You probably keep a backup of important personal files, photos, and videos on a flash drive or external hard drive. In the not-too-distant future, you might store that data in DNA instead. French company Biomemory wants to bring personal DNA-based data storage to the public. From a report: Today, the company announced the availability of wallet-sized cards that store one kilobyte of text data each -- the equivalent of a short email -- using DNA as the storage medium. At $1,000 for two identical cards, the price isn't exactly comparable to a memory stick. At least not yet. Erfane Arwani, CEO of Biomemory, sees his firm's offering as an experiment of sorts. "We wanted to demonstrate that our process is ready to be shown to the world," he says.

[...] One major benefit of DNA is that it is a far denser storage medium than current electronics. The Wyss Institute at Harvard estimates that a single gram of DNA can hold around 36 million copies of the Avengers: Endgame movie. It's also stable over time and requires less energy than the solid state drives and hard disk drives used in today's data centers. Once information is encoded into DNA, it doesn't require energy use until it's retrieved using a DNA sequencer. Biomemory is promising a minimum lifespan of 150 years -- a lot longer than current digital data storage methods. Hard disk drives last about five years, while flash drives last for around 10 years.

Slashdot reader XXongo writes: Nuclear power plants have historically been built at gigawatt scale. Recently, however, there has been a new dawn seeing multiple projects to build Small Modular Reactors ("SMRs"), both funded by billionaires and by the U.S. Department of Energy.

Recently one of the players farthest ahead in the development, NuScale Power, canceled their headline project, but many other projects continue. In a lengthy analysis, Michael Barnard thinks that's crazy, and attributes the drive toward small reactors to "a tangled web that includes Bill Gates, Silicon Valley, desperate coal towns, desperate nuclear towns, the inability of the USA to build big infrastructure, the U.S. Department of Energy's budget, magical thinking and more." Due to thermal inefficiencies, small reactors are more expensive per unit of power generated, he points out, and the SMR projects ignore most of the field's history's lessons about both the scale of reactors for commercial success and the conditions needed for success.

They are relying on Wright's Law, that each doubling of the number of manufactured items in production manufacturing would bring cost per item down by 20% to 27%, but Barnard points out that the number of reactors needed to achieve enough economy of scale in production to make the reactors make economic sense is unrealistically optimistic. He concludes that only government programs can meet the conditions for successful deployment of nuclear power.
At one point Barnard characters SMRs as "a bunch of lab technologies that have been around for decades that depend on uranium from Russia, that don't have the physical characteristics for cheap nuclear generation and don't have the conditions for success for nuclear generation will be the saviours of the nuclear industry and a key wedge in fighting climate change...

"I like nuclear generation. I know it's safe enough. I'm not concerned about radiation... I just know that it doesn't have the conditions for success to be built and scaled economically in the 21st Century, and wind, water, solar, transmission and storage do."

The Atlantic writes: Failing a CAPTCHA isn't just annoying — it keeps people from navigating the internet. Older people can take considerably more time to solve different kinds of CAPTCHAs, according to the UC Irvine researchers, and other research has found that the same is true for non-native English speakers. The annoyance can lead a significant chunk of users to just give up.
But is it all also just a big waste of time? The article notes there's now even CAPTCHA-solving services you can hire. ("2Captcha will solve a thousand CAPTCHAs for a dollar, using human workers paid as low as 50 cents an hour. Newer companies, such as Capsolver, claim to instead be using AI and charge roughly the same price.")

And they also write that this summer saw more discouraging news: In a recent study from researchers at UC Irvine and Microsoft:

- most of the 1,400 human participants took 15 to 26 seconds to solve a CAPTCHA with a grid of images, with 81% accuracy.

- A bot tested in March 2020, meanwhile, was shown to solve similar puzzles in an average of 19.9 seconds, with 83% accuracy.
The article ultimately argues that for roughly 20 years, "CAPTCHAs have been engaged in an arms race against the machines," and that now "The burden is on CAPTCHAs to keep up" — which they're doing by evolving. The most popular type, Google's reCAPTCHA v3, should mostly be okay. It typically ascertains your humanity by monitoring your activity on websites before you even click the checkbox, comparing it with models of "organic human interaction," Jess Leroy, a senior director of product management at Google Cloud, the division that includes reCAPTCHA, told me.
But the automotive site Motor Biscuit speculates something else could also be happening. "Have you noticed it likes to ask about cars, buses, crosswalks, and other vehicle-related images lately?" Google has not confirmed that it uses the reCAPTCHA system for autonomous vehicles, but here are a few reasons why I think that could be the case. Self-driving cars from Waymo and other brands are improving every day, but the process requires a lot of critical technology and data to improve continuously.

