60+ launches lined up; new-gen manned launch vehicle & super heavy-lift carrier rocket to debut in 2027, 2030: deputies, political advisors

In another ambitious step toward becoming a strong space power in the world, China will fully kick off the research and development of its Phase-4 lunar research project and planetary exploration project, as well as the development of the Chang'e-7 and Tianwen-2 probes, deputies of the national legislature political advisors from the space sector told the Global Times on Sunday during the ongoing two sessions. 

More than 60 launches are scheduled for the Long March carrier rocket series in 2023, and another major rocket family for commercial spaceflights - the Kuaizhou - will also have a tight schedule with 8-10 launches expected this year, the Global Times has learned from Feng Jiehong, a deputy to the 14th National People's Congress (NPC) and head of Aerospace Sanjiang, a subsidiary of China Aerospace Science and Industry Corporation.

The new-generation manned launch vehicle is set to make its maiden flight by 2027, while the new super heavy-lift carrier rocket - the Long March-9 - will debut around 2030, the Global Times has learned. 

Following the completion of its basic structure assembly, the China Space Station has entered normal operations mode and will welcome onboard the Xuntian space telescope before 2026, a task to be undertaken by a Long March-5B carrier rocket, Rong Yi, chief designer for the Long March-2F launch vehicle and a member of the Chinese People's Political Consultative Conference (CPPCC) National Committee, told the Global Times. 

As for commercial spaceflight in China, market demand has been growing rapidly in recent years. According to an Iresearch survey, China has announced 12 plans for small satellite constellation networks in the next five to 10 years, which will comprise more than 2,200 satellites. They are mainly remote sensing and communication satellites. 

If 8-10 satellites are released each launch, it will take nearly 300 missions to complete the task. 

In addition to the Jielong-3 solid-propellant rocket, the Long March-2C and Long March-11 will undertake international commercial spaceflight missions, Wang Xiaojun, head of the state-owned China Academy of Launch Vehicle Technology, told the Global Times. 

Wang revealed that China is developing a next-generation manned launch vehicle that will meet the long-term strategic need for manned lunar exploration. It will be capable of sending payloads of 70 tons into near-Earth orbit, and is expected to make its maiden flight by 2027.

It will be used to send a lunar surface lander and lunar landing spacecraft to the Lunar Transfer Orbit (LTO) using liquid hydrogen, liquid oxygen and kerosene propellants, capable of carrying payloads of no less than 27 tons to the LTO. 

It will serve as an important strategic support to realize China's manned landing on the moon by 2030. 

Rong disclosed that a new-generation manned spacecraft and a moon lander are being developed. The spacecraft will be able to accommodate three astronauts to the LTO and return them to Earth, while the lander could allow two people to carry out scientific experiments on the lunar surface. 

The Earth-Moon space has become a new territory of manned activities in space for its rich material resources and unique environmental resources, which could become a new pillar of the national economy in the future as well as the "best sample" for studying the origin and evolution of the Earth. 

Yang Mengfei, chief engineer of the Chang'e-5 probe and member of the CPPCC National Committee, proposed at this year's two sessions that China should grasp this opportunity and build Earth-Moon space infrastructure to utilize those resources, which China has already has the ability to do. 

The new model super heavy-lift carrier rocket - the Long March-9 - is also under development. It will be a 10-meter-diameter, three-stage mega rocket with a height of 110 meters, capable of sending payloads of 150 tons into near-Earth orbit, 50 tons into the LTO and 35 tons to the Mars Transfer Orbit. The first flight of the Long March-9 vehicle can be expected around 2030.

In this year's government report delivered by Premier Li Keqiang at the first session of the 14th NPC on Sunday, Li elaborated on the fruitful achievements made in scientific and technological innovation in the past years including in areas of manned spaceflight, lunar and Martian exploration, and satellite navigation. 

Chinese researchers make another new discovery from data acquired by Zhurong Mars rover

Chinese researchers have made another new discovery while studying data acquired from China's Zhurong Mars rover, confirming that wind and sand activities on the Martian surface have recorded changes in the ancient Martian environment. The discovery, scientists said, may shed light on predicting future climate changes on Earth.

The research findings have been published online in the science journal Nature on Thursday, the China Lunar Exploration Project (CLEP) said on its official WeChat account on Monday. 

