BEIJING, Sept. 1 — China launched its first national science popularization month on Monday, starting a 30-day nationwide carnival of science.
Organized by the China Association for Science and Technology, the activities will spotlight scientific innovation achievements, celebrate the scientific spirit and the legacy of scientists, and make science accessible to the public.
Opening ceremonies were held at the National Communication Center for Science and Technology and the China Science and Technology Museum in Beijing — with more than a hundred related exhibitions and activities planned for September. Among them is a special exhibition on Chinese scientists during the Chinese People’s War of Resistance against Japanese Aggression, to mark the 80th anniversary of the victory of the War of Resistance against Japanese Aggression and the World Anti-Fascist War.
China’s revised Science and Technology Popularization Law, which took effect on December 25, 2024, designated September as the annual national science popularization month.
BEIJING, Sept. 1 — China has wrapped up its 62-day summer travel season, with record highs in both passenger and freight transport, according to China State Railway Group Co., Ltd.
From July 1 to Aug. 31, a total of 943 million passenger trips were made by railway — up 4.7 percent from the same period of 2024 and marking a record high.
Notably, the country’s railways handled 3.48 million trips by foreign passengers during this period, an increase of 23.9 percent year on year, as the country continued efforts to facilitate travel for international visitors.
A total of 702 million tonnes of goods were transported by railways in the 2025 summer travel rush — up 4.8 percent year on year.
The summer travel rush is usually a busy season for the country’s railway system, as college students return home for the summer vacation, while family visits and tourist trips also increase during this period.
To meet surging travel demand — China’s railway operator arranged an average of 11,330 passenger trains per day in this period, an increase of 8 percent compared with a year earlier.
The Taliban has called for international aid as Afghanistan reels from an earthquake that killed more than 800 people and left thousands injured.
Rescuers searched into the night for survivors on Monday after the 6.0 magnitude quake struck on Sunday. Many were trapped under the debris of simple mud and stone homes built into steep valleys.
Rescuers struggled to reach remote areas due to rough mountainous terrain and inclement weather. The worst of the destruction was in Kunar province, which borders Pakistan.
The dead, some of them children, were wrapped in white shrouds by villagers who prayed over their bodies before burying them, while helicopters ferried the wounded to hospitals.
“The rooms and walls collapsed … killing some children and injuring others,” said 22-year-old Zafar Khan Gojar, who was evacuated from Nurgal to Jalalabad along with his brother, whose leg was broken.
The disaster will further stretch the resources of the war-torn nation’s Taliban administration, already grappling with crises ranging from a sharp drop in foreign aid to deportations of hundreds of thousands of Afghans by neighbouring countries.
Sharafat Zaman, spokesperson for the health ministry in Kabul, called for international aid to tackle the devastation wrought by the quake of magnitude 6 that struck around midnight local time, at a depth of 10 km (6 miles).
“We need it because here lots of people lost their lives and houses,” he told Reuters.
The quake killed 812 people in the eastern provinces of Kunar and Nangarhar, administration spokesperson Zabihullah Mujahid said.
Ziaul Haq Mohammadi, a student at Al-Falah University in the eastern city of Jalalabad, was studying in his room at home when the quake struck. He said he tried to stand up but was knocked over by the power of the tremor.

“We spent the whole night in fear and anxiety because at any moment another earthquake could happen,” Mohammadi said.
Rescuers were battling to reach remote mountainous areas cut off from mobile networks along the Pakistani border, where mudbrick homes dotting the slopes collapsed in the quake.
“The area of the earthquake was affected by heavy rain in the last 24-48 hours as well, so the risk of landslides and rock slides is also quite significant – that is why many of the roads are impassable,” Kate Carey, an officer at the UN Office for the coordination of Humanitarian Affairs (UNOCHA), told Reuters.
Rescue teams and authorities are trying to dispose of animal carcasses quickly so as to minimise the risk of contamination to water resources, Carey said.
Casualties could rise as rescue teams access more isolated locations, authorities said.
“All our … teams have been mobilised to accelerate assistance, so that comprehensive and full support can be provided,” said health ministry spokesperson Abdul Maten Qanee, citing efforts in areas from security to food and health.
Reuters Television images showed helicopters ferrying out the affected, while residents helped security forces and medics carry the wounded to ambulances in an area with a long history of earthquakes and floods.
Military rescue teams fanned out across the region, the defence ministry said, with 40 flights carrying away 420 wounded and dead.