According to an old Google Security Blog, using reCAPTCHA and Street View to make locations on Maps more accurate was happening way back in 2014... [I]t would ask users to find the street numbers found on Google Street View and confirm the numbers matched. Previously, it would use distorted text or letters. Using this data, Google could correlate the numbers with addresses and help pinpoint the location on Google Maps...

Medium reports that more than 60 million CAPTCHAs are being solved every day, which saves around 160,000 human hours of work. If these were helping locate addresses, why not also help identify other objects? Help differentiate a bus from a car and even choose a crosswalk over a light pole.

Back in 2021 Hurricane Ida knocked out power lines in New Orleans, leaving parts of the city in darkness for 10 days.

So a coalition of community-based organizations (including some churches) decided to build "solar-powered disaster response hubs that could transform the city's approach to resilience," reports the Guardian. So far there's seven, but the group "has ambitions to build dozens more." On a bright, balmy autumn morning a couple of weeks ago [61-year-old pastor Antoine] Barriere climbed a long, steep ladder to show me the 460 solar panels that now cover a third or so of his church's flat roof. The solar panels were generating more than enough energy to power Household of Faith, a non-denominational megachurch with 4,000 mostly Black parishioners in New Orleans East. Downstairs, a cabinet was stacked with backup batteries that were fully charged in case of a power outage — a frequent occurrence thanks to the low-lying city's vulnerability to hurricanes, thunderstorms, high winds, extreme heat and flooding. In a worst-case scenario — no sun, thundery dark skies and power outage — the backup batteries could power essential appliances for a couple of days including the water heater, five commercial fridge freezers storing perishables for the weekly food pantry, and air conditioning for the vast main hall which could be converted into a dormitory-style shelter.

But on this brilliant cloudless morning, most of the solar-generated energy was going into the city's electric grid. New Orleans' one-for-one net metering scheme allows the church to offset its excess clean energy against the utility's dirty energy, and this should become a net zero facility within 12 months... The idea is that each community lighthouse should be an institution locals already know and trust — such as a place of worship, health clinic or community centre — that can be converted into a resilience hub where people can converge during a power outage to get cool, recharge phones, have a meal, connect to a medical device or store medication that requires refrigeration such as insulin. In addition, community lighthouses will be able to keep the services running that people rely on such as the food pantry and religious sermons, while also adding capacity to the city's wider emergency-response efforts as a distribution hub, shelter and possibly even house a makeshift clinic.

Long-time Slashdot reader BishopBerkeley writes: Varjo follows a completely different model from Apple and Meta for its new AR headset. Computing is done on a connected (via a cable) computer. The tradeoff is that the headset can use the extra computing power of the host computer to drive ultrahigh resolution displays that are far more pixel dense than Apple's Vision Pro.

The net result is that the headset is truly useful for demanding applications like professional flight simulators, where $10,000 for a headset is a sensible investment. Furthermore, the headset has a longer life span because its PC resident hardware and software are upgradeable.
From IEEE Spectrum: The Meta Quest 3 is a capable, accessible mixed-reality device. But if you're a mad scientist working on a secret project in an underground lab, it's not going to cut it. Finnish headset manufacturer Varjo has a solution: the XR-4, a new generation of flagship mixed-reality headsets built for unusually demanding users. Varjo, based in Helsinki, serves up displays with record-setting pixel counts, auto-focusing cameras, and a "Secure Edition" that looks like it was ripped straight from a Bond film. The goal? A photo-real mixed-reality experience that lets designers, researchers, and creatives build and work with objects that don't yet physically exist.

"How do you design a car without a clay prototype? How do you sell a yacht you haven't built yet? How do you train a pilot to fly a plane that's still on the ground?" says Patrick Wyatt, Varjo's chief product officer. "Jobs you do right now with physical things, we're virtualizing those."

