Tummy problems? Just swallow this stomach-repairing origami robot made of meat

(credit: Melanie Gonick/MIT ) A chunk of meat that bursts open once eaten and unleashes a robot that crawls around inside of your stomach sounds like something from a horror movie. But the real-life stomach-roaming meat robot actually means no harm—on the contrary, it was designed to doctor your stomach troubles from the inside. On Thursday, researchers at MIT revealed the origami meat robot that they designed to patch stomach wounds, deliver medicine, and remove dangerous foreign objects that patients may have accidentally swallowed. In early simulations with pig esophagus and gut tissue, the robot traveled down to the stomach in an ice capsule that melted along the way. Once there, the robot unfolded and could be steered around the stomach using external magnets. In a demonstration video provided by MIT News , the researchers show that the robot can move a button battery in their simulation stomach. The researchers presented their robot this week at the International Conference on Robotics and Automation. “It’s really exciting to see our small origami robots doing something with potential important applications to health care,” said Daniela Rus, lead researcher on the study and director of MIT’s Computer Science and Artificial Intelligence Laboratory.

Walmart sues Visa, wants to require PINs for all chip-enabled debit cards

This week,  Walmart sued Visa  in New York State Court, saying it wanted to be able to require PIN authorizations on all EMV debit card transactions. Although many debit card transactions already require a PIN to authorize purchases or withdrawals on that card, Visa makes its merchants give Visa card holders the option to authorize with a signature. Walmart is arguing that this puts its customers at risk for fraud. Visa, Mastercard, and other card networks set an October 2015 deadline for merchants and card issuers in the US to shift to the chip-based EMV standard (which is eponymous for Europay, Mastercard, and Visa, the three groups that developed the standard). The transition was meant to replace the magnetic stripe cards that persisted for years in the US, even after other countries quickly made the transition to the more secure chip-based cards. Walmart made the transition early last year, becoming one of the first national retailers to buy new terminals that accepted EMV cards, the Wall Street Journal reports. But even though the EMV standard accepts PIN authorization on all cards, the major card networks said they would allow signature authorization to persist in the US and not require PIN authorization, claiming that it would minimize confusion among customers who might have trouble adapting to the new standard. Others objected to the authorization leniency, arguing that signature authorization does nothing to prevent fraud against a card holder if their card is physically stolen. In a statement to the WSJ , Walmart said that the suit was about “protecting our customers’ bank accounts when they use their debit cards at Walmart.” Still, the paper notes that there’s a monetary side to Walmart’s legal salvo as well—for every signature-authorized transaction, Walmart must pay Visa five cents more than it does on a PIN-authorized transaction. According to the WSJ , about 10 percent of Visa debit-card-using customers at Walmart will ask to override the PIN authorization prompt at the checkout counter in favor of authorizing the transaction with a signature. Mastercard, on the other hand, lets retailers choose how they will allow customers to authorize transactions. Walmart has fought against card networks and issuers for years. One of its most recent battles involved leading a consortium of retailers to create the Merchant Customer Exchange, known as MCX , which tried and failed to launch CurrentC, a system that would authorize payments to the store directly from a customer’s checking account with the help of a QR code on the customer’s phone, essentially circumventing the interchange fees paid by the retailer to the credit card companies . When CurrentC failed , Walmart launched Walmart Pay in a continued attempt to wrest control from mobile payment systems like Apple Pay and Android Pay.

Windows 10’s Wi-Fi credential sharing is going away in the Anniversary Update

Last night, a new Windows 10 Insider Preview unexpectedly made its way onto the Internet after Microsoft accidentally started releasing it to end users while sending it to Windows Update. The new build, 14342, takes some big steps forward in Edge’s extension support. Previously,  extensions in the Edge browser had to be manually downloaded and installed. Now they are installed and updated in the same way as Universal Windows Apps. The number of extensions available for Edge has also grown, with a couple of ad blockers now joining the fray. With this build, Microsoft is starting to bring back some of the more tablet-oriented features that were in Windows 8 but removed from Windows 10. Swipe navigation in the browser is now back, allowing you to navigate back and forward just by swiping the page left and right. The next Mobile build will also include this capability.

