Slashdot's new-record department:
A study published in the journal eLife describes three participants that broke new ground in the use of brain-computer interfaces (BCIs) by people with paralysis. One of the participants, a 64-year-old man paralyzed by a spinal cord injury, "set a new record for speed in a 'copy typing' task," reports IEEE Spectrum. "Copying sentences like 'The quick brown fox jumped over the lazy dog,' he typed at a relatively blistering rate of eight words per minute." From the report: This experimental gear is far from being ready for clinical use: To send data from their implanted brain chips, the participants wear head-mounted components with wires that connect to the computer. But Henderson's team, part of the multiuniversity BrainGate consortium, is contributing to the development of devices that can be used by people in their everyday lives, not just in the lab. "All our research is based on helping people with disabilities," Henderson tells IEEE Spectrum. Here's how the system works: The tiny implant, about the size of a baby aspirin, is inserted into the motor cortex, the part of the brain responsible for voluntary movement. The implant's array of electrodes record electrical signals from neurons that "fire" as the person thinks of making a motion like moving their right hand -- even if they're paralyzed and can't actually move it. The BrainGate decoding software interprets the signal and converts it into a command for the computer cursor. Interestingly, the system worked best when the researchers customized it for each participant. To train the decoder, each person would imagine a series of different movements (like moving their whole right arm or wiggling their left thumb) while the researchers looked at the data coming from the electrodes and tried to find the most obvious and reliable signal. Each participant ended up imagining a different movement to control the cursor. The woman with ALS imagined moving her index finger and thumb to control the cursor's left-right and up-down motions. Henderson says that after a while, she didn't have to think about moving the two digits independently. "When she became facile with this, she said it wasn't anything conscious; she felt like she was controlling a joystick," he says. The man with the spinal cord injury imagined moving his whole arm as if he were sliding a puck across a table. "Each participant settled on control modality that worked best," Henderson says.

Slashdot's sigh-of-relief department:
An anonymous reader quotes a report from The Verge: Cats host a parasite called Toxoplasma gondii that other research has linked to various mental illnesses. So, for some time, people have wondered whether cats are unsafe; for example, pregnant women are usually told to stay away from litter boxes. (They should still do this because transmission during pregnancy is very real.) In a study published in the journal Psychological Medicine, researchers looked at data that tracked 5,000 Brits born in the early '90s until they were 18. This included information about whether the kids grew up with cats, or whether there were cats around when the mother was pregnant. After the scientists controlled for factors like socioeconomic status, there was no link between developing psychosis and having owned a cat. The researchers suggest that previous studies that did show a link had relatively small sample sizes. In addition, many of these studies asked people whether they remembered having cats, which is not quite as accurate. That said, it's important to keep in mind that some mental disorders linked to the parasite -- like schizophrenia -- tend to be diagnosed fairly late in life, so only tracking until age 18 might limit the study.

An anonymous Slashdot reader shares a report from BGR: Tesla on Wednesday released its earnings report (PDF) for the company's recent fourth quarter. When the dust settled, Tesla posted revenue of $2.28 billion and a loss of 69 cents per share. By way of contrast, Tesla during the same quarter a year-ago posted a loss of $0.87 per share on the back of $1.75 billion in revenue. Notably, Tesla notes that its cumulative 2016 revenue checked in at $7 billion, a 73% increase from 2015. As far as the Model 3 is concerned, Tesla's press release relays that the company is still on track to begin production in July ahead of volume production in September. Tesla notes in its press release: "Our Model 3 program is on track to start limited vehicle production in July and to steadily ramp production to exceed 5,000 vehicles per week at some point in the fourth quarter and 10,000 vehicles per week at some point in 2018. To support accelerating vehicle deliveries and maintain our industry-leading customer satisfaction, we are expanding our retail, Supercharger, and service functions. Model 3 vehicle development, supply chain and manufacturing are on track to support volume deliveries in the second half of 2017. In early February, we began building Model 3 prototypes as part of our ongoing testing of the vehicle design and manufacturing processes. Initial crash test results have been positive, and all Model 3-related sourcing is on plan to support the start of production in July. Installation of Model 3 manufacturing equipment is underway in Fremont and at Gigafactory 1, where in January, we began production of battery cells for energy storage products, which have the same form-factor as the cells that will be used in Model 3."

