Is It Possible to Beam Solar Power From Outer Space?

Sat, 12/30/2023 - 1:34pm
"[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.

Fewer People Are Posting on Social Media. 50% Could Leave Or Limit Interactions Within 2 Years

Sat, 12/30/2023 - 12:34pm
"Billions of people" uses social media every month, notes the Wall Street Journal.. But "fewer and fewer are actually posting." Instead they're favoring "a more passive experience, surveys of users and research from data-analytics firms say." In an October report from data-intelligence company Morning Consult, 61% of U.S. adult respondents with a social-media account said they have become more selective about what they post. The reasons are varied: People say they feel they can't control the content they see. They have become more protective about sharing their lives online. They also say the fun of social media has fizzled. This lurker mentality is widespread, across Meta Platforms' Instagram and Facebook along with X and TikTok.... In a survey conducted in the U.S. this summer, research firm Gartner found more than half of respondents believed the quality of social media has declined in the past five years. They cited misinformation, toxicity and the proliferation of bots as reasons it has gotten worse. "The less you trust social-media brands, the less of a good experience you're having," says Gartner analyst Emily Weiss. Users are less likely to share opinions or insight into their lives since the community they are looking for isn't there, she adds. Ads and suggested posts have also sucked the joy out of apps, some users say... The algorithmic spotlight on creators and their hyper-curated content has made some users feel insecure and less likely to share their own photos and videos, says Kevin Tran, media and entertainment analyst at Morning Consult. In turn, some now think of social apps more as sources of entertainment, like YouTube or Netflix. Gartner estimates that 50% of users will either abandon or significantly limit their interactions with social media in the next two years. Any threat to interacting is a threat to business, the article notes, adding "The companies are responding." They are investing in more private user experiences like messaging, and making interactions more secure. And encouraging people to post to a more intimate audience — as with Instagram's recently expanded Close Friends feature... Meta responded to user complaints, saying it would continue to work on improving recommendations to help creators reach more people. The company added a snooze button that pauses suggested posts for 30 days at a time, and chronological feeds that temporarily only show posts from accounts people follow... Meta began shifting its resources toward messaging, including efforts to enable end-to-end encryption by default across all of its messaging services... TikTok has also shown signs of investing more in the messaging portion of its app, nudging users to chat with people they haven't messaged in a while. When the Wall Street Journal posted their article on Threads, Adam Mosseri (head of Instagram) responded that "People are sharing to feeds less, but to Stories more," and "even more still" in Messages ("even photos and videos"). Mosseri also said that Instagram's Notes feature — basically a post where you cab specify a smaller subset of your followers to see it — "have quickly become a big thing, particularly for young people. "So it's no so much that people are sharing less," Mosseri argued, "but rather than they're sharing differently."

Massive Waves Pound Some California Coast Cities, Causing Floods and Injuries

Sat, 12/30/2023 - 11:34am
CNN describes them as "towering waves," driven into California's coastline by powerful storms and "posing a significant risk to people and structures along the coast." Monstrous, 20-foot-plus waves on Thursday crashed over seawalls and swept away and injured several people, forced rescues and sent a damaging surge of water through coastal California streets. Dangerous waves continued to slam the coast on Friday, forcing beaches to close. All Ventura County beaches will be closed through New Year's Eve because of the 15- to 20-foot waves expected along the central and Southern California coasts through Saturday evening... Sea levels have risen along most of the California coastline over the past century, NOAA data shows, as global temperatures climb and melt glaciers and ice sheets. Higher sea levels are making coastal flooding events worse and will continue to do so in the future. The first round of dangerous waves hit alongside high tide Thursday morning. Several people were injured by a huge wave that slammed into Pierpont in the Ventura Beach area... Nearly 20 people were briefly swept away in the incident and eight people were taken to the hospital, Ventura officials said. One bystander even filmed what CNN calls a"monster" wave, "the surge sweeping people and vehicles down the street... The massive waves pummeling the coastline, reeking havoc, flooding streets and businesses." CNN's report also includes footage from nearly 300 miles north, showing a wave flooding a beachfront restaurant's courtyard in Santa Cruz, California. ("I just feel bad for the restaurants," says one local. "I know they just went through renovations from the last time this happened.") CNN's original article notes the sheriff's office there briefly issued an evacuation warning for some areas for part of Thursday, including one "where seawater filled beachside roadways and pushed against some homes, CNN affiliate KION reported." And CNN's video report concludes by noting that "Parts of the California coast could see towering waves through the weekend, coastal flood and high surf alerts stretching from the southern border to the Bay Area."

