Chinese researchers show off a swarm of drones collectively navigating a dense forest they've never encountered. TechCrunch reports: Researchers at Zheijang University in Hangzhou have succeeded, however, with a 10-strong drone swarm smart enough to fly autonomously through a dense, unfamiliar forest, but small and light enough that each one can easily fit in the palm of your hand. It's a big step toward using swarms like this for things like aerial surveying and disaster response.

Based on an off-the-shelf ultra-compact drone design, the team built a trajectory planner for the group that relies entirely on data from the onboard sensors of the swarm, which they process locally and share with each other. The drones can balance or be directed to pursue various goals, such as maintaining a certain distance from obstacles or each other, or minimizing the total flight time between two points, and so on.

The drones can also, worryingly, be given a task like "follow this human." We've all seen enough movies to know this is how it starts ... but of course it could be useful in rescue or combat circumstances as well. A part of their navigation involves mapping the world around them, of course, and the paper includes some very cool-looking 3D representations of the environments the swarm was sent through. Zhou et alThe study is published in the most recent issue of the journal Science Robotics, which you can read here, along with several videos showing off the drones in action.

An anonymous reader quotes a report from MacRumors: Apple has agreed to settle a long-lasting six-year class-action lawsuit that accused it of knowingly slowing down iPhone 4S devices following the iOS 9 update in 2015, agreeing to pay some iPhone 4S owners who had experienced poor performance $15 each for their claims. The class-action lawsuit was initially filed in December 2015 by plaintiffs representing a group of iPhone 4S customers from New York and New Jersey. The lawsuit accused Apple of falsely marketing the iOS 9 update as providing enchanted performance on devices it supports, including the iPhone 4S.

Under the settlement, Apple allocated $20 million to compensate iPhone 4S owners in New York and New Jersey who experienced poor performance after updating to iOS 9. Customers who believe they are entitled to the $15 must "submit a declaration under the penalty of perjury that, to the best of their knowledge, they downloaded iOS 9, or any version thereof, onto their iPhone 4S... their iPhone 4S experienced a significant decline in performance as a result, are entitled to a payment of $15 per applicable device." A website will be created where customers who believe they are entitled to the settlement will be able to submit a form, providing their name, email, iPhone 4S serial number (if possible), and mailing address.

AMD announced the Ryzen 5000 C-series for Chromebooks today. "The top chip in the series has eight of AMD's Zen 3 cores, giving systems that use it more x86 CPU cores than any other Chromebook," reports Ars Technica. From the report: The 7nm Ryzen 5000 C-series ranges from the Ryzen 3 5125C with two Zen 3 cores and a base and boost clock speed of 3 GHz, up to the Ryzen 7 5825C with eight cores and a base clock speed of 2 GHz that can boost to 4.5 GHz. For comparison, Intel's Core i7-1185G7, found in some higher end Chromebooks, has four cores and a base clock speed of 3 GHz that can boost to 4.8 GHz.

On their own, the chips aren't that exciting. They seemingly offer similar performance to the already-released Ryzen 5000 U-series chips. The Ryzen 5000 C-series also uses years-old Vega integrated graphics rather than the upgraded RDNA 2 found in Ryzen 6000 mobile chips, which, upon release, AMD said are "up to 2.1 times faster." But for someone who's constantly pushing their Chromebook to do more than just open a Chrome tab or two, the chips bring potentially elevated performance than what's currently available.

An anonymous reader quotes a report from CNET: Volvo will only sell electrified cars in the US beginning with the 2023 model year, the automaker confirmed Tuesday. "Electrified" means that in addition to EVs, Volvo will continue to offer gas-powered cars, but they'll all either have mild-hybrid or plug-in hybrid technology. Volvo will continue to offer plug-in hybrid powertrains, as well. In fact, these T8 Recharge models recently received a power boost, in addition to increased electric-only driving range. The 2023 model year Volvos should arrive at dealers this summer. Meanwhile, Volkswagen says it has "sold out" of battery-powered models in the U.S. and Europe for this year as persistent supply chain bottlenecks hit global production.

