2 . French children 15 and under will no longer be allowed to bring smart devices to school. Lawmakers in France voted recently to ban all phones, tablets, and other Internet-connected devices from school grounds. The ban will start in September, “These days, the children don't play at break time anymore,” Jean-Michel Blanquer, France's education minister, said. “They are just all in front of their smartphones, and from an educational point of view, that's a problem. Some strict measures must be taken immediately.” A 2010 law bad already banned smartphones during "all teaching activity" in France. But the new rules say smartphones and tablets are not allowed even during breaks. Students who bring these digital devices to school have to keep them in their backpacks and turned off, If they want to call their parents, schools will help. However, the new law doesn’t forbid students to turn to them during extra-curricular activities. It also makes an exception for disabled students.

Alexis Corbiere is a French politician. He said the effort to make such a law should have been put to something else because teachers have already carried out this rule so far. “I don't know a single teacher in this country that allows the use of phones in class and in school, ” he told French news channel BFMTV.

How about smartphones in American schools?According to a study by the National Center for Education Statistics, about 66% of public schools banned devices in 2019, which was down from 91% in 2009. Why the change? Liz Kolb, a professor at the University of Michigan School of Education, said that parents are concerned about security in schools. "In the rare case that something may occur, " she said, "the belief by some parents is that a cell phone could be a useful tool for safety."

4 . Narasimha Das is on his way to feed 169,379 hungry children. Das is in charge of a kitchen in Vrindaban. The town is about a three-hour drive from India’s capital, New Delhi. Das gets to work at 3:00 a.m. Thirty workers are already working to make tens of thousands of rounds of bread. It will be brought to 1,516 schools in and around Vrindaban.

A Growing Problem

Going to school is difficult for more than 13 million children in India. They must go to work instead, or go hungry. That’s why India began the Mid-Day Meal Scheme, the largest school-lunch program in the world. A free lunch encourages children to come to school and gives them the energy they need for learning. The program began in the 1960s.

The kitchen in Vrindaban is run by the Akshaya Patra Foundation. It is one of the lunch program’s biggest partners. “Just $11.50 can feed one child for an entire year,” said Madhu Sridhar, president of the Akshaya Patra Foundation.

Lunch Is Served!

The Akshaya Patra food truck arrives at Gopalgarh Primary School. Since the program started, the number of underweight children has gone down. The children get foods they need — as long as they finish what’s on their plates.

5 . Will your kids love your favorite childhood reads? Let’s get to it: Five Little Peppers and How They Grew. I’m reaching way back with this one (1881), but after all, who doesn’t love a good rags to-riches story?

Oh, those little Peppers. How well I remember Phronsie, Ben, Polly, Joel and Davie, and how hard they worked in the little brown house to help their poor mother, Mamsie. My kids are not yet at an age when they realize just how poor the Peppers are. But my kids are as drawn to this story as I was as a child. And I am not the one to turn down an opportunity to share an example of children gladly helping their mother.

I’m not reaching back quite as far with 1943’s Cherry Ames, Student Nurse by Helen Wells, but convincing my kids that once it wasn’t easy for nurses to wear caps and dresses. When I was little, I couldn’t get enough of Cherry’s adventures. How pioneering Cherry was! She had a job when there were few jobs available to women, she never got married, and she solved mysteries when men couldn’t. Cherry always knew what to do. She was smart, pretty, strong and ambitious. I love her.

I know the time will come when my son asks, “Come on, Mom, Didn’t you read any books with men in them?” and I’ll have to answer honestly, “No. But maybe one day a few.”

The day will come when we can go back to the library and see what is new on the shelves, and that will be a great day. But for now, I plan not to let any book on our shelves go to waste. It may seem that reaching for a book that’s more than a century older than my kids is just as ambitious as reading Frankenstein, but I’m really confident, this time.

6 . Avi Loeb, a scientist, believes that we are not alone in the universe. The belief fits with Loeb’s alien (外星的) spaceship theory that at least one alien spaceship might be flying over the orbit (轨道) of Jupiter, which won the international attention last year.

Astronomers in Hawaii found the first known interstellar (星际的) object in late 2017. It was a bit of light moving so fast past the sun that it could only have come from another star. Almost every astronomer on the planet was trying to figure out how the object, called “Oumuamua” got to our far-away, part of the Milky way galaxy. “One possibility is that ‘Oumuamua’ is debris (碎片) from an advanced technological equipment,” Loeb said. “Technology comes from another solar system just showed up at our door.”

“‘Oumuamua’ is not an alien spaceship,” Paul Sutter, another scientist wrote. He suggested Loeb was seeking publicity. Most scientists think “Oumuamua” is some sort of rock. They think it could be an icy wandering comet.

