Skeleton from one of the earliest Americans yields its genome

The burial mound in Montana where the skeleton was found. Texas A&M University The peopling of the Americas via the Bering Sea land bridge is one of the more confusing events in recent history. Some of the earliest signs of human occupancy are actually in Chile. After that, the first distinct toolmaking culture, the Clovis people, appeared in the interior of North America, and rapidly swept across the continent. There are also indications that a separate migration occurred down the Pacific coast, possibly associated with people who had distinctive skeletal features, while the Inuit seem to be relatively recent arrivals. The sudden appearance of the Clovis toolset has caused some people to suggest that the Clovis were a distinct migration by a passage between ice sheets directly into North America’s interior. Others have even suggested that they arrived from Europe, brought by people who crossed the ice through Greenland (an idea that’s favored by a certain Bigfoot researcher ). Now, researchers have completed the genome of an individual who was buried with Clovis tools in Montana 12,500 years ago. The results suggest that the migration into North America was more unified than some thought. Although Clovis tools are relatively common at many North American sites, they’re generally not associated with skeletal remains. And there have been no distinctive skeletal features that label remains as belonging to a distinctive Clovis ethnic group. All of which makes Montana’s Anzick site exceptional: it contains remains that were placed with Clovis tools, unambiguously tagging the skeleton as belonging to this group.

Giant leap for nuclear fusion as scientists get more energy out than fuel put in

Lawrence Livermore National Laboratroy Researchers in the US have overcome a key barrier to making nuclear fusion reactors a reality. In results published in Nature , scientists have shown that they can now produce more energy than the fuel put into an experiment. The use of fusion as a source of energy remains a long way off, but the latest development is an important step toward that goal. Nuclear fusion is the process that powers the sun and billions of other stars in the universe. If mastered, it could provide an unlimited source of clean energy because the raw materials are plentiful and the operation produces no carbon emissions. During the fusion process, smaller atoms fuse into larger ones releasing huge amounts of energy. To achieve this on Earth, scientists have to create conditions similar to those at the center of the sun. This involves creating very high pressures and temperatures.

Slashdot’s new interface could kill what keeps Slashdot relevant

In the modern responsive Web Three Point Oh Internet, Slashdot stands like a thing frozen in time—it’s a coelacanth stuck incongruously in an aquarium full of more colorful fish. The technology news aggregator site has been around since 1997, making it positively ancient as websites are reckoned. More importantly, Slashdot’s long focus on open source technology news and topics has caused it to accrete a user base that tends to be extremely technical, extremely skilled, and extremely opinionated. That user base is itself the main reason why Slashdot continues to thrive, even as its throwback interface makes it look to untrained eyes like a dated relic. Though the site is frequently a source of deep and rich commentary on topics, the barrier for new users to engage in the site’s discussions is relatively high—certainly higher than, say, reddit (or even Ars). This doesn’t cause much concern to the average Slashdot user, but tech job listing site Dice.com (which bought Slashdot in September 2012, along with Sourceforge and a number of other digital properties) appears to have decided it’s time to drag Slashdot’s interface into the 21st century in order to make things comfortable for everyone—old and new users alike. And the Slashdot user base is not pleased. Read 16 remaining paragraphs | Comments

Biggest DDoS ever aimed at Cloudflare’s content delivery network

Ruthanne Reid A distributed denial-of-service attack targeting a client of the content delivery network Cloudflare reached new highs in malicious traffic today , striking at the company’s data centers in Europe and the US. According to a Twitter post by Cloudflare CEO Matthew Prince, the full volume of the attack exceeded 400 gigabits per second—making it the largest DDoS attack ever recorded. The attack used Network Time Protocol (NTP) reflection , the same technique used in recent attacks against gaming sites by a group called DERP Trolling. NTP is used to synchronize the time settings on computers across the Internet. The attack made fraudulent synchronization requests to NTP servers that caused them to send a flood of replies back at the targeted sites. Reflection attacks have been a mainstay of DDoS tools and botnets, but the use of NTP in such attacks is relatively new. Last year’s attack on Spamhaus , which previously set the record for the largest DDoS ever, used a Domain Name Service (DNS) protocol attack—a much more common approach that takes advantage of the Internet’s directory service, forging requests for DNS lookups from the intended target and sending them to scores of open DNS servers. The size of the traffic directed back at the target from these requests far exceeds the size of the requests sent to the DNS servers, which is why the technique is often called a DNS amplification attack.

