The pressure on Apple to reorganize its products structure and find more and stronger business avenues is on, ever since Microsoft has topped Apple about one month ago to become the most valuable public company in the world. The competition between the two major tech titans is expected to persist in the coming two to three years, if not longer.
Now, generative artificial intelligence (AI) is churning the seas and making big waves after OpenAI launched the newest ChatGPT bot "Sora" which is able to make vivid and utterly realistic clips of video streams if fed with descriptive texts. Deemed as the next transformative technology that may be capable to reshape our work and life, AI innovation and development is currently on the top agenda of both Apple and Microsoft.
And on Tuesday, Apple's Chief Operating Officer Jeff Williams affirmed that the company is winding down its decade-old endeavor to build an electric vehicle, abandoning one of the most ambitious projects in the company's history. Many employees working on the EV project reportedly will be shifted to Apple's AI project group. Obviously, AI innovation is a key priority of the company and Apple cannot take it for granted.
AI is presumably the next big thing for the world's corporate giants, as joggling for achieving an AI edge has already started. Microsoft, a major stakeholder of OpenAI, seems to be leading in generative AI development and usage. Microsoft has invested billions of dollars in OpenAI and spent the whole of last year racing to push its AI solutions into every product the company offers, which many watchers claim will enable Microsoft to cash in on what they see as its lead in AI.
Apple does not want to fall behind in AI innovation. Apple CEO Tim Cook told investors earlier this month that it has been working on generative AI and was planning to announce some progress later in 2024. "We've got some things that we're incredibly excited about that we'll be talking about later this year," he said on a call with industry analysts.
The decision to shut down its high-profile EV bid is a bombshell for many, which effectively ended a multibillion-dollar effort named Project Titan which would have vaulted the company into a whole new industry. Apple started working on its EV program about 10 years ago, eyeing on a fully autonomous electric car with voice-guided navigation, but the project stumbled and struggled from the start, causing investors to be increasingly concerned with the eventual birth of a car.
But Apple continues to spend heavily in new technology advances. It spent a total of $113 billion on research and development during the past five years, with an average annual growth rate of 16 percent, one of the highest among major tech companies in the world. For instance, Apple last year launched the popular Vision Pro headset.
But Microsoft has moved from "talking about AI to applying AI at scale," according to its chief executive Satya Nadella. The company's more than $3 trillion market valuation is significantly supported by its lead in AI innovation and its flagship cloud computing product called Azure. In the just concluded quarter ending December, the company netted revenue totaling $62 billion, growing 18 percent from a year earlier. Its profit reached $21.9 billion, up 33 percent. Microsoft's cloud offerings brought in $33.7 billion business, just behind Amazon.
Microsoft vowed to invest tens of billions more in building more data centers for AI and cloud computing. Corporate customers have just started trying Microsoft's Copilot offering, which integrates newest AI tools into its cloud productivity programs including Word, Excel and Teams. The improvements have become widely available at the end of last year and cost about $30 per user per month, which is able to create new streams of revenue for Microsoft.
Years ago, Microsoft trailed in market capitalization as its stock price lacked luster after the company acquired Nokia's mobile phone business, which ultimately failed as it could not compete with smartphone giants like Apple and a slew of Chinese phone makers. But Microsoft again places its focus on software development, cloud computing and AI innovation, which eventually pays off and leads to steadily rising stock prices and becomes a darling at Wall Street.
According to Japanese media, Japanese government sources stated on January 15 that Japan and Australia are discussing potential military cooperation in case of simultaneous contingencies in their nearby regions. They also mentioned increasing the sophistication and frequency of joint drills between the Self-Defense Forces and the Australian military and Tokyo has also asked for Canberra's cooperation in using Australia's vast continent as a testing ground for Japanese missiles that are under development, "apparently with China's growing maritime assertiveness in mind."
This reflects the step-by-step implementation of the Australia-Japan Joint Declaration on Security Cooperation signed by Japanese Prime Minister Fumio Kishida and Australian Prime Minister Anthony Albanese in October 2022. It is also a result of vigorous facilitation and promotion by the US. Japan and Australia are becoming two pawns in the US Indo-Pacific Strategy, or more specifically, in the strategy to contain China. This can be likened to the sharp claws of a feline extending from concealed pads.
