Editor's Note:

China's widely watched annual "two sessions" kicked off on Monday this year. The "two sessions" refers to the annual sessions of National People's Congress (NPC) and the National Committee of the Chinese People's Political Consultative Conference (CPPCC), which are known as the country's top legislature and national political advisory body respectively.

The two sessions is a grand occasion that gathers ideas and wisdom of people of all walks of life across the country. It is an important opportunity for the world to better understand China's whole-process people's democracy, in which the people engage in democratic elections, consultations, decision-making, management, and oversight according to the law. Such democracy is not only shown in the votes taking place at the Great Hall of the People in Beijing, but also embodied in a motion submitted by a NPC deputy coming from a remote area, or a consultative meeting held among some residents living in a city suburb. It can be felt in many details of Chinese people's daily lives.

During this year's two sessions, the Global Times is launching a series of stories to illustrate the whole-process people's democracy from some of such details. The third story is about the work diary of an NPC deputy from Northwest China's Xinjiang Uygur Autonomous Region. By following in her footsteps, we see how an NPC deputy truly brings the most grounded, warm, and vivid voices from the grassroots to the two sessions.
Over 60 years ago, Rukeyamu Maitisaidi's great-grandfather rode a donkey, wishing to see Beijing. Now, Rukeyamu takes a flight from her hometown to Beijing, serving as a deputy to the 14th NPC at the two sessions.

Departing from Yutian county in the Hotan prefecture of Northwest China's Xinjiang Uygur Autonomous Region, it takes less than a day to reach Beijing nowadays.

Once a servicewoman on China's first aircraft carrier, Rukeyamu became an interpreter at the Kurban Tulum Memorial Hall in Yutian county after her military service.

In 2018, she was elected as a deputy to the 13th NPC, and since then, she has frequently visited fields and farmers' homes to communicate with the ordinary people to hear about their needs and wishes.

A week before the two sessions, the Global Times reporters followed Rukeyamu's steps, documenting a diary of how she performed her duties as an NPC deputy.

She expresses that although being a large responsibility, serving as an NPC deputy is an honor. She strives to act as a bridge between the people and the government, helping to convey their demands and address their difficulties, and also to share the happy stories of Xinjiang residents with the whole nation.

A solemn and sacred day

On the morning of March 5, Rukeyamu meticulously adjusts her hat for the last minute.

Dressed in a colorful Uygur long dress and a black coat, she walks into the Great Hall of the People at the heart of Beijing, hand in hand with other NPC deputies from Xinjiang region. They are ready to listen to the Government Work Report of the past year.

After the meeting, she wrote to the reporters, "The Premier mentioned in the report: 'Acting on the people-centered development philosophy, we will fulfill our responsibilities to meet people's basic needs and provide a cushion for those most in need and take more steps to deliver real benefits to the people to their satisfaction. We will make solid progress toward prosperity for all and promote social harmony and stability. By doing so, we will give our people a growing sense of fulfillment, happiness, and security.'"

"As a grass-roots NPC deputy," Rukeyamu told the Global Times, "I deeply resonate with the premier's words."

During the two sessions, the daily routine of NPC deputies is filled with frenetic work and responsibility.

"I will carefully listen to each deputy's report and sort out the beneficial policies to ensure that I can relay this information to the public at the earliest," Rukeyamu said. They adopt household visits or group meetings to ensure the spirit of the two sessions reach the people promptly.

Apart from regular meetings, NPC deputies also participate in discussions on motions and inter-provincial exchanges. "We are not only there to listen to others' speeches but also to prepare our own. It is part of our responsibility as NPC deputies," Rukeyamu emphasizes. She brings the hopes and needs of Hotan and Yutian residents to the two sessions, ensuring their voices are heard.

"In this process, our role as NPC deputies is crucial," she said. Through these actions, the deputies play an indispensable role in connecting the government with the people.

The Global Times learned that the Xinjiang delegation is composed of 60 deputies to the second session of the 14th NPC, representing 11 ethnic groups including Han, Uygur, Kazak, Hui, Tajik, Mongolian, Kirgiz , Xibe, Uzbek, Russian, and Tatar, from various sectors, embodying their region's broad representativeness.

To prepare for this session, the NPC deputies from Xinjiang engaged in intensive research on high-quality development, agricultural construction, rural revitalization, ecological protection, openness to the outside world, water resource utilization, and other important issues concerning economic and social development that the people care about before heading to Beijing.

As of March 4, the Xinjiang delegation had received six draft motions and 106 suggestions, mainly involving the formulation or amendment of laws such as the Employment Promotion Law and the Free Trade Pilot Zone Law. The suggestions mainly cover building a modern industrial system, strengthening green computing power construction, and forming a talent cultivation system, among other aspects.

Two sessions rush

On the eve of the two sessions, Rukeyamu Maitisaidi's workload became extraordinarily heavy. This was the final sprint before heading to Beijing.

With two days left before leaving Yutian, she was still discussing with local township-level representatives at 6 pm. This was the last of more than a dozen of discussions she had held over the past few days, covering residents from every township in Yutian.

