    Chinese-led team discovers nitrogen-bearing organics in lunar soil, shedding light on early solar system

    For decades, scientists have chased clues about how the raw materials for life first arrived on the early Earth, and a groundbreaking new discovery from a Chinese-led international research team has brought that story into sharper focus than ever before. In a first for planetary science, the team has successfully identified multiple nitrogen-bearing organic compounds on the surfaces of lunar soil grains brought back to Earth by China’s Chang’e 5 and Chang’e 6 missions, opening new windows into how organic matter moved through the early solar system. The team’s findings, which include contributions from the Institute of Geology and Geophysics of the Chinese Academy of Sciences, the University of New Mexico, and Changsha University of Science and Technology, were officially published in the peer-reviewed journal *Science Advances* on April 10, 2026.

    The longstanding core hypothesis among planetary scientists holds that asteroids and comets acted as cosmic delivery couriers in the chaotic early days of the solar system, shuttling critical organic compounds and life-essential elements—including carbon, nitrogen, oxygen, phosphorus, and sulfur—to the rocky terrestrial planets of the inner solar system. These deposited materials, researchers argue, likely supplied many of the fundamental chemical building blocks that allowed life to emerge and evolve on early Earth. But tracing this history has proven extraordinarily difficult on our home planet: billions of years of constant geological activity, tectonic shifts, and biological processes have erased nearly all traces of these earliest organic inputs. The Moon, by contrast, has almost no geological activity, making it a perfectly preserved time capsule that retains 4.5 billion years of solar system history, including records of these ancient organic delivery events.

    Prior studies of lunar samples collected by NASA’s Apollo missions successfully detected simple carbon- and hydrogen-containing organic compounds in lunar regolith, but concrete evidence of nitrogen-bearing organics had never been found—creating a critical gap in the hypothesis that organic materials were delivered to the inner solar system via asteroid and comet impacts. To fill this gap, the research team deployed cutting-edge analytical techniques: high-resolution microscopy, energy-dispersive spectroscopy, and high-precision spectroscopic methods, which allowed them to map and characterize tiny organic deposits on individual lunar soil grains at a micro scale.

    Their analysis confirmed that the organic matter found on the lunar grain surfaces is primarily composed of carbon, nitrogen, and oxygen, with no uniform fixed chemical structure. “In some of the samples we tested, we detected amide functional groups, a key structural component of biological molecules like proteins,” explained Dong Mingtan, first author of the study and a PhD candidate at the Institute of Geology and Geophysics, Chinese Academy of Sciences. “This confirms these materials are not just inert graphitized carbon—they have undergone complex chemical reprocessing that brings their structure much closer to the type of organic molecules that could be used by developing life.”

    Further isotopic analysis revealed that the hydrogen, carbon, and nitrogen isotopic compositions of these lunar organics are generally lighter than the same organic materials found in carbonaceous chondrites (primitive asteroid fragments that fall to Earth) and directly collected asteroid samples. Dong noted that this specific isotopic signature matches the expected outcome of impact processing: when asteroids or comets collide with the Moon, extreme impact heat triggers the decomposition and volatilization of organic molecules from the impacting extraterrestrial body, leading lighter isotopes to preferentially condense and deposit onto lunar mineral grains.

    In another landmark finding, the team also identified clear signatures of solar wind implantation in the lunar organic matter for the first time. “We observed distinct shifts in hydrogen isotopic composition and hydrogen-to-carbon ratios close to the surfaces of the soil grains, which matches the pattern one would expect from prolonged exposure on the lunar surface and continuous irradiation by solar wind particles,” said Hao Jialong, the study’s corresponding author and a senior engineer at the Institute of Geology and Geophysics. “Crucially, these patterns rule out the possibility that the organic compounds came from terrestrial contamination after the samples were returned to Earth.”

