A US freeway may get self-driving car lanes thanks to Foxconn

Wisconsin highway planners are studying the possibility of placing driverless vehicle lanes on I-94 to serve Foxconn ‘s mega factory in Racine County. The Taiwanese company — supplier to tech firms including Apple, Microsoft, and Nintendo — reportedly made the suggestion at a meeting with regional officials, according to USA Today ‘s Journal Sentinel . Foxconn’s $10 billion midwest facility will span 20 million square feet and could create up to 13, 000 jobs. That’s an awful lot of humans commuting back and forth from work, and that’s before you take into account the goods getting hauled in. But, seeing as the I-94 highway is getting a bump from six to eight lanes anyway, regional officials figured they were prepared for the uptick in traffic. Foxconn, it seems, has other ideas in mind. While companies like Uber and Waymo are trialing self-driving vehicles on roads across the US, there’s also been talk of dedicated lanes for robocars (and trucks ). Last year, VC firm Madrona Ventures floated the idea for replacing the I-5 freeway between Seattle and Vancouver with an “autonomous vehicle” corridor. But, Foxconn’s desire to yield regular car lanes to driverless vehicles could be a way off yet. A spokesman for the Wisconsin Department of Transportation told the Journal Sentinel that the proposal is just one of many “on the table.” One possibility, according to Tim Sheehy (president of the Metropolitan Milwaukee Association of Commerce), is driverless lanes between the Foxconn plant and Milwaukee’s Mitchell International Airport.

Researchers craft an LED just two atoms thick

Enlarge / Hexagonal boron nitride, one of the materials used here. (credit: Wikimedia Commons ) Modern computers are, in many ways, limited by their energy consumption and cooling requirements. Some of that comes from the process of performing calculations. But often, the majority of energy use comes from simply getting data to the point where calculations are ready to be performed. Memory, storage, data transfer systems, and more all create power draws that, collectively, typically end up using more power than the processor itself. Light-based communications offers the possibility of dropping power consumption while boosting the speed of connections. In most cases, designs have focused on situations where a single external laser supplies the light, which is divided and sent to the parts of the system that need it. But a new paper in Nature Nanotechnology suggests an alternate possibility: individual light sources on the chip itself. To demonstrate this possibility, the team put together an LED just two atoms thick  and integrated it with a silicon chip. Better still, the same material can act as a photodetector, providing a way of building all the needed hardware using a single process. Atomic The work relied on two different atomically thin materials. These materials consist of a planar sheet of atoms chemically linked to each other. While their study was pioneered using graphene, a sheet of carbon atoms, they developed a variety of other materials with similar structures. The materials being used here are molybdenum ditelluride (MoTe 2 ), a semiconductor, and hexagonal boron nitride. Read 7 remaining paragraphs | Comments

IRS hands fraud prevention contract to Equifax despite massive hack

You’d think that government agencies would be reticent to work with Equifax given that it just exposed the private info of more than 145 million people through a preventable hack , but a massive data breach apparently isn’t enough of a deterrent. The Internal Revenue Service recently awarded Equifax a fraud prevention contract that will have it verifying taxpayer identities. And crucially, it was a no-bid, “sole source” contract — Equifax was deemed the only company capable of fulfilling demand. In practice, officials didn’t have much of a choice. Credit reporting in the US is dominated by three large companies (Equifax, Experian and TransUnion), and Equifax is arguably the powerhouse of the bunch. However, that only underscores the problem here: the IRS had to trust a crucial anti-fraud system to a company that not only had sloppy online security practices, but has been reluctant to take full responsibility for its mistakes. There’s a real chance that the hack will get Equifax to clean up its act in time to improve its handling of IRS data. We wouldn’t count on it, though, and there’s always the possibility that the IRS will fall afoul of the kind of data breach that prompted this anti-fraud contract in the first place.

Harvard’s soft exosuit makes walking 23 percent easier

Harvard Wyss Institute researchers have been working on a soft exosuit with DARPA’s financial help for years. While they were able to present a proof of concept in 2016, it’s only now that they’ve found out just how much the suit can actually help its wearer. According to a new study published in Science Robotics , Harvard’s exosuit reduces the energy a user needs to exert while walking by 23 percent. It does that by providing assistive force to the ankle at the perfect moment when you take another step. Team leader Conor Walsh said that’s the highest percentage of reduction in energy use observed with an exosuit: “In a test group of seven healthy wearers, we clearly saw that the more assistance provided to the ankle joints, the more energy the wearers could save with a maximum reduction of almost 23% compared to walking with the exosuit powered-off. To our knowledge, this is the highest relative reduction in energy expenditure observed to date with a tethered exoskeleton or exosuit.” Of course, assistive force wouldn’t be as helpful without an effective design. As Wired explains, the muscles and tendons from the hip to the knee need to work together in stabilizing the leg to achieve an efficient stride. So the researchers couldn’t stop with something that only covers the ankles — they had to use garters to connect the ankle straps to a hip girdle. The result is the exosuit’s current form, which you can see below. That said, the researchers admit that they need to conduct follow-up tests. For one, they had the subjects offload the exosuit’s cable-based actuation, electronics and battery units before conducting the experiment. Those make up an additional 17-plus pounds that would have changed the wearers’ situation. Further, they found that the subjects’ gaits changed depending on how much assistive force they provided, which was between 10 to 38 percent of the ankle force needed to take a step. They still need to explore the possibility that the reduction in energy is a result of the subjects’ change in gait rather than the assistive force itself. In the future, Harvard’s exosuit could help the elderly and patients suffering from Parkinson’s, cerebral palsy and other conditions to walk well on their own. As you can guess from that DARPA funding, though, it also has a potential military application: the agency hopes it can help soldiers carry heavy supplies far longer than they’d normally be able to.

9 planets where aliens could liveWhen NASA scientists announced…

9 planets where aliens could live When NASA scientists announced earlier this year that they had found evidence of liquid water on Mars, imaginations ran wild with the possibility that life could exist somewhere other than here on Earth. Scientists continue to explore the possibility that Mars once looked a lot like Earth — salty oceans, fresh water lakes, and a water cycle to go with it. That’s exciting stuff. So where else are they looking? What exactly are they looking for?