Varjo's XR-4 headset comes in three different editions, each with escalating features (and price tags). The "entry-level" XR-4, which starts at €3,990 (about US $4,300), homes in on product design and data visualization work that requires crisp virtual reality alongside occasional use of mixed reality. Varjo achieves this with dual 4K displays that leapfrog even the resolution of Apple's upcoming Vision Pro headset... Simulators might benefit from the XR-4's more expensive sibling: the XR-4 Focal Edition. Priced at €9,990 (about $11,000), it justifies its cost with dual gaze-directed autofocus cameras... The Secure Edition is available with fixed-focused or autofocus cameras and priced at €7,990 and €13,990 ($8,700 and $15,200), respectively.

"As of this year, all new Mac computers are powered by Apple's own silicon, ending the company's 15-plus years of reliance on Intel," according to a new report from CNBC.

"Apple's silicon team has grown to thousands of engineers working across labs all over the world, including in Israel, Germany, Austria, the U.K. and Japan. Within the U.S., the company has facilities in Silicon Valley, San Diego and Austin, Texas..." The latest A17 Pro announced in the iPhone 15 Pro and Pro Max in September enables major leaps in features like computational photography and advanced rendering for gaming. "It was actually the biggest redesign in GPU architecture and Apple silicon history," said Kaiann Drance, who leads marketing for the iPhone. "We have hardware accelerated ray tracing for the first time. And we have mesh shading acceleration, which allows game developers to create some really stunning visual effects." That's led to the development of iPhone-native versions from Ubisoft's Assassin's Creed Mirage, The Division Resurgence and Capcom's Resident Evil 4.

Apple says the A17 Pro is the first 3-nanometer chip to ship at high volume. "The reason we use 3-nanometer is it gives us the ability to pack more transistors in a given dimension. That is important for the product and much better power efficiency," said the head of Apple silicon, Johny Srouji . "Even though we're not a chip company, we are leading the industry for a reason." Apple's leap to 3-nanometer continued with the M3 chips for Mac computers, announced in October. Apple says the M3 enables features like 22-hour battery life and, similar to the A17 Pro, boosted graphics performance...

In a major shift for the semiconductor industry, Apple turned away from using Intel's PC processors in 2020, switching to its own M1 chip inside the MacBook Air and other Macs. "It was almost like the laws of physics had changed," Ternus said. "All of a sudden we could build a MacBook Air that's incredibly thin and light, has no fan, 18 hours of battery life, and outperformed the MacBook Pro that we had just been shipping." He said the newest MacBook Pro with Apple's most advanced chip, the M3 Max, "is 11 times faster than the fastest Intel MacBook Pro we were making. And we were shipping that just two years ago." Intel processors are based on x86 architecture, the traditional choice for PC makers, with a lot of software developed for it. Apple bases its processors on rival Arm architecture, known for using less power and helping laptop batteries last longer.

Apple's M1 in 2020 was a proving point for Arm-based processors in high-end computers, with other big names like Qualcomm — and reportedly AMD and Nvidia — also developing Arm-based PC processors. In September, Apple extended its deal with Arm through at least 2040.
Since Apple first debuted its homegrown semiconductors in 2010 in the iPhone 4, other companies started pursuing their own custom semiconductor development, including Amazon, Google, Microsoft and Tesla.

CNBC reports that Apple is also reportedly working on its own Wi-Fi and Bluetooth chip. Apple's Srouji wouldn't comment on "future technologies and products" but told CNBC "we care about cellular, and we have teams enabling that."

Consumer Reports awarded a "recommended" rating to Tesla's Modey Y this year, "with owners reporting fewer issues with its suspension, in-car electronics and general build quality than in previous years". Tesla's Model 3 also earned a "recommended" rating.

"Tesla's Model 3 and Model Y are now the sweet spot in the automotive industry when it comes to building electric cars," says Jake Fisher, the senior director of auto testing for Consumer Reports. "While Tesla is still a relatively new car company, it has more experience producing EVs than any other automaker."

But how about the larger universe of all automakers? Electric vehicle owners continue to report far more problems with their vehicles than owners of conventional cars or hybrids, according to Consumer Reports' newly released annual car reliability survey. The survey reveals that, on average, EVs from the past three model years had 79 percent more problems than conventional cars...

