Corp will close its Silicon Valley research-and-development operation as part of 2,100 layoffs announced on Thursday, as it moves toward its new CEO's goal of cutting 18,000 staff, or about 14 percent of its workforce. News of the closure of the Microsoft Research lab at the company's campus in Mountain View, California, was first made public on Twitter by employees. The company later confirmed the move and said it would involve the loss of 50 jobs.

Apple's "Warrant Canary" Has Died

Slashdot - Fri, 19/09/2014 - 00:34
HughPickens.com writes When Apple published its first Transparency Report on government activity in late 2013, the document contained an important footnote that stated: "Apple has never received an order under Section 215 of the USA Patriot Act. We would expect to challenge such an order if served on us." Now Jeff John Roberts writes at Gigaom that Apple's warrant canary has disappeared. A review of the company's last two Transparency Reports, covering the second half of 2013 and the first six months of 2014, shows that the "canary" language is no longer there suggesting that Apple is now part of FISA or PRISM proceedings. Warrant canaries are a tool used by companies and publishers to signify to their users that, so far, they have not been subject to a given type of law enforcement request such as a secret subpoena. If the canary disappears, then it is likely the situation has changed — and the company has been subject to such request. This may also give some insight into Apple's recent decision to rework its latest encryption in a way that makes it almost impossible for the company to turn over data from most iPhones or iPads to police.

Mystery Signal Could Be Dark Matter Hint In ISS Detector

Slashdot - Thu, 18/09/2014 - 23:51
astroengine writes Analysis of 41 billion cosmic rays striking the Alpha Magnetic Spectrometer particle detector aboard the International Space Station shows an unknown phenomena that is "consistent with a dark matter particle" known as a neutralino, researchers announced Thursday. Key to the hunt is the ratio of positrons to electrons and so far the evidence from AMS points in the direction of dark matter. The smoking gun scientists look for is a rise in the ratio of positrons to electrons, followed by a dramatic fall — the telltale sign of dark matter annihilating the Milky Way's halo, which lies beyond its central disk of stars and dust. However, "we have not found the definitive proof of dark matter," AMS lead researcher Samuel Ting, with the Massachusetts Institute of Technology and CERN in Switzerland, wrote in an email to Discovery News. "Whereas all the AMS results point in the right direction, we still need to measure how quickly the positron fraction falls off at the highest energies in order to rule out astrophysical sources such as pulsars." But still, this new finding is a tantalizing step in the dark matter direction.

A Beginner's Guide To Programming With Swift

Slashdot - Thu, 18/09/2014 - 22:46
Nerval's Lobster (2598977) writes Earlier this year, Apple executives unveiled Swift, which is meant to eventually replace Objective-C as the programming language of choice for Macs and iOS devices. Now that iOS 8's out, a lot of developers who build apps for Apple's platforms will likely give Swift a more intensive look. While Apple boasts that Swift makes programming easy, it'll take some time to learn how the language works. A new walkthrough by developer David Bolton shows how to build a very simple app in Swift, complete with project files (hosted on SourceForge) so you can follow along. A key takeaway: while some Swift features do make programming easier, there's definitely a learning curve here.

New Study Projects World Population of 11B by 2100

Slashdot - Thu, 18/09/2014 - 20:18
vinces99 (2792707) writes Using modern statistical tools, a new study led by the University of Washington and the United Nations finds that world population is likely to keep growing throughout the 21st century. The number of people on Earth is likely to reach 11 billion by 2100, the study concludes, about 2 billion higher than widely cited previous estimates. The paper published online Sept. 18 in the journal Science includes the most up-to-date numbers for future world population, and describes a new method for creating such estimates. "The consensus over the past 20 years or so was that world population, which is currently around 7 billion, would go up to 9 billion and level off or probably decline," said corresponding author Adrian Raftery, a UW professor of statistics and of sociology. ... The paper explains the most recent United Nations population data released in July. This is the first U.N. population report to use modern statistics, known as Bayesian statistics, that combines all available information to generate better predictions. Most of the anticipated growth is in Africa, where population is projected to quadruple from around 1 billion today to 4 billion by the end of the century. The main reason is that birth rates in sub-Saharan Africa have not been going down as fast as had been expected. There is an 80 percent chance that the population in Africa at the end of the century will be between 3.5 billion and 5.1 billion people.

Apple Will No Longer Unlock Most iPhones, iPads For Police

Slashdot - Thu, 18/09/2014 - 17:59
SternisheFan writes with this selection from a story at the Washington Post: Apple said Wednesday night that it is making it impossible for the company to turn over data from most iPhones or iPads to police — even when they have a search warrant — taking a hard new line as tech companies attempt to blunt allegations that they have too readily participated in government efforts to collect user data. The move, announced with the publication of a new privacy policy tied to the release of Apple's latest mobile operating system, iOS 8, amounts to an engineering solution to a legal dilemma: Rather than comply with binding court orders, Apple has reworked its latest encryption in a way that makes it almost impossible for the company – or anyone else but the device's owner – to gain access to the vast troves of user data typically stored on smartphones or tablet computers. The key is the encryption that Apple mobile devices automatically put in place when a user selects a passcode, making it difficult for anyone who lacks that passcode to access the information within, including photos, e-mails, recordings or other documents. Apple once kept possession of encryption keys that unlocked devices for legally binding police requests, but will no longer do so for iOS8, it said in a new guide for law enforcement. "Unlike our competitors, Apple cannot bypass your passcode and therefore cannot access this data," Apple said on its Web site. "So it's not technically feasible for us to respond to government warrants for the extraction of this data from devices in their possession running iOS 8."

