China's Humanoid Robots Race Against Humans
Beijing:
Some of China's best humanoid robots took on the challenge of racing against human marathon runners on Saturday. One fell at the starting line. Another's head fell off and rolled on the ground. And one collapsed and broke into pieces.
In what was billed as the world's first half-marathon for androids, just four out of 21 robotic runners completed the race in Beijing's southern tech hub of E-Town within the allotted four hours. The winner was five-foot-ten Tiangong Ultra, who made it to the finish line in two hours and 40 minutes, far behind the hourlong performance of the human gold medalists. It took more than three hours for the other three bots that managed to complete the 13 mile (20.9 kilometer) course to come in.
The man-versus-machine competition was presented as a showcase for China's ambition in areas from AI to robotics to semiconductors. President Xi Jinping's government has made the development of the key technologies a priority, ratcheting up trade tension with the US.
Yet the result was often comical, with accidents and dropouts throughout the race. While Tiangong paced around five miles per hour and looked like a proper athlete, many of its robotic peers weren't designed to run quickly enough to finish the race within the time.
The Tiangong Ultra model was tailor-made for the race by Beijing-based X-Humanoid, a government-backed research institute that also has funding from Xiaomi Corp. and robotics upstart UBTech Robotics Corp Ltd.

"I'm very happy with the results, and everything met my expectations," X-Humanoid's Chief Technology Officer Tang Jian said in an interview. "This has been an extreme test of the robots' resilience and stability. Our hope is that, whatever tasks robots perform in the future, they will be capable of operating around the clock, 24/7."
Still, it took one fall and three batteries for Tiangong to score the win, with the jersey-sporting machine leading the robot contestants throughout the race. A human instructor - wearing a signaling device on his lower back - ran ahead of the bot for it to mimic his moves. Most of the other androids were controlled with joysticks by human operators running alongside them. Some even had leashes. Two dozen teams crossed the starting line in succession, followed by mini shuttle buses with substitutes and engineers on stand-by.
To qualify for the race, the robots had to have a humanoid appearance and run on two legs. They were allowed to replace batteries mid-race or even have a substitute take over, though with time penalties for each substitute used. Bystanders, including parents with toddlers, cheered them on, and even some of the human contestants paused near the start to take photos of their mechanical counterparts.
The robots varied in appearance, height and weight. One giant contestant resembled Japanese fictional anime bot Gundam, with fans attached around its arms. It lost control and crashed onto the barricade separating the human and robot runners. The only female-looking robot, Huan Huan - equipped with mannequinesque head and Storm Trooper-style armor - collapsed shortly after the start, scattering body armor on the track. Neither recovered to continue the race.
Little Giant, developed by local college students, was the shortest contestant at a mere 75 centimeters (30 inches) high. It paced around 1.4 miles per hour and supported voice control, one of its engineers said in a live broadcast on national television. At one point, the machine paused briefly after smoke spewed out of its head. The team only intended for Little Giant to run the first three miles as it's too slow, the engineer said.
Jiang Zheyuan, 27-year-old founder of Noetix Robotics, stood on a stool and chanted slogans as he watched his N2 robot come second. Despite many sleepless nights, the race paid off for the Tsinghua dropout's startup as it helped clients discover the firm, he told reporters at the finishing line. His firm is slated to deliver 700 robots next month at $6,000 apiece, a below-market rate.

Another Noetix N2 robot, using a different algorithm, was third to cross the finishing line, but was demoted to fourth having used three substitutes and incurring more than an hour penalty. The team grumbled that the rule had been changed to their disadvantage and said they planned to lodge a complaint.
Some of China's most promising robotics firms didn't sign up for the race. Hangzhou-based Unitree put out a statement after its G1 bot fell at the starting line that a client had used the machine without deploying Unitree's algorithms. The company - whose founder was among Xi's guests of honor at a prominent meeting with entrepreneurs in February - is busy prepping for a fighting bout, according to the statement.

