We All Nearly Missed the Largest Underwater Volcano Eruption Ever Recorded

schwit1 quotes ScienceAlert: She was flying home from a holiday in Samoa when she saw it through the airplane window: a “peculiar large mass” floating on the ocean, hundreds of kilometres off the north coast of New Zealand. The Kiwi passenger emailed photos of the strange ocean slick to scientists, who realised what it was — a raft of floating rock spewed from an underwater volcano, produced in the largest eruption of its kind ever recorded. “We knew it was a large-scale eruption, approximately equivalent to the biggest eruption we’ve seen on land in the 20th Century, ” says volcanologist Rebecca Carey from the University of Tasmania, who’s co-led the first close-up investigation of the historic 2012 eruption. The incident, produced by a submarine volcano called the Havre Seamount, initially went unnoticed by scientists, but the floating rock platform it generated was harder to miss. Back in 2012, the raft — composed of pumice rock — covered some 400 square kilometres (154 square miles) of the south-west Pacific Ocean, but months later satellites recorded it dispersing over an area twice the size of New Zealand itself… for a sense of scale, think roughly 1.5 times larger than the 1980 eruption of Mount St. Helens — or 10 times the size of the 2010 Eyjafjallajokull eruption in Iceland. When an underwater robot first sent back detailed maps, one volcanologist remembers that “I thought the vehicle’s sonar was acting up… We saw all these bumps on the seafloor… It turned out that each bump was a giant block of pumice, some of them the size of a van.” Read more of this story at Slashdot.

AMD Is Releasing Spectre Firmware Updates To Fix CPU Vulnerabilities

An anonymous reader quotes a report from The Verge: AMD’s initial response to the Meltdown and Spectre CPU flaws made it clear “there is a near zero risk to AMD processors.” That zero risk doesn’t mean zero impact, as we’re starting to discover today. “We have defined additional steps through a combination of processor microcode updates and OS patches that we will make available to AMD customers and partners to further mitigate the threat, ” says Mark Papermaster, AMD’s chief technology officer. AMD is making firmware updates available for Ryzen and EPYC owners this week, and the company is planning to update older processors “over the coming weeks.” Like Intel, these firmware updates will be provided to PC makers, and it will be up to suppliers to ensure customers receive these. AMD isn’t saying whether there will be any performance impacts from applying these firmware updates, nor whether servers using EPYC processors will be greatly impacted or not. AMD is also revealing that its Radeon GPU architecture isn’t impacted by Meltdown or Spectre, simply because those GPUs “do not use speculative execution and thus are not susceptible to these threats.” AMD says it plans to issue further statements as it continues to develop security updates for its processors.

California is set to hit its green-energy goals a decade early

California is both the nation’s leading renewable-energy proponent and one of the few states to actually put its power where its mouth is. In November, the California Energy Commission released its annual Renewable Portfolio Standard (RPS) report which found that the state’s three investor-owned utilities — Pacific Gas & Electric, Southern California Edison and San Diego Gas & Electric — are on track to collectively offer 50 percent of their electricity from renewable resources by 2020. That’s a full decade faster than anyone had anticipated. Reports like these have been used to promote clean-energy production throughout the US and the rest of the world since the 1970s. However, it wasn’t until 2002 that California codified the practice . But despite being in effect for only 15 years, California’s mandatory reporting has become a potent tool in fighting greenhouse-gas emissions throughout the state. Arnold Schwarzenegger and CA Governor Jerry Brown at the One Planet Summit, Dec ’17 “We’ve got to realize that we are here today because of oil — oil and gas, to a lesser extent, coal, ” California Gov. Jerry Brown told the press at a 2015 signing ceremony, where he increased the state’s renewable goal to 50 percent. There, he pointed out that California is still the third-most-oil-producing state in the union, behind Texas and North Dakota. “What has been the source of our prosperity has become the source of our ultimate destruction, if we don’t get off of it, ” he added. And get off it we have. As of last year, 32.9 percent of PG&E’s power came from renewable resources, as did 28.2 percent from SoCal Edison and a whopping 43.2 percent from San Diego Gas — granted, SDG&E