That Chinese Spy Balloon Used an American ISP to Communicate, Say US Officials

Sat, 12/30/2023 - 10:24am
NBC News reports that the Chinese spy balloon that flew across the U.S. in February "used an American internet service provider to communicate, according to two current and one former U.S. official familiar with the assessment." it used the American ISP connection "to send and receive communications from China, primarily related to its navigation." Officials familiar with the assessment said it found that the connection allowed the balloon to send burst transmissions, or high-bandwidth collections of data over short periods of time. The Biden administration sought a highly secretive court order from the federal Foreign Intelligence Surveillance Court to collect intelligence about it while it was over the U.S., according to multiple current and former U.S. officials. How the court ruled has not been disclosed. Such a court order would have allowed U.S. intelligence agencies to conduct electronic surveillance on the balloon as it flew over the U.S. and as it sent and received messages to and from China, the officials said, including communications sent via the American internet service provider... The previously unreported U.S. effort to monitor the balloon's communications could be one reason Biden administration officials have insisted that they got more intelligence out of the device than it got as it flew over the U.S. Senior administration officials have said the U.S. was able to protect sensitive sites on the ground because they closely tracked the balloon's projected flight path. The U.S. military moved or obscured sensitive equipment so the balloon could not collect images or video while it was overhead. NBC News is not naming the internet service provider, but says it denied that the Chinese balloon had used its network, "a determination it said was based on its own investigation and discussions it had with U.S. officials." The balloon contained "multiple antennas, including an array most likely able to collect and geolocate communications," according to reports from a U.S. State Depratment official cited by NBC News in February. "It was also powered by enormous solar panels that generated enough power to operate intelligence collection sensors, the official said. Reached for comment this week, a spokesperson for the Chinese Embassy in Washington told NBC News that the balloon was just a weather balloon that had accidentally drifted into American airspace.

Novel Helmet Liner 30 Times Better At Stopping Concussions

Sat, 12/30/2023 - 8:00am
An anonymous reader quotes a report from New Atlas: Researchers have developed a new, lightweight foam made from carbon nanotubes that, when used as a helmet liner, absorbed the kinetic energy caused by an impact almost 30 times better than liners currently used in US military helmets. The foam could prevent or significantly reduce the likelihood of concussion in military personnel and sportspeople. Among sportspeople and military vets, traumatic brain injury (TBI) is one of the major causes of permanent disability and death. Injury statistics show that the majority of TBIs, of which concussion is a subtype, are associated with oblique impacts, which subject the brain to a combination of linear and rotational kinetic energy forces and cause shearing of the delicate brain tissue. To improve their effectiveness, helmets worn by military personnel and sportspeople must employ a liner material that limits both. This is where researchers from the University of Wisconsin-Madison come in. Determined to prevent -- or lessen the effect of -- TBIs caused by knocks to the body and head, they've developed a new lightweight foam material for use as a helmet liner. For the current study, Thevamaran built upon his previous research into vertically aligned carbon nanotube (VACNT) foams -- carefully arranged layers of carbon cylinders one atom thick -- and their exceptional shock-absorbing capabilities. Current helmets attempt to reduce rotational motion by allowing a sliding motion between the wearer's head and the helmet during impact. However, the researchers say this movement doesn't dissipate energy in shear and can jam when severely compressed following a blow. Instead, their novel foam doesn't rely on sliding layers. VACNT foam sidesteps this shortcoming via its unique deformation mechanism. Under compression, the VACNTs undergo collective sequentially progressive buckling, from increased compliance at low shear strain levels to a stiffening response at high strain levels. The formed compression buckles unfold completely, enabling the VACNT foam to accommodate large shear strains before returning to a near initial state when the load is removed. The researchers found that at 25% precompression, the foam exhibited almost 30 times higher energy dissipation in shear -- up to 50% shear strain -- than polyurethane-based elastomeric foams of similar density. The study has been published in the journal Experimental Mechanics.