An anonymous reader shares a report: A funny thing happened in 2020: AMD won the gaming laptop for the first time ever. Until the Asus Zephyrus G14, we'd never seen a laptop with an AMD CPU and AMD GPU run circles around the competition. Since then, we've repeatedly seen that "AMD laptop" no longer means cheap. But now, AMD is setting its sights higher than mid-range gaming machines -- it just revealed it's building a new CPU aimed at the "pinnacle of gaming performance" with the "highest core, thread and cache ever." The new CPU line is codenamed "Dragon Range," and they'll live exclusively at 55W TDP and up -- enough power that they'll "largely exist in the space where gaming laptops are plugged in the majority of the time," says AMD director of technical marketing Robert Hallock.

According to the Irish Times, citing new figures from the Central Statistics Office, data centers used up a greater share of electricity consumption than rural homes in the State last year. From the report: The overall share of metered electricity consumed by data centers has almost tripled in just six years, from 5 percent in 2015 to 14 percent last year. By comparison, urban homes accounted for 21 per cent of metered electricity consumed in 2021 compared with 12 percent consumed by rural dwellings. The figure for electricity consumption by data centers last year represents an increase of 32 percent in that year.

Data centers consumed 265 per cent more electricity in the three-month period between October and December 2021 compared with the three months between January and March 2015. Total metered electricity consumption increased by 16 per cent over the six years with data centers accounting for the 70 per cent of the increased consumption over that period. The surge in electricity use by data centers has come under scrutiny due to concerns about the State's energy supply and the targeted reduction in carbon emissions to tackle climate change. "There should be more discussion and more serious consideration of a moratorium [to block the opening of more data centers in order to reduce emissions]," said Dr Patrick Bresnihan, a geography lecturer at Maynooth University.

Allowing electricity consumption by data centers to continue to increase would make it harder for the Government to push policies where it is asking individuals to reduce consumption at a time "when consumption by data centers is so high and clearly just growing," said Dr Bresnihan.

The Biden administration plans to begin a $3.1 billion effort on Monday to spur the domestic production of advanced batteries, which are essential to its plan to speed the adoption of electric vehicles and renewable energy. The New York Times reports: President Biden has prodded automakers to churn out electric vehicles and utilities to switch to solar, wind and other clean energy, saying the transitions are critical to eliminating the pollution that is dangerously heating the planet. In the wake of surging energy prices caused largely by Russia's invasion of Ukraine, administration officials also have described the transition to clean energy as a way to insulate consumers from the fluctuation of global oil markets and achieve true energy independence. Jennifer Granholm, the energy secretary, last week called renewable energy "the greatest peace plan this world will ever know." Yet currently, lithium, cobalt and other minerals needed for electric car batteries and energy storage are processed primarily in Asia. China alone controls nearly 80 percent of the world's processing and refining of those critical minerals.

Ms. Granholm plans to announce the funding plan on Monday during a visit to Detroit, a senior administration official said. The $3.1 billion in grants, along with a separate $60 million program for battery recycling, is an effort to "reduce our reliance on competing nations like China that have an advantage over the global supply chain," according to a Department of Energy statement. The funding is aimed at companies that can create new, retrofitted or expanded processing facilities as well as battery recycling programs, officials with the Department of Energy said. The grants will be funded through the $1 trillion infrastructure law, which includes more than $7 billion to improve the domestic battery supply chain.

Venkat Srinivasan, director of the Argonne Collaborative Center for Energy Storage Science at Argonne National Laboratory, told the panel that the United States "can become a dominant force in energy storage technology" and has a "once-in-a-lifetime opportunity to seize the moment." Between electric vehicles and grid storage, the market for lithium-ion batteries in the United States is expected to increase by a factor of 20 to 30 in the next decade but a secure domestic supply chain is needed, Dr. Srinivasan said. The Biden administration wants half of all new vehicles sold in the United States to be electric by 2030. The president also has issued procurement guidelines to transform the 600,000-vehicle federal fleet, so that all new cars and trucks purchased by the federal government by 2035 are zero-emission.

