"Chinese company Betavolt has announced an atomic energy battery for consumers with a touted 50-year lifespan," reports Tom's Hardware: The Betavolt BV100 will be the first product to launch using the firm's new atomic battery technology, constructed using a nickel -63 isotope and diamond semiconductor material. Betavolt says that its nuclear battery will target aerospace, AI devices, medical, MEMS systems, intelligent sensors, small drones, and robots — and may eventually mean manufacturers can sell smartphones that never need charging...

[T]he BV100, which is in the pilot stage ahead of mass production, doesn't offer a lot of power. This 15 x 15 x 5mm battery delivers 100 microwatts at 3 volts. It is mentioned that multiple BV100 batteries can be used together in series or parallel depending on device requirements. Betavolt also asserts that it has plans to launch a 1-watt version of its atomic battery in 2025. The new BV100 is claimed to be a disruptive product on two counts. Firstly, a safe miniature atomic battery with 50 years of maintenance-free stamina is a breakthrough. Secondly, Betavolt claims it is the only company in the world with the technology to dope large-size diamond semiconductor materials, as used by the BV100. It is using its 4th Gen diamond semiconductor material here...

[T]he Betavolt BV100 is claimed to be safe for consumers and won't leak radiation even if subjected to gunshots or puncture... Betavolt's battery uses a nickel -63 isotope as the energy source, which decays to a stable isotope of copper. This, plus the diamond semiconductor material, helps the BV100 operate stably in environments ranging from -60 to 120 degrees Celsius, according to the firm...

Betavolt will be well aware of devices with a greater thirst for power and teases that it is investigating isotopes such as strontium- 90, promethium- 147, and deuterium to develop atomic energy batteries with higher power levels and even longer service lives — up to 230 years.

Restrictive US policies limiting advanced chip exports to China have done little to dampen Qualcomm's enthusiasm for the world's second-largest economy. From a report: In an interview at CES 2024 in Las Vegas, CEO Cristiano Amon expressed confidence about Qualcomm's business in the country, its largest market by revenue. "If you have a leading technology, you're going to have a big business in China," he said. The San Diego-based firm finds itself in a difficult situation, as the White House and Congress ramp up a pressure campaign to curb the sale of US chips and chipmaking tools to China, citing national security concerns. The Biden administration has argued that China's access to advanced semiconductors could aid military advancements.

Meanwhile, in China, government agencies and state-owned firms have widened their ban on Apple's iPhones for employees. Qualcomm is one of Apple's biggest suppliers. China remains the largest semiconductor market in the world, with sales in the country accounting for one-third of the global market, according to the Semiconductor Industry Association.

Security researchers warned Apple as early as 2019 about vulnerabilities in its AirDrop wireless sharing function that Chinese authorities claim they recently used to track down users of the feature, the researchers told CNN, in a case that experts say has sweeping implications for global privacy. From a report: The Chinese government's actions targeting a tool that Apple customers around the world use to share photos and documents -- and Apple's apparent inaction to address the flaws -- revive longstanding concerns by US lawmakers and privacy advocates about Apple's relationship with China and about authoritarian regimes' ability to twist US tech products to their own ends.

AirDrop lets Apple users who are near each other share files using a proprietary mix of Bluetooth and other wireless connectivity without having to connect to the internet. The sharing feature has been used by pro-democracy activists in Hong Kong and the Chinese government has cracked down on the feature in response. A Chinese tech firm, Beijing-based Wangshendongjian Technology, was able to compromise AirDrop to identify users on the Beijing subway accused of sharing "inappropriate information," judicial authorities in Beijing said this week. Although Chinese officials portrayed the exploit as an effective law enforcement technique, internet freedom advocates are urging Apple to address the issue quickly and publicly.

U.S. software giant Ivanti has confirmed that hackers are exploiting two critical-rated vulnerabilities affecting its widely-used corporate VPN appliance, but said that patches won't be available until the end of the month. From a report: Ivanti said the two vulnerabilities -- tracked as CVE-2023-46805 and CVE-2024-21887 -- were found in its Ivanti Connect Secure software. Formerly known as Pulse Connect Secure, this is a remote access VPN solution that enables remote and mobile users to access corporate resources over the internet. Ivanti said it is aware of "less than 10 customers" impacted so far by the "zero day" vulnerabilities, described as such given Ivanti had zero time to fix the flaws before they were maliciously exploited.