    The research team’s work outlines a clear, continuous evolutionary pathway for lunar organic matter: initial delivery by extraterrestrial impacting bodies, followed by chemical restructuring driven by impact heat, and final modification by long-term lunar space weathering. This sequence provides transformative new insights into the evolution of small solar system bodies and the full history of organic delivery to the inner solar system. Beyond advancing our understanding of early solar system evolution, the new analytical techniques developed for this research have broad applications for future deep space exploration. Dong emphasized that these methods can be adapted to identify microscale organic matter and trace its evolutionary history in samples collected by future sample return missions—including China’s Tianwen 2 mission, which is scheduled to return the country’s first asteroid samples to Earth by the end of 2027.

  • China’s cyberspace regulator imposes new rules on livestream tipping services

    China’s cyberspace regulator imposes new rules on livestream tipping services

    China’s top cyberspace governance body has introduced a sweeping set of new regulatory requirements for livestream tipping services, aiming to bring greater transparency to the fast-growing online streaming sector and strengthen protections for underage users, the regulator announced in an official notice published on Monday.

    The Office of the Central Cyberspace Affairs Commission laid out 11 specific mandates that all major online platforms offering livestream services must follow to govern commercial monetization through viewer tipping, a practice that has generated billions in revenue for platforms and content creators but also drawn widespread criticism over exploitative practices and youth overspending.

    Under the new framework, platforms that provide top-up services, host viewer tipping, publish creator popularity ranking lists, or design interactive monetization features are required to publish clear, straightforward terms of service that are easily accessible to all users. The rules explicitly ban platforms from hiding critical fee and tipping details behind multiple redirects or burying them in overly long, jargon-heavy user agreements that confuse consumers about the costs of their actions.

    The regulator also introduced strict penalties for violators that break tipping-related rules. For livestream accounts that have previously committed violations and had their monetization privileges revoked, a three-month waiting period after the conclusion of their initial punishment must pass before privileges can be restored. If an account is temporarily muted for rule-breaking, its ability to earn revenue through viewer tipping must remain suspended for a period two to three times longer than the original mute penalty.

    Additional user privacy protections are also included in the new rules. Platforms are prohibited from publicly sharing individual users’ tipping, top-up and gift purchase spending data without explicit prior consent from the user. Platforms are also required to step up content moderation for tipping-related interactions, banning any illegal or harmful content tied to tipping, and outlawing manipulative practices designed to induce unnecessary spending, such as offering cash-back rewards for tipping, artificially inflating tipping totals through creator self-tipping, and other misleading tactics.

    A core focus of the new regulation is enhanced protection for minor users, who are considered particularly vulnerable to overspending and manipulation in livestream environments. The new rules implement a tiered system of protections: children under the age of 8 are completely barred from accessing any livestream tipping services, while minors between 8 and 16 years old can only use these services after platforms obtain explicit consent from a legal guardian. For 16- and 17-year-old minors, platforms must either secure guardian approval or verify that the minor has an independent source of income before granting access to tipping features.

  • China launches first AI-powered digital doctor platform for Parkinson’s disease

    China launches first AI-powered digital doctor platform for Parkinson’s disease

    Against the backdrop of China’s rapidly aging population, Parkinson’s disease has grown into a pressing public health challenge that disproportionately affects older adults, creating greater demand for accessible, efficient neurological care services. In response to this unmet need, Beijing’s Xuanwu Hospital affiliated with Capital Medical University has launched the nation’s first artificial intelligence-driven digital doctor platform tailored exclusively for Parkinson’s disease management.

    Developed through a collaboration between the hospital’s leading Parkinson’s research team and AI technology specialists, the platform is rooted in decades of rigorous clinical work and peer-reviewed medical scholarship. It integrates more than 20 years of Xuanwu Hospital’s accumulated clinical research assets, including anonymized patient medical records, longitudinal study findings, clinical outcome reports, public health educational materials, and a vast library of peer-reviewed global Parkinson’s disease literature to train its AI algorithm.