The quake razed three villages in Kunar, with substantial damage in many others, authorities said. At least 610 people were killed in Kunar with 12 dead in Nangarhar, they added.
Some villagers sat weeping amid the piled ruins of their homes. Others began laboriously clearing the debris by hand, or carried out the injured on makeshift stretchers.
“This is Mazar Dara in Nurgal district. The entire village has been destroyed,” one victim told reporters. “Children and elders are trapped under the rubble. We need urgent help.“
Another survivor said: “We need ambulances, we need doctors, we need everything to rescue the injured and recover the dead.”
It was Afghanistan’s third major deadly quake since the Taliban took over in 2021 as foreign forces withdrew, triggering a cut to the international funding that formed the bulk of government finances.
Diplomats and aid officials say crises elsewhere in the world, along with donor frustration over the Taliban’s policies towards women, including curbs on those who are aid workers, have spurred the cuts in funding.
Even humanitarian aid, aimed at bypassing political institutions to serve urgent needs, has shrunk to $767m this year, down from $3.8b in 2022.
On Monday, Britain set out emergency funding support for those affected by the recent earthquakes, saying it would ensure that the aid does not go to the South Asian country’s current Taliban administration by channelling it through its partners.
Britain’s 1-million-pound ($1.35-million) assistance will be split between the United Nations Population Fund (UNFPA) and the International Red Cross (IFRC) to deliver critical healthcare and emergency supplies to Afghans in the most affected regions, the government statement said.
“The UK remains committed to the people of Afghanistan, and this emergency funding will help our partners to deliver critical healthcare and emergency supplies to the most hard-hit,” British foreign minister David Lammy said in the statement.
A spokesperson for China’s foreign ministry said it was ready to provide disaster relief assistance “according to Afghanistan’s needs and within its capacity”.
Meanwhile, foreign minister Subrahmanyam Jaishankar of India said it had delivered 1,000 family tents to Kabul and was moving 15 tonnes of food material to Kunar, with more relief material to be sent from India starting on Tuesday.
The US state department’s Bureau of South and Central Asian Affairs posted its condolences on X on Monday for the loss of life in the earthquake, but did not immediately respond when asked if the United States would provide any assistance.
Graham Greene, the prolific Oscar-nominated Canadian First Nations actor and Hollywood trailblazer, has died aged 73 in a Toronto hospital after a long illness.
“He was a great man of morals, ethics and character and will be eternally missed,” Greene’s agent, Michael Greene (no relation), told Deadline. “You are finally free.”
Greene was born in 1952 in Ohsweken, on the Six Nations Reserve in Ontario, Canada. He fell into acting while working as a recording engineer, after a friend persuaded him to read his script. He started on stage, performing in Canadian and English productions in the 1970s, before making his screen debut in 1979 in an episode of the Canadian drama The Great Detective. His first film role was in the 1983 biopic Running Brave.
Greene’s Hollywood breakthrough came when Kevin Costner cast him as real-life Lakota Sioux medicine man Kicking Bird (Ziŋtká Nagwáka) in his Academy Award-winning 1990 western Dances with Wolves. Greene’s performance landed him an Academy Award nomination and launched his Hollywood career, which included roles in Thunderheart (1992), Maverick (1994), Die Hard with a Vengeance (1995), The Green Mile (1999) and The Twilight Saga: New Moon (2009).

