U.S. traffic safety regulators have launched an inquiry into Elon Musk’s self-driving “robotaxi” trials in Texas following viral videos showing Teslas braking abruptly, veering down the wrong side of the road, and crossing intersections from incorrect lanes. The National Highway Traffic Safety Administration (NHTSA) confirmed on Tuesday that it has contacted Tesla for more details about the incidents. Although other clips show the robotaxis functioning smoothly, any significant findings from the inquiry could raise concerns over Musk’s repeated assurances about the technology's safety and his ambitious vision of an autonomous future dominated by Tesla vehicles — potentially without steering wheels or drivers. “NHTSA is aware of the referenced incidents and is in contact with the manufacturer to gather additional information,” the agency said in a statement. Passengers testing Tesla robotaxis on Austin roads have generally reported positive experiences, and Tesla’s stock price rose by 8% on Monday. However, news of the federal inquiry caused the stock to fall more than 2% on Tuesday. Tesla has yet to comment publicly. Google may be forced to link to rival search platforms in the UK Dan Ives, a bullish Tesla analyst at Wedbush Securities who experienced a flawless ride during Sunday’s launch of the test program, dismissed the concerning footage circulating on platforms like X and YouTube. “Any issues they encounter will be fixed,” Ives said, calling the test program a “huge success” over the past three days “despite the skeptics.” One such skeptic, vehicle technology expert Sam Abuelsamid of Telemetry Insight, argued the footage was worrying enough to pause public testing altogether. “The system has always had highly erratic performance, working really well a lot of the time but frequently making random and inconsistent but dangerous errors,” Abuelsamid wrote in a message. “This is not a system that should be carrying members of the public or being tested on public roads without trained test drivers behind the wheel.” One widely shared video shows a Tesla entering a left-turn-only lane, but instead of turning, it drives straight through the intersection and into an oncoming lane. The vehicle then swerves several times, with the steering wheel jerking back and forth, before stabilizing. The car proceeds down the wrong side of the road for around 10 seconds. Luckily, no oncoming vehicles were present. The passenger who filmed the incident, money manager Rob Maurer, downplayed the situation. “There are no vehicles anywhere in sight, so this wasn’t a safety issue,” Maurer said in his video commentary. “I didn’t feel uncomfortable in the situation.” Another video shows a Tesla braking suddenly in the middle of the road, possibly reacting to the flashing lights of parked police cars, though the officers appeared to be handling a separate matter nearby. NHTSA has been monitoring Tesla’s autonomous technology closely. The agency launched an investigation last year into how Teslas with Musk’s so-called Full Self-Driving system performed in low-visibility conditions, following several crashes — one of them fatal. Tesla had to recall 2.4 million vehicles at the time. Musk insists his Full Self-Driving Teslas are safer than human drivers, and he claims the upgraded robotaxi system will be so reliable that hundreds of thousands will be deployed by the end of next year. OpenAI pulls Jony Ive partnership details after court ruling in trademark dispute Despite the Austin trials, Musk faces stiff competition. Rivals such as Amazon-owned Zoox and Waymo — the current leader in self-driving taxis — have already launched services in multiple cities. Waymo recently announced it had completed its 10 millionth paid ride. Musk is under pressure to deliver a robotaxi breakthrough. His recent role in the Trump administration as a cost-cutting czar has alienated Tesla’s core buyer base, traditionally made up of liberal, environmentally conscious Americans, contributing to declining sales. European markets have also cooled after Musk publicly supported far-right politicians in Britain and Germany earlier this year. Source: Agency    

Google may soon face new requirements in the UK aimed at providing consumers with more choice over which online search services they use, according to the country’s competition watchdog. The UK’s Competition and Markets Authority (CMA) is investigating the tech giant under a new law that allows the regulator to demand changes if it finds that a company holds too much power in a particular market. Google currently dominates the UK search market, accounting for over 90% of searches, with approximately 200,000 businesses using its search advertising services to reach customers, as reported by the BBC. Alphabet, Google's parent company, has criticized the CMA's proposed changes, calling them "broad and unfocused." However, the company has said it will "work constructively" with the regulator moving forward. The CMA, which is not accusing Google of anti-competitive behavior at this stage, has outlined a "roadmap" for potential changes to the company’s operations. These changes could include requiring "choice" screens for users to access different search providers and offering more transparency and control for publishers whose content appears in search results. A final decision is expected in October. According to the