Young Workforce is Rapidly Declining For Top Tech Companies: Report
New Delhi: Age is catching up for two of India's leading IT companies – Tata Consultancy Services Ltd (TCS) and Infosys Ltd – as they are witnessing a sharp decline in their young workforce, Mint reported. The shrinking number of employees under 30, as stated in the companies annual reports, have raised concerns over the sustainability of the traditional employee pyramid model. According to the report, at the end of FY25, just 47.7% of TCS employees in India were below 30, down from 59% in FY22, implying that the company had 44,542 fewer young employees than it had three years ago. Meanwhile, at Infosys, only 52% of its 323,578 employees were equal to or under 30 years of age at the end of FY25, down from 60% in FY22 – signalling a net drop of about 17,609 younger employees. According to the daily, one of the reasons could be that automation is eliminating a significant chunk of entry-level jobs, signalling broader shifts in the IT services market. With automation tools on offer, the need for younger employees who typically handled customer support roles has reduced. As a result, young graduates are more drawn to startups, software product makers, or tech centres of global firms like Google and Microsoft. These also allow them better pay, faster growth and more creative work, according to some analysts. Another reason is that the traditional pyramid model may now be dated causing companies to see their margins erode. According to the report, TCS's revenue in FY25 rose only 3.78% to USD 30.18 billion – slowest in four years – while Infosys's revenue growth was also sluggish at 3.85%, touching USD 19.28 billion. Economic uncertainty One of the other major reasons why the growth has noticeably slowed down now is because global clients are cutting back on tech spending due to economic uncertainty. A Mumbai-based analyst told Mint that slow hiring was a result of the sluggish demand for IT services. 'IT services providers hire junior employees, most of whom fall under 30, when there is high demand for tech services. This was the case in FY22 when plenty of freshers were added. Now, because growth has been a little sluggish, hiring has been low, and which is why we see fewer young people.' In FY22, TCS and Infosys had added over 157,000 employees combined whereas in FY25, that number dropped to 12,771. According to the report, this also shows up in campus placement data of engineering colleges as they report lesser offers from the top IT service companies. Final-year students who would typically receive early offers from these firms are now seeking opportunities at software product firms, fintech startups, or hunting for overseas universities instead. Bigger issue abroad The issue of ageing workforce becomes more pressing in key markets abroad as the firms are losing their appeal among young job seekers. In North America, which contributes over half of TCS's revenue, more than 20% of its workforce is over 50 years old, the daily stated. In Europe, nearly 28% of its employees are above 50. On the other hand, Infosys received 4.46 million job applications in FY25—a 24% drop from FY22.

Want even tinier chips? Use a particle accelerator
Semiconductor chips are among the smallest and most detailed objects humans can manufacture. Shrinking the scale and upping the complexity is a fight against the limits of physics, and optical lithography—etching nanometre-scale patterns onto silicon with short-wavelength light—is its most extreme frontier. ASML , a Dutch firm that builds such lithography tools, takes an almost sci-fi approach by blasting molten tin droplets with lasers in a vacuum to produce extreme ultraviolet (EUV) light with a wavelength of just 13.5nm. Now, some researchers hope to generate more powerful EUV beams with a particle accelerator that propels electrons to nearly the speed of light. The need for this radical proposal stems from a fundamental limitation of current EUV sources: they struggle to generate enough power to reliably etch circuits onto silicon. In a lithography tool such as ASML's, the EUV beam bounces off nearly a dozen mirrors before it hits the silicon. EUV light is so easily absorbed, though, that even in a vacuum-sealed chamber with ultra-specialised mirrors, each reflection saps 30% of the light's energy. By the time the photons reach the wafer, less than 2% of the original EUV energy remains. Without enough power, reliability and precision plummet. One way to boost energy is to bombard the wafer with multiple doses of EUV light, a trick that slows down the chip-manufacturing process. The other approach is to increase the power of the photons. ASML's latest rig uses a light source that operates at 500 watts, nearly twice the power of its previous machines. To speed up production or to shrink feature sizes even further, the light source must get stronger. ASML currently has a road map to develop a one kilowatt light source. A more radical solution is to use a free-electron laser (FEL), where electrons travelling near the speed of light are manipulated to emit EUV radiation. The FEL process begins with a powerful electron gun that injects a beam of the particles into a miniature racetrack. The electrons then pass through a linear accelerator, which propels them to nearly the speed of light. Once accelerated, they enter a roughly 200-metre-long structure called an undulator, where a series of magnets generate a field whose polarity flips periodically. This wiggles the electrons, causing them to emit a beam of EUV photons with a specific wavelength. Nicholas Kelez, the boss of xLight, a Silicon Valley startup developing FEL-based lithography, described the technology as a more powerful and tuneable 'new light bulb" that he believes can be swapped into existing optical lithography machines. xLight expects to deliver the first commercial system within four years. Another research group, at the High Energy Accelerator Research Organisation (KEK) in Japan, has already demonstrated the ability to generate light at 20 micrometres (millionths of a metre)—far longer than the 13.5nm wavelengths ASML is capable of but a step towards refining the process. Chinese researchers are also exploring FEL technology in their quest to develop an independent EUV machine. Generating light using a FEL has some advantages over using lasers. The first is power: a lithography machine based on a FEL-based light source can be around six times more energy-efficient than a laser-plasma tool. Dispensing with molten-tin droplets also reduces the risk of contamination. Tuning such a machine for smaller wavelengths is also, at least theoretically, much easier: all that needs doing is tweaking the settings on the electron gun and the undulator. It would also be cheaper. A single FEL system can be repurposed to provide light for multiple lithography machines, allowing its operator to distribute the fixed costs across multiple chip-etching tools. Nakamura Norio from KEK estimates that the construction cost is around half that of a laser-based EUV tool and the running costs are around a fifteenth. For now, all this is theoretical. Whereas ASML's EUV machines are proving themselves in high-volume manufacturing, FEL-based lithography is still in the experimental phase. But in the high-stakes world of chipmaking, any edge is worth chasing. Curious about the world?