An anonymous reader quotes a report from the New York Times: When Microsoft opened an advanced research lab in Beijing in 1998, it was a time of optimism about technology and China. The company hired hundreds of researchers for the lab, which pioneered Microsoft's work in speech, image and facial recognition and the kind of artificial intelligence that later gave rise to online chatbots likeChatGPT. The Beijing operation eventually became one of the most important A.I. labs in the world. Bill Gates, Microsoft's co-founder, called it an opportunity to tap China's "deep pool of intellectual talent." But as tensions between the United States and China have mounted over which nation will lead the world's technological future, Microsoft's top leaders -- including Satya Nadella, its chief executive, and Brad Smith, its president -- have debated what to do with the prized lab for at least the past year, four current and former Microsoft employees said.

The company has faced questions from U.S. officials over whether maintaining a 200-person advanced technologies lab in China is tenable, the people said. Microsoft said it had instituted guardrails at the lab, restricting researchers from politically sensitive work. The company, which is based in Redmond, Wash., said it had also opened an outpost of the lab in Vancouver, British Columbia, and would move some researchers from China to the location. The outpost is a backup if more researchers need to relocate, two people said. The idea of shutting down or moving the lab has come up, but Microsoft's leaders support continuing it in China, four people said. "We are as committed as ever to the lab and the world-class research of this team," Peter Lee, who leads Microsoft Research, a network of eight labs across the world, said in a statement. Using the lab's formal name, he added, "There has been no discussion or advocacy to close Microsoft Research Asia, and we look forward to continuing our research agenda."

A U.S.-born chip technology called RISC-V has become critical to China's ambitions. Washington is debating whether and how to limit the technology. From a report: It evolved from a university computer lab in California to a foundation for myriad chips that handle computing chores. RISC-V essentially provides a kind of common language for designing processors that are found in devices like smartphones, disk drives, Wi-Fi routers and tablets. RISC-V has ignited a new debate in Washington in recent months about how far the United States can or should go as it steadily expands restrictions on exporting technology to China that could help advance its military. That's because RISC-V, which can be downloaded from the internet for free, has become a central tool for Chinese companies and government institutions hoping to match U.S. prowess in designing semiconductors.

Last month, the House Select Committee on the Chinese Communist Party -- in an effort spearheaded by Representative Mike Gallagher, Republican of Wisconsin -- recommended that an interagency government committee study potential risks of RISC-V. Congressional aides have met with members of the Biden administration about the technology, and lawmakers and their aides have discussed extending restrictions to stop U.S. citizens from aiding China on RISC-V, according to congressional staff members. The Chinese Communist Party is "already attempting to use RISC-V's design architecture to undermine our export controls," Representative Raja Krishnamoorthi of Illinois, the ranking Democrat on the House select committee, said in a statement. He added that RISC-V's participants should be focused on advancing technology and "not the geopolitical interests of the Chinese Communist Party."

Arm Holdings, a British company that sells competing chip technology, has also lobbied officials to consider restrictions on RISC-V, three people with knowledge of the situation said. Biden administration officials have concerns about China's use of RISC-V but are wary about potential complications with trying to regulate the technology, according to a person familiar with the discussions. The debate over RISC-V is complicated because the technology was patterned after open-source software, the free programs like Linux that allow any developer to view and modify the original code used to make them. Such programs have prompted multiple competitors to innovate and reduce the market power of any single vendor.