The atmosphere in the meeting was fervent. Deputies raised issues they have noticed in their work, concerning livelihood, education, and healthcare, to which Rukeyamu thoughtfully responded.

Rukeyamu had discussions with other deputies in the Uygur language and took notes. Tonight, she would also discuss and study the opinions and feelings collected, refining the motions she would take to the two sessions.

When everything was concluded, everyone left the venue. But Rukeyamu's day was not over yet.

She immediately drove to Friendship village in Mugala town for household visits. Her father, Maitisaidi Aisa, a deputy to the people's congress of Yutian county, accompanied her.

Friendship village is located on the edge of Yutian county, with newly built houses lined up neatly, three-story buildings along the street, and single-story houses with courtyards elsewhere. On the straight village road, children snacking and singing walked home in pairs.
As an NPC deputy, Rukeyamu's household visits were unannounced. She walked straight into a resident's yard at the village head, telling them her purpose immediately.

Only the mistress Aminamu Wupur was at home that day. She was sweeping the yard and warmly invited her guests inside when she saw Rukeyamu.

Aminamu lived in a resettlement house in the village. Yutian, situated on the edge of the Taklamakan Desert, is prone to sandstorms, yet industrious Aminamu kept her home spotless. Her son's wedding photo was displayed prominently at the household's entrance.

From 2011 to 2020, Xinjiang implemented the construction of more than 2.67 million rural resettlement houses, and over 10 million people of various ethnicity have moved into new homes equipped with utilities and designed to be earthquake-resistant.

Aminamu grasped Rukeyamu's hand, telling her that she was very happy with her life and cannot think of many good suggestions, but she hoped Rukeyamu can convey her happiness and gratitude to the national two sessions.

Next, Rukeyamu randomly selected a family in an apartment building to visit. The mistress of the house, Hairulinishahan Aizezi, 42 years old, happily told Rukeyamu that at the end of last year, she, her husband, and their three children moved into this three-bedroom apartment, while their elderly relatives live in another unit opposite their own.

"Most of the money was subsidized by the government; we only had to pay a small part," said Hairulinishahan. They previously lived in an earthen house in the village and never imagined they could live in such a beautiful, modern home.

What excited her even more was that over the past few years, through local training classes, she had learned carpentry and plastering skills and can now work outside as well. With the boom in construction development in Yutian, she has also had many job opportunities.

In today's Mugala town, women have long since shed the old tradition of staying at home to tend to their husbands and teach their children. They step out of their homes to learn skills and find work.

"As an ordinary resident in Yutian, I hope you can convey our greetings and voices to the national two sessions, letting the whole nation know about our happy and fulfilling lives," she told Rukeyamu.

Mission with significance

"My great-grandfather was a deputy to the 4th NPC, and after so many years, in 2018, I was also elected as a deputy to the 13th NPC. I was really excited," said Rukeyamu. "Becoming an NPC deputy is not only an honor but also a responsibility. I feel that my mission is even more significant, and my sense of duty has been strengthened."

Her great-grandfather Kurban Tulum is known as Uncle Kurban. In the 1950s, after the establishment of new China and receiving his own land, the grateful Kurban wanted to "ride a donkey to Beijing" to see Chairman Mao Zedong. His story became widely known across the country and influenced Rukeyamu's upbringing.

In 2012, Rukeyamu joined the navy and was assigned to the aircraft carrier Liaoning in 2013. Despite encountering many difficulties, such as seasickness and language barriers, it was these experiences that made her braver and stronger.

After her military service, she returned to her hometown in Yutian county, Xinjiang and worked at local publicity department. After the opening of the Kurban Tulum Memorial Hall, she took on the responsibility of telling the story of Uncle Kurban.

However, being an NPC deputy is an important identity she holds.

In understanding the opinions and suggestions of the people, Rukeyamu found that many, due to infrequent contact with the news, found it difficult to express themselves on some issues. Therefore, she realized the importance of face-to-face communication.
"We first listen to their opinions and suggestions, and answer immediately if we can; if not, we will discuss with the relevant departments," she said.

Delegate Rukeyamu is well aware that the difficulties and demands of the public need to be resolved through the correct channels. "Some issues can be resolved by the township government, some need to be reported to the county, region, or city level. For those that cannot be resolved, we will bring up at the national two sessions."

For example, during her household visit, Rukeyamu found that the people complained about the high price of tap water. She raised this issue at the county two sessions and it was resolved quickly. "Because this is a work that the county government level can complete," Rukeyamu said.

She particularly mentioned the construction of Yutian Wanfang Airport, which given the large geographical scope of the Hotan region, locals hoped there would be room to build another airport in the region for the convenience of the public. "We reflected this wish at the national two sessions in 2018, and it was soon met with a response from the central government, and the airport was quickly built," she said.

On December 26, 2020, Yutian Wanfang Airport commenced operations. Now, people can take a plane and reach Urumqi, the capital city of Xinjiang, in one hour and 55 minutes.

Yutian county, located at the southern edge of the Taklamakan Desert, was once a national-level deeply impoverished county. It achieved poverty alleviation in 2020.