‘Agroterrorism weapon': How China-linked outbreaks disrupted life worldwide
Two Chinese nationals were reportedly accused of smuggling a "dangerous biological pathogen" into the United States for research at a University of Michigan Laboratory. The pathogen was said to have the potential to be used as an agricultural terrorism weapon. The US Department of Justice on Tuesday identified the pathogen as Fusarium graminearum. The US department said Fusarium graminearum is a fungus that was classified in scientific literature as a potential "agroterrorism weapon". In a statement, it said that the fungus causes "head blight" in some crops and is responsible for billions of dollars in economic losses globally each year. 'Head blight' is a disease of wheat, barley, maize, and rice. "Fusarium graminearum's toxins cause vomiting, liver damage, and reproductive defects in humans and livestock," the US Department of Justice said. The two accused Chinese nationals were identified as Yunqing Jian, 33, and Zunyong Liu, 34. According to an FBI criminal complaint, Zunyong Liu, 34, a researcher currently in China, brought the fungus into the US while visiting his girlfriend, Yunqing Jian, 33, in July 2024. They were charged in a criminal complaint "with conspiracy, smuggling goods into the United States, false statements, and visa fraud," said US Attorney Jerome F. Gorgon, Jr. Notably, a complaint is only a charge and is not evidence of guilt. China has been under the scanner for allegedly being responsible for the outbreak of several diseases and pandemics. The coronavirus pandemic is the latest example. Here are times when China was held responsible for a virus outbreak, epidemics and pandemics: The origin of bubonic plague has led to a heated debate among historians. According to Germany-based Max Planck Society, the plague first entered the Mediterranean in 1347 via trade ships transporting goods from the territories of the Golden Horde in the Black Sea. The rats on the ship brought with them the Black Death, the bubonic plague. The Black Death is considered one of the deadliest epidemics in human history. It sprea across Western Asia, Northern Africa, Middle East and Europe in 1346-53. Accoridng to the report, this first wave extended into a 500-year-long pandemic, the so-called Second Plague Pandemic, which lasted until the early 19th century. Even as the origins of the Second Plague Pandemic have long been debated, one of the most popular theories has supported its source in East Asia, specifically in China, the report added. Meanwhile, according to a New York Times report published in 2022, researchers found that the Black Death arrived in 1338 or 1339 near Issyk-Kul, a lake in a mountainous area just west of China in what is now Kyrgyzstan. "The plague first infected people in a small, nearby settlement of traders eight years before it devastated Eurasia, killing 60 percent of the population," the report added. It's alleged that the pandemic of 1957-1959, dubbed the Asian flu, emerged in East Asia. The Lancet Journal said the virus emerged in China in the winter of 1957 and spread rapidly worldwide via ships, aeroplanes, and trains. However, there are differing accounts of where the 1957 'Asian flu' pandemic, which was caused by the new influenza A (H2N2) virus, originated. According to Reuters, the US Centers for Disease Control and Prevention (CDC) states that the virus was first reported in Singapore in February 1957, before spreading to Hong Kong in April and the US in the summer. The pandemic killed 2 million people worldwide in a two-year period. The SARS coronavirus (SARS-CoV) was first identified in November 2002 in the Guangdong province of southern China, Reuters reported. The epidemic affected 26 countries and resulted in more than 8,000 cases in 2003. The World Health Organization (WHO) says that SARS cases were detected as early as November 2002 as part of an outbreak that emerged in China. It added that the pathogen causing the disease was identified as a coronavirus at the end of February 2003. The COVID-19 pandemic was also caused by SARS-CoV virus. However, the site of origin of the outbreak is still debated. On December 31, 2019, the Wuhan Municipal Health Commission in China had reported a cluster of cases of pneumonia in Wuhan, Hubei Province. A novel coronavirus was eventually identified. Since then, several theories have been tabled to understand the origin of COVID-19 pandemic. The current argument revolves around two theories: one is the scenario of laboratory leak where the pathogen escaped from a laboratory, the other is human contact with zoonotic diseases. China has been disputing the claims that the virus leaked from a Wuhan lab or that it originated in China. The country recently suggested that the COVID-19 virus may have originated in the US. "Substantial evidence suggested the COVID-19 might have emerged in the United States earlier than its officially-claimed timeline, and earlier than the outbreak in China," stated the white paper released by the official Xinhua news agency earlier this year.
