After Meta CEO Mark Zuckerberg posted a video on his Facebook and Instagram accounts of his free time during the Independence Day holiday on the X platform, Musk said, "I prefer to work." Zuckerberg posted a video of himself surfing on a hydrofoil in a tuxedo, waving an American flag and drinking a beer, and wrote: "Happy birthday America." The video quickly went viral, and after greg shared it on the X platform, Musk replied: "I hope he continues to have fun on the yacht." I prefer to work." Musk, a workaholic, attended the 29th annual Barron Investment Conference in November 2022, where he said: "My workload went from 78 hours a week to 120 hours a week..." In 2018, he slept on the floor of the Gigafactory in Fremont in an effort to ramp up production of the Tesla Model 3.

In a groundbreaking discovery, researchers from the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences have found a desert moss species, known as Syntrichia caninervis, that has the potential to survive in the extreme conditions on Mars. The Global Times learned from the institute that during the third Xinjiang scientific expedition, the research team focused on studying the desert moss and found that it not only challenges people's understanding of the tolerance of organisms in extreme environments, but also demonstrates the ability to survive and regenerate under simulated Martian conditions. Supported by the Xinjiang scientific expedition project, researchers Li Xiaoshuang, Zhang Daoyuan and Zhang Yuanming from the Xinjiang Institute of Ecology and Geography and Kuang Tingyun, an academician from the Chinese Academy of Sciences, concentrated on studying the "pioneer species" Syntrichia caninervis in an extreme desert environment, according to the institute in an article it sent to the Global Times on Sunday. Through scientific experiments, the researchers systematically proved that the moss can tolerate over 98 percent cell dehydration, survive at temperatures as low as -196 C without dying, withstand over 5000Gy of gamma radiation without perishing, and quickly recover, turn green, and resume growth, showcasing extraordinary resilience. These findings push the boundaries of human knowledge on the tolerance of organisms in extreme environments. Furthermore, the research revealed that under simulated Martian conditions with multiple adversities, Syntrichia caninervis can still survive and regenerate when returned to suitable conditions. This marks the first report of higher plants surviving under simulated Martian conditions. The research team also identified unique characteristics of Syntrichia caninervis. Its overlapping leaves reduce water evaporation, while the white tips of the leaves reflect intense sunlight. Additionally, the innovative "top-down" water absorption mode of the white tips efficiently collects and transports water from the atmosphere. Moreover, the moss can enter a selective metabolic dormancy state in adverse environments and rapidly provide the energy needed for recovery when its surrounding environment improves. Based on the extreme environmental tolerance of Syntrichia caninervis, the research team plans to conduct experiments on spacecraft to monitor the survival response and adaptation capabilities of the species under microgravity and various ionizing radiation adversities. They aim to unravel the physiological and molecular basis of the moss and explore the key life tolerance regulatory mechanisms, laying the foundation for future applications of Syntrichia caninervis in outer space colonization.

