    Shanghai university launches new AI plus polymers platform

    A decades-long effort to reimagine polymer material development through artificial intelligence reached a major milestone this month, as researchers at Shanghai’s East China University of Science and Technology (ECUST) launched the third iteration of their groundbreaking AI plus Polymers platform. The new release marks a critical step forward in China’s transition from traditional, trial-and-error based materials R&D to a modern, intelligent and precision-driven design ecosystem.

    Unlike early versions of the tool, the v3.0 platform delivers comprehensive upgrades across every core layer of its infrastructure, built specifically to address the wide-ranging research and development needs of academic and industrial teams working with polymer materials. It now hosts a massive curated database of 7.6 million specialized polymer-related entries, integrates more than 80 tailored AI models, and features over 10 purpose-built algorithms designed exclusively for polymer science applications. According to the ECUST research team, these improvements enable far more efficient intelligent design of high-performance resins, organic optoelectronic materials, and advanced composite materials, supported by an enhanced human-computer interaction framework that streamlines workflows for both researchers and industry practitioners.

    ECUST’s journey in AI-accelerated polymer research stretches back more than a decade, to 2013, when the team pioneered the country’s first AI-powered polymer research program. Over the years, they have built an entirely new research paradigm dubbed “AI for polymers”, which is fully protected by independent, indigenous intellectual property rights held by the university team.

    Since the platform’s first public launch in March 2023, it has seen rapid adoption across China’s advanced manufacturing and materials sectors. To date, more than 10 national aerospace research institutes and over 60 domestic new chemical material enterprises have integrated the platform into their regular R&D operations. Real-world applications of materials developed through the “AI for polymers” paradigm are already delivering impact: high-performance resins and advanced conductive adhesives created with the platform’s support have already entered full-scale industrial use. Most notably, a novel resin with unique properties—high-temperature resistance, superior toughness, and easy processability—has already been deployed in key components of China’s aerospace and advanced precision equipment, the team confirmed.

    Looking ahead, the ECUST team has set ambitious expansion goals for the paradigm-shifting technology. “Our team’s vision is to expand the new AI paradigm to broader fields, including polymer structural materials, functional materials, and biomedical materials,” said Lin Jiaping, lead scientist of the research program. “Also, we aim to comprehensively empower the design and development of polymer materials and promote the digital transformation of the entire industry through artificial intelligence.”

  • Watch: Skydiver crashes into jumbotron at US football game

    Watch: Skydiver crashes into jumbotron at US football game

    A planned pre-game skydiving demonstration at a Virginia Tech University football event took an unexpected turn on Saturday, when one airborne performer veered off course and collided directly with the stadium’s massive overhead jumbotron.

    Witnesses captured the dramatic moment on camera, showing the skydiver becoming tangled in his parachute lines after the impact, leaving him suspended dozens of feet above the stadium playing field. Emergency first responders were already on standby for the event, and they immediately launched a coordinated rescue operation to extract the stranded skydiver from the scoreboard structure.

    In a statement released after the incident, local emergency management officials confirmed that the skydiver escaped the frightening collision without any reported injuries. The accident prompted a brief delay to the start of the scheduled football contest while the rescue was completed, and the event resumed as planned once the area was cleared. Organizers have not yet announced whether they will revisit safety protocols for future aerial demonstration events held at the venue.

  • Trump tariff refunds begin but consumers likely to miss out

    Trump tariff refunds begin but consumers likely to miss out

    More than two months after the U.S. Supreme Court struck down a sweeping set of Trump-era tariffs, the current Trump administration has kicked off what historians and trade analysts describe as the largest tariff repayment initiative in U.S. history. Eligible importing companies can now submit claims online to recover the billions in duties they paid, plus accumulated interest, under the administration’s controversial “Liberation Day” tariffs.

    The legal path for refunds cleared in March, when the U.S. Court of International Trade ordered U.S. Customs and Border Protection (CBP) to return the full $160 billion (around £121 billion) collected from importers under the tariffs, which were imposed using the 1977 International Emergency Economic Powers Act (IEEPA). The court’s ruling puts roughly 330,000 registered importers in line to potentially claw back at least a portion of the funds they paid.

    In a March ruling, Judge Richard Eaton emphasized that “All importers of record whose entries were subject to IEEPA duties are entitled to the benefit” from the Supreme Court’s February decision. When the official online claims portal, branded the Consolidated Administration and Processing of Entries (Cape), went live earlier this month, more than 56,000 importers had already completed their applications within the first week, submitting claims totaling $127 billion, according to early CBP data.

