1 . Chimps use loud calls and gestures to make their feelings known but until now, the exact meaning for individual movements has remained a mystery. Now researchers believe they have translated the key gestures used in the chimp community and identified their intentions for the first time.

From 4,351 gestures, experts were able to identify 66 that are used for 19 specific message meanings, including showing a foot to tell a child they can climb on their back. The researchers were able to narrow down these 66 gestures to 36 that are used intentionally to achieve 15 purposes. The translations were made by Dr Catherine Hobaiter and her colleagues at St Andrews University in Scotland.

Dr Hobaiter used behavior sampling and filmed all recorded cases of gestural communication. Other gestures include stomping their feet to ask another chimp to stop what they are doing, and slapping objects together to ask another to follow them. Of the 19 meanings,17 encouraged interactions to start, or to develop, such as “move closer,” and “change play”. Some of the gestures were found to have more than one meaning. and only 10 of the 66 gestures were used for only a single meaning.

Researchers collected a total of 471 video clips from two social groups of chimps at a shelter near Kinshasa, Democratic Republic of Congo. As well as identifying what the gesture means, they also discovered the technique needed to increase the chances of success.

“Human children use gestures to communicate before they produce their first words, and their earliest gestures typically appear around 10 months of age,” explained the researchers. “In great apes, there is good evidence that language-trained individuals are capable of acquiring and understanding signals, but this is far less clear in their natural communication. ”

3 . In the world of Chinese archaeology (考古学), a sign of a dig's importance is the sight of Zhou Mingsheng at work. A field technician who has worked at archaeological sites all around China. Master Zhou is credited with the gentlest touch in his profession. Born into a farming family, he is a “national-level craftsman” with a talent for using simple tools to get relics (遗物) that would crumble in other hands, says his current boss, Wang Xu, director of an archaeological site at Shuanghuaishu, a Neolithic (新石器时代的) settlement near the Yellow River in the central province of Henan.

It is not beauty that attracts visitors to Shuanghuaishu. At 5, 300 years old, the settlement is the work of a culture too simple to have left behind many buried treasures. The single most precious find, to date, is a finger-length sculpture of a silkworm. Nor is the setting lovely: an area surrounded by deafening insects, between a highway and two power stations. Rather, the site's importance is historical. For since the birth of Chinese archaeology in the 1920s, it has been inseparable from claims that China has the oldest unbroken civilisation on Earth.

Leading archaeologists say that the site has the right combination of location, age and distinctive cultural elements to be the capital of an early Chinese kingdom. That would make it a bridge between China's written history and the era of the Yellow Emperor, who is said to rule over these central plains almost 5,000 years ago, though many foreign scholars doubt his existence. Chinese media call the site proof of China's 5,000 years of history.

Foreigners complain about a lack of written records, Mr Wang notes. Perhaps they are missing symbols that will one day be understood, for instance in patterned pottery. Outsiders "can't keep using Western standards to apply to Chinese ruins," he argues.

4 . Men hunted.Women gathered. But the discovery of a woman buried 9,000 years ago in the Andes Mountains with weapons and hunting tools challenges this widely accepted view. The woman, thought to be between 17 and 19 years old when she died, was buried with items that suggested she hunted big-game animals by spear (矛) throwing.

The objects accompanying people in death tend to be those that accompanied them in life. Although some scholars have suggested a role for women in ancient hunting, others have dismissed this idea even when hunting tools were uncovered in female burials.

To examine whether this woman found at this site was an exception, the researchers examined 429 skeletons at 107 burial sites from around 8,000 to 14,000 years ago. Of those, 27 individuals were buried with hunting tools—11 were female and 15 were male. The sample was sufficient to “justify the conclusion that female participation in early big-game hunting was likely nontrivial,” said lead study author Haas.

The findings add to doubts about “man-the-hunter” assumption about early humans since the mid-20th century. That theory assumes that it was men who went out and hunted, bringing home meat to feed women and children, who were responsible for gathering berries, plants and nuts to enrich the dict.

But recent research suggests hunting was very much a community-based activity, needing the participation of all able-bodied individuals to drive large animals, the study said. Meanwhile, the spears used at that time had low accuracy, encouraging participation, and using it was a skill learned from childhood. Women may also have been freed from child care demands by “allo-parenting”—raising children was a job shared by many.

“Our findings have made me rethink the most basic organizational structure of ancient hunter-gatherer groups, and human groups more generally,” Haas said.

5 . 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.

6 . A boat floated peacefully on the crystal-blue water. “How fascinating! ” Antonio told to his friends, who shared a passion for diving. In the following diving, unfortunately, he was trapped with his friend, who shared the oxygen with Antonio but died afterwards. Antonio breathed hard on his mouthpiece, but there was nothing left.He started to scream and kept screaming until he had no voice. As hours passed and Antonio failed to surface, his other friends rushed for help.

