1 . A team at a US university trained an AI tool to examine 60,000 fingerprints to see if it could work out which ones belonged to the same individual. The researchers claim the technology could identify, with 75-90% accuracy, whether prints from different fingers came from one person.
But they are not sure how it works. “We don’t know for sure how the AI does it,” admitted Prof Hod Lipson, a roboticist at Columbia University who led the study.
Graham Williams, professor of forensic science (法医学) at Hull University, said the idea of unique fingerprints had never been set in stone. “We don’t actually know that fingerprints are unique,” he said. “All we can say is that as far as we are aware, no two people have yet to show the same fingerprints.”
The results of Columbia University’s study could have the potential to impact both biometrics and forensic science.
If, for example, an unidentified thumb (拇指) print is found at crime scene A, and an unidentified index (食指) fingerprint at crime (犯罪) scene B, the two could not currently be forensically connected to the same person — but the AI tool could be able to identify this.
The Columbia University study will be published in the journal Science Advances on Friday. But a pair of twins in Cheshire might be ahead of everyone. Their grandmother Carol told the BBC her two grandchildren can open each other’s iPhones using their own fingers.
“They showed me on Christmas day,” she said. “We were told they were identical when they were born but I can tell the difference between them as they’ve got older.”She claimed that her grandchildren can also bypass the handsets’ facial recognition feature.
Fingerprints are formed before birth. Research published last year suggested the genetic process behind them may be similar to the way animals like zebras and leopards get their markings.

2 . If you have a chance to go to Finland, you will probably be surprised to find how “foolish” the Finnish people are.
Take the taxi drivers for example. Taxis in Finland are mostly high-class Benz with a fare of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to, and then walk off without paying your fare. The driver would not show the least sign of being annoyed and worried.
The dining rooms in all big hotels not only serve their guests, but also serve outside diners. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals. The most they would do to show their good faith is to wave their registration card to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends to dine free of charge.
The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed with the boss on the pay. From then on, they just say how many hours they have worked and they will be paid accordingly.
With so much carelessness in everyday life, surely Finland must be a heaven to those who love to take “petty advantages” (小便宜). But the strange thing is, all the taxi passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. And workers always give an honest account of the exact hours they put in.
As the Finns always act on good faith in everything they do, living in such a society has turned everyone into a real “gentleman”. In a society of such high moral practice, what need is there for people to be on guard against others?

3 . When Senait Lara, a 28-year-old video producer, was questioned by her friends about her lack of communication in their group chat, the blames were as follows: she only caught up every few days; when she did, it was hardly an interaction — Lara spent time “liking” messages instead of responding with words and sometimes she would never respond at all. Lara didn’t deny it. She knew she sometimes preferred to completely avoid her phone rather than deal with a large number of requests. Actually, in person, Lara felt comfortable talking with people, but when communication came down to a text message or an email, she wanted to tap out.
While social media and messaging apps keep us more connected to each other, many younger users are finding themselves tired out from receiving constant notices and carrying on conversations that can last all day. The after-effect? Delayed responses, forgetting to get back to someone entirely, and a need for frequent breaks.
In fact, a 2023 study exploring the effects of information overload and online conversation dynamics (动态) found that “over-exposure to information can suppress the possibility of response by overloading users.”
Smartphones have quickly changed into handheld storage units for our conversations, thoughts, music and everything else. That shift to feeling constantly attached to our phones as if they were a limb relates to the burnout, says psychologist Emily Balcetis.
As the pressure to be online and always available continues to grow in our society, in-person interactions provide far more real communication than digital ones. From body language to eye contact and all the other social clues that exist in real life that aren’t available in a text message, it’s far easier to be present when you’re face-to-face. As Balcetis notes, “At the end of the day, I think what we’re looking for is not more ways to stay connected, but higher quality ways to be connected.”

A.The need to take a break from digital devices. |
B.The pressure of always being available online. |
C.The importance of face-to-face communication. |

5 . As evening fell, five people moved nervously around a baby elephant. All the science, all the ideas leading up to this moment, checked out. But now, it was a question of practice: Would this baby elephant like the newly developed baby formula (配方)? Would her body react well to it?
The five people, keepers at Reteti Elephant Sanctuary, northern Kenya’s only elephant orphanage (孤儿院), held one another’s hands. They hoped that she would be healthy. As baby Sera gulped down one bottle after another, they smiled with relief. And in the days that followed, the weak two-week-old put on weight and had the strength to play with the other baby elephants at the orphanage.
The keepers celebrated the breakthrough. The formula was simple and the main ingredient (成分) of the new formula was easy to get: goat milk.
The team had been thinking about how to improve their milk recipe for a long time, says Katie Rowe, co-founder of Reteti, in the community-owned Namunyak Conservancy. The orphanage had used human baby formula since its establishment in 2016, but costs were high, cans had to be bought from foreign countries, and ingredients weren’t always natural. “I was looking at the ingredients, believing there were better choices out there,” Rowe says.
The new formula has also been a success for the Samburu community, which sells goat milk to the orphanage. Each morning, Stamen Lemajong’s family and others travel along tree-lined roads to sell more than 150 liters of milk to the orphanage. “We use the money from selling goat milk for everything the kids to school, paying hospital bills,” Lemajong says. “And in times of hardship last year, it has been a huge help. Then we could even buy food with it.”

