A new study finds that young females in one group of African chimps(黑猩猩) use sticks as dolls more than their male peers (同龄) do, often treating pieces of wood like a mother chimp caring for a baby. In human cultures around the world, girls play with dolls and pretend that the toys are babies far more than boys do.

    Chimp observations, collected over 14 years of field work with the Kanyawara chimp community in Kibale National Park in Ugandan, provide the first evidence of a nonhuman animal in the wild that exhibits sex differences in how it plays. This finding supports an argument that biology as well as society underlies boys' and girls' different toy preferences.

    Stick play occurred most commonly between ages 3 and 9. Females spent a lot more time carrying sticks than males did. Young male chimps occasionally used sticks to mimic(模仿) childcare. "Far more often, they fought with sticks, an infrequent behavior among females," say Sonya Kahlenberg of Bates College in Lewiston, Maine, and Richard Wrangham of Harvard University.

    "Biological differences between the sexes make female chimps more receptive to stick-mothering than males," says Wrangham.

    Consistent with reported cultural traditions among adult chimps, Kanyawara youngsters learned from each other to play with sticks as if caring for babies. Stick play among young chimps showed no evidence of being directly influenced by older chimps. Child-bearing females never played with sticks and thus didn't model such behavior for younger chimps.

    Young females carried sticks for anywhere from a few minutes to several hours. They often rested in nests with their sticks, sometimes playing with them much as chimp mothers play with their babies though they didn't get any form of teaching from the adults.

    With the wide, application of the Internet, Uber, a new approach to your destination instead of taking an ordinary taxi, has become more popular recently. However, benefits won't come without its fair share of drawbacks. The ride-sharing experience is about to get awkward.

    Uber drivers are a part of the so-called sharing economy: They use their own vehicles, receive customer reviews via the app's five-star rating system and make their own hours and choices. Unlike other services, Uber claimed that drivers all over the country could dearly alert customers that tipping is not included. Those drivers that expect to be tipped can make their wishes known. But the company is holding to its official no-tip-required line. “Once you arrive at your destination, your fare is automatically charged to your credit card on file－there's no need to tip.” Although drivers value the freedom to push a button rather than punch a clock like ordinary taxi drivers, lack of a clear policy leaves Uber drivers m a vulnerable (脆弱的) and awkward position: If they ask a customer for a tip or put up a sign, that customer could give the driver a low star-rating, and the driver could finally be removed from the app.

    But has the company done a good job working with customers? Some observers say that this new grey area for tipping will create awkwardness about whether they should tip or not. Providing an option to tip on an app sends a clear message to customers to reach into their pockets. According to Guinn's 2015 survey of roughly 500 people, merely 30% people would be more likely to leave a tip if they were presented with a “no tip” button.

    If the service is twice as expensive during a rain storm or public transport delay, the customer has the right not to tip, However, if the driver is extra helpful or avoids traffic to reach your destination in a more timely manner, you could give an extra tip, says Uber, who will leave tipping options in the hands of the consumer rather than the app.

    The world's first luxury space hotel, Aurora Station, was announced Thursday at the Space 2.0 Summit in San Jose, California. Developed by US-based space technology start-up Orion Span, the space station will host six people at a time, including two crew members, for 12-day trips of space travel. It plans to welcome its first guests in 2022.

    "Our goal is to make space accessible to all," Frank Bunger, CEO and founder of Orion Span, said in a statement." Upon launch, Aurora Station goes into service immediately, bringing travelers into space quickly and at a lower price point than ever seen before."

    While a$10 million trip is outside the budget of most people's two-week vacations, Orion Span claims to offer an authentic astronaut experience. "It has taken what was historically a 24-month training to prepare travelers to visit a space station and streamlined(精简)it to three months, at a fraction(小部分)of the cost," says Bunger. During their 12-day adventure, the super-rich travelers will fly at a height of 200 miles above the Earth's surface in Low Earth Orbit, where they will witness incredible views of the blue planet. The hotel will orbit Earth every 90 minutes, which means guests will see around 16 sunrises and sunsets every 24 hours.

    Activities on board include taking part in research experiments such as growing food while in orbit, which guests can take home for a super-smug souvenir, and soaring over their hometown. Guests can have-live-video chats with their less-fortunate loved ones back home via high-speed wireless Internet access and, upon(return to Earth will be greeted with a specially arranged hero's welcome. While enjoying the thrills of zero gravity, the travelers will be able to float freely through the hotel, taking in views of the northern and southern aurora from the station's windows.   Deposits are already being accepted for future stays on the space hotel.

    The Taj Mahal(泰姬陵) is a love story, a sad and beautiful one. If it didn't exist, we would easily imagine that the story of its construction was simply a fairy tale.

    Three hundred years ago, there lived an Indian emperor called Shah Jahan. His wife was a beautiful and bright woman whom he loved greatly. Her title was Mumtaz Mahal: its shortened form Taj Mahal, means “pride of the palace”. In the year 1630 this beloved wife of the emperor died. He was so broken-hearted that he thought of giving up his throne(王位). He decided out of his love for his wife to build her the most beautiful tomb(墓穴) that had ever been seen.

    He invited the best artists and architects from India, Turkey, Persia and Arabia and finally, the design was completed. It took more than twenty thousand men working over a period of 18 years to build the Taj Mahal, one of the most beautiful buildings in the world.

    The building itself stands on a marble platform, 29 meters' square and 6-7 meters' high. Towers rise from each of the four corners. The Taj itself soars another 61 meters into the air. It is an eight-sided building made of white marble.

    The emperor planned to build an identical tomb of black marble for himself on the other side of the river connected by a silver bridge. However, his son put him into prison in the palace before he could finish, and for the rest of his life, he could only gaze across river at the tomb of his beloved wife.

    Darwin noted that some human emotional expressions might have started as part of a physiological function: for example, exposing the teeth to bite food. The function, however, took on meaning and became a form of communication which signals anger.

    The same may be true for the animals. Baby monkeys cry for attention. They also cry to signal to an adult that they want to be carried.

    “Chimpanzees do make upset voice when they are being weaned (断奶) by their mothers or have lost their mothers or another individual,” says Anne Pusey, a professor at the University of Minnesota. “They whimper (呜咽) and cry and scream. When we hear these calls, the emotion involved seems obvious. However, they do not weep in the sense of producing tears. I have seen an adolescent male whimpering when he lost sight of his older brother with whom he had been traveling.”

    Babies of many mammalian species, including rats, cry. Moreover, when a baby rat cries, often his mother brings the fallen pup back into the nest. This is probably a straightforward communication, as it is with humans. However, psychologists at the University of Iowa aren't convinced.

    The Iowan researchers can cause the same crying sounds by producing large decreases and then increases in blood flow. The blood flow also goes down when baby rats get cold. Thus, they conclude baby rats cry in the same way that we sneeze. Of course the rat baby could be crying because he's cold and wants his mother to know.

    “All young mammals make cries when separated from their mother,” says Jaak Panksepp, a psychologist at Bowling Green State University. “If you're willing to call this crying, then certainly other animals show this emotional response.” he says, “Some of us take seriously that animals do have emotions.”