This week saw the 36th anniversary of the Chernobyl disaster -- which had occurred just days before the Soviet Union's annual May Day celebration in 1986 -- and featured lots of patriotic outdoor parades.

At the time Lev Golinkin was a 6-year-old living less than 300 miles away in the Ukrainian town now called Kharkiv. Writing for CNN, Golinkin remembers that Moscow "had remained silent, refusing to admit anything had occurred until the radioactive cloud from Chernobyl was detected in Scandinavia on April 28, making it impossible to hide the catastrophe any longer." Even then, Golinkin remembers that they "grossly downpayed the issue...." On April 29, three days after the Chernobyl disaster, Moscow issued a terse television announcement informing citizens that a reactor was damaged and aid was being provided to those who required it. The announcement was less than 20 seconds

The days and weeks that followed were filled with a torrent of rumors and innuendo swirling around living rooms across the USSR while Moscow continued to pile over the explosion with secrecy and obfuscation. The Politburo began to loosen up restrictions on freedom of speech, but the confusion remained. No one knew the truth, but everyone knew the Kremlin was lying -- and that was about the only certainty around...

[T]here was no rationalizing away the radiation. Moscow's refusal to cancel May Day festivities exposed the hollow horror of the Soviet Union -- even the most faithful believers in communism realized they lived in a country that thrust millions of people into danger just so it could hold a parade. Soviet Premier Mikhail Gorbachev himself admitted Chernobyl -- which eroded faith in the Soviet system, poisoned vast tracts of land and cost billions to clean up -- contributed to the collapse of the USSR more than any other factor. Decades of Moscow's secrecy around the disaster makes it impossible to arrive at an accurate estimate of casuaties, and to this day, experts continue to guess and reassess the true impact of Chernobyl....

For nearly 70 years, the Soviets in Kremlin had generations of citizens tolerate bloodshed papered over by mendacity and propaganda. The same is happening today, during Moscow's savage war in Ukraine. The media formats may be somewhat different, but the lies continue...

My family and I fled the Soviet Union in 1989. Watching the horrors in Ukraine unfold from America is surreal, in no small part because it feels like the intervening decades between the falls of communism and today have evaporated.

Slashdot reader XXongo brings word of a new three-part documentary — streaming free now — that tries to understand America's early inaction on climate change. Looking back over the last few decades, The Power of Big Oil explores how the fuel industry "successfully set up a campaign to discredit climate science and targetting individual politicians to vote against measures to curb climate change."

The Guardian notes that the series includes an interview with a U.S. senator who they say "blames the oil industry for malignly claiming the science of climate change was not proved when companies such as Exxon and Shell already knew otherwise from their own research."

As far back as 25 years ago, the senator says, "they had evidence in their own institutions that countered what they were saying publicly. I mean — they lied." The documentary's makers have dug out a parade of former oil company scientists, lobbyists and public relations strategists who lay bare how the US's biggest petroleum firm, Exxon, and then the broader petroleum industry, moved from attempting to understand the causes of a global heating to a concerted campaign to hide the making of an environmental catastrophe. Over three episodes — called Denial, Doubt, Delay — the series charts corporate manipulation of science, public opinion and politicians that mirrors conduct by other industries, from big tobacco to the pharmaceutical companies responsible for America's opioid epidemic.

Some of those interviewed shamefacedly admit their part in the decades-long campaign to hide the evidence of climate change, discredit scientists and delay action that threatened big oil's profits.

Others almost boast about how easy it was to dupe the American public and politicians, with consequences not just for the US but every country on the planet.
In one video clip an aide to a climate-conscious senator remembers that "You had reams of material coming out of the government. They were at the National Oceanic and Atmospheric Administration, at NASA — this expanding network of people, working on this day in and day out, saying that this was a legitimate issue, and that we needed to do something about it. And on the other hand, you had two or three guys who went around to conferences and said, 'Oh, I'm not sure. Oh, maybe there's clouds....' It quickly became apparent that these were private interests who had a stake in the status quo." He refers to it as "emerging industry of nay-sayers."