The European climate agency Copernicus said Earth shattered global annual heat records in 2023, flirting with the world's agreed-upon warming threshold of 1.5 degrees Celsius. "On average, global temperatures in 2023 were 1.48 degrees Celsius higher than pre-industrial times," reports the Associated Press. "If annual averages reach above 1.5 degrees Celsius, the effects of global warming could become irreversible, climate scientists say." From the report: The record heat made life miserable and sometimes deadly in Europe, North America, China and many other places last year. But scientists say a warming climate is also to blame for more extreme weather events, like the lengthy drought that devastated the Horn of Africa, the torrential downpours that wiped out dams and killed thousands in Libya and the Canada wildfires that fouled the air from North America to Europe. In a separate Tuesday press event, international climate scientists who calculate global warming's role in extreme weather, the group's leader, Imperial College climate scientist Friederike Otto said "we definitely see in our analysis the strong impact of it being the hottest year."

The World Weather Attribution team only looks at events that affect at least 1 million people or kill more than 100 people. But Otto said her team was overwhelmed with more than 160 of those in 2023, and could only conduct 14 studies, many of them on killer heat waves. "Basically every heat wave that is occurring today has been made more likely and is hotter because of human-induced climate change," she said. [....] Antarctic sea ice hit record low levels in 2023 and broke eight monthly records for low sea ice, Copernicus reported.

Copernicus calculated that the global average temperature for 2023 was about one-sixth of a degree Celsius (0.3 degrees Fahrenheit) warmer than the old record set in 2016. While that seems a small amount in global record-keeping, it's an exceptionally large margin for the new record, [Copernicus Deputy Director Samantha Burgess] said. Earth's average temperature for 2023 was 14.98 degrees Celsius (58.96 degrees Fahrenheit), Copernicus calculated.

According to Bloomberg, Apple's AirDrop feature has been cracked by a Chinese state-backed institution to identify senders who share "undesirable content". MacRumors reports: AirDrop is Apple's ad-hoc service that lets users discover nearby Macs and iOS devices and securely transfer files between them over Wi-Fi and Bluetooth. Users can send and receive photos, videos, documents, contacts, passwords and anything else that can be transferred from a Share Sheet. Apple advertises the protocol as secure because the wireless connection uses Transport Layer Security (TLS) encryption, but the Beijing Municipal Bureau of Justice (BMBJ) says it has devised a way to bypass the protocol's encryption and reveal identifying information.

According to the BMBJ's website, iPhone device logs were analyzed to create a "rainbow table" which allowed investigators to convert hidden hash values into the original text and correlate the phone numbers and email accounts of AirDrop content senders. The "technological breakthrough" has successfully helped the public security authorities identify a number of criminal suspects, who use the AirDrop function to spread illegal content, the BMBJ added. "It improves the efficiency and accuracy of case-solving and prevents the spread of inappropriate remarks as well as potential bad influences," the bureau added.

It is not known if the security flaw in the AirDrop protocol has been exploited by a government agency before now, but it is not the first time a flaw has been discovered. In April 2021, German researchers found that the mutual authentication mechanism that confirms both the receiver and sender are on each other's address book could be used to expose private information. According to the researchers, Apple was informed of the flaw in May of 2019, but did not fix it.

As General Motors prepares to roll out electric versions of its Buicks, "hundreds of Buick dealerships nationwide" are "turning their backs on the storied brand," reports the Boston Globe.

"The move to electric Buicks is one reason so many dealers are giving up their Buick franchises, according to auto industry watchers." They say that smaller, low-volume Buick dealers either can't or won't make the big investments needed to begin selling EVs, especially as sales growth in the sector has cooled and unsold electrics are piling up on dealer lots. "I think there are dealers who are just not confident in the electric vehicle transition and they don't want to have to commit to the investment," said Karl Brauer, executive analyst at online car retailer iSeeCars.com...

Buick has announced its intention to migrate to an all-electric line of cars by the end of the decade. The brand's first EV is set to go on sale this year. But getting ready to sell EVs is a costly proposition. Dealers must purchase new equipment to service the cars and must pay for worker retraining. GM estimates that the upfront cost to dealers will range between $200,000 and $400,000. "If you're in a market where you're not selling a lot of Buicks, investing a lot to sell electric Buicks may not make a good business case," said Mark Schirmer, spokesperson for Cox Automotive, an Atlanta-based automotive marketing company.
While 854,000 Buicks were sold in 1980, just 103,000 were sold in 2022 — down from 207,000 in 2019, according to the article. So in 2022 GM bought out 44 percent of its dealerships (which they say accounted for just 20% of all U.S. Buick sales), with the majority of them still selling other GM brands like Chevrolet and GMC.