Documentarians Secure Original 'ReBoot' Master Tapes, But Need Help To Play Them

Sat, 12/30/2023 - 5:00am
"Predating even Toy Story, ReBoot was the first 3D animated television show," writes longtime Slashdot reader sandbagger, sharing a new report from Global News. "The master tapes have been located in storage but the hardware needed to play the 1990s-era media has yet to be located." From the report: Produced in Vancouver by Mainframe Entertainment, it aired on YTV between 1994 and 2001, and decades later still has a committed fan base. Among those super fans are Jacob Weldon and Raquel Lin, a B.C. duo now crafting a documentary about the creation of the show and its impact in the film and TV world. Weldon said he wants to see ReBoot recognized for its place in the evolution of computer animation -- recognition he said it rarely gets. When ReBoot was finally cancelled -- cut short in its fourth and final season -- its protagonists were left in peril and the show ended on a cliffhanger. It's another factor that Lin and Weldon say has helped immortalize the show and has helped fans hoping for a revival that might finally explain the characters' fate. Earlier this month, the documentary also got a potential major boost. Mainframe allowed Lin and Weldon to come to the studio to look for the show's original master tapes, recordings some believed might have been permanently lost. They struck gold. "They had boxes upon boxes upon boxes, hundreds of tapes," Lin said. "It's original resolution, original frame rate, uncompressed. If we could get a deck to play these, they would look beautiful," Weldon said. Finding that deck, however, is the pair's next major challenge. The recordings are on a rare digital tape format called D1, a technology that Weldon said was cutting edge and rare when Mainframe was using it. It's even harder to find today, and even Mainframe doesn't have the equipment to play the tapes back. Weldon and Lin have since put out a call on social media for a working Bosch BTS D1 deck that would allow them to play the tapes, and incorporate them into their documentary. "I can't tell you how many people have called us, DM'd us, emailed us -- people from all over the world," Lin said. While the pair still haven't secured the deck, they're aiming to release their documentary by next summer. They're hoping it will help renew interest in the show, introduce it to new generations and perhaps see it get new life on a streaming platform.

SpaceX Wows With a Double Header of Final 2023 Rocket Launches

Sat, 12/30/2023 - 2:00am
SpaceX on Thursday launched two rockets into orbit, only three hours apart, bringing its total number of launches to 98 in 2023. Space.com reports: The first SpaceX mission to take to the skies Thursday (Dec. 28) was a Falcon Heavy rocket carrying the U.S. military's secretive X-37B space plane, designed mission USSF-52. That blasted off from NASA's Kennedy Space Center in Florida at 8:07 p.m. EST (0107 GMT on Dec. 29). This marked the second Falcon Heavy flight of 2023. Second up on the launch docket for Thursday, hours later, was a Falcon 9 liftoff carrying 23 SpaceX Starlink units to low Earth orbit from nearby Cape Canaveral Space Force Station. This launch took place at 11:01 p.m. EST (0401 GMT on Dec. 29). This was SpaceX's 98th and final launch of 2023, and the 96th flight for a Falcon 9 rocket this year. SpaceX's 97th launch overall for this year marked the seventh flight for X-37B, but the first time the space plane hitched a lift atop a Falcon Heavy rocket. The X-37B/Falcon Heavy launch had been scrubbed several times previously due to bad weather and an issue with ground equipment. The launch of 23 Starlink broadband satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida that capped off 2023 was also the 96th launch of a Falcon 9 rocket during this year. SpaceX's next launch is targeted for Jan. 2, 2024 and will see a further 21 Starlink satellites lift to orbit to join the over 5,500 internet supplying units currently orbiting Earth.