CMA, the average person in the UK conducts between five and ten searches per day, and businesses spend an average of £33,000 annually on Google advertisements. The watchdog believes that, if competition were functioning properly, this figure could be lower. "Google search has delivered tremendous benefits but our investigation so far suggests there are ways to make these markets more open, competitive and innovative," said CMA Chief Executive Sarah Cardell. She added that the proposed changes would give UK businesses and consumers more choice and control over how they interact with Google’s search services. However, Google expressed concerns over the potential outcomes of the investigation. A company spokesperson said that while the CMA has reiterated that "strategic market status" does not equate to accusations of anti-competitive behavior, the investigation and proposed changes "could have significant implications for businesses and consumers in the UK." Google faces major setback in appeal against EU antitrust fine over Android They also cautioned that the UK has historically benefited from early access to Google innovations, but this could change as a result of what they described as "punitive regulations." Concerns from Businesses and Publishers The CMA’s investigation, which was launched in January, aims to ensure fair competition in online search. It has heard from 47 organizations, including airlines, adult online retailers, and media publishers, about how Google's search practices help or hinder their businesses. EasyJet, for example, noted that changes to the search engine resulting from the European Union’s Digital Markets Act had diverted more customers to online travel agencies, which misrepresented the airline’s services and prices. In response, Google stated that increasing the visibility of rival search engines and comparison sites was part of the required changes under the EU law. However, the company claimed this move had hurt airlines and hotel operators by reducing direct traffic to their websites. Meanwhile, LoveHoney and Ann Summers, which sell sex toys, lingerie, and sexual wellness products, raised concerns about Google’s SafeSearch feature, which censors explicit results and has affected the "discoverability" of their sites. Trade association UK Hospitality also warned that the UK should be cautious about adopting similar search requirements to those in the EU, fearing they could create "unintended consequences" for both businesses and consumers. Implications for Artificial Intelligence Sebastian Cuttill, of the News Media Association, highlighted that the CMA's intervention could have significant implications not just for traditional search engines but also for AI-powered alternatives, such as Google's own AI Overviews. He argued that increasing transparency over how news content is used by tech firms to develop AI tools would be "massive" for publishers. News organizations, including the BBC, have expressed concerns about the use of their content to train AI systems without consent or compensation. "This measure would pursue the statutory objectives of fair dealing and trust and transparency," Cuttill said. Global Scrutiny Google’s search operations have come under increased scrutiny by regulators in other countries as well. In August, a US judge ruled that the company had operated an illegal search monopoly. Additionally, the European Union has imposed multiple enforcement actions, including a €2.4 billion (£2 billion) fine for allegedly "self-preferencing" its Shopping comparison service, a penalty that was upheld by the bloc’s top court last year.

A promising collaboration between OpenAI CEO Sam Altman and renowned iPhone designer Jony Ive to create a new AI hardware product has encountered a legal obstacle after a federal judge ordered a temporary halt to the marketing of the venture. Last month, OpenAI announced the acquisition of io Products, a product and engineering firm co-founded by Ive, in a deal reportedly worth nearly $6.5 billion. However, the project quickly ran into legal trouble when a startup named IYO, which is also working on AI hardware, filed a trademark infringement complaint. The startup claims its product was pitched to Altman’s personal investment firm and Ive's design company in 2022 and alleges that the new venture's name is confusingly similar to its own. Tesla begins robotaxi test run in Austin U.S. District Judge Trina Thompson ruled on Friday that IYO has a sufficiently strong trademark infringement claim to move forward with legal proceedings, scheduling a hearing for October. Until then, Altman, Ive, and OpenAI are barred from “using the IYO mark, and any mark confusingly similar thereto, including the IO mark, in connection with the marketing or sale of related products.” In response to the ruling, OpenAI removed all references to the new venture from its website, including the original May 21 announcement. The replaced webpage now displays a message stating the content is "temporarily down due to a court order" and adds, "We don’t agree with the complaint and are reviewing our options." IYO CEO Jason Rugolo welcomed the court's decision, issuing a statement on Monday asserting that the company will firmly defend its brand and technology. "IYO will not roll over and let Sam and Jony trample on our rights, no matter how rich and famous they are," Rugolo said.