But the article also includes some perspective from Robert O'Koniewski, executive vice president of the Massachusetts State Automobile Dealers Association. "The only reason GM has kept the Buick alive is that it's popular in China." That's Buick's biggest market by far, thanks to a 50-50 joint venture it launched in 1997 with government-owned SAIC Motor, China's biggest carmaker. The partnership sold 653,000 Chinese Buicks in 2022.

But that's a big decline from the 926,000 sold in 2020. Brauer said that Chinese consumers are pulling away from the US brand in favor of Chinese companies like BYD, which passed Tesla in the fourth quarter of 2023 to become the world's largest maker of electric vehicles.

Long-time Slashdot reader xetdog shared this report from IEEE Spectrum: High in the Andes mountains where the borders of Argentina, Bolivia, and Chile intersect, white expanses of salt stretch for thousands of kilometers. Under these flats lie reservoirs of brine that contain upwards of 58% of the world's lithium. For decades, producers have extracted that lithium by pumping the water up to the surface and letting it evaporate until the lithium salts become concentrated enough to filter out. The process takes 12 to 18 months, leaving behind piles of waste containing other metals. It also evaporates nearly 2 million liters of local water resources, harming indigenous communities.

To keep up, many companies are now developing processes to chemically or physically filter out lithium from brines and inject the brine back underground. These direct lithium extraction (DLE) technologies take hours instead of months and could double the production of lithium from existing brine operations. Much as shale extraction did for oil, DLE is a "potential game-changing technology for lithium supply," because it could unlock new sources of lithium, according to a recent report by Goldman Sachs. But in contrast to shale's fracking risks, DLE brings environmental benefits, reducing land and water use, and waste...

In China, a handful of commercial projects already use Chinese DLE innovator Sunresin's technology.
More than 12 startups are pursuing new DLE processes, according to the article, "with the intent of commercial production as early as 2025."

And America's Department of Energy is also investing millions of dollars in new DLE tech "to extract lithium from geothermal brines in the U.S., such as the Salton Sea in California, which the National Renewable Energy Laboratory estimates could provide over 24,000 metric tons of lithium a year."

Huawei's newest laptop runs on a chip made by Taiwan Semiconductor Manufacturing Co., a teardown of the device showed, quashing talk of another Chinese technological breakthrough. From a report: The Qingyun L540 notebook contains a 5-nanometer chip made by the Taiwanese company in 2020, around the time US sanctions cut off Huawei's access to the chipmaker, research firm TechInsights found after dismantling the device for Bloomberg News. That counters speculation that Huawei's mainland Chinese chipmaking partner, Semiconductor Manufacturing International Corp., may have achieved a major leap in fabrication technique.

Huawei caused a stir in the US and China last August when it released a smartphone with a 7nm processor made by Shanghai-based SMIC. A teardown by the Canada-based research outfit for Bloomberg News showed the Mate 60 Pro's chip was only a few years behind the cutting edge, a feat that US trade curbs were meant to prevent. That revelation spurred celebration across the Chinese tech scene, and a debate in the US about the effectiveness of sanctions.

China's top diplomat warned the US that decoupling would be "self defeating" as the country set out to implement a recent agreement made between their leaders. From a report: Foreign Minister Wang Yi, speaking on Friday at an event to mark the 45th anniversary of US-China diplomatic relations, cited a slew of initiatives that reflect improved ties including streamlined visas for US travelers, a counternarcotics working group to battle the flow of the synthetic fentanyl to the US, and the sending of pandas to the US by the end of the year. "Any decoupling attempt to stem the tide will only be counterproductive and self defeating," Wang said.