AI-Created 'Virtual Influencers' Are Stealing Business From Humans

Fri, 12/29/2023 - 10:30pm
An anonymous reader quotes a report from the Financial Times: Pink-haired Aitana Lopez is followed by more than 200,000 people on social media. She posts selfies from concerts and her bedroom, while tagging brands such as haircare line Olaplex and lingerie giant Victoria's Secret. Brands have paid about $1,000 a post for her to promote their products on social media -- despite the fact that she is entirely fictional. Aitana is a "virtual influencer" created using artificial intelligence tools, one of the hundreds of digital avatars that have broken into the growing $21 billion content creator economy. Their emergence has led to worry from human influencers their income is being cannibalized and under threat from digital rivals. That concern is shared by people in more established professions that their livelihoods are under threat from generative AI -- technology that can spew out humanlike text, images and code in seconds. But those behind the hyper-realistic AI creations argue they are merely disrupting an overinflated market. "We were taken aback by the skyrocketing rates influencers charge nowadays. That got us thinking, 'What if we just create our own influencer?'" said Diana Nunez, co-founder of the Barcelona-based agency The Clueless, which created Aitana. "The rest is history. We unintentionally created a monster. A beautiful one, though." Over the past few years, there have been high-profile partnerships between luxury brands and virtual influencers, including Kim Kardashian's make-up line KKW Beauty with Noonoouri, and Louis Vuitton with Ayayi. Instagram analysis of an H&M advert featuring virtual influencer Kuki found that it reached 11 times more people and resulted in a 91 per cent decrease in cost per person remembering the advert, compared with a traditional ad. "It is not influencing purchase like a human influencer would, but it is driving awareness, favorability and recall for the brand," said Becky Owen, global chief marketing and innovation officer at Billion Dollar Boy, and former head of Meta's creator innovations team. "Influencers themselves have a lot of negative associations related to being fake or superficial, which makes people feel less concerned about the concept of that being replaced with AI or virtual influencers," said Rebecca McGrath, associate director for media and technology at Mintel. "For a brand, they have total control versus a real person who comes with potential controversy, their own demands, their own opinions," McGrath added.

Chemicals of 'Concern' Found In Philips Breathing Machines

Fri, 12/29/2023 - 9:02pm
In 2021, Philips pulled its popular sleep apnea machines and ventilators off the shelves after discovering that an industrial foam built into the devices to reduce noise could release toxic particles and fumes into the masks worn by patients. "But as Philips publicly pledged to send out replacements, supervisors inside the company's headquarters near Pittsburgh were quietly racing to manage a new crisis that threatened the massive recall and posed risks to patients all over again," reports ProPublica. "Tests by independent laboratories retained by Philips had found that a different foam used by the company -- material fitted inside the millions of replacement machines -- was also emitting dangerous chemicals, including formaldehyde, a known carcinogen." "Though Philips has said the machines are safe, ProPublica and the Pittsburgh Post-Gazette obtained test results and other internal records that reveal for the first time how scientists working for the company grew increasingly alarmed and how infighting broke out as the new threat reached the highest levels of the Pittsburgh operation. The findings also underscore an unchecked pattern of corporate secrecy that began long before Philips decided to use the new foam." From the report: The company had previously failed to disclose complaints about the original foam in its profitable breathing machines, a polyester-based polyurethane material that was found to degrade in heat and humidity. Former patients and others have described hundreds of deaths and thousands of cases of cancer in government reports. After the introduction of the new foam in 2021, this one made of silicone, the company again held back details about the problem from the public even as it sent out replacement machines with the new material to customers around the world. One of the devices was the DreamStation 2, a newly released continuous positive airway pressure, or CPAP, machine promoted as one of the company's primary replacements. Federal regulators were alerted to the concern more than two years ago but said in a news release at the time that the company was carrying out additional tests on the foam and that patients should keep using their replacements until more details were available. The Food and Drug Administration has not provided new information on the test results since then, and it is still unclear whether the material is safe. That leaves millions of people in the United States alone caught in the middle, including those with sleep apnea, which causes breathing to stop and start through the night and can lead to heart attacks, strokes and sudden death. The new foam isn't the only problem: An internal investigation at Philips launched in the months after the recall found that water was condensing in the circuitry of the DreamStation 2, creating a new series of safety risks. "Loss of therapy, thermal events, and shock hazards," the investigation concluded. The FDA issued an alert about overheating last month, warning that the devices could produce "fire, smoke, burns, and other signs of overheating" and advising patients to keep the machines away from carpet, fabric and "other flammable materials." Philips has said that customers could continue using the devices if they followed safety instructions. ...