is by far the state’s smallest investor-owned utility. And, despite critics’ complaints that moving to renewables would stymie economic growth and increase the electric bills of customers throughout the state, it’s actually been quite the opposite. In the last seven years, California has seen a massive construction boom in the solar- and wind-energy sectors. The price of solar power has dropped to under $30 in 2016 from around $136 per megawatt-hour in 2008, while wind power prices have fallen to $51 in 2015 from $97 per megawatt-hour in 2007, per the report. Over the same period, the state has seen greenhouse-gas emissions from electricity generation decrease nearly every year. Jerry Brown speaks at the launch event at the US climate action center And despite the Trump administration’s quixotic quest to make coal happen, California has ratcheted up its own climate-change-response efforts. Of course, California isn’t the only state to do so. Hawaii recently passed legislation dictating that a full 100 percent of its electricity generation come from renewables by 2045, while Vermont is aiming to hit 75 percent by 2032. Granted, both of those states are home to far fewer people than California and therefore require far less energy, so the Golden State is uniquely situated to lead the renewable energy revolution. “California in a lot of ways is a blessed state, ” said Dr. Austin Brown, executive director of the UC Davis Policy Institute for Energy, Environment and Economy. “We have a wealth of both wind and solar, a lot of historically built hydro that we can use.” That said, California is not — and cannot be — in this effort alone. While the state does often produce an excess of solar power in the mornings and early afternoons, utilities often have to resort to gas-powered plants during the evening hours and during times of peak demand. As such, Brown explained, “hydropower is great because it can be used to fill in the peaks and valleys.” The Ivanpah Solar Electric Generating System “We have an interconnected grid so I think it would have been foolish to say, ‘It all has to be done in California, ‘” Brown continued. “One of the benefits of the grid is that we’re able to trade power — bring hydro down from the Northwest, bring wind in from Wyoming. These are all really good things.” California’s aggressive policies toward renewables also deserve credit. “People want to cast it as a choice between policy or technology as a solution but those should exist hand-in-hand, ” Brown said. “We would have never gotten renewable energy prices where they are today without really ambitious public policy.” Since 2002, both Gov. Brown and his Republican predecessor, Arnold Schwarzenegger, have continually sought to push the clean-energy standards forward. “It shows the importance of bold goals, ” Brown declared. “When you put a marker way out there and say, ‘We’re going to go achieve that, we’re going to write this down as a matter of policy and then go do it, ‘ you can accomplish an enormous amount.” And now that California is on pace to hit 50 percent renewable by 2020, the state could soon set an even loftier goal: 80 percent by 2050, according to Brown. “When you get it right, it’s this virtuous cycle where policy improves technology and that allows us to go for greater ambition without increasing prices and continuing to reduce unintended consequences, ” Brown said. Of course, setting goals and actually achieving them are two very different things. Indeed, the path to 80 percent renewables will pose its own unique challenges. The effects of diminishing returns will soon come into play, Brown explained. “Once we get to about 50 percent, we’re going to start to run into new challenges — the second 50 percent will be trickier than the first 50 percent.” Should we continually produce renewable energy at times when there is already excess generation, the value of that energy will decrease, Brown notes. Tesla Powerpack Units at the SoCal Edison Mira Loma Substation Yes, we could incorporate battery technology such as Tesla’s Power Cells or the 50 MW hybrid peaker plant system that installed this past April, but Brown thinks there might be an easier, less expensive alternative. “Storage is probably not the first option you want to talk about when you discuss grid integration just because batteries are still pretty expensive compared to other technologies, ” he said. Instead, Brown suggested methods such as pre-cooling buildings during times of low demand so as to not place additional strain on the grid during peak hours, or increasing grid flexibility — that is, increasing the ability to pass power around without congesting transmission lines. “When you look at it, storage works, but it’s probably the last thing in the stack