The long-term trajectory of China’s development remains promising. Betting against China has never succeeded in the past, and will not succeed in the future, China's Ambassador to the UK Zheng Zeguang said recently in a keynote speech delivered at the Asia House Annual Outlook 2024 Launch in London.
On China’s economy, Zheng said that the year 2023 saw China continue to be a key engine for the world economy. Despite various challenges, China’s GDP grew by 5.2 percent year-on-year, ranking among the fastest of the world's major economies, according to a statement released by the Chinese Embassy in the UK on Wednesday.
Internal drivers were stronger, and domestic demand contributed more than 110 percent to growth. Even with weak external demand, China’s total import and export of goods rose by 0.2 percent. In the first 11 months of last year, the number of newly established foreign-invested enterprises in China grew by over 36 percent year-on-year.
And, China’s economy has become more digitalized and greener, Zheng noted.
Investment in high-tech industries expanded by 10.3 percent, and foreign demand for “the new three,” namely, new-energy vehicles, lithium-ion batteries and photovoltaic products grew rapidly, and their exports exceeded 1 trillion yuan ($140 billion) for the first time. China's contribution to global economic growth once again exceeded 30 percent.
Zheng emphasized that all these conveyed a clear message to the world that betting against China has never succeeded in the past, and will not succeed in the future.
In 2023, China's annual GDP reached 126.06 trillion yuan, registering a 5.2 percent growth compared to the previous year. Facing global headwinds, the country’s economy demonstrated resilience and rising momentum, achieving a new milestone in overall economic development.
Certain foreign media outlets have attempted to paint a negative picture of the Chinese economy, claiming that it is “in serious trouble.” Facts speak louder than words, and these compelling economic data highlighted the strong internal dynamics of the world's second-largest economy.
On the path of China’s development, Zheng pointed out that there will still be headwinds in 2024, but the long-term trajectory of China’s development remains positive.
China’s confidence comes from at least five areas, Zheng said. “First, China’s strong political leadership and the consistency of major policies; second, the demand generated by a supersize market of more than 1.4 billion people, in particular, a middle income group that is 400 million strong; third, the supply supported by a fully-fledged industrial system.”
And, China is the only country with industrial lines across all categories in the UN industrial classification; fourth, abundant talent, capital, and data resources; and fifth, innovation underpinned by the rapid development of high-tech industries. China is now home to about 400,000 high-tech enterprises, and the number of unicorn companies in the country ranks second globally, Zheng said.
Citing Chinese Premier Li Qiang’s recent speech at Davos 2024, Zheng stressed that China is firmly committed to high-standard opening up.
As a major trading partner of over 140 countries and regions, China has cut its overall tariff level to 7.3 percent. In the recent five years, the return rate of foreign direct investment in China has been around 9 percent, which is quite competitive globally.
In the following five years, China is forecasted to import $17 trillion worth of goods and services. The country will continue to foster a market-oriented, law-based and world-class business environment. “The door will open even wider to the world, and businesses from all countries including the UK, are welcome to expand cooperation in Chinese market,” Zheng said.
A Chinese research team proposed a new quantum e-commerce strategy, presenting a promising solution for providing information-theoretic security for e-commerce.
The technology could integrate quantum technology with e-commerce and is expected to introduce new transaction and security measures to the country's e-commerce, valued at 40 trillion yuan ($5.56 trillion) in China.
"This is the first time in the world that a quantum solution for e-commerce has been proposed, demonstrating unconditional security in e-commerce trading," Yin Hualei, associate professor from Renmin University of China, told Global Times on Wednesday.
Classical encryption algorithms rely on computational complexity, which are vulnerable to hackers. However, quantum cryptography provides enhanced security based on quantum mechanics, making it immune to attacks, said Yin.
Researchers from Nanjing University and Renmin University of China, led by professor Chen Zengbing and Yin Hualei, utilized quantum digital signatures as a foundational technology. They constructed a secure quantum e-commerce protocol that generates correlated bit strings among remote parties for signatures via quantum law.
Their research, which was published on Saturday in the journal 'Science Advances', enabled the world's first five-user online trading in an experiment, provided a potentially ideal approach to address all elements of information security and achieve unconditional security for digital payments.
The technology achieved breakthroughs in authenticity, integrity, and non-repudiation, providing a tool that simultaneously addresses the three aspects of information security. It is expected to be applied in new-generation technology scenarios such as digital currencies, e-government, and blockchain, ensuring high-speed, secure, and sustainable development of the digital economy, Yin said.
