Submission + - To Salvage or Sever: What Happens When Your Own Limb Is Almost Good Enough?->

derekmead writes: While the media might focus on prosthetics, the technology and techniques involved in limb salvage have advanced tremendously too, spurred in large part by America’s recent military conflicts.

Now, when a soldier or civilian faces a brutal limb injury, they have choices—save the limb, or amputate. Be a limb salvage patient, or an amputee. Reconstruct the limb you were born with, out of the pieces you have left over, or lose that limb altogether. And that choice is, increasingly, a really difficult one.

Submission + - University Students Made a Working Model Hyperloop->

derekmead writes: Elon Musk's Hyperloop gets people excited. Promise the ability to travel from San Francisco to Los Angeles in less than an hour, and you're going to get people salivating. But for as much as we've heard about it, we've had scarcely little to see—until a team of students at the University of Illinois decided to build their very own miniature hyperloop.

Mechanical engineering students at the university built a functioning 1:24 scale model of the Hyperloop, a “fourth mode of transportation” that sends pods through a partially pressurized tube at very high speeds, as part of a senior design project. It was designed to test some of the key components of Musk's design, which was outlined in a much-read, open source white paper published in August of 2013. That said, there are several key differences, which keep this from truly being a proof-of-concept as to whether or not the Hyperloop will ultimately work.

Submission + - Netflix Is Experimenting with Advertising ->

derekmead writes: Netflix is experimenting with advertisements that run both before and after users watch a video. It's unclear whether or not the company will eventually push ads to everyone.

For now, the company is primarily experimenting with the HBO model of pitching its own original programming to viewers. The company is only showing trailers for shows like Orange Is the New Black and House of Cards—it has not attempted to sell third party ads, and the company told me that, for the moment, only specific users in specific markets are seeing ads.

Submission + - Oldest Stone Tools Predate Previous Record Holder by 700,000 Years->

derekmead writes: Scientists have discovered the oldest stone tools ever found, dating back some 3.3 million years to Pliocene Africa—long before the rise of humans' first ancestors in the Homo genus.

The artifacts were found near Lake Turkana, Kenya, and predate the next oldest tools by a whopping 700,000 years. That is an enormous margin, and it will have far-reaching ramifications for our understanding of how material culture initially arose in early hominin communities. An in-depth analysis of the site, its contents, and its significance as a new benchmark in evolutionary history will be published in the May 21 issue of Nature.

Submission + - Illinois Says Rule-Breaking Students Must Give Teachers Their Facebook Passwords->

derekmead writes: School districts in Illinois are telling parents that a new law may require school officials to demand the social media passwords of students if they are suspected in cyberbullying cases or are otherwise suspected of breaking school rules.

The law (PDF), which went into effect on January 1, defines cyberbullying and makes harassment on Facebook, Twitter, or via other digital means a violation of the state's school code, even if the bullying happens outside of school hours.

A letter sent out to parents in the Triad Community Unit School District #2, a district located just over the Missouri-Illinois line near St. Louis, that was obtained by Motherboard says that school officials can demand students give them their passwords.

Submission + - Tracking the Mole Inside Silk Road 2.0->

derekmead writes: The arrest of the Silk Road 2.0 leader and subsequent seizure of the site was partially due to the presence of an undercover US Department of Homeland Security agent, who “successfully infiltrated the support staff involved in running the Silk Road 2.0 website," according to the FBI.

Referencing multiple interviews, publicly available information, and parts of the moderator forum shared with me, it appears likely that the suspicions of many involved in Silk Road 2.0 are true: the undercover agent that infiltrated the site was a relatively quiet staff member known as Cirrus.

Submission + - Astronomers find star-inside-star 40 years after first theorized->

derekmead writes: After 40 years, astronomers have likely found a rather strange celestial body known as a Thorne–ytkow object (TZO), in which a neutron star is absorbed by a red supergiant. Originally predicted in the 1970s, the first non-theoretical TZO was found earlier this year, based on calculations presented in apaper forthcoming in MNRAS .

TZOs were predicted by astronomer Kip Thorne and Anna ytkow, who wasthen postdoctoral fellow at CalTech. The pair imagined what might happen if a neutron star in a binary system merged with its partner red supergiant.

This wouldn’t be like two average stars merging. Neutron stars are the ancient remnants of stars that grew too big and exploded. Their cores remain small—about 12.5 miles—as they shed material out into space. Red supergiants are the largest stars in the galaxy with radii up to 800 times that of our sun, but they aren’t dense.

Submission + - Japan's Alleged Death Threat-Making, Cat-Hacking Programmer Says He's Innocent->

Daniel_Stuckey writes: Inside the memory card in the cat's collar, authorities found a resentful message criticizing the police along with versions of the virus (iesys.exe) used to carry out the threat messages, which were made remotely, through other people’s computers. If you hadn’t heard about the story in the news, you'd be forgiven for confusing it with the plot of a Haruki Murakami novel.