Following Washington's instructions and deployment, the two countries are overtly strengthening military interactions and cooperation with the explicit goal of countering China. The impact of this approach on the regional situation is inevitably disruptive and detrimental, poisoning the regional peace environment, intensifying tensions, and exerting significant efforts to push the Asia-Pacific region into security dilemmas or traps.
The revealed development, particularly Japan's intention to conduct long-range missile launch tests in Australia, is indeed noteworthy. Japan lacks strategic depth domestically and does not have the conditions for testing medium to long-range missiles. It also faces the restricts of the constitution. Utilizing Australia's territory for this purpose is undoubtedly advantageous for Japan. Australia is breeding an inexplicable "sense of insecurity" under the malicious instigation and misleading of the US, blindly cooperating with and supporting Japan's dangerous actions instead of taking precautions. This is very regrettable.
If this comes to fruition, it would represent a fundamental and substantive betrayal and breach of the Constitution of Japan. Many peace-loving individuals in the Asia-Pacific region, including a significant number of Japanese citizens, have long been strongly concerned about and vehemently opposed to such actions. Japanese media has described the US-Japan-Australia defense relationship as "changing the rules of the game." However, the development of long-range missiles by Japan goes beyond merely "changing the rules of the game." For countries that have previously suffered from Japanese militaristic aggression, it is more akin to lifting the seal on a demon.
Japan enacted a peace constitution after being defeated in World War II and pursued a principle of "exclusive self-defense," establishing an image of a "peaceful nation" and embarking on a "peaceful path" to help Japan quickly gain recognition and trust from countries affected by World War II and integrate into the international community. The rapid recovery and development of Japan's economy after World War II are closely related to this. However, when Japan deviates from the path of peace, recognition and trust of the international community immediately turn into vigilance and suspicion, further becoming obstacles and restrictions on Japan's development path.
Medium to long-range missiles are undoubtedly significant offensive weapons. In late 2022, Japan passed "three security documents," which clearly stated Japan's commitment to policies such as having "enemy base strike capabilities," including various types of long-range offensive missiles and the "integrated air and missile defense" system used in conjunction with the US military. From this news, it can be seen that Japan is moving forward along the planned route of the new security documents, and ahead of this path lies a huge crisis.
This road is not only full of dangers but also causes great harm to the people and the economy. Japan's defense budget for the fiscal year 2024 will increase by 16.5 percent compared to the previous fiscal year, reaching a historical high. The Asahi Shimbun commented that such a large-scale budget "has completely exceeded its own needs and is in an inflated state." The high defense expenditure will undoubtedly squeeze out more financial resources related to people's livelihoods, negatively impacting the lives of Japanese citizens.
Since the intensification of global geopolitical tensions, Japan has been distorting the concept, turning regional countries' expectations for peace into tacit approval or even support for its military development. Facts have proven that Japan's actions are seriously stimulating the escalation of regional tensions. As victims of Japan's past militaristic aggression, Canberra and the South Pacific countries should in no way contribute to the growth of Japan's military ambitions.
Australia, located in the southern hemisphere, could have been free from the disturbance of geopolitical conflicts. There is absolutely no need to let military weapons from other countries cast a shadow of war over this land. In December of last year, Australian defense minister refused to send warships or aircraft to the US-led Red Sea coalition, citing "our strategic focus is our region." If Australia truly feels responsible for its surrounding region, this should be reflected in actions that maintain peace and reduce the risk of war. And Australia should demonstrate strategic autonomy through practical actions.
China's National Immigration Administration (NIA) officially implements five measures to facilitate foreign nationals coming to China, effective on Thursday, including relaxing visa application requirements and simplifying visa application materials. This move represents that China continues to speed up its opening-up to the outside world.
The sluggish recovery of international flights and Western media's disinformation against China are partly responsible for the slow recovery of foreigners' visits to China, said experts. However, they anticipate a boost in visits to China in the coming year. This increase in tourism not only has the potential to enhance trade and people-to-people exchanges but also allows foreigners to gain firsthand experiences and information in China, thereby dispelling any malicious disinformation propagated by Western media.