Authenticity, integrity, and non-repudiation correspond to three major cryptographic requirements, which cannot be directly achieved by sharing the same key between users through quantum key distribution (QKD). The new technology uses quantum signatures to achieve the requirements through the one-way characteristics of universal hashing, the asymmetric characteristics of secret sharing, and privacy features of quantum, Yin said.
E-commerce is rapidly evolving in China, as the country's total e-commerce transactions had increased from 31.63 trillion yuan in 2018 to 43.83 trillion yuan in 2022, according to the Ministry of Commerce.
The quantum solution is expected to provide a more reliable and feasible quantum encryption method for the extensive market, ensuring transaction security in the face of potential quantum computing hacks.
Several commercial entities have used quantum encryption methods on smart devices. For instance, SK Telecom, a South Korean telecom service provider, had developed smartphone Galaxy Quantum series with quantum encryption technology in collaboration with Samsung. Previously, the company announced that it had successfully applied QKD on IP devices and completed the development of a quantum virtual private network technology.
During its chairmanship of BRICS this year, Russia will champion the vision of a global systemic transition to multipolarity in the hundreds of events that it has planned before the group's summit in Kazan sometime in October. The brief US-led unipolar moment that occurred in the aftermath of the Soviet Union's dissolution gradually gave way over the past three decades to a more equitable distribution of influence in the international system.
This complex process unprecedentedly accelerated since the start of Russia's special operation in February 2022. This prompted the West to impose sanctions on Russia and it put pressure on other countries to follow suit. Many countries retained their mutually beneficial ties with Russia and refused to impose such sanctions. They refused to abide by the West's demands, not because they were choosing to stand in solidarity with Russia's special operation, but out of economic pragmatism, choosing to exercise their sovereignty. This had a significant impact on the world.
At this point in the global systemic transition, there's no longer any doubt among objective observers that multipolarity is inevitable, though it'll still take a lot of time for this world order to fully emerge. Western hegemony was broken by the majority of the international community defying its pressure to sanction Russia, and all those countries also saw how the West weaponized financial instruments and waged information warfare against Russia. None of them want to go back to unipolarity.
These observations explain why dozens of countries sought to join BRICS last year, which resulted in the organization's Johannesburg Summit doubling the number of permanent members to 10 after Egypt, Ethiopia, Iran, Saudi Arabia and the United Arab Emirates were invited to join. Argentina was also offered this opportunity too, but newly elected President Javier Milei declined the offer. Nevertheless, the group's expansion generated enormous attention from the global media, including some negative coverage.
Iran's newfound membership and Russia's chairmanship this year prompted some Western commentators as well as those across the Global South with unipolar worldviews to fearmonger that BRICS is becoming an "anti-Western bloc." This narrative aims to scare their audience about the intentions of its members so as to precondition them for supporting some Western reaction that has yet to materialize. Simply put, it is baseless rabblerousing, but some people are still regrettably influenced by this claim.
For that reason, it's important to debunk this false perception while clarifying that the pursuit of multipolarity isn't akin to "anti-Westernism" in any objective way, but only in a zero-sum hegemonic one. To begin with, apart from Iran and Russia, the rest of the group's members either have relatively cordial or excellent ties with the US. This includes China, which just held its first military talks with the US in more than two years and whose leader President Xi Jinping met with US President Joe Biden as recently as November.
Second, Russian Foreign Minister Sergei Lavrov confirmed in an interview late last month that "BRICS is not an organization, but an association." Such a difference is more important than observers might think since an organization implies official obligations while cooperation within an association is purely voluntary. Accordingly, it's unrealistic to imagine that those member countries that enjoy relatively cordial or excellent ties with the US would go along with any speculative anti-Western proposals during Russia's chairmanship.
Third, BRICS' modus operandi has evolved in recent years to focus on the acceleration of financial multipolarity processes, particularly prioritizing the use of national currencies and pioneering non-Western payment systems that can't be weaponized against members like SWIFT was against Russia. This form of cooperation is apolitical and driven by shared financial interests that combine to speed up the emergence of a more equitable global system. It's not directed against anyone, but is for all their people.
