2 . Researchers have developed a robotic sensor that combines artificial intelligence techniques to read Braille (盲文) at speeds roughly double that of most human readers. The research team, from the University of Cambridge, used machine learning algorithms (算法) to teach a robotic sensor to quickly slide over lines of Braille text.
The robotic sensor the researchers used has a camera in its “fingertip”, and reads by using a combination of the information from the camera and the sensors. “This is a hard problem for roboticists as there’s a lot of image processing that needs to be done to remove motion blur (模糊), which is time and energy-consuming,” said Parth Potdar from Cambridge’s Department of Engineering.
“There are existing robotic Braille readers, but they only read one letter at a time, which is not how humans read, ” said Potdar. “Existing robotic Braille readers work in a static way: They touch one letter pattern, read it, pull up from the surface, move over, lower onto the next letter pattern, and so on. We want something that’s more realistic and far more efficient. ”
The team developed machine learning algorithms so the robotic reader would be able to “deblur” the images before the sensor attempted to recognise the letters. They trained the algorithms on a set of sharp images of Braille with fake blur applied. After the algorithms had learned to deblur the letters, they used a computer vision model to detect and classify each character.
Once the algorithms were incorporated, the researchers tested their render by sliding it quickly along rows of Braille characters. The robotic Braille render could read 315 words per minute with 87% accuracy, which is twice as fast and about as accurate as n human Braille reader.
“Braille reading speed is a great way to measure the dynamic performance of tactile(能触知的)sensing systems, so our findings could be applicable beyond Braille, for applications like detecting surface textures or slippage in robotic manipulation,” said Potdar.
In the future, the researchers are hoping to scale the technology to the size of a humanoid hand.

4 . Lexi is just a little girl from Canada who found herself in a heart-stopping situation. It started off as a normal car trip. Angela Shymanski, Lexi’s mom, was at the wheel, navigating the tricky roads of the Rockies with her daughter Lexi and her baby Peter in the car. An unexpected animal ran into the road. Angela swerved (突然转向) to avoid the animal. Unfortunately, their car was off the road, falling down a steep embankment (路堤).
The crash was nothing short of terrifying. Angela ended up with a broken back. She was unconscious, and unable to help her babies. Meanwhile, baby Peter’s cries echoed in the chaos. But Lexi, only five years old, didn’t freeze. Instead, she showed courage that would leave many grown-ups in awe.
She quickly jumped into action. The little girl, without even shoes on her feet, wrestled free from her seatbelt and climbed the 40-foot embankment. Once she reached the top, Lexi did everything she could to flag down a passing car in order to get help for her mom and brother.
Lexi’s insistence finally paid off. A car stopped, and the people inside didn’t hesitate to help her call for emergency services. When the paramedics (护理人员) arrived, they found Angela in a severe state, and her heart had stopped. Thankfully, they managed to bring her back.
Lexi’s dad, reflecting on the incident, couldn’t help but be amazed by his daughter’s bravery. He stressed how important it is for kids to be prepared for emergencies, shocked at how Lexi remembered and acted on what she had been taught. It’s a powerful reminder of what kids can do when push comes to shove.
And Lexi’s heroism didn’t go unnoticed. She was awarded a Bronze Medal for Bravery by the police. But for the Shymanskis, the real prize was being back in each other’s arms, safe and sound.

Brad Howard, a Texas father, had enough of his son’s disruptive (扰乱性的) behavior in physics class. Despite multiple warnings and complaints from the teacher about his son’s excessive (过多的) talking, the situation didn’t improve.
So, Brad decided to take matters into his own hands and gave his son, Bradley, a final warning. Brad made a bold promise to his son, saying, “Hey, if we get another call, I’m going to show up in school and sit beside you in class. ”
The 17-year-old Bradley probably thought his dad was just bluffing (唬人) and continued his chatty (爱闲聊的) ways. But when Brad received another email from the teacher, he knew he had to follow through with his threat.
On the morning of the important day, Brad’s wife woke him up and said, “Brad, it’s time for you to go to school. ” It struck him what he had said. He just couldn’t but a bit regret, “Oh, no, what have I done? ”
Despite his unwillingness, Brad was determined to keep his word and headed to his son’s high school.
The sight of Brad sitting next to Bradley in class was a source of amusement for Bradley’s friends, who found the situation ridiculous. Bradley, on the other hand, was less than thrilled.
He couldn’t believe that his dad had actually gone through with his threat, The embarrassment of having his own father sitting beside him in class was enough to make him regret his behavior. As the class started, Bradley could feel all eyes on him and his dad. He could sense the judgment and the whispers from his classmates.
“Hey, Bradley, it looks like your dad is really serious about this, ” one of his friends whispered across the hallway, trying to hold back a laugh.
“Yeah, this is so embarrassing, ” Bradley whispered, his cheeks turning a deep shade of red.