Among planets in the solar system, Mars is considered to be the most similar to Earth. Scientists believe that the current state and evolutionary history of Mars may represent the "future of Earth." Therefore, the study of Martian climate evolution has long been a topic of great interest, and wind and sand activity have shaped the extensive distribution of sand dune features on the Martian surface.

"Wind and sand activities can be said to have recorded the characteristics of the late evolution and recent climate environment of Mars, as well as the process of its climate change. However, due to the lack of detailed and systematic scientific observations in situ and at close range, we still know very little about the process," said Li Chunlai, a research fellow at the National Astronomical Observatory of China, Chinese Academy of Sciences.

In order to address this scientific question, researchers used high-resolution cameras, navigation terrain cameras and multispectral cameras among others on the Zhurong rover to conduct joint remote sensing and close-range investigations in the landing area on the Red Planet. 

Through in-depth analysis, the researchers discovered significant evidence of changes in the wind regime in the Zhurong landing area. 

The evidence shows good consistency with the ice-dust cover layers found in high latitudes on Mars, indicating that the Zhurong landing area may have experienced two major climate stages marked by changes in wind direction, with a nearly 70-degree shift from northeast to northwest. 

The wind-sand accumulation transformed from crescent-shaped bright dunes to longitudinal dark sand ridges.

This climate change occurred approximately 400,000 years ago, at the end of the last ice age on Mars, scientists said, according to the CLEP. It is believed to have been caused by variations in the axial tilt of Mars, which resulted in a global climate transition from an ice age to an interglacial period.

Li said that this research has contributed to our understanding of the ancient climate history of Mars, providing a new perspective for the study of Mars' ancient climate and important constraints for global climate simulations on Mars. It may even provide insights for the future climate evolution of Earth, Li said. 

China's health authority launches one-year anti-corruption campaign

Together with other nine departments, the National Health Commission (NHC) has launched a one-year campaign to crack down on corruption in the healthcare sector across the country, focusing on "key few" and key positions in the pharmaceutical industry to ensure high-quality development of the medical and healthcare sector, the NHC announced on Tuesday.

Since China started the sweeping anti-corruption drive in the public health sector in mid-July, at least 176 Party secretaries or heads of hospitals had been put under investigation as of Saturday, according to media estimates.

Strengthening the anti-corruption work in the healthcare field is an important content of promoting the high-quality development of the pharmaceutical industry, and an important part of improving the construction of the pharmaceutical governance system.

In recent years, some people in key positions have been guilty of accepting kickbacks, bribery and profiteering, among other crimes, thereby seriously diluting the dividends gained from the reform and development of the pharmaceutical industry and eroding the rights and interests of the people. This not only hinders the reform and development of medical, insurance and pharmaceutical undertakings, but also jeopardizes the interests of the vast majority of people in the field of medicine and health, the NHC said on Tuesday.

The one-year campaign covers the entire chain of production, circulation, sales, use and reimbursement in the pharmaceutical industry, as well as pharmaceutical administrative departments, industry associations, medical and health institutions, pharmaceutical production and operation enterprises, and medical insurance funds, according to the NHC.

This concentrated campaign will focus on six aspects: administrative departments in the field of medicine using power for profiteering; the "key few" and major key positions in medical and health institutions; sales representatives for drugs, equipment, and consumables; social organizations that accept the management and guidance of administrative departments that use their position for self benefit; illegal acts by pharmaceutical enterprises during purchases and sales; and medical staff in violation of the standards for integrity, the NHC said.

Recently, some media outlets have reported on the suspension and postponement of some academic conferences due to the anti-corruption campaign. However, the NHC responded that what needs to be remedied is the illegal behavior of fabricating academic conferences out of thin air, carrying out illegal benefits transmission, or illegally sharing the sponsorship fees of academic conferences.

Medical experts said that the anti-corruption campaign in the sector this year is different from previous campaigns, as it is sweeping and more vigorous than ever.

Corruption in the medical sector is a serious issue that affects the credibility of the healthcare system and the interest of patients, said Zhong Chongming, an expert from the China Health Culture Association.

As the medical anti-corruption campaign has received widespread attention, some social platforms have exposed several corruption cases. In one case, Xu Bo, the director of the cardiac catheterization room at Fuwai Hospital, the Chinese Academy of Medical Sciences, was investigated by the discipline inspection team of the Central Commission for Discipline Inspection and the NHC of the State Supervisory Commission for suspected serious violations of discipline and law. At present, the case is still under investigation.