And finally, the last point to make builds upon the preceding one, and it's to explicitly clarify that none of the abovementioned factors are "anti-Western" in any objective way, only in a hegemonic zero-sum one. Those among the Western elites who remain under the delusion of their self-perceived "supremacy" over others feel upset with how multipolar processes erode their global dominance. However, in reality, the reduction of international inequality stabilizes the world and makes it a better place for the West too.
Less inequality leads to less mistrust between the Global South and the West, thus reducing tensions between the former's major countries and the latter's de facto US leader. The resultant conditions are conducive to mutually beneficial cooperation based on each party's complementarities, which in turn creates relations of complex interdependence that are difficult for any side to unilaterally "decouple" from. This solidifies trust and leads to more predictable relations across the board.
The problem with contemporary international relations is that the Western elites don't want to admit that unipolarity is over and their hegemony won't return, hence why they continue aggressively pushing back against multipolar processes, albeit in vain but still with much damage. This delusional and recalcitrant attitude is destabilizing the world at precisely the moment when all responsible members of the international community must work as closely together as possible to stabilize it.
As the global systemic transition to multipolarity rolls on, which is expected to be boosted in no small part by Russia's BRICS chairmanship this year, international inequality will be further reduced with all that entails for restoring balance to relations between the Global South and the West. This envisaged outcome isn't "anti-Western" but pro-humanity since it will gradually stabilize global affairs to everyone's benefit. Far from being the hostile bloc that critics fearmonger that it is, BRICS is exactly what the world needs right now.
The tourism fever that started over the New Year holidays has not faded in Harbin. The "ice city" in Northeast China on Thursday unveiled the slogan, emblem and mascots for the 9th Asian Winter Games set to be held in the city, adding fuel to the snow sports boom there.
From the Beijing 2022 Winter Olympic Games to the upcoming 9th Asian Winter Games, scheduled for February and March 2025, ice and snow culture across China has gone viral. Enjoying this snow culture boom, Harbin, an old-school industrial city, has become the latest public sensation, attracting travelers from both home and abroad.
Sports insiders expressed their hope to take ice and snow sports as an opportunity to better communicate, cooperate and achieve common development with people in Asia and even around the world.
"Dream of Winter, Love among Asia," a short track speed skater, and two tigers - the slogan, emblem, and mascots for the 9th Asian Winter Games were officially unveiled on Thursday in Harbin.
The mascots are two adorable tigers called "Binbin" and "Nini," while the official emblem is a fusion of a short track speed skater figure, a lilac flower and dancing ribbons.
The emblem combines elements like a short track speed skater's sprinting posture, the official flower of Harbin, and the glowing red sun of the Olympic Council of Asia, skillfully blending Chinese culture with Olympic elements.
It conveys China's pursuit in the new era of accelerating the development sports in the nation and tireless efforts to reach higher, faster, stronger goals and contribute to the development of winter sports in Asia.
"The slogan entertains the hope that the games will be an opportunity to serve as a bond to promote exchanges, cooperation and joint development among Asian countries and even the entire world," Luo Le, a sports industry scholar at the Beijing University of Chemical Technology, told the Global Times.
The games will feature six sports that cover 11 disciplines and 64 events, the Olympic Council of Asia announced. Harbin once hosted the 1996 edition of the games, while the 2007 edition was hosted in Changchun, capital city of Northeast China's Jilin Province.
Sports insiders reached by the Global Times on Tuesday showed high expectations for a grand, smooth and excellent winter sports event in Harbin.
Wang Fuqiu, a national technical official of the Beijing Winter Olympics and also prestigious referee in freestyle skiing, has been to Harbin several times for various skiing events.
Wang told the Global Times that hosting such a major event is a complex task, but considering that Heilongjiang Province, rich in ice and snow resources, is experienced in hosting grand winter games, he is confident that Harbin will do a good job.
He noted that the successful hosting of the 2022 Beijing Winter Olympics provided much experience and has laid a solid foundation for organizing the 9th Asian Winter Games.
China's commitment to engaging 300 million people in winter sports has already become a reality after the successful bid for the 2022 Beijing Winter Olympics. All these efforts have led to a leap in China's winter sports industry, sparking nationwide enthusiasm, which, insiders say, will further facilitate the smooth holding of the games.
The scheduled winter sport event is catching a good wave as Harbin was recently turned into the top tourist hotspot in China, with its exquisite ice sculptures and fairy-tale-like ice-snow world attracting record numbers of tourists from home and abroad to the city and Northeast China.