    CBP officials designed the Cape platform to streamline the refund process, allowing importers to submit a single bulk claim for all eligible duties rather than filing separate requests for each individual imported shipment. Approved claimants can expect to receive their full refund plus applicable interest within 60 to 90 days of approval, a CBP spokesperson confirmed.

    But the structure of the program has sparked widespread frustration, as ordinary consumers who bore the indirect cost of the tariffs through higher retail prices are excluded from direct compensation. The tariffs pushed up prices on a huge range of imported goods, from raw materials used by small businesses to finished consumer products, but only registered importing companies are eligible to file claims. While consumers could theoretically see indirect benefits if companies choose to pass recovered funds back to shoppers through lower prices, few firms have announced plans to do so, leaving millions of affected Americans with no path to relief.

    In response to the exclusion, hundreds of consumers have launched class-action lawsuits against major retailers and brands, arguing that any refunds businesses receive should be passed through to the customers that ultimately paid the tariff costs. Federal suits have already been filed against EssilorLuxottica, the parent company of Ray-Ban, global delivery firm FedEx, and wholesale retail giant Costco in multiple U.S. district courts. Costco is an outlier among major companies: chief executive Ron Vachris has confirmed the retailer plans to pass any tariff refunds back to consumers “through lower prices and better values.”

    For small business owners who absorbed higher supply costs, the exclusion is a particularly bitter blow. Sue Johnson, a small-batch lamp designer based in the Midwest, told the BBC that her key material supplier doubled prices immediately after the tariffs went into effect, cutting her profit margins dramatically. “Maybe [the importers] will get repaid, but I have no hope they’re going to refund me,” Johnson said, adding that she expects no relief from the current refund program.

    The issue of consumer compensation is further complicated by the uneven impact of tariffs on business pricing. Many importers only partially passed tariff costs through to consumers to stay competitive, meaning they absorbed a portion of the cost themselves. Tariffs also triggered secondary, hard-to-quantify costs for businesses, from higher debt loads taken on to cover upfront duty payments to lost sales from reduced consumer demand at higher price points.

    Top Trump administration officials have openly acknowledged that consumers are not expected to see direct benefits from the program. U.S. Trade Representative Jamieson Greer encouraged successful claimants last month to allocate any unexpected “windfall” refunds to worker bonuses rather than passing the money to consumers. Treasury Secretary Scott Bessent echoed that framing in February, saying “I got a feeling the American people won’t see it.”

  • Mother and six children die in Pennsylvania house explosion

    Mother and six children die in Pennsylvania house explosion

    A devastating domestic disaster has claimed the lives of a 34-year-old mother and her six young children in rural Clinton County, Pennsylvania, after an explosion sparked an out-of-control blaze that engulfed their entire residence, law enforcement officials confirmed this week.

    Local emergency dispatchers received initial reports of a large explosion at the single-family home in Lamar Township at 8:30 a.m. local time Sunday, according to an official statement from Pennsylvania State Police. When first responder fire crews arrived at the scene, they encountered the entire property fully engulfed in intense flames, making an immediate search for trapped residents impossible. All seven people inside the home at the time of the blast were later found dead.

    Authorities have identified the victims as Sarah B. Stolzfus, 34, and her six children — four boys and two girls between the ages of 3 and 11. Preliminary investigations point to an indoor propane leak as the likely trigger for the explosion, though official probes into the exact origin and cause of the incident remain active. The BBC has reached out to Pennsylvania State Police to request additional details and updates on the ongoing investigation.

    Footage captured by local media outlets on the scene shows thick black smoke billowing into the sky above the burning property, as the fire weakened the home’s structural framework and caused partial collapse before crews could bring the blaze under control.

    Neighbors described the terrifying moment of the explosion, with Christina Duck, a nearby resident, telling local broadcaster WNEP-TV that she was eating breakfast with her own daughter when the blast occurred. “I could feel it [the shockwave] and I got up and looked out the window, and I could see the flames through the windows, and I come running outside and within a minute the whole house was completely engulfed,” Duck recalled in her account of the incident.

    Duck added that neighbors who witnessed the blast immediately began running through the neighborhood to alert others and call 911, and fire crews arrived at the scene just minutes after the initial explosion. Still, the speed of the fire left no opportunity to save the home or the people trapped inside. “By the time they got here, there was no saving that house. It went up so fast,” she said.

