  • New optical chip can help advance generative AI

    New optical chip can help advance generative AI

    Researchers at Shanghai Jiao Tong University have unveiled a groundbreaking optical computing chip that promises to transform the landscape of generative artificial intelligence. Dubbed LightGen, this innovative all-optical chip represents a significant leap forward in addressing the enormous computational and energy challenges facing next-generation AI systems.

    The research breakthrough, published as a featured paper in the prestigious journal Science on December 20, 2025, marks the first successful development of an all-optical computing chip capable of supporting large-scale semantic and visual generative models. This achievement comes at a critical juncture when generative AI applications are expanding into increasingly complex real-world scenarios, from instant text-to-image conversion to rapid video creation.

    Unlike conventional electronic chips that process information using electrons within transistors, LightGen harnesses the natural properties of light to achieve unprecedented processing speeds and parallelism. The technology fundamentally reimagines computational architecture by overcoming three previously insurmountable bottlenecks: integrating millions of optical neurons on a single chip, achieving comprehensive all-optical dimensional transformation, and developing specialized training algorithms for optical generative models that operate independently of ground truth data.

    According to lead researcher Chen Yitong, assistant professor at Shanghai Jiao Tong University’s School of Integrated Circuits, LightGen’s architecture enables a complete ‘input-understanding-semantic manipulation-generation’ cycle entirely through optical processes. The system can extract and represent semantic information from input images, then generate new media data under semantic control—effectively enabling light to both ‘understand’ and ‘cognize’ complex information patterns.

    Experimental results demonstrate LightGen’s capability to perform high-resolution image semantic generation, 3D modeling, high-definition video generation, and sophisticated semantic control operations. The chip supports diverse large-scale generative tasks including advanced denoising and feature transfer applications.

    Performance evaluations conducted under rigorous computational standards revealed that LightGen achieves generation quality comparable to leading electronic neural networks like Stable Diffusion and NeRF, while delivering staggering efficiency improvements. Testing showed computational and energy efficiency enhancements of two orders of magnitude compared to top-tier digital chips, even when using relatively outdated input devices. Theoretical projections suggest that with advanced devices, LightGen could achieve computational power improvements of seven orders of magnitude and energy efficiency improvements of eight orders of magnitude.

    This development signals a potential paradigm shift in the post-Moore’s law era, where global research efforts are increasingly focused on next-generation computing solutions. As generative AI becomes more deeply integrated into production systems and daily life, LightGen opens new pathways for developing high-speed, energy-efficient generative intelligent computing systems that could fundamentally reshape AI implementation across industries.

  • Deputies now more engaged in legislation

    Deputies now more engaged in legislation

    China’s legislative process is witnessing increased participation from people’s congress deputies nationwide, marking significant progress in the implementation of whole-process people’s democracy. Huang Haihua, spokesman for the NPC Standing Committee’s Legislative Affairs Commission, confirmed on Friday that deputies are actively contributing to lawmaking through substantive suggestions and participating in enforcement inspections.

    The engagement mechanism has yielded tangible results, with 19 legislative items connected to 43 motions from deputies either approved, currently under review, or incorporated into the legislative planning framework. The legislative body has particularly integrated deputy input across multiple domains including environmental protection, private sector development, legal education, national parks, cybersecurity, and anti-unfair competition legislation.

    Huang emphasized the comprehensive approach to deputy involvement, noting that “we’ve invited deputies, particularly those with relevant expertise, to participate directly in legislative activities and share their perspectives personally. This has significantly enhanced our communication channels and collaborative engagement.” Regular briefings now provide updates on how deputy suggestions are incorporated into draft laws, creating a systematic feedback loop.

    These developments operationalize the amended Law on Deputies to the NPC and to Local People’s Congresses at Various Levels, which took effect on March 12, 2025. The measures aim to progressively expand both the scope and depth of deputy participation in legislative work, while creating improved mechanisms for gathering public opinions and integrating wisdom from diverse sectors of society.

    The upcoming NPC Standing Committee session, scheduled from Monday to Saturday in Beijing, will review several significant legislative items concerning economic development and livelihood issues. The agenda includes a draft amendment to the Civil Aviation Law proposing new airworthiness certification standards for unmanned aerial vehicles alongside enhanced passenger protection and flight safety measures.

    Addressing persistent safety concerns, lawmakers will consider draft legislation establishing a comprehensive risk identification system and skill enhancement requirements for employees in the hazardous chemicals sector, where accidents continue to occur in some regions.

    Additional items slated for review include a draft law on childcare services and legislation governing activities and environmental protection in Antarctica, alongside deliberations regarding the fourth plenary session of the 14th NPC.