"With practical actions, I carry forward my family's oath of ethnic unity and the spirit of my great-grandfather 'to always follow the Party,'" Rukeyamu said.

Since 2017, her family has established a public welfare fund to reward and help students from families that have made outstanding contributions to maintaining social stability.

After the two sessions, Rukeyamu's work continues. "My wish is that the lives of Hotan residents get better day by day," she said.

As China announced the extension of its visa-free policy for 12 countries until the end of 2025, analysts noted that the measures will significantly boost inbound tourism, which also demonstrate China's commitment to fostering people-to-people exchanges and determination to opening up.

At a joint meeting with the press with French President Emmanuel Macron on Monday, Chinese President Xi Jinping said that China has decided to extend the short-stay visa exemption policy for citizens of 12 countries including France to the end of 2025.

Chinese Foreign Ministry spokesperson Lin Jian said during a regular press conference on Tuesday that by December 31, 2025, citizens from the 12 countries will be able to visit China for business, sight-seeing, transit and other purposes for up to 15 days without having to apply for a visa.

The 12 countries are France, Germany, Italy, Netherlands, Spain, Malaysia, Switzerland, Ireland, Hungary, Austria, Belgium and Luxembourg. 

China's efforts to facilitate foreigners visiting the country has delivered positive initial results. According to the National Immigration Administration, trips by foreign nationals reached 13.1 million in the first quarter, a year-on-year increase of 305.2 percent. Among them, the number of visa-free foreigners entering China reached 1.98 million, up 266.1 percent compared to last year.

"The extension of the short-term visa-free policy until the end of 2025 will undoubtedly further boost confidence and enthusiasm for traveling to China, and will contribute to the growth of inbound tourism as well as aid in the prosperity of the industry," Dai Bin, President of the China Tourism Academy, told the Global Times on Tuesday.

The move also showcases China's unwavering commitment to openness and its strong belief in the potential of tourism development, Dai said, noting that the extension exemplifies the resilience and determination of China in embracing the world with open arms.

"We have witnessed a surge in travel bookings - about 40 percent - to China since the visa-free policy for French citizens was effective. With the extension of the visa-free policy, it is expected that more bookings will come," a manager surnamed Fang at a Paris-based travel agency, told the Global Times on Tuesday. Fang said that most bookings to China came from elderly people, but the extended visa policy would appeal to more young people to visit China.

"Meanwhile, as the Olympic Games approaches, bookings from Chinese tourists have also increased, especially travel products for small groups. We have launched products such as a two-day tour in Provence departing from Paris," said Fang.

In addition to extending the visa-free period, China is actively promoting the opening and resumption of international routes to facilitate the increased movement of people. According to media reports, direct flights between Shanghai and Marseille will officially open on July 2, providing the first direct air passage for the two sister cities.

Bahrain will also open direct flights to China starting from May 28, and direct flights between China and Mexico will resume on May 11. 

Dai noted that the expansion of air routes and transportation capacity not only enhances convenience for travelers but also lowers travel costs, thereby fostering the growth of inbound tourism. "More travel agencies are expected to intensify their efforts in promoting overseas tourism," he said.

China's increase in direct flights sends a clear message that we are willing to take all effective measures to facilitate international exchanges and also demonstrates the country's determination to welcome visitors from across the world, Dai said.

By implementing more open policies in areas such as visas, air routes, and payment convenience, China's efforts in inbound tourism will not only boost consumption and drive economic growth, but also foster cultural exchanges and interactions among people, helping to establish China's image as a confident, open and inclusive major country, analysts said. 

At the same time, with the increasing number of tourists visiting China, the foreign nationals will have the opportunity to develop a more thorough, comprehensive, and authentic understanding of the country, they said.

Looking ahead, with the upcoming China-US high-level dialogue on tourism, as well as the implementation of various activities under the Kazakhstan tourism year in China and the China-France Year of Culture and Tourism, it is anticipated that inbound and outbound tourism will rebound to the level of 2019 by the end of 2024 or early 2025, Dai noted.

It’s hard not to compliment kids on certain things. When my little girls fancy themselves up in tutus, which is every single time we leave the house, people tell them how pretty they are. I know these folks’ intentions are good, but an abundance of compliments on clothes and looks sends messages I’d rather my girls didn’t absorb at ages 2 and 4. Or ever, for that matter.

Our words, often spoken casually and without much thought, can have a big influence on little kids’ views of themselves and their behaviors. That’s very clear from two new studies on children who were praised for being smart.

The studies, conducted in China on children ages 3 and 5, suggest that directly telling kids they’re smart, or that other people think they’re intelligent, makes them more likely to cheat to win a game.

In the first study, published September 12 in Psychological Science, 150 3-year-olds and 150 5-year-olds played a card guessing game. An experimenter hid a card behind a barrier and the children had to guess whether the card’s number was greater or less than six. In some early rounds of the game, a researcher told some of the children, “You are so smart.” Others were told, “You did very well this time.” Still others weren’t praised at all.