A malfunction in a laser navigation tool led to the crash of a Japanese company’s lunar lander earlier this month, officials confirmed on Tuesday. Tokyo-based ispace revealed that its lander, named Resilience, failed to make a safe touchdown on the moon’s surface — marking the company’s second lunar crash in as many years. The mission aimed to land near the moon’s far northern region known as Mare Frigoris, or the Sea of Cold. NASA’s Lunar Reconnaissance Orbiter later captured images of the crash site, showing debris from Resilience and its mini rover. According to ispace, the laser range finder responsible for measuring the lander's altitude did not activate promptly, resulting in a failure to calculate the distance to the surface. As a result, Resilience was descending at roughly 138 feet (42 meters) per second when communication was lost. The spacecraft crashed just five seconds later. The company's first lunar mission also ended in disaster in 2023 due to faulty software, with both incidents occurring during the critical final descent phase. Tesla begins robotaxi test run in Austin Out of seven recent private-sector attempts to land on the moon, only one succeeded — Firefly Aerospace's Blue Ghost lander, which touched down in March. Interestingly, Blue Ghost had shared the same SpaceX launch from Florida as Resilience back in January. So far, successful moon landings have been achieved by five nations: the United States, Soviet Union, China, India, and Japan. Among them, only the U.S. has sent astronauts to the lunar surface, during NASA's historic Apollo missions over 50 years ago. Despite consecutive failures, ispace remains committed to lunar exploration. The company is preparing for a third landing attempt in 2027 with support from NASA, along with a fourth mission. Additional tests and technical upgrades are expected to raise project costs by approximately 1.5 billion yen (over $10 million), company officials said. Samsung electronics eyes turnaround in HBM segment amid AI surge CEO and founder Takeshi Hakamada emphasized that ispace remains undeterred by recent setbacks and is determined to restore customer confidence. Independent experts will assist with the crash investigation, and the company plans to strengthen its technical cooperation with the Japanese Space Agency. “We are determined to move forward with our future missions,” Hakamada said in Japanese.

After years of ambitious promises and delays, Elon Musk’s long-touted vision of Tesla “robotaxis” is finally hitting the road — albeit modestly — with a small pilot program launched in Austin, Texas, on Sunday. Tesla began testing 10 to 12 self-driving taxis in a limited, geofenced area of Austin, with each ride costing a flat fee of \$4.20. The vehicles are being remotely monitored and have a person in the passenger seat to intervene if needed, as reported by AP.  Musk took to X to share the news, writing, “The @Tesla\_AI robotaxi launch begins in Austin this afternoon with customers paying a \$4.20 flat fee!” The test run marks a significant moment for Tesla, especially after repeated delays since Musk first promised autonomous taxis back in 2019. At the time, he said they would be operational “next year,” a promise he repeated annually without fulfillment. Most recently, in early 2023, Musk claimed Tesla would have “over a million robotaxis” on the road by 2024. While only a dozen vehicles are active now, Musk has vowed rapid expansion of the service, predicting “hundreds of thousands if not a million vehicles next year.” However, industry analysts remain skeptical. “How quickly can he expand the fleet?” asked Garrett Nelson, an analyst at CFRA. “We're talking maybe a dozen vehicles initially. It's very small." Tesla faces growing pressure