First EV With Lithium-Free Sodium Battery Hits the Road In January

Fri, 12/29/2023 - 8:25pm
Deliveries of the world's first mass-produced electric vehicle equipped with a sodium-ion battery will begin in January 2024. According to CarNewsChina, they're being produced by JAC Motors, a Volkswagen-backed Chinese automaker, through its new Yiwei EV brand. From the report: The Yiwei EV hatchback will have a cylindrical sodium-ion pack from Beijing-based HiNa Battery and adopt JAC's UE (Unitized Encapsulation) module technology. UE is also known as a honeycomb design because of its appearance. It is another battery structure concept like CATL's CTP (cell-to-pack) or BYD's Blade battery. Yiwei is a new EV brand under Anhui Jianghuai Automobile (JAC), established in 2023. JAC's parent company, Anhui Jianghuai Automobile Group Holdings (JAG), is 50% state-owned, and 50% belongs to Volkswagen Group. The German automotive giant acquired its stake in 2020 in an unprecedented move to invest in China's state-owned car maker. [...] In February 2023, JAC announced they were the first automaker to put the lithium-free sodium-ion battery on an electric vehicle. That EV was a Sehol E10X hatchback, and the Na+ battery had the following specifications: 25 kWh capacity, 120 Wh/kg energy density (single cell 140 Wh/kg), 3C to 4C charging (10% - 80% in 20 minutes), 252 km (157 miles) range for E10X, and HiNa NaCR32140 cell. Sehol was a brand under Volkswagen Anhui JV, which VW transferred to JAC in 2021. When the Yiwei brand was launched in May 2023, JAC announced that it would ditch the Sehol brand, and all vehicles are being rebadged to JAC or Yiwei. The pictures JAC released today tell us that the new sodium-ion-powered EV is the Sehol E10X. JAC hasn't yet confirmed the name of the new car under the Yiwei brand; it could be Yiwei E10X, but we have to wait for JAC's confirmation. JAC recently pushed a lot into sodium-ion batteries R&D. During the Shanghai Auto Show in April 2023, the company showcased its first car under the Yiwei brand called Yiwei 3, which was equipped with a sodium-ion battery. However, the EV launched later in June, only with a classic LFP lithium battery, and promised the Na+ variant would come later. The Yiwei 3 is a compact hatchback that competes with Wuling Bingo, BYD Seagull, or ORA Funky Cat. It has two power train options, both front-wheel drive: 70 kW and 100 kW motor. The maximum cruising range is 505 km CLTC with a 51.5 kWh battery.

UK Startup Develops Low Carbon Jet Fuel Made From Human Waste

Fri, 12/29/2023 - 7:45pm
Chemists at a lab in Gloucertershire have developed a low carbon jet fuel made entirely from human sewage. James Hygate, Firefly Green Fuels CEO, said: "We wanted to find a really low-value feedstock that was highly abundant. And of course poo is abundant." The BBC reports: Independent tests by international aviation regulators found it was nearly identical to standard fossil jet fuel. Firefly's team worked with Cranfield University to examine the fuel's life cycle carbon impact. It concluded that Firefly's fuel has a 90% lower carbon footprint than standard jet fuel. Mr Hygate, who has been developing low-carbon fuels in Gloucestershire for 20 years, said although the new fuel was chemically just like fossil-based kerosene, it "has no fossil carbon, it's a fossil-free fuel." "Of course energy would be used (in production), but when looking at the fuel's life cycle, a 90% saving is mind-blowing, so yes, we have to use energy but it is much lower compared to the production of fossil fuels," he added. [...] First, they create what they call "bio-crude." It looks like oil: thick, black, gloopy. Most importantly, it behaves like crude oil chemically. Dr Sergio Lima, who is also research director at Firefly Green Fuels, said: "What we are producing here is a fuel which is net zero." [...] The bio-kerosene is now being tested independently at the DLR Institute of Combustion Technology at the German Aerospace Center, working with Washington State University. Further future testing will also be carried out by the UK SAF (Sustainable Aviation Fuels) clearing House, based at University of Sheffield. First results have confirmed the fuel has near-identical chemical composition to A1 fossil jet fuel. The UK Department of Transport has awarded the team a 2 million pound research grant. So they can make a test tube of kerosene in the lab. That is a long way from replacing kerosene in the world's airports. Mr Hygate has done his maths. Each human, he calculates, makes enough sewage in a year to produce 4-5 liters of bio jet fuel. To fly a passenger jet from London to New York would need the annual sewage of 10,000 people. And another 10,000 to come back. Put another way, the UK's total sewage supply would meet about 5% of the country's total aviation fuel demand. It may sound small, but he insists: "That's pretty exciting." "There's a 10% sustainable aviation fuel requirement, that's a legal mandate. And we could meet half of that with poo."

