1 . A humanoid robot can relay video and touch sensations to a person wearing a haptic (触觉内) feedback suit and a virtual reality (VR) headset hundreds of kilometres away, offering away for people to attend events without travelling.
The iCub 3 robot is a 52-kilogram, 125-centimetre-tall robot with 54 joints across its body. Its head contains two cameras where a human’s eyes would be, and an Internet-connected computer where the brain would go. Along with the cameras, sensors covering its body send data to the robot’s “brain”. These sensations are then reproduced on a suit and VR headset worn by a remote human operator.
When the operators react to what they see and feel, the suit’s sensors pick up the movements and the robot matches them. “The key is to translate every signal and bit of digital data that can be sent through the network.” says Stefano Dafarra, who was part of the iCub3 team. There can be a small delay of up to 100 milliseconds to capture and transmit the visual shots, but the operator can case this by moving slightly slower than normal.
The team demonstrated the robot at the Venice Biennale, where it wandered through an exhibition while its operator stood 290 kilometres away in Genoa. Dafarra hopes people will use the iCub3 to attend events remotely, reducing the need to travel. “But at present, a fall could be hugely damaging to the robot, and it’s uncertain whether it could stand up again on its own," he says.
“iCub3 is an interesting robot and offers clear advantages from the previous versions.” says Jonathan Aitken, whose laboratory owns a prior version of the robot. However, he is disappointed that the team wasn’t clear in its research about the data transmission requirements of the new version of the robot. “It would be good to know just how much data was required, and what the upper and lower bounds were.” he says.

2 . Many people have dreamt to find a cancer cure. Now, a pill might provide some insight into their dreams.
The medicine, AOH1996, also called the “cancer-killing pill”, explicitly targets the protein that encourages cancer cells to spread across the body. It prevents proliferating cell nuclear antigen (PCNA 细胞增殖核抗原) with a tiny molecule. Up to August 2023, it is being evaluated in Phase I clinical studies for the treatment of solid cancers.
Cancer is a condition in which abnormal cells continue to proliferate uncontrollably, causing the tissue to be destroyed. About one in six deaths were due to cancer in 2020, making it the top cause of death globally.
According to a recent study published in Cell Chemical Biology, City of Hope researchers have discovered a novel method to treat cancer using a special tablet that can get rid of solid tumors. AOH1996 differs from other targeted cancer therapies in this respect, where other approaches may cause a tumor to change and develop more resistance to treatment.
According to City of Hope Professor Linda Malkas, the research team created a medicine specifically targeting the kind of PCNA seen in cancer cells since data indicate that PCNA is distinctively changed in cancer cells. The novel cancer medicine acts like a snowstorm closing a significant airport, stopping only flights from and to aircraft carrying cancer cells.
“Results have been promising. AOH1996 can prevent tumor growth in cell and animal models. The drug is currently in Phase I clinical trial in humans at City of Hope.”
Treatment of lung, brain and skin cancers with AOH1996 has shown to be effective. It kills specific cells by stopping them from replicating (复制) typically. To assess this medicine for potential future use, more clinical studies are planned.

4 . A tree has roots (根). People have roots too. If you get to the root of a problem, you will solve it. It’s the same thing with words. Dig deeply into a big, unfamiliar word and you will understand where it came from.
As readers, especially those reading in a second language, we need to deal with the text as if we were detectives (侦探) looking for information to unlock (解开……秘密) the unknown. Like any good detective arriving on the crime scene, the first thing to do when meeting a new and difficult word is to judge the situation, to look at everything that is known and see if it helps us to understand what it means.
As you know, prefixes (前缀) and suffixes (后缀) can be added to the beginning or end of words to change the meaning. Know them, and you will have the word building power. But root words are the key (关键). Take time to learn a few of these, put them in your memory, and you will become a master word detective.
Let’s look at one common root word used in English. “Alter” from the Latin(拉丁语的) word means “other”. When you meet this root word, you know that the bigger word has something to do with “other”. Examine the word “alternate”. Can you find the Latin root in it?
• If you and your friend like to eat out, first you pay and the other pays the next time. You are alternating paying.
• If you go to the movies on alternate Saturdays, you go on one Saturday, but not the other Saturday.
• If you have no alternative, you have no other choice.
Learn as many root words as possible in the language you are studying. Then use your “rooting for words” skills. Like any new skill, practice and hard work are always paid back.
1. If Jim and Lily go to the movies, which one below is “alternating paying”?| A．Jim pays every time. | B．They each pay half. |

