Google and South Korean tech major LG are likely to skip the top tier Qualcomm Snapdragon 865 platform this year for their smartphones as the cost of the chipset is too high, a report claimed. From a report: The Pixel 5 and Pixel 5 XL don't actually use Qualcomm's flagship Snapdragon 865 as per the Android code base. Both are running the Snapdragon 765G, a chip that's one step down from the 865 in Qualcomm's lineup. There isn't actually a Snapdragon 865 Google phone in the Android repository, ArsTechnica reported on Monday. LG is taking a similar approach to its 2020 flagship, the LG G9 ThinQ: instead of shipping the Snapdragon 865, the company is also opting for the cheaper 765G, according to website Naver.

An anonymous reader quotes a report from Wired: Modern capitalism has never seen anything quite like the novel coronavirus SARS-CoV-2. In a matter of months, the deadly contagious bug has spread around the world, hobbling any economy in its path. [...] This economic catastrophe is blowing up the myth of the worker robot and AI takeover. We've been led to believe that a new wave of automation is here, made possible by smarter AI and more sophisticated robots. San Francisco has even considered a tax on robots -- replace a human with a machine, and pay a price. The problem will get so bad, argue folks like former presidential candidate Andrew Yang, we'll need a universal basic income to support our displaced human workers.

Yet our economy still craters without human workers, because the machines are far, far away from matching our intelligence and dexterity. You're more likely to have a machine automate part of your job, not destroy your job entirely. Moving from typewriters to word processors made workers more efficient. Increasingly sophisticated and sensitive robotic arms can now work side-by-side on assembly lines with people without flinging our puny bodies across the room, doing the heavy lifting and leaving the fine manipulation of parts to us. The machines have their strengths -- literally in this case -- and the humans have theirs. While robots can do the labor we don't want to do or can't do, such as lifting car doors on an assembly line, they're not very good at problem-solving. "Think about how you would pick up a piece of paper that's lying flat on a table. You can't grip it like you would an apple -- you have to either pinch it to get it to lift off the surface, or drag it to hang over the edge of the table," writes Matt Simon via Wired. "As a kid, you learn to do that through trial and error, whereas you'd have to program a robot with explicit instructions to do the same."

In closing, Simon writes: "Overestimating robots and AI underestimates the very people who can save us from this pandemic: Doctors, nurses, and other health workers, who will likely never be replaced by machines outright. They're just too beautifully human for that."

NASA needs 215 more petabytes of storage by the year 2025, and expects Amazon Web Services to provide the bulk of that capacity. However, the space agency didn't realize this would cost it plenty in cloud egress charges. As in, it will have to pay as scientists download its data. The Register reports: The data in question will come from NASA's Earth Science Data and Information System (ESDIS) program, which collects information from the many missions that observe our planet. NASA makes those readings available through the Earth Observing System Data and Information System (EOSDIS). To store all the data and run EOSDIS, NASA operates a dozen Distributed Active Archive Centers (DAACs) that provide pleasing redundancy. But NASA is tired of managing all that infrastructure, so in 2019, it picked AWS to host it all, and started migrating its records to the Amazon cloud as part of a project dubbed Earthdata Cloud. The first cut-over from on-premises storage to the cloud was planned for Q1 2020, with more to follow. The agency expects to transfer data off-premises for years to come.

NASA also knows that a torrent of petabytes is on the way. Some 15 imminent missions, such as the NASA-ISRO Synthetic Aperture Radar (NISAR) and the Surface Water and Ocean Topography (SWOT) satellites, are predicted to deliver more than 100 terabytes a day of data. We mention SWOT and NISAR because they'll be the first missions to dump data directly into Earthdata Cloud. The agency therefore projects that by 2025 it will have 247 petabytes to handle, rather more than the 32 it currently wrangles. NASA thinks this is all a great idea. And it will -- if NASA can afford to operate it. And that's a live question because a March audit report [PDF] from NASA's Inspector General noticed EOSDIS hadn't properly modeled what data egress charges would do to its cloudy plan. NASA "has not yet determined which data sets will transition to Earthdata Cloud nor has it developed cost models based on operational experience and metrics for usage and egress," the Inspector General's Office wrote. "As a result, current cost projections may be lower than what will actually be necessary to cover future expenses and cloud adoption may become more expensive and difficult to manage."