Liu Haitao, an official from NIA, announced the measures at a conference held on Thursday. One of these measures include the relaxation of the conditions for foreign nationals to apply for port visas to China. For foreign nationals who urgently need to engage in business cooperation, visit exchanges, investment and other non-diplomatic and non-official activities, if they are unable to obtain a visa overseas in time, they can apply for a port visa to enter China by presenting invitation letters and other relevant supporting documents to the port visa authorities.
Foreign nationals can transit through Beijing Capital Airport and other designated international airports in China without going through immigration procedures for up to 24 hours. This policy applies to nine international airports, including Beijing Capital, Beijing Daxing, Shanghai Pudong, and Xi'an Xianyang.
Travelers with international connecting flights within 24 hours can transit through any of these airports to a third country or region without going through immigration procedures and enjoy visa-free transit, said Liu.
The measures will also allow foreign nationals to apply for visa extensions, replacements, or reissues at the nearest location. Foreign nationals who need to enter and exit China multiple times can apply for reentry visas, as the application process will now be simplified.
For foreign nationals applying for visas, if their accommodation registration records and business licenses can be accessed through information sharing, they are exempt from providing relevant paper documents for verification. For foreign nationals in China applying for short-term family reunion visas, a declaration of kinship by the inviting person can be used instead of proof of kinship.
According to the official, as China's economy continues to recover and improve, and its level of opening-up to the outside world expands, there has been a surge in demand for enhanced immigration management services from both domestic and foreign enterprises and individuals.
In response, the NIA is proactively collaborating with relevant authorities to address key challenges and obstacles pertaining to the entry of foreigners for business, study, and tourism in China.
[The recent new measures] are a game-changer for business, a British national doing business in Shanghai who only gave his name as Barrie told the Global Times on Thursday. "This could open up all kinds of opportunities. I can say from experience that the visa application procedures (even for visiting) had been challenging in the past, this easing of process for foreigners to enter will bring flows of travelers, and workers, and commerce."
Border inspection authorities across China checked a total of 210 million visitors entering the country in 2023, recovering to 62.9 percent of the levels seen in 2019. The number of visitors entering the country will continue to rise in 2024 thanks to the resumption of international flights and cross-border personnel exchanges, said an official from the NIA.
The NIA said the number of new applications and replacements for 'Five-Star Card' that is designated for foreign permanent residents increased significantly. Foreigners with permanent residence permits in China can apply for financial services, including banking, securities, and foreign exchanges, said the administration.
Open up further and wider
The latest measures are in line with China's offering of visa-free policy to six countries last year and Central Economic Work Conference held at the end of last year, signaling efforts should be made to foster new drivers of foreign trade, Miao Lu, secretary general of Center for China and Globalization, a Beijing-based non-governmental think tank, told the Global Times on Thursday.
Last month, China rolled out a one-year visa-free policy to ordinary passport holders from six countries - France, Germany, Italy, the Netherlands, Spain and Malaysia - starting from December 1, 2023.
Charles Loke Chee Kin, a Malaysian who has business ties with China, told the Global Times on Thursday, "I used to fly to China once a month. In the past, I had to apply for a visa every time which requires long processing. Now, with the implementation of the visa-free policy between China and Malaysia, it is really convenient for overseas personnel like us who come to China frequently."
Miao said apart from stimulating trade and tourism, the new policies also aim to promote people-to-people exchanges between China and other countries.
According to experts, there is still significant potential for increasing the number of foreigners visiting China, as the number of visitors entering the country in 2023 only reached 62.9 percent of the pre-pandemic level. Miao suggests that one major factor contributing to this slow recovery is the sluggish rebound of international flights.
By the end of 2023, China's scheduled international passenger flights had returned to 4,782 flights per week, around 62.8 percent of the pre-pandemic level, the Civil Aviation Administration of China said on Monday
The pervasive toxic anti-China rhetoric that prevails in the West has undoubtedly taken a psychological toll on some individuals, instilling fear and apprehension in their minds when considering a visit to China, Zhang Yiwu, a professor of Chinese language and literature from Peking University, told the Global Times on Thursday.
For example, some foreign media have been hyping China's revised Counter-Espionage Law since April 2023. A piece published in the Wall Street Journal in April 2023 said that the law and "China's detention of foreigners" have made businesses worried and spooked people who plan to travel there.