Shortly the local divers came to rescue, but in vain. Years of experience told them, lost in the cave, one must be dead. They considered going back in but decided against it because of the incoming dark, the muddy water and the lack of help. Too risky.

Asked for help, Peter, a chief frogman, began to plan the next morning’s operations, knowing hurried preparation was deadly. He had narrow escapes from death. Each time, though, training and a cool head saved him. Suddenly, a thought struck him. "Who said he died? That guy may be alive!” The next morning, Peter was suited up. Before a dive, he prayed.

Antonio "dreamed” he was drowning. He forced himself awake but couldn't feel his body. He was too tired to feel scared. Entering the cave, Peter found Antonio. On touching him, a hand closed around his left wrist Peter knew the young man must be kept from panicking. Gently he passed his mouthpiece to Antonio. He heard Antonio take a couple of breaths before handing the mouthpiece back. Antonio was trying to share oxygen with him, Peter realized. How unbelievable was that, after 17 hours in this hole, his mind still stayed cool!

Antonio was treated in the nearest hospital. Doctors said he wouldn’t have survived more than another hour in the cave. When Peter finally climbed back into his car, he doubled up, sobbing. He felt he took part in a miracle. Somehow an unseen hand that had guided Antonio to a tiny air pocket in the cave guided him there too. Where he should have found death, he had met life.

7 . When you hear the beginning of your favorite song from the radio, suddenly your neck is covered in goose bumps.

It's such a thing that a group of scientists call “skin excitement”—a feeling of cold caused not by a drop in temperature or sudden scare, but by the sense of beauty. “Skin excitement” can come from a song, a painting, a moving movie scene, or even a beloved memory-pretty much anything that causes the giving out of pleasure-soaked dopamine in your brain. But it does not come for all of us.

Your favorite music uncovers a lot about your personality，and so does how you respond to that music. Studies suppose that as few as 55 percent of people experience “skin excitement” when listening to music. And if you count yourself among this group, the goose bumps on your skin aren't the only giveaway—scientists can read it in your brain, too. In a new study published in the journal Social Cognitive and Affective Neuroscience, Harvard researchers performed brain scans on 10 students who said they reliably got cold when listening to music, and 10 students who didn't. They found that the cold-prone brains may really be excited by stronger emotions.

Cold-prone brains are generally more likely to show stronger emotional intelligence than no-cold brains. Cold-prone minds tend to have unusual active imagination, reflect more deeply on their emotions, and appreciate nature and the beauty of music and art to a stronger degree than no-cold brains.

So, what type of music causes the chills? It seems that the type is not so important; participants in the new study reported getting cold from songs of every kind. And any song connected with a strong emotional memory of the listener can produce the most reliable results. For me, that's the song Sailing to Philadelphia by Mark Knopfler, which I listened to as a kid in the car with my dad, on the way to the summer camp.

8 . I can remember when my daughter Maggie, who is now six, used to crawl into my lap and say, “Daddy, read me a story.” Last year she announced, “Daddy, I’m going to read you a story.”

Maggie was a television child. When she first became conscious of anything beyond eating and sleeping, the TV set was right there, and it soon commanded her attention.

A few years ago, we were worried not only that we’d never get the children away from the set long enough to learn to read, but that we’d forget how to read ourselves. But in 1955 there was not only more reading than before TV, but more reading than ever before in history.

Clearly, reading has survived television as it has survived a lot of other things. When I was six, a wail went up about menaces (威胁) to reading at home: motor cars and cinema. When Maggie came along, there was television. The motorcar, the radio, the cinema and television do take up a lot of time.

Well, we’ve got more time. When my mother was a girl, people worked about 60 hours a week. Now it’s 44. When Maggie grows up, it’ll be 30. And there’ll be numerous gadgets to do her housework. She’ll have to read. You can’t watch TV all day.

At present Maggie is reading about Johnny Woodchuck. Ahead of her — and I’m a little envious — are her first brush with Black Beauty, Alice stepping through the looking glass, Huck and Jim drifting down the Mississippi, the emotional storms of Shakespeare, the   spiritual agonies of Tolstoy. For reading isn’t all joy. Like life itself, it’s mixed with many moods, from ecstasy (狂喜) to despair. Maggie will learn to take the rough with the smooth, gathering from the ancient wisdom of long-dead genius a little fire to enrich her spirit.

And some day, if she’s lucky, she’ll get the biggest thrill of all, when a little girl climbs into her lap and announces, “Mummy, I’m going to read you a story.”
