Researchers from the University Hospital Zurich, ETH Zurich, Wyss Zurich and the University of Zurich have developed a machine that repairs injured human livers and keeps them alive outside the body for one week. ScienceDaily reports: Until now, livers could be stored safely outside the body for only a few hours. With the novel perfusion technology, livers -- and even injured livers -- can now be kept alive outside of the body for an entire week. This is a major breakthrough in transplantation medicine, which may increase the number of available organs for transplantation and save many lives of patients suffering from severe liver disease or a variety of cancers. Injured cadaveric livers, initially not suitable for use in transplantation, may regain full function while perfused in the new machine for several days. The basis for this technology is a complex perfusion system, mimicking most core body functions close to physiology. The corresponding study was published in the journal Nature Biotechnology.

The inaugural study shows that six of ten perfused poor-quality human livers, declined for transplantation by all centers in Europe, recovered to full function within one week of perfusion on the machine. The next step will be to use these organs for transplantation. The proposed technology opens a large avenue for many applications offering a new life for many patients with end stage liver disease or cancer.

Google is working to improve the speed and security of on-device AI through a little-known initiative called Coral. The Verge reports: "Traditionally, data from [AI] devices was sent to large compute instances, housed in centralized data centers where machine learning models could operate at speed," Vikram Tank, product manager at Coral, explained to The Verge over email. "Coral is a platform of hardware and software components from Google that help you build devices with local AI -- providing hardware acceleration for neural networks ... right on the edge device." To meet customers' needs Coral offers two main types of products: accelerators and dev boards meant for prototyping new ideas, and modules that are destined to power the AI brains of production devices like smart cameras and sensors. In both cases, the heart of the hardware is Google's Edge TPU, an ASIC chip optimized to run lightweight machine learning algorithms -- a (very) little brother to the water-cooled TPU used in Google's cloud servers.

While its hardware can be used by lone engineers to create fun projects (Coral offers guides on how to build an AI marshmallow-sorting machine and smart bird feeder, for example), the long-term focus, says Tank, is on enterprise customers in industries like the automotive world and health care. Although Coral is targeting the world of enterprise, the project actually has its roots in Google's "AIY" range of do-it-yourself machine learning kits, says Tank. Launched in 2017 and powered by Raspberry Pi computers, AIY kits let anyone build their own smart speakers and smart cameras, and they were a big success in the STEM toys and maker markets. Tank says the AIY team quickly noticed that while some customers just wanted to follow the instructions and build the toys, others wanted to cannibalize the hardware to prototype their own devices. Coral was created to cater to these customers. The Coral team says it's trying to differentiate itself from the competition by tightly integrating its hardware with Google's ecosystem of AI services. "Coral is so tightly integrated with Google's AI ecosystem that its Edge TPU-powered hardware only works with Google's machine learning framework, TensorFlow, a fact that rivals in the AI edge market The Verge spoke to said was potentially a limiting factor," the report says.

"Coral products process specifically for their platform [while] our products support all the major AI frameworks and models in the market," a spokesperson for AI edge firm Kneron told The Verge. (Kneron said there was "no negativity" in its assessment and that Google's entry into the market was welcome as it "validates and drives innovation in the space.")

Cy Guy writes: Having not learned the lessons of Jurassic Park and the Terminator, scientists from the University of Vermont and Tufts have created "reconfigurable organisms" using stem cells from frogs. But don't worry, the research was funded by the Department of Defense, so I'm sure nothing could possibly go wrong this time. "The robots, which are less than 1mm long, are designed by an 'evolutionary algorithm' that runs on a supercomputer," reports The Guardian. "The program starts by generating random 3D configurations of 500 to 1,000 skin and heart cells. Each design is then tested in a virtual environment, to see, for example, how far it moves when the heart cells are set beating. The best performers are used to spawn more designs, which themselves are then put through their paces."

"Because heart cells spontaneously contract and relax, they behave like miniature engines that drive the robots along until their energy reserves run out," the report adds. "The cells have enough fuel inside them for the robots to survive for a week to 10 days before keeling over."

The findings have been published in the Proceedings of the National Academy of Sciences.