David Meale, deputy chief of mission at the U.S. Embassy in Beijing, joined Friday's event as charge d'affaires with Ambassador Nicholas Burns out of town. Tensions between China and the US started to ease after President Joe Biden and Chinese leader Xi Jinping met in November. The talks resulted in a resumption of high-level military-to-military ties, a promise to collaborate on the fentanyl problem and a commitment to boost interactions between people in the two countries.

An anonymous reader quotes a report from The Verge: Using satellite imagery and AI, researchers have mapped human activity at sea with more precision than ever before. The effort exposed a huge amount of industrial activity that previously flew under the radar, from suspicious fishing operations to an explosion of offshore energy development. The maps were published today in the journal Nature. The research led by Google-backed nonprofit Global Fishing Watch revealed that a whopping three-quarters of the world's industrial fishing vessels are not publicly tracked. Up to 30 percent of transport and energy vessels also escape public tracking. Those blind spots could hamper global conservation efforts, the researchers say. To better protect the world's oceans and fisheries, policymakers need a more accurate picture of where people are exploiting resources at sea.

Until now, Global Fishing Watch and other organizations relied primarily on the maritime Automatic Identification System (AIS) to see what was happening at sea. The system tracks vessels that carry a box that sends out radio signals, and the data has been used in the past to document overfishing and forced labor on vessels. Even so, there are major limitations with the system. Requirements to carry AIS vary by country and vessel type. And it's pretty easy for someone to turn the box off when they want to avoid detection, or cruise through locations where signal strength is spotty. To fill in the blanks, Kroodsma and his colleagues analyzed 2,000 terabytes of imagery from the European Space Agency's Sentinel-1 satellite constellation. Instead of taking traditional optical imagery, which is like snapping photos with a camera, Sentinel-1 uses advanced radar instruments to observe the surface of the Earth. Radar can penetrate clouds and "see" in the dark -- and it was able to spot offshore activity that AIS missed.

Since 2,000 terabytes is an enormous amount of data to crunch, the researchers developed three deep-learning models to classify each detected vessel, estimate their size, and sort out different kinds of offshore infrastructure. They monitored some 15 percent of the world's oceans where 75 percent of industrial activity takes place, paying attention to both vessel movements and the development of stationary offshore structures like oil rigs and wind turbines between 2017 and 2021. While fishing activity dipped at the onset of the covid-19 pandemic in 2020, they found dense vessel traffic in areas that "previously showed little to no vessel activity" in public tracking systems -- particularly around South and Southeast Asia, and the northern and western coasts of Africa.

A boom in offshore energy development was also visible in the data. Wind turbines outnumbered oil structures by the end of 2020. Turbines made up 48 percent of all ocean infrastructure by the following year, while oil structures accounted for 38 percent. Nearly all of the offshore wind development took place off the coasts of northern Europe and China. In the Northeast US, clean energy opponents have tried to falsely link whale deaths to upcoming offshore wind development even though evidence points to vessel strikes being the problem. Oil structures have a lot more vessels swarming around them than wind turbines. Tank vessels are used at times to transport oil to shore as an alternative to pipelines. The number of oil structures grew 16 percent over the five years studied. And offshore oil development was linked to five times as much vessel traffic globally as wind turbines in 2021. "The actual amount of vessel traffic globally from wind turbines is tiny, compared to the rest of traffic," Kroodsma says.

A federal criminal complaint has revealed that state and local agencies in New Jersey bought millions of dollars worth of banned Chinese surveillance cameras. The cameras were purchased from a local company that rebranded the banned equipment made by Dahua Technology, a company that has been implicated in the surveillance of the Uyghur people in Xinjiang. According to 404 Media, "At least $15 million of the equipment was bought using federal COVID relief funds." From the report: The feds charged Tamer Zakhary, the CEO of the New Jersey-based surveillance company Packetalk, with three counts of wire fraud and a separate count of false statements for repeatedly lying to state and local agencies about the provenance of his company's surveillance cameras. Some of the cameras Packetalk sold to local agencies were Dahua cameras that had the Dahua logo removed and the colors of the camera changed, according to the criminal complaint.