There's also a discouraged assessment from climate activist looking back over a lack of progress in the early decades. "You want to make an assumption that it's a meritocracy — a good argument will prevail, and it will displace a bad argument. But, what the geniuses at the PR firms who work for these big fossil-fuel companies know is that truth has nothing to do with who wins the argument. If you say something enough times, people will begin to believe it."

Slashdot reader schwit1 shares this report from an automotive blog called The Truth About Cars: A group of German automakers, chemical concerns, and battery producers have announced the joint development of a "battery passport" designed to help government regulators trace the history of the cells. The consortium is funded by the German government and is supposed to work in tandem with new battery regulations that are being prepared by the European Union.

According to the German economic ministry, officially the Federal Ministry for Economic Affairs and Climate Action, the overarching plan is for the EU to mandate traceable hardware be installed in all batteries used in the continent by 2026. Those intended for use in electric vehicles are up first, with the passport scheme also serving to chronicle everything from the vehicle's repair history to where the power cell's raw materials were sourced.
Reuters reports that batteries "could carry a QR code linking to an online database where EV owners, businesses or regulators could access information on the battery's composition." This digital tool should also make it easier to recycle raw materials inside batteries, the government statement said, which would cut dependence on foreign suppliers which control the vast majority of resources, like lithium and nickel, essential for battery production.

Dr. Craig Hunter is a mechanical/aerospace engineer with over 25 years of experience in software development. And now Dixie_Flatline (Slashdot reader #5,077) describes Hunter's latest experiment: Craig Hunter has been running Computational Fluid Dynamics (CFD) benchmarks on Macs for years--he has results going back to 2010 with an Intel Xeon 5650, with the most recent being a 28-core Xeon W from 2019. He has this to say about why he thinks CFD benchmarks are a good test: "As shown above, we see a pretty typical trend where machines get less and less efficient as more and more cores join the computation. This happens because the computational work begins to saturate communications on the system as data and MPI instructions pass between the cores and memory, creating overhead. It's what makes parallel CFD computations such a great real world benchmark. Unlike simpler benchmarks that tend to make CPUs look good, the CFD benchmark stresses the entire system and shows us how things hold up as conditions become more and more challenging."

With just 6 cores, the Mac Studio's M1 Ultra surpasses the 2019 Xeon before literally going off the original chart. He had to double the x-axis just to fit the M1's performance in. Unsurprisingly, he seems impressed:

"We know from Apple's specs and marketing materials that the M1 Ultra has an extremely high 800 GB/sec memory bandwidth and an even faster 2.5 TB/sec interface between the two M1 Max chips that make up the M1 Ultra, and it shows in the CFD benchmark. This leads to a level of CPU performance scaling that I don't even see on supercomputers."

gordm writes: Following appeals from scientists, a Stanford and MIT study showing Diablo Canyon could save California $21 Billion, demand curtailment and a projected power supply shortfall, Gov. Gavin Newsom is now considering keeping the Diablo Canyon nuclear plant open. Diablo Canyon generated 6% of California's total electricity in 2021 and 12% of California's carbon-free electricity.

Elon Musk has tweeted in support of keeping Diablo Canyon open, and in support of keeping European nuclear power plants running. According to the L.A. Times, Newsom said the state would seek out a share of $6 billion in federal funds meant to rescue nuclear reactors facing closure. The money comes from the Biden administration's recently announced effort to rescue nuclear power plants at risk of closing. "The requirement is by May 19 to submit an application, or you miss the opportunity to draw down any federal funds if you want to extend the life of that plant," Newsom said. "We would be remiss not to put that on the table as an option."

A spokesperson for the governor clarified that Newsom still wants to see the facility shut down long term. "It's been six years since PG&E agreed to close the plant near San Luis Obispo, rather than invest in expensive environmental and earthquake-safety upgrades," the report notes. "But Newsom's willingness to consider a short-term reprieve reflects a shift in the politics of nuclear power after decades of public opposition fueled by high-profile disasters such as Chernobyl and Three Mile Island, as well as the Cold War."