that we want to go to, ” Brown concluded. The effects of global warming will pose their own unique set of challenges. With California’s temperate climate, residents don’t typically need to run their A/C or heaters for months on end as they do in other parts of the country, though that could change as the planet continues to warm. Daytime energy demands will likely increase throughout California and the Southwest due to the higher temperatures, thereby increasing air-conditioning usage, Brown explained. To a lesser degree, the colder winters should similarly increase heating demands. Brown also fears that we’ll see a “significant increase in heat-related injuries and death” as well as other dangerous trends such as the prolonged drought the state recently emerged from and the massive wildfires it currently faces. Burbank, California, residents fleeing the La Tuna Canyon Fire Energy production will also feel the impacts of climate change. “Solar is dependent on the amount of cloud cover, ” Brown said. “Wind power obviously depends on wind, and we might see shifting wind patterns in a changing climate, ” though he’s not entirely certain what those changing patterns will look like. Conventional power plants will also feel the effects. As Brown points out, a number of nuclear- and fossil-fuel plants have been temporarily knocked offline in the past few years because the of the heat that knocks their water-cooling systems offline. “It’s a threat multiplier, ” he said. “It takes all the things that are problematic now and makes them much more common.” And while achieving 100 percent renewable energy production is a noble goal, it may not be the most important one for California to focus on. “I think of 100 percent [renewable production] as a bit of a red herring, ” Brown explained. “If you want 100 percent it should be 100 percent zero-carbon electricity. Climate change is the existential threat, and I don’t want to waste time arguing about what’s renewable or not. You have to get the carbon out of the energy system as quickly as possible.” Images: Getty (All)

Renault’s concept EV drove me at 80MPH while I wore a VR headset

I’m driving the multimillion-dollar Symbioz EV concept on a highway in France when Renault-Nissan Senior VP Ogi Redzik hands me an Oculus VR headset. “Put it on. Do you see an image yet?” he asks me. “Not yet. Ahh, yes, now I see it, ” I reply nervously. A minute ago I was on a real road, but now I’m rolling down a fake forested highway in a simulation created by Ubisoft. Meanwhile, Renault’s Level 4 autonomous system has taken the piloting chores (with a professional, joystick-equipped driver backing it up in the passenger seat). It’s a bizarre experience, but I don’t feel sick, because the Symbioz is transmitting real road motion to the headset. That data is then subtly adjusting the virtual image to be in sync with the real-life car movements. I even see simulated versions of the cars and trucks on the road fed in by LiDAR and other sensors. After a few minutes, the headset shows a dramatic eclipse, and the faux Symbioz leaves the road and soars over a canopy of trees. All of this is part of the “mind off” driving experience that Renault is exploring with the Symbioz. With fully autonomous vehicles just around the corner, the company is trying to imagine how we can spend our free time once we surrender the wheel to robots. VR may not be your personal entertainment choice, but it exhibits that idea in a vivid way. “This demo really shows you that when your mind is off, it’s really off, ” Redzik told me. “If we give people back time, I don’t think we should be judging what they are going to use this time for, whether it’s gaming, VR or office work.” Renault sees future cars as more than just A-to-B transportation. As showcased during my tour of the concept, the Symbioz can drive into its own purpose-built house with a matching interior, sit on a special charging pad and backup your solar panels like a rolling PowerWall . With HiFi and video systems (supplied by Devialet and LG, respectively), it could even become a mini-room in your home for work or entertainment. Even the exterior of the Symbioz, dreamed up by Renault’s Senior Design VP Laurens van den Acker, is about the space inside. “The lines of the Symbioz demo car were designed to showcase the interior’s innovations, ” said Patrick Lecharpy, Renault-Nissan’s head of advanced design. The body, built with carbon-fiber panels and a metal chassis, has an extreme cab-forward design to maximize space and is low, long and very wide. The styling is an acquired taste, thanks to the weird mix of a low, curvy front end, and high, windowless, squared-off back. There is no tacked-on sensor array like you’ve seen on Waymo and other self-driving