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.

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.

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. ...

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.