Without adding any hardware that actually makes contact with the wearer's face, researchers from Carnegie Mellon University's Future Interfaces Group have modified an off-the-shelf virtual reality headset so that it recreates the sensation of touch in and around a user's mouth, finally fulfilling virtual reality's inevitable one true purpose. Gizmodo reports: The researchers upgraded what appears to be a Meta Quest 2 headset with an array of ultrasonic transducers that are all focused on the user's mouth, and it works without the need for additional accessories, or other hardware set up around the wearer. We've seen ultrasonic transducers used to levitate and move around tiny particles by blasting them with powerful sound waves before, but in this application, they create the feeling of touch on the user's lips, teeth, and even their tongue while their mouth is open. The transducers can do more than just simulate a gentle touch. By pulsing them in specific patterns, they can recreate the feeling of an object sliding or swiping across the lips, or persistent vibrations, such as the continuous splashing of water when leaning down to sip from a virtual drinking fountain.

The researchers have come up with other custom virtual reality experiences that demonstrate how their mouth haptics hardware can introduce more realism, including a hike through a spooky forest where spider webs can be felt across the face, a race where the user can feel the wind in their face, and even virtual eating experiences where food and drinks can be felt inside the mouth. But if and when someone runs with this idea and commercializes the mouth haptics hardware, we're undoubtedly going to see the world's first virtual reality kissing booth realized, among other experiences the researchers are probably wisely tip-toeing around. The paper detailing the work can be found here.

Intel CEO Pat Gelsinger, facing investor skepticism about his turnaround bid, said the company now expects to reach a key technological milestone sooner than planned, helping the storied chipmaker regain its edge. From a report: Under Gelsinger, Intel has been working to restore its leadership in semiconductor process technology -- an effort that requires the company to retool factories. The CEO has previously promised investors that Intel could reach that point by 2025. "Now we think late 2024," he said in an interview with Bloomberg Television.

The remarks follow a weaker-than-expected forecast from Intel that sent its shares on their worst slide in months Friday. A slowdown in personal-computer sales is weighing on its outlook, but some on Wall Street also see Gelsinger's comeback plan as an uphill fight. He's spending tens of billions of dollars to get Intel back on track and expand into new markets, a push that includes new factories in the U.S. and Europe. Intel, the largest producer of computer processors, dominated the chip industry for decades and was synonymous with Silicon Valley innovation. That was based on a foundation of having the most advanced production. How chips are made is crucial to improving their ability to store and hold information, how efficient they are and how costly.

Researchers in Japan have developed a new method for making 5-cm (2-in) wafers of diamond that could be used for quantum memory. The ultra-high purity of the diamond allows it to store a staggering amount of data -- the equivalent of one billion Blu-Ray discs. New Atlas reports: [R]esearchers at Saga University and Adamant Namiki Precision Jewelery Co. in Japan have developed a new method for manufacturing ultra-high purity diamond wafers that are big enough for practical use. With this technique, the team says the resulting diamond wafers measure 5 cm across, and have such immense data density that they can theoretically store the equivalent of a billion Blu-Ray discs. One Blu-Ray can store up to 25 GB (assuming it's single-layered), which would mean this diamond wafer should be able to store a whopping 25 exabytes (EB) of data. The company calls these wafers Kenzan Diamond. The key is that these diamonds have a nitrogen concentration of under three parts per billion (ppb), making them incredibly pure. The researchers say that these are the largest wafers with that level of purity -- most others only get to 4 mm2 (0.006 in2) at most.

Achieving this requires a new manufacturing technique. Diamond wafers are made by growing the crystals on a substrate material, and that material is usually a flat surface. The problem is, the diamond can crack under the strain, degrading the quality. In the new process, the team made a relatively simple change -- the substrate surface was shaped like steps, which spreads the strain horizontally and prevents cracking. This allows them to make larger diamond wafers with higher purity. The team hopes to commercialize these diamond wafers in 2023, and in the meantime are already working towards doubling the diameter to 10 cm (4 in).