Dahua Technology is the second largest surveillance camera company in the world. In 2019, the U.S. government banned the purchase of Dahua cameras using federal funds because their cameras have "been implicated in human rights violations and abuses in the implementation of China's campaign of repression, mass arbitrary detention, and high-technology surveillance against Uyghurs, Kazakhs, and other members of Muslim minority groups in Xingjiang." The FCC later said that Dahua cameras "pose an unacceptable risk to U.S. national security." Dahua is not named in the federal complaint, but [404 Media's Jason Koebler] was able to cross-reference details in the complaint with Dahua and was able to identify specific cameras sold by Packetalk to Dahua's product.

According to the FBI, Zakhary sold millions of dollars of surveillance equipment, including rebranded Dahua cameras, to agencies all over New Jersey despite knowing that the cameras were illegal to sell to public agencies. Zakhary also specifically helped two specific agencies in New Jersey (called "Victim Agency-1" and "Victim Agency-2" in the complaint) justify their purchases using federal COVID relief money from the CARES Act, according to the criminal complaint. The feds allege, essentially, that Zakhary tricked local agencies into buying banned cameras using COVID funds: "Zakhary fraudulently misrepresented to the Public Safety Customers that [Packetalk's] products were compliant with Section 889 of the John S. McCain National Defense Authorization Act for 2019 [which banned Dahua cameras], when, in fact, they were not," the complaint reads. "As a result of Zakhary's fraudulent misrepresentations, the Public Safety Customers purchased at least $35 million in surveillance cameras and equipment from [Packetalk], over $15 million of which was federal funds and grants."

"To prevent disinformation from eroding democratic values worldwide, the U.S. must establish a global watermarking standard for text-based AI-generated content," writes retired U.S. Army Col. Joe Buccino in an opinion piece for The Hill. While President Biden's October executive order requires watermarking of AI-derived video and imagery, it offers no watermarking requirement for text-based content. "Text-based AI represents the greatest danger to election misinformation, as it can respond in real-time, creating the illusion of a real-time social media exchange," writes Buccino. "Chatbots armed with large language models trained with reams of data represent a catastrophic risk to the integrity of elections and democratic norms."

Joe Buccino is a retired U.S. Army colonel who serves as an A.I. research analyst with the U.S. Department of Defense Defense Innovation Board. He served as U.S. Central Command communications director from 2021 until September 2023. Here's an excerpt from his report: Watermarking text-based AI content involves embedding unique, identifiable information -- a digital signature documenting the AI model used and the generation date -- into the metadata generated text to indicate its artificial origin. Detecting this digital signature requires specialized software, which, when integrated into platforms where AI-generated text is common, enables the automatic identification and flagging of such content. This process gets complicated in instances where AI-generated text is manipulated slightly by the user. For example, a high school student may make minor modifications to a homework essay created through Chat-GPT4. These modifications may drop the digital signature from the document. However, that kind of scenario is not of great concern in the most troubling cases, where chatbots are let loose in massive numbers to accomplish their programmed tasks. Disinformation campaigns require such a large volume of them that it is no longer feasible to modify their output once released.

The U.S. should create a standard digital signature for text, then partner with the EU and China to lead the world in adopting this standard. Once such a global standard is established, the next step will follow -- social media platforms adopting the metadata recognition software and publicly flagging AI-generated text. Social media giants are sure to respond to international pressure on this issue. The call for a global watermarking standard must navigate diverse international perspectives and regulatory frameworks. A global standard for watermarking AI-generated text ahead of 2024's elections is ambitious -- an undertaking that encompasses diplomatic and legislative complexities as well as technical challenges. A foundational step would involve the U.S. publicly accepting and advocating for a standard of marking and detection. This must be followed by a global campaign to raise awareness about the implications of AI-generated disinformation, involving educational initiatives and collaborations with the giant tech companies and social media platforms.

In 2024, generative AI and democratic elections are set to collide. Establishing a global watermarking standard for text-based generative AI content represents a commitment to upholding the integrity of democratic institutions. The U.S. has the opportunity to lead this initiative, setting a precedent for responsible AI use worldwide. The successful implementation of such a standard, coupled with the adoption of detection technologies by social media platforms, would represent a significant stride towards preserving the authenticity and trustworthiness of democratic norms.