  • Switzerland great Marcel Hug claims his ninth Boston Marathon wheelchair title and fourth straight

    Switzerland great Marcel Hug claims his ninth Boston Marathon wheelchair title and fourth straight

    On a crisp, sunlit Monday morning at the 130th running of the Boston Marathon, Swiss wheelchair racer Marcel Hug delivered yet another masterclass in endurance and competitive dominance, securing his ninth career title in the event and extending his consecutive winning streak to four straight victories.

    Starting temperatures hovering in the low 40s Fahrenheit created ideal racing conditions for the elite wheelchair field, and Hug wasted no time stamping his authority on the 26.2-mile course. Within just three miles of the starting gun, he had broken away from the pack, opening a 13-second gap over British veteran David Weir. By the race’s halfway mark, that advantage had ballooned to 55 seconds, leaving his closest competitors struggling to match his blistering pace.

    When he crossed the finish line, Hug’s unofficial time clocked in at 1 hour, 16 minutes and 6 seconds — a result that cements his standing as one of the most decorated athletes in Boston Marathon history. With nine titles to his name, he now sits alone in second place on the all-time men’s wheelchair leaderboard, trailing only South African icon Ernst van Dyk, who set the current record of 10 titles over a 13-year stretch between 2001 and 2014.

    American top contender Daniel Romanchuk crossed second with a time of 1:22:44, while Jetze Plat of the Netherlands rounded out the top three with a finish time of 1:24:13. In the women’s wheelchair division, Britain’s Eden Rainbow-Cooper claimed the top spot on the podium.

    Hug’s historic win in Boston extends an extraordinary run of form for the Swiss athlete that dates back to his 2022 victory at the Berlin Marathon. Across seven World Marathon Major events since that win, Hug has finished outside the top spot just once: he took second place at the 2024 New York City Marathon earlier this year, a rare blemish on an otherwise perfect stretch of elite competition.

  • Strong winds, cold air bring sandstorms to northern China

    Strong winds, cold air bring sandstorms to northern China

    China’s National Meteorological Center issued a renewed blue-level sandstorm alert on Monday, warning that a combination of powerful winds and an invading cold air mass would bring widespread dust and sand intrusion to large parts of the country’s northern region. The blue alert marks the lowest level in China’s four-tier national weather warning system, activated when meteorological conditions meet moderate-risk thresholds for hazardous weather.

    According to the center’s official forecast, the combined influence of the moving cold front and sustained strong winds will bring blowing sand and scattered dust events to multiple northern provincial-level regions between Monday and Tuesday. More severe full-scale sandstorms are projected to hit portions of the Inner Mongolia Autonomous Region and the Xinjiang Uygur Autonomous Region.

    Meteorological officials have outlined multiple risks stemming from this weather event: the poor air quality and reduced visibility will create disruptions for agricultural operations and ground transportation, elevate public health risks for residents with respiratory conditions, and increase the likelihood of wildfires in northern forest and grassland areas.

    In Beijing, the city’s emergency warning management agency announced it had lifted its local blue dust alert early Monday morning, after significant improvements in atmospheric visibility cleared the capital’s air of excessive particulate matter.

    The active cold air mass driving the sand event is also triggering sharp temperature drops across a wide swathe of China. On Monday alone, regions in Northeast China and areas along the Yellow and Yangtze river basins will see temperatures fall between 6 and 10 degrees Celsius, with some local areas recording temperature plunges of more than 10 degrees Celsius.

    From Monday through Thursday, the collision of cold and warm air masses will bring widespread rain and snow precipitation to central and eastern China. Portions of Inner Mongolia and Heilongjiang Province are forecast to see light to moderate snow or sleet, with isolated areas expected to experience heavy snowfall or full blizzard conditions.

  • PLA Air Force sends Y-20B aircraft to repatriate remains of CPV martyrs from ROK

    PLA Air Force sends Y-20B aircraft to repatriate remains of CPV martyrs from ROK

    In a solemn ceremony of national remembrance, the People’s Liberation Army Air Force has deployed a Y-20B large transport aircraft to undertake the mission of bringing home the 13th batch of remains of Chinese People’s Volunteers (CPV) martyrs from the Republic of Korea (ROK). This updated announcement was first published by China Daily on its official website, with the latest revision timestamped 14:30, April 20, 2026.

    The repatriation of CPV martyrs’ remains is an ongoing coordinated effort between China and the ROK that honors the sacrifice of service members who fought in the Korean War. For over a decade, successive batches of martyrs’ remains have been returned to their home country, allowing these fallen heroes who gave their lives defending national security and regional peace decades ago to finally be laid to rest on Chinese soil.