After confirming with related departments, the NHC said that online rumors about Xu using the opportunity of surgeries, consumables, and participation in the procurement of medical equipment bidding to accept bribes of up to 1.2 billion yuan ($165.6 million) are seriously inconsistent with the current investigation of the case.

Xinjiang is worth recommending to the world: foreign diplomats

A group of diplomats from nine countries, including Fiji, Mongolia and the Seychelles, visited northwest China's Xinjiang Uygur Autonomous Region from Monday to Saturday to discover the beauty of this stunning part of China.

In the six days, they visited several iconic sites in Xinjiang, including the International Grand Bazaar in Urumqi, the world heritage site of Tianchi Lake, the Grape Valley in Turpan, and the ancient city of Kashgar.

Xinjiang is a wonderous place with majestic scenery, friendly residents, and fully protected traditional culture, and it is worth being recommended to the whole world, the diplomats said.

MAJESTIC SCENERY

Crystal Gale P. Dampil, a diplomat of the Philippines in China, said this was her first trip to Xinjiang, and she grew excited about her tour as she looked out of the airplane window at the beautiful scenery below.

Anne Lafortune, ambassador of Seychelles to China, said Tianchi Lake is one of the most beautiful places she has ever seen, and she will happily act as an 'ambassador' for Xinjiang, recommending it to her friends.

Lafortune said she looks forward to more exchanges between the two countries in the future so that more tourists from Seychelles will visit Xinjiang.

Lafortune was also deeply impressed by the fruit grown in Xinjiang. She said she has never had such sweet fruit, and it will surely be one of the enduring memories of her life.

While visiting the ancient city of Kashgar, Tuvshin Badral, Mongolia's ambassador to China, joined in experiencing the making of nang, a kind flatbread typical of the region. He said that Xinjiang's food is varied and tastes great, adding that he hopes the two countries will have more food and cultural exchanges in the future.

FRIENDLY PEOPLE

While visiting Turpan, Ben Yacoub Adel, a counselor with the Tunisian Embassy in China, said he could feel the optimism and friendliness of the people of Xinjiang, both in their homes and in the streets.

In the ancient city of Kashgar, Luis Lopez, an Ecuadorian diplomat in China, was invited to dance with a young boy by the roadside. Their dancing attracted many tourists, who gathered around and took photos.

Lopez said that the people in Kashgar are full of energy and their dancing is very distinctive. He said he could see many fine qualities of Chinese culture in the peaceful and happy lives of the local people of all ethnic groups.

Wherever the group went in Xinjiang, they were warmly welcomed by local residents, said Jong Hyon U, a minister of the Democratic People's Republic of Korea's Embassy in China.

FULLY PROTECTED CULTURE

The delegation also visited the Xinjiang Museum, which boasts a collection of precious artifacts unearthed in Xinjiang. The artifacts capture the precious moments of history and the museum has preserved them well, said Manasa R. Tagicakibau, Fiji's ambassador to China.

While visiting a Buddhist grottoes site in Turpan, the group hailed China's efforts on protecting cultural heritage. Tuvshin Badral of Mongolia said the grottoes, built a thousand years ago, are milestones of history, incorporating religions and cultures, and China's experience in the preservation of cultural relics is worth learning from.

The delegation also visited a village known for making ethnic musical instruments for over 150 years. Keri Abrams, a diplomat of Guyana in China, said she truly felt the charm of intangible cultural heritage as she watched the traditional cultural program performed with unique Chinese instruments. China's efforts on protecting and developing cultures deserve praise, she said.

Thanks to the Chinese government's inheritance and protection of intangible cultural heritage, the traditional music and the exquisite instruments have been well preserved, said Manasa R. Tagicakibau of Fiji, adding that he hopes this valuable experience will be used as a point of reference around the world.

Joint patrol with neighboring countries necessary and crucial in cracking down on cross-border telecom fraud: Chinese experts

As telecom fraud has become increasingly rampant along the southwestern border of China, multiple regions in Southwest China's Yunnan Province have launched a new round of intensive anti-fraud campaigns. Officials warned that if individuals are lured to scam dens on the border, they may be sold "like pigs" and subjected to torture, or even face life-threatening situations. 

To combat cross-border crime, the Mekong River joint patrol consisting of law-enforcement authorities from China, Laos, Myanmar, and Thailand are actively taking action, which experts said are necessary and crucial in cracking down on illegal activities, given the complex security situation in border areas and the high mobility of criminal gangs. 

