1 . 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.

2 . Fresh fish should have a mild smell. Strong fishy smells are the first signs to go bad. How do the fishy smells come from?
It can be several days from when the fish are caught to when they reach the supermarket. In that time, bacteria that grow naturally in fish start to consume a substance called trimethylamine N-oxide(TMAO)in fish. These bacteria change TMAO into trimethylamine (TMA), the substance responsible for the fishy smells. Bacteria in fish can also change lysine(赖氨酸)into cadaverine(尸胺), a substance that’s associated with breaking down the fish once they are caught and giving off fishy smell.
Chemical reactions can also lead to fishy smells. This happens through the oxidation(氧化)of fat. Fish are an important source of omega-3 fatty acids. When these fats are exposed to oxygen, they oxidize and break down into the substance that you can smell.
To slow down the fishy smell, what is beyond question is that the less time between when the fish are caught and when they reach the kitchen, the better. But today, fish are often flown across the globe. To keep smell-producing bacteria at bay, the fish must be frozen or kept at the low temperature possible as soon as they are caught and cleaned.
Controlling fat oxidation can function as well, especially for fattier fish species. While freezing slows bacterial growth, it does not stop fat oxidation. This reaction will occur as long as oxygen is present. Fatty fish are usually not frozen because, despite the cold temperature, they’re going to oxidize pretty fast unless they are stored in a low oxygen container. That’s why those species are often canned.
It’s also important to remember that smell is not always an indicator of safety, especially in processed fish products. “What you might consider the fishy smell may be a delicacy in another culture,” said Carl A. Batt, a professor of food science at Cornell University.

Harrison’s home was in a small village. He was a 17-year-old high school student who walked to and from school by himsclf every day. He hadn’t had many friends since growing up, so he always felt lonely.
On his way to his school, he needed to pass through a large woods where birds sang and flowers bloomed. Animals kept each other company and played in the woods, which contrasted (形成对比) sharply with Harrison’s loneliness. Whenever he saw these sights, he longed to make new friends with whom he could play.
One day, on his way from his school, Harrison spotted a red object in a tree. When he got closer, it turned out to be a balloon with a string (细绳) tied to it. The balloon’s stringwas wrapped around a branch, making it impossible to fly away. Just as Harrison was getting bored, he reached up to untie the balloon. He thought it was just a balloon, but then herealized there seemed to be something inside the balloon.
Out of curiosity, Harrison slowly untied the balloon and saw a piece of paper in it. It was a letter, but it was a little hard to read. He picked up the letter and put it in the sunlightfalling from the woods and read it aloud:
If you have found this letter, it means my balloon finally reaches the destination. I used the balloon to see how far my letter would travel. I want this balloon to fly to a teenager like me and I hope to be friends with you. I launched it from Wisconsin Academy on May 1. Please write back to me and tell me where and when you found it. Besides, I’m happy to know something about you.
Sincerely,
Joe Smiths
After reading the letter, Harrison felt unusually excited. He couldn’t believe that hecould receive a letter in the woods. He wanted to write back to Joe right away, so he started running home.

4 . Animal appear to predict earthquakes by sensing electricity in the air — the first study to find reliable evidence of the phenomenon has shown.
Cameras revealed an “amazing” drop in the number of animals up to 23 days before a major quake hit their rainforest home at Yanachaga National Park in Peru. Lead scientist Dr Rachel Grant, from Anglia Ruskin University, said, “The results showed that just before the earthquake, animals’ activity dropped right down.”
On a normal day the cameras placed around Yanachaga National Park record between 5 and 15 animals. But in the 23 days before the earthquake, the number of animals dropped to five or fewer per day. No animals were photographed at all on five of the seven days immediately before the quake.
Another study showed that animal activity remained normal in the park over a different period when seismic (地震的) activity was low. Co-author, professor Friedemann Freund, said, “The cameras were located at an altitude of 900 meters. If air ionization occurred, the animals would escape to the valley below, where there were fewer positive ions ( 离子). With their ability to sense their environment, animals can help us understand small changes that occur before major earthquakes.”
Other evidence suggested that before the earthquake, the air around the high mountain sites filled with positive ions that can be produced when rocks are placed under stress. Positive ions have been known to cause ill effects in humans as well as animals. Scientists believe the animals were made to feel uncomfortable by the positive ions, leading them to avoid the area. They are thought to have escaped to lower ground, where the air was less ionized. The findings may help experts develop better short-term seismic forecasts.