Scientists Still Shoot For the Moon With Patent-Free Covid Drug

Fri, 12/29/2023 - 7:02pm
An anonymous reader quotes a report from Bloomberg, written by Naomi Kresge: In the early days of the Covid-19 pandemic, hundreds of scientists from all over the world banded together in an open-source effort to develop an antiviral that would be available for all. They could never have anticipated the many roadblocks they would face along the way, including the Russian invasion of Ukraine, which made refugees out of a group of Kyiv chemists who were doing important work for the project. The group, which called itself Covid Moonshot, hasn't given up on its effort to introduce a more affordable, patent-free treatment for the virus. Their open-source Covid antiviral, now funded by Wellcome, is on track to be ready for human testing within the next year and a half, according to Annette von Delft, a University of Oxford scientist and one of the Moonshot group's leaders. More early discovery work on a range of potential inhibitors for other viruses is also still going on and being funded by a US government grant. "It's a bit like a proof of concept," von Delft says, for bringing a patent-free experimental drug into the clinic, a model that could be repurposed as a tool to fight neglected tropical diseases or antimicrobial resistance, or prepare for future pandemics. "Can we come up with a strategic model that can help those kinds of compounds with less of a business case along?" Of course, there was definitely a business case for a Covid antiviral, and some of the biggest drugmakers rushed to develop them. In 2022, Pfizer Inc.'s Paxlovid was one of the world's best-selling medicines with $18.9 billion in revenue. Demand has since cratered for the pill, which needs to be given shortly after infection and can't be taken alongside a number of other commonly prescribed medicines. Analysts expect the Paxlovid revenue to plunge just shy of $1 billion this year. However, there is still a need for a better Covid antiviral, particularly in countries where access to the Pfizer pill is limited, according to von Delft. Covid cases have surged again this holiday season, with the rise of a new variant called JN.1 reminding us that the virus is still changing to evade the immunity we've built up so far. Just before Christmas, UK authorities said about one in every 24 people in England and Scotland had the disease. An accessible antiviral could help people return to work more quickly, and it could also be tested as a potential treatment for long Covid. "We know from experience in viral disease that there will be resistance variants evolving over time," von Delft said. "We'll need more than one."

Disney, Warner, Comcast, and Paramount Are Contemplating Cuts, Possible Mergers

Fri, 12/29/2023 - 5:40pm
After losing more than $5 billion in the past year, the world's largest traditional entertainment companies -- Disney, Warner Bros Discovery, Comcast and Paramount -- are contemplating cuts and possible mergers to ultimately help better compete with Netflix. The Financial Times reports (via Ars Technica): Shari Redstone, Paramount's billionaire controlling shareholder, has effectively put the company on the block in recent weeks. She has held talks about selling the Hollywood studio to Skydance, the production company behind Top Gun: Maverick, people familiar with the matter say. Paramount chief executive Bob Bakish also discussed a possible combination over lunch with Warner CEO David Zaslav in mid-December. In both cases the discussions were said to be at an early stage and people familiar with the talks cautioned that a deal might not materialize. Beyond their streaming losses, the traditional media groups are facing a weak advertising market, declining television revenues and higher production costs following the Hollywood strikes. Rich Greenfield, an analyst at LightShed Partners, said Paramount's deal discussions were a reflection of the "complete and utter panic" in the industry. "TV advertising is falling far short, cord-cutting is continuing to accelerate, sports costs are going up and the movie business is not performing," he said. "Everything is going wrong that can go wrong. The only thing [the companies] know how to do to survive is try to merge and cut costs." But as the traditional media owners struggle, Netflix, the tech group that pioneered the streaming model over a decade ago, has emerged as the winner of the battle to reshape video distribution. "For much of the past four years, the entertainment industry spent money like drunken sailors to fight the first salvos of the streaming wars," analyst Michael Nathanson wrote in November. "Now, we are finally starting to feel the hangover and the weight of the unpaid bar bill." For companies that have been trying to compete with Netflix, Nathanson added, "the shakeout has begun." After a bumpy 2022, Netflix has set itself apart from rivals -- most notably by being profitable. Earnings for its most recent quarter soared past Wall Street's expectations as it added 9 million new subscribers -- the strongest rise since early 2020, when Covid-19 lockdowns led to a jump. "Netflix has pulled away," says John Martin, co-founder of Pugilist Capital and former chief executive of Turner Broadcasting. For its rivals, he said, the question is "how do you create a viable streaming service with a viable business model? Because they're not working." The leading streaming services aggressively raised prices in 2023. Now, analysts, investors and executives predict that consolidation could be ahead next year as some of the smaller services combine or bow out of the streaming wars.