More recently, Greene appeared in Taika Waititi’s FX series Reservation Dogs, HBO’s dystopian series The Last Of Us and Taylor Sheridan’s series 1883 and Tulsa King.
Prolific across his career, he worked until the end, with multiple projects yet to be released.
Greene won Grammy, Gemini and Canadian Screen awards across his career and has a star on Canada’s Walk of Fame. In June he received the Canadian governor general’s performing arts award for lifetime achievement.
Reflecting on his career in a 2024 interview for Canada’s Theatre Museum, Greene said: “When I first started out in the business, it was a very strange thing where they’d hand you the script where you had to speak the way they thought native people spoke. And in order to get my foot in the door a little further, I did it. I went along with it for a while … You gotta look stoic. Don’t smile … you gotta grunt a lot.
“I don’t know anybody who behaves like that. Native people have an incredible sense of humour.
“And that’s what I said to Kevin [Costner]. I said, you know, the people in this film [Dances with Wolves], in this village, they have an incredible family, incredible relationship and fun has always been part of that. Fun is 50% of how they live and enjoy things. Family is family, no matter what.”
Greene is survived by his wife of 35 years, Hilary Blackmore, his daughter, Lilly Lazare-Greene, and grandson Tarlo.

US treasury secretary Scott Bessent has said the Federal Reserve is and should be independent but that it had “made a lot of mistakes”, as he defended Donald Trump’s right to fire the central bank governor Lisa Cook.
The president has criticised the Fed and its chair, Jerome Powell, for months for not lowering interest rates. Independent central banks are widely seen as crucial to a stable global financial system. Bessent also rejected the idea that markets were disturbed by the Trump administration’s actions. “S&P’s at a new high and bond yields are fine, so we haven’t seen anything yet,” he said.
Bessent’s comments come as Christine Lagarde, the president of the European Central Bank (ECB), said Trump undermining the independence of the world’s most powerful central bank could pose a “very serious danger” for the world economy.
Trump’s war on Fed is ‘serious danger’ to world economy, says ECB head
Lagarde, who was France’s finance minister until 2011 before leaving to run the International Monetary Fund, said it would be “very difficult” for Trump to take control of Fed decision-making on interest rates, but such a scenario would be highly dangerous.
“If US monetary policy were no longer independent and instead dependent on the dictates of this or that person, then I believe that the effect on the balance of the American economy could – as a result of the effects this would have around the world – be very worrying, because it is the largest economy in the world,” she said, according to remarks reported by Reuters.

Guatemala says it is willing to receive hundreds of deported children from US
Guatemala is ready and willing to receive about 150 unaccompanied children of all ages each week from the US, the country’s president has said, a day after a US federal judge halted the deportation of 10 Guatemalan children.
Those children had already boarded a plane when a court responded to an emergency appeal on Sunday. They were later returned to the custody of the Office of Refugee Resettlement.
On Monday, Guatemala’s president, Bernardo Arévalo, told journalists that his government had been coordinating with the US to receive the unaccompanied minors.

Trump says he will award Rudy Giuliani the Presidential Medal of Freedom
The president said Monday he would award Rudy Giuliani the nation’s highest civilian honour, the Presidential Medal of Freedom, two days after his longtime political ally was seriously injured in a car crash.
The decision places the award on a man once lauded for leading New York after the 11 September 2001 attacks and later sanctioned by courts and disbarred for amplifying false claims about the 2020 US presidential election. Giuliani, the former New York mayor, was also criminally charged in two states; he has denied wrongdoing.

Hundreds of ‘workers over billionaires’ Labor Day rallies take place across US
Hundreds of protests organised as part of the national “workers over billionaires” effort – a mass action calling for the protection of social safety – were held in cities large and small across the country, including New York, Houston, Washington DC and Los Angeles.
As the Labor Day rallies took place, Chicago mayor Brandon Johnson sharply denounced the Trump administration’s threat to deploy federal troops to the city as part of an immigration crackdown.

What else happened today:
For this Labor Day, the Trump administration has draped an enormous banner outside the US labor department with his portrait and the words “American Workers First”. But many labor advocates say Trump has consistently put corporate interests first in his second term as he has taken dozens of actions that hurt workers.
Catching up? Here’s what happened on 31 August 2025.
This as-told-to essay is based on a conversation with Advait Maybhate, a software engineer. The following has been edited for length and clarity. Business Insider has verified his employment and academic history.
When I graduated from the University of Waterloo with my bachelor’s degree in 2023, I had done about a dozen tech internships.
Internships are a big deal at Waterloo, and students usually do six during their time there. I started doing internships before I enrolled and took some gap semesters to squeeze in a couple more stints.
To me, internships meant exploring varied fields, from gaming to fintech. I also got to intern at companies of different scales, from early-stage startups to mature Big Tech companies.
The first summer internship I did at Waterloo was at Google. Interning there was an eye-opening experience. I got to work on Google Search, a product that billions of people, including myself, use every single day.
When I took up the internship, like any freshman, I just thought it would be cool to work at a big company and ship big products. I ended up interning at Google twice, first in the summer of 2019, and then during the following summer in 2020.
During my internships at Google, I learned a lot, particularly about operating as a software engineer on large-scale products. That included learning how to write unit tests and good technical design documents. Big companies are great at that.