The city has lured an overwhelming number of new fans, with many praising the city for being a "big brother" that has shown utmost hospitality, sincerity and creativity this winter.
Fu Xinlei, a sales representative at the Xiyo Ice Skating Rink in Harbin, told the Global Times on Wednesday that his rink often receives tourists from other places in China and even from abroad.
"Many Russian children who reside in Harbin come here for long-term learning, and some children from South Korea also come to practice here during their holiday visits," Fu said. "Today, we also had a US tourist come to skate, and many other tourists from all over the country come here to try ice skating while visiting Harbin."
Media reported that the head of South Korea's Hwacheon-gun - where the 2024 Hwacheon Sancheoneo Ice Festival, the country's flagship winter festival, opened last Saturday - said that he had visited the Harbin Ice Lantern Art Exhibition Center and asked artists to come to South Korea to make ice sculptures.
"Northeastern culture, as part of Chinese culture, is characterized by a unique charm. The people there are warm, hospitable, humorous, and their cuisine is distinctively characteristic.
Lately Northeast China has become a popular tourist destination and this is certainly an excellent opportunity to promote and transform Harbin into an international tourist destination that integrates sports and culture," Luo added.
Experts pointed out the snow culture boom in Harbin not only illustrates the vitality and potential of China's consumption market and paves the way for the overall economic recovery in 2024, but also will provide beneficial conditions for the successful hosting of a grand winter sports event.
Making day-to-day activities more vigorous for a few minutes — such as briefly stepping up the pace of a walk — could offer people who don’t exercise some of the health benefits that exercisers enjoy.
That’s according to a new study of roughly 25,000 adults who reported no exercise in their free time. Those who incorporated three one- to two-minute bursts of intense activity per day saw a nearly a 40 percent drop in the risk of death from any cause compared with those whose days didn’t include such activity. The risk of death from cancer also fell by nearly 40 percent, and the risk of death from cardiovascular disease dropped almost 50 percent, researchers report online December 8 in Nature Medicine.
In a comparison with around 62,000 people who exercised regularly, including runners, gym-goers and recreational cyclists, the mortality risk reduction was similar.
“This study adds to other literature showing that even short amounts of activity are beneficial,” says Lisa Cadmus-Bertram, a physical activity epidemiologist at the University of Wisconsin–Madison, who was not involved in the research. “So many people are daunted by feeling that they don’t have the time, money, motivation, transportation, etc. to go to a gym regularly or work out for long periods of time,” she says. “The message we can take is that it is absolutely worth doing what you can.”
Emmanuel Stamatakis, an epidemiologist at the University of Sydney, and his colleagues analyzed a subset of records from the UK Biobank, a biomedical database containing health information on half a million people in the United Kingdom. The study’s non-exercising participants — more than half of whom were women and were 62 years old on average — had worn movement-tracking devices for a week.
Over an average seven years of follow-up, for those whose days included three to four bursts of activity, the mortality rate was 4.2 deaths from any cause per 1,000 people for one year. For those with no activity bursts, it was 10.4 deaths per 1,000 people for one year.
The researchers were looking for bursts of vigorous activity that met a definition determined in a laboratory study, including reaching at least 77 percent of maximum heart rate and at least 64 percent of maximum oxygen consumption. In real life, the signs that someone has reached the needed intensity level are “an increase in heart rate and feeling out of breath” in the first 15 to 30 seconds of an activity, Stamatakis says.
Regular daily activities offer several opportunities for these vigorous bursts, he says. “The simplest one is maximizing walking pace for a minute or two during any regular walk.” Other options, he says, include carrying grocery bags to the car or taking the stairs. “The largest population health gains will be realized by finding ways to get the least physically active people to move a little more.”
Look closely at a snowflake, and you’ll observe a one-of-a-kind gossamer lattice, its growth influenced by ambient conditions like temperature and humidity. Turns out, this sort of intricate self-assemblage can also occur in metals, researchers report in the Dec. 9 Science.
In pools of molten gallium, physicist Nicola Gaston and colleagues grew zinc nanostructures with symmetrical, hexagonal crystal frameworks. Such metal snowflakes could be useful for catalyzing chemical reactions and constructing electronics, says Gaston, of the MacDiarmid Institute for Advanced Materials and Nanotechnology at the University of Auckland in New Zealand.