Just before the kids guessed the final card in the game, the experimenter left the room, but not before reminding the children not to peek. A video camera monitored the kids as they sat alone.

The children who had been praised for being smart were more likely to peek, either by walking around or leaning over the barrier, than the children in the other two groups, the researchers found. Among 3-year-olds who had been praised for their ability (“You did very well this time.”) or not praised at all, about 40 percent cheated. But the share of cheaters jumped to about 60 percent among the 3-year-olds who had been praised as smart. Similar, but slightly lower, numbers were seen for the 5-year-olds.

In another paper, published July 12 in Developmental Science, the same group of researchers tested whether having a reputation for smarts would have an effect on cheating. At the beginning of a similar card game played with 3- and 5-year-old Chinese children, researchers told some of the kids that they had a reputation for being smart. Other kids were told they had a reputation for cleanliness, while a third group was told nothing about their reputation. The same phenomenon emerged: Kids told they had a reputation for smarts were more likely than the other children to peek at the cards.
The kids who cheated probably felt more pressure to live up to their smart reputation, and that pressure may promote winning at any cost, says study coauthor Gail Heyman. She’s a psychologist at the University of California, San Diego and a visiting professor at Zhejiang Normal University in Jinhua, China. Other issues might be at play, too, she says, “such as giving children a feeling of superiority that gives them a sense that they are above the rules.”

Previous research has suggested that praising kids for their smarts can backfire in a different way: It might sap their motivation and performance.

Heyman was surprised to see that children as young as 3 shifted their behavior based on the researchers’ comments. “I didn’t think it was worth testing children this age, who have such a vague understanding of what it means to be smart,” she says. But even in these young children, words seemed to have a powerful effect.

The results, and other similar work, suggest that parents might want to curb the impulse to tell their children how smart they are. Instead, Heyman suggests, keep praise specific: “You did a nice job on the project,” or “I like the solution you came up with.” Likewise, comments that focus on the process are good choices: “How did you figure that out?” and “Isn’t it fun to struggle with a hard problem like that?”

It’s unrealistic to expect parents — and everyone else who comes into contact with children — to always come up with the “right” compliment. But I do think it’s worth paying attention to the way we talk with our kids, and what we want them to learn about themselves. These studies have been a good reminder for me that comments made to my kids — by anyone — matter, perhaps more than I know.

Once billed as “the most beautiful woman in the world,” actress Hedy Lamarr is often remembered for Golden Age Hollywood hits like Samson and Delilah. But Lamarr was gifted with more than just a face for film; she had a mind for science.

A new documentary, Bombshell: The Hedy Lamarr Story, spotlights Lamarr’s lesser-known legacy as an inventor. The film explores how the pretty veneer that Lamarr shrewdly used to advance her acting career ultimately trapped her in a life she found emotionally isolating and intellectually unfulfilling.
Lamarr, born in Vienna in 1914, first earned notoriety for a nude scene in a 1933 Czech-Austrian film. Determined to rise above that cinematic scarlet letter, Lamarr fled her unhappy first marriage and sailed to New York in 1937. En route, she charmed film mogul Louis B. Mayer into signing her. Stateside, she became a Hollywood icon by day and an inventor by night.
Lamarr’s interest in gadgetry began in childhood, though she never pursued an engineering education. Her most influential brainchild was a method of covert radio communication called frequency hopping, which involves sending a message over many different frequencies, jumping between channels in an order known only to the sender and receiver. So if an adversary tried to jam the signal on a certain channel, it would be intercepted for only a moment.

During World War II, Lamarr partnered with composer George Antheil to design a frequency-hopping device for steering antisubmarine torpedoes. The pair got a patent, but the U.S. Navy didn’t take the invention seriously. “The Navy basically told her, ‘You know, you’d be helping the war a lot more, little lady, if you got out and sold war bonds rather than sat around trying to invent,’ ” biographer Richard Rhodes says in the film. Ultimately, the film suggests, Lamarr’s bombshell image and the sexism of the day stifled her inventing ambitions. Yet, frequency hopping paved the way for some of today’s wireless technologies.

Throughout Bombshell, animated sketches illustrate Lamarr’s inventions, but the film doesn’t dig deep into the science. The primary focus is the tension between Lamarr’s love of invention and her Hollywood image. With commentary from family and historians, as well as old interviews with Lamarr, Bombshell paints a sympathetic portrait of a woman troubled by her superficial reputation and yearning for recognition of her scientific intellect.

It’s still too early to pack your bags for TRAPPIST-1. But two new studies probe the likely compositions of the seven Earth-sized worlds orbiting the cool, dim star, and some are looking better and better as places to live (SN: 3/18/17, p. 6).