Alice Is Killing Trolls But Patent Lawyers Will Strike Back

Slashdot - Thu, 18/09/2014 - 17:17
snydeq writes The wheels of justice spin slowly, but they seem finally to be running software patents out of town, writes Simon Phipps in his analysis of how Alice Corp. v CLS Bank is becoming a landmark decision for patent cases in the U.S. 'In case after case, the Court of Appeals is using Alice to resolve patent appeals. In each case so far, the Court of Appeals has found the software patents in question to be invalid. ... As PatentlyO points out, the Alice effect is even reaching to lower courts, saving the Court of Appeals from having to strike down patent findings on appeal.' Although the patent industry broadly speaking sees the Alice verdict as a death knell for many existing patents, some expect Alice to turn software patents into 'draftsmen's art because as you and I have seen over the years, every time there's a court ruling it just means that you have to word the patent claims differently.'

London's Crime Hot Spots Predicted Using Mobile Phone Data

Slashdot - Thu, 18/09/2014 - 14:26
KentuckyFC (1144503) writes A growing number of police forces around the world are using data on past crimes to predict the likelihood of crimes in the future. These predictions can be made more accurate by combining crime data with local demographic data about the local population. However, this data is time consuming and expensive to collect and so only updated rarely. Now a team of data experts have shown how combing crime data with data collected from mobile phones can make the prediction of future crimes even more accurate. The team used an anonymised dataset of O2 mobile phone users in the London metropolitan area during December 2012 and January 2013. They then used a small portion of the data to train a machine learning algorithm to find correlations between this and local crime statistics in the same period. Finally, they used the trained algorithm to predict future crime rates in the same areas. Without the mobile phone data, the predictions have an accuracy of 62 per cent. But the phone data increases this accuracy significantly to almost 70 per cent. What's more, the data is cheap to collect and can be gathered in more or less real time. Whether the general population would want their data used in this way is less clear but either way Minority Report-style policing is looking less far-fetched than when the film appeared in 2002.

Apple Locks iPhone 6/6+ NFC To Apple Pay Only

Slashdot - Thu, 18/09/2014 - 08:08
Ronin Developer writes From the Cnet article: "At last week's Apple event, the company announced Apple Pay — a new mobile payments service that utilizes NFC technology in conjunction with its Touch ID fingerprint scanner for secure payments that can be made from the iPhone 6, iPhone 6 Plus or Apple Watch. Apple also announced a number of retailers that would accept Apple Pay for mobile payments at launch. However, Cult of Mac reports that NFC will be locked to the Apple Pay platform, meaning the technology will not be available for other uses. An Apple spokesperson confirmed the lock down of the technology, saying developers would be restricted from utilizing its NFC chip functionality for at least a year. Apple declined to comment on whether NFC capability would remain off limits beyond that period." So, it would appear, for at least a year, that Apple doesn't want competing mobile payment options to be available on the newly released iPhone 6 and 6+. While it's understandable that they want to promote their payment scheme and achieve a critical mass for Apple Pay, it's a strategy that may very well backfire as other other mobile payment vendors gain strength on competing platforms.

Are Matt's Robot Hexapods Creepy or Cute? (Video)

Slashdot - Wed, 17/09/2014 - 23:03
University of Arizona grad student Matt Bunting doesn't come across as a mad scientist. That's a very good thing, because his robot hexapod creations are easy to imagine crawling across the USA in large hordes, devouring everything in their path and using all the electricity they come across to feed their Queen Hexapod, a 3-D printer mounted on a hexapod chassis that turns everything fed to it into more robots. Luckily, the real life Matt is an affable (self-described) "Roboticist, Electrical Engineer, Musician, and Rock Crawler" who freely admits that at this time his robotic creations have no practical application whatsoever. This is probably true, except for the fact that they can liven up a music video like mad, as you can see on YouTube in Pedals Music Video (featuring REAL robots) . Our little video is a lot simpler, of course. In it, we interview Matt and he tells us what he's up to with his robots, and gives some 'how to get started with robotics' advice for budding young engineers. (Alternate Video Link)

eBay Redirect Attack Puts Buyers' Credentials At Risk

Slashdot - Wed, 17/09/2014 - 21:35
mrspoonsi points out this BBC story about an eBay breach that was directing users to a spoof site. "eBay has been compromised so that people who clicked on some of its links were automatically diverted to a site designed to steal their credentials. The spoof site had been set up to look like the online marketplace's welcome page. The firm was alerted to the hack on Wednesday night but removed the listings only after a follow-up call from the BBC more than 12 hours later. One security expert said he was surprised by the length of time taken. 'EBay is a large company and it should have a 24/7 response team to deal with this — and this case is unambiguously bad,' said Dr Steven Murdoch from University College London's Information Security Research Group. The security researcher was able to analyze the listing involved before eBay removed it. He said that the technique used was known as a cross-site scripting (XSS) attack."