An anonymous reader quotes a report from IEEE Spectrum: Busan-based firm Jenax has spent the past few years developing J.Flex, an advanced lithium-ion battery that is ultra-thin, flexible, and rechargeable. With the arrival of so many wearable gadgets, phones with flexible displays, and other portable gizmos, "we're now interacting with machines on a different level from what we did before," says EJ Shin, head of strategic planning at Jenax. "What we're doing at Jenax is putting batteries into locations where they couldn't be before," says Shin. Her firm demonstrated some of those new possibilities last week at CES 2020 in Las Vegas.

The devices shown by Jenax included a sensor-lined football helmet developed by UK-based firm HP1 Technologies to measure pressure and force of impact; a medical sensor patch designed in France that will be embedded in clothing to monitor a wearer's heart rate; and wearable power banks in the form of belts and bracelets for patients who must continuously be hooked up to medical devices. To make batteries flexible, companies play around with the components of a battery cell, namely the cathode, anode, electrolyte, and membrane separator. In the case of Jenax, which has more than 100 patents protecting its battery technology, Shin says the secret to its flexibility lies in "a combination of materials, polymer electrolyte, and the know-how developed over the years." J.Flex is made from graphite and lithium cobalt oxide, but its exact composition and architecture remains a secret. "J.Flex can be as thin as 0.5 millimeters (suitable for sensors), and as tiny as 20 by 20 millimeters (mm) or as large as 200 by 200 mm," the report adds. "Its operating voltage is between 3 and 4.25 volts. Depending on the size, battery capacity varies from 10 milliampere-hours to 5 ampere-hours, with close to 90 percent of this capacity remaining after 1,000 charge-discharge cycles. Each charge typically takes an hour. J. Flex's battery life depends on how it's used, Shin says -- a single charge can last for a month in a sensor, but wouldn't last that long if the battery was powering a display."

PolygamousRanchKid shares a report from The Verge: We've already seen Samsung's new rugged smartphone with a removable battery, the Galaxy XCover Pro, because the company revealed it on its Finnish website before taking it down. Today, though, the company is officially announcing the phone and that it's coming to the U.S. for $499. For that price, you're getting a phone with a swappable battery that's a meaty 4,050mAh, and the phone even supports 15W fast charging, as well as with special docks that use pogo pins. The XCover Pro is intended to be used by workers in industrial settings or out in the field, so that huge battery should theoretically let workers use their phones for longer and give them the option to swap in a fresh battery in a pinch.

Otherwise, the phone's specs are mid-range: a 6.3-inch 2220 x 1080 display (which Samsung says you can use when you have gloves on), a 2GHz octa-core Exynos 9611 processor, 4GB of RAM, and 64GB of internal storage (with support for microSD storage up to 512GB). For cameras, the phone has a 13-megapixel front-facing camera in a corner of the screen and two rear cameras: a 25-megapixel camera and an 8-megapixel camera. It'll also ship with the latest Android 10 and Samsung's One UI 2.0, contrary to information from the early reveal that indicated that the XCover Pro was running Android 9 Pie.

Ever-faster processors led to bloated software, but physical limits may force a return to the concise code of the past. John Naughton: Moore's law is just a statement of an empirical correlation observed over a particular period in history and we are reaching the limits of its application. In 2010, Moore himself predicted that the laws of physics would call a halt to the exponential increases. "In terms of size of transistor," he said, "you can see that we're approaching the size of atoms, which is a fundamental barrier, but it'll be two or three generations before we get that far -- but that's as far out as we've ever been able to see. We have another 10 to 20 years before we reach a fundamental limit." We've now reached 2020 and so the certainty that we will always have sufficiently powerful computing hardware for our expanding needs is beginning to look complacent. Since this has been obvious for decades to those in the business, there's been lots of research into ingenious ways of packing more computing power into machines, for example using multi-core architectures in which a CPU has two or more separate processing units called "cores" -- in the hope of postponing the awful day when the silicon chip finally runs out of road. (The new Apple Mac Pro, for example, is powered by a 28-core Intel Xeon processor.) And of course there is also a good deal of frenzied research into quantum computing, which could, in principle, be an epochal development.