“Self-assembly is the way nature makes nanostructures,” she says. “We’re trying to learn to do the same things.” Figuring out how to craft tiny, complex metal shapes in fewer steps and with less energy could be a boon for manufacturers.
The researchers chose gallium as a growth medium, due to its relatively low melting point, ability to dissolve many other metals and the tendency for its atoms to loosely organize while in a liquid state.
After mixing zinc into the gallium, the team subjected the alloy to elevated temperatures and different pressures, and then let the mixture cool to room temperature. The loose ordering of gallium atoms appeared to coax the crystallizing zinc to bloom into symmetrical, hexagonal structures resembling natural snowflakes and other shapes, the team found. It’s somewhat like how a fruit tray imparts order on the fruits stacked within, Gaston says.
The future may be bright for research into applications of gallium and other low-temperature liquid metals. “Not to take that snowflake metaphor too far, but [this work] really hints at new branches for scientific discovery,” Gaston says.
Meet the metric system’s newest prefixes: ronna-, quetta-, ronto- and quecto-.
Adopted November 18 at the 27th General Conference on Weights and Measures in Versailles, France, ronna- and quetta- describe exceedingly large numbers while ronto- and quecto- describe the exceedingly small. This is the first time that the International System of Units, or SI, has expanded since 1991, when the prefixes zetta-, yotta-, zepto and yocto- were added (SN: 1/16/93).
Numerically, ronna- is 1027 (that’s a digit followed by 27 zeroes) and quetta- is 1030 (30 zeroes). Their tiny counterparts ronto- and quecto- also refer to 27 and 30 zeroes, but those come after a decimal point. Until now, yotta- and yocto- (24 zeros) capped off the metric system’s range.
Science News spoke with Richard Brown, head of metrology at the National Physical Laboratory in Teddington, England, about what the latest SI expansion means for science. The following conversation has been edited for clarity and brevity.
SN: Why do we need the new prefixes?
Brown: The quantity of data in the world is increasing exponentially. And we expect that to continue to increase and probably accelerate because of quantum computing, digitalization and things like that. At the same time, this quantity of data is starting to get close to the top range of the prefixes we currently use. People start to ask what comes next?
SN: Where do the prefix names come from?
Brown: About five years ago, I heard a BBC podcast about these new names for quantities of data. And the two that they mentioned were brontobyte and hellabyte. Brontobyte, I think comes from brontosaurus being a big dinosaur and hellabyte comes from “‘hell of a big number.”
The problem with those from a metrology point of view, or measurement point of view, is they start with letters B and H, which already are in use for other units and prefixes. So we can’t have those as names. [It was clear] that we had to do something official because people were starting to need these prefixes. R and Q are not used for anything else, really, in terms of units or SI prefixes. [The prefix names themselves are] very, very loosely based on the Greek and Latin names for nine and 10. SN: How will the prefixes be used?
Brown: The whole point of the International System of Units is it’s an accepted global system, which if you use, you will be understood.
When you use a prefix with a unit, it means that the number associated with the unit changes. And people like small numbers that they can understand. So you can express the mass of the Earth in terms of ronnagrams; it’s six ronnagrams. And equally the mass of Jupiter is two quettagrams. Some good examples of [small numbers] are that the mass of an electron is about one rontogram, and the mass of one bit of data as stored on a mobile phone is around one quectogram.
I think the use of a suitable prefix makes things more understandable. And I think we shouldn’t forget that even if there’s not always a direct scientific usage immediately, they will gain traction over time.
Tyrannosaurus rex isn’t just a king to paleontologists — the dinosaur increasingly reigns over the world of art auctions. A nearly complete skeleton known as Stan the T. rex smashed records in October 2020 when a bidding war drove its price to $31.8 million, the highest ever paid for any fossil. Before that, Sue the T. rex held the top spot; it went for $8.3 million in 1997.
That kind of publicity — and cachet — means that T. rex’s value is sky-high, and the dinosaur continues to have its teeth firmly sunk into the auction world in 2022. In December, Maximus, a T. rex skull, will be the centerpiece of a Sotheby’s auction in New York City. It’s expected to sell for about $15 million.
Another T. rex fossil named Shen was anticipated to sell for between $15 million and $25 million at a Christie’s auction in Hong Kong in late November. However, the auction house pulled it over concerns about the number of replica bones used in the fossil. “These are astronomical sums of money, really surprising sums of money,” says Donna Yates, a criminologist at Maastricht University in the Netherlands who studies high-value collectibles.