  • US bombs Islamic State targets in Syria after attack on personnel

    US bombs Islamic State targets in Syria after attack on personnel

    In a decisive military response, the United States executed a series of airstrikes against ISIS targets in Syria late Friday. The operation, officially designated ‘Operation Hawkeye Strike,’ comes as direct retaliation for the December 13th ambush in Palmyra that resulted in the deaths of three American personnel—two soldiers and one civilian interpreter.

    Secretary of War Pete Hegseth publicly announced the offensive via social media platform X, characterizing the action as a measured response rather than an escalation toward broader conflict. ‘This is not the beginning of a war,’ Hegseth stated. ‘It is a declaration of vengeance.’ His accompanying message delivered a stark warning to adversaries: ‘If you target Americans – anywhere in the world – you will spend the rest of your brief, anxious life knowing the United States will hunt you, find you, and ruthlessly kill you.’

    The Syrian government, through its foreign ministry, issued a statement reaffirming its commitment to combating Islamic State militants. This alignment of interests appears to extend to the highest levels of leadership, with US President Donald Trump noting on his TruthSocial account that Syrian President Ahmed al-Sharaa expressed ‘full support’ for the operation.

    According to Pentagon reports, the initial provocation occurred when US personnel engaged in a meeting with local leaders in Palmyra were ambushed by an attacker subsequently identified as an IS sympathizer within Syrian security forces. US Central Command confirmed its troops responded immediately, neutralizing the gunman responsible.

    The current US military presence in northern Syria consists of approximately 1,000 troops dedicated to counter-ISIS operations. This retaliatory strike underscores the persistent security challenges facing American forces engaged in ground engagement missions throughout the region.

  • HK bids farewell to Tai Po blaze’s fallen firefighter

    HK bids farewell to Tai Po blaze’s fallen firefighter

    Hong Kong observed a day of profound mourning on Friday as the city paid final respects to Firefighter Ho Wai-ho, who made the ultimate sacrifice during last month’s catastrophic Tai Po residential fire that claimed 160 lives. The solemn ceremonies brought together government leaders, emergency personnel, and grieving citizens in a powerful display of communal solidarity.

    The formal funeral service, organized by the Fire Services Department at Hung Hom’s Universal Funeral Parlour, commenced at 10 am with Chief Executive John Lee Ka-chiu joining senior officials, Ho’s heartbroken family, and his fellow firefighters. The 37-year-old hero sustained fatal injuries on November 26 while conducting rescue operations at Wang Fuk Court in Tai Po district.

    In recognition of his extraordinary bravery, the Fire Services Department posthumously promoted Ho to the honorary rank of senior fireman. Having joined the department in 2016 and stationed at Sha Tin, Ho built a distinguished nearly nine-year career marked by exceptional dedication and participation in numerous critical rescue missions.

    Public admiration manifested early as residents began gathering outside the funeral parlor by 8 am, many bringing floral tributes to honor the fallen first responder. The subsequent procession featured a fire-truck-turned-hearse carrying Ho’s flag-draped coffin, which paused at approximately 11:10 am near the scene of the tragic blaze for a poignant memorial ceremony. Firefighters stood at solemn attention while officials bowed in respect, with nearby footbridges filled with mourning citizens.

    Among those paying respects was a Ms. Lee from adjacent Kwong Fuk Estate, who came to express gratitude for Ho’s sacrifice. She recounted how the acrid smoke from the November fire had permeated her home, creating an enduring sensory memory of the disaster.

    The procession then proceeded to Sha Tin Fire Station, where Ho had been based. There, personnel from across Hong Kong bowed collectively as a fire bell sounded four times—three short rings followed by one long—symbolically releasing Ho from his duties. The final journey concluded at Gallant Garden in Wo Hop Shek Cemetery, the resting place reserved for government servants who die in service to Hong Kong.

    At approximately 1:10 pm, six firefighters and two pallbearers carried Ho’s coffin to his final resting place, followed by his brother holding a portrait and his bereaved fiancée. In a touching final ritual, the flag covering the coffin was carefully folded and Ho’s service helmet was placed atop the lid, marking the formal end of his watch.

  • Students to benefit from direct flights

    Students to benefit from direct flights

    The restoration of direct air connectivity between India and China after a five-year hiatus is catalyzing a significant resurgence in bilateral exchanges, with educational and cultural ties emerging as primary beneficiaries. This aviation breakthrough, officially commencing in October 2025 with IndiGo Airlines’ Kolkata-Guangzhou route, has dramatically reduced travel barriers that previously hampered academic collaboration.

    Indian students pursuing educational opportunities in China are experiencing substantial relief from previously exorbitant travel costs and logistical complexities. Priyanshu Yadav, who recently completed advanced Chinese language studies at Tsinghua University, attested to the transformative impact: ‘Travel expenses have been reduced to less than half, eliminating the need for third-country transits that previously cost approximately $430 for one-way journeys.’