Koenigsegg Agera RS Chimera combines technologies from Agera RS, CC850, and Jesko. An Agera RS platform features the engine from the Jesko and the simulated manual gearbox from the CC850. Development took three years, thanks to software and hardware integration challenges. A "chimera," for the uninitiated, is described as a mythical creature whose anatomy comes from multiple animals, creating a hybrid of two or more creatures' best bits. It's also the name of the latest one-off creation from Koenigsegg, and it's certainly apt; the Koenigsegg Agera RS Chimera is an amalgam of technologies from the decade-old, record-breaking Agera RS, the fascinatingly innovative CC850, and the awe-inspiring Jesko - which just recently set four new acceleration records. There's also a hint of Regera in here, which had some impressive records of its own. As reported by Mr. JWW, the strictly one-off special edition was commissioned by FIA President Mohammed Ben Sulayem, and both he and one of Koenigsegg's engineers arrived at the same name. Let's take a closer look and see exactly why this is a hybrid, even though it's not electrified. Three Cars In One The Chimera was originally a regular Agera RS and one of several Koenigsegg megacars owned by Ben Sulayem, but he asked Christian and the team to initiate a special project on his behalf. Around the same time, the extraordinary Koenigsegg CC850 was revealed at Monterey Car Week 2022, introducing the innovative Engage Shift System (ESS). This was based on the already astonishingly fast nine-speed Light Speed Transmission, with new actuators and sensors added to enable the simulation of a manual transmission without a physical link between the shifter and the gearbox. Like the rest of the world, the FIA boss was enamored by this novel technology, and as a wealthy 'Egg collector, he asked for it to be put into his special Agera-based project. Christian pondered this and ultimately decided to fulfill the request, in the process turning Ben Sulayem's special edition into something of a development mule for the ESS. But unlike the CC850, the Chimera got the larger turbos of the Jesko, enabling around 1,280 horsepower on regular gas and up to 1,600 hp on E85. That means this is an Agera RS with a CC850 transmission and a Jesko engine. On paper, that sounds simple, but the reality was anything but... Three Shifting Experiences Took Three Years To Combine According to a video from YouTuber and Koenigsegg distributor Mr. JWW, this development process took three years and required the relocation of the battery, new mounts for the powertrain, new harnesses, new software and controllers, and even a new infotainment system. To ensure all the electronics worked seamlessly was a challenge, but then Ben Sulayem asked for another layer of intricacy, requesting that paddle shifters be added, like in the Jesko Absolut and Jesko Attack. In the CC850, you could only switch between the simulated manual mode and fully automatic shifts, but now, the Chimera's development has unlocked manually operable paddles, which have now been added as the only option you can add to a CC850. There was also significant relocation and redesigning of suspension components, with parts from the Jesko and the Regera forming the subframe and elements of the suspension, respectively. A new scoop for the new transmission's cooler was also added, but it looks like it was always planned. Christian von Koenigsegg says this is a true one-off, saying that it would be cheaper and easier to start something all-new from scratch than to mix new and old technologies again, and that it's simply "too much work" to tackle a retrofit project. The Chimera is not completed just yet, as there are still subtle elements to refine, such as the bite point of the clutch pedal, but these minor issues will surely be resolved soon. It's an amazing feat, combining three hypercars in one, and we can't even fathom how Koenigsegg will top this in the future, but we don't doubt that Christian and his team will continue to do just that.

July 9 (Reuters) - Lucid Group (LCID.O), opens new tab will recall about 5,251 of its 2022-2023 Air luxury sedans due to a software error that could cause a loss of power, according to a notice from the U.S. National Highway Traffic Safety Administration published on Tuesday. The regulator added the EV maker will also recall about 7,506 of its 2022-2024 Air luxury sedans due to an issue with a coolant heater that could fail to defrost the windshield. Lucid had released an over-the-air software update in June as a fix for the software error and a separate update to identify a high voltage coolant heater failure and provide a warning to the drivers of the affected vehicles. The company had reported second-quarter deliveries above market expectations on Monday, as price cuts helped boost demand for its luxury electric sedans.

Recently, according to the FT, citing the latest forecast data of the market research institute SemiAnalysis, AI chip giant NVIDIA will ship more than 1 million new NVIDIA H20 acceleration chips to the Chinese market this year, and it is expected that the cost of each chip is between $12,000 and $13,000. This is expected to generate more than $12 billion in revenue for Nvidia. Affected by the United States export control policy, Nvidia's advanced AI chip exports to China have been restricted, H20 is Nvidia based on H100 specifically for the Chinese market to launch the three "castration version" GPU among the strongest performance, but its AI performance is only less than 15% of H100, some performance is even less than the domestic Ascend 910B. When Nvidia launched the new H20 in the spring of this year, there were reports that due to the large castration of H20 performance, coupled with the high price, Chinese customers' interest in buying is insufficient, and they will turn more to choose China's domestic AI chips. Then there are rumors that Nvidia has lowered the price of the H20 in order to improve its competitiveness. However, the latest news shows that due to supply issues caused by the low yield of the Ascend 910B chip, Chinese manufacturers in the absence of supply and other better options, Nvidia H20 has started to attract new purchases from Chinese tech giants such as Baidu, Alibaba, Tencent and Bytedance. Analysts at both Morgan Stanley and SemiAnalysis said the H20 chip is now being shipped in bulk and is popular with Chinese customers, despite its performance degradation compared to chips Nvidia sells in the United States.