    The use of the domestically developed Y-20B, China’s indigenously built large military transport aircraft, for this mission carries profound symbolic meaning. It reflects the nation’s deep respect for its fallen heroes and underscores China’s commitment to honoring the legacy of those who sacrificed for the country. This mission also continues the long-standing tradition of respect for military sacrifice that unites the Chinese public in collective remembrance.

  • Gulf poised to move closer to China after the war

    Gulf poised to move closer to China after the war

    Nearly two months of open conflict stemming from the Iran war have sent deep, systemic shocks across the Gulf region, upending two core assumptions that have anchored regional stability for close to a century. For decades, the Gulf’s economic model flourished under a framework built on perceived geopolitical stability, reinforced by competitive policy incentives including zero-tax regimes, flexible regulatory frameworks, and a rapidly growing, diversified startup ecosystem. Parallel to this economic structure, the region’s security order rested on the decades-old oil-for-security pact with the United States, backed by a dense network of U.S. military installations and advanced defense hardware across the region.

    Today, both foundational pillars have suffered tangible erosion after weeks of cross-region missile and drone strikes that have hit all Gulf states. This new reality has forced Gulf capitals into a painful period of strategic re-evaluation, particularly over Washington’s reliability as a long-term security guarantor. As a result, the region is turning its gaze eastward with a new urgency that did not exist before the outbreak of war.

    In this post-conflict landscape, economic diversification is no longer just an ambitious long-term goal—it is a growing necessity for long-term survival. Among potential partners, China stands out as the most logical option for deepening cooperation, given its already massive and expanding economic footprint across the Gulf built on decades of growing trade, cross-border investment, and large-scale infrastructure partnerships.

    While the Sino-Gulf relationship is not without its inherent constraints, the sheer scale of Chinese economic engagement in the region has created a gravitational pull that can no longer be ignored. The bilateral partnership evolved into a formal comprehensive strategic alignment after Chinese President Xi Jinping’s landmark 2022 visit to Riyadh for the Gulf Cooperation Council (GCC) Summit. By 2025, annual multilateral trade between China and the GCC hit approximately $300 billion, cementing China’s position as the GCC’s largest single trading partner. Where Chinese investment was historically concentrated almost exclusively in the energy sector and large-scale port developments, the post-war shift is pushing both sides to explore far deeper economic integration across new sectors.

    The future of this expanding partnership is set to be shaped by three key sectors where China’s industrial leadership and Gulf capital create natural synergies. The first is green energy transition, a field where China already holds undisputed global dominance, controlling more than 80% of the world’s total solar panel manufacturing capacity. Chinese exports of wind turbine generators grew by roughly 50% in 2025, and the country accounts for 70% of global electric vehicle (EV) production—an alignment that perfectly matches Gulf nations’ long-term goals to diversify their economies away from overreliance on hydrocarbon exports. For Gulf states, partnering with Chinese firms is a pathway to access the cutting-edge technology needed to transform their domestic power grids and transportation sectors, with major Chinese brands including BYD, Geely, and Changan already positioned to lead this transition.

    The second area of growing cooperation is being enabled by the expansion of the BRICS+ framework, which provides a formal platform for cross-regional financial integration that can act as a hedge against overreliance on the Western-dominated global financial system. While a full shift to a yuan-denominated oil trade system remains distant due to the entrenched dominance of the petrodollar, both sides have already begun testing new alternative mechanisms. For example, the mBridge project, a joint initiative between the central banks of China and the United Arab Emirates, is currently piloting a central bank digital currency (CBDC) platform that allows cross-border trade settlements to bypass Western intermediary banks entirely. These trials allow Gulf states to diversify their financial risk exposure while preserving their long-standing traditional economic and political ties with Western powers.

    The third key area of collaboration centers on China’s flagship Belt and Road connectivity project, the China-Pakistan Economic Corridor (CPEC). With a total cumulative investment of roughly $62 billion, CPEC offers a strategic solution to China’s long-standing “Malacca Dilemma” — the geopolitical vulnerability that sees roughly 80% of China’s total oil imports pass through the narrow Strait of Malacca, a chokepoint vulnerable to external disruption. By expanding investment in CPEC and the deep-water Gwadar Port, Gulf nations can integrate their existing maritime trade routes with overland corridors leading directly into Central Asia. This positioning allows Gulf states to reemerge as central nodes in a new multipolar global trade map, a particularly valuable strategic shift given that 42% of China’s total 2025 crude oil imports came from the Middle East, with Saudi Arabia accounting for 14% and the UAE contributing 7% of that total.

