2 . Nasugraq Rainey Hopson is an author and illustrator (插图画家). She has written short stories and made art inspired by her Iñupiaq culture. The Iñupiaq people are native to Alaska, the US. Hopson’s first and only novel to date, Eagle Drums, is set in Iñupiaq tales about a great festival. The great festival is still celebrated locally today.
In the book, the hero Pina struggles with the suffering from losing his brothers, who have traveled to a nearby mountain and never returned. Pina decides to go to the same mountain, trying to uncover the facts, where he happens to meet Savik, who gives Pina a choice: To follow him or to meet the same fortune as his brothers. Pina’s decision takes himself on a journey that exposes himself to the dances and songs that are part of Iñupiaq culture. Eagle Drums describes aspects of Iñupiaq life as a world that doesn’t exist much in the current world, such as walking in the tundra (苔原) and imagining mythological beings and talking animals everywhere. It will definitely inspire the teen magical thinking in its beauty.
Hopson wants to write more Iñupiaq stories. “We have a lot of oral history and stories in our culture,” she says. Hopson explains that Iñupiaq people use their voices, facial expressions and movements to express emotions as they tell a story. “But you can’t do that when you’re writing,” she says. “It’s very uncomfortable, in a way, to have to write down something that is a performance.” But she’s up for the challenge.
Eagle Drums is for anyone who is looking for a vivid adventure. Hopson says that when Iñupiaq kids read her work, they get excited about seeing something from their own area and their own culture. Other kids who read her work tell Hopson they’re excited about experiencing a story they’ve never experienced before in a new place. “You know, that’s the best part, hearing feedbacks,” she says.

3 . Atomic shapes are so simple that they can’t be broken down any further. Mathematicians are trying to turn to artificial intelligence (AI) for help to build a periodic table of these shapes, hoping it will assist in finding yet-unknown atomic shapes.
Tom Coates at Imperial College London and his colleagues are working to classify atomic shapes known as Fano varieties, which are so simple that they can’t be broken down into smaller components. Just as chemists arranged element s in the periodic table by their atomic weight and group to reveal new insights, the researchers hope that organizing these atomic shapes by their various properties will help in understanding them.
The team has given each atomic shape a sequence of numbers based on its features such as the number of holes it has or the extent to which it bends around itself. This acts as a bar code (条形码) to identify it. Coates and his colleagues have now created an AI that can predict certain properties of these shapes from their bar code numbers alone, with an accuracy of 98 percent.
The team member Alexander Kasprzyk at the University of Nottingham, UK, says that the AI has let the team organize atomic shapes in a way that begins to follow the periodic table, so that when you read from left to right, or up and down, there seem to be general patterns in the geometry (几何) of the shapes.
Graham Nib lo at the University of Southampton, UK, stresses that humans will still need to understand the results provided by AI and create proofs of these ideas. “AI has definitely got unbelievable abilities. But in the same way that telescopes (望远镜) don’t put astronomers out of work, AI doesn’t put mathematicians out of work,” he says. “It just gives us new backing that allows us to explore parts of the mathematical landscape that are out of reach.”
The team hopes to improve the model to the point where missing spaces in its periodic table could point to the existence of unknown shapes.

4 . Here are four small places in England, all packed with delightful scenery and more.
Lavenham. Suffolk
In the town, ancient buildings lean casually into one another. As a result, wandering down the high street feels like walking through a fairy tale or a Hollywood movie as Lavenham has appeared in many Hollywood movies. Behind the high walls are several excellent restaurants, but first time visitors should go to the Lavenham Guildhall, where you can drink tea in a well-preserved Tudor room.
Shaftesbury, Dorset
Home to Gold I Hill, the cobblestone street known as “one of the most romantic sights in England”. Shaftesbury is a major charmer. The tiny Dorset town is also home to the ruins of Shaftesbury Abbey, built in 888 AD by King Alfred, a man well-known for creating England. Shaftesbury is also surrounded by a wealth of incredible countryside rich in picnicking potential including Duncliffe Wood and Melbury Beacon.
St Ives. Cornwall
St Ives used to be little more than a traditional fishing village, but now it has developed into a popular coastal town. Its soft, sandy beaches regularly win awards and there are also plenty of top seafood dining options. The town has even gained a reputation as a serious arts center, with lots of outstanding galleries led by the Tate St Ives, which features attractive modern art exhibitions focusing on British artists.
Castle Combe. Wiltshire
Recognized as the “pretticst village in England”. Castle Combe is famous for its handsome honey colored stone houses and flower-lined lanes (小巷) which have decorated countless postcards and magazine covers over the years.