But computing involves a combination of hardware and software and one of the predictable consequences of Moore's law is that it made programmers lazier. Writing software is a craft and some people are better at it than others. They write code that is more elegant and, more importantly, leaner, so that it executes faster. In the early days, when the hardware was relatively primitive, craftsmanship really mattered. When Bill Gates was a lad, for example, he wrote a Basic interpreter for one of the earliest microcomputers, the TRS-80. Because the machine had only a tiny read-only memory, Gates had to fit it into just 16 kilobytes. He wrote it in assembly language to increase efficiency and save space; there's a legend that for years afterwards he could recite the entire program by heart. There are thousands of stories like this from the early days of computing. But as Moore's law took hold, the need to write lean, parsimonious code gradually disappeared and incentives changed.

Insecure storage systems being used by hundreds of hospitals, medical offices and imaging centers are exposing over 1 billion medical images of patients across the world. "Yet despite warnings from security researchers who have spent weeks alerting hospitals and doctors' offices to the problem, many have ignored their warnings and continue to expose their patients' private health information," writes Zack Whittaker from TechCrunch. From the report: "It seems to get worse every day," said Dirk Schrader, who led the research at Germany-based security firm Greenbone Networks, which has been monitoring the number of exposed servers for the past year. The problem is well-documented. Greenbone found 24 million patient exams storing more than 720 million medical images in September, which first unearthed the scale of the problem as reported by ProPublica. Two months later, the number of exposed servers had increased by more than half, to 35 million patient exams, exposing 1.19 billion scans and representing a considerable violation of patient privacy.

A decades-old file format and industry standard known as DICOM was designed to make it easier for medical practitioners to store medical images in a single file and share them with other medical practices. DICOM images can be viewed using any of the free-to-use apps, as would any radiologist. DICOM images are typically stored in a picture archiving and communications system, known as a PACS server, allowing for easy storage and sharing. But many doctors' offices disregard security best practices and connect their PACS server directly to the internet without a password. These unprotected servers not only expose medical imaging but also patient personal health information. Many patient scans include cover sheets baked into the DICOM file, including the patient's name, date of birth and sensitive information about their diagnoses. In some cases, hospitals use a patient's Social Security number to identify patients in these systems.

Samsung's "Galaxy XCover Pro" rugged smartphone includes a feature that all but disappeared from the market: a removable battery. "There are a handful of very low-end smartphones that still have removable batteries, but as a mid-ranger, this would be the highest-end removable-battery phone on the market," reports Ars Technica. From the report: It's hard to say if the XCover Pro is currently official or not. Samsung's Nordic division posted a CES press release that detailed the never-before-seen XCover Pro, complete with specs and pictures, alongside several other previously announced phones. A later update scrubbed all mention of the XCover from the press release. The release said the phone would be for sale in Finland on January 31 for $554, but since the release was pulled, it's unclear if that is still accurate.

Samsung Nordic listed the phone with a Samsung Exynos 9611 SoC, an eight-core, 10nm chip with four Cortex A73 cores and four Cortex A53 cores. This would make it a mid-range phone on par with the "Galaxy A" series. The phone has 4GB of RAM, 64GB of storage that's expandable thanks to a microSD slot, and that sweet 4050mAh removable battery. The display design is... interesting. The display is a 6.3-inch 2400x1000 LCD, which is strange, as most Samsung phones use the company's OLED panels. Like most modern Samsung phones, this device also has a circular cutout in the display for the camera, and while this makes sense on devices with slim top bezels, the XCover's top bezel seems like it would have had plenty of room for a camera. As far as the "rugged" features go, the device features an IP69 water- and dust-resistance rating. There's also a push-to-talk button, side-mounted fingerprint sensor, two rear cameras (25MP + 8MP sensors), and a 13MP front sensor. Strangely, it appears to be running Android 9 Pie instead of the newer Android 10 OS.

Walmart is testing back-of-store automated systems that can collect 800 products an hour, 10 times as many as a store worker. From a report: In the backroom of a Walmart store in Salem, N.H., is a floor-to-ceiling robotic system that the country's largest retailer hopes will help it sell more groceries online. Workers stand on platforms in front of screens assembling online orders of milk, cereal and toilet paper from the hulking automated system. Wheeled robots carrying small baskets move along metal tracks to collect those items. They are bagged for pickup later by shoppers or delivery to homes. Walmart is one of several grocers including Albertsons and Kroger that are using automation to improve efficiency in a fast-growing but costly business that comes with a range of logistical challenges.