That said, I didn’t enjoy the bureaucracy that came with working in a Big Tech company. If you are shipping something on Google Search, you cannot break Google Search. That is just one of the underlying rules.
I understand why things have to be slow at that scale. It’s just that for someone who wants to learn fast and try out different things, it can feel limiting.
Even for my internship projects, it took a few months just for the code to get shipped. Although the projects were technically done, we still had to conduct A/B testing experiments and get sign-offs before the code could be deployed.
Going from Big Tech to startups
That experience eventually set me on the path toward working at startups. I chose to focus on AI because I wanted to be at the edge of what technology can do.
I was initially an AI skeptic. I didn’t buy into the hype of how it could change everything. It was only when I started using AI on a day-to-day basis that I began to appreciate how it could usher in a fundamental shift in the way we work.
It also helps that working on AI is fun and exciting. There are new advancements in space every week, and the frontier of what we can do just keeps going further.
I ended up doing two internships at two AI startups before I graduated. The first one was at Warp, an AI agent platform for developers, and the second one was at Ramp, a fintech startup that uses AI to automate financial operations.
I received full-time offers from both Warp and Ramp and chose to work at Warp. Both were great companies, but I wanted to work at Warp because I wanted to be part of a startup that was in a relatively early stage of development.
Ramp was at a much more mature stage than Warp at the time, and was focused on scaling up. Warp, on the other hand, was still trying to figure things out. On a personal level, I wanted to see how a startup goes through that process. I wanted to grapple with questions like, “How does pricing work? How does the business model work?”
That is harder to see at a mature startup, where all of these things have already been figured out and growth is the priority.
So far, working at Warp for the past two yearshas lived up to my expectations. We ship code every week. I could be working on something on Tuesday, and it gets shipped out on Thursday. I work maybe 60 to 70 hours a week. It’s a very different kind of velocity and cadence than at Big Tech.
In the near term, I want to continue to work on AI because it’s one of the most rapidly expanding areas in tech. Companies like Warp and its competitors, Cursor and Cognition, are all expanding very rapidly.
I am somewhat tempted to launch my own startup, but I think it’s difficult to gain market share in this hyper-competitive space. That’s something I will give serious thought about in the future.

According to a recent study, events geologists use to distinguish transitions between geological chapters in Earth’s story follow a hidden hierarchical pattern, one that could shed light on both past and future tumult.
“Geological time scales may look like tidy timelines in textbooks, but their boundaries tell a much more chaotic story,” says study co-author Andrej Spiridonov, a geologist and paleontologist at Vilnius University in Lithuania.
“Our findings show that what seemed like uneven noise is actually a key to understanding how our planet changes, and how far that change can go,” Spiridonov says.
Related: The Human Epoch Doesn’t Officially Exist. But We Know When It Began.
The history of our planet is full of upheavals, some dramatic enough to trigger whole new blocks of geological time. This includes changes between comparatively short divisions like ages and epochs, as well as much longer units of time like eras and eons.
The asteroid that decimated the dinosaurs 66 million years ago, for example, caused enough overall disruption to help conclude the Mesozoic Era and kick off the Cenozoic. The Cenozoic, which continues today, is further subdivided into three periods and at least seven epochs.

The processes driving these transitions are complicated, yielding variable intervals of relative stability punctuated by apparently unpredictable calamities of different types and magnitudes.
Yet there are signs this may be less capricious than it seems.
The new study focuses on the current Phanerozoic Eon, which dates back around 540 million years and includes the Cenozoic, Mesozoic, and Paleozoic eras. It’s one of Earth’s four eons so far, preceded by the Proterozoic, Archean, and Hadean.