    Chen Biao, director of the hospital’s Parkinson’s disease clinical research and treatment center, explained that the core design goal of the platform is to streamline routine care workflows. The AI system is capable of responding to up to 90 percent of common patient inquiries about Parkinson’s disease, from symptom management basics to lifestyle adjustment guidance. This automation reduces the burden of repetitive consultations on clinical neurologists, freeing up valuable physician time to focus on complex, high-acuity patient cases that require personalized clinical judgment.

    Accessible via personal smartphones, the platform allows patients to submit questions at any time and receive evidence-based, scientifically accurate responses in real time. Importantly, the system is programmed not to issue individualized treatment recommendations, a safeguard designed to ensure that all critical clinical decision-making remains in the hands of licensed medical professionals. In addition to AI-powered Q&A services, the platform also offers seamless direct links to Xuanwu Hospital’s official online portal, enabling patients to book outpatient appointments and arrange prescription refills without unnecessary administrative delays.

    Looking to the future, the development team has outlined plans to expand the platform’s capabilities. Next-stage iterations will integrate data from consumer wearable health devices to support expanded services, including personalized medication reminders, guided remote rehabilitation training, daily care planning, and targeted mental health support. The end goal is to build a continuous, comprehensive long-term care framework that strengthens the partnership between Parkinson’s patients and their care teams, addressing gaps in ongoing disease management for the growing patient population across the country.

  • Another round of US-Iran peace talks may take place in days: report

    Another round of US-Iran peace talks may take place in days: report

    Tensions across the Middle East remain on a knife’s edge as regional mediators work against the clock to organize a second round of peace negotiations between the United States and Iran in the coming days, according to a new report from the Wall Street Journal. Citing anonymous officials familiar with the diplomatic push, the outlet confirmed that the first round of talks, hosted last week by Pakistani authorities in Islamabad, wrapped up without a binding agreement, leaving a fragile two-week ceasefire teetering on collapse.

    Three core disputes have emerged as the primary barriers to a lasting diplomatic breakthrough. The first contentious issue is Iran’s recent demand to collect transit fees for commercial vessels passing through the Strait of Hormuz, a critical global chokepoint that carries roughly 20% of the world’s daily oil trade. The United States insists Iran reopen the waterway to all traffic without any new charges. Second, negotiators remain deadlocked over the future of Iran’s existing stockpile of highly enriched uranium, a material that can be refined to build nuclear weapons if processed to higher purity. Finally, Tehran is pushing hard for the full release of approximately $27 billion in state revenues that have been frozen by international sanctions imposed by Washington and its allies over the past decade.

    Pakistan, which took on the role of neutral host for the inaugural negotiating session, has emerged as the key broker leading efforts to restart talks before the ceasefire expires on April 22. A senior Pakistani government source told the Wall Street Journal that the entire diplomatic effort is focused on one urgent goal: “wrap it up before the deadline” to avert a full resumption of open hostilities between the two long-time adversaries. While the first round failed to deliver a breakthrough, Pakistani officials remain cautiously optimistic that continued engagement can bridge gaps between the two sides. Active bilateral consultations are already underway with both Washington and Tehran to lock in dates for the second round of talks in the near term, according to insiders.

  • Spanish PM calls for a multipolar world in Tsinghua speech

    Spanish PM calls for a multipolar world in Tsinghua speech

    On April 13, 2026, during the second day of his five-day official visit to China — his fourth trip to the country since taking office — Spanish Prime Minister Pedro Sanchez delivered a landmark address to faculty, students and university administrators at Beijing’s Tsinghua University, where he laid out a clear call for global leaders to embrace an emerging multipolar world order and reject outdated, dangerous zero-sum geopolitical thinking.

    Opening his argument with a centuries-old historical lesson, Sanchez drew on the experience of 16th-century Jesuit missionary Matteo Ricci, who arrived in China in 1583 carrying a European-produced world map that placed Europe at the center of the globe and pushed Asia to its geographic periphery. When Chinese cartographers questioned the lopsided framing that placed China on the margins, Ricci redrew the map with the Pacific Ocean at its center, a reworking that Sanchez framed as a timeless lesson for modern geopolitics.