Social Media Companies Made $11 Billion In US Ad Revenue From Minors, Study Finds

Fri, 12/29/2023 - 5:00pm
An anonymous reader quotes a report from the Associated Press: Social media companies collectively made over $11 billion in U.S. advertising revenue from minors last year, according to a study from the Harvard T.H. Chan School of Public Health published on Wednesday. The researchers say the findings show a need for government regulation of social media since the companies that stand to make money from children who use their platforms have failed to meaningfully self-regulate. They note such regulations, as well as greater transparency from tech companies, could help alleviate harms to youth mental health and curtail potentially harmful advertising practices that target children and adolescents. To come up with the revenue figure, the researchers estimated the number of users under 18 on Facebook, Instagram, Snapchat, TikTok, X (formerly Twitter) and YouTube in 2022 based on population data from the U.S. Census and survey data from Common Sense Media and Pew Research. They then used data from research firm eMarketer, now called Insider Intelligence, and Qustodio, a parental control app, to estimate each platform's U.S. ad revenue in 2022 and the time children spent per day on each platform. After that, the researchers said they built a simulation model using the data to estimate how much ad revenue the platforms earned from minors in the U.S. The platforms themselves don't make public how much money they earn from minors. [...] According to the Harvard study, YouTube derived the greatest ad revenue from users 12 and under ($959.1 million), followed by Instagram ($801.1 million) and Facebook ($137.2 million). Instagram, meanwhile, derived the greatest ad revenue from users aged 13-17 ($4 billion), followed by TikTok ($2 billion) and YouTube ($1.2 billion). The researchers also estimate that Snapchat derived the greatest share of its overall 2022 ad revenue from users under 18 (41%), followed by TikTok (35%), YouTube (27%), and Instagram (16%). "As concerns about youth mental health grow, more and more policymakers are trying to introduce legislation to curtail social media platform practices that may drive depression, anxiety, and disordered eating in young people," said senior author Bryn Austin, professor in the Department of Social and Behavioral Sciences. "Although social media platforms may claim that they can self-regulate their practices to reduce the harms to young people, they have yet to do so, and our study suggests they have overwhelming financial incentives to continue to delay taking meaningful steps to protect children."

Microsoft Disables MSIX Protocol Handler Abused in Malware Attacks

Fri, 12/29/2023 - 4:20pm
Microsoft has again disabled the MSIX ms-appinstaller protocol handler after multiple financially motivated threat groups abused it to infect Windows users with malware. From a report: The attackers exploited the CVE-2021-43890 Windows AppX Installer spoofing vulnerability to circumvent security measures that would otherwise protect Windows users from malware, such as the Defender SmartScreen anti-phishing and anti-malware component and built-in browser alerts cautioning users against executable file downloads. Microsoft says the threat actors use both malicious advertisements for popular software and Microsoft Teams phishing messages to push signed malicious MSIX application packages. "Since mid-November 2023, Microsoft Threat Intelligence has observed threat actors, including financially motivated actors like Storm-0569, Storm-1113, Sangria Tempest, and Storm-1674, utilizing the ms-appinstaller URI scheme (App Installer) to distribute malware," the company said.

Wi-Fi 7 Signals the Industry's New Priority: Stability

Fri, 12/29/2023 - 3:40pm
Multi-link operations and the 6-GHz band promise more reliability than before. From a report: The key to a future Wi-Fi you can depend on is something called multi-link operations (MLO). "It is the marquee feature of Wi-Fi 7," says Kevin Robinson, president and CEO of the Wi-Fi Alliance. MLO comes in two flavors. The first -- and simpler -- of the two is a version that allows Wi-Fi devices to spread a stream of data across multiple channels in a single frequency band. The technique makes the collective Wi-Fi signal more resilient to interference at a specific frequency. Where MLO really makes Wi-Fi 7 stand apart from previous generations, however, is a version that allows devices to spread a data stream across multiple frequency bands. For context, Wi-Fi utilizes three bands-2.5 gigahertz, 5 GHz, and as of 2020, 6 GHz. Whether MLO spreads signals across multiple channels in the same frequency band or channels across two or three bands, the goals are the same: dependability and reduced latency. Devices will be able to split up a stream of data and send portions across different channels at the same time -- which cuts down on the overall transmission time -- or beam copies of the data across diverse channels, in case one channel is noisy or otherwise impaired. MLO is hardly the only feature new to Wi-Fi 7, even if industry experts agree it's the most notable. Wi-Fi 7 will also see channel size increase from 160 megahertz to a new maximum of 320 MHz. Bigger channels means more throughput capacity, which means more data in the same amount of time. That said, 320-MHz channels won't be universally available. Wi-Fi uses unlicensed spectrum -- and in some regions, contiguous 320-MHz chunks of unlicensed spectrum don't exist because of other spectrum allocations. In cases where full channels aren't possible, Wi-Fi 7 includes another feature, called puncturing. "In the past, let's say you're looking for 320 MHz somewhere, but right within, there's a 20-MHz interferer. You would need to look at going to either side of that," says Andy Davidson, senior director of technology planning at Qualcomm. Before Wi-Fi 7, you'd functionally be stuck with about a 160-MHz channel either above or below that interference.