"Collectively, this presents potential risks that scientific data may become less available to end users if NASA imposes limitations on the amount of data egress for cost control reasons."

An anonymous reader quotes a report from The New York Times: Two years ago, the eCascadia [the electric version of the Freightliner Cascadia] was nothing more than a PowerPoint presentation -- a virtual rendering to expedite a diesel stalwart into a zero-emissions future for goods movement. Now it's one of several competing models, from start-ups as well as established truck makers, that are gearing up for production next year with real-world testing. Orders have poured in, from companies eager to shave operating costs and curb emissions, for trucks that won't see roads for months or even years. Volvo Trucks North America announced this year that it would test 23 of its VNR battery-electric heavy-duty trucks in and out of the Ports of Los Angeles and Long Beach. The Washington-based truck maker Kenworth is already there, operating the beginnings of Project Portal, a 10-truck fleet of semis powered with hydrogen fuel cells. And Daimler Trucks North America is making deliveries in 20 of its preproduction eCascadias with two partner companies, Penske Truck Leasing and NFI.

Medium- and heavy-duty trucks are responsible for about 8 percent of the country's greenhouse gas emissions, according to the Environmental Protection Agency. Electrics not only reduce tailpipe emissions to zero, they cost less to operate. With fewer moving parts, they are also easier to maintain. On average, it costs about $1.38 per mile to operate a diesel truck, according to the trucking information website TruckInfo.net; $70,000 of the $180,000 annual operating cost is fuel, and $15,000 goes toward maintenance. Tesla, by comparison, estimates its electric Semi will cost $1.26 per mile. Electric trucks do, however, cost more to buy upfront. While most manufacturers have yet to set pricing, the longer a truck's range, the more batteries it needs and the more it will cost.Tesla plans to sell its 300-mile-range Semi for $150,000 and 500-mile Semi for $180,000. The price of a new diesel tractor and trailer is about $150,000. [...] The electrification of trucking is rolling out in three distinct phases, starting with medium-duty box trucks and vans, followed by heavy-duty semis used for regional hauling, like the ones Volvo, Kenworth and Daimler are testing at Southern California's ports. "With battery vehicles, it comes down to range, because batteries cost money and they add weight," said Jim Mele, an analyst with Wards Intelligence. "Long haul will probably be the last to see electrification because they'll probably need fuel cells to get the range they need, and those are still in development."

An anonymous reader quotes a report from TechCrunch: In a great example of what can happen when smart, technically-oriented people come together in a time of need, an open-source hardware project started by a group including Irish entrepreneur Colin Keogh and Breeze Automation CEO and co-founder Gui Calavanti has produced a prototype ventilator using 3D-printed parts and readily available, inexpensive material. The ventilator prototype was designed and produced in just seven days, after the project spun up on Facebook and attracted participation from over 300 engineers, medical professionals and researchers.

The prototype will now enter into a validation process by the Irish Health Services Executive (HSE), the country's health regulatory body. This will technically only validate it for use in Ireland, which ironically looks relatively well-stocked for ventilator hardware, but it will be a key stamp of approval that could pave the way for its deployment across countries where there are shortages, including low-income nations. The group behind the ventilator also recently changed the focus of their Facebook community, renaming the group from the Open Source Ventilator Project to the Open Source COVID19 Medical Supplies community. They're looking at expanding their focus to finding ways to cheaply and effectively build and validate other needed equipment, including protective gear like masks, sanitizer and protective face guards for front-line healthcare workers.