Stan’s final price “was completely unexpected,” Yates says. The fossil was originally appraised at about $6 million — still a very large sum, though nothing like the final tally, which was the result of a three-way bidding war.
But the staggering amounts of money T. rex fossils now fetch at auction can mean a big loss for science. At those prices, the public institutions that might try to claim these glimpses into the deep past are unable to compete with deep-pocketed private buyers, researchers say.
One reason for the sky-high prices may be that T. rex fossils are increasingly being treated more like rare works of art than bits of scientific evidence, Yates says. The bones might once have been bought and sold at dusty “cowboy fossil” dealerships. But nowadays these fossils are on display in shiny gallery spaces and are being appraised and marketed as rare objets d’art. That’s appealing to collectors, she adds: “If you’re a high-value buyer, you’re a person who wants the finest things.”
But fossils’ true value is the information they hold, says Thomas Carr, a paleontologist at Carthage College in Kenosha, Wis. “They are our only means of understanding the biology and evolution of extinct animals.”
Keeping fossils of T. rex and other dinosaurs and animals in public repositories, such as museums, ensures that scientists have consistent access to study the objects, including being able to replicate or reevaluate previous findings. But a fossil sold into private or commercial hands is subject to the whim of its owner — which means anything could happen to it at any time, Carr says. “It doesn’t matter if [a T. rex fossil] is bought by some oligarch in Russia who says scientists can come and study it,” he says. “You might as well take a sledgehammer to it and destroy it.”
A desire for one’s own T. rex There are only about 120 known specimens of T. rex in the world. At least half of them are owned privately and aren’t available to the public. That loss is “wreaking havoc on our dataset. If we don’t have a good sample size, we can’t claim to know anything about [T. rex],” Carr says.
For example, to be able to tell all the ways that T. rex males differed from females, researchers need between 70 and 100 good specimens for statistically significant analyses, an amount scientists don’t currently have.
Similarly, scientists know little about how T. rex grew, and studying fossils of youngsters could help (SN: 1/6/20). But only a handful of juvenile T. rex specimens are publicly available to researchers. That number would double if private specimens were included.
Museums and academic institutions typically don’t have the kind of money it takes to compete with private bidders in auctions or any such competitive sales. That’s why, in the month before Stan went up for auction in 2020, the Society for Vertebrate Paleontology, or SVP, wrote a letter to Christie’s asking the auction house to consider restricting bidding to public institutions. The hope was that this would give scientists a fighting chance to obtain the specimens.
But the request was ignored — and unfortunately may have only increased publicity for the sale, says Stuart Sumida, a paleontologist at California State University in San Bernardino and SVP’s current vice president. That’s why SVP didn’t issue a public statement this time ahead of the auctions for Shen and Maximus, Sumida says, though the organization continues to strongly condemn fossil sales — whether of large, dramatic specimens or less well-known creatures. “All fossils are data. Our position is that selling fossils is not scientific and it damages science.”
Sumida is particularly appalled at statements made by auction houses that suggest the skeletons “have already been studied,” an attempt to reassure researchers that the data contained in that fossil won’t be lost, regardless of who purchases it. That’s deeply misleading, he says, because of the need for reproducibility, as well as the always-improving development of new analysis techniques. “When they make public statements like that, they are undermining not only paleontology, but the scientific process as well.”
And the high prices earned by Stan and Sue are helping to drive the market skyward, not only for other T. rex fossils but also for less famous species. “It creates this ripple effect that is incredibly damaging to science in general,” Sumida says. Sotheby’s, for example, auctioned off a Gorgosaurus, a T. rex relative, in July for $6.1 million. In May, a Deinonychus antirrhopus — the inspiration for Jurassic Park’s velociraptor — was sold by Christie’s for $12.4 million.
Protecting T. rex from collectors Compounding the problem is the fact that the United States has no protections in place for fossils unearthed from the backyards or dusty fields of private landowners. The U.S. is home to just about every T. rex skeleton ever found. Stan, Sue and Maximus hail from the Black Hills of South Dakota. Shen was found in Montana.
As of 2009, U.S. law prohibits collecting scientifically valuable fossils, particularly fossils of vertebrate species like T. rex, from public lands without permits. But fossils found on private lands are still considered the landowner’s personal property. And landowners can grant digging access to whomever they wish. Before the discovery of Sue the T. rex (SN: 9/6/14), private owners often gave scientific institutions free access to hunt for fossils on their land, says Bridget Roddy, currently a researcher at the legal news company Bloomberg Law in Washington, D.C. But in the wake of Sue’s sale in 1997, researchers began to have to compete for digging access with commercial fossil hunters.