Zhang expressed his concerns over the Western media's distortion and defamation of China's efforts to safeguard its national security. He emphasized that this has hindered meaningful people-to-people exchanges. He highlighted that the latest measures, coupled with China's warm gesture, will effectively convey the message that the country welcomes individuals with legitimate intentions. Zhang believes that firsthand experiences in China will dispel the unfounded negative portrayal perpetuated by biased Western media reports.
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.
Marsupials may have richer social lives than previously thought.
Generally considered loners, the pouched animals have a wide diversity of social relationships that have gone unrecognized, a new analysis published October 26 in Proceedings of the Royal Society B suggests. The findings could have implications for how scientists think about the lifestyles of early mammals.
“These findings are helpful to move us away from a linear thinking that used to exist in some parts of evolutionary theory, that species develop from supposedly simple into more complex forms,” says Dieter Lukas, an evolutionary ecologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, who was not involved with the study.
Mammals run the gamut of social organization systems, ranging from loose, ephemeral interactions like aggregations of jaguars in the South American wetlands to the antlike subterranean societies of naked mole-rats (SN: 10/13/21; SN: 10/20/20).
But marsupials — a subgroup of mammals that give birth to relatively underdeveloped young reared in pouches — have traditionally been considered largely solitary. Some kangaroo species were known to form transient or permanent groups of dozens of individuals. But among marsupials, long-term bonds between males and females were thought rare and there were no known examples of group members cooperating to raise young. Previous work on patterns of mammalian social evolution regarded about 90 percent of examined marsupial species to be solitary.
“If you look at other [studies] about some specific species, you will see [the researchers] tend to assume that the marsupials are solitary,” says Jingyu Qiu, a behavioral ecologist at CNRS in Strasbourg, France.
Sorting social lives Qiu and her colleagues developed a database of field studies that illuminated marsupial social organization, taking into account how populations vary within a species and delving into the evolutionary history of marsupial social lives. The researchers compiled data from 120 studies on 149 populations of 65 marsupial species, categorizing each population as solitary, living in pairs — such as one male and one female — or falling into four kinds of group living, including one male and multiple females (or vice versa), multiple males and females, or single sex groups.
While 19 species, or 31 percent of those studied, appear to go strictly solo, nearly half of the species always live in pairs or groups. The team also found lots of variation within species; 27 of the 65 species — more than 40 percent — fell into multiple social organization classifications. When the researchers looked at this social variation against climatic conditions in Australia, they found that social variability was more common in drier environments with less predictable rainfall. It’s possible that being able to switch between solitary and group living acts as a buffer against resource unpredictability.
The researchers’ focus on social flexibility “highlights that there is nothing simple even about a supposedly solitary species,” Lukas says.
Implications for the earliest mammals Qiu and her colleagues also ran computer analyses comparing the evolutionary relationships of the marsupials with how they form social relationships. This let the team predict the social organization of the earliest marsupials, which split from placental mammals about 160 million years ago. Because modern marsupials have been considered solitary, the marsupial ancestors — and the earliest mammals on the whole — have generally been assumed to be solitary as well.
The team found that solitary was the most likely social category of the ancestral marsupials, a 35 percent probability. But Qiu points out that the varied combinations where pair and group living are possible options make up the other 65 percent. So “it is more likely that the ancestor was also non-solitary,” she says. The findings also give insights into the range of possible lifestyles experienced by the earliest mammals, she says.
But Robert Voss, a mammalogist at the American Museum of Natural History in New York City, questions the analyses’ insights about a potentially social ancestral marsupial. The uncertainty about the solitary alternative, he says, is largely due to the researchers’ benchmarks for what does and what doesn’t constitute social behavior — thresholds that Voss views as too permissive. For example, Voss disagrees with the team’s characterization of opossum social organization.
“Anecdotal observations of [members of the same species] occasionally denning together is not compelling evidence for social behavior,” says Voss. “None of the cited studies suggest that opossums are anything other than solitary.”
Future work, Qiu says, will involve gathering data on a larger subset of mammals outside of marsupials to get a clearer picture of how social traits have evolved among mammals.
