Look into hunters' eyes

    Have you ever been face to face with a cat or a sheep? If you have,you probably noticed that cats narrow their eyes to vertical (垂直的) slits (狭缝),while sheep have horizontal pupils (瞳孔).

     Why is the difference?

    Scientists from the Universities of California Berkeley and Durham in Britain may have the answer. Their research, published recently in the journal Science Advances, suggested that pupils' shapes could tell whether an animal is a hunter or gets hunted.

    The researchers took a close look at the eyes of 214 land animals.The challenge was to see if they could find a relationship between an animal's role in the food chain and the pupils' shapes.

    They found a pattern. Species with pupils that are vertical slits are more likely to be small ambush predators (捕猎者) – creatures that lie in wait for their lunch.In contrast,those with horizontal pupils are more likely to be plant-eating prey (猎物) species.

    Evolution chose the arrangement for a good reason.For hunters such as household cats,it appears that vertical pupils not only improve their ability to keep track of moving objects like mice,but also maximize (使最大化) their ability to judge the distances of the animals they hunt.

    However, an interesting discovery from the study is that the slit pupils are mostly linked to hunters that are close to the ground. Therefore, bigger cats who actively hunt down their prey, like tigers and lions, don't have slit pupils.

    On the other hand, for plant-eating prey animals, horizontal pupils give them a wider field of vision.When stretched (伸展) horizontally,the pupils allow for more light to enter from the front, back, and sides. Meanwhile, they also limit the amount of light from the sun above so the animal can see the ground better.“ Once they do find a predator,they need to see where they are running,” said leading researcher Martin Banks,a UC Berkeley professor of optometry (视光学).“They have to see well enough out of the corner of their eye to run quickly and jump over things.”

    But what happens when they bend down to eat? Researchers checked this by watching prey animals in the Oakland Zoo in California, US. They believe that when goats lower their heads to eat,their eyes rotate (旋转) to keep their pupils horizontal.

    So it seems that the eyes are indeed the window to the soul!

    Eight-year-old Owen Howkins suffers from growth delays(迟缓) and poor eyesight. This means that Owen needs a wheelchair to get around. Not surprisingly, he felt people were staring (盯着看) at him, and that made him very uncomfortable, so he became lonely and even stopped going outside of his house. That, however, was all before Haatchi came into his life!

    Haatchi had a very unlucky start to life too. Tied to a railway track when he was just five months old, the dog was hit by a train. The hit unjured his tail and a leg so badly that both had to be cut off. Taken to a rescue shelter(救助站), the dog would have probably been killed if his story posted on Facebook had not been seen by Owen's dad Will. He fell in love with Haatchi and decided to keep him, thinking that they were helping him. It turns out that it was Haatchi who helped them. By always staying at young Owen's side, he became the boy's best friend. Slowly Owen liked to go outside. Wherever he goes, the dog follows and protects him. Owen now proudly walks around the neighborhood, showing off his dog and telling anyone willing to listen, Haatchi's story.

    Haatch's positive influence on the young boy has not gone unnoticed. In October 2012, the International Fund of Animal Welfare presented him with a special award(奖). The amazing friendship between the two has also been shown in a touching short film called “A Boy and His Dog” by students from the filmmaking class at the University of Hertfordshire. It has won several awards and had almost 2 million views. British best-selling author Wendy Holden has also writtern about this touching friendship in a aheartwarming children's book, which was released on February 13th and had made Owen and Haatchi better known!

    There is always something that happens in the world that everyone fears will happen to their town, city or country: natural disasters. The scariest part of it is that no one will ever see it coming. Though technology helps us prepare, but it never actually tells the people when it's going to hit. It is always estimated but the result is never 100% accurate.

    However, that is not the point of this article. Two different natural disasters in two different parts of the world have happened in the past few weeks. One was a major flood that has hit Louisiana in the United States. The other was an earthquake that hit Amatrice, Italy. However, there is a major difference in the news coverage of the two tragedies.