5 . Philosophers have a bad reputation for expressing themselves in a dry and boring way. The ideals for most philosophical writing are precision, clarity, and the sort of conceptual analysis that leaves no hair un-split.
There is nothing wrong with clarity, precision, and the like — but this isn’t the only way to do philosophy. Outside academic journals, abstract philosophical ideas are often expressed through literature, cinema, and song. There’s nothing that grabs attention like a good story, and there are some great philosophical stories that delight and engage, rather than putting the reader to sleep.
One of the great things about this is that, unlike formal philosophy, which tries to be very clear, stories don’t wear their meanings on their sleeve — they require interpretation, and often express conflicting ideas for the reader to wrestle with.
Consider what philosophers call the metaphysics (形而上学) of race — an area of philosophy that explorers the question of whether or not race is real. There are three main positions that you can take on these questions. You might think that a person’s race is written in their genes (a position known as “biological realism”). Or you might think of race as socially real, like days of the week or currencies (“social constructionism”). Finally, you might think that races are unreal — that they’re more like leprechauns (一种魔法精灵) than they are like Thursdays or dollars (“anti-realism”).
A great example of a story with social constructionist taking on race is George Schuyler’s novel Black No More. In the book, a Black scientist named Crookman invents a procedure that makes Black people visually indistinguishable from Whites. Thousands of African Americans flock to Crookman’s Black No More clinics and pay him their hard-earned cash to undergo the procedure. White racists can no longer distinguish those people who are “really” White from those who merely appear to be White. In a final episode, Crookman discovers that new Whites are actually a whiter shade of pale than those who were born that way, which kicks off a trend of sunbathing to darken one’s skin-darkening it so as to look more While.
Philosophically rich stories like this bring more technical works to life. They are stories to think with.

One morning this summer holiday, I was running on the road when I saw an elderly foreign lady waving her phone at me, speaking to me in a foreign language. Obviously, she didn’t speak English at all. When I listened to her more carefully, I found she was speaking German. She was clearly lost and trying to walk to the house where she lived. She showed me screen shots of maps on her phone as if she wanted me to help her find her way home. Actually, I learned some German in my spare time because our school will have German classes the next term. However, I was so poor at it that it was almost useless in practice.
I studied nearby and I knew my classmate, Lisa, who was good at speaking German. So I decided to telephone her. “Hi, Lisa. I came across a German lady. Do you have time to come and act as a translator now?” I said and then sent her my location, Unfortunately, Lisa answered, “Sorry, Belle. I’m shopping now. I can reach your place in about half an hour.” Hearing that, I had to tell her that I could manage myself.
Suddenly, an idea flashed through my mind. I downloaded a translation app and used the voice function to translate what the lady said into English. Just in this way, I learned that she came here to visit her daughter who was new to the city to teach. And I also determined the address she needed to get to. It was not far from here to her house, so I offered to walk with her to her destination. She was greatly grateful to me and kept saying sorry for taking my time.
When we got to the house, her daughter just came back. She was as touched by my kindness as her mother. I kept reminding her that it was no trouble for me, and that I only intend-ed to make sure her mother got there safely.
Walking with the lady was more rewarding than running alone. Despite having to rely on technology to communicate due to the language barrier, I felt lucky to have been able to help her. When I left, I couldn’t wait to share the wonderful experience with Lisa.