5 . Recently, I was walking with some parents when we came across a five-pound note lying on the ground. We stood around it for a moment, a bit awkwardly, until someone suggested putting it on a nearby bench. Then one of the parents remarked that we’d probably have behaved differently — that is, we would have just taken the money — had we been alone.
This relates to a classic question in studies of human generosity: do we behave more selfishly when we aren’t being observed? The debate goes on across the psychological and biological sciences, as well as in popular culture, about whether kindness can exist in a competitive world.
Yom Kippur is a Jewish (犹太人的) religious holiday when Jewish people fast and ask for forgiveness for the wrongs they’ve committed. One of the points of Yom Kippur is to behave better regardless of who is watching. There’s an evolutionary beauty to the teachings of Yom Kippur, which are the products of thousands of years of cultural changes and evolution.
The Maasai people of Kenya practice osotua: relationships between people that operate based on need. When someone forms an osotua relationship with another, they enter into an unwritten contract to help their partner in times of need. And hunter-gatherer groups, which can represent the circumstances our species evolved in, have many similar examples.
Cultural evolution helps to explain the existence and complexity of these systems. Cultural changes are far faster than biological evolution, allowing intelligent species like humans to develop behavioral adaptations for managing complex social environments. Osotua, or any other practice that helps to maintain good treatment of others in society, is the result of tens of thousands of years of cultural trial and error. The customs passed down over time are those that help us to develop as cultural groups.
The study of those changes has helped us to understand how we successfully spread around the world as cooperative groups. Biological evolution has helped humans be more cooperative, but cultural changes have accelerated this process.
Cultural evolution helps us to overcome our selfish natures. Try to understand rules before you ignore them — and next time you find a fiver on the ground, you might think about the awkward situation your discovery represents.

6 . We may weep for the dodo, but could and should we bring this lovely bird back from the dead? De-extinction is the science of restoring lost species and it has been in the news for decades.
The story in modern times began in 1990 when Michael Crichton published his science fiction novel Jurassic Park, in which he imagined a world where scientists were able to bring dinosaurs back to life. Crichton imagined that polymerase chain reaction (PCR) technology could be a way to amplify (放大) tiny quantities of dinosaur DNA and thus build a living embryo.
Sadly, biologists soon realized that DNA in fact breaks down super-fast; even after 100 years, DNA from museum skins of dodos was decayed (腐烂) beyond repair. They could be sequenced (测定序列) using massive computational power, but then only with considerable uncertainty. And even if you capture a DNA sequence, there’s still the problem of how you get living cells to read that sequence and express proteins that make the dinosaur or the dodo.
But why would anyone want to see mammoths, or something like them, roaming (漫游) present-day Siberia? Well, they were undoubtedly amazing beasts. As well as hunting them, our distant ancestors painted their likenesses in caves across Europe. Fascinating as they may be, there's some ecological justification for the project too.
It was this diversity of land surface, broken up by heavy limbs and randomly fertilised by faeces (排泄物), that supported so much flora (植物群). Without the mammoths, that diversity disappeared. Return them and landscapes would once again be with a variety of species, including flowers and bushes.
True, it’s not de-extinction in the sense of bringing a long-dead species back to life. Instead it’s more like making a “dodo” by engineering a modern pigeon, its closest relative, to become huge and flightless. The result would be a big, fatty pigeon that, whether it looked like a dodo or not, would probably fulfil some of its ecological roles.
As a palaeontologist, I would of course love to see living dinosaurs, mammoths and dodos. In some ways, though, I am relieved that the optimistic claims for cloning and genetic technologies have not been borne out. The slowdown gives us time to consider the outcomes—and hopefully avoid some of Michael Crichton’s more fevered imaginings.

7 . The cultivation of plants by ants is more widespread than previously realized, and has evolved on at least 15 separate occasions.
There are more than 200 species of ant in the Americas that farm fungi (真菌) for food, but this trait evolved just once sometime between 45 million and 65 million years ago. Biologists regard the cultivation of fungi by ants as true agriculture appearing earlier than human agriculture because it meets four criteria: the ants plant the fungus, care for it, harvest it and depend on it for food.
By contrast, while thousands of ant species are known to have a wide variety of interdependent relationships with plants, none were regarded as true agriculture. But in 2016, Guillaume Chomicki and Susanne Renner at the University of Munich, Germany, discovered that an ant in Fungi cultivates several plants in a way that meets the four criteria for true agriculture.
The ants collect the seeds of the plants and place them in cracks in the bark of trees. As the plants grow, they form hollow structures called domain that the ants nest in. The ants defecate (排便) at designated absorptive places in these domain, providing nutrients for the plant. In return, as well as shelter, the plant provides food in the form of fruit juice.
This discovery prompted Chomicki and others to review the literature on ant-plant relationships to see if there are other examples of plant cultivation that have been overlooked. “They have never really been looked at in the framework of agriculture,” says Chomicki, who is now at the University of Sheffield in the UK. “It’s definitely widespread.”
The team identified 37 examples of tree-living ants that cultivate plants that grow on trees, known as epiphytes (附生植物). By looking at the family trees of the ant species, the team was able to determine on how many occasions plant cultivation evolved and roughly when. Fifteen is a conservative estimate, says Campbell. All the systems evolved relatively recently, around 1million to 3 million years ago, she says.
Whether the 37 examples of plant cultivation identified by the team count as true agriculture depends on the definitions used. Not all of the species get food from the plants, but they do rely on them for shelter, which is crucial for ants living in trees, says Campbell. So the team thinks the definition of true agriculture should include shelter as well as food.