    “Four hundred years have passed, but unfortunately, there are still people who see the world through that original, distorted map,” Sanchez told the Tsinghua audience. “That view is not only wrong, but very dangerous. It traps us in the past and limits our imagination of possibilities.”

    Sanchez emphasized that the current global shift is not a simple transfer of hegemonic power from one bloc to another, but a broad expansion of global multipolarity that touches both geopolitical influence and shared prosperity. Today, he noted, dynamic progress is unfolding simultaneously across regions with distinct cultural traditions and political systems — from China to Africa to Latin America — without requiring validation or permission from any single dominant power.

    “A multipolar world is not an assumption or an ideal, but a new reality. We cannot change it; we can only deny it or embrace it,” Sanchez said, confirming that Spain has made the deliberate choice to embrace this new reality with realism, a sense of shared responsibility, and optimistic hope for the future. He added that if Spain, China and Europe built shared prosperity in past decades, there is no reason the three actors cannot replicate that success in the modern era.

    Acknowledging that differences and healthy competition exist between nations, Sanchez stressed that lasting human progress stems from building common ground rather than deepening existing divides. He outlined that Spain seeks a bilateral relationship with China rooted in unwavering mutual respect: cooperating on shared global priorities whenever possible, competing constructively when necessary, and managing unavoidable differences through deliberate, respectful dialogue.

    To help a multipolar world order function effectively and equitably, Sanchez proposed three core actionable priorities for global leaders. First, he called for a fundamental reshaping of modern multilateralism, advocating for comprehensive United Nations reform that would expand the authority of the UN General Assembly, increase the representativeness of the UN Security Council, and build a more inclusive, democratic global decision-making mechanism.

    Second, Sanchez highlighted the urgent need to build fair, reciprocal global trade relations, expressing hope that China would continue expanding market access to help address existing trade imbalances across global markets. Third, he stressed that major global powers bear a greater responsibility to address shared transnational challenges, including climate change mitigation, global public health, artificial intelligence governance, nuclear nonproliferation and safety, and global poverty eradication. He noted that global investment in these critical areas has fallen by 23% since the start of 2026, a trend that puts all nations at risk.

    Sanchez also underscored the critical role of a unified European Union in maintaining global stability, noting that “Without a united EU, there will be no stable global order, just as without China’s participation, the world cannot achieve true stability and prosperity.”

    Closing his address, Sanchez invoked a recent image of four NASA astronauts observing Earth from outer space: a single, borderless blue planet that is unique and irreplaceable. “Humanity itself is a miracle, the only miracle in the world. Our responsibility is to make this miracle continue through mutual understanding and cooperation,” he said.

  • Iran’s military warns that no Gulf ports will be safe if its own threatened: report

    Iran’s military warns that no Gulf ports will be safe if its own threatened: report

    Tensions in the Persian Gulf region have spiked following a stark public warning from Iran’s military, which has asserted that no ports across the Gulf will be secure if Iran’s own security interests come under threat, according to recent regional media reports. The alert, dated April 13, 2026, comes at a moment of already heightened friction between Iran and Western powers, most notably the United States, with high-stakes diplomatic discussions between Washington and Tehran recently concluding in Pakistan without reaching any breakthrough agreement.

    The warning marks a significant escalation in rhetorical posturing from Iranian military leadership, amid long-running disputes over Iran’s nuclear program, regional military activity, and international sanctions levied against the country. For years, the Gulf has been a flashpoint for global geopolitical competition, as the waterway handles roughly a third of the world’s seaborne oil trade and a substantial share of global liquefied natural gas shipments. Any disruption to shipping or port operations in the region would send shockwaves through global energy markets, with far-reaching economic consequences for consumer and producer nations alike.

    This latest development follows a string of recent diplomatic engagements between US and Iranian representatives held in Pakistan, which ended without a consensus on core sticking points, leaving both nations bracing for the next round of pivotal negotiations. Analysts note that the harsh tone of Iran’s warning is likely intended to deter any potential military action or further economic pressure from the United States and its regional allies, by signaling that Tehran would be willing to disrupt critical infrastructure across the Gulf in the event of an attack on its own territory or core interests.