"Most electric cars today are being manufactured by either legacy automakers that are new to EV technology, or by companies like Rivian that are new to making cars," says Jake Fisher, senior director of auto testing at Consumer Reports. "It's not surprising that they're having growing pains and need some time to work out the bugs." Fisher says some of the most common problems EV owners report are issues with electric drive motors, charging, and EV batteries...

This year's survey data show that hybrids continue to be among the most reliable vehicle type: Hybrids have 26 percent fewer problems than conventional models, even though they have both a conventional powertrain and an electric motor and therefore more potential problem spots than conventional cars. "It might not seem that long ago, but Toyota launched the Prius hybrid about 25 years ago," Elek says. "Automakers have been making hybrids long enough that they've gotten really good at it. Plus, many hybrids are also made by manufacturers that tend to produce reliable vehicles overall, such as Toyota, Hyundai, and Kia." Hybrids also are not typically loaded with high-tech features like multiple customizable displays that can be problem-prone, which is why Fisher says they are great options for drivers who are more interested in getting ideal fuel mileage than they are in bells and whistles. "These vehicles are not necessarily a tour de force of technology, so there's just less that can go wrong with them," he says.

Plug-in hybrid electric vehicles (PHEVs), which have both a battery for short-range electric driving and an internal combustion engine for long-range driving, are the least reliable category — 146 percent more problems than conventional cars. "PHEVs are sort of like an EV and a conventional car rolled into one, so by their nature they have more things that can go wrong with them," Fisher says.
There are exceptions, notes the auto testing director. Toyota's RAV4 Prime plug-in hybrid "is one of the most reliable models in our survey this year. Similarly, the Ford F-150 hybrid has transmission and other issues that buck the trend of strong hybrid reliability."

Tuesday the New York Times reported that while hosting the global climate summit, the United Arab Emirates also hoped to lobby for oil and gas deals around the world.

But Friday the United Arab Emirates announced that they'd also started a $30 billion climate fund, reports Reuters, and that fund "aims to attract $250 billion of investment by the end of the decade."

The New York Times notes the fund started just months ago, and "at least 20 percent of the funds, would be earmarked for projects in the developing world, where it is especially difficult to finance clean energy projects because interest rates are high and lenders shy away from what they perceive as risky investments."

The Washington Post notes that "It immediately becomes one of the world's largest climate-focused investment funds." "This is a big deal," said Mona Dajani, global head of renewables, energy and infrastructure at the law firm Shearman and Sterling. "We have seen other programs previously, but not at this level. They were too scattered, too small, not aligned to the broader financial sector."

The lack of cash feeds into other challenges that can make it impossible to scale up clean energy in some countries. Without a steady pipeline of projects, there are no established supply chains, and nations find themselves locked out of markets for key components that are in high demand elsewhere, such as solar cells and critical minerals used to make giant batteries that store renewable power. The Global South will need an immense amount of such battery storage by the end of the decade, according to the Rockefeller Foundation, enough to store about as much power as is produced by 90 large nuclear plants. The storage is used to bottle wind and solar power and distribute it back into grids after dark and when the wind dies down.
The Post also reports that "the money to fund the projects will come largely from oil revenue." While the UAE framed its initiative as a call to global action, it is at least partly geared toward generating returns. It is one of several forays the UAE is making into clean-energy finance as it seeks to diversify its economy amid predictions the demand for oil will slump in coming years... The new initiative puts a spotlight on the UAE's evolving role in the fight against climate change. The country is at once one of the world's biggest contributors to warming, pumping massive amounts of oil into the global economy, while also using its fossil fuel wealth to put itself on the vanguard of energy innovation.

Tesla's new Cybertruck is more than their first new model since 2020, reports the Verge: Tesla announced a new "Powershare" vehicle-to-load charging capability, only available on the new Cybertruck. The feature will allow Cybertruck owners to power their camping equipment, power tools, or even their entire home during a blackout, just by using their electric truck as a mobile generator.

The truck also features a 240-volt outlet in the rear bed that can be used to charge other EVs. An image on Tesla's website shows the Cybertruck charging a Model Y.