6 . Dogs may have earned the title of our best friends through their interactions with humans, but now researchers say these social skills could, be present shortly after birth rather than being learned.
To better understand the role of biology in dogs’ abilities to communicate with humans, the researchers studied 375 eight-week-old service dogs. They looked at how these dogs performed in a series of tasks designed to measure their communication skills. The puppies were still living with their littermates (同窝出生者) and had not been sent to live with a volunteer puppy raiser, making it unlikely that they had learned about his or her behavior.
In the first task, a person hid a treat beneath one of two overturned cups and pointed to it to see if the puppy could follow the gesture. Since dogs are good at using noses to find things a treat was also taped to the insides of, both cups. In the second task, puppies watched as the researchers placed a yellow, block next to the correct cup, instead of pointing to indicate where the puppy should look for the food.
The third task was designed to observe puppies’ tendency to look at human faces. The researchers spoke to the puppy in a voice people sometimes use when talking to a baby. They then measured how long the puppy fixed a stare on the human.
In the last task, researchers sealed a treat inside a closed container and presented it to the puppy. They then measured how often the puppy looked to the human for help in opening the container.
The study found that while many of the puppies were responsive to humans’ physical and verbal cues, very few looked to humans for help with the unsolvable task. Researchers said, “This suggests that while puppies may be born knowing how to respond to human-initiated communication, the ability to initiate communication on their own may come later.” The next step will be to see if specific genes that may contribute to dogs’ abilities to communicate with humans can be identified.

7 . I’ve never had a great sense of direction. And I often wander into shops and, upon coming back out, can’t remember which way I’ve come from — left or right? Many people are like me, and why do some constantly have no idea where they are?
The hippocampus (海马体) is a region of the brain associated with memory and involved in sense of direction. And a nearby region has also been associated with sense of direction. There are four known types of navigation-related neurons (神经元), found in these regions place cells, grid cells, border cells and head direction cells.
In short, you can think of place cells as an internal cognitive (认知的) map; they identify where you are. Grid cells are like a GPS system in our brain; they tell us about the relationship of this place to other places we’ve been to. Border cells respond to the presence of environmental boundaries at a specific direction and distance from us. Lastly, head direction cells are activated when our head faces a specific direction. These cells will fire electrical impulses when we enter familiar locations, with each group of cells relating to a specific place.
Our reliance on GPS and smartphones may have decreased the ability to use our internal maps. Older adults who regularly used GPS had less activity in their hippocampus, compared with those who did not use GPS. They also performed slightly worse in a cognition test. In contrast, a study involving London taxi drivers found they significantly larger hippocampus than ordinary people.
You can improve your way-finding ability specifically by practicing the skill, according to Aziz, PhD of neurology at Temple University School of Medicine. “The more you get out and go to places, the better,” he says. Physical exercise improves the blood flow to the brain, while mental exercise, such as doing puzzles or learning a new language, stimulates the development of new nerve cells and connections in your brain.

10 . Microscopic particles (微观粒子) from outer space are also called space dust. They’re in the dirt on the ground and on your roof. They may discomfort your nose. They have settled all over our planet.
Despite their widespread presence, finding space dust isn’t easy. One place that the particles show up more easily is Antarctica. Around a decade ago, Matthew Genge at Imperial College London spent seven weeks searching for and collecting dust there.
The disadvantage of collecting dust from Antarctica is the high cost and complications of travelling there. That’s why Penny Wozniakiewicz of the University of Kent in the UK has focused on her research closer to home. The key is to collect material from a fairly undisturbed spot. She seeks the rooftops of old buildings in the UK as the source of her samples.
She focuses on these roofs because they are old and more untouched than modern buildings. What’s more, historic buildings usually have well-kept records that indicate when conservation and cleaning have been done. That makes it easier to determine how long space dust has been collected and gives researchers insight into what other particles might be present in the dust they collect. This allows them to more efficiently remove the Earth stuff, and focus on the space stuff.
“The idea is to actually take something you can barely see on your finger, and then make it much bigger so you can hold it in your hand,” says Wozniakiewicz. Each year, approximately 100 billion particles of space dust land on Earth, carrying secrets from outer space and offering glimpses into the formation of planetary systems. These particles not only contain water but also organic molecules (有机分子); they potentially serve as the building blocks for life on Earth. Space dust could, therefore, tell scientists about the complex relationship between these celestial bodies (天体) and Earth. It acts as a bridge, connecting us to the wider space.