from several fronts. Political backlash and boycotts linked to Musk’s statements have contributed to plunging sales. Competitors, including Waymo — which just celebrated its 10 millionth paid ride — have pulled ahead with more mature self-driving technology. Waymo uses a sensor suite combining cameras, radar, and lidar, in contrast to Tesla’s camera-only system. Despite recent turbulence, including a \$150 billion stock decline after Musk’s public clash with President Biden, Tesla’s stock has shown resilience, closing Friday at \$322, up from about \$18 a decade ago. Critics have long challenged Tesla’s “Full Self-Driving” system, arguing it’s misleadingly named and not truly autonomous. Federal safety regulators and the Department of Justice have investigated FSD following accidents and lawsuits, though some legal challenges have been dismissed. In one such case, a judge ruled plaintiffs failed to prove Musk “knowingly” made false claims. Space station leak concerns can delay astronaut visit from India, Poland, Hungary Nonetheless, Musk insists that the improved FSD will power Tesla’s robotaxis safely and allow for swift nationwide rollout. His strategy includes transforming existing Teslas on the road into robotaxis via an over-the-air software update. Owners would be able to earn money by adding their vehicles to the fleet while they’re at work or away, a model Musk compared to Airbnb. “Instead of having your car sit in the parking lot, your car could be earning money,” Musk said earlier this year. “You will be able to add or subtract your car to the fleet.” Musk also maintains that Tesla’s reliance on cameras rather than expensive sensors gives the company an edge in scaling operations quickly. “Tesla will have, I don’t know, 99% market share or something ridiculous,” he said during a recent investor call. Dan Ives of Wedbush Securities remains optimistic: “This time Musk may actually pull it off because of Tesla's ability to scale up quickly.” And while analysts like Goldstein remain cautious, they admit Musk has defied expectations before. “Maybe his timelines aren’t realistic,” Goldstein said, “but he can develop futuristic technology products.”

Samsung Electronics Company is exploring strategies to reclaim its leadership in the high bandwidth memory (HBM) market, following a recent decline in its position, according to sources familiar with the matter. The efforts were discussed during the company’s biannual executive-level strategy meetings, held over three days. Led by division heads, the sessions reviewed regional and business-specific challenges, sales strategies, and performance goals for the latter half of the year. Samsung sees revenue boost from smartphone sales despite chip slump A key focus during Wednesday’s meeting—hosted by the semiconductor division—was HBM sales strategies and production schedules, amid soaring global demand fueled by the recent boom in generative artificial intelligence (AI), Yonhap reported. Samsung’s HBM chips have reportedly failed to pass quality tests by Nvidia Corp., a critical player in the AI hardware sector. This shortfall has prevented Samsung from entering the global HBM supply chain, which is currently led by Nvidia, SK hynix Inc., and Taiwan Semiconductor Manufacturing Co. (TSMC). Consequently, Samsung was overtaken by rival SK hynix in global DRAM market share during the first quarter of 2024. According to data from global market research firm Omdia, SK hynix’s market share rose to 36.9 percent, while Samsung’s dropped to 34.4 percent. In response, Samsung is reviewing its plans to begin mass production of its next-generation HBM4 chips in the second half of the year—a move the company hopes will be a game-changer in regaining its competitive edge.