An anonymous reader quotes a report from Ars Technica: Qualcomm bought a chipmaking startup called Nuvia back in March of 2021, and later that year, the company said it would be using Nuvia's talent and technology to create high-performance custom-designed ARM chips to compete with Apple's processor designs. But if you're waiting for a truly high-performance Windows PC with anything other than an Intel or AMD chip in it, you'll still be waiting for a bit. Qualcomm CEO Christian Amon mentioned during the company's most recent earnings call that its high-performance chips were on track to land in consumer devices "in late 2023."

Qualcomm still plans to sample chips to its partners later in 2022, a timeframe it has mentioned previously and has managed to stick to. A gap between sampling and mass production is typical, giving Qualcomm time to work out bugs and improve chip yields and PC manufacturers more time to design and build finished products that incorporate the chips. [...] Like Apple's processors, Nuvia's support the ARM instruction set but don't use off-the-shelf ARM Cortex CPU designs. These processor cores have been phenomenally successful in commodity SoCs that power everything from Android phones to smart TVs, and they helped popularize the practice of combining large, high-performance CPU cores and small, high-efficiency CPU cores together in the same design. But they rarely manage to top the performance charts, something that's especially noticeable when they're running x86 code on Windows with a performance penalty.

Meet Pixy, Snap's little flying companion. Pixy is a mini drone that can act as a camera sidekick when you can't ask someone to take a video of you. It'll be available in the U.S. and in France for $229.99. From a report: "Today, we're taking the power and magic of the Snap Camera -- the spontaneity, the joy, and the freedom -- to new heights. A new camera to match the limitless potential of your imagination. Meet Pixy, the world's friendliest flying camera. It's a pocket-sized, free-flying sidekick for adventures big and small," Snap CEO Evan Spiegel said during the Snap Partner Summit keynote. Pixy isn't your average drone as there is no controller and no SD card. It feels like the company has optimized the device so that it's easy to pick up and get started. There's a button to activate the device and a camera dial to select the flying mode. Pixy captures 2.7k videos and 12MP photos. It's very lightweight as it only weighs 101g with the replaceable battery. On a single charge, you can capture five to eight flights.

After Dell's new Compression Attached Memory Module (CAMM) leaked out last week, several tech sites led many to believe that the company was taking a path to "lock out users upgrades." However, according to PCWorld citing both the person who designed and patented the CAMM standard, as well as the product manager of the first Dell Precision laptop to feature it, "the intent of the new memory module standard is to head-off looming bandwidth ceilings in the current SO-DIMM designs." They claim that CAMM could increase performance, improve reliability, aid user upgrades, and eventually lower costs too. From the report: Most of the internet hot takes last week, however, reacted to CAMM being proprietary, which is typically viewed as a method to lock people into buying upgrades only from one company. Dell officials, however, insist that's not the case at all. "One of the tenants of the PC industry is standards," said Dell's Tom Schnell, the Senior Distinguished Engineer who designed much of it. "We believe in that; we put standards into our products. We're not keeping it to ourselves, we hope it becomes the next industry standard."

Schnell said that Dell isn't making the modules and has worked with memory companies as well as Intel on this. In the future, a person with a CAMM-equipped laptop will be able to buy RAM from any third party and install it in the laptop. Yes, initially, Dell will likely be the only place to get CAMM upgrades, but that should change as the standard scales up and is adopted by other PC makers. The new memory modules are also built using commodity DRAMs just like conventional SO-DIMMs.

In fact, Dell points out, it's not even "proprietary" on its own laptops. The first Precision workstations that come with CAMM will also eventually be offered with conventional SO-DIMMs using an interposer. Mano Gialusis, product manager for Precision workstations, said the interposer option goes into the same CAMM mount, too. With CAMM now a reality, Dell's next step is to get it in front of JEDEC, the memory standards organization, to make it available to others, he said. Why not create a standard from scratch? Schnell said its far easier to get a standard minted once it's proven to work rather than trying to simply create something anew every time. The report goes on to say that Dell does hold patents on the CAMM design "and there will be royalties," but "no standard can go forward through JEDEC unless the licensing is not anti-competitive, is reasonably priced, and cannot discriminate against a company."