One of the biggest new additions to Apple's new iPad Pro is a new "Light Detection and Ranging" (LIDAR) system on the rear camera, which Apple argued was the missing piece for revolutionary augmented reality applications. "It claims that by combining the depth information from the LIDAR scanner with camera data, motion sensors, and computer vision algorithms, the new iPad Pro will be faster and better at placing AR objects and tracking the location of people," reports The Verge. "But it doesn't change the fact that, right now, there still aren't a lot of compelling reasons to actually use augmented reality apps on a mobile device beyond the cool, tech-demo-y purposes that already exist." From the report: R apps on iOS today are a thing you try out once, marvel at how novel of an idea it is, and move on -- they're not essential parts of how we use our phones. And nearly three years into Apple's push for AR, there's still no killer app that makes the case for why customers -- or developers -- should care. Maybe the LIDAR sensor really is the missing piece of the puzzle. Apple certainly has a few impressive tech demos showing off applications of the LIDAR sensor, like its Apple Arcade Hot Lava game, which can use the data to more quickly and accurately model a living room to generate the gameplay surface. There's a CAD app that can scan and make a 3D model of the room to see how additions will look. Another demo promises accurate determinations of the range of motion of your arm.

The fact that Apple is debuting the iPad for AR doesn't help the case, either. While Apple has been rumored to be working on a proper augmented reality headset or glasses for years -- a kind of product that could make augmented digital overlays a seamless part of your day-to-day life -- the iPad (in 11-inch and 12.9-inch sizes) is effectively the opposite of that idea. It's the same awkwardness of the man who holds up an iPad to film an entire concert; holding a hardcover book-sized display in front of your face for the entire time you're using it just isn't a very natural use case.

It's possible that Apple is just laying the groundwork here, and more portable LIDAR-equipped AR devices (like a new iPhone or even a head-mounted display) are on their way in the future. Maybe the LIDAR sensor is the key to making more immersive, faster, and better augmented apps. Apple might be right, and the next wave of AR apps really will turn the gimmicks into a critical part of day-to-day life. But right now, it's hard not to look at Apple's LIDAR-based AR push as another hardware feature looking for the software to justify it.

Researchers from Intel and Cornell University trained a neuromorphic chip to learn and recognize the scents of 10 hazardous chemicals. Engadget reports: Using Intel's Loihi, a neuromorphic chip, the team designed an algorithm based on the brain's olfactory circuit. When you take a whiff of something, molecules stimulate olfactory cells in your nose. Those cells send signals to the brain's olfactory system, which then fires off electrical pulses. The researchers were able to mimic that circuitry in Loihi's silicon circuits. According to Intel, the chip can identify 10 smells, including acetone, ammonia and methane, even when other strong smells are present. And, Loihi learned each odor with just a single sample. That's especially impressive, the researchers say, because other deep learning techniques can require 3,000 times more training samples to reach the same level of accuracy. The work has been published in the journal Nature Machine Intelligence.

An anonymous reader quotes a report from Ars Technica: NFC is usually only used to for quick text transfers, like a tap-and-pay transaction at a register or a quick data transfer from an NFC sticker. A company called "Waveshare" is really pushing the limits of NFC, though, with a 7.5-inch e-ink display that gets its data, and its power, from an NFC transfer. The $70 display doesn't have a battery and doesn't need a wired power connection. E-paper (or e-ink) displays have the unique property of not needing power to maintain an image. Once a charge blasts across the display and correctly aligns pixels full of black and white balls, everything will stay where it is when the power turns off, so the image will stick around. You might not have thought about it before, but in addition to data, NFC comes with a tiny wireless power transfer. This display is designed so that NFC provides just enough power to refresh the display during a data transfer, and the e-ink display will hold onto the image afterward.

NFC data transfers max out at a whopping 424 kbit/s. While that's enough for an instant transfer of credit card data or a URL, the 800x400 image the display needs will take several seconds. Waveshare says the display takes five seconds just to refresh, and that doesn't count the data transfer, which will vary depending on how complex your image is. The video shows a start-to-finish refresh that takes 10 seconds. If you want to use a phone, an Android app will convert your image into several different black-and-white styles and beam it to the display. Sadly, there's no iOS app yet. iOS apps didn't have the ability to write to NFC devices for the longest time. Writing to NFC was added with the launch of iOS 13, which only happened a few months ago.

