2 . Can robots paint? There’s research out there that shows they can be programmed to. The study “Region-based approaches in robotic painting” looks at how paintings can be copied using robots.
Using e-David, a painting robot developed at the University of Konstanz, researchers look at the use of stroke-based rendering (基于笔触的渲染) in copying art, whose aim is to copy human painting. However, they highlight that the robot sometimes struggles with stroke-based rendering. If the machine used to copy brush strokes runs into an error, it is unable to correct it in the same way that humans can. So the researchers apply “structured regions” in robot-based painting to reduce errors, helping to break up images into elements that can be painted individually to recreate the entire piece.
There’s another painting robot called the Pankraz Piktograph which seems to do a pretty good job at capturing faces. The operation of the Piktograph is very simple: you stand in front of the machine, look into the camera and take a photo. If you like what you see, the robot will then begin to draw it on a piece of paper. It does this using two human-like arms which are made from lightweight metal and driven by two engines. An ordinary ballpoint pen is held in a spring-loaded (装着弹簧的) carrier, which provides just enough pen-to-paper pressure to reliably draw lines without lifting off or destroying the paper.
Inside, the Piktograph is powered by a Raspberry Pi 3, which runs a rather difficult procedure to generate an image. The maker’s paper goes into quite some detail to explain the process, which uses Canny edge detection to create an outline drawing, and then fills in the empty bits to create bright and dark areas.
A certain amount of noise and wiggles (摆动) will be added to the lines to give them a more handmade feel, and the resulting drawing is divided into continuous lines for effective drawing by the machine.
Looking at the technicalities of painting with robots can help to create new tools for artists. This makes it an interesting area to keep an eye on in terms of art and technology.

4 . Some researchers from the London School of Economics, Oxford University and University College London carried out a research on the Exploring What Matters course. The course is taught throughout the country and is run by volunteers, who have no formal training but bring people together to explore “the things that really matter in life”.
The study found that satisfaction levels of those taking part increased by one point, increasing from 6.4 out of 10 to 7.4 after the course. Researchers said that this increase was greater than the boost people would get from being partnered rather than single (+0.59), and being employed rather than unemployed (+0.7).
So far, more than 6,000 people in the UK have taken part in the eight-week course. People involved in the course learn how to cultivate (培养) happiness by taking positive action in their daily lives. They also learn how to have better relationships and create stronger communities.
“I was quite sceptical,” said Jo Newstead, are tired health worker in London. “But I really enjoy it. There are nice people from all different backgrounds and we usually have a full discussion. It has made me focus on what I can do to help improve things for myself and for others.“
Mark Williamson, director of Action for Happiness, was not surprised by the study’s results. “This new research backs up what hundreds of people have already told us: taking part in these groups is life-changing,” he said. “But the thing we’re most excited about is that people coming out of this experience not only feel better about themselves, but also feel more connected to others and want to do more for others,” he added.

6 . It was the winter when I taught in a small country school on the west coast of Vancouver Island. I had three grades of little people in my class, all beaming with the desire to learn all they could. One little boy named David from my grade one class wanted to learn more than all the others. His round swollen face would smile up at me, reminding me over and over of his disease—leukemia. More often than not, he would be missing from our classroom for rounds of treatments.
All of us were so pleased, then, to have that happy little boy with us for Christmas. We decorated our classroom, practised for the concert, and prepared Christmas stories to share.
Two days before school let out for the three-week Christmas holiday, I read a story to the class. It was the story of “The Littlest Angel”. This little angel had an awful time in heaven. He could not adjust to the routine. He was always in trouble, bumping into other angels, tripping over clouds or dropping his halo. Nothing seemed to make his time easier until one celestial day an archangel suggested that the little angel take some items with him. Just a few things to remind him of his good old days, which might be of some help.
As I read the story, a complete silence fell over the class as each child became more involved in the plight of the angel. Everyone was sympathetic for his misfortune, including David.
The following day during our regular show-and-tell time, holding a small wooden box, David began his sharing, “This is my first tooth,” he explained. “This is a ribbon from my sister’s hair, and this is my puppy’s collar. My dad gave me this old key. My mom says this big coin is for good luck.” Even before he told us the purpose of the box, we all seemed to know. Shiny tears went dot-to-dot down the faces of the other children. The rest of the day witnessed all of us carefully preparing items to fill David’s wooden box.
When the holidays came to a close, we all returned to our class—all except David. He had got a good chance and left for a big city to get better treatment, clutching the wooden box that held his hope and memories, and ours.

