Working with a group of baboons (狒狒）in the Namibian desert, Dr. Alecia Carter of the Department of Zoology，Cambridge University set baboons learning tasks involving a novel food and a familiar food hidden in a box. Some baboons were given the chance to watch another baboon who already knew how to solve the task, while others had to learn for themselves. To work out how brave or anxious the baboons were, Dr. Carter presented them either with a novel food or a threat in the form of a model of a poisonous snake.

    She found that personality had a major impact on learning. The braver baboons learnt, but the shy ones did not learn the task although they watched the baboon perform the task of finding the novel food just as long as the brave ones did. In effect, despite being made aware of what to do, they were still too shy to do what the experienced baboon did.

    The same held true for anxious baboons compared with calm ones. The anxious individuals learnt the task by observing others while those who were relaxed did not, even though they spent more time watching.

    This mismatch between collecting social information and using it shows that personality plays a key role in social learning in animals, something that has previously been ignored in studies on how animals learn to do things. The findings are significant because they suggest that animals may perform poorly in cognitive (认 知的）tasks not because they aren't clever enough to solve them，but because they are too shy or nervous to use the social information.

The findings may impact how we understand the formation of culture in societies through social learning. If some individuals are unable to get information from others because they don't associate with the knowledgeable individuals，or they are too shy to use the information once they have it，information may not travel between all group members, preventing the formation of a culture based on social learning.

    People and animals often enjoy loving relationships with each other. When people adopt domesticated (家养的) animals into their families as pets, animals give humans the blessings of companionship and fun in return. In the wild, animals sometimes carry out dramatic rescues of people in dangerous situations, miraculously (奇迹般地) sensing human needs and jumping in without fear to help.

    In 2000, a 6-year-old boy unified Elian Gonzalez left Cuba on a boat bound for Florida in the United States, but the boat sank and everyone aboard drowned except Elian and two adults. Elian and the other two survivors held onto inner tube for 48 hours to try to stay afloat in the sea. After a while, however, Elian began to lose strength, slipping under the water and then grabbing the tube again as he fought to stay alive.

    A small group of dolphins noticed Elian struggling and swan over to him to help. The dolphins formed a circle around the inner tube and took turns using their noses to lift Elian until fishermen working in the area discovered and rescued Elian and the two adults who floated nearby. The fishermen reported that, when they discovered Elian, he was repeating a prayer that his mother had taught him before drowning, asking guardian angels to protect him.

    Miraculously, the dolphins knew that a child would need more help than adults, so they focused on Elian — and they figured out exactly what needed to be done and cooperated to carry out that plan successfully. They made it!

    Do you like eating processed meat? If you do, think twice now if you want to eat such meat for the sake of your health. Why? It's because eating processed meat can cause cancer, World Health Organization (WHO) experts said last Monday.

    Processed meat is the meat that has been preserved by salting, smoking, drying or canning. Experts from the WHO's International Agency for Research on Cancer (IARC) in Lyon, France studied 800 patients. The experts connected processed meat, such as hot dogs and bacon, with at least three kinds of cancer. A person who eats 50 grams of processed meat per day—about two pieces of bacon—increases his or her risk of bowel(肠) cancer by 18 percent.

    The IARC has included processed meat in its Group 1 list, for which there is “enough evidence” of connection with cancer. Tobacco is also on the Group 1 list.

WHO experts also say red meat, including beef, lamb and pork, is “probably” carcinogenic (致癌的) to humans. Dr. Kurt Strait is with the IARC. He said in a statement that the risk of cancer increases with the amount of meat a person eats. Health experts in some countries advised against eating large amounts of red and processed meat. But those suggestions had been centered on the increased risk of heart disease and obesity.

    However, meat industry groups protest the result of the WHO study. They say that meat is part of a balanced diet. They also say the causes of cancer are broad, and include environment and lifestyle factors.

    The WHO report cites the Global Burden of Disease project, which shows that diets high in processed meat lead to 34,000 cancer deaths per year worldwide.

    An elderly carpenter was ready to retire. He told his employer of his plans to leave the house building business and enjoy his late life.

