Apple is to open a research lab in the southern Chinese city of Shenzhen, according to Tim Cook, its chief executive, as it seeks to boost sales in the country and improve ties with the authorities.

    Beijing has been encouraging foreign technology companies to carry out more high-end work on the mainland as part of efforts to revitalize local industry.

    It will be Apple's second facility in China. It already has a new research and development facility in Beijing.

    The two R&D centers were “aimed at strengthening relationships with local partners and universities as we work to support talent development across the country”, Apple said in a statement.

    A closer relationship with the Chinese authorities has been a priority following setbacks for the US technology company this year.

    The iPhone has been losing market share to high-end handsets made by local competitors including Huawei, Vivo and Oppo, which topped the rankings in the second quarter, while Apple languished in fifth place, according to Canalys data.

    Analysts said the announcement of the R&D centre was Mr. Cook's latest attempt to gain favour with Beijing, following the US group's $1billion investment in Didi Chuxing, the Chinese car-hailing company, in May.

    Apple has had to change its approach in China as it faces rising nationalism and high-quality local competition, according to Ge Jia, a tech blogger, who wrote yesterday: “It's time for Apple to cast aside their pride.” “Their previous strategy of only selling devices to China without leaving anything behind is not working any more and they are starting their process of localisation in China through the Shenzhen lab.”

    Climate change will force exhausted birds migrating to Europe from Africa to travel further, with possibly disastrous consequences, according to a study.

    The annual voyage of some species, which fly north in search of food and suitable habitats, could increase by as much as 400 kilometers (250 miles), the research found. “Marathon migrations for some birds are set to become even longer,” said Stephen Willis, a professor at Durham University in Britain and the main architect of the study. “This is bad news for birds like the White throat, a common farmland bird. The added distance is a considerable threat. As temperatures rise and habitats change, birds will face their biggest challenge since the Pleistocene era (更新世), which ended 11,000 years ago,” he said in a statement.

    Some 500 million birds migrate each year from Africa, some weighing as little as nine grams (three-tenths of an ounce). To complete a voyage that can be thousands of kilometers long, birds have to fatten themselves up to twice their normal weight. Some even shrink their internal organs (收缩内脏) to become more fuel efficient, so any additional distance may be dangerous.

    The study finds that from 2007 to 2010, nine out of 17 species examined are going to face longer migrations, particularly birds that cross the Sahara Desert. Some birds travel the Sahara and the Mediterranean Sea in a one go, while others have a break in northern Africa before crossing. Many fly at night, when temperatures are cooler.

    A few — such as the Blackcap — have started to adapt by spending winters in Britain, but such behavior remains exceptional, the study said. The study forecasts that the migration distance of the Orphean Warbler will jump from 2,700 kilometers (1,700 miles) to between 3,050 and 3,350 kilometers (1,900 and 2,100 miles), with even longer increases for the Subalpine and Barred Warblers.

    Youth football team members rescued more than two weeks after sudden flooding trapped them in a cave in Thailand are now being well looked after at a hospital in the northern city of Chiang Rai. In addition to treating the boys for potential body fluid loss, inadequate nutrition and lack of oxygen, their doctors also plan to closely monitor them for symptoms of diseases that may have been infected by animals living in the cave.

    "The next step is to make sure those kids and their families are safe, because living in a cave provides a different environment, which might contain animals that could transmit…disease," said the local hospital. The boys and their family members have been told to watch for symptoms such as headache, nausea(反胃), muscle pain or difficulty breathing, the reports added.

    Yet based on the location where the boys were trapped—more than four kilometers from the cave complex's main entrance, past some fully submerged passages—and the fact they have been swimming out wearing full scuba face masks, it seems unlikely that they were living with bats in the cave or breathed in bat-associated bacteria during their rescue, several infectious disease experts said. "It's hard to imagine bats got that deep into the cave because of all those narrow passageways, but it is possible," says Ian Lipkin, an animal expert and professor at the Mailman School of Public Health at Columbia University. "It's unlikely that there would be many animals in there," notes Jonathan Epstein, a doctor at EcoHealth Alliance, a nonprofit organization that studies diseases and how to prevent them. Bats typically like to rest in areas they can easily enter and exit, not in places that fully flood, he adds.