Retired officers and departing defense officials are flocking to investment firms that are pushing the government to provide more money to defense-technology startups. The New York Times: When Defense Secretary Lloyd J. Austin III and other top officials assembled for an event this month at the Ronald Reagan Presidential Library, they walked into a lesson in how the high-stakes world of Pentagon lobbying is being altered by the rise of defense technology startups. Inside, at this elite gathering near Los Angeles of senior leaders from government and the arms industry, was a rapidly growing group of participants: former Pentagon officials and military officers who have joined venture capital firms and are trying to use their connections in Washington to cash in on the potential to sell a new generation of weapons.

They represent a new path through the revolving door that has always connected the Defense Department and the military contracting business. Retiring generals and departing top Pentagon officials once migrated regularly to the big established weapons makers like Lockheed Martin and Boeing. Now they are increasingly flocking to venture capital firms that have collectively pumped billions of dollars into Silicon Valley-style startups offering the Pentagon new war-fighting tools like autonomous killer drones, hypersonic jets and space surveillance equipment.

This new route to the private sector is one indicator of the ways in which the United States is trying to become more agile in harnessing technological advances to maintain military superiority over China and other rivals. But the close ties between venture capital firms and Defense Department decision makers have also put a new twist on long-running questions about industry access and influence at a time when the Pentagon is under pressure to rethink how it allocates its huge procurement budget.

Every large smartphone maker except Apple is betting that "foldable" phones will help revive a lacklustre mobile market, despite the devices still largely failing to attract mainstream consumers. From a report: Foldables, which have a screen that opens like a book or compact mirror, barely exceed a 1 per cent market share of all smartphones sold globally almost five years after they were first introduced. But Samsung has doubled down on the product, investing heavily in marketing this year. In July, the Korean group released its 5G Galaxy Z series. The world's largest smartphone manufacturer points to estimates from Counterpoint Research that foldable devices may surpass a third of all smartphones costing more than $600 by 2027.

Other handset makers such as Motorola, China's Huawei and its spin-off Honor are also pinning their hopes on the product helping to revive a market that suffered its worst year for more than a decade. "This is the year people [in the industry] really dived in," said Ben Wood, an analyst at CCS Insight. "Everybody now is betting on this, except Apple." The iPhone-maker has yet to show any interest in the category, though patent filings suggest it may one day introduce an iPad that folds in half. Every other big smartphone maker has followed Samsung into the market, including Google's Pixel Fold and Chinese alternatives from Huawei, Oppo and Xiaomi.

India launched its first satellite on Monday to study black holes as it seeks to deepen its space exploration efforts ahead of an ambitious crewed mission next year. From a report: The spacecraft, named X-ray Polarimeter Satellite, was propelled into an orbit of 350 kilometers from an island near India's main spaceport of Sriharikota, off the southern state of Andhra Pradesh, according to S. Somanath, chairman of the Indian Space Research Organisation. The satellite, weighing about 470 kilograms, will carry out research on X-rays emanating from around 50 celestial objects with the help of two payloads built by ISRO and a Bengaluru-based research institute.

NASA launched a similar mission, the Imaging X-ray Polarimetry Explorer, in 2021 to answer questions such as why black holes spin and build on the findings of its flagship telescope Chandra X-ray Observatory that blasted off more than two decades ago. China's National Space Administration launched the country's first X-ray space telescope to observe black holes, pulsars and gamma-ray bursts in 2017.

Forbes writes: "I am not sure there could have been a more ignominious end to the DCEU." Aquaman 2 opened with $27.7 million domestically, well under half the $67.8 million opening for the original Aquaman. But it's the overall box office totals that are especially dire, as the film has made just over $138.5 million worldwide. That is about 12% of Aquaman 1's final total of $1.1 billion in 2018, where it is the DCEU's highest grossing entry.