Now that Microsoft and Sony have published the technical specifications of their respective next-gen gaming consoles, we can compare them head-to-head to see which one has the edge. While Sony appears to lag behind Microsoft when it comes to specs, the PS5's speedy custom SSD may be its secret weapon. Engadget reports: Sony's lead PlayStation architect, Mark Cerny, finally gave us an in-depth look at the PS5 in a livestream event, in lieu of a major GDC keynote. [...] Cerny confirms that the PlayStation 5's graphics processor will feature 36 compute units and up to 10.28 teraflops worth of compute performance. That's a bit less than the Xbox Series X's 12-teraflop GPU, but realistically you might not see many differences in performance. There are plenty of other system optimizations, like the company's focus on a custom 825GB SSD, that'll be a huge leap over the PlayStation 4. That SSD will push 5.5 gigabytes per second compared to a mere 50 to 100 MB/s, meaning it can fill the system's 16GB of GDDR6 RAM in two seconds. And on the plus side, Sony will let you plug in a standard NVMe SSD to expand storage while Microsoft will rely on specialized 1TB SSD expansion cards.

Cerny was quick to point out that teraflop numbers are a "dangerous" way to measure absolute levels of performance. A teraflop from the PlayStation 5 translates to much more gaming performance than a teraflop from the PlayStation 4, thanks to the new console's more-efficient architecture. Still, it's not exactly unfair to compare the PS5 to the Xbox Series X, since both systems will be based on AMD's CPUs and GPUs. It's interesting to see how Sony and Microsoft devices take advantage of AMD's hardware. The PS5's eight-core Zen 2 CPU will run up to 3.5GHz with variable frequencies, so it can slow down when necessary. The Xbox Series X, meanwhile, will lock its Zen 2 processor at 3.8GHz, and devs can also choose to run their games at 3.6GHz with hyper threading. Sony also chose to use 36 RDNA 2 compute units running at up to 2.23GHz with a variable frequency while Microsoft stuffed its system with 52 compute units running at 1.825GHz. Cerny argues that running fewer cores at a higher frequency rate is more beneficial than running more cores at a lower rate, since it will lead to a speed bump across many GPU tasks.

Sony definitely has the lead with its custom SSD with 5GB/s of raw bandwidth and 8 to 9GB/s of compressed throughput. The Xbox Series X's SSD will be limited to 2.4GB/s of raw data and 4.8GB/s compressed. Again, while the numbers are significantly different, it's unclear how the performance will vary in real-world use. Microsoft also has a slightly higher GDDR6 memory bandwidth -- 10GB at 560GB/s and 6GB at 336GB/s -- than Sony's 448GB/s, which could make up for the slower storage. As for backwards compatibility, Sony announced that the PlayStation 5 will support PS4 and PS4 Pro games, but the company made no mention of retro PS1, PS2, and PS3 titles. Microsoft, on the other hand, stated that the Xbox Series X will support all games playable on the Xbox One, including those Xbox 360 and original Xbox console titles currently supported through backwards compatibility on the Xbox One.

According to The Associated Press and confirmed by The Wall Street Journal, General Motors, Ford, and Fiat Chrysler will shut down their factories for at least two weeks. "Meanwhile, Tesla appears to be defying officials in Alameda County, California -- the site of its only North American factory, in Freemont -- who have ordered Tesla to stop operations," reports Ars Technica. From the report: TechCrunch reports that a Wednesday email from the company's human resources department instructed employees to come to work. "We still do not have final word from the city, county, state and federal government on the status of our operations," the email said. "We have had conflicting guidance from different levels of government."

In an email published Tuesday by Eletrek, Tesla's head of HR argued that Tesla didn't need to shut down because the company counts as National Critical Infrastructure, as defined by the Department of Homeland Security. The category "includes auto manufacturing and energy infrastructure," according to Tesla. "People need access to transportation and energy, and we are essential to providing it," the email said. Tesla evidently believes that its interpretation of this DHS guidance supersedes the instructions of Alameda County officials to shut down. It remains to be seen if Alameda County officials agree. UPDATE: BuzzFeed News is reporting that Tesla will drop from around 10,000 employees to 2,500, following a shelter-in-place order announced on Monday in six counties in the San Francisco Bay Area. It's unclear when the scaleback will take place, or what the company is doing to prevent those workers from being infected with or spreading the virus.