    The employer was sorry to see his good worker go and asked if he could build just one more house as a personal favor. The carpenter said yes, but in time it was easy to see that his heart was not in his work. He did his job carelessly and used inferior materials. It was an unfortunate way to end his career.

    When the carpenter finished his work, the employer came to examine the house and handed the front-door key to the carpenter. "This is your house," he said, "my gift to you."

    What a shock! What a shame! If he had only known he was building his own house, he would have done it all so differently. Now he had to live in the home he had built none too well.

    So it is with us. We build our lives in a distracted way, reacting rather than acting, willing to put up less than the best. At important points we do not give the job our best effort. Then with a shock we look at the situation we have created and find that we are now living in the house we have built. If we had realized, we would have done it differently.

    Think of yourself as the carpenter. Think about your house. Each day you hammer a nail, place a board, or build a wall. Build wisely. It is the only life you will ever build. Even if you live it for only one day more, that day deserves to be lived well. The plaque (匾牌) on the wall says, "Life is a do-it-yourself project."

    Who could say it more clearly? Your life today is the result of your attitudes and choices in the past. Your life tomorrow will be the result of your attitudes and the choices you make today.

A Japanese start-up called Ashirase is stepping into the global market with a new navigation (导航) assistance product intended to help people with low vision.

Its new product will feature flexible vibrating (震动) bases around each foot and are put into each shoe, and a small pack that can be removed for charging (充电). Once fitted, the vibrating parts are set along the sensitive nerves on the foot and can send coded walking instructions to the user.

Its present form navigates a route that comes from a smartphone app. It can help clear up distractions by freeing up the attention that is normally needed to either listen to voice directions or check the phone. Visual-damaged users can use their hearing to listen to traffic sounds and signals, like warning beeps at crossings or sidewalks, and use their hands to carry walking sticks or other belongings.

The device is paired with an app through a Bluetooth connection. The app uses information from Google Maps or similar vendors to draw up a walking route to the destination. Based on the destination and how the user is walking, it will send signals to the device that will cause a vibration on the foot.

The device will vibrate at a regular frequency at the front of the foot to let the users know they're on the right track and should keep going straight. It will speed up the vibrations once the user is approaching a turn and needs to stop, and it will vibrate in either the left or right shoe to signal the direction the user needs to turn.

Ashirase's new tech is waterproof and washable. It can be charged at the end of the week to power through seven days of walking, accounting for three active hours each day. And it can be fitted in two types of shoes: sneakers and leather lace-up shoes.

Waking up in the morning, you find that you forget to set your wake-up alarm and soon you realize you're going to be late for school or work, causing a panic. {#blank#}1{#/blank#}. So you often leave home stressed, hungry, and thirsty. If this stressful morning routine is common for you, here are some suggestions to help improve it. 

Wake up on time. It's important to wake up on time(or even earlier)to set a positive tone for the day. {#blank#}2{#/blank#}. And you can avoid the last-minute rush and have a more relaxed start to your day, allowing you to face challenges with a clearer head and a more positive attitude. 

Make your bed. This seemingly insignificant act can have a deep effect on your motivation and productivity throughout the day. Research suggests that people who make their beds first thing in the morning are more likely to experience a sense of accomplishment, which can contribute to greater motivation and higher levels of productivity as they handle the tasks and challenges ahead. {#blank#}3{#/blank#}.

Take a 10-minute morning walk. Walking outdoors in the morning can be an incredibly rewarding experience, especially if you have a dog who enjoys accompanying you. {#blank#}4{#/blank#}. The fresh air that greets you as you step outside has the power to refresh your mind, helping you to get rid of sleepiness. 

{#blank#}5{#/blank#}. Organized people tend to do this regularly. It helps them stay on top of their tasks at home, work, and beyond. Make use of the morning time to review your to-do list, mark off completed items, and prioritize(优先处理)your remaining tasks. This can give you a sense of control and direction for the day. 

A. Check your to-do list. 

B. Write down things you're grateful for. 

C. There's no time for any food or drink. 

D. It will give you space and time to complete your morning routine

E. You'll be rewarded by a tidy room, and a feeling of self-satisfaction. 

F. Each morning is the start of a new day, so why not learn something new? 

G. But even if you don't, why not try taking a brief walk outdoors each morning?