For the history of life on Earth, organisms have relied on the light of the sun, moon, and stars to find their way and schedule their lives. While the beginning of electric lighting in the late 19th century may have benefited humans, it has caused problems in the natural world. Among the impacts of artificial light at night(ALAN), light pollution lures migrating birds to cities with shocking consequences, contributes to the alarming decline in insect populations, and convinces sea turtle babies to amble(缓行)away from the water instead of towards it.
Now, a new study from the University of Plymouth adds another disappointing finding about how ALAN is affecting the creatures with whom we share the planet: Light pollution from coastal cities can trick corals(珊瑚)into reproducing outside of the optimum times when they would normally reproduce.
Using a combination of light pollution data and spawning(产卵)observations, researchers were able to show for the first time that corals exposed to ALAN are spawning one to three days earlier and closer to the full moon compared to those on unlit corals. “That shift may reduce the survival and fertilization success of gametes(配子)and genetic connectivity between nearby lit and unlit coral systems,” they explain.
“Corals are among the most biodiverse, economically important, and threatened ecosystems on the planet,” write the authors of the study.
“Climate change has led to mass bleaching(褪色)events. Habitat destruction, fisheries, and pollution have reduced corals substantially since the 1950s,” they write, adding, “The complete loss of corals is anticipated over the next 100 years.”
If we want to reduce the harm ALAN is causing, we could perhaps look to delay the switching-on of night-time lighting in coastal regions to ensure the natural dark period between sunset and moonrise when coral reproduction remains undisturbed.

Ever since I came to work in my present company five years ago, I have heard about a small restaurant nearby called Love Dad. Everybody believes that it is owned by somebody’s loving dad. The restaurant does give the diners a sense of home. The furnishings are homely, with dining areas looking like family dining rooms. Best of all, they have hand-drawn cards, which diners can take away with them when checking out. The restaurant doesn’t have a menu. You never know what will be served until you come to its door with a “served today” notice hanging to it.
Whenever I pass by, I just can’t help entering to enjoy the homely atmosphere. It’s a reminder of my own home and my dad, who will prepare a great dinner for the family every day. Dad is a manager in a construction company and a great cook at home and not only a great cook. He is the kind of hero-like father at home, who can fix everything in the home and deal with all problems. As my parents live in another city, this small homely restaurant is where I choose to go to comfort my homesickness.
Curiosity about whose dad the owner of the restaurant is has always been there among my workmates who are its regular customers but it seems that nobody has a clue. It doesn’t matter much as all of them can get a taste of home there.
Last month, when I was home for the Christmas break, my parents talked to me about their plan for retirement and I mentioned the restaurant Love Dad to them. We all thought it would be great if Mom and Dad could join the restaurant in some way. They asked me about the exact location of it and decided to deal with the matter themselves.

10 . The Robbers Cave Experiment was part of a series of studies conducted by social psychologist Muzafer Sherif and his workmates in the 1940s and 1950s. The researchers divided boys at a summer camp into two groups, and they studied how conflict developed between them. They also investigated what did and didn’t work to reduce group conflict. The boys were left in the dark about the experiment.
In the 1954 study, boys who were approximately 11~12 years old thought that they were participating in a typical summer camp, which took place at Robbers Cave State Park. However, the campers’ parents knew that their children were actually participating in a research study.
The boys arrived at the camp in two separate groups: for the first part of the study, they spent time with members of their own group, without knowing that the other group existed. The groups chose names, the Eagles and the Rattlers.
After a short period of time, the boys became aware of the existence of the other group and began to speak negatively about the other group. Then the researchers arranged a competitive tournament between the groups, consisting of games such as baseball and tug-of-war and the relationship between the two groups quickly became tense. The campers rated their own group more positively than the rival (对立) group.
To determine the factors that could reduce group conflict, the researchers first brought the campers together for fun activities such as having a meal or watching a movie together. However, this didn’t work to reduce conflict.
Next, Sherif and his workmates tried having the two groups work on common goals. For example, the camp’s water supply was cut off purposely by the researchers, and the Eagles and the Rattlers worked together to fix the problem. Working on shared goals eventually reduced conflict and friendships began to form with members of the other group. In the end, some of the campers requested that everyone from both groups take the bus home together, and one group bought drinks for the other group.