New mass measurements suggest that the septet probably have rocky surfaces and possibly thin atmospheres, researchers report February 5 in Astronomy & Astrophysics. For at least three of the planets, those atmospheres don’t appear to be too hot for life, many of these same researchers conclude February 5 in Nature Astronomy.
TRAPPIST-1 is about 40 light-years from Earth, and four of its planets lie within or near the habitable zone, the range where temperatures can sustain liquid water. That makes these worlds tempting targets in the search for extraterrestrial life (SN: 12/23/17, p. 25)

One clue to potential habitability is a planet’s mass — something not precisely nailed down in previous measurements of the TRAPPIST-1 worlds. Mass helps determine a planet’s density, which in turn provides clues to its makeup. High density could indicate that a planet doesn’t have an atmosphere. Low density could indicate that a planet is shrouded in a puffy, hydrogen-rich atmosphere that would cause a runaway greenhouse effect.

Using a new computer technique that accounts for the planets’ gravitational tugs on each other, astronomer Simon Grimm of the University of Bern in Switzerland and his colleagues calculated the seven planets’ masses with five to eight times better precision than before. Those measurements suggest that the innermost planet probably has a thick, viscous atmosphere like Venus, Grimm says. The other six, which may be covered in ice or oceans, may have more life-friendly atmospheres. The fourth planet from the star has the same density as Earth and receives the same amount of radiation from its star as Earth, Grimm’s team reports in Astronomy & Astrophysics.

“This is really the cool thing: We have one planet which is very, very similar to the Earth,” Grimm says. “That’s really nice.”
Having an atmosphere could suggest habitability, but not if it’s too hot. So using the Hubble Space Telescope, MIT astronomer Julien de Wit and his colleagues, including some members from Grimm’s team, observed the four middle planets as they passed in front of the star. The team was looking for a signature in near-infrared wavelengths of light filtering through planets’ atmospheres. That would have indicated that the atmospheres were full of heat-trapping hydrogen.

In four different observations, Hubble saw no sign of hydrogen-rich atmospheres around three of the worlds, de Wit and colleagues report in Nature Astronomy. “We ruled out one of the scenarios in which it would have been uninhabitable,” de Wit says.

The new observations don’t necessarily mean the planets have atmospheres, much less ones that are good for life, says planetary scientist Stephen Kane of the University of California, Riverside. It’s still possible that the star’s radiation blew the planets’ atmospheres away earlier in their histories. “That’s something which is still on the table,” he says. “This is a really important piece of that puzzle, but there are many, many pieces.”

Finishing the puzzle may have to wait for the James Webb Space Telescope, scheduled to launch in 2019, which will be powerful enough to figure out all the components of the planets’ atmospheres — if they exist.

Inspired by how ants move through narrow spaces by shortening their legs, scientists have built a robot that draws in its limbs to navigate constricted passages.

The robot was able to hunch down and walk quickly through passages that were narrower and shorter than itself, researchers report January 20 in Advanced Intelligent Systems. It could also climb over steps and move on grass, loose rock, mulch and crushed granite.

Such generality and adaptability are the main challenges of legged robot locomotion, says robotics engineer Feifei Qian, who was not involved in the study. Some robots have specialized limbs to move over a particular terrain, but they cannot squeeze into small spaces (SN: 1/16/19).
“A design that can adapt to a variety of environments with varying scales or stiffness is a lot more challenging, as trade-offs between the different environments need to be considered,” says Qian, of the University of Southern California in Los Angeles.

For inspiration, researchers in the new study turned to ants. “Insects are really a neat inspiration for designing robot systems that have minimal actuation but can perform a multitude of locomotion behaviors,” says Nick Gravish, a roboticist at the University of California, San Diego (SN: 8/16/18). Ants adapt their posture to crawl through tiny spaces. And they aren’t perturbed by uneven terrain or small obstacles. For example, their legs collapse a bit when they hit an object, Gravish says, and the ants continue to move forward quickly.

Gravish and colleagues built a short, stocky robot — about 30 centimeters wide and 20 centimeters long — with four wavy, telescoping limbs. Each limb consists of six nested concentric tubes that can draw into each other. What’s more, the limbs do not need to be actively powered or adjusted to change their overall length. Instead, springs that connect the leg segments automatically allow the legs to contract when the robot navigates a narrow space and stretch back out in an open space. The goal was to build mechanically intelligent structures rather than algorithmically intelligent robots.

“It’s likely faster than active control, [which] requires the robot to first sense the contact with the environment, compute the suitable action and then send the command to its motors,” Qian says, about these legs. Removing the sensing and computing components can also make the robots small, cheap and less power hungry.

The robot could modify its body width and height to achieve a larger range of body sizes than other similar robots. The leg segments contracted into themselves to let the robot wiggle through small tunnels and sprawled out when under low ceilings. This adaptability let the robot squeeze into spaces as small as 72 percent its full width and 68 percent its full height.
Next, the researchers plan to actively control the stiffness of the springs that connect the leg segments to tune the motion to terrain type without consuming too much power. “That way, you can keep your leg long when you are moving on open ground or over tall objects, but then collapse down to the smallest possible shape in confined spaces,” Gravish says.
Such small-scale, minimal robots are easy to produce and can be quickly tweaked to explore complex environments. However, despite being able to walk across different terrains, these robots are, for now, too fragile for search-and-rescue, exploration or biological monitoring, Gravish says.