    That said, it is critical to acknowledge clear boundaries to the growing Sino-Gulf closeness, most notably the vast structural gap in military commitments between China and the U.S. in the region. While the post-war security shock has acted as a major wake-up call for Gulf leadership, it should not be misinterpreted as a desire to fully replace the United States with China as the region’s primary security partner.

    Gulf leadership has long been deeply pragmatic, with no interest in exchanging one form of single-partner dependency for another. The security domain remains the single most significant barrier to a full strategic shift away from the U.S. Currently, the U.S. maintains a formidable military presence of between 40,000 and 50,000 personnel across roughly 10 regional countries, with Qatar’s Al Udeid Air Base alone hosting more than 10,000 U.S. troops. In stark contrast, China’s only military footprint in the broader region is a single logistical support base in Djibouti, consistent with Beijing’s long-standing foreign policy principle of non-interference in other nations’ internal affairs. Even in defense procurement, the gap between the two powers remains substantial and cannot be closed quickly. While China has grown into a more prominent global arms exporter, it still lags far behind the U.S. in regional market share.

    Data from the Stockholm International Peace Research Institute (SIPRI) underscores this gap: between 2021 and 2025, the U.S. accounted for 54% of all arms imports to the Middle East, with Saudi Arabia — the largest global recipient of U.S. arms exports — importing 12% of total U.S. defense exports over that period. By comparison, Chinese arms exports to the entire Middle East between 2016 and 2025 totaled just 732 million in Trend-Indicator Value (TIV), SIPRI’s standardized metric for tracking defense trade trends. That is a tiny fraction of the $19.5 billion TIV in U.S. arms exports to the region over the same 10-year period. While Chinese unarmed drones have grown in popularity for their lack of attached political conditions, they cannot yet match the fully integrated air and missile defense systems that the U.S. military provides to regional allies.

    In the end, the post-war regional shift is not a radical, binary pivot from Washington to Beijing. Instead, it is a deliberate push by Gulf middle powers to gain greater strategic autonomy. Gulf states do not see China as a replacement for the U.S., but rather as a necessary strategic hedge. By diversifying both their security and economic partnerships, they are building a multipolar “insurance policy” that carries far less long-term risk than continuing to rely entirely on a single, increasingly fraying security umbrella.

    This logic of seeking alternatives to Western-dominated frameworks is not about replacement; it is about building a more resilient multipolar foundation for the region that delivers lower long-term costs and greater economic benefits for Gulf states’ long-term survival. This shift eastward is a calculated, pragmatic response to a changing global order where the old certainties of the decades-old oil-for-security pact no longer hold.

  • Canada: Ties to US are ‘weaknesses we must correct’

    Canada: Ties to US are ‘weaknesses we must correct’

    For decades, Canada’s deep integrated economic and trade relationship with the United States has been widely framed as one of the country’s greatest economic assets, driving cross-border investment, job growth, and market access for Canadian manufacturers and resource exporters alike. But that long-held consensus is shifting dramatically, according to Canadian Prime Minister Mark Carney, who is calling for urgent course correction after sweeping changes to U.S. trade policy transformed the once-advantageous partnership into a critical vulnerability for Canada’s economic future.

    In recent remarks, Carney argued that evolving trade priorities out of Washington have eroded the stability that once made close bilateral ties a boon for Canadian economic growth. What once allowed Canadian businesses to reliably access the world’s largest single consumer market has now become a source of systemic risk, he said, leaving Canada overly exposed to sudden shifts in U.S. trade rules, tariff policy changes, and politically driven trade disputes that can disrupt domestic economic activity with little warning.

    Carney’s comments mark a notable shift in Canadian discourse around bilateral relations, opening a new conversation about the need for Canada to diversify its trade partnerships, reduce its overreliance on the U.S. market, and strengthen domestic economic resilience to insulate the country from future trade policy changes originating south of the border. The prime minister framed the push for correction as a pragmatic response to a changed global trade landscape, rather than a rupture in bilateral relations, noting that adapting to Washington’s new policy direction is a necessary step to protect Canada’s long-term economic sovereignty and prosperity.

  • World Industrial Design Association launched in Shanghai

    World Industrial Design Association launched in Shanghai

    In a landmark move for global industrial design collaboration, the World Industrial Design Association (WIDA) officially launched its operations in Shanghai, marking a new chapter for cross-border innovation and industry-academia partnership in the global design sector.

    Approved by China’s State Council, the new global body is co-founded by a diverse coalition of stakeholders, including the University of Shanghai for Science and Technology, the China Industrial Design Association, Shanghai Jiao Tong University, alongside a wide range of design organizations, private enterprises, academic institutions, and industry experts from across the globe.