The Cybertruck can put out as much as 11.5kW, which is more than the Ford F-150 Lightning's 9.6kW of onboard power or the GMC Sierra Denali EV's 10.2kW. Tesla has been talking about manufacturing vehicles with bidirectional charging capabilities for several years now, first teasing the feature at its Battery Day event in 2020. Since then, many of its competitors have adopted the feature for their EVs, including Ford, GM, Hyundai, Kia, and others...

In essence, it treats high-capacity lithium-ion batteries not only as tools to power EVs but also as backup storage cells to charge other electric devices, an entire home, or even to send power to the electrical grid for possible energy savings... Customers who want to take advantage of the Powershare feature in their homes will need a Tesla Powerwall (of course) and a Wall Connector for the most seamless connection.
Tesla held a launch event for the vehicle on Thursday, and demand appears to be high. Jalopnik reports Tesla is now offering people who'd reserved a Cybertruck a $1,000 discount if they'll instead order another Tesla model.

The world's biggest operational experimental nuclear fusion center has been inaugurated in Naka, Japan. The Guardian reports: The goal of the JT-60SA reactor is to investigate the feasibility of fusion as a safe, large-scale and carbon-free source of net energy -- with more energy generated than is put into producing it. The six-storey-high machine, in a hangar in Naka, north of Tokyo, comprises a doughnut-shaped "tokamak" vessel set to contain swirling plasma heated up to 200mC (360mF). It is a joint project between the European Union and Japan, and is the forerunner for its big brother in France, the under-construction International Thermonuclear Experimental Reactor (ITER).

Sam Davis, the deputy project leader for the JT-60SA, said the device would "bring us closer to fusion energy." "It's the result of a collaboration between more than 500 scientists and engineers and more than 70 companies throughout Europe and Japan," Davis said at Friday's inauguration. The EU energy commissioner, Kadri Simson, said the JT-60SA was "the most advanced tokamak in the world," and called the start of operations "a milestone for fusion history." "Fusion has the potential to become a key component for energy mix in the second half of this century," Simson added.

Windows users are reporting that Hewlett Packard's HP Smart application is appearing on their systems, despite them not having any of the company's hardware attached. From a report: While Microsoft has remained tight-lipped on what is happening, folks on various social media platforms noted the app's appearance, which seems to afflict both Windows 10 and Windows 11. The Windows Update mechanism is used to deploy third-party applications and drivers as well as Microsoft's updates, and we'd bet someone somewhere has accidentally checked the wrong box.

Up to now, the response from affected users has been one of confusion. One noted on Reddit: "I thought that was just me. I didn't install it, it just appeared on new apps in start menu out of nowhere." Another said: "I just checked and I had it installed too. Checking the event log for the Microsoft Store shows that it installed earlier today, but I definitely did [not] request or initiate it because I do not have any devices from HP." And, of course, there was the inevitable: "Would it be that hard for Microsoft to just provide an operating system without needless bloat?" To be clear, not all users are affected.

Anton Shilov reports via Tom's Hardware: Engineers from Frore Systems have integrated the company's innovative solid-state AirJet cooling system, which provides impressive cooling capabilities despite a lack of moving parts, into an M2-based Apple MacBook Air. With proper cooling, the relatively inexpensive laptop matched the performance of a more expensive MacBook Pro based on the same processor. The lack of a fan is probably one of the main advantages of Apple's MacBook Air over its more performant siblings, but it also puts the laptop at a disadvantage. Fanless cooling doesn't have moving parts (which is a plus), but it also cannot properly cool down Apple's M1 or M2 processor under high loads, which is why a 13-inch MacBook Air powered by M1 or M2 system-on-chip is slower than 13-inch MacBook Pro based on the same SoC. However, making a MacBook Air run as fast as a 13-inch MacBook Pro is now possible. A video posted to YouTube by PC World shows how the AirJet system works. They also released a recent demo showing off the strength of the AirJet technology.

Amazon's cloud-computing unit announced updated versions of its in-house computer chips while also forging closer ties with Nvidia -- dual efforts designed to ensure it can get enough supplies of crucial data-center processors. From a report: New homegrown Graviton4 chips will have as much as 30% better performance than their predecessors, Amazon Web Services said at its annual re:Invent conference in Las Vegas. Computers using the processors will start coming online in the coming months.