rigs. LiDAR units are hidden in the front headlight covers and rear bumper. Radar and ultrasonic sensors are placed inside the body, and a front camera is fitted at the top of the windshield. There’s also a rear camera hidden in the Renault logo, and side cameras cached in the door handles. AOL/Steve Dent Renault bravely invited me to drive its priceless EV, even though the weather in Normandy was, to use a local term, la merde . I was lucky enough to be on the first test flight; later in the day, only Renault’s drivers could take the wheel because of rain, sleet and hail conditions. We didn’t have to worry about getting wet or cold, though, as the Symbioz came to pick me up from inside its special little house. Once we were all seated, I could start to appreciate the interior design that accommodates all the embedded tech. As Lecharpy noted, inside is where the Symbioz really shines, with a futuristic but not too futuristic cabin befitting a road-going concept car. The driver and passengers get individual seats for safety and comfort. (The Symbioz mock-up shown in Frankfurt had front seats that could swivel into an Orient Express face-to-face seating configuration like Mercedes’ limited F 015 concept , but that was considered too dangerous for a car traveling at freeway speeds.) To maximize space and emphasize the “living room” idea, there is no center console or rear windshield. Nor are there physical mirrors, so rear-visibility is handled by a well-designed camera and display system. LG created the L-shaped OLED front console display and split infotainment touchscreen. It also developed the excellent heads-up display (HUD). Depending on the drive mode, the touchscreens change color to match the interior lighting. Even when the powerful sound system is cranked inside, folks outside the car can barely hear a thing. That’s because for its first car audio project, French HiFi company Devialet carefully considered the harmonics of the car’s body to reduce vibrations. Once I was acclimated, engineers detailed the route and explained how to use the three drive modes. During regular “classic” manual driving, the interior lighting is blue, and for “dynamic” mode, lights on the doors and OLED dash turn red. When you activate the auto drive (AD) setting by pushing two steering wheel buttons at once, everything becomes a champagne gold. The dashboard also displays different animations for each mode — all meant to give you instant visual cues about what the car is doing. If things went south during the auto-drive mode, I was instructed to do nothing and let the specially-trained driver in the front right seat, equipped with joystick controls, take over. He would then pass me back the controls in manual mode. (All of this was legal and approved by French authorities.) AOL The Symbioz rotated 180 degrees on its platform, the glass door opened, and I cautiously set off. After a few minutes getting used to its heft and width, I felt comfortable — or at least, as comfortable as possible while driving a multimillion-dollar, one-of-a-kind prototype. The EV is easy to maneuver thanks to a four-wheel-steering system — despite the 4.92-meter length (16.1 feet), it can turn on a dime. Once on the highway, the first step was to test “dynamic” manual driving. The Symbioz has a 72 kWh battery and produces 360 kW (483 horsepower), a bit less in both categories than Tesla’s P75D Model S. In standard mode power is limited to 160 kW, but the EV still accelerated quickly and could easily maintain freeway speeds. The handling and ride were smooth, but not exactly sporty. I found the LG’s OLED screens easy to read, even in direct sunlight. The GPS navigation system by TomTom worked well and displayed points of interest, charging stations, and other info. LG’s heads-up display was integrated seamlessly into the dash and floated ahead of the windshield in a natural, non-distracting way. It displayed essential information like the speed limit, current speed and turn-by-turn directions. Driving conditions were grim, alternating minute-by-minute between sunshine, rain, sleet and hail. Nevertheless, once established in the center of my freeway lane at 130km/h (80MPH), I pushed the two steering-wheel buttons with my thumbs to activate the auto-driving mode. This, I must add, was my first time using a fully-automatic self-driving vehicle (I tested Audi’s 2019 Level 3 Audi A8, but the Level 3 self-driving was disabled). At first, I was stuck behind a truck, so the Symbioz moved to overtake it. Unfortunately, the semi was spraying a flood of water and, unbeknownst to us, the right-hand headlight cover had fogged up, foiling the LiDAR unit inside. The AD subsequently disengaged with a bit of drama as the EV swerved from side to side. As instructed (and this was hard), I resisted touching the wheel, and the safety driver sat to my right quickly took over. After establishing control, he handed me back the wheel, and I quickly switched back to AD mode. This time, it kept things steady for a much longer period. Two GoPro cameras recorded all of these activities, as shown in the video above. Ubisoft With no need to guide the car, I slipped on the Oculus VR headset and followed Redzik’s instructions. Soon enough, I was immersed in Ubisoft’s simulation, rolling down a forested road and seeing a virtual version of the Symbioz cockpit and traffic around me. Next, there was a virtual eclipse, and the scene transformed into a nighttime cityscape. Finally, the virtual EV took flight, soaring over a dreamy, fog-filled forest. Though mildly worried, I was completely comfortable using the headset during the three-minute demo. VR is notorious for producing motion sickness even if you’re sitting still, but Ubisoft combines TomTom’s GPS road maps and the Symbioz’s acceleration data, feeding it all into the simulation. “The acceleration, the speed, the localization in the lanes, the lateral acceleration, everything is taken into account by the VR experience, ” said Mathieu Lips, director of the Symbioz demo car project. All of this is to avoid a perfect, vomitous storm of VR sickness and carsickness. “There is complete coherence between what you see on the screen, what your brain interprets and what your body is feeling [based on] what your inner ear interprets, ” Deborah Papiernik, senior VP at Ubisoft, told me. “And because there is perfect coherence in real time between the two, the experience is extremely comfortable.” That’s not even mentioning the insanity of putting on a VR headset while driving, but Renault wanted to make a strong statement about the “mind off” idea. “They wanted an experience that would provide escapism, that would allow the driver to let go, ” Papiernik explains. While you’re in your VR bliss, the Symbioz keeps reality intrusions to a minimum. Renault worked with French highway company SANEF to automate the process of going through a toll booth and even erected special WiFi towers along our route. “They have installed five antennas called ‘roadside units’ that use the 5.0 GHz long-range WiFi, ” Lips told me. “Those will inform the vehicles about which toll gates doors are open for autonomous driving.” When the Symbioz approaches a pay toll, it automatically heads to a lane that supports autonomous driving and wireless payment. It’s then supposed to slow to 30km/h (18MPH), transmit the payment, and pass the raised barrier without stopping. During my demo ride, the EV concept did find and squeeze into the narrow automatic payment lane. However, rather than cruising through, it had to execute a “stop and go” maneuver due to the brutal weather. It was still an impressive display of the tech’s potential, however. Renault During the drive, Renault gave me a demo of the AV system. As you’d expect, LG’s OLED dislay provided a bright, contrasty video-viewing experience, though I found the screen a bit too small. The sound from the Devialet audio system was clear and very loud, considering that it uses sound modules six times smaller than regular car speakers. All of that can be controlled by a special smartphone app, depending on the mode and where it detects that you are in the car. For instance, the driver won’t see anything on the main screen unless the Symbioz is in AD mode. Instead, it will only turn on video for the rear passengers. You can also control the climate, configuration of the car and other factors using the app. In the “Alone@home, ” mode, the dashboard and steering wheel retract, freeing up more space (this option wasn’t available in the real car, just a static display). “Relax” moves the seats to a “zero-gravity” reclined position, while “Lounge” lowers the armrests and turns you 10 degrees toward your passenger. Suffice to say, this is one complex car. “There is multiplicity of systems, complicated and innovative systems, which means a lot of interfaces between them, ” Lips explained. “And we only had one vehicle. The biggest challenge was to gather all this technology together into one unique [car].” But wait, there’s more The Symbioz is equipped with almost too much tech to mention in a single article, but here are a few other highlights. A fragrance dispenser with different odors depending on the driving mode. An LED sunroof that’s transparent in “classic” or auto-drive mode, but opaque in “dynamic” mode. An app that transmits travel and vehicle information to your smartphone twice, 15 and five minutes before you depart. Automatic “valet” parking. A future system that could push the dashboard up and retract the steering wheel to