7 . What does it take to graduate from university? Some papers or high scores in exams? Well, these are not enough if you are a student at Tsinghua University. According to a new rule of the university, students must prove (证明) themselves in the swimming pool. They need to pass a swimming test of at least 50 meters, and those who fail the test will be required to take a swimming course throughout their school years. By the time they graduate, they will have known how to swim; otherwise they can’t graduate with their bachelor’s degrees (学士学位).
The news made waves in Chinese social media (媒体). Some people praised the university for requiring a necessary skill that can save lives, and they also believed that the rule would help improve students’ health. However, others questioned if it was fair to expect those who come from inland cities (内陆城市) to be able to swim.
In fact, this is not a new rule. Tsinghua University first made swimming a requirement in 1919 but later gave it up because the number of students became too large and there were not enough swimming pools in the school for them to learn swimming.
Anyway, it is still good news that Chinese students’ health has become more and more valued. Why not just take this chance to learn one more life-saving ability?

8 . Dry lightning(雷电)can still be harmful even when conditions aren’t so dry, said a study published in Geophysical Research Letters last month. Dry lightning during little to no rainfall was previously thought to cause wildfire danger only with less than 2.5mm of rain in a day. A Washington State University-led study of wildfires in the US West found dry lightning caused wildfires despite up to 7.7 mm of rain.
“The rainfall amounts we recorded should help provide a better understanding of just how much rain can cause a fire risk,” said Dmitri Kalashnikov, lead author of the study.
The researchers analyzed(分析)cases on more than 4,600 naturally caused fires from 2015 to 2020. They matched 3,726 of those to the lightning strikes that likely started them with the help of National Lightning Detection Network.
The study found that 15.3% of those were holdover fires which burn without smoke, bringing about over a hundred fires each year. Analyzing the rainfall amounts around the time of the lightning strikes showed greater rainfall than previously thought among the earlier found fires ranging from 1.7 mm to 4.6 mm.
While humans still cause most fires either by accident or on purpose, lightning-caused wildfires burn the most areas. Nearly 70% of the wildfire-burned land in the West was from lightning-caused fires according to the study. For example, the largest wildfire burn area in California history took place in August 2020 after dry lightning caused many wildfires at once.
Dry lightning can also start wildfires in places that are hard for firefighters to reach. This study found the places where holdover fires happened repeatedly were in the forested mountains of the Southwest as well as the middle and southern Rocky Mountains. Holdover fires cause the problem because they are so hard to notice.

There was a girl called Cary, who was a new student in Esmarth Vil, a primary school in a small town.
She was the most hardworking girl at her school. Her marks were higher than the others. She was the best, but nobody wanted to be her friend. Her classmates didn’t want to play with her and some even laughed at her. Cary’s teacher Jared didn’t know that.
One day, Jared set an exam and Robert, a boy who was the king of all the students, signed his exam paper using Cary’s name, and changed Cary’s name for Robert’s quickly after Cary handed in her paper. It wasn’t noticed by anybody. When Jared returned all the exam Papers, everybody was shocked. Cary failed the exam, but the others seemed to be happy with that.
The next day, when Cary arrived at school, all the children wanted to be with her and invited her to play with them. Although Cary was surprised, she was happy to play with the other children. During their fun time, Jared suddenly appeared to inform Cary that there had been a mistake, and she hadn’t failed.
Jared explained to the students what had happened and punished Robert. After that, they all stopped playing with Cary again.
Cary couldn’t stop crying this time and ran to ask her teacher why she couldn’t make friends with good school performance.