3,000-year-old female mummy was covered in hidden tattoos

On the 3,000-year-old mummy’s neck, you can see two seated baboons on either side of a wadjet eye (top row), which is a symbol of protection. 5 more images in gallery Covered in more than 30 tattoos of flowers, animals, and sacred symbols, this 3,000-year-old mummy is one of the most unusual that archaeologist Anne Austin has ever seen. Though other mummies have been found with abstract markings like dots tattooed on their skin, no one had ever seen figurative drawings like these. Austin and her colleagues were stunned. The mummy, found in a village called Deir el-Medina, was once a woman who proudly inked sacred wadjet eyes on her neck, shoulders, and back, lotus blossoms on her hips, and cows on her arm. Her village was home to artisans who worked in the nearby Valley of the Kings, where they would have carved elaborate sculptures and inscriptions for pharaohs and gods. It’s not clear what the tattoos meant nor why this particular woman had so many of them. But Austin speculates that they had religious significance, particularly the eyes and the cows, which may have been a reference to the goddess Hathor. “Any angle that you look at this woman, you see a pair of divine eyes looking back at you,” she told Nature  after presenting her work at the American Association of Physical Anthropologists. She first discovered the tattoos when she saw the eye and baboons clearly visible on the mummy’s neck. Suspecting there might be more, she used infrared imaging to see ink that had penetrated the woman’s skin but was no longer visible due to dark resins used for mummification. This is the same technique that scientists used to discover the tattoos on the body of Ötzi the Iceman , a 5,300-year-old body that was accidentally preserved in ice for thousands of years. Ötzi had more than 60 tattoos created with ash that were entirely abstract, mostly horizontal lines on parts of his body where joint swelling suggests that he would have been suffering pain. When Austin used infrared imaging, she was able to find many tattoos that were previously hidden. The tattoos on the woman’s back became visible, and Austin and her colleagues used image reconstruction software to correct distortions that were introduced when the mummy’s skin shrank over time. Once the tattoos were stretched, she could clearly see the two cows on the woman’s arm and many other images. Some of the tattoos, she says, were in places where it would have been extremely painful to be tattooed, especially because the process would have been very slow in ancient times. They were also clearly created by someone else, since many were on the woman’s back. These facts suggest the tattoos may have had deep cultural significance. There is also evidence that some of the tattoos were faded, so the woman was probably getting new ink for many years as older tattoos faded. Read 1 remaining paragraphs | Comments

FDA flexes regulatory muscles, says vaping, e-cigs now under its control

(credit: Flickr/ecig click ) The US Food and Drug Administration announced Thursday that it has extended its authority and will now regulate electronic cigarettes, hookah tobacco, cigars, and other tobacco products under the 2009 Family Smoking Prevention and Tobacco Control Act . The regulatory move, first proposed in 2014, is largely aimed at protecting kids from tobacco and nicotine products. The result is that e-cigs and the other products will now be subject to the same federal regulations as regular cigarettes. These regulations include some relatively uncontroversial rules such as a ban on selling e-cigs to minors (which some states have already done), requiring a photo ID to buy e-cigs, not selling e-cigs out of vending machines, and a ban on free e-cig samples. But the regulations also require that e-cigarette manufactures register with the agency and put any new devices through a pre-market regulatory approval process. By “new,” the FDA means any novel devices put on the market after February 15, 2007. Devices released before then will be grandfathered into the regulations. However, in the relatively young e-cig market, the vast majority of current products were introduced after 2007 and will be subject to the approval process. Read 6 remaining paragraphs | Comments

Verizon: Network sabotage during strike disrupted thousands of customers

Poorly maintained equipment, as shown in a union complaint about Verizon maintenance. (credit: Communications Workers of America ) Verizon says its network has suffered 57 incidents of vandalism in seven states in the two weeks since 36,000 workers went on strike . The “incidents of sabotage,” mostly involving the severing of fiber optic cables or damage to terminal boxes, “have cut off thousands of Verizon customers from critical wireline services,” the company said Wednesday . Under normal conditions, there are only about a half-dozen incidents of sabotage over the course of a year, a Verizon spokesperson told Ars today. Verizon says it is still investigating the incidents and hasn’t pinned the blame on anyone specific. But the company’s announcement pointed out that “these malicious actions take place as Verizon is experiencing a strike.” Verizon reported similar incidents of vandalism during another  strike in 2011 .