At CP+2017, Sony announced the SF-G UHS-II SD card that features read and write speeds of 300MB/s and 299 MB/s, respectively, which makes it the fastest SD card in the world. Amateur Photographer reports: Available in 32GB, 64GB or 128GB from March 2017, all versions of the cards are compatible with Sony's free file rescue software, for recovering lost content. Pricing has yet to be revealed. Alongside the SF-G series, Sony has also introduced a new memory card reader, the MRW-S1, due for release in April. It features an in-built SuperSpeed USB port for cable-free PC connection, so that your files can be copied faster than by using the slower SD slot on a PC. [From the press release:] "'As the continuous shooting of higher-resolution images and adoption of 4K video with DSLR and mirrorless camera increases, the inherent need for larger, faster and more reliable cards becomes apparent. Thanks to the SF-G series, we continue to show our commitment to providing a full range of extremely high performance media devices to professional photographers and enthusiasts, maximizing their camera performances,' said Romain Rousseau, European Product Marketing Manager."

An anonymous reader quotes a report from Ars Technica: Apple has been building its giant new "spaceship" campus in the company's hometown of Cupertino, California, since December of 2013, and since then fans have paid obsessive attention to the structure. It gets buzzed by drones constantly, and the most popular YouTube videos of the building in progress have amassed well over half-a-million views apiece. The company announced today that the campus will be open to employees starting in April and that the building and environs now have a name: Apple Park. Apple says that moving the 12,000 employees who will work at the campus will take more than six months, and landscaping and construction on some buildings won't be done until the summer. The new campus mostly replaces the university-style Infinite Loop campus Apple has used since 1993, though Apple has said that it will also be keeping the older buildings. The new campus' cost has been estimated at around $5 billion. Apple will also be naming one space on the new campus after its founder and former CEO -- the Steve Jobs Theater will replace the current Town Hall event space that Apple sometimes uses for company meetings and product announcements, and it will open "later this year." The new space will be much larger (it will seat 1,000, compared to roughly 300 for the Town Hall), and the larger space will presumably allow Apple to launch more of its products on its campus rather than having to rent expensive event space in downtown San Francisco. The company is also moving its Worldwide Developers Conference closer to home this year -- it will return to San Jose after many years at the Moscone Center in San Francisco.

Slashdot's breakthrough department:
At a press conference on Wednesday, NASA scientists announced that they have spotted seven Earth-sized planets orbiting closely around a small, ultra-cool star. The star is 39 light years away. From a report on The Guardian: It is the first time that so many Earth-sized planets have been found in orbit around the same star, an unexpected haul that suggests the Milky Way may be teeming with worlds that, in size and firmness underfoot at least, resemble our own rocky home. The planets closely circle a dwarf star named Trappist-1, which at 39 light years away makes the system a prime candidate to search for signs of life. Only marginally larger than Jupiter, the star shines with a feeble light about 2,000 times fainter than our sun. "The star is so small and cold that the seven planets are temperate, which means that they could have some liquid water and maybe life, by extension, on the surface," said Michael Gillon, an astrophysicist at the University of Liege in Belgium. [...] While the planets have Earth-like dimensions, their sizes ranging from 25 percent smaller to 10 percent larger, they could not be more different in other features. Most striking is how compact the planet's orbits are. Mercury, the innermost planet in the solar system, is six times farther from the sun than the outermost seventh planet is from Trappist-1.

An anonymous reader shares a Fortune report: General Electric will put cameras, microphones, and sensors on 3,200 street lights in San Diego this year, marking the first large-scale use of "smart city" tools GE says can help monitor traffic and pinpoint crime, but raising potential privacy concerns. Based on technology from GE's Current division, Intel and AT&T, the system will use sensing nodes on light poles to locate gunshots, estimate crowd sizes, check vehicle speeds and other tasks, GE and the city said on Wednesday. The city will provide the data to entrepreneurs and students to develop applications. Companies expect a growing market for such systems as cities seek better data to plan and run their operations. San Diego is a test of "Internet of things" technology that GE Current provides for commercial buildings and industrial sites.