The backroom robots could help Walmart cut labor costs and fill orders faster and more accurately. It also could address another problem: unclogging aisles that these days can get crowded with clerks picking products for online orders. A store worker can collect around 80 products from store shelves an hour, estimated John Lert, founder and chief executive of Alert Innovation, the startup that has worked with Walmart to design the system dubbed Alphabot. It is designed to collect 800 products an hour per workstation, operated by a single individual, Mr. Lert said. Workers stock the 24-foot-high machine each day with the products most often ordered online, including refrigerated and frozen foods. Fresh produce is still picked by hand in store aisles.

An anonymous reader quotes a report from CNBC: SoftBank-backed Zume is laying off 360 employees, accounting for about 50 percent of its workforce, and shuttering its robotic pizza business to focus on food packaging. SoftBank invested $375 million in Zume in 2018, giving the start-up a $1 billion valuation. Previously, Zume was valued at just $218 million and had risen $71 million in total, according to Pitchbook. Like other SoftBank-backed startups, Zume used the capital to quickly scale and increase its workforce. But, over the last year, investors have shifted their focus from "growth at all costs" to a clearer path to profitability.

Zume CEO and founder Alex Garden tells CNBC that it's a difficult day for the startup, but the changes being made will focus the business on "the inventions that are showing strong commercial traction." Garden says the company is creating 100 open roles in the Source Packaging unit that employees can reapply for. Pizza Hut has been testing Zume's round boxes on a limited basis. Zume's packaging -- which the company says is covered by a number of patents -- is made of sustainably harvested plant fiber and is industrially compostable. The robot pizza company, which launched in 2015, consisted of an army of robot sauce-spreaders and trucks packed full of ovens. Garden's goal at the time was to become the "Amazon of food."

Intel announced Thunderbolt 4 this week at CES, saying it will arrive in PCs later this year with Intel's new Tiger Lake processor. But, as CNET reports, "the all-purpose port won't be any faster at transferring data than the 4-year-old Thunderbolt 3." From the report: The chipmaker promised it would be four times faster than today's USB, then clarified it was talking about the USB 3.1 version at 10 gigabits per second. Thunderbolt 3, though, already can transfer data at 40Gbps. Still, you can expect other changes. "It standardizes PC platform requirements and adds the latest Thunderbolt innovations," Intel spokeswoman Sarah Kane said in a statement, adding that Intel plans to share more about Thunderbolt 4 later.

Thunderbolt, embraced first by Apple in 2011 and later by some Windows PC makers, has proved popular in high-end computing situations demanding a multipurpose connector. A single Thunderbolt port can link to external monitors, network adapters, storage systems and more. But Intel's years-long ambition to make Thunderbolt mainstream hasn't succeeded. Instead, USB remains the workhorse port.

An anonymous reader shares an excerpt from a CleanTechnica report: Over the last couple of days, as Tesla continues on this monstrous run, the media seems to have been noting that Tesla is now more valuable than any U.S. automaker's market cap ever. (Tesla is currently almost exactly the market cap of Ford and GM combined, around $88 billion.) Even though I would now plant myself firmly in the "bull" camp, this is completely untrue, and I think it paints a problematic picture of Tesla. Let's get right to it -- Tesla is not the most valuable U.S. automaker ever because Tesla's market cap does not have just Tesla automobiles in it.

Currently, especially to outsiders, Tesla's automobiles are the most visible aspect of its business. The problem is Tesla's business is so much more diverse and will affect so many other major industries in the future that calling Tesla an automaker is akin to saying that Google is the most valuable phone company. Sure, Google makes phones, but taking just that aspect of its business into account while ignoring the rest and then claiming it's the most valuable phone company is a mistake at best, and deceitful at worst. I sort of get it. GM doesn't produce HDTVs and Ford doesn't have a wing that runs theme parks or something, so a lot of "analysts" think of Tesla in a similar, narrow-minded way and think Tesla should only be valued based on its automobile business. Tesla's valuation includes its energy (solar and battery) division, autonomy business, and Supercharger network, which is "currently the only capable, nationwide electric vehicle 'refueling' standard," the report says. After you deduct the valuations of those divisions, Tesla becomes "a $30 billion automaker," which makes it "currently the smallest U.S.-based automaker."