Spiridonov and his colleagues used time divisions established by the International Commission on Stratigraphy, but also analyzed boundaries based on stratigraphic ranges of marine animals and on ancient taxa such as conodonts, ammonoids, graptolites, and calcareous nanoplankton.
The boundaries between time units consistently formed intriguing clusters, they found, separated by lengthy spans of relative calm.
This uneven distribution suggests a multifractal system, or one whose complex dynamics are dictated by a continuous spectrum of exponents.
“The intervals between key events in Earth’s history, from mass extinctions to evolutionary explosions, are not scattered completely evenly,” Spiridonov says. “They follow a multifractal logic that reveals how variability cascades through time.”
The researchers sought to estimate Earth’s ‘outer time scale,’ or the amount of time needed to reveal the breadth of our planet’s natural variability.
Based on their findings, they conclude this span is at least 500 million years.
“If we want to understand the full range of Earth’s behaviours, whether periods of calm or sudden global upheaval, we need geological records that cover at least half a billion years. And ideally, a billion,” Spiridonov says.
Studying shorter time scales may fail to convey the extremes our planet is capable of producing, the researchers warn.
Since all of human history has occurred within just a recent sliver of tranquility, a more robust grasp of Earth’s large-scale patterns would likely be valuable.
To help characterize the distribution of these time units and their boundaries, the researchers developed a new model, which they describe as a “compound multifractal-Poisson process.”
Their analysis points to a structure of stage-defining events nested hierarchically, forming a cascade of clusters within clusters.
“We now have mathematical evidence that Earth system changes are not just irregular,” Spiridonov says. “They are deeply structured and hierarchical.”
Beyond helping us understand what has already happened on Earth over the past 4.5 billion years or so, these findings – along with future research building upon them – could offer invaluable insight about what to expect in the future.
“This has huge implications not only for understanding Earth’s past,” Spiridonov says, “but also for how we model future planetary change.”
The study was published in Earth and Planetary Science Letters.

Using total-body PET imaging to get a better understanding of long COVID disease is the goal of a new project at the University of California, Davis, in collaboration with UC San Francisco. The project is funded by a grant of $3.2 million over four years from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.
The uEXPLORER total-body PET scanner at UC Davis will be used in a new project to look at the underlying causes of long COVID symptoms.
About 1 in 10 COVID-19 survivors develop a range of long COVID symptoms that can last from months to years. How and why these symptoms develop isn’t completely known, but they have been linked to activated immune T cells getting into organs and tissues. Researchers also have linked long COVID to damage to the inner lining of blood vessels. These events can be related, because blood vessels become leaky when T cells are activated nearby, but may also be coincidental because leaky blood vessels allow more immune cells to leave the blood and enter tissues.
Negar Omidvari, assistant project scientist at the UC Davis Department of Biomedical Engineering and principal investigator on the grant, will use total-body positron emission tomography (PET) technology, originally developed by Professors Simon Cherry and Ramsey Badawi at UC Davis, and kinetic modeling to look at both processes simultaneously in patients with long COVID.
PET imaging usually uses short-lived radioactive tracers to measure metabolic activity inside the body. Conventional PET can only look at a single organ or a section of the body at a time. The uEXPLORER PET scanner developed at UC Davis can image the entire body at the same time, giving a much more detailed picture of what is going on in the body.
Omidvari will collaborate with CellSight Technologies Inc. of San Francisco to use a tracer called 18F-AraG, which specifically tags activated T cells. Using dynamic total-body PET imaging and sophisticated modeling, she aims to see how activated T cells collect in different organs at different times, where blood vessel damage is occurring, and whether these processes are related to each other.
“If we can separate the vascular damage from the presence of activated T cells in tissue, we should be able to get a much better picture of what’s going on,” Omidvari said.
The team will also check blood samples for markers for inflammation and immune activation that correlate with PET imaging data.
The study will work with patients from UCSF’s long COVID program (LIINC – Long-term Impact of Infection with Novel Coronavirus) who will be scanned at baseline, four and eight months. People who have fully recovered from COVID-19 and have no remaining symptoms will be scanned as controls.