Today, we get another diminutive desktop option, but this one is designed for Linux and privacy. From a report: Yes, Purism is finally launching a tiny desktop, and it will come pre-installed with the Debian-based PureOS. Called "Librem Mini," the cute bugger has 4 USB-A ports on the front, along with a 3.5mm audio jack, and the power button. On the rear, there are two more USB-A ports, a single USB-C port, Ethernet, HDMI, DisplayPort, and the power port. "Announcing the Purism Librem Mini. Our small form-factor mini-PC that puts freedom, privacy and security first. We're really excited about the Librem Mini, it's a device our community have wanted and we've wanted to offer for some time. The Librem Mini is accessible, small, light and powerful featuring a new 8th gen quad core i7 processor, up to 64 GB of fast DDR4 memory and 4k 60 fps video playback. It's a desktop for your home or oïfce, a media center for your entertainment, or an expandable home server for your files and applications," says Purism.

An anonymous reader shares a report from TechCrunch, written by Devin Coldewey: It's no secret I'm a fan of the reMarkable, a tablet with a paper-like display that's focused on text and sketching rather than rich media and games. The sequel to the original, announced today, looks to make a good thing even better. Designed for the creation and consumption of monochromatic content like long documents, e-books, notes and sketches, the reMarkable set itself apart as a more minimalist alternative (or complement) to the likes of the iPad or Surface. The device was crowdfunded and has sold more than 100,000 units; meanwhile, the company has grown and attracted a $15 million A round. One sees in retrospect that the money helped launch this successor.

The most obvious change is to the design. It has a bold asymmetrical look with a chrome band along the left side, indicating the tablet's main use as an alternative to a paper notebook: Hold it with your left hand and write with your right. Sorry, lefties. The new tablet is just 4.7 mm (0.19 in) thick, thinner than the iPad Pro and Sony's competing Digital Paper tablets, both of which are 5.9 mm. Let's be honest -- at these levels of thinness it's getting hard to tell the difference, but it's an accomplishment nevertheless. [...] The software running on the reMarkable has received several major updates since the product made its debut, adding things like handwriting recognition, a new interface, better performance and so on. But one of the most requested features is finally coming with the new device: saving articles from the web. The company is claiming a 3x boost to battery life, using the same 3,000 mAh battery, based on performance improvements throughout and a more efficient (but more powerful) dual-core ARM processor. That means two weeks of use and 90 days of standby. This is welcome news, because frankly the battery life and power management on the last one were not great. The reMarkable 2 will sell for $399 if you pre-order, and comes with a Marker and a folio case.

As countries affected by the coronavirus pandemic expect to run out of ventilators and other equipment, makers are desperately trying to fill the gap with proposals for open-source, do-it-yourself devices. From a report: Most cases of COVID-19 -- the disease caused by the novel coronavirus -- do not require hospitalization. But for people hospitalized with severe infections, coronavirus damages their lungs and makes it hard to breathe in and circulate the amount of oxygen that their bodies need. Ventilators, machines that provide the lungs with oxygen, are proving to be key to treating these people, who seem to comprise around 10 percent of cases. Governments are already preparing for what a shortage of ventilators could do to their health care systems.

In a call to U.S. governors on Monday that was shared with The New York Times, President Donald Trump told states not to rely fully on the federal government for equipment. "Respirators, ventilators, all of the equipment -- try getting it yourselves," he said, according to The Times. "We will be backing you, but try getting it yourselves. Point of sales, much better, much more direct if you can get it yourself." Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, said on CNN that the U.S. has stockpiled 12,700 ventilators, but in a worst-case scenario that number might not be enough. In Italy, he added, physicians are having to make "very tough decisions" about whom to treat.

MojoKid writes: Though Ryzen 4000 Series laptop processors aren't available just yet, some of AMD's partners are going to begin taking pre-orders for notebooks soon. As such, AMD is lifting the veil on additional details and the architectural enhancements that make Ryzen 4000 Series AMD's strongest mobile processor line-up to date. AMD Ryzen 4000 series CPUs are based on the Zen 2 architecture, similar to the current Ryzen 3000 series desktop processors. AMD is touting an approximate 25% IPC increase versus Zen 1-based mobile parts, but there are additional benefits that boost performance and efficiency throughout the chips as well. These are monolithic SoCs, with up to 8-cores / 16-threads, that are manufactured on TSMC's 7nm node. AMD is claiming 20% lower SoC power, 2X the perf-per-watt, 5X faster state switching, and an approximate 3.4X improvement in relative power efficiency, in comparison to its mobile platform from 2015. AMD is claiming superior single-thread CPU performance versus current-generation Intel mobile processors and significantly better multi-threaded and graphics performance versus Intel, thanks to the increased core / thread counts and integrated Vega-based GPU of its Ryzen 4000 series. Battery life performance is claimed be strong as well, due to architectural enhancements for power optimization throughout the Ryzen 4000 design. AMD Ryzen 4000 Series laptops should be shipping in market sometime in the next month or so.