    The renewal of direct routes—including China Eastern Airlines’ Shanghai-New Delhi connection and Air India’s planned 2026 resumption of Delhi-Shanghai services—has reinvigorated institutional academic partnerships. Prestigious institutions including Jawaharlal Nehru University and Visva-Bharati University’s Cheena Bhavana (India’s oldest Chinese studies center) are actively reestablishing formal ties with Chinese counterparts like Fudan and Tsinghua Universities.

    Professor Huang Yinghong of O.P. Jindal Global University emphasized the multidimensional advantages: ‘The elimination of third-country transit saves time, energy, and financial resources while symbolizing improved bilateral relations.’ This sentiment is echoed by academic leaders anticipating renewed physical exchanges of faculty and students by July 2026, reviving cultural programs encompassing tai chi, calligraphy, Kathak dance, and yoga that were maintained online during the connectivity gap.

    The diplomatic dimension continues to develop with China’s recent implementation of an online visa application system for Indian travelers, further streamlining cross-border educational mobility. As Ambassador Xu Feihong noted, these developments reflect mutual commitment to strengthening cooperation across educational, cultural, and people-to-people exchanges, marking a new chapter in Sino-Indian relations through the prism of academic collaboration.

  • High-speed passenger train kills 7 elephants crossing railway tracks in northeast India

    High-speed passenger train kills 7 elephants crossing railway tracks in northeast India

    A devastating railway collision claimed the lives of seven wild Asiatic elephants and injured a calf in northeastern India’s Assam state during the early hours of Saturday. The Rajdhani Express train, transporting 650 passengers from Sairang to New Delhi, struck the elephant herd while traversing through forested terrain approximately 78 miles southeast of Guwahati, Assam’s capital.

    According to Indian Railways spokesman Kapinjal Kishore Sharma, the locomotive operator detected the massive herd of approximately 100 elephants and immediately engaged emergency braking systems. Despite these preventive measures, the high-speed passenger train could not avoid impact with multiple animals. The collision resulted in the derailment of five coaches and the engine, though remarkably no human passengers sustained injuries.

    Veterinary specialists conducted postmortem examinations on the deceased elephants, with burial procedures scheduled for later the same day. Railway authorities confirmed that the accident occurred outside designated elephant crossing corridors, though the region is known for frequent elephant movements.

    Following the incident, railway personnel separated the unaffected coaches, allowing the main train to continue its journey to New Delhi. Approximately 200 passengers from the derailed compartments were transferred to Guwahati via alternative transportation.

    This tragedy highlights an ongoing conservation challenge in Assam, which hosts an estimated 7,000 wild Asiatic elephants—among India’s highest population densities for the species. Since 2020, train collisions have killed at least a dozen elephants statewide. The problem intensifies annually during harvest season, when elephants increasingly venture into human-occupied areas near railway tracks.

  • US tech enabled China’s surveillance empire. Now Tibetan refugees in Nepal are paying the price

    US tech enabled China’s surveillance empire. Now Tibetan refugees in Nepal are paying the price

    KATHMANDU, Nepal — The iconic Boudhanath Stupa, with its serene Buddha eyes gazing over Nepal’s capital, once symbolized sanctuary for Tibetans fleeing Chinese persecution. Today, this spiritual haven exists under the unblinking gaze of thousands of Chinese-made surveillance cameras that monitor every movement in what has become one of the world’s most intensely monitored refugee communities.

    An Associated Press investigation reveals how China has transformed Nepal into a testing ground for its global surveillance exports, with technology originally developed by American companies now being deployed to suppress Tibetan dissent. Through thousands of government procurement documents, corporate materials, and interviews with over 40 sources, AP documented how Chinese technology firms have established comprehensive monitoring systems across at least 150 countries worldwide.

    The surveillance architecture in Nepal includes facial recognition cameras, AI-powered tracking systems, and digital communication networks provided by Chinese companies like Hikvision, Dahua, and Uniview—many using technology originally developed by U.S. firms. This digital infrastructure has effectively crushed the once-vibrant Free Tibet movement, reducing annual refugee arrivals from thousands to single digits.

    Chinese companies now offer complete surveillance suites with few restrictions on usage or customers. According to Sheena Greitens, a political scientist at the University of Texas at Austin, “China pitches itself as a global security model with low crime rates, contrasting its record with the United States. They’re certainly exporting the tools and techniques that are very important to authoritarian rule.”

    The investigation found that American technology transfer played a crucial role in China’s surveillance capabilities. Companies like HP, IBM, and Motorola initially provided technology through joint ventures and research partnerships in China, only to see their Chinese partners become global competitors in the surveillance industry.