Reader MojoKid writes: AMD CEO, Dr. Lisu Su took to the stage at AMD's Ryzen tech day yesterday and opened the event with official speeds, feeds, pricing, and benchmark scores for the company's upcoming Ryzen series processors. AMD's goal with Ryzen, which is based on its Zen microarchitecture, was a 40% IPC (instructions per clock) uplift. As it turns out, AMD was actually able to increase IPC by approximately 52% with the final shipping product, sometimes more depending on workload type. Dr. Su also showed the first die shot of an 8-core Ryzen processor, disclosing that it consists of approximately 4.8 billion transistors. AMD's flagship Ryzen 7 1800X 8-core/16 thread CPU will have a base clock speed of 3.6GHz, a boost clock of 4.0GHz, and a 95 watt TDP. AMD claims the Ryzen 7 1800X will be the fastest 8-core desktop processor on the market when it arrives. The next member of the line-up is the Ryzen 7 1700X with a base clock of 3.4GHz and a boost clock of 3.8GHz, also with 8 cores and a 95 watt TDP. Finally, the Ryzen 7 1700 – sans X – is also an 8-core / 16-thread CPU, but it has lower 3.0GHz base and 3.7GHz boost clocks, along with a lower 65 watt TDP. AMD took the opportunity to demo the Ryzen 7 1800X and it was approximately 9% faster than the Core i7-6900K running Cinebench R15's multi-threaded test, at about half the cost. And in another comparison, Dr. Su put the 8-core 7 1700 up against the quad-core Core i7-7700K, converting a 4K 60 FPS video down to 1080P and the Ryzen CPU outpaces the Core i7 by 10 full seconds. Pricing for the three initial Ryzen 7 series processors will undercut competing Intel processors significantly. AMD's Ryzen 7 1800X will arrive at $499, Ryzen 7 1700X at $399, and Ryzen 7 1700 at $329. Based on current street prices, Ryzen will be between 20% — 50% lower priced but AMD is claiming performance that's better than Intel at those price points.

Almost two months to the day after Uber loaded its fleet of self-driving SUVs into the trailer of a self-driving truck and stormed off to Arizona in a self-driving huff, the company is preparing to launch its second experiment (if you don't count the aborted San Francisco pilot) in autonomous ride-hailing. From a report on The Verge: What's different is that this time, Uber has the blessing from Arizona's top politician, Governor Doug Ducey, a Republican, who is expected to be "Rider Zero" on an autonomous trip along with Anthony Levandowski, VP of Uber's Advanced Technologies Group. [...] Starting today, residents of Tempe, Arizona, can hail a self-driving Volvo XC90 SUV on Uber's ride-sharing platform. All trips will include two Uber engineers in the front seats as safety drivers, in the event a human needs to take over control from the vehicle's software. Uber says it hopes to expand the coverage area to other cities in Arizona in the coming weeks.

BrianFagioli quotes a report from BetaNews: Today, Google unveiled yet another way to share files. Called "Upspin," the open source project aims to make sharing easier for home users. With that said, the project does not seem particularly easy to set up or maintain. For example, it uses Unix-like directories and email addresses for permissions. While it may make sense to Google engineers, I am dubious that it will ever be widely used. "Upspin looks a bit like a global file system, but its real contribution is a set of interfaces, protocols, and components from which an information management system can be built, with properties such as security and access control suited to a modern, networked world. Upspin is not an "app" or a web service, but rather a suite of software components, intended to run in the network and on devices connected to it, that together provide a secure, modern information storage and sharing network," says Google. The search giant adds: "Upsin is a layer of infrastructure that other software and services can build on to facilitate secure access and sharing. This is an open source contribution, not a Google product. We have not yet integrated with the Key Transparency server, though we expect to eventually, and for now use a similar technique of securely publishing all key updates. File storage is inherently an archival medium without forward secrecy; loss of the user's encryption keys implies loss of content, though we do provide for key rotation."