    Bats in Thailand have been linked with a wide range of viruses that are similar to severe acute respiratory syndrome (SARS)—Lipkin says. But it seems more likely the boys would have been exposed to infection-causing bacteria when they swam through the dirty water with cuts and scrapes. "If you are trying to prioritize issues with respect to health care for these kids, number one would be psychological damage and second will be bacterial infections from the cuts and scrapes they may have encountered." Lipkin says.

    More than 20 years ago, a skeleton called Little Foot turned up in a South African cave. The nearly complete skeleton was a member of the human family. Now researchers have freed most of the skeleton from its stony shell and analyzed the fossils (化石) and they say 3.67-million-years-old Little Foot belonged to a unique species.

    Researcher Ronald Clarke and his colleagues think Little Foot belonged to A. Prometheus (普罗米修斯南猿). Clarke works at the university of the Witwatersrand in Johannesburg South Africa. He studies fossilized humans and our relatives. Their foundings, published in four papers, have suggested the species A.Prometheus might have existed. Clarke has believed in that species for more than a decade, he found the first Little Foot's remains in a storage box of fossils in 1994. People began digging out the rest of the skeleton in 1997.

    Many other researchers instead argue that Little Foot likely belonged to a different species, which is known as A.africanus (南方古猿非洲种). Researcher Raymond Dart first identified A.africanus in 1924. He was studying the skull (头颅骨) of an ancient youngster called the Taung Child. Since then, people have turned up hundreds more A. africanus fossils in South African caves. Those include Sterkfontein, where Little Foot was found.

    The braincase is the part of the skull that holds the brain. And researchers found a partial braincase that Dart thought belonged to a different species in Makapansgat, one of those other caves. In 1948, Dart called this other species A. Prometheus, but he changed his mind after 1955. Instead, he said that braincase and another fossil at Makapansgat belonged to A.africanus. There was no A. Prometheus after all, he concluded.

    Clarke and his colleagues want to bring back the rejected species. They say Little Foot's distinctive skeleton, an adult female that is at least 90 percent complete, is solid evidence for it.

Sometimes the toughest thing about feelings is sharing them with others. Sharing your feelings helps you whether your feelings are wonderful or terrible. Sharing also helps you to get closer to people you care about and who care about you. But how?

 You can't tell your friends what's inside our backpack if you don't know what's in there yourself. {#blank#}1{#/blank#} Before you can share them with anyone, you have to figure out what feelings you have. {#blank#}2{#/blank#} You can do this in your mind or by writing them out or even by drawing pictures. Is something bothering you? Does it make you frustrated or terrified? Do you feel this emotion only once in a while or most of the time?

 The way a person feels inside is important. If you keep feelings locked inside, it can even make you feel sick! {#blank#}3{#/blank#} It doesn't mean your problems and woes magically disappear, but at least someone else knows what's bothering you and can help you find solutions.

 Your mom and dad want to know if you have problems and what's happening in your life. But what if a kid doesn't want to talk with parents? Then find another adult you trust like a relative or a teacher at school. {#blank#}4{#/blank#}

 Once you know who you can talk with, you'll want to pick a time and place to talk. You can talk publicly in your family. But some kids are more private than others and they will feel shy about sharing their feelings. {#blank#}5{#/blank#} A kid doesn't have to share every feeling he or she has.

Spreading kindness not only helps others feel better about themselves but also boosts the giver's health and happiness, according to a study. {#blank#}1{#/blank#}

Giving seems to lower our blood pressure.

{#blank#}2{#/blank#}. One study asked a group of hypertensive (高血压的) people to spend $40 on themselves, while another group of people with high blood pressure were told to spend the money on others. They found that spending money on others had reduced their blood pressure at the end of the six-week study

A recent study found that people who said they would donate money to help orphans were less sensitive to an electric shock than those who declined to give. According to the study, regions of the brain that react to painful stimulation appear to be instantly out of operation by the experience of giving.

Being kind seems to boost happiness.

Another study assigned people to three groups: the first group had to do an act of kindness each day; the second group tried a new activity each day; and the third group did nothing. The first two groups saw a significant boost in happiness. {#blank#}4{#/blank#}, if you're creative with your acts of kindness, than those who performed the same activity over and over again.