With the exposure of a series of scams under the guise of high-paying overseas jobs and the surprise hit movie No More Bets revealing the inner workings of online gambling fraud, the topic has drawn widespread attention among the Chinese public and particularly from public security services in Yunnan, which neighbors Myanmar, Laos and Vietnam and has been one the main locations of these crimes. 

According to data released by Yunnan's capital city of Kunming, from January to December 2022, the proportion of fraud cases involving overseas phone numbers accounted for 22 percent of the total in the city. So far in 2023, these cases have reached 14 percent of the total.

Various localities in Yunnan have issued warnings in recent days, noting that once people are smuggled to foreign countries, it is not well-paid jobs that are waiting for them but scam dens, where they will be forced to engage in illegal activities. Personal freedom is certainly restricted, and they will be required to complete large amounts of fraud tasks every day. Failure to complete the tasks may result in torture such as forced fasting, electric shocks and beatings. 

If they want to return to China, they are required to pay exorbitant "compensation" and "ransom" up to millions of yuan; if they fail to complete their tasks, they may be sold "like pigs" and even face life-threatening situations, said the warnings.

A Chinese national who has been living in Myanmar for almost 10 years told media on Wednesday that Chinese students studying abroad have become the new targets for scams, as they may not have timely access to the latest information at home and in turn have lower vigilance against scam calls.

Joint patrols with neighboring countries were launched on Tuesday as a fleet consisting of five law-enforcement vessels - three from China, one from Laos and one from Myanmar - departed from the Jingha Port in Yunnan as part of efforts to combat cross-border crimes arising from gambling scams in the Mekong River basin, the Xinhua News Agency reported.

Six suspects of telecom fraud were handed over by Myanmar to the Chinese police at Yangon International Airport and escorted back to China on Wednesday. One of the suspects is a key figure in a gambling fraud syndicate and a prime target in the crackdown, media reports said.

In June, the first batch of six suspects involved in fraud cases in Myanmar were returned to China.

Experts noted that as transnational gambling fraud is even more lucrative than drug trafficking and very difficult to eradicate, it is necessary and crucial for countries in the region to collaborate in targeted operations. 

Wu Fei, an expert on Southeast Asia studies, pointed out that some fraud groups are scattered in remote areas of northern Myanmar and have connections with gangs involved in the "Golden Triangle" drug trade, making it more difficult to combat them. After they establish a foothold in underdeveloped regions, these fraud groups can "stimulate" local economies and thus prompt the protection and even involvement of local officials, Wu told the Global Times on Wednesday. 

As many hideouts are located in border areas with strong mobility and networks in Southeast Asia, it is extremely challenging for a single country to conduct operations such as victim rescue or gathering information about crime hotspots, Wu noted. 

The importance of combating cross-border fraud and related crimes lies not only in maintaining a country's image but also in ensuring the development of tourism and international trade. 

This is particularly concerning as the tourism industry is a vital sector for many Southeast Asian countries, the expert said.

What's more, the worrisome security situation may also hamper the timely restoration of people-to-people exchanges in the post-pandemic period, causing unnecessary misunderstandings and conflicts.

The Chinese, Thai, and Laotian ambassadors to Myanmar held a trilateral meeting to coordinate efforts in combating gambling fraud, according to a notice issued by the Chinese Embassy on Tuesday.

The three parties unanimously agreed that the current prevalence of gambling fraud in the region seriously undermines the safety of people's lives and property. They are fully coordinating with Myanmar authorities to conduct investigations and rescue operations, as well as assisting Myanmar in intensifying efforts to combat fraud syndicates. 

China's top cyberspace regulator to regulate activities of athletes' fans for the network environment of the Asian Games in Hangzhou

China's top cyberspace regulator announced on Monday the launch of a two-month nationwide special campaign to regulate the network environment for the 19th Asian Games in Hangzhou, East China's Zhejiang Province, addressing problems such as fan conflicts involving insults and comment manipulation.

According to the notice released by the secretary bureau of the Cyberspace Administration of China, the Copyright Management Bureau of the Central Publicity Department and the office of the Organizing Committee of the 19th Asian Games in Hangzhou, the campaign kicked off on Monday and will run through October 29. The campaign will focus on eight categories of prominent problems.