The Wheel of Time turns… into a “cutting-edge TV series”

Cover art for the first Wheel of Time novel. (credit: Tor Books) After a rough false start , it looks like Robert Jordan’s fantasy epic  The Wheel of Time will be coming to television after all. The news was delivered on the series’ Google+ page by Jordan’s widow, Harriet McDougal, who owns the copyright to the novels and has controlled the franchise’s direction since Jordan’s death in 2007. We have few details about the project at this point, aside from assurances that a “major studio” will have more to share soon: Wanted to share with you exciting news about The Wheel of Time . Legal issues have been resolved. The Wheel of Time will become a cutting edge TV series! I couldn’t be more pleased. Look for the official announcement coming soon from a major studio —Harriet Optioning  The Wheel of Time makes sense, given the appetite for TV adaptations of dense, sprawling fantasy series. HBO’s  Game of Thrones  and Starz’s  Outlander have both been successful, and  Wheel of Time  is a firmly established property that has the added benefit of actually being a finished story already.

From TV trailblazer to IP afterthought: TiVo bought for $1.1 billion

(credit: cncphotos ) Entertainment company Rovi announced that it has officially acquired DVR maker TiVo in a deal worth $1.1 billion. Rovi will pay for the deal mostly in stock at $10.70 per share, with approximately $277 million to be paid in cash at $2.75 per share. Rovi’s CEO Tom Carson will continue to run the company, although it will now assume the “iconic TiVo brand” as its name. The deal seems to be centered on patents. According to The New York Times , Rovi’s interactive TV program guides account for less than half of its $526 million revenue last year, while the rest is made up of its licensed intellectual property. TiVo made a name for itself with its DVR technology, but the patents that make its DVR hardware and software work are proving to be more valuable. Together, Rovi and TiVo have over 6,000 patents issued and pending in the digital entertainment space. “Rovi’s acquisition of TiVo, with its innovative products, talented team, and substantial intellectual property portfolio, strengthens Rovi’s position as a global leader in media discovery, metadata, analytics, and IP licensing,” Carson said in a statement . “It’s an exciting time as the media and entertainment landscape undergoes a significant evolution…. By working together, Rovi and TiVo will revolutionize how consumers experience media and entertainment and at the same time build value for our stockholders.” Read 1 remaining paragraphs | Comments

Microsoft experiments with DNA storage: 1,000,000,000 TB in a gram

Microsoft is buying ten million strands of DNA from biology startup Twist Bioscience to investigate the use of genetic material to store data. The data density of DNA is orders of magnitude higher than conventional storage systems, with 1 gram of DNA able to represent close to 1 billion terabytes (1 zettabyte) of data. DNA is also remarkably robust; DNA fragments thousands of years old have been successfully sequenced. These properties make it an intriguing option for long-term data archival. Binary data has already been successfully stored as DNA base pairs , with estimates in 2013 suggesting that it would be economically viable for storage of 500 years or more.

New Windows 10 build: New Start menu, notifications, and pen features

The new Pen Workspace. (credit: Microsoft) At its Build developer conference a few weeks ago, Microsoft announced the Windows 10 Anniversary Update, a major update for Windows 10 due this summer. One of its biggest aspects was substantially reworked and improved pen support (“Ink” in Microsoft terminology) intended to make pen applications easier to find and use and to make stylus use more powerful. A new Windows build that provides the first access to these new features, version 14328, has just been promoted to the fast ring . The core of this new support is the Windows Ink Workspace, a panel that provides instant access to pen-powered apps. Pressing the eraser button on a Surface Pen will show the panel instead of its current action (which opens OneNote). The Anniversary Update also comes with a trio of new pen apps: Sketchpad, a sketching app; Screen sketch, a screenshot annotation app; and a new Sticky Note app. New Sticky Notes. (credit: Microsoft) The new build contains a lot more than just Ink improvements. The Start menu has been revised to make All Apps permanently visible, and in tablet mode, All Apps is now full-screen. Also in tablet mode, the taskbar can autohide without being autohide in desktop mode. The taskbar clock now shows on all monitors on multihead systems, and the calendar now shows your appointments. The Action Center notification system has had its layout refined to show more notifications and now includes rich Cortana notifications. Read 3 remaining paragraphs | Comments