8 . A moment occurs in the exchange between professor and student when each of us adopts a look. My look says, “What, you don’t understand?” Theirs says, “We don’t. And we think you’re making it up.” We are having a problem. Basically, we’ve all read the same story, but we haven’t used the same analytical approaches. It may seem at times as if the professor is inventing interpretations out of thin air.
Actually, the truth is that as the slightly more experienced reader, the professor has acquired over the years the use of a certain “language reading”. Besides, he has grasped three professional tools-memory, symbol and pattern. These items separate the professional readers from the ordinary ones.
English professors are cursed with memory. When reading a new book, I constantly seek out connections and inferences, recalling faces and themes from past readings. I can’t not do it, although there are plenty of times when that ability is not something I want to exercise. This does not necessarily improve the experience of popular entertainment.
Professors also read and think symbolically. Everything is a symbol of something, it seems, until proven otherwise. We ask: What does the thing over there represent? The kind of mind that works its way through undergraduate and then graduate classes in literature and criticism tends to see things as existing in themselves while also representing something else. This tendency to understand the world in symbolic terms is enhanced by years of training and rewards the symbolic imagination.
A related phenomenon in professorial reading is pattern recognition. Most professional students of literature learn to take in the specific detail while seeing the patterns that the detail reveals. Experience has proved to them that life and books fall into similar patterns. Literature is full of patterns, and your reading experience will be much more rewarding when you can step back from the work, even while you are reading it, and look for those patterns.

9 . Coming into the town of Santa Catarina Palopó, in the highlands of Lake Atitlán in Guatemala, the first thing you notice is the bright colors. Most of the buildings along the main street are eye-catching, in deep, varied hues of blues and greens; interspersed with red and yellow to form complex patterns and designs.
Santa Catarina Palopó was once a sleepy town of 5,000 people, most of them indigenous (土著的) and dependent on agricultural work. As agriculture began to dry up here, decline for the town and poverty for many of its families came. To deal with poverty and stimulate economic growth through tourism, a small but mighty group of laborers, artisans, domestic workers and stay-at-home moms created the Pintando Santa Catarina Palopó project.
The project was initially to paint all 850 homes and buildings in bright colors, in an effort to change the hillside town into a work of art. “We wanted to paint the houses with colors and figures that represent the community,” says the project’s executive director Stephany Blanco. “A range of designs were created so that families can choose designs for their house that are representative of the family.”
One of the most representative characteristics of the region is the blue huipil, a traditional blouse which has been worn prominently by local women since the 16th century. That deep sky blue was chosen as the primary color for the Pintando project, with secondary colors found in the sunsets and the nearby lake to make the design more attractive. As for the designs that would be used, they would also find inspiration in local culture, symbols such as volcanoes, flowers, Mayan-styled butterflies and the national bird of Guatemala.
Each week, local artists, community members and tourists pick up paintbrushes to make buildings colorful. “At first, the idea of the project left many unsure about participating, but now you can see a considerable difference in the town,” Melissa Whitbeck said. “The color of the buildings is believed to improve the quality of life of the people. It uplifts the people’s mood and encourages them to be proud of where they come from.”

10 . When Amelia thinks about her freshman year two years ago, she remembers being tardy to her 8 a.m. first period class from time to time. “It was so hard to wake up in the morning,” she said. “I had to bike to school and I lived on the other side of the island.”
Like other teens, mornings area struggle because she had several hours of homework and extracurricular activities the night before, but research shows that’s not the entire story. According to psychotherapists, Heather Turgeon and Julie Wright in their book Generation Sleepless, today's teens are sleepier than ever and earlier school start time is disturbing their body's circadian (昼夜节律的) rhythm.
“One of the things that happens somewhere around age 12 is that their brain clock becomes set to a later pace,” said Turgeon, which put sateen about two hours behind the sleep schedule of a young child or an adult. “That means they want to go to sleep later and they want to wake up later,” she said.
“We consider adequate sleep —the very lowest amount—to be about eight hours,” said Wright. However, the average sleep time for high school students is usually about 6.5 hours. And missing out on just a couple hours of rest each night has negative consequences for developing teenage brains.
When a teen is tired, the amygdala—which is the part of the brain that responds to danger—will become more active. And the parts of the brain that are in charge of judgment become less active. Sleep issues are commonly associated with anxiety, depression, bipolar disorder (双相情感障碍) and ADHD (多动症). “We see teens with very serious mental health issues and accidents and soon things that parents really worry about—and getting enough sleep addresses those issues.”
Even with research showing that letting students sleep well contributes to better academic performance, lower truancy (旷课) rates and improved mental health, there has been pushback from parents and school districts about delaying the start of the school day.