One day, while Sutter surfed the Internet watching some videos of cute animals with his mom, he came across a story posted by the local animal shelter (收容所). It explained that there was a cat, which was named Hazel by the workers, living in the shelter and needing help.
The workers found the cat at a transfer station where garbage and other waste are sorted. At first, the workers thought Hazel was just looking for food. But they later discovered that the back legs of the cat were injured. What was worse, after a physical examination, they found the bones of the cat were broken and that necrosis — meaning the death of cells in some part of the body — had set in. The workers thought Hazel would need surgery (手术) to get better. So they called on the community to raise money for the cat.
That was when Sutter got to work. After he knew the story about the poor cat in his community, the nine-year-old cat lover said to his mom,“I just can’t stop thinking about the cat. It is in urgent need of surgery. I want to raise money to help the cat.”Hearing those words, Sutter’ s mother was happy that her son was a kind-hearted boy and decided to help him.
Then Sutter came up with a good idea: making use of the power of cinnamon buns ( 肉桂卷). He knew if there was anything that could get the community members to empty their pockets, it would be this sweet treat: cinnamon buns. Then he and his mom started baking cinnamon buns, and his mom posted Sutter’s efforts on a social media page. Knowing Sutter’s good intention, the whole community reached out and donated money to Sutter. Finally, Sutter was able to raise $850 in total. Then Sutter and his mom gladly went to the animal shelter and dropped the money there.

________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________I’m smaller than everyone else my age. When I walk in the halls at school, I have to squeeze in between the bigger kids to get by. At the playground, sometimes even little kids try to boss me around. Mia, my best friend, is so tall that when she walks, I have to jog to keep up with her.
I used to try to make myself taller whenever I could. My posture was perfect, straight as an arrow. I hung from the tree in our backyard to stretch out my arms and legs. I even ate all my vegetables. Every day I measured myself, but I was the same height every time. Frustrating!
“Don’t worry,” Mom always said. “Being small has its advantages.” “Really? I could never notice any.”
One day, Mrs. Alvarez announced to the class that we’d be putting on a spring play. I practiced all the lines. But at the audition (试演), when I walked up to the stage, Mrs. Alvarez cried, “You’ll be perfect as the elf (小精灵)! You’re just the right size for the costume.” I even never got a chance to deliver the practiced lines. Back home I grumbled (咕哝) to mum that I was made an elf. But she bet I would be the best elf. To please her, I went to rehearsals (排练), though I only had two lines.
Mia got the lead role-a girl wandering through a magical fairy forest in search of her lost dog. In the last scene, she finds a box under a giant mushroom, and when she opens it, her dog jumps out. Mrs. Alvarez’s dog, Prince, played the dog role. She brought him to all the rehearsals, and when he wasn’t onstage, we got to play with him, but he seemed to like me best.
The night of the show, my first line came early, “Let’s ask the Fairy Queen!” Since my only other line was toward the end, I waited offstage, playing with Prince.

When two-year old Frankie-Rae Hockney took her first shaky steps across the livingroom, her mother cried. Although watching a child walk for the first time is an exciting moment for any parent, for Mary-Ella Tuppenney-Hockney it was a milestone she neverthought her daughter would meet.
Frankie-Rae was born with a rare chromosomal anomaly (染色体异常) called 17p 13.1 microdeletion syndrome, of which there are only 21 known cases. Doctors explained that they only had five different case studies who had the condition and so there were lots of uncertainties about her future. As a result, when she was born, Mary-Ella, 36, and dad Ben Hockney, 37,were warned that she might never walk or talk. They both broke down in tears, not knowing what life would hold for their daughter.
Mary-Ella is a dance teacher and she runs her own dance school in Oxfordshire and so dancing is a huge part of their lives. So she thought it was heart-breaking to think that Frankie-Rae wouldnever be able to be part of that. However, Frankie-Rae quickly beganseeing experts in occupational health. Despite all her problems, she grew into such a happy, smiley little girl who loved listening to music and waving (挥舞) along to it.
“Because she couldn’t walk as she got bigger, we needed a special pushchair and the one available on the NHS wasn’t suitable for her needs,” Mary-Ella explains. Fortunately, the Carter Trust stepped in to give Frankie-Rae one that worked. It meant her parents could take her shopping with them on weekends and out to the park. It made such a huge difference to her and the family. But Mary -Ella felt guilty for taking the money from the charity.
That’s when Frankie -Rae’s elder sister Georgie-Ellyn, eight, came up with the idea of fundraising (募捐) for the charity that helped them. As a result, the family got together, organizing some activities such as selling second-hand clothes and books. They also held aparty inviting those who cared for the charity.
