2 . There’s just a 1 in 3, 700, 000 chance that a person will be killed by a shark in their lifetime, but the fear is still enough to have swimmers worrying about being perceived as prey (猎物). Now, new research supports the long-standing theory that when great whites do go in for a bite, it’s a case of “mistaken identity”.
A team of biologists from the UK and Australia compared videos of seals swimming with videos of humans swimming. They then edited the videos to simulate (模拟) a great white’s vision — the sharks are likely colorblind, and they can’t make out fine detail-and found that from the point of view of the ocean creatures, humans do indeed bear a strong resemblance to seals.
“Great white sharks are often regarded as ‘mindless killers’ and ‘fond of human flesh’. However, that's not the case — we just look like their food,” Laura Ryan, lead author of the study, said.
Despite their dissatisfying vision and spatial perception, great white sharks are highly visual creatures, and rely on motion and shadows when on the lookout for prey. To really see through the species’s eyes, the research team had to get creative.
“We attached a camera to an underwater scooter (轻便小车), and set it to travel at a typical speed for predatory sharks,” Ryan said in a statement. The researchers then paired the recordings with computer models to simulate how similar people look from a shark's view below the surface.
“I knew there would be some similarities, but not to the extent we have found,” Ryan said. “Specifically, I thought swimmers might not be as similar as surfers to seals as they typically aren’t involved in as many shark bites. However, the swimmers are also difficult to tell apart from seals.”
Ryan put it in a statement, “Understanding why shark bites occur can help us find ways to prevent them, while keeping both humans and sharks safer.”

A New Addition to the Family
For the initial ten years of his life, Victor was the prince of the household. As he was an only child, his parents petted him and showered all their love and attention on him. Whatever toys his parents bought, they were always meant for him. Whatever food was in the refrigerator, there was no one to compete with him to polish it off first. Victor could leave his toys or books around the house with complete ease of mind, knowing that there was no one who would get their hands on his belongings and cause any damage.
However, all that was to change overnight when Victor’s parents brought back his new baby sister, Lina, from the hospital. With her rosy cheeks, wide open eyes and angelic smile, Lina caught the hearts of her parents, grandparents and relatives. Everyone focused their attention on the cute bunch of joy. Whenever she cried, her mother or father would rush to her bed. She simply cried because she wanted to be carried. There was little time left for Victor.
Now that Victor’s mother had his baby sister to take care of, she expected Victor himself to do most of the chores he can do. Victor was asked to clean his own room, iron his own school uniform and clean his own shoes. Before Lina’s arrival, he had never lifted a finger to help out with these tasks. The whole family also went out less because it was unhealthy to expose Lina to the bacteria(细菌) being in the outside world too often.
Victor felt neglected by his parents. He felt that they loved Lina more than him. As a result, he tried to attract his parents’ attention by becoming resistant. One evening, Victor’s parents were called up by his teacher because Victor had got into a fight at school. His teacher had noticed Victor’s behaviour and work attitude changing downwards in the past two months. Before that, he had been a model student.

Scientists at the Massachusetts Institute of Technology (麻省理工学院) have turned spider webs into music——creating an strange soundtrack that could help them better understand how the spiders output their complex creations and even how they communicate.
The MIT team worked with Berlin-based artist Tomas Saraceno to take 2D (two- dimensional) laser (激光) scans of a spider web, which were linked together and made into a mathematical model that could recreate the web in 3D in VR (virtual reality). They also worked with MIT’s music department to create the virtual instrument.
“Even though the web looks really random (随机),there actually are a lot of inside structures and you can visualize (可视化) them and you can look at them, but it’s really hard to grasp for the human imagination or human brain to understand all these structural details,” said MIT engineering professor Markus Buehler, who presented the work on Monday at a virtual meeting of the American Chemical Society.
Listening to the music while moving through the VR spider web lets you see and hear these structural changes and gives a better idea of how spiders see the world, he told CNN. “Spiders use vibrations (振动) as a way to locate themselves, to communicate with other spiders and so the idea of thinking really like a spider would experience the world was something that was very important to us as spider material scientists,” Buehler said.
Spiders are able to build their webs without shelves or supports, so having a better idea of how they work could lead to the development of advanced new 3D printing techniques. “The reason why I did that is I wanted to be able to get information really from the spider world, which is very weird and mysterious,” Buehler explained. In addition to the scientific value, Buehler said the webs are musically interesting and that you can hear the sounds the spider creates during construction. “It’s unusual and eerie and scary, but finally beautiful.” he described.

6 . If you’re an un-decider, even the simplest decisions can make your pulse race.
Go for good enough
Since perfectionism and indecision often go hand in hand, you should be moving from a mind-set that “only the best will do” to “good enough is good enough”. It helps to reflect on your original goal. Did you begin the exhausting online shopping to find a toaster that could clean itself, roast carrots and also charge your cellphone? Or were you just looking for something that would brown your bread?
Outsource ( 外包) decisions
Research has shown that choices weaken the willpower and lead to decision fatigue (疲劳). That’s why indecisive people are advised to pick their “battles”.
The 90 percent Rule
When a yes-or-no decision has many pros and cons, try the “90 percent rule”. This involves evaluating an opportunity on a scale from 0 to 100. If your interest falls anywhere below 90 percent, reduce its score to zero and reject it.
If you’re deciding whether to move across the country, imagine you’ve asked your best friend to choose for you. On the big day, she hands you an envelope; inside, it announces you’re leaving next month. Do you feel excited? Or disappointed? Using thought experiments to separate important variables can help you cut through the fog to see clarity.
A.Cut through the fog |
B.Turn to friends for help |
C.You could rely on habits and routines |
D.In other words, be choosy about choosing |
E.Remembering your purpose can simplify the process |
F.Think about how you’d feel if you scored a 65 on some test |
G.And big, life-changing choices can cause a state of breaking down |