The company also unveiled Trainium2, an updated version of a processor designed for artificial intelligence systems. It will begin powering new services starting next year, Amazon said. That chip provides an alternative to so-called AI accelerators sold by Nvidia -- processors that have been vital to the build-out of artificial intelligence services. But Amazon also touted "an expansion of its partnership" with Nvidia, whose chief executive officer, Jensen Huang, joined AWS counterpart Adam Selipsky on stage. AWS will be the first big user of an updated version of that company's Grace Hopper Superchip, and it will be one of the data-center companies hosting Nvidia's DGX Cloud service.

Barriers to entry in an industry dominated by TSMC and Nvidia are very high. From a report: In the drama that has just played out in Silicon Valley over the future of OpenAI, one side plot concerned an ambitious chip venture by its chief executive Sam Altman. Before he was ousted and reinstated to the helm of the company, Altman had sought to raise as much as $100bn from investors in the Middle East and SoftBank founder Masayoshi Son to build a rival to compete with sector giants Nvidia and Taiwan Semiconductor Manufacturing Co. This would be a vast undertaking. And one where $100bn may not go very far. Given that the US chip designer and Taiwanese chipmaker are critical to all things generative AI, Altman is unlikely to be the only one with hopes of taking them on. But the barriers to entry -- moats in Silicon Valley parlance -- are formidable.

Nvidia has about 95 per cent of the markets for GPU, or graphics processing units. These computer processors were originally designed for graphics but have become increasingly important in areas such as machine learning. TSMC has about 90 per cent of the world's advanced chip market. These businesses are lucrative. TSMC runs on gross margins of nearly 60 per cent, Nvidia at 74 per cent. TSMC makes $76bn in sales a year. The impressive figures make it seem as though there is plenty of room for more contenders. A global shortage of Nvidia's AI chips makes the prospect of vertical integration yet more attractive. As the number of GPUs required to develop and train advanced AI models grows rapidly, the key to profitability for AI companies lies in having stable access to GPUs.

[...] It is one thing for companies to design customised chips. But Nvidia's profitability comes not from making chips cost-efficient, but by providing a one-stop solution for a wide range of tasks and industries. For example, Nvidia's HGX H100 systems, which can go for about $300,000 each, are used to accelerate workloads for everything from financial applications to analytics. Coming up with a viable rival for the HGX H100 system, which is made up of 35,000 parts, would take much more than just designing a new chip. Nvidia has been developing GPUs for more than two decades. That head start, which includes hardware and related software libraries, is protected by thousands of patents. Even setting aside the challenges of designing a new AI chip, manufacturing is where the real challenge lies.

Simon Sharwood reports via The Register: Amazon Web Services has announced the WorkSpaces Thin Client -- a device dedicated to connecting to its WorkSpaces desktop-as-a service offering and based on Amazon's own "Fire Cube" smart TV box. The $195 machine has the same hardware as the Fire Cube: the eight-core Arm-powered Amlogic POP1-G SoC, plus 2GB of LPDDR4 RAM, 10/100 ethernet, and a single USB-A 2.0 port. Bluetooth is included to connect other peripherals. A second HDMI output can be added by acquiring an $85 hub that also offers four more USB ports. Like the Fire TV Cube, the Thin Client also runs a modified cut of Android.

But there the similarities end. AWS created custom firmware and ripped out anything remotely related to running a consumer device, replacing it with software designed solely to create a secure connection between the device and desktops running in the Amazonian cloud. Amazon Business -- the B2B version of Jeff Bezos's digital souk -- will ship the device to your door, and charge it to your AWS bill. At least if you are in the USA. Europe will get the Thin Client in early 2024, and it'll eventually migrate elsewhere.

AWS decided to base the box on the Fire Cube because, according to a corporate blog post, AWS customers expressed a desire for cheaper and easier-to-maintain client devices. As AWS execs searched for a well-priced box, they considered the Fire TV Cube, found it fit the bill and noted it was already being made at scale. Keeping things in-house made sense, too. And so we find ourselves with AWS taking on established thin client providers. The cloudy concern is also keen to have a crack at the thick wedge of the enterprise PC market: call centers, payment processing centers, and other environments with lots of users and high staff turnover due to factors like seasonal demand for workers.