6 . We’re getting more used to chatting to our computers and smart phones through all kinds of voice assistants.
Some think voice could soon become the main way to interact online. They believe online interaction would soon depend mainly on the spoken web.
Building the spoken web-web-to-voice and voice-to-web — is by no means an easy task. For software, to answer simple questions about the weather and play music for us is easy.
Using voice interaction makes people feel much kinder than surfing the net in the old way.
A.Yet who can use the spoken web? |
B.It is also possible to help teachers give lessons. |
C.But what are the challenges of moving to the spoken web? |
D.The voice of the assistant makes us feel like talking to a real person. |
E.Out of these voice assistants, Siri is the most well-known spoken web. |
F.The benefits of using voice obviously depend on the situation you are in. |
G.However, to have a conversation with users on different kinds of topics is a long way off. |
7 . While you may get flowers or a card from the one you love on Valentine’s Day, it can be hard to know how our four-legged friends feel about us.
Happy greeting
It’s great to be welcomed home by our pet and your dog isn’t doing this to show welcome to you;
When your pet chooses to look at you with soft, relaxed eyes, they trust you and are happy in your company, accepting you as non-threatening. And, it could be argued, that trust is the highest form of love.
Hugs (on your pet’s terms)
Your dog can choose to curl up wherever they like, so when they hug you, they are actively choosing you. This can range from full body hugs to them leaning into you to ask for some love. However, any hug must always be on your pet’s conditions and personalities.
Tail wagging
A wagging tail can display a whole range of emotions from your dog, but you’ll know it’s a sign of love when they treat you to a full body wiggle. Their tail will turn around in circular movements like helicopter propellers (螺旋桨).
Licking you
Your dog may lick you for a variety of reasons, but one of them is affection and love. They are ultimately seeking attention from you because they want to interact with you.
A.Soft eye contact. |
B.Cheerful and excited barking. |
C.Actually, it’s a sign that they are pretty happy to see you. |
D.In actuality, it’s a sign that they are hungry and eager for some treats. |
E.Some dogs will find having someone’s arms around them stressful and uncomfortable. |
F.Our cats and dogs can’t tell us how they feel, so what are the other signs that you share a special connection? |
G.This type of tail wagging is usually reserved for people that are special to them, and is mostly used when dogs see their owners. |
8 . The Benefits of Listening to Music
Whether you like Beethoven or Mozart, there is one thing I think we can all agree on: music makes life better.
Listening to music can reduce stress
A lot of us may turn to relaxing music when we are feeling stressed or tired. A recent research shows that slow, quiet classical music is suggested to have the most exciting effect.
Listening to music can improve your memory
The interesting part about the research is that it shows music helps your brain develop in many areas, one of the most important being your memory.
Do you work out? Have you always felt like you perform better when you listen to music? Strange as it might seem, there has actually been a lot of research done on this subject. And sure enough, one study shows that music can increase endurance (耐力) by 15%.
A.Listening to music can improve endurance. |
B.Listening to music can make you healthier. |
C.The followings are some benefits of listening to music for us humans. |
D.One theory is that listening to a classical piece helps you focus, which in turn allows you to persevere longer. |
E.One of my biggest regrets these days is that I never actually tried to learn to play the piano properly. |
F.So if you’re troubled by a bad memory, learning to play an instrument is something you should consider. |
G.So if you have a hard time dealing with stress, listening to some classical songs could be a good idea. |
9 . When looking at fashion shows or the latest magazine trends, you might think you’ve seen it all before. It seems that designers often revisit past concepts (概念). However, to glimpse the future of fashion, one must turn to the meeting point of fashion and technology, where innovative ideas are born.
For several years now, people have been talking about “wearable technology” as the next big development. You can already buy watches that do everything your smartphone can do, or glasses with computers that follow your eye movements and feed information to you as you walk around. But there’s much more to wearable technology than that.
Sports clothing is one of the areas. Runners already wear small computers on their wrists (手腕) that give them continuous information about how fast they’re running, how hard their bodies are working, and so on. Experts agree that it’s often sportspeople (usually young men) who are the first to take up new fashion ideas. Others then follow.
Women, it seems, are usually more interested in what clothes look like than what they can do, and technology has a part to play here too. Designers are making clothes that can change color with how you feel, or react to sound. And if you think that sounds unlikely, just think of all the things we accept as quite normal today that seemed impossible or silly only ten years ago.
The primary reason such items aren’t available in mainstream stores is their high cost. However, like all technological products, their prices are likely to decrease rapidly, as technological clothing doesn’t necessarily have to be costly.

10 . St. Patrick’s Day, Ireland’s National Day, is celebrated on 17th March every year, marking the anniversary of the day on which he passed away. St. Patrick is the most famous saint of Ireland. Born in Roman Britain, he was enslaved in Ireland at the age of 16, but he successfully escaped. Later, he returned to Ireland and brought his religious beliefs to its people.
On St Patrick’s Day, Irish families would traditionally attend church in the morning and celebrate in the afternoon. People would dance, drink, and feast on traditional meals of Irish bacon and cabbage. The Irish have observed this day as a religious holiday for over 1,000 years.
Interestingly, however, the first parade held to celebrate St Patrick’s Day took place not in Ireland but in the United States. On 17th March 1762, Irish soldiers serving in the English army marched through New York City. Along with their music, the parade helped the soldiers reconnect with their Irish roots, as well as with fellow Irishmen serving in the English army.
Over 100 St. Patrick’s Day parades happen across the U.S., with New York City and Boston hosting the biggest. In 1848, New York Irish Aid societies joined to create the official New York City St. Patrick’s Day Parade, the world’s oldest civilian (平民的) parade and the largest in the U.S. It draws over 150,000 participants and nearly 3 million spectators (观众), lasting over five hours. Boston, Chicago, Philadelphia, and Savannah also celebrate the day with major parades.
Today, people of all backgrounds celebrate St Patrick’s Day, especially throughout the United States, Canada and Australia. It is also celebrated in many other locations far from Ireland, including Japan, Singapore, and Russia.