An anonymous reader quotes a report from Phys.Org: Don't be fooled by the name. While 3D printers do print tangible objects (and quite well), how they do the job doesn't actually happen in 3D, but rather in regular old 2D. Working to change that is a group of former and current researchers from the Rowland Institute at Harvard. [...] The researchers present a method to help the printers live up to their names and deliver a "true" 3D form of printing. In a new paper in Nature, they describe a technique of volumetric 3D printing that goes beyond the bottom-up, layered approach. The process eliminates the need for support structures because the resin it creates is self-supporting.

The key component in their novel design is turning red light into blue light by adding what's known as an upconversion process to the resin, the light reactive liquid used in 3D printers that hardens into plastic. In 3D printing, resin hardens in a flat and straight line along the path of the light. Here, the researchers use nano capsules to add chemicals so that it only reacts to a certain kind of light -- a blue light at the focal point of the laser that's created by the upconversion process. This beam is scanned in three dimensions, so it prints that way without needing to be layered onto something. The resulting resin has a greater viscosity than in the traditional method, so it can stand support-free once it's printed.

"We designed the resin, we designed the system so that the red light does nothing," Congreve said. "But that little dot of blue light triggers a chemical reaction that makes the resin harden and turn into plastic. Basically, what that means is you have this laser passing all the way through the system and only at that little blue do you get the polymerization, [only there] do you get the printing happening. We just scan that blue dot around in three dimensions and anywhere that blue dot hits it polymerizes and you get your 3D printing." The researchers used their printer to produce a 3D Harvard logo, Stanford logo, and a small boat, a standard yet difficult test for 3D printers because of the boat's small size and fine details like overhanging portholes and open cabin spaces.

An anonymous reader quotes a report from Peoples Dispatch: Mexico has officially nationalized its lithium industry. On April 21, the bill, proposed by President Andres Manuel Lopez Obrador (AMLO), that modified the mining law to give the state the exclusive right to explore, exploit and use the valuable metal entered into force. According to the law, published in the Official Gazette of the Federation, the executive or the president now has 90 days to create a decentralized state company that will deal with all lithium-related matters. [...] The new mining law recognizes lithium as a heritage of the nation, and reserves it for the benefit of the people of Mexico. It elevates lithium to the category of "strategic mineral," and prohibits granting concessions, licenses, contracts, permits, assignments or authorizations for its exploitation to private corporations.

The president emphasized that lithium is a strategic element for the development of the nation, and its effective exploitation can contribute to economic growth. He said that his administration would work to develop necessary technology to take the best advantage of their lithium, ensuring that it does not harm the health of the population, the environment, or the rights of Indigenous people. He also took the opportunity to reiterate that his administration would review all lithium contracts. He requested that the shareholders and managers of the companies and corporations begin to establish a dialogue with their legal representatives. There is only one lithium mine in Mexico, operated by Chinese firm Ganfeng Lithium, which is slated to produce 35,000 tons of the metal per year starting in 2023. In the coming days, it will be discussed if that will be taken over by the government.

Meanwhile, the right-wing opposition criticized nationalization of lithium. Some legislators from the opposition National Action Party (PAN) and Institutional Revolutionary Party (PRI), who voted against the reform, said that it would severely affect the development in the mining of the metal, arguing that the Mexican government has no experience in mining lithium. Others criticized that it violated the United States-Mexico-Canada Agreement and would bring trade tensions. Nevertheless, the people of Mexico have expressed their approval of the president and his policies. A number of social organizations and trade unions have praised the president and the ruling center-left MORENA party, recalling that the nationalization of lithium in Bolivia during former president Evo Morales' rule helped the country achieve high levels of economic and social growth. "Lithium is considered an important resource due to its importance for the development of batteries used for electric cars," notes the report. "According to data from the US Geological Survey, Mexico has 1.7 million tons of lithium mining reserves."