In conclusion, CleanTechnica's Frugal Moogal writes: "My point is simply this -- if you're out there parading around the fact that Tesla is the most valuable U.S. automaker ever, you're missing the bigger point. The market is starting to value the rest of Tesla's business, and what I think we're seeing is the beginning of the largest vertically integrated energy and transportation company."

An anonymous reader shares a blog post from Kevin Rooke, investment specialist and co-founder of blockchain marketing agency agency0x: Imagine a startup with $12 billion of revenue, 125%+ YoY revenue growth (two years in a row), and Apple-esque gross margins (30-50%). Without knowing anything else about the business, what would you value it at? $50 billion? $100 billion? More? That's Apple's AirPods business, the fastest-growing segment of the world's most valuable company. Though Apple doesn't share sales numbers for AirPods, industry analysts have converged on estimated sales numbers for each of the last 3 years. In 2017, Apple sold an estimated 15 million devices, each priced at $150. That gave Apple a $2.25 billion revenue boost, only a 1% boost to Apple's $215 billion iPhone revenue.

But in 2018, AirPods sales began to quiet Apple bears. 35 million pairs were sold, still priced at $150. That gave Apple an additional $5.25 billion in revenue, then representing 2.4% of iPhone revenue. And in 2019, Apple has pulled off yet another incredible year of AirPods sales. Apple sold an estimated 60 million units, but in 2019 the prices increased too. Apple's second generation AirPods launched at $200, and their newest variation, the AirPods Pro sell for $250. Assuming an even split of sales between Gen 1, Gen 2, and AirPods Pro, Airpods revenue was $12 billion in 2019. That's 4.5% of Apple's iPhone revenue. Investors are paying attention now. AirPods make as much money as Spotify, Twitter, Snap, and Shopify combined. And considering their triple-digit growth two years in a row, I would be shocked if AirPods didn't earn more money than Uber in 2020.

MojoKid writes: Yesterday, AMD launched its new Ryzen 4000 Series mobile processors for laptops at CES 2020, along with a monstrous 64-core/128-thread third-generation Ryzen Threadripper workstation desktop CPU. In addition to the new processors, on the graphics front the oft-leaked Radeon RX 5600 XT that target's 1080p gamers in the sweet spot of the GPU market was also made official. In CPU news, AMD claims Ryzen 4000 series mobile processors offer 20% lower SOC power, 2X perf-per-watt, 5X faster power state switching, and significantly improved iGPU performance versus its previous-gen mobile Ryzen 3000 products. AMD's U-Series flagship, the Ryzen 7 4800U, is an 8-core/16-thread processor with a max turbo frequency of 4.2GHz and integrated Vega-derived 8-core GPU.

Along with architectural enhancements and the frequency benefits of producing the chips at 7nm, AMD is underscoring up to 59% improved performance per graphics core as well. AMD is also claiming superior single-thread CPU performance versus current Intel-processors and significantly better multi-threaded performance. The initial Ryzen 4000 U-Series line-up consists of five processors, starting with the 4-core/4-thread Ryzen 5 4300U, and topping off with the aforementioned Ryzen 7 4800U. On the other end of the spectrum, AMD revealed some new information regarding its 64-core/128-thread Ryzen Threadripper 3990X processor. The beast chip will have a base clock of 2.9GHz and a boost clock of 4.3GHz with a whopping 288MB of cache. The chip will drop into existing TRX40 motherboards and be available on February 7th for $3990. AMD showcased the chip versus a dual socket Intel Xeon Platinum in the VRAY 3D rendering benchmark beating the Xeon system by almost 30 minutes in a 90-minute workload, though the Intel system retails for around $20K.

