7:00a	Carbon Capture System Turns CO2 Into Electricity and Hydrogen Fuel Researchers at Ulsan National Institute of Science and Technology (UNIST) and Georgia Tech have developed a new system that absorbs carbon dioxide and produces electricity and useable hydrogen fuel. New Atlas reports: The new device, which the team calls a Hybrid Na-CO2 System, is basically a big liquid battery. A sodium metal anode is placed in an organic electrolyte, while the cathode is contained in an aqueous solution. The two liquids are separated by a sodium Super Ionic Conductor (NASICON) membrane. When CO2 is injected into the aqueous electrolyte, it reacts with the cathode, turning the solution more acidic, which in turn generates electricity and creates hydrogen. In tests, the team reported a CO2 conversion efficiency of 50 percent, and the system was stable enough to run for over 1,000 hours without causing any damage to the electrodes. Unlike other designs, it doesn't release any CO2 as a gas during normal operation -- instead, the remaining half of the CO2 was recovered from the electrolyte as plain old baking soda. The research was published in the journal iScience. Read more of this story at Slashdot. (Comment on this)
4:05p	Meizu Unveils a Smartphone That Does Not Have Any Port, or a SIM Card Slot, or a Button, or Speaker Grill Phone maker Meizu has announced a new phone called "Zero," which doesn't have a headphone jack, or a charging port, or a physical SIM card slot, or any buttons, or a speaker grill. From a report: It doesn't even come with a SIM card slot and buttons you'd usually see on a phone -- the only elements that disturb the surface of its all-display, 7.8mm-thick ceramic unibody are its 12MP and 20MP rear cameras and two pinholes. One is a microphone, while the other is for hard resets. To make up for the lack of ports, Meizu Zero will support Bluetooth 5.0 and a wireless USB connectivity that will reportedly be able to transfer files as fast as the USB 3.0 standard can. Zero's 5.99-inch QHD OLED screen will act as some sort of a giant speaker and earpiece replacement. It does have a big enough bezel for a 20MP front camera, but its fingerprint reader is completely on-screen. The device, which is powered by a Snapdragon 845 processor, relies on 18W wireless charging due to the lack of a charger port. And it may not have the usual physical buttons, but it does have pressure-sensing ones with haptic feedback on its borders. Read more of this story at Slashdot. (Comment on this)
11:10p	Twitter CEO Jack Dorsey Says Biometrics May Defeat Bots Trailrunner7 shares a report from Duo Security: From the beginning, Twitter's creators made the decision not to require real names on the service. It's a policy that's descended from older chat services, message boards and Usenet newsgroups and was designed to allow users to express themselves freely. Free expression is certainly one of the things that happens on Twitter, but that policy has had a number of unintended consequences, too. The service is flooded with bots, automated accounts that are deployed by a number of different types of users, some legitimate, others not so much. Many companies and organizations use automation in their Twitter accounts, especially for customer service. But a wide variety of malicious actors use bots, too, for a lot of different purposes. Governments have used bots to spread disinformation for influence campaigns, cybercrime groups employ bots as part of the command-and-control infrastructure for botnets, and bots are an integral part of the cryptocurrency scam ecosystem. This has been a problem for years on Twitter, but only became a national and international issue after the 2016 presidential election. Twitter CEO Jack Dorsey said this week that he sees potential in biometric authentication as a way to help combat manipulation and increase trust on the platform. "If we can utilize technologies like Face ID or Touch ID or some of the biometric things that we find on our devices today to verify that this is a real person, then we can start labeling that and give people more context for what they're interacting with and ideally that adds some more credibility to the equation. It is something we need to fix. We haven't had strong technology solutions in the past, but that's definitely changing with these supercomputers we have in our pockets now," Dorsey said. Jordan Wright, an R&D engineer at Duo Labs writes: "I think it's a step in the right direction in terms of making general authentication usable, depending on how it's implemented. But I'm not sure how much it will help the bot/automation issue. There will almost certainly need to be a fallback authentication method for users without an iOS device. Bot owners who want to do standard authentication will use whichever method is easiest for them, so if a password-based flow is still offered, they'd likely default to that." "The fallback is the tricky bit. If one exists, then Touch ID/Face ID might be helpful in identifying that there is a human behind an account, but not necessarily the reverse -- that a given account is not human because it doesn't use Touch ID," Wright adds.