    The impact on Tibetans in Nepal has been devastating. The population has plummeted from over 20,000 to less than half that number today. Those who remain live in constant fear, with predictive policing systems allowing authorities to identify and arrest potential protesters before demonstrations even occur.

    Sonam Tashi, a 49-year-old former protester, described how those considered likely to protest are picked up in advance around sensitive dates. “There are cameras everywhere,” he said while attempting to secure his 10-year-old son’s escape to India. “There is no future.”

    China’s Foreign Ministry denied allegations of coercing Western companies or collaborating with Nepal to surveil Tibetans, calling such claims “sheer fabrication driven by ulterior motives.” Neither the Nepali government nor Chinese-controlled Tibetan authorities responded to requests for comment.

    The surveillance network extends beyond urban centers to Nepal’s northern border regions, where China has constructed observation domes and monitoring systems that effectively seal the once-porous frontier. These installations are part of what Chinese officials term a “Great Wall of Steel” featuring fences, sensors, and AI-powered drones.

    For Tibetan refugees, the message is clear: silence has become survival. As one café owner anonymously stated, “Now you can only be Tibetan in private.” Another refugee, Namkyi, arrested at 15 for protesting Chinese rule, summarized the reality: “Even though we are free, the surveillance cameras mean we’re actually living in a big prison.”

  • US terminates green card lottery as it totes ‘Trump Gold Card’ fees

    US terminates green card lottery as it totes ‘Trump Gold Card’ fees

    In a significant policy shift, the Trump administration has announced the immediate suspension of the Diversity Visa Lottery Program (DV-1), citing national security concerns following a tragic shooting incident. The decision comes after investigators identified Claudio Neves Valente, a 48-year-old Portuguese national, as the perpetrator behind a mass shooting at Brown University and the subsequent killing of an MIT professor. Secretary of Homeland Security Kristi Noem confirmed that Valente had entered the United States through the diversity lottery system in 2017 and was granted permanent residency.

    The administration’s move coincides with the controversial launch of premium immigration options. Commerce Secretary Howard Lutnick revealed the successful generation of $1.3 billion within days through the sale of ‘Trump Gold Cards,’ which offer expedited permanent residency. The program requires a $15,000 processing fee, a $1 million contribution to the United States, and successful background checks for applicants seeking accelerated residency status.

    Furthermore, the administration is introducing an even more exclusive ‘Trump Platinum Card’ tier, demanding a $5 million contribution alongside the processing fee. This premium option grants holders the ability to spend up to 270 days annually in the United States without being subject to U.S. taxes on foreign-sourced income.

    While the administration presents these measures as enhanced security protocols, critics argue the timing suggests financial motivations. The diversity lottery, established in 1995, has historically provided up to 55,000 permanent resident visas annually to individuals from countries with traditionally low immigration rates to the United States. This recent suspension follows previous immigration restrictions targeting several Arab and African nations, which the administration justifies as necessary for vetting and screening purposes, though opponents contend these policies disproportionately affect Muslim-majority regions.

  • Three killed in Taipei metro attacks, suspect dead

    Three killed in Taipei metro attacks, suspect dead

    Taipei was shaken by a series of coordinated attacks at multiple metro stations on Friday, resulting in three civilian fatalities and multiple injuries before the suspected perpetrator was found dead in an apparent suicide. The incident has triggered heightened security alerts across Taiwan.

    According to official reports from Taipei’s Fire Department, the attacks occurred at both Taipei Main Station and Zhongshan Station, involving the deployment of smoke grenades and stabbings. Taiwanese Premier Cho Jung-tai confirmed the incidents were ‘a deliberate act,’ though investigators have not yet determined a specific motive.

    The suspect, identified as a 27-year-old male, wore a gas mask and bulletproof vest during the assaults. Witness accounts describe him throwing multiple canisters that released thick clouds of white smoke while armed with a knife. One heroic victim lost his life while attempting to subdue the attacker at Taipei Main Station.

    Mayor Chiang Wan-an revealed the suspect was previously wanted for evading military service and reportedly jumped from a building to evade capture. His death was subsequently confirmed by authorities.

    Medical reports indicate victims suffered from cardiac arrest, stab wounds, and blunt force trauma. Five injured individuals received medical treatment following the attacks.

    In response to the violence, Taiwanese authorities have implemented enhanced security measures at critical transportation infrastructure nationwide, including railways, highways, and airports. President Lai Ching-te pledged a thorough investigation and assured citizens that ‘there will be no leniency’ in ensuring public safety.

    This tragic event marks the most significant violent incident on Taipei’s metro system since 2014, when a stabbing spree resulted in four deaths, disrupting the island’s reputation for public safety.