    As for the flooding in Louisiana, it is reported that this disaster is the worst to hit the United States since Super-storm Sandy and it'll cost at least $30 million. In only the first couple of weeks, 13 people had died. However, like me, many people did not hear about this tragic event. I did not learn about it until about three weeks after it happened.

    In Italy, however, it covered all media instantly. The earthquake in Italy happened on Tuesday morning. That same day, I was on Twitter and that was all that was over the news feed. Every other post was about the earthquake. Some would have the opinion that Amatrice, Italy was one of the most beautiful towns in that country. I got in deep sorrow because there were more people killed in this quake than the flooding. So far, they have a total of 73 dead and over one hundred missing.

    I understand that technically the earthquake in Italy was worse than the floods in Louisiana. However, I believe that if a natural disaster happens, they all should be equally covered and taken equally seriously. We are one world united and should be there for all of the people who are in need of help. We may not be able to accurately predict disasters but, we can surely lend a hand out for the needy.

    Young people's mental health is of increasing interest and concern to researchers, policymakers, and families alike－but can treating teenagers' mental health problems also improve the wellbeing of their parents? New research suggests that it can. The study, conducted by Kelsey Howard, a doctoral candidate at Northwestern University, found that regardless of which treatment teenagers were using for their depression, the mental health of their parents improved too.

    Older findings say that there is a link between mothers' depression and major depression in their teenagers, although it seems not to be biological. However, the latest research suggests that the relationship between parents' and their children's mental health might work in the other direction too.

    While Howard's research hasn't evidenced a clear reason for this trend, she told The Atlantic: “If the family members interact with (交往) each other well, the kid will be more pleasant to be around and make less negative statements, which will affect how other family members think.”

    Tom Madders, director of campaigns at YoungMinds, told HuffPost UK that for parents, watching their children go through mental health problems can be difficult, especially if they feel responsible. Madders also noted that parents often make big lifestyle changes, say, giving up their jobs, to support their children with depression, particularly in cases where their children have to leave school because of their mental health problems. However, Madders thought this can only make things worse. “Parents' sacrifice adds pressure to the delicate shoulder owners,” he said.

    The process of waiting to get treatment can also be an added stressor: “Every day we get calls to our helpline from parents whose children have been waiting months for an initial assessment, or left on long waiting lists for treatment that they need … that's why it's important that the Government commits to long-term extra investment in children's mental health services.”

    Robots come in many shapes and sizes. But most have one thing in common. They are built to help people. Lately engineers have been developing new kinds of humanoid robots. These high-tech machines are designed to lend a hand everywhere from hotels to disaster areas.

    "Robots help people by making their lives easier, safer, and more fun," says engineer Omar Abdelwahed.

    Since November, a robot named pepper has been on the job at the Mandarin Oriental hotel in Las Vegas, Nevada. When guests have questions or need directions, they can ask Pepper. They can also use the robot's touch screen to find the information they need. Pepper is able to talk with guests and entertain them with stories too. It can even tell what kind of mood they are in.

    "Pepper provides our guests with information in an exciting and new way," says hotel manager Donald Bowman.

    For a kid, being in the hospital can be boring and even scary. But a small robot called NAO is helping to make hospital stays easier. It was designed to keep people company.

    A Tennessee doctor named Phil Parker bought a NAO robot three years ago. He programmed it to talk to and play with young patients. He brings it to hospitals to help sick kids. When kids get medical tests, NAO explains what is going on. The robots also reads to kids and plays games with them like rock, paper, scissors.

    "The robot gets many kids to smile for the first time since they've been in the hospital," Parker says.

    Other robots are being developed to help in places where it's hard or risky for people to go. For example, disaster areas can be full of rubble and other dangers. Engineers in Japan are building a robot called E2-DR to go into those areas and search for people who are hurt.