Google Drive users are reporting files mysteriously disappearing from the service, with some posters on the company's support forums claiming six or more months of work have unceremoniously vanished. From a report: The issue has been rumbling for a few days, with one user logging into Google Drive and finding things as they were in May 2023. According to the poster, almost everything saved since then has gone, and attempts at recovery failed. Others chimed in with similar experiences, and one claimed that six months of business data had gone AWOL. There is little information regarding what has happened; some users reported that synchronization had simply stopped working, so the cloud storage was out of date.

Others could get some of their information back by fiddling with cached files, although the limited advice on offer for the affected was to leave things well alone until engineers come up with a solution. A message purporting to be from Google support also advised not to make changes to the root/data folder while engineers investigate the issue. Some users speculated that it might be related to accounts being spontaneously dropped. We've asked Google for its thoughts and will update should the search giant respond.

"On a typical day 1,300 planes take off and land at Heathrow Airport, and keeping that going requires around 20 million litres of jet fuel every day," reports the BBC. "That's the equivalent of filling up your car around 400,000 times.

"But, when it comes to fuel, airports around the world are having to have a major rethink..." To be of any use to the aviation industry, hydrogen needs to be in its liquid form, which involves chilling it to minus 253C. Handling a liquid at that kind of temperature is immensely challenging. Given the chance, liquid hydrogen will "boil-off" and escape as a gas — potentially becoming a hazard. So tanks, pipes and hoses all have to be extra-insulated to keep the liquid cold.

France's Air Liquide has a lot of experience in this area. For around 50 years it has been supplying cryogenic hydrogen to the Ariane rockets of the European Space Agency (ESA)... Over the past three years, in partnership with Airbus and France's biggest airport operator, Group ADP, Air Liquide has been investigating the potential of hydrogen in the aviation business. It is also part of the H2Fly consortium which this summer successfully flew an aircraft using liquid hydrogen. For Air Liquide, it was an opportunity to test systems for fuelling a hydrogen aircraft...

However, installing the equipment needed to store and distribute hydrogen at airports will not be cheap. The consultancy Bain & Company estimates it could cost as much as a billion dollars per airport. One start-up, Universal Hydrogen, says it has a solution... The company has developed special tanks to hold liquid hydrogen (UH calls them modules), which can then be trucked to the airport. The modules are designed to slot straight into the aircraft, where they can be plugged into the propulsion system. No need for pipes, hoses and pumps.

The modules are extremely well insulated and can keep the hydrogen in its liquid form for four days. Two modules would hold 360kg of hydrogen and would be able to fly an aircraft 500 miles, plus an extra 45 minutes of flight time in reserve.

America's long-standing Advanced Research Projects Agency (or ARPA) developed the foundational technologies for the internet.

This week its energy division announced $42 million for projects enabling a "more secure and reliable" energy grid, "allowing it to utilize more solar, wind, and other clean energy." But specifically, they funded 15 projects across 11 states to improve the reliability, resiliency, and flexibility of the grid "through the next-generation semiconductor technologies." Streamlining the coordinated operation of electricity supply and demand will improve operational efficiency, prevent unforeseen outages, allow faster recovery, minimize the impacts of natural disasters and climate-change fueled extreme weather events, and redcude grid operating costs and carbon intensity.
Some highlights:

• The Georgia Institute of Technology will develop a novel semiconductor switching device to improve grid control, resilience, and reliability.
• Michigan's Great Lakes Crystal Technologies (will develop a diamond semiconductor transistor to support the control infrastructure needed for an energy grid with more distributed generation sources and more variable loads
• Lawrence Livermore National Laboratory will develop an optically-controlled semiconductor transistor to enable future grid control systems to accommodate higher voltage and current than state-of-the-art devices.
• California's Opcondys will develop a light-controlled grid protection device to suppress destructive, sudden transient surges on the grid caused by lightning or electromagnetic pulses.
• Albuquerque's Sandia National Laboratories will develop novel a solid-state surge arrester protecting the grid from very fast electromagnetic pulses that threaten grid reliability and performance.

America's Secretary of Energy said the new investment "will support project teams across the country as they develop the innovative technologies we need to strengthen our grid security and bring reliable clean electricity to more families and businesses — all while combatting the climate crisis."