In Tokyo District Court Wednesday, the former employee of a Japanese IT company wore a black suit, a wide smile, and pleaded not guilty to 10 charges brought against him. The Japan Times explained the string of threats were directed at “schools and kindergartens attended by the Emperor Akihito’s grandchildren,” as well as a Japan Airlines jet headed for New York. The plane had to stop midflight, costing the airline ¥9.75 million (about $93,000).

Submission + - Can't Quit Smoking? Try Blaming Neanderthals-> 1 1

Daniel_Stuckey writes: Humans might have Neanderthals to thank for our smoking addictions, our Type II diabetes, and things like Crohn’s disease, lupus, and our hair types, according to a new genetic analysis by researchers at Harvard University.

We’ve long known that humans and Neanderthals share at least some genetic material—recent estimates put it at about 2 percent—but the Harvard University analysis, published Wednesday in Nature , tells us exactly what we share, something that has only become possible because of new, high-quality genome sequencing. By studying the genetic variability in 846 non-African people, 176 people from sub-Saharan Africa, and the complete genome of a 50,000-year-old Neanderthal, Sriram Sankararaman and his team were able to trace certain alleles from Neanderthals into present-day humans.

The findings are utterly fascinating. The alleles that modern, non-African humans (sub-Saharan Africans are believed to share very little DNA with Neanderthals) share with Neanderthals are associated with things such as nicotine addiction, Type II diabetes, and a host of other diseases.

Submission + - When Will the Internet Defeat Link Rot?->

Daniel_Stuckey writes: A few days ago, I renewed the hosting for a single-serving joke site I haven't updated in more than a year, partially because the domain reggaehorn.com is surely worth millions, and largely because I didn't want to let a a little black hole—unfathomably tiny as it may be—open up in the web.

Obviously, the loss of a completely inconsequential site isn't exactly going to ruin the internet. But as occasionally happens, it got me thinking about how such black holes, most of more importance, are already everywhere. As sites blink offline and pages get lost to the long march of site updates and lapsed hosting fees. For everyone who values the internet as a repository of information—that's all of us—link rot is a corrosive force that's left much of the web perched atop a fragmented foundation of lost sources and dead links. So what can we do about it?

The link rot problem topped the news cycle last fall, when a Harvard Law study found that the US Supreme Court has a serious problem. According to the study, "50% of the URLs found within United States Supreme Court opinions do not link to the originally cited information." A few months earlier, a Yale study found that 29 percent of websites cited in Supreme Court decisions are no longer online.

Submission + - Protesters Dodge the Sudanese Internet Shutdown with a Phone-Powered Crowdmap->

Daniel_Stuckey writes: Called the Abena crowd map, the map is the product of Mohammed Hashim Saleh and Abeer Khairy, engineers both, and Ahmed Hassan, the co-founder of Khartoum Geeks. In the short amount of time the internet was on yesterday, they deployed the map, which follows events on the ground in Sudan with direct reports.

SMS messages are connected automatically with the Ushahidi-based crowdmapping platform, Saleh told me. Activists, some in-country (who work when possible) and the rest outside, login and check the messages. They are then doubled checked with news sources and social media before being finally confirmed and mapped. The crew has also been manually updating the platform.

Submission + - Ford's Mulally emerging as frontrunner for Microsoft CEO job->

colinneagle writes: Speculation is growing that Ford CEO Alan Mulally is not just in the running for the CEO position at Microsoft, but has become the frontrunner among all candidates, both internal and external. One reason, which I did note in my recent blog post on him, is that Mulally was a top executive at Boeing for years and has connections to the Seattle area. Earlier this month, Reuters reported earlier this month that the Ford board had given Mulally the option to step down earlier from his position than is specified in his contract (there was speculation that he might take a position in the Obama administration). Nokia CEO and former Microsoft executive Stephen Elop has remained a top candidate, but interest has shifted toward Mulally because of his experience turning around a faltering company. No one can say Elop turned around Nokia.

Submission + - Al Gore Explains Why Civilization Might Not Survive the Next 100 Years->

Daniel_Stuckey writes: Motherboard sat down with the United States' most famousâ"and surely busiestâ"former vice president at this year's Social Good Summit, where we talked about two possible futures Gore sees confronting humanity.

I asked him to describe the best and worst case scenarios for what civilization might look like 100 years from now. In one, Americans undertake an "Occupy democracy movement" to restore our political system, which Gore says has been "hacked" by money and special interests, and come together to fight climate change. In the other, the whole of human civilization lies in ruin.

Submission + - Where Is the center of each United State?->

Daniel_Stuckey writes: Have you ever spent an extended period of time trying to find, or simply meditating on the center of an object? You know, that sweet spot, where if you picked it up and placed it square on your nose, it would balance perfectly. I've recently found myself obsessed with the concept, but I assure you it has nothing to do with becoming a street performer. The aspect I've become obsessed with is how it applies to the 50 states (and DC). So, in a very OCD-satisfying manner, I made a map:
