Japan To Build 250-Mile-Long, Four Storey-High Wall To Stop Tsunamis

An anonymous reader points out this daunting construction plan in Japan. “Japanese authorities have unveiled plans to build a giant 250-mile long sea barrier to protect its coastline from devastating tsunamis. According to the proposals, the £4.6bn ($6.8bn) barrier would reach 12.5m high in some places – stretching taller than a four storey building. It would be made out of cement – and actually be composed of a chain of smaller sea walls to make construction easier. The plan comes four years after a huge tsunami ravaged Japan’s north-eastern coast.” Read more of this story at Slashdot.

Stanford Breakthrough Could Make Better Chips Cheaper

angry tapir writes: Researchers at Stanford University have come up with a new way to make chips and solar panels using gallium arsenide, a semiconductor that beats silicon in several important areas but is typically too expensive for widespread use. “[I]t can cost about $5, 000 to make a wafer of gallium arsenide 8 inches in diameter, versus $5 for a silicon wafer, according to Aneesh Nainani, who teaches semiconductor manufacturing at Stanford. The new Stanford process (abstract) seeks to lessen this thousand-to-one cost differential by reusing that $5, 000 wafer. Today the working electronic circuits in a gallium arsenide device are grown on top of this wafer. Manufacturers make this circuitry layer by flowing gaseous gallium arsenide and other materials across the wafer surface. This material condenses into thin layer of circuitry atop the wafer. In this scenario, the wafer is only a backing. The thin layer of circuitry on top of this costly platter contains all of the electronics.” Read more of this story at Slashdot.

First Prototype of a Working Tricorder Unveiled At SXSW

the_newsbeagle writes The $10 million Tricorder X-prize is getting to the “put up or shut up” stage: The 10 finalists must turn in their working devices on June 1st for consumer testing. At SXSW last week, the finalist team Cloud DX showed off its prototype, which includes a wearable collar, a base station, a blood-testing stick, and a scanning wand. From the article: “The XPrize is partnering with the medical center at the University of California, San Diego on that consumer testing, since it requires recruiting more than 400 people with a variety of medical conditions. Grant Campany, director of the Tricorder XPrize, said he’s looking forward to getting those devices into real patients hands. ‘This will be a practical demonstration of what the future of medicine will be like, ‘ said Campany at that same SXSW talk, ‘so we can scale it up after competition.'” Read more of this story at Slashdot.

Bring On the Boring Robots

malachiorion writes: After a successful 6-month pilot, Savioke’s ‘butler bots’ are heading to hotels around the country. These are not sexy, scary, or even technically impressive machines. But they were useful enough, over the course of their 2, 000 or so deliveries, to warrant a redesign, and a larger deployment starting in April. Savioke’s CEO had some interesting things to say about the pilot, including the fact that some 95 percent of guests gave the robot a 5-star review, and only the drunks seemed to take issue with it. Plus, as you might expect, everyone seemed to want to take a damn selfie with it. But as small as the stakes might appear, highly specialized bots like this one, which can only do one thing (in this case, bring up to 10 pounds of stuff from the lobby to someone’s door) are a better glimpse of our future than any talk of hyper-competent humanoids or similarly versatile machines.

Apple Patents A Light-Splitting iPhone Camera Sensor System

Apple has secured a new patent (via AppleInsider) for a special three sensor camera designed for thin, wireless devices like the iPhone. The three sensors would each capture a separate color component, as divided by a special light-splitting cube that would divide up light entering the camera into red, green and blue (or other color set) wavelengths. Why? Better resolution and lower noise… Read More

Hack Air-Gapped Computers Using Heat

An anonymous reader writes Ben-Gurion University of the Negev (BGU) researchers have discovered a new method to breach air-gapped computer systems called “BitWhisper, ” which enables two-way communications between adjacent, unconnected PC computers using heat. BitWhisper bridges the air-gap between the two computers, approximately 15 inches apart that are infected with malware by using their heat emissions and built-in thermal sensors to communicate. It establishes a covert, bi-directional channel by emitting heat from one PC to the other in a controlled manner. Also at Wired. Read more of this story at Slashdot.

Costa Rica Goes 75 Days Powering Itself Using Only Renewable Energy

An anonymous reader writes with news about an impressive renewable energy accomplishment in Costa Rica. Costa Rica has achieved a clean energy milestone by using 100 per cent renewable energy for a record 75 days in a row. The feat was achieved thanks to heavy rainfall, which powered four hydroelectric plants in the first three months of the year, the state-run Costa Rican Electricity Institute said. No fossil fuels have been burnt to generate electricity since December 2014, in the state which is renowned for its clean energy policies.” Read more of this story at Slashdot.

Hundreds Expelled, Many Arrested, For Cheating In India’s School Exams

Etherwalk writes Sources conflict, but it looks like as many as 300 people have been arrested for cheating in the Indian state of Bihar after the Hindustan Times published images of dozens of men climbing the walls of a test center to pass answers inside. 500-700+ students were expelled and police had been bribed to look the other way. Xinhau’s version of the story omits any reference to police bribery, while The ABC’s omits the fact that police fired guns into the air. Read more of this story at Slashdot.