"The cornerstone of the open-source philosophy is that the recipients of technology should have access to all its building blocks..." writes the European Organization for Nuclear Research, "in order to study it, modify it and redistribute it to others." This includes mechanical designs, schematics for electronics, and software code. Ever since releasing the World Wide Web software under an open-source model in 1994, CERN has continuously been a pioneer in this field, supporting open-source hardware (with the CERN Open Hardware Licence), open access (with the Sponsoring Consortium for Open Access Publishing in Particle Physics — SCOAP3) and open data (with the Open Data Portal for the LHC experiments).

The CERN Open Data portal is a testimony to CERN's policy of Open Access and Open Data. The portal allows the LHC experiments to share their data with a double focus: for the scientific community, including researchers outside the CERN experimental teams, as well as citizen scientists, and for the purposes of training and education through specially curated resources. The first papers based on data from the CERN Open Data portal have been published. Several CERN technologies are being developed with open access in mind. Invenio is an open-source library management package, now benefiting from international contributions from collaborating institutes, typically used for digital libraries. Indico is another open-source tool developed at CERN for conference and event management and used by more than 200 sites worldwide, including the United Nations. INSPIRE, the High Energy Physics information system, is another example of open source software developed by CERN together with DESY, Fermilab and SLAC.
And on Wednesday the European Organization for Nuclear Research launches its new Open Source Program Office "to help you with all issues relating to the release of your software and hardware designs." Sharing your work with collaborators in research and industry has many advantages, but it may also present some questions and challenges... The OSPO will support you, whether you are a member of the personnel or a user, to find the best solution by giving you access to a set of best practices, tools and recommendations. With representatives from all sectors at CERN, it brings together a broad range of expertise on open source practices... As well as supporting the CERN internal community, the OSPO will engage with external partners to strengthen CERN's role as a promoter of open source.

Open source is a key pillar of open science. By promoting open source practices, the OSPO thus seeks to address one of CERN's core ambitions: sharing our knowledge with the world. Ultimately, the aim is to increase the reach of open source projects from CERN to maximise their benefits for the scientific community, industry and society at large.
For Wednesday's launch event "We will host distinguished open source experts and advocates from Nvidia, the World Health Organization and the Open Source Hardware Association to discuss the impact and future of open source." There will be a live webcast of the event.

There's yet another technological revolution happening, reports the Los Angeles Times. Bowling alleys across America "are ditching traditional pinsetters — the machines that sweep away and reset pins — in favor of contraptions that employ string.

"Think of the pins as marionettes with nylon cords attached to their heads. Those that fall are lifted out of the way, as if by levitation, then lowered back into place after each frame... European bowling alleys have used string pinsetters for decades because they require less energy and maintenance.

"All you need is someone at the front counter to run back when the strings tangle." String pinsetters mean big savings, maybe salvation, for an industry losing customers to video games and other newfangled entertainment. That is why the U.S. Bowling Congress recently certified them for tournaments and league play. But there is delicate science at play here. Radius of gyration, coefficient of restitution and other obscure forces cause tethered pins to fly around differently than their free-fall counterparts. They don't even make the same noise. Faced with growing pushback, the bowling congress published new research this month claiming the disparity isn't nearly as great as people think.
Using a giant mechanical arm, powered by hydraulics and air pressure, they rolled "thousands of test balls from every angle, with various speeds and spins, on string-equipped lanes," according to the article: They found a configuration that resulted in 7.1% fewer strikes and about 10 pins fewer per game as compared to bowling with traditional pinsetters... Officials subsequently enlisted 500 human bowlers for more testing and, this time, reported finding "no statistically significant difference." But hundreds of test participants commented that bowling on strings felt "off." The pins seemed less active, they said. There were occasional spares whereby one pin toppled another without making contact, simply by crossing strings.

Nothing could be done about the muted sound. It's like hearing a drum roll — the ball charging down the lane — with no crashing cymbal at the end.
Still, one Northern California bowling alley spent $1 million to install the technology, and believes it will save them money — partly by cutting their electric bill in half. "We had a full-time mechanic and were spending up to $3,000 a month on parts."

The article also remembers that once upon a time, bowling alleys reset their pins using pinboys, "actual humans — mostly teenagers... scrambling around behind the lanes, gathering and resetting by hand," before they were replaced by machines after World War II.