    Regional and global powers have long monitored military rhetoric from Iran closely, as any escalation in the region threatens to draw in outside actors and spark a wider conflict that would undermine global energy security and regional stability. As of now, no additional details have emerged regarding specific potential responses from the United States or other Gulf nations to Iran’s warning, with the situation remaining fluid ahead of upcoming diplomatic talks.

  • French lawmakers set to push bill criminalising speech on Israel

    French lawmakers set to push bill criminalising speech on Israel

    A deeply divisive bill that would impose sweeping new criminal penalties on a wide range of speech related to Israel is currently moving through France’s national parliament, triggering fierce public backlash and reigniting long-simmering debates over the boundaries of political expression in the country.

    The legislation, scheduled for its first reading in the National Assembly on April 16, has already earned unusual cross-party support, with backing even from far-right political factions. But the broad political consensus behind the bill has not quelled public opposition: more than 500,000 people have signed a public petition demanding the legislation be scrapped, and organized protests against the measure have spread across multiple French cities as critics warn it poses an unprecedented threat to core free speech protections.

    The proposal is the brainchild of sitting French MP Caroline Yadan, a prominent lawmaker who publicly identifies as an “unconditional” supporter of Israel. Yadan represents the 8th constituency for French citizens living overseas, a district where Israeli residents make up a substantial share of the voting electorate, and she has centered her entire political tenure on advancing policies that defend Israeli actions and interests. She has already openly broken with French President Emmanuel Macron over his official recognition of the Palestinian people’s right to statehood, and publicly condemned Macron in October 2024 after the president called for a halt to French weapons deliveries to Israel amid Israel’s ongoing military campaign in Gaza. Yadan, who is Jewish, has defended the bill with an unsubstantiated claim that “For fifteen years, Jews have been killed in France ‘in the name of Gaza.’”

    If enacted, the bill would introduce a series of far-reaching new criminal offenses. It would make it a crime to deny Israel’s right to exist, and explicitly criminalize comparisons between the Israeli state and Nazi Germany — a legal protection that is not extended to France itself. The legislation also expands existing terrorism-related statutes to cover what the text labels “implicit” provocation, broadening the definition of “apology for terrorism” to include the “minimising or trivialising” of terror attacks.

    Under the bill’s first article, anyone found guilty of speech interpreted as justifying or reframing acts designated as terrorism could face up to five years in prison and substantial financial fines. This broad language could even criminalize framing such acts as “resistance,” or providing contextual background that courts deem insufficiently condemnatory. Critics note the new wording would allow courts to treat attempts to explain the political root causes of violence as criminal acts, opening the door to widespread prosecution of dissenting political speech.

    Marc Trevidic, a former French anti-terrorism judge, has issued a sharp public warning about the dangerous implications of the bill’s vague wording. “Implicit provocation to terrorism: do you realize what that means? Becoming a censor of other people’s thoughts, trying to guess what a person really meant,” Trevidic said.

    One high-profile provision expands existing French laws on crimes against humanity, explicitly classifying any comparison between Israel and Nazi Germany as “outrageous trivialization” of the Holocaust, a criminal offense under the new legislation. The bill’s preamble makes its core intent unambiguous: it explicitly states that framing the Israeli state as equivalent to the Nazi regime must be treated as a criminal act, effectively shielding Israel from one of the most politically charged forms of criticism directed at the country’s policies.

    The legislation builds on France’s already strict existing speech regulations, which have criminalized Holocaust denial under the 1990 Gayssot Act for decades. But legal experts and free speech advocates note the new measures go far beyond existing prohibitions, extending criminal liability into a broad swathe of mainstream political expression. As the first parliamentary vote approaches, the clash between the bill’s cross-party backers and mass public opposition has put France’s commitment to free expression under unprecedented national scrutiny.