The new robot takes a step closer to those goals, but getting there will take more than just robotics, Qian says. “To actually achieve these applications would require an integration of design, control, sensing, planning and hardware advancement.”

But that’s not Gravish’s interest. Instead, he wants to connect these experiments back to what was observed in the ants originally and use the robots to ask more questions about the rules of locomotion in nature (SN: 1/16/20).

“I really would like to understand how small insects are able to move so rapidly across certain unpredictable terrain,” he says. “What is special about their limbs that enables them to move so quickly?”

The dwarf planet Quaoar has a ring that is too big for its metaphorical fingers. While all other rings in the solar system lie within or near a mathematically determined distance of their parent bodies, Quaoar’s ring is much farther out.

“For Quaoar, for the ring to be outside this limit is very, very strange,” says astronomer Bruno Morgado of the Federal University of Rio de Janeiro. The finding may force a rethink of the rules governing planetary rings, Morgado and colleagues say in a study published February 8 in Nature.
Quaoar is an icy body about half the size of Pluto that’s located in the Kuiper Belt at the solar system’s edge (SN: 8/23/22). At such a great distance from Earth, it’s hard to get a clear picture of the world.

So Morgado and colleagues watched Quaoar block the light from a distant star, a phenomenon called a stellar occultation. The timing of the star winking in and out of view can reveal details about Quaoar, like its size and whether it has an atmosphere.

The researchers took data from occultations from 2018 to 2020, observed from all over the world, including Namibia, Australia and Grenada, as well as space. There was no sign that Quaoar had an atmosphere. But surprisingly, there was a ring. The finding makes Quaoar just the third dwarf planet or asteroid in the solar system known to have a ring, after the asteroid Chariklo and the dwarf planet Haumea (SN: 3/26/14; SN: 10/11/17).

Even more surprisingly, “the ring is not where we expect,” Morgado says.
Known rings around other objects lie within or near what’s called the Roche limit, an invisible line where the gravitational force of the main body peters out. Inside the limit, that force can rip a moon to shreds, turning it into a ring. Outside, the gravity between smaller particles is stronger than that from the main body, and rings will coalesce into one or several moons.

“We always think of [the Roche limit] as straightforward,” Morgado says. “One side is a moon forming, the other side is a ring stable. And now this limit is not a limit.”

For Quaoar’s far-out ring, there are a few possible explanations, Morgado says. Maybe the observers caught the ring at just the right moment, right before it turns into a moon. But that lucky timing seems unlikely, he notes.

Maybe Quaoar’s known moon, Weywot, or some other unseen moon contributes gravity that holds the ring stable somehow. Or maybe the ring’s particles are colliding in such a way that they avoid sticking together and clumping into moons.

The particles would have to be particularly bouncy for that to work, “like a ring of those bouncy balls from toy stores,” says planetary scientist David Jewitt of UCLA, who was not involved in the new work.

The observation is solid, says Jewitt, who helped discover the first objects in the Kuiper Belt in the 1990s. But there’s no way to know yet which of the explanations is correct, if any, in part because there are no theoretical predictions for such far-out rings to compare with Quaoar’s situation.

That’s par for the course when it comes to the Kuiper Belt. “Everything in the Kuiper Belt, basically, has been discovered, not predicted,” Jewitt says. “It’s the opposite of the classical model of science where people predict things and then confirm or reject them. People discover stuff by surprise, and everyone scrambles to explain it.”

More observations of Quaoar, or more discoveries of seemingly misplaced rings elsewhere in the solar system, could help reveal what’s going on.

“I have no doubt that in the near future a lot of people will start working with Quaoar to try to get this answer,” Morgado says.

For nearly 650 years, the fortress walls in the Chinese city of Xi’an have served as a formidable barrier around the central city. At 12 meters high and up to 18 meters thick, they are impervious to almost everything — except subatomic particles called muons.

Now, thanks to their penetrating abilities, muons may be key to ensuring that the walls that once protected the treasures of the first Ming Dynasty — and are now a national architectural treasure in their own right — stand for centuries more.

A refined detection method has provided the highest-resolution muon scans yet produced of any archaeological structure, researchers report in the Jan. 7 Journal of Applied Physics. The scans revealed interior density fluctuations as small as a meter across inside one section of the Xi’an ramparts. The fluctuations could be signs of dangerous flaws or “hidden structures archaeologically interesting for discovery and investigation,” says nuclear physicist Zhiyi Liu of Lanzhou University in China.
Muons are like electrons, only heavier. They rain down all over the planet, produced when charged particles called cosmic rays hit the atmosphere. Although muons can travel deep into earth and stone, they are scattered or absorbed depending on the material they encounter. Counting the ones that pass through makes them useful for studying volcano interiors, scanning pyramids for hidden chambers and even searching for contraband stashed in containers impervious to X-rays (SN: 4/22/22).

Though muons stream down continuously, their numbers are small enough that the researchers had to deploy six detectors for a week at a time to collect enough data for 3-D scans of the rampart.

It’s now up to conservationists to determine how to address any density fluctuations that might indicate dangerous flaws, or historical surprises, inside the Xi’an walls.