Issues to be addressed include the incitement of insults among fans and the manipulation of comments.

The cyberspace regulator will also rectify the problem of excessive sensationalism and "fan circle culture" in the sports event coverage.

The campaign will target "human flesh search" activities that deliberately expose personal information of athletes, referees and coaches, leading to online violence, as well as the release of unlawful and harmful information that spreads insults, defamatory, abusive and attacking content, causing harm to individuals' physical and mental health.

The authority will also regulate internet news and information service activities without authorization or permission, as well as activities that create and disseminate fake sports event videos with generative artificial intelligence (AI) technology.

Other behaviors that will be rectified during the campaign include spreading false information about the Hangzhou Asian Games and Asian Para Games, the related regional public policies and social and livelihood issues, fabricating rumors about disasters and accidents, illegal activities, food and product quality issues, and other false information that could cause panic.

Besides, unlawful marketing activities that promote commodities and services or collect personal information, private identification or biometric information in the name of the sports events will also be targeted.

Computer program bests world champion 4-1 in strategy game Go

The notoriously intricate strategy game Go has a new champion.

AlphaGo, Google’s Go-playing computer program, has topped Lee Sedol, the world’s reigning player, in a five-game match played over a week in South Korea.

The program, a breakthrough in artificial intelligence, learned to play Go by watching human experts and by playing millions of games against itself. It stepped into the world spotlight in January, when it beat Fan Hui, the European champion, 5 games to 0. Victory wasn’t certain against Sedol, though, a player often described as “legendary.”

But by March 12, Sedol was officially sunk. AlphaGo had defeated the human in three consecutive games. The only question left was whether the program would sweep the match. In game 4, however, Sedol defied expectations and pulled out a win. In game 5, AlphaGo made a big mistake early on, but clawed its way back in a match that Google DeepMind’s Demis Hassabis tweeted was “nail-biting.”

Google DeepMind, the artificial intelligence company that developed AlphaGo, will give away the $1 million in prize money, splitting it amongst UNICEF, science, technology, engineering and math charities, and Go organizations.

Physicist’s story of science breaks historians’ rules

BALTIMORE — For centuries, clashes between science and religion have made waves within society at large and in the academic world. You probably haven’t heard very much, though, about similar clashes between science and history.

Yet scientists and historians have fundamentally different perspectives on history, especially when it’s the history of science. Scientists tend to celebrate the discoveries of the past that built the knowledge of the present. Historians argue that the scientists of the past should be viewed through the lens of their own time, not evaluated on the relevance of their work to today’s textbooks.

One prominent physicist who objects to the historians’ modus operandi is Nobel laureate Steven Weinberg of the University of Texas at Austin. His 2015 book To Understand the World unabashedly analyzes the scientific past in the light of the present. “I knew from the beginning that I was being naughty,” Weinberg said March 14 at a meeting in Baltimore of the American Physical Society.

In technical terms, Weinberg was engaging in “Whig” history (an allusion to criticisms of British historical accounts involving a prominent political party). Whig historians write (or rewrite) history as a story validating the chain of events that created present-day circumstances. Most historians argue that such an approach distorts the record of the past. Much of what happened in the past had little to do with how things are now, and historical actors certainly had motives other than creating a future they couldn’t even have imagined. “We don’t want to read history only from the winners’ point of view,” commented historian David Wootton, also speaking at the physical society meeting.

But limiting historical accounts to evaluating the past “on its own terms,” without admitting current knowledge into evidence, misses much of the story, Weinberg asserts.

And as Weinberg points out, it’s often hard to understand the past on its own terms anyway. Especially when studying early Greek philosophers, it’s impossible to know very much about the conditions under which they worked and the influences that shaped their thought. Even many of their own writings are missing or fragmentary.

“Our knowledge of present science provides a contrast to the attitudes and methods of the past, attitudes and methods that often obstructed progress,” Weinberg said.
Of course, the notion of progress itself is one of those concepts that some historians deny; it implies a value judgment that things now are somehow better than they used to be. But in science, progress of some sort is very hard to deny. Wootton, the historian, agrees with Weinberg on that point. Wootton believes many historians go too far in denying the notion of progress in many fields, with science being the most prominent example.

“The progress has been real and needs to be studied and explained,” Wootton said. “Understanding the past in its own terms is not enough” — a point he also makes in his recent book The Invention of Science.

