A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love, (早恋) may bring stress for young people and can lead to depression. The study shows that girls become more depressed than boys, and younger girls are the worst of all.

    The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study, even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won't tell that to their parents.

    Dr Marianm Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendships and a strong sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.

    Parents should watch for signs of depression-eating or mood changes-and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity gives us a chance to avoid its bad side effects.

    Indian-origin Anvitha Vijay has given a new meaning to the phrase “age is just a number”; she has proved that achievements and knowledge follow passion and not just age and experience.

    Vijay, who lives with her parents in Melbourne, Australia, at the age of seven realized that her piggy bank did not have enough money to hire a developer to make her an app, so she decided to teach herself how to code. With the help of YouTube videos, the young techie learned to code. For one entire year, she watched multiple coding tutorials on the web and became a programmer herself.

    Vijay's inspiration for developing the apps was her little sister, who was still learning to talk. Therefore, Vijay developed an educational app for children that were her sister's age. The app is called Smartkins, which uses about 100 sounds and flashcards of different animals that help children learn and identify. Later, Vijay developed a similar iOS app for children to identify and learn colors. Each app has been downloaded thousands of times.

    Anvitha's skills won her a scholarship to attend a big tech conference hosted by Apple in San Francisco, California. There, she got tips from the pros. She went to workshops where she learned about the latest software for app building.

    All that training led to an idea for a third app. This one, called GoalsHi, inspires kids to practice good habits. Users are rewarded for achieving goals, such as eating their vegetables or practicing piano. Anvitha says the rewards are like getting a sticker for a job well done.

    Anvitha's goal is to continue creating technology that helps kids learn while having fun. But even more important to her is that the world sees the power of technology in kids' hands. “The more training we get in tech at an early age,” she says, “the better chance we have of becoming creativity champions who will one day change the world.”

    It doesn't matter when or how much a person sleeps, but everyone needs some rest to stay alive. That's what all doctors thought, until they heard about AI Herpin. AI Herpin, it was said, never slept, Could this be true? The doctors decided to see this strange man themselves.

    AI Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Herpin sleeping, In fact, he did not even own a bed. He never needed one.

    The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They found only one answer that might explain his condition. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason? No one could be sure.

    Herpin died at the age of 94.

China's Tianwen 1 Mars probe (探测器) conducted its fourth orbital correction on Friday evening, as the spacecraft makes ready for its arrival in orbit around Feb. 10, according to the China National Space Administration.

The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan, one of the greatest poets of ancient China. In Tianwen, this name conveys the Chinese nation's steady effort in pursuing truth and culture of exploring nature and the universe. CNSA also unveiled (发布) the logo of China's planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.

Tianwen I has flown for 197 days and more than 465 million kilometers on its journey to the planet. It is now around 184 million km from Earth and I. I million km from Mars. Depending on the two planets' orbits, Mars is between 55 and 400 million km from Earth. Mars probe Tianwen I is seen in its first selfies in space on Oct. 1, 2020. The administration also published a black-and-white picture of Mars taken by Tianwen I, the first snapshot (抓拍的照片) from the Chinese craft.

Tianwen I, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

A successful landing would make China only the second nation to place a spacecraft on the Martian planet. China would also be the first to successfully orbit, land and deploy (部署) a vehicle in the same mission. According to experts, searching for signs of life on Mars will be the first and foremost scientific goal. China is open and inclusive in the development of its space technology not least because it believes that the exploration of outer space should help build a community with a shared future for mankind.

I was first going into this final day, the Junior Sled Dog Championship. We'd trained two years and wanted to beat Blake. I knelt down to pat Kenai and my hands 1 from nerves and excitement. Kenai tipped up his face to lick my chin. "You are 2 , aren't you?"

Just before the countdown started, Blake shot me a 3 grin, hands trembling too. Then I heard, "Go!" 4 I could yell "Hike!", Kenai leaped forward. The rest of the dogs 5 after. We started last. We flew down the long hill. Then we 6 a corner. I leaned to keep the sled steady. Kenai saw Blake's team before I did. His tail flew up, and he 7 . Seeing his tongue still flopping forward, I let him go all out. We closed the 8 . A bridge later, we inched closer. On the next hill, Kenai drew even with Blake's sled and then we passed it.

9 our sled hit a branch. The runners caught. I lost my 10 and fell off the sled. Witnessing the sled come to a stop, I struggled through the deep snow to Kenai. I 11 . His shoulder was bleeding.

"Kenail! No!", My voice came out a howl. Kenai 12 to stand. He looked at me, his blue eyes 13 to keep on. He would do it, too. For one frozen moment I saw myself on the winner's stand with the trophy. But no, I bent and gently 14 Kenai in a blanket.

The race vet examining Kenai, I watched Blake accept the trophy. Kenai squirming (扭动) in my lap, I leaned over upon him. Just at that moment, I felt a warm tongue on my wet cheek. I smiled and realized that I had the 15 that really counted.