Mahdokht Shaibani at Monash University in Melbourne, Australia, and her colleagues have developed a battery with a capacity five times higher than that of lithium-ion batteries. From a report: The battery maintains an efficiency of 99 per cent for more than 200 cycles, and a smartphone-sized version would be able to keep a phone charged for five days. To date, the problem with lithium-sulphur batteries has been that the capacity of the sulphur electrode is so large that it breaks apart over cycles of charging and discharging, and the energy advantage rapidly disappears, says Shaibani. "The electrode will fall apart, and then the battery dies fast." That happens because the sulphur electrode expands and contracts as it cycles, with a volume change of about 78 per cent. Volume change also occurs in electrodes in the lithium-ion batteries that power electric cars and smartphones, but is about eight times smaller. To prevent the electrode disintegrating in their lithium-sulphur battery, the researchers gave the sulphur particles more space to expand and contract. Usually, lithium-sulphur batteries have materials added that bind the particles together inside so the battery doesn't crack as it expands. Shaibani and her team used a smaller amount of a polymer binding material in their electrode, and created more spaced-out structures between the sulphur particles.

An anonymous reader shares a report: The Samsung Galaxy Chromebook is one of the nicest pieces of laptop hardware I've touched in a very long time. Not since Google's 2017 Pixelbook has there been a ChromeOS device this good looking, this powerful, or -- here's the rub -- this expensive. Available sometime in the first quarter, the Galaxy Chromebook starts at $999 and could go much higher if you fully upgrade its RAM and storage. The central conceit of this laptop is that there really is demand for a high-end Chromebook, and while that may be more true in 2020 than it was in 2017, it's not a sure thing. Chrome OS still has a nagging inability to do some of the things you'd want a device that costs more than a thousand dollars to do: run full desktop apps, easily edit photos and video, or play more premium games.

Despite those limitations, Google and Samsung are looking for ways to get Chromebooks to escape the classroom and start appearing in boardrooms. The Galaxy Chromebook could be part of a revitalized effort to do just that. Running down the specs of the Galaxy Chromebook is like hitting a laundry list of the things you might want in a top-tier Windows ultrabook. It has a 13.3-inch 4K AMOLED display and an Intel 10th-gen Core-i5 Processor. There's a fingerprint sensor for unlocking, two USB-C ports, and expandable storage via microSD. The screen rotates 360-degrees and there's an included S-Pen stylus that can be stored in a silo on the device itself. It's built out of aluminum instead of plastic, has a large trackpad, and is less than 10mm thick.

The Verge has been investigating Samsung's "artificial human" project Neon, which seems to be about creating realistic human avatars: A tweet from the project's lead and some leaked videos pretty much confirm this -- although they don't give us nearly enough information to judge how impressive Neon is. The lead of Neon, computer-human interaction researcher Paranav Mistry, tweeted this image, apparently showing one of the project's avatars. Mistry says the company's "Core R3" technology can now "autonomously create new expressions, new movements, new dialog (even in Hindi), completely different from the original captured data...."

In a recent interview, Mistry made clear he thinks "digital humans" will be a major technology in the 2020s... "While films may disrupt our sense of reality, 'virtual humans' or 'digital humans' will be reality. A digital human could extend its role to become a part of our everyday lives: a virtual news anchor, virtual receptionist, or even an AI-generated film star."
Reddit users also found the URLs for videos in the source code on Neon's home page -- and though the videos have since been removed, some of the footage has been archived and analyzed on YouTube.

An anonymous reader quotes Ars Technica: The next big thing in 3D printing just might be so-called "4D materials" which employ the same manufacturing techniques, but are designed to deform over time in response to changes in the environment, like humidity and temperature. They're also sometimes known as active origami or shape-morphing systems. MIT scientists successfully created flat structures that can transform into much more complicated structures than had previously been achieved, including a human face. They published their results last fall in the Proceedings of the National Academy of Sciences...