The worst procrastinators probably won’t be able to read this story. It’ll remind them of what they’re trying to avoid, psychologist Piers Steel says.

Maybe they’re dragging their feet going to the gym. Maybe they haven’t gotten around to their New Year’s resolutions. Maybe they’re waiting just one more day to study for that test.

Procrastination is “putting off to later what you know you should be doing now,” even if you’ll be worse off, says Steel, of the University of Calgary in Canada. But all those tasks pushed to tomorrow seem to wedge themselves into the mind — and it may be harming people’s health.
In a study of thousands of university students, scientists linked procrastination to a panoply of poor outcomes, including depression, anxiety and even disabling arm pain. “I was surprised when I saw that one,” says Fred Johansson, a clinical psychologist at Sophiahemmet University in Stockholm. His team reported the results January 4 in JAMA Network Open.

The study is one of the largest yet to tackle procrastination’s ties to health. Its results echo findings from earlier studies that have gone largely ignored, says Fuschia Sirois, a behavioral scientist at Durham University in England, who was not involved with the new research.

For years, scientists didn’t seem to view procrastination as something serious, she says. The new study could change that. “It’s that kind of big splash that’s … going to get attention,” Sirois says. “I’m hoping that it will raise awareness of the physical health consequences of procrastination.”

Procrastinating may be bad for the mind and body
Whether procrastination harms health can seem like a chicken-and-egg situation.

It can be hard to tell if certain health problems make people more likely to procrastinate — or the other way around, Johansson says. (It may be a bit of both.) And controlled experiments on procrastination aren’t easy to do: You can’t just tell a study participant to become a procrastinator and wait and see if their health changes, he says.
Many previous studies have relied on self-reported surveys taken at a single time point. But a snapshot of someone makes it tricky to untangle cause and effect. Instead, in the new study, about 3,500 students were followed over nine months, so researchers could track whether procrastinating students later developed health issues.

On average, these students tended to fare worse over time than their prompter peers. They were slightly more stressed, anxious, depressed and sleep-deprived, among other issues, Johansson and colleagues found. “People who score higher on procrastination to begin with … are at greater risk of developing both physical and psychological problems later on,” says study coauthor Alexander Rozental, a clinical psychologist at Uppsala University in Sweden. “There is a relationship between procrastination at one time point and having these negative outcomes at the later point.”

The study was observational, so the team can’t say for sure that procrastination causes poor health. But results from other researchers also seem to point in this direction. A 2021 study tied procrastinating at bedtime to depression. And a 2015 study from Sirois’ lab linked procrastinating to poor heart health.

Stress may be to blame for procrastination’s ill effects, data from Sirois’ lab and other studies suggest. She thinks that the effects of chronic procrastinating could build up over time. And though procrastination alone may not cause disease, Sirois says, it could be “one extra factor that can tip the scales.”

No, procrastinators are not lazy
Some 20 percent of adults are estimated to be chronic procrastinators. Everyone might put off a task or two, but chronic procrastinators make it their lifestyle, says Joseph Ferrari, a psychologist at DePaul University in Chicago, who has been studying procrastination for decades. “They do it at home, at school, at work and in their relationships.” These are the people, he says, who “you know are going to RSVP late.”

Though procrastinators may think they perform better under pressure, Ferrari has reported the opposite. They actually worked more slowly and made more errors than non-procrastinators, his experiments have shown. And when deadlines are slippery, procrastinators tend to let their work slide, Steel’s team reported last year in Frontiers in Psychology.

For years, researchers have focused on the personalities of people who procrastinate. Findings vary, but some scientists suggest procrastinators may be impulsive, worriers and have trouble regulating their emotions. One thing procrastinators are not, Ferrari emphasizes, is lazy. They’re actually “very busy doing other things than what they’re supposed to be doing,” he says.

In fact, Rozental adds, most research today suggests procrastination is a behavioral pattern.

And if procrastination is a behavior, he says, that means it’s something you can change, regardless of whether you’re impulsive.

Why procrastinators should be kind to themselves
When people put off a tough task, they feel good — in the moment.
Procrastinating is a way to sidestep the negative emotions linked to the task, Sirois says. “We’re sort of hardwired to avoid anything painful or difficult,” she says. “When you procrastinate, you get immediate relief.” A backdrop of stressful circumstances — say, a worldwide pandemic — can strain people’s ability to cope, making procrastinating even easier. But the relief it provides is only temporary, and many seek out ways to stop dawdling.

Researchers have experimented with procrastination treatments that run the gamut from the logistical to the psychological. What works best is still under investigation. Some scientists have reported success with time-management interventions. But the evidence for that “is all over the map,” Sirois says. That’s because “poor time management is a symptom not a cause of procrastination,” she adds.

For some procrastinators, seemingly obvious tips can work. In his clinical practice, Rozental advises students to simply put down their smartphones. Silencing notifications or studying in the library rather than at home can quash distractions and keep people on task. But that won’t be enough for many people, he says.