Other historians view their task more narrowly, insisting that scientists of the past should be studied in light of their efforts to solve the problems posed in their own day within their own worldview. But that is not the story of science’s past that interests Weinberg.

He agrees that early scientists dealt with different problems. “Scientists of the past were not just like scientists of today who didn’t know as much we know. They had completely different ideas of what there was to know, or how you go about learning it,” he said. “But the point of scientific work is not to solve the problems that happen to be fashionable in your own day — it is to learn about the world.”

So that makes the stories that historians like to tell irrelevant (to him).

“It is the history of the change in the attitudes of what was there to know, and how do you find it out, that seems to me the most interesting … story.” That’s the story, Weinberg believes, that helps in understanding how science has succeeded and perhaps even helps identify present-day mistakes.

“The real story is the progress of science from an earlier day when the most intelligent and well-informed people in the world did not know how to address the mysteries of nature,” he said. “We’re certainly not finished, and we’re undoubtedly still making mistakes. But we have amassed a large amount of reliable knowledge, and more important we have developed techniques for deciding when knowledge really is knowledge or just a mistake. It is a great story. It’s not at an end. But we have learned some things, and if we don’t use the things that we have learned, then the story we tell has no point.”

Forgetting can be hard work for your brain

NEW YORK — Sometimes forgetting can be harder than remembering. When people forced themselves to forget a recently seen image, select brain activity was higher than when they tried to remember that image.

Forgetting is often a passive process, one in which the memory slips out of the brain, Tracy Wang of the University of Texas at Austin said April 2 at the annual meeting of the Cognitive Neuroscience Society. But in some cases, forgetting can be deliberate.
Twenty adults saw images of faces, scenes and objects while an fMRI scanner recorded their brains’ reactions to the images. If instructed to forget the preceding image, people were less likely to remember that image later. Researchers used the scan data to build a computer model that could infer how strongly the brain responds to each particular kind of image. In the ventral temporal cortex, a part of the brain above the ear, brain patterns elicited by a particular image were stronger when a participant was told to forget the sight than when instructed to remember it.

Of course, everyone knows that it’s easy to forget something without even trying. But these results show that intentional forgetting isn’t a passive process — the brain has to actively work to wipe out a memory on purpose.

Piggybacking tadpoles are epic food beggars

Tadpoles don’t cry to get their way. But some of them sure can beg.

Each bout of hungry-baby drama among mimic poison frogs (Ranitomeya imitator) occupies both parents for hours. The tadpoles get so crazy-frantic that researchers wanted to know whether the begging is an honest call for help or a histrionic scam.

Frogs can lay globs of eggs by the thousands and leave them to fend for themselves. But the two-to three-egg clutches of mimic poison frogs (the only known monogamous frogs) get coddled, says Kyle Summers of East Carolina University in Greenville, N.C. Dad repeatedly checks in, sitting on the eggs and shedding some paternal pee if they’re drying out.
When the eggs hatch, dad gives each tadpole a piggyback ride to its own private pool. To find a little rainfall cupped between a leaf and stem, he’ll haul youngsters four meters or so. “A bit of a hike,” Summers says, since dad is only about a centimeter or two long himself.

These baby pools are pretty empty: home to only some algae, maybe some small insects. “The good news is that your offspring are not likely to get eaten; the bad side is that they don’t have anything to eat,” Summers says.
This is where the begging comes in. Frogs can’t make milk like mammals or regurgitate bugs like birds. But this species is one of the rare frogs whose moms, after considerable persuading, will lay an unfertilized egg for the tadpoles’ breakfast.
When parents show up on their weekly visit, a youngster stops regular swimming, noses up to a parent and goes into a frenzy of vibrating its tail. “The parent cannot miss a hungry tadpole,” Summers says.

Bouts of persuasion go on for several hours as the tadpole begs, stops, begs more and then more. Mom often makes several false starts, entering the pool but leaving it without any egg action. During all this, “dad will be the cheerleader,” calling in trills and stroking her, Summers says.

Analyzing tadpole frenzies in the lab, Summers’ then-student Miho Yoshioka found that tadpoles on short rations begged more as hungry weeks dragged on. Parents fed these hungrier tadpoles more reliably than the babies that researchers slipped treats to, Yoshioka, Summers and Casey Meeks report in the March Animal Behaviour. Overall, the researchers conclude, the relentless frenzy shows honest need, not tadpole greed.