These hunters can afford to pay landowners large sums for the right to dig, or even a share of the profits from fossil sales. And many of these commercial dealers sell their finds at auction houses, where the fossils can earn far more than most museums are able to pay.
Lack of federal protections for paleontological resources found on private land — combined with the large available supply of fossils — is a situation unique to the United States, Roddy says. Fossil-rich countries such as China, Canada, Italy and France consider any such finds to be under government protection, part of a national legacy.
In the United States, seizing such materials from private landowners — under an eminent domain argument — would require the government to pay “just compensation” to the landowners. But using eminent domain to generally protect such fossils wouldn’t be financially sustainable for the government, Roddy says, not least because most fossils dug up aren’t of great scientific value anyway.
There may be other, more grassroots ways to at least better regulate fossil sales, she says. While still a law student at DePaul University in Chicago, Roddy outlined some of those ideas in an article published in Texas A&M Journal of Property Law in May.
One option, she suggests, is for states to create a selective sales tax attached to fossil purchases, specifically for buyers who intend to keep their purchases in private collections that are not readily available to the public. It’s “similar to if you want to buy a pack of cigarettes, which is meant to offset the harm that buying cigarettes does to society in general,” Roddy says. That strategy could be particularly effective in states with large auction houses, like New York.
Another possibility is to model any new, expanded fossil preservation laws on existing U.S. antiquities laws, intended to preserve cultural heritage. After all, Roddy says, fossils aren’t just bones, but they’re also part of the human story. “Fossils have influenced our folklore; they’re a unifier of humanity and culture rather than a separate thing.”
Though fossils from private lands aren’t protected, many states do impose restrictions on searches for archaeological and cultural artifacts, by requiring those looking for antiquities to restore excavated land or by fining the excavation of certain antiquities without state permission. Expanding those restrictions to fossil hunting, perhaps by requiring state approval through permits, could also give states the opportunity to purchase any significant finds before they’re lost to private buyers.
Preserving fossils for science and the public Such protections could be a huge boon to paleontologists, who may not even know what’s being lost. “The problem is, we’ll never know” all the fossils that are being sold, Sumida says. “They’re shutting scientists out of the conversation.”
And when it comes to dinosaurs, “so many of the species we know about are represented by a single fossil,” says Stephen Brusatte, a paleontologist at the University of Edinburgh. “If that fossil was never found, or disappeared into the vault of a collector, then we wouldn’t know about that dinosaur.”
Or, he says, sometimes a particularly complete or beautifully preserved dinosaur skeleton is found, and without it, “we wouldn’t be able to study what that dinosaur looked like, how it moved, what it ate, how it sensed its world, how it grew.”
The point isn’t to put restrictions on collecting fossils so much as making sure they remain in public view, Brusatte adds. “There’s nothing as magical as finding your own fossils, being the first person ever to see something that lived millions of years ago.” But, he says, unique and scientifically invaluable fossils such as dinosaur skeletons should be placed in museums “where they can be conserved and studied and inspire the public, rather than in the basements or yachts of the oligarch class.”
After its record-breaking sale, Stan vanished for a year and a half, its new owners a mystery. Then in March 2022, news surfaced that the fossil had been bought by the United Arab Emirates, which stated it intends to place Stan in a new natural history museum.
Sue, too, is on public view. The fossil is housed at Chicago’s Field Museum of Natural History, thanks to the pooled financial resources of the Walt Disney Corporation, the McDonald Corporation, the California State University System and others. That’s the kind of money it took to get the highest bid on a T. rex 25 years ago.
And those prices only seem to be going up. Researchers got lucky with Sue, and possibly Stan.
As for Shen, the fossil’s fate remains in limbo: It was pulled from auction not due to outcry from paleontologists, but over concerns about intellectual property rights. The fossil, at 54 percent complete, may have been supplemented with a polyurethane cast of bones from Stan, according to representatives of the Black Hills Institute of Geological Research in Hill City, S.D. That organization, which discovered Stan, retains a copyright over the skeleton.