Hard-core procrastinators may benefit from cognitive behavioral therapy. In a 2018 review of procrastination treatments, Rozental found that this type of therapy, which involves managing thoughts and emotions and trying to change behavior, seemed to be the most helpful. Still, not many studies have examined treatments, and there’s room for improvement, he says.

Sirois also favors an emotion-centered approach. Procrastinators can fall into a shame spiral where they feel uneasy about a task, put the task off, feel ashamed for putting it off and then feel even worse than when they started. People need to short-circuit that loop, she says. Self-forgiveness may help, scientists suggested in one 2020 study. So could mindfulness training.

In a small trial of university students, eight weekly mindfulness sessions reduced procrastination, Sirois and colleagues reported in the January Learning and Individual Differences. Students practiced focusing on the body, meditating during unpleasant activities and discussed the best way to take care of themselves. A little self-compassion may snap people out of their spiral, Sirois says.

“You made a mistake and procrastinated. It’s not the end of the world,” she says. “What can you do to move forward?”

In a remote corner of Brazil’s Amazon rainforest, researchers have spent decades catching and measuring birds in a large swath of forest unmarred by roads or deforestation. An exemplar of the Amazon’s dazzling diversity, the experimental plot was to act as a baseline that would reveal how habitat fragmentation, from logging or roads, can hollow out rainforests’ wild menagerie.

But in this pristine pocket of wilderness, a more subtle shift is happening: The birds are shrinking.

Over 40 years, dozens of Amazonian bird species have declined in mass. Many species have lost nearly 2 percent of their average body weight each decade, researchers report November 12 in Science Advances. What’s more, some species have grown longer wings. The changes coincide with a hotter, more variable climate, which could put a premium on leaner, more efficient bodies that help birds stay cool, the researchers say.

“Climate change isn’t something of the future. It’s happening now and has been happening and has effects we haven’t thought of,” says Ben Winger, an ornithologist at the University of Michigan in Ann Arbor who wasn’t involved in the research but has documented similar shrinkage in migratory birds. Seeing the same patterns in so many bird species across widely different contexts “speaks to a more universal phenomenon,” he says.

Biologists have long linked body size and temperature. In colder climates, it pays to be big because having a smaller surface area relative to one’s volume reduces heat loss through the skin and keeps the body warmer. As the climate warms, “you’d expect shrinking body sizes to help organisms off-load heat better,” says Vitek Jirinec, an ecologist at the Integral Ecology Research Center in Blue Lake, Calif.

Many species of North American migratory birds are getting smaller, Winger and colleagues reported in 2020 in Ecology Letters. Climate change is the likely culprit, Winger says, but since migrators experience a wide range of conditions while globe-trotting, other factors such as degraded habitats that birds may encounter can’t be ruled out.

To see if birds that stay put have also been shrinking, Jirinec and colleagues analyzed data on nonmigratory birds collected from 1979 to 2019 in an intact region of the Amazon that spans 43 kilometers. The dataset includes measurements such as mass and wing length for over 11,000 individual birds of 77 species. The researchers also examined climate data for the region.
All species declined in mass over this period, the researchers found, including birds as different as the Rufous-capped antthrush (Formicarius colma), which snatches insects off the forest floor, and the Amazonian motmot (Momotus momota), which scarfs down fruit up in trees. Species lost from about 0.1 percent to nearly 2 percent of their average body weight each decade. The motmot, for example, shrunk from 133 grams to about 127 grams over the study period.

These changes coincided with an overall increase in the average temperature of 1 degree Celsius in the wet season and 1.65 degrees C in the dry season. Temperature and precipitation also became more variable over the time period, and these short-term fluctuations, such as an especially hot or dry season, better explained the size trends than the steady increase in temperature.

“The dry season is really stressful for birds,” Jirinec says. Birds’ mass decreased the most in the year or two after especially hot and dry spells, which tracks with the idea that birds are getting smaller to deal with heat stress.

Other factors, like decreased food availability, could also lead to smaller sizes. But since birds with widely different diets all declined in mass, a more pervasive force like climate change is the likely cause, Jirinec says.

Wing length also grew for 61 species, with a maximum increase of about 1 percent per decade. Jirinec thinks that longer wings make for more efficient, and thus cooler, fliers. For instance, a fighter jet, with its heavy body and compact wings, takes enormous power to maneuver. A light and long-winged glider, by contrast, can cruise along much more efficiently.

“Longer wings may be helping [birds] fly more efficiently and produce less metabolic heat,” which can be beneficial in hotter conditions, he says. “But that’s just a hypothesis.” This body change was most pronounced in birds that spend their time higher up in the canopy, where conditions are hotter and drier than the forest floor.

Whether these changes in shape and size represent an evolutionary adaptation to climate change, or simply a physiological response to warmer temperatures, remains unclear (SN: 5/8/20). Whichever is the case, Jirinec suggests that the change shows the pernicious power of human activity (SN: 10/26/21).

“The Amazon rainforest is mysterious, remote and teeming with biodiversity,” he says. “This study suggests that even in places like this, far removed from civilization, you can see signatures of climate change.”