give you more interior space. “Zero gravity” seats that lay back nearly flat and a “lounge” mode that rotates them 10 degrees for more intimate proximity to seat-mates. Dynamic dashboard animations depending on the drive mode Sure, Renault’s Symbioz test drives were a smart PR move to bring attention to its electric and self-driving vehicle development. (Putting a VR experience into a Level 4 self-driving EV is a pretty well-played strategy for enticing tech journalists.) But Renault and its partners, Nissan and Mitsubishi, have an interesting story to tell. The alliance is looking at not just the technology for next-generation Leafs, Zoes and other green or autonomous cars, while also focusing on the driver experience. “The Symbioz is our early interpretation of how the new technologies related to autonomous and new experiences in a car will come to market, ” said Redzik. “We’re using this vehicle as an opportunity to learn … to find out how else you can engage with the vehicle when you’re not focused on driving.” By putting a VR headset on me in mid-drive, Renault showed that technology could make in-car entertainment comfortable and motion-sickness-free. At the same time, it forced me to confront the idea (and my fear) of AI completely taking over driving chores. AOL/Steve Dent Another thing that I realized while driving blind on the freeway? Before I’m ready to release control, I want both technical and physical proof that the systems are infallible. The problems we had with the inclement weather showed me that the systems are still a work in progress, though Renault assured me that better tech is around the corner. “For sure, the sensors will improve, ” said Lips. “There is a lot of progress going on that will allow the car to rely more on its sensors.” A lot of car companies like GM, Waymo and Uber have big plans about ride-sharing, carpooling and hailing services, and Renault is no doubt exploring that too. The last time I checked, though, most of us were still alone in our cars. The Symbioz does have a social aspect as a self-driving vehicle that can come into your house and entertain you and your family while you drive. But the most interesting part of it is what it can do for you when you’re alone. It’s clear that self-driving EVs, once we figure out the tech, will help the planet and make our roads safer. But Renault has taken that idea further with the Symbioz, combining autonomous tech with entertainment options like VR to create a rolling cocoon that gives us a brief detente in our information-overloaded lives. Rather than your commute being a kind of torture, it could become productive, a way to connect with yourself or get a moment to have a laugh, relax and be entertained. In other words, Renault has executed its vision of how self-driving cars may transform your A-to-B time-suck into one of the best parts of the day.

Ancient Tablet Reveals Babylonians Discovered Trigonometry

An anonymous reader quotes a report from Science Magazine: Trigonometry, the study of the lengths and angles of triangles, sends most modern high schoolers scurrying to their cellphones to look up angles, sines, and cosines. Now, a fresh look at a 3700-year-old clay tablet suggests that Babylonian mathematicians not only developed the first trig table, beating the Greeks to the punch by more than 1000 years, but that they also figured out an entirely new way to look at the subject. However, other experts on the clay tablet, known as Plimpton 322 (P322), say the new work is speculative at best. Consisting of four columns and 15 rows of numbers inscribed in cuneiform, the famous P322 tablet was discovered in the early 1900s in what is now southern Iraq by archaeologist, antiquities dealer, and diplomat Edgar Banks, the inspiration for the fictional character Indiana Jones. Now stored at Columbia University, the tablet first garnered attention in the 1940s, when historians recognized that its cuneiform inscriptions contain a series of numbers echoing the Pythagorean theorem, which explains the relationship of the lengths of the sides of a right triangle. (The theorem: The square of the hypotenuse equals the sum of the square of the other two sides.) But why ancient scribes generated and sorted these numbers in the first place has been debated for decades. Mathematician Daniel Mansfield of the University of New South Wales (UNSW) realized that the information he needed was in missing pieces of P322 that had been reconstructed by other researchers. He and UNSW mathematician Norman Wildberger concluded that the Babylonians expressed trigonometry in terms of exact ratios of the lengths of the sides of right triangles, rather than by angles, using their base 60 form of mathematics, they report today in Historia Mathematica.