  • Monster typhoon in the Pacific Ocean is bearing down on group of remote US islands

    Monster typhoon in the Pacific Ocean is bearing down on group of remote US islands

    The strongest tropical cyclone recorded on Earth so far this year, Super Typhoon Sinlaku, is advancing rapidly toward remote U.S. island territories in the Western Pacific, with emergency officials bracing for catastrophic wind damage, widespread flooding, and destructive rainfall as the storm nears landfall. As of Monday, the storm had maintained sustained maximum winds of 173 miles per hour (278 kilometers per hour), placing it well within the super typhoon classification—an intensity category equivalent to a Category 4 or 5 Atlantic hurricane, reserved for the North Pacific’s most powerful systems. The Joint Typhoon Warning Center, which has tracked super typhoons in the region since 1947, projects Sinlaku will make landfall on the Northern Mariana Islands Tuesday, and will retain Category 4 or 5 strength even as it weakens slightly over the coming 48 hours. The storm’s projected path places the islands of Rota, Tinian, and Saipan directly at risk, while Guam, a major U.S. territory that hosts key American military installations, has already been placed under a tropical storm warning, with damaging winds expected to begin impacting the island as early as Monday. U.S. Coast Guard officials first issued high wind and flood warnings for Guam over the weekend, and military leaders have ordered service members to prepare for the storm and shelter in place—an urgent step that comes just two years after Typhoon Mawar knocked out power across Guam for days, causing widespread disruption. Over the weekend, President Donald Trump approved emergency disaster declarations for both Guam and the Northern Mariana Islands, unlocking federal resources to support local emergency response efforts and speed assistance to affected communities after the storm passes. Super typhoons are the highest classification for tropical cyclones that form in the northwestern Pacific, the ocean basin that consistently produces Earth’s most intense storm systems. To qualify as a super typhoon, a cyclone must produce sustained winds of at least 150 mph (240 kph), and more than 300 such storms have been recorded by the Joint Typhoon Warning Center since the naming convention was adopted in 1947. The approaching storm aligns with recent research finding that rising ocean temperatures driven by climate change are supercharging tropical cyclone intensity, increasing the risk of extreme damage when powerful storms make landfall.

    Ruili celebrates annual Water-Splashing Festival with blessings

    Nestled in southwest China’s Yunnan Province within the Dehong Dai and Jingpo Autonomous Prefecture, the border city of Ruili came alive with vibrant color, joyful laughter and age-old tradition over the weekend of April 11, 2026, as it hosted its iconic annual Water-Splashing Festival. The event, a cornerstone of local Dai cultural identity that marks the beginning of the Dai New Year, drew participants from dozens of ethnic communities across the region, turning the city into a sprawling celebration of shared heritage and collective goodwill.

    The festivities kicked off with a grand opening ceremony that placed intangible cultural heritage front and center. Traditional performances from the Dai and De’ang ethnic groups dominated the stage, bringing centuries-old artistic practices to life for attendees. The iconic peacock dance, renowned for its graceful, fluid movements that mimic the elegant bird central to Dai mythology, blended seamlessly with the thunderous, rhythmic elephant-foot drum dance. Every beat of the large carved drums and every fluid gesture of the dancers held deep cultural meaning, captivating onlookers and setting a festive tone for the days of celebration ahead.

    Once the official opening concluded, the celebration spilled out onto the streets and riverbanks of Ruili, particularly along the scenic shoreline of the Ruili River. Equipped with everything from traditional wooden basins to modern water guns, participants of all ages and ethnic backgrounds rushed into the fun, splashing one another with cool, refreshing water as a symbolic gesture of blessing. For generations, this ritual has carried profound meaning: the water is believed to wash away misfortunes and negativity from the past year, clearing the way for good luck, prosperity and health in the coming months.

    Joyful shouts and peals of laughter echoed across the riverbank as crowds sang, danced and joined together in the fun, embodying the spirit of unity that defines the festival. What began as a sacred cultural observance for local ethnic communities has grown into an inclusive event that brings together people from all walks of life, showcasing the rich multicultural tapestry of southwest China and preserving beloved traditions for new generations.