Apple's A14 processor that's expected to debut this fall in Apple's iPhone 12 models is rumored to have a frequency reaching 3.1GHz. "This would be 400MHz higher than Apple's current A13 Bionic chip with a frequency of 2.7GHz," reports MacRumors. From the report: At such a frequency, the chip's Geekbench 5 running points have surged. The report mentions that the A14's single-core performance shows a score of 1658 (up 25% from the A13), and a multi-core score of 4612 points (up 33% from the A13). The extra processing power will be helpful in running simultaneous workflows, navigating through apps, and more. Apple chipmaker TSMC is expected to ramp up production of Apple's 5nm-based A14 chipsets in as early as April of this year. Also, according to 9to5Mac, Apple is reportedly planning to launch a new 5.5-inch entry-level iPhone with a solid state home button, Touch ID, and support for Apple Pay's Express Transit feature.

The 5.5-inch iPhone is expected to be priced $100 more than the 4.7-inch model that will start at $399, according to Apple analyst Ming-Chi Kuo. It's slated to launch at the end of March, but it's possible the launch will be delayed due to the coronavirus.

Volkswagen's chief strategist Michael Jost predicts their vehicle-to-grid electric car batteries could open up a new business opportunity: selling their electricity back to the power grid during peak demand. Reuters reports: "By 2025 we will have 350 gigawatt hours worth of energy storage at our disposal through our electric car fleet. Between 2025 and 2030 this will grow to 1 terawatt hours worth of storage," Jost told journalists in Berlin. "That's more energy than is currently generated by all the hydroelectric power stations in the world. We can guarantee that energy will be used and stored and this will be a new area of business."

The German carmaker is not alone in looking into this field. German utility E.ON has been working with Japanese carmaker Nissan to develop so-called vehicle-to-grid services.

"We don't often talk about power supplies, but Intel's new ATX12VO spec — that's an 'O' for 'Oscar,' not a zero — will start appearing soon in pre-built PCs from OEMs and system integrators, and it represents a major change in PSU design," reports PC World.

"The ATX12VO spec removes voltage rails from the power supply, all in a bid to improve efficiency standards on the PC and meet stringent government regulations. But while the spec essentially removes +3.3-volt, +5-volt and -12-volt and +5-volt standby power from the PSU, they aren't going away — they're just moving to the motherboard. That's the other big change..."

Long-time Slashdot reader UnknowingFool explains: If those voltages are required, the motherboard is expected to supply it by converting 12V power. Removing those two rails will shrink the connector from 24 pin to 10 pin.

One of the main reasons is increased flexibility for future needs. That dependence on these separate rails has been reduced over time but current power supplies must dedicate a fixed amount to those rails. The example given is that a current 600W PS may only need 15% (90W) of total power dedicated to those rails but a decade ago may require 25% (150W). Switching to the MB supplying the power means more 12V power.

A benefit is power supplies will be cheaper to make and also more power efficient. With two fewer rails, there is fewer connectors and parts and power supply makers can focus on efficiency of just one rail.

After years of civil war, South Sudan is beginning to build the nation's electric sector from the ground up. "With only a handful of oil-fired power plants and crumbling poles and wires in place, the country is striving for a system that runs primarily on renewable energy and reaches more homes and businesses," reports IEEE Spectrum. From the report: Today, only about 1 percent of South Sudan's 12.5 million people can access the electric grid, according to the state-run utility. Many people use rooftop solar arrays or noisy, polluting diesel generators to keep the lights on; still many more are left in the dark. Those who can access the grid must pay some of the highest electricity rates in the world for a spotty and unreliable service. Recently, development banks and foreign companies have started backing projects to revitalize infrastructure and boost power generation amid a relatively tranquil time for the eight-year-old country. Most of the new investment has focused in and around Juba -- the nation's capital and largest city, with some 403,000 residents.