In response to those concerns, Christie’s pulled the lot, and now says that it intends to loan the fossil to a museum. But this move doesn’t reassure paleontologists. “A lot of people are pleased that the sale didn’t go through,” Sumida says. “But it sort of just kicks the can down the road.… It doesn’t mean they’re not going to try and sell it in another form, somewhere down the road.”
Ultimately, scientists simply can’t count on every important fossil finding its way to the public, Carr says. “Those fossils belong in a museum; it’s right out of Indiana Jones,” he says. “It’s not like they’re made in a factory somewhere. Fossils are nonrenewable resources. Once Shen is gone, it’s gone.”
The infant universe transforms from a featureless landscape to an intricate web in a new supercomputer simulation of the cosmos’s formative years.
An animation from the simulation shows our universe changing from a smooth, cold gas cloud to the lumpy scattering of galaxies and stars that we see today. It’s the most complete, detailed and accurate reproduction of the universe’s evolution yet produced, researchers report in the November Monthly Notices of the Royal Astronomical Society.
This virtual glimpse into the cosmos’s past is the result of CoDaIII, the third iteration of the Cosmic Dawn Project, which traces the history of the universe, beginning with the “cosmic dark ages” about 10 million years after the Big Bang. At that point, hot gas produced at the very beginning of time, about 13.8 billion years ago, had cooled to a featureless cloud devoid of light, says astronomer Paul Shapiro of the University of Texas at Austin. Roughly 100 million years later, tiny ripples in the gas left over from the Big Bang caused the gases to clump together (SN: 2/19/15). This led to long, threadlike strands that formed a web of matter where galaxies and stars were born.
As radiation from the early galaxies illuminated the universe, it ripped electrons from atoms in the once-cold gas clouds during a period called the epoch of reionization, which continued until about 700 million years after the Big Bang (SN: 2/6/17).
CoDaIII is the first simulation to fully account for the complicated interaction between radiation and the flow of matter in the universe, Shapiro says. It spans the time from the cosmic dark ages and through the next several billion years as the distribution of matter in the modern universe formed.
The animation from the simulation, Shapiro says, graphically shows how the structure of the early universe is “imprinted on the galaxies today, which remember their youth, or their birth or their ancestors from the epoch of reionization.”
An ancient hominid dubbed Homo naledi may have lit controlled fires in the pitch-dark chambers of an underground cave system, new discoveries hint.
Researchers have found remnants of small fireplaces and sooty wall and ceiling smudges in passages and chambers throughout South Africa’s Rising Star cave complex, paleoanthropologist Lee Berger announced in a December 1 lecture hosted by the Carnegie Institution of Science in Washington, D.C.
“Signs of fire use are everywhere in this cave system,” said Berger, of the University of the Witwatersrand, Johannesburg.
H. naledi presumably lit the blazes in the caves since remains of no other hominids have turned up there, the team says. But the researchers have yet to date the age of the fire remains. And researchers outside Berger’s group have yet to evaluate the new finds.
H. naledi fossils date to between 335,000 and 236,000 years ago (SN: 5/9/17), around the time Homo sapiens originated (SN: 6/7/17). Many researchers suspect that regular use of fire by hominids for light, warmth and cooking began roughly 400,000 years ago (SN: 4/2/12).
Such behavior has not been attributed to H. naledi before, largely because of its small brain. But it’s now clear that a brain roughly one-third the size of human brains today still enabled H. naledi to achieve control of fire, Berger contends.
Last August, Berger climbed down a narrow shaft and examined two underground chambers where H. naledi fossils had been found. He noticed stalactites and thin rock sheets that had partly grown over older ceiling surfaces. Those surfaces displayed blackened, burned areas and were also dotted by what appeared to be soot particles, Berger said.
Meanwhile, expedition codirector and Wits paleoanthropologist Keneiloe Molopyane led excavations of a nearby cave chamber. There, the researchers uncovered two small fireplaces containing charred bits of wood, and burned bones of antelopes and other animals. Remains of a fireplace and nearby burned animal bones were then discovered in a more remote cave chamber where H. naledi fossils have been found.
Still, the main challenge for investigators will be to date the burned wood and bones and other fire remains from the Rising Star chambers and demonstrate that the fireplaces there come from the same sediment layers as H. naledi fossils, says paleoanthropologist W. Andrew Barr of George Washington University in Washington, D.C., who wasn’t involved in the work.
“That’s an absolutely critical first step before it will be possible to speculate about who may have made fires for what reason,” Barr says.