Michael Cohen Used AI To Feed Lawyer Bogus Cases

Fri, 12/29/2023 - 3:00pm
Michael D. Cohen, the onetime fixer for former President Donald J. Trump, said in newly unsealed court papers that he had mistakenly given his lawyer bogus legal citations after the AI program Google Bard cooked them up for him. From a report: The fictitious citations were then used in a motion provided to a Manhattan federal judge. Mr. Cohen, who pleaded guilty in 2018 to campaign finance violations and served time in prison, had asked for an early end to court supervision of his case now that he was out of prison and had complied with the conditions of his release. In a sworn declaration made public on Friday, Mr. Cohen explained that he had not kept up with "emerging trends (and related risks) in legal technology and did not realize that Google Bard was a generative text service that, like ChatGPT, could show citations and descriptions that looked real but actually were not." He also said he did not realize that the lawyer filing the motion on his behalf, David M. Schwartz, "would drop the cases into his submission wholesale without even confirming that they existed." The revelation could have serious implications for the Manhattan criminal case against Mr. Trump, in which Mr. Cohen is expected to serve as the star witness. The former president's lawyers have long attacked Mr. Cohen as a serial fabulist; now, they will have a brand-new example.

LG is Bringing a 4K Projector With a Weird Handle To CES 2024

Fri, 12/29/2023 - 2:14pm
LG just announced its latest 4K projector, the CineBeam Qube. It'll officially unveil the projector at CES 2024 in early January, but the company's giving curious consumers an early look. From a report: The CineBeam Qube has plenty of high-tech bells and whistles, but with a stylish design that LG calls "minimalist." There's also a handle that resembles a crank. Yeah this thing has an actual handle. The CineBeam Qube is built for portability. It's lightweight, at around three pounds, and the square form factor makes it easy to place just about anywhere. The 360-degree rotatable handle also helps with placement. LG's calling it "one of the smallest projectors available." Of course, the most important part of any projector is, well, the projection. The Qube projects 4K UHD (3,840 x 2,160) resolution images that measure up to 120 inches. There's an RGB laser light source, a 450,000:1 contrast ratio and 154 percent coverage of the DCI-P3 color gamut. With these specs, that episode of Reacher will really pop. Speaking of streaming content, the projector runs on LG webOS 6.0 and offers access to all of the big streaming services, including Prime Video, Disney+, Netflix and YouTube.

Toyota-owned Automaker Halts Japan Production After Admitting It Tampered With Safety Tests for 30 Years

Fri, 12/29/2023 - 1:00pm
Daihatsu, the Japanese automaker owned by Toyota, has halted domestic production after admitting it forged the results of safety tests for its vehicles for more than 30 years. From a report: The brand, best known for manufacturing small passenger cars, has stopped output at all four of its Japanese factories as of Tuesday, including one at its headquarters in Osaka, a spokesperson told CNN. The shutdown will last through at least the end of January, affecting roughly 9,000 employees who work in domestic production, according to the representative. The move comes as Daihatsu grapples with a deepening safety scandal that Toyota says "has shaken the very foundations of the company." Last week, Daihatsu announced an independent third-party committee had found evidence of tampering with safety tests on as many as 64 vehicle models, including those sold under the Toyota brand. As a result, Daihatsu said it would temporarily suspend all domestic and international vehicle shipments and consult with authorities on how to move forward. The scandal is another blow to the automaker, which had admitted in April to violating standards on crash tests on more than 88,000 cars, mostly sold under the Toyota brand in countries such as Malaysia and Thailand. In that case, "the inside lining of the front seat door was improperly modified" for some checks, while Daihatsu did not comply with regulatory requirements for certain side collision tests, it said in a statement at the time.