MIT mechanical engineer Wim van Rees, a co-author of the PNAS paper, devised a theoretical method to turn a thin flat sheet into more complex shapes, like spheres, domes, or a human face. "My goal was to start with a complex 3-D shape that we want to achieve, like a human face, and then ask, 'How do we program a material so it gets there?'" he said. "That's a problem of inverse design..." van Rees and his colleagues decided to use a mesh-like lattice structure instead of the continuous sheet modeled in the initial simulations. They made the lattice out of a rubbery material that expands when the temperature increases. The gaps in the lattice make it easier for the material to adapt to especially large changes in its surface area. The MIT team used an image of [19th century mathematician Carl Friedrich] Gauss to create a virtual map of how much the flat surface would have to bend to reconfigure into a face. Then they devised an algorithm to translate that into the right pattern of ribs in the lattice.

They designed the ribs to grow at different rates across the mesh sheet, each one able to bend sufficiently to take on the shape of a nose or an eye socket. The printed lattice was cured in a hot oven, and then cooled to room temperature in a saltwater bath.

And voila! It morphed into a human face.
"The team also made a lattice containing conductive liquid metal that transformed into an active antenna, with a resonance frequency that changes as it deforms."

"The gigabytes of data we're using -- although invisible -- come at a significant cost to the environment," argues the CBC's senior technology reporter. "Some experts say it rivals that of the airline industry." And as more smart devices rely on data to operate (think internet-connected refrigerators or self-driving cars), their electricity demands are set to skyrocket. "We are using an immense amount of energy to drive this data revolution," said Jane Kearns, an environment and technology expert at MaRS Discovery District, an innovation hub in Toronto. "It has real implications for our climate." [Kearns is also the co-founder of the CanadaCleantech Alliance....]

It's not the gadgets themselves that are drawing so much power, it's the far-flung servers that act as their electronic brains... The data centres, often bigger than a football field, house endless stacks of servers handling many terabytes (thousands of gigabytes) of digital traffic. Just as laptops tend to warm during heavy usage, servers must be cooled to avoid overheating. And cooling so many machines requires plenty of power. Anders Andrae, a researcher at Huawei Technologies Sweden whose estimates are often cited, told CBC News in an email he expects the world's data centres alone will devour up to 651 terawatt-hours of electricity in the next year. That's nearly as much electricity as Canada's entire energy sector produces. And it's just the beginning.

Andrae's calculations, published in the International Journal of Green Technology, suggest data centres could more than double their power demands over the next decade. He projects computing will gobble up 11 per cent of global energy by 2030 and cloud-based services will represent a sizeable proportion of that. "This will become completely unsustainable by 2040," Andrae wrote...

The information and communications technology sector as a whole is thought to be responsible for two to three per cent of global greenhouse gas emissions -- roughly on par with the often-criticized airline sector.
The article also notes that by 2018 Amazon had already switched to renewable energy for at least 50% of its cloud computing servers. And it also adds that tech companies "in Canada and abroad...are coming up with innovative solutions to curb the growing problem."

Solutions being investigated include recovering the low-level heat generated by servers and increasing the speed and capacity of data transfers (including one approach involving a quantum dot multi-wavelength laser).

An anonymous reader quotes Forbes: If you've been following the steady march of progress from Dell's Linux-first Project Sputnik team, you're no doubt aware that the "Developer Edition" variant of the XPS 13 is one of the finest Linux-ready ultrabooks you can buy. Just ahead of CES 2020, Dell is pushing out a few more improvements including a feature that's been hotly requested: fingerprint-reader support. It's one of several enhancements Dell is promising to Linux users for its 10th-generation XPS 13, including a new maximum of 32GB RAM and a redesigned "InfinityEdge" display that adds even more screen real estate, resulting in an adjusted 16:10 aspect ratio to match... Details on fingerprint-reader support are still a bit vague, but Dell says it will be released shortly after the system's February 2020 launch as an OTA (over-the-air) update, and then as part of the preloaded Ubuntu Developer Edition image it ships with the system.
Dell's lead on Project Sputnik developer systems, Barton George, also blogged about Dell's new 86-inch 4K interactive touch monitor, as well as their upcoming Latitude 9510 notebook and 2-in-1 laptops, promising "a new ultra-premium class of products" offering 5G mobile broadband capabilities, AI-based productivity capabilities, and 30-plus hours of battery life.

The blog post ends by noting that "While project Sputnik is the most visible Linux-based offerings from Dell, it is only a small fraction of the over 150 systems that make up Dell's Linux portfolio."