The work to restore South Sudan's electric sector began in earnest in late 2018, after South Sudan's President Salva Kiir reached a peace deal with rebel leader Riek Machar. (Earlier this year, Kiir appointed Machar as vice president.) Last November, South Sudan Electricity Corporation began operating the first section of Juba's rehabilitated distribution network. Power Construction Corporation of China strung up new 33-kilovolt lines, replacing the city's 11-kilovolt lines, a network that will eventually supply 20,000 additional customers in the capital city. The Chinese firm is also producing 13,450 prestressed concrete poles from a new facility in Juba. The African Development Bank has approved a US $14.6 million loan for the grid project. For now, however, most of Juba's residents are still using their own power supplies to run refrigerators or charge computers. The utility dismantled the old grid, and the upgraded system is proceeding slowly in phases.

A team of scientists led by Yi Cui, a materials scientist at Stanford, have created a new "fireproof" solid-state electrolyte for use in lithium-ion batteries. IEEE Spectrum reports: They used a flame-retardant material called decabromodiphenyl ethane, or DBDPE for short. To make their new solid-state electrolyte, the team first created a thin film by combining DBDPE with polyimide, a mechanical enforcer. Using polyimide has many advantages, says Wan. Apart from being "mechanically really strong," it boasts a high melting point (making it less likely that a short circuit will occur), a solutions-based manufacturing process (that's compatible with how batteries are made today), and it's inexpensive (3M even has film tapes made from it). The hitch, however, is that polyimide can't conduct ions. To get around this snag, Wan and his colleagues added two different polymers, polyethylene oxide (PEO) and lithium bistrifluoromethanesulfonylimide (LiTFSI), to the mix. "It's innovative -- they've smartly used co-polymers, which is a new way to solve the flammable polymer electrolyte battery problem," says Chunsheng Wang, a researcher who studies new battery technologies at the University of Maryland. The paper has been published in the journal Nano Letters.

Europe and Russia have decided to push back the launch of their joint robotic rover to Mars until 2022, rather than launch this year as originally planned. More testing is needed on the vehicle's parachutes ahead of the launch, according to the European Space Agency (ESA), and there isn't enough time to get all of that work done before the launch window in July and August. The Verge reports: This is the second major delay for the rover, which is a critical piece of the ExoMars mission -- a partnership program between ESA and Russia's state space corporation Roscosmos aimed at figuring out if Mars ever hosted life. Originally, the rover, named after the famous chemist Rosalind Franklin, was meant to launch in 2018, but it was pushed until 2020 due to delays in delivering the scientific payloads. Now, the parachutes needed to land the vehicle on Mars are to blame. Last year, two high-altitude drop tests here on Earth damaged the parachutes, with some even tearing while they inflated. ESA wants to do two additional parachute tests ahead of the mission, but they won't occur in time to allow a summer launch to happen.

Additionally, some of the electronics inside the vehicle that carries the rover down to the surface need to be returned to their suppliers for troubleshooting. The final software for the mission is also delayed, and engineers don't have enough time to test it out before the summer. And if that wasn't enough, Jan Worner, the director general of ESA, admitted that the ongoing novel coronavirus pandemic is playing a role in the delay. [...] Now, the earliest option to launch the Rosalind Franklin rover is 2022, thanks to how Earth and Mars orbit the Sun. The two planets only skim close by one another every 26 months, giving scientists a limited window to launch spacecraft to the Red Planet. With a launch window opening up this summer, multiple countries including the US, China, and the United Arab Emirates are launching spacecraft to Mars. But since ExoMars cannot make the deadline, the next opportunity to launch is between August and October 2022.

While ESA and Roscosmos wait for 2022, the rover will go into storage, and engineers will lubricate the vehicle over the next two years to maintain all of its components. In the meantime, the Russian Proton rocket that will launch the rover and the vehicle's European carrier spacecraft are all ready to go and have no issues. So the Rosalind Franklin rover should be ready to go by 2022 if the upcoming tests go well.