Pavel Durov, the founder and CEO of instant messaging app Telegram, plans to leave his fortune to the more than 100 children he has fathered. The Russian-born tech tycoon has revealed that his estate will be split between his six children from relationships and the scores of others whom he fathered through sperm donation. In a wide-ranging interview published Thursday in French political magazine Le Point, 40-year-old Durov revealed that he does not differentiate between his legal children with three different women and those conceived with the sperm he donated. “They are all my children and will all have the same rights! I don’t want them to tear each other apart after my death,” he said, after revealing that he recently wrote his will.   Durov revealed the number of children he has fathered on his social media last year. He said a doctor told him that it was his “civic duty” to donate his “high quality donor material,” which he did over the course of 15 years. According to Bloomberg, Durov is worth an estimated $13.9 billion, but he dismissed such estimates as “theoretical,” telling Le Point: “Since I’m not selling Telegram, it doesn’t matter. I don’t have this money in a bank account. My liquid assets are much lower – and they don’t come from Telegram: they come from my investment in bitcoin in 2013.” Regardless, his children will have a long wait for their inheritance. He said: “I decided that my children would not have access to my fortune until a period of 30 years has elapsed, starting from today. I want them to live like normal people, to build themselves up alone, to learn to trust themselves, to be able to create, not to be dependent on a bank account. I want to specify that I make no difference between my children: there are those who were conceived naturally and those who come from my sperm donations.” Cybernews researchers report billions of login credentials leaked online When asked why he has written his will now, Durov, who lives in Dubai, said: “My work involves risks – defending freedoms earns you many enemies, including within powerful states. I want to protect my children, but also the company I created, Telegram. I want Telegram to forever remain faithful to the values I defend.” Telegram, which has more than a billion monthly users, is known for its high-level encryption and limited oversight on what its users post. Last year, Durov was arrested in Paris on charges relating to a host of crimes, including allegations that his platform was complicit in aiding money launderers, drug traffickers and people spreading child pornography. Google faces major setback in appeal against EU antitrust fine over Android Durov, who is Telegram’s sole shareholder, has denied the charges, which he described as “absurd.” “Just because criminals use our messaging service among many others doesn’t make those who run it criminals,” he told the French magazine.

Researchers at cybersecurity outlet Cybernews say that billions of login credentials have been leaked and compiled into datasets online, giving criminals “unprecedented access” to accounts consumers use each day. According to a report published this week, Cybernews researchers have recently discovered 30 exposed datasets that each contain a vast amount of login information — amounting to a total of 16 billion compromised credentials. That includes user passwords for a range of popular platforms including Google, Facebook and Apple. Sixteen billion is roughly double the amount of people on Earth today, signaling that impacted consumers may have had credentials for more than one account leaked. Cybernews notes that there are most certainly duplicates in the data and so “it's impossible to tell how many people or accounts were actually exposed.” It's also important to note that the leaked login information doesn't span from a single source, such as one breach targeting a company. Instead, it appears that the data was stolen through multiple events over time, and then compiled and briefly exposed publicly, which is when Cybernews reports that its researchers discovered it. Various infostealers are most likely the culprit, Cybernews noted. Infostealers are a form of malicious software that breaches a victim's device or systems to take sensitive information. Many questions remain about these leaked credentials, including whose hands the login credentials are in now. But, as data breaches become more and more common in today's world, experts continue to stress the importance of maintaining key “cyber hygiene.” If you're worried about your account data potentially being exposed in a recent breach, the first thing you can do is change your password — and avoid using the same or similar login credentials on multiple sites. If you find it too hard to memorize all your different passwords, consider a password manager or passkey. And also add multifactor authentication, which can serve as a second layer of verification through your phone, email or USB authenticator key.

A Chinese research team has developed a new remote-sensing satellite model, which has for the first time achieved the high-precision, dynamic calculation of CO2 emissions from large coal-fired power plants, providing a new solution for global carbon emissions monitoring. Coal-fired power plants account for nearly 50 per cent of the total carbon emissions from fossil fuel combustion globally. They are a crucial component in the estimation of carbon emissions resulting from human activity. The precise, scientific calculation of carbon emissions from coal-fired power plants is of significant importance. However, established calculation methods depend heavily on the product of fuel consumption reported by power plants and carbon emissions factors, which makes estimations difficult to compare and verify. Current remote-sensing satellite technology can also result in inversion errors as high as 50 per cent due to background interference and atmospheric instability. SpaceX rocket explodes during test in Texas The research team at the Chinese Academy of Sciences' Aerospace Information Research Institute optimized algorithms and constructed this new model to quantify the CO2 emissions of 14 large coal-fired power plants around the world based on satellite data, significantly improving inversion accuracy. According to the team's recent paper in the Journal of Cleaner Production, the new model provides an objective, effective means for the verification of carbon emissions from key global sources, and offers a scientific basis for carbon-trading auditing and the calibration of emissions reduction policies.