Spectacular new Martian impact crater spotted from orbit

NASA/JPL/University of Arizona Yesterday, the team that runs the HiRISE camera on the Mars Reconnaissance Orbiter released the photo shown above. It’s a new impact crater on Mars, formed sometime early this decade. The crater at the center is about 30 meters in diameter, and the material ejected during its formation extends out as far as 15 kilometers. The impact was originally spotted by the MRO’s Context Camera , a wide-field imaging system that (wait for it) provides the context—an image of the surrounding terrain—for the high-resolution images taken by HiRISE. The time window on the impact, between July 2010 and May 2012, simply represents the time between two different Context Camera photos of the same location. Once the crater was spotted, it took until November of 2013 for another pass of the region, at which point HiRISE was able to image it. Higher-resolution photos, as well as a map of the crater’s location on Mars, are available from the HiRISE website. Read on Ars Technica | Comments

Dread Pirate Roberts 2.0: An interview with Silk Road’s new boss

Aurich Lawson Silk Road, the infamous and anonymous online marketplace specializing in illicit goods, sells everything from pot to black tar heroin. If you can smoke it, inject it, or snort it, there’s a good chance Silk Road has it. Well, had it. Late last year, the FBI burst into a local branch of the San Francisco Public Library and arrested one Ross Ulbricht, the alleged kingpin who ran the site. It all happened while Ulbricht’s laptop was open and he was logged into his encrypted accounts. In the days that followed, the feds dropped a host of charges on Ulbricht, including several salacious accusations that Ulbricht attempted to arrange hits on various people he thought had betrayed him or blackmailed him. The feds also arrested several people accused of being major sellers, creating anxiety for those who ever bought or sold on the site. The Silk Road was closed . It didn’t take long to return. Just as the previous Silk Road operator had done, the new owner called himself “Dread Pirate Roberts” (DPR). The name came from a character in The Princess Bride who passes his piratical business down from one individual to the next, each of whom uses the same name to ensure continuity. So in a move that would seem to tempt fate, the new DPR built another version of Silk Road and restarted the drug marketplace. Read 42 remaining paragraphs | Comments

11 high school students expelled for keylogging teachers’ computers

Corona del Mar sits on an idyllic part of the Orange County coastline. Mark Weston A hacking scandal involving keyloggers and electronic grade-changing at a high school in Newport Beach, a well-to-do area of Southern California, has resulted in the expulsion of 11 students. The Orange County Register reported Wednesday that six of those students had already left the district, but five had been transferred to another local school. “The Board’s action imposes discipline upon these students for the maximum allowed by the Education Code for what occurred at Corona del Mar High School,” Laura Boss, the Newport Mesa Unified School District spokesperson wrote in a statement on Wednesday. US News and World Report ranked the high school in question as the 46 th best within California. Read 23 remaining paragraphs | Comments

Amazon mulling price hike for Amazon Prime shipping and streaming service

Amazon has just reported its earnings for the fourth quarter of 2013 . According to The Verge , Amazon CFO Tom Szkutak mentioned that the company is considering a price increase for its Amazon Prime customers in the US. The decision hasn’t been made, but high shipping costs could prompt a price increase of between $20 and $40 a year for the service. Prime began life as a service that offered free two-day shipping on many items for a flat, $79-a-year fee. As Amazon has branched out into tablets and streaming media, perks like the Instant Video service and Kindle Owners’ Lending Library have been added to sweeten the deal. The potential price increase would be the first since Prime was introduced in the US in 2005. Amazon reported income of $239 million on sales of $25.59 billion for the fourth quarter of 2013, lower than analysts had expected. The company’s guidance for the first quarter of 2014 projects sales between $18.2 and $19.9 billion and expects income to be somewhere between a profit of $200 million and a loss of $200 million.

AT&T plan to shut off Public Switched Telephone Network moves ahead at FCC

PhotoAtelier On Thursday, the Federal Communications Commission is expected to take its first major step toward letting AT&T and other carriers replace the country’s traditional phone system with one that works entirely over Internet Protocol networks. AT&T has argued that the technology transition should be accompanied by deregulation that would strip the company of most of its monopoly-era obligations. AT&T likely won’t get everything it wants, though. FCC Chairman Tom Wheeler wrote in a blog post last November that he intends to “ensure the continuation of the Network Compact” with universal service for all Americans, consumer protections, public safety services, and competition.In other words, AT&T can’t stop maintaining the Public Switched Telephone Network (PSTN) without a plan to preserve current service levels. This is not as simple as just making sure phone calls get through, although solving the rural call completion problem by itself is a challenge. It also means maintaining access to 911 services, fire alarms, fax machines, medical alert systems, anything that relies on the phone network. Not everything is to be decided this week. The FCC vote is on an AT&T petition to launch customer trials of new IP-based networks. While AT&T’s petition is expected to be granted, the FCC’s proposed order is written to ensure continuation of the four values (universal service, consumer protection, public safety, and competition) as Wheeler emphasized, an FCC official told Ars on condition that he not be named.