The counter to this is that it perhaps is too soon to run these numbers, as it just came out right? Well, a few extra factors to consider. It is already out in a ton of major markets, so there are relatively few potential surges that can still happen outside places like Korea and New Zealand, which can only add so much. Most importantly Aquaman 2 has already launched in China, where it made $30 million in its opening, again, far below the original's opening at $93 million there, doing even worse there than domestically, in context. Aquaman 1 went on to make $292 million in China, a figure Aquaman 2 will not come within a mile of. Next, what DC, and many blockbusters, have been doing lately are these incredibly short theatrical windows, so the clock is ticking quickly...

Of course this is not exclusive to DC, as we have an extremely direct comparison over at Marvel with The Marvels, which at a $205.6 million global gross, the final figure, that is 18% of Captain Marvel's $1.13 billion total. Aquaman 2 has the advantage of being a true sequel, not a team-up piece from other TV shows you theoretically needed to watch beforehand, but it also has the disadvantage of being the last dying gasp of the DCEU coming after a string of other high profile box office failures from Shazam 2 to Blue Beetle.

There was really no way it was going to avoid its fate, even if it did review well (which it didn't, as at 35% on Rotten Tomatoes, it's one of the DCEU's lowest rated films).

"[F]or years it was written off," writes CNN. " 'The economics were just way out,' said Martin Soltau, CEO of the UK-based company Space Solar.

"That may now be changing as the cost of launching satellites falls sharply, solar and robotics technology advances swiftly, and the need for abundant clean energy to replace planet-heating fossil fuels becomes more urgent." There's a "nexus of different technologies coming together right now just when we need it," said Craig Underwood, emeritus professor of spacecraft engineering at the University of Surrey in the U.K. The problem is, these technologies would need to be deployed at a scale unlike anything ever done before... "The big stumbling block has been simply the sheer cost of putting a power station into orbit." Over the last decade, that has begun to change as companies such as SpaceX and Blue Origin started developing reusable rockets. Today's launch costs at around $1,500 per kilogram are about 30 times less than in the Space Shuttle era of the early 1980s.

And while launching thousands of tons of material into space sounds like it would have a huge carbon footprint, space solar would likely have a footprint at least comparable to terrestrial solar per unit of energy, if not a smaller, because of its increased efficiency as sunlight is available nearly constantly, said Mamatha Maheshwarappa, payload systems lead at UK Space Agency. Some experts go further. Underwood said the carbon footprint of space-based solar would be around half that of a terrestrial solar farm producing the same power, even with the rocket launch...

There is still a huge gulf between concept and commercialization. We know how to build a satellite, and we know how to build a solar array, Maheshwarappa said. "What we don't know is how to build something this big in space..." Scientists also need to figure out how to use AI and robotics to construct and maintain these structures in space. "The enabling technologies are still in a very low technology readiness," Maheshwarappa said. Then there's regulating this new energy system, to ensure the satellites are built sustainably, there's no debris risk, and they have an end-of-life plan, as well as to determine where rectenna sites should be located. Public buy-in could be another huge obstacle, Maheshwarappa said. There can be an instinctive fear when it comes to beaming power from space.

But such fears are unfounded, according to some experts. The energy density at the center of the rectenna would be about a quarter of the midday sun. "It is no different than standing in front of a heat lamp," Hajimiri said.
The article argues that governments and companies around the world "believe there is huge promise in space-based solar to help meet burgeoning demand for abundant, clean energy and tackle the climate crisis." And they cite several specific examples:

• In 2020 the U.S. Naval Research Lab launched a module on an orbital test vehicle, to test solar hardware in space conditions.

• This year Caltech electrical engineering professor led a team that successfully launched a 30-centimeter prototype equipped with transmitters — and successfully beamed detectable energy down to earth.

• In June the U.K. government announced over $5 million in funding to universities and tech companies "to drive forward innovation" in the space-based solar sector.

• The U.S. Air Force Research Lab plans to launch a small demonstrator in 2025.

• Europe's its Solaris program aims to prove "the technical and political viability of space-based solar, in preparation for a possible decision in 2025 to launch a full development program."

• One Chinese spacecraft designer and manufacturer hopes to send a solar satellite into low orbit in 2028 and high orbit by 2030, according to a 2022 South China Morning News report.