Loeb says that “Oumuamua’s” behavior, means it can’t be a block of rock shaped like a long photo. He thinks it's more likely an object that’s very long and thin, perhaps like a long pancake or a ship’s sail. Loeb says that if someone shows him evidence that contradicts his beliefs, he will immediately give in.

Loeb believes himself a truth-teller and risk- taker in an age of very safe, too-quiet scientists. “The worst thing that can happen to me is that I would be relieved of my management duties, and that would give me even more time to focus on science,” Loeb says. He said he wouldn’t mind giving up all the titles he had and returning to the Israeli farming village where he grew up.

7 . Each year, the women of Olney and Liberal compete in an unusual footrace. Dressed in aprons (围裙) and headscarves, they wait at both towns’ starting lines. Each woman holds a frying pan with one pancake inside. At the signal, the women flip (轻抛) pancakes and they’re off!

This “pancake racing” tradition is said to have started on Shrove Tuesday, 1445, in Olney. Shrove Tuesday is the day before the Christian season of Lent (大斋戒) begins. During Lent, many people decide to give up sugary or fatty foods.

Legend says that in 1445, an Olney woman was making pancakes to use up some of her sugar and cooking fats before Lent. She lost track of time and suddenly heard the church bells ring, signaling the beginning of the Shrove Tuesday service. Realizing that she was going to be late for church, she raced out the door still wearing her apron and headscarf and holding her frying pan with a pancake in it. In the following years, the woman’s neighbors imitated her dash to church, and pancake racing was born.

The rules are simple. Racers must wear the traditional headscarf and apron. They must flip their pancakes twice - once before starting and once after crossing the finish line. After the race, there are Shrove Tuesday church   services. Then Liberal and Olney connect through a video call to compare race times and declare a winner.

In both towns, the races have grown into larger festivals. Olney’s festival is an all-day event starting with a big pancake breakfast. Liberal’s festival lasts four days and includes a parade, a talent show, and contests that feature eating and flipping pancakes. Although the women’s race is still the main event, both towns now hold additional races for boys and girls of all ages.

9 . It appears to fit with most people's experience: how Christmas seems to come around quicker every year? Questionnaires by psychologists have shown almost everyone feels time is passing faster now compared to when they were half or a quarter as old. Most strikingly, lots of experiment have shown that, when older people are asked to guess how long the time is, or to ‘reproduce’ the length of periods of time, they guess a shorter amount than younger people.

In 1877, Paul Janet suggested the proportional theory, where a child of 10 feels a year as I 10 of his whole life while a man of 50 as 1/50, so the subjective sense of the 50-year-old man is that: these are insignificant periods of time which gallop.

There are also biological theories. The speeding up of time is linked to how our metabolism (新陈代谢)gradually slows down as we grow olden Children's hearts beat faster than They breathe more quickly. With their blood flowing more quickly, their body clocks “cover” more time within the space of 24 hours than ours do as adults. On the other hand, older people are like clocks that run slower than normal, so that they lag behind, and cover less than 24 hours.

In the 1930s, the psychologist Hudson Hoagland found body temperature causes different perceptions of time. Once, when he looked after his ill wife, he noticed she complained he'd been away for a long time even if only away for a few moments. Therefore, Hoagland tested her perception of time at different temperatures, finding the higher her temperature, the more time seemed to slow down for her, and that raising a person's body temperature can slow down his sense of time passing by up to 20%.

Time doesn't necessarily have to speed up as we get older though. It depends on how live our lives, and how we relate to our experiences.

10 . The structure of DNA plays an important role in medicine and biology. But you may not know that its founder is a female scientist and goes through a lot on her way to make scientific research. Rosalind Franklin was born in London, England on July 25, 1920. On April 16, 1958, at age 38, she died from cancer. Franklin was responsible for much of the research and discovery work that led to the understanding of the structure of DNA.

Franklin was interested in science and attended one of the few girls' schools in London that taught physics and chemistry. When she was 15, she decided to become a scientist. Her father was decidedly against higher education for women and wanted her to be a social worker. Franklin's aunt decided to support her and she agreed to pay for her full schooling. Within weeks, Franklin's aunt got her mother to support her going to college also. Months later, Franklin's aunt and mother got her father to agree with it. Franklin was very excited that she was going to college and did a good job in her study.

After her graduation from college, Franklin started her research on DNA. However, there were so many quarrels in her life because Franklin and her research partner did not get along. Franklin and her partner's arguments set them back on the study of DNA quite a bit. At the time they were working against another pair to find the story of DNA. Because of Franklin and her partner's fights, another pair found the structure of DNA first and won the Nobel Prize for it four years after Franklin died. Many scientists felt sorry for her early death and thought that the winners had stolen her research about DNA.
