Thousands of persons in Peru are suffering from the disease cholera. Medical experts say it is the first time in their century that cholera has reached the western part of the world. The Untied States Centers for disease Control says the kind of cholera has been spreading throughout the world since 1961. It was discovered that year in Indonesia. Since the first case in Peru, more than sixteen thousand people have been affected and about one hundred have died.

    Cholera is caused by polluted food and water. People become infected (传染 ) when they eat the polluted food or drink the polluted water. If untreated immediately, they may die within hours. Most victims however , can be saved. treatment includes drugs and replacement of body fluids ( 液体) directly into the blood.

    Medical researchers have developed a vaccine ( 菌苗) medicines to protect against cholera. But the vaccine is only about 50% effective. And it protects against cholera for only about six months. Medical experts say the best way to fight cholera is to prevent it. They also say people should not eat uncooked food or food that has not been cooked long enough. People who live in areas where cholera has been found should wash their hands before eating and cooking. They should drink only water that has been boiled or made pure with chemicals.

    According to a new US study, couples who expect their children to help care for them in old age should hope they have daughters because they are likely to be twice as attentive overall.

    The research by Angelina Grigoryeva, a sociologist at Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members.Her analysis of the family networks of 26,000 older Americans concluded that gender(性别) is the most important predictor(预示物) of whether or not people will actively care for elderly parents.

    In a paper being presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men statistically likely provide less care.

    Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a cross-section of over-50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.

    “Whereas the amount of elderly parent care daughters provide is associated with limitations they face, such as employment or childcare, sons' caregiving is associated only with the presence or absence of other helpers, such as sisters or a parent's spouse(配偶),” she explained.

    “Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.”

    “This suggests that sons pass on parent caregiving responsibilities to their sisters.”

    In the UK, the 2011 census(人口普查) showed that there are now around 6.5 million people with caring responsibilities – a figure which has risen by a tenth in a decade.

    But many are doing so at the risk of their own health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a full- time job are three times more likely to be struggling with ill health than their working counterparts(相对应的人) who are not carers.

    A company in San Francisco, California, has found a way to turn used plastic bottles into women's shoes.

    Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.

    A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Roth Martin is the company's co-founder. He explains how they turn plastic into soft material for women's feet. They take the plastic, clean it, and break it down into small pieces. Then they press them through a device that makes soft fibers. Those fibers are then combined together. This is done by a 3D machine. It is designed to reduce waste while making the shoes. The knitted stuff and the inner part of the shoe are then attached to the shoe's outer part, called the sole. This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.

    Rothy's shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $ 125 or $ 145 per pair, depending on the design. After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew. Martin says there is no shortage of material to fill that demand. "We're not going to run out of water bottles any time soon. So we have a limitless supply of material, and I think that is a good sign for our future." When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled material to make other products.

    For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.

    I can proudly say that last year I broke the record for the oldest person in the world to ride a roller-coaster. I'm 105, but I feel younger. Even the doctor agrees I'm in good condition. I'm a bit deaf and my legs feel weak, but they are the only issue.

    I rode the Twistosaurus at Flamingo Land, which spins you round quite fast. I didn't choose to go on that. I'd have preferred a really fast one that went upside down. But I was told I couldn't ride something like that, because my blood pressure could drop and I might have some danger.

    I wasn't nervous — I don't get frightened of anything. I was securely fastened, so I knew I wouldn't fall out. The roller-coaster ride went on for three or four minutes, and it couldn't be a better experience. And I raised a lot of money for the Derbyshire, Leicestershire & Rutland Air Ambulance fund, which was fantastic.

    People were saying I'd got a place in the Guinness World Records. Later, someone came to present me with the certificate. I had it on the wall in my living room, with another one that got a year earlier.

    My record-breaking ways really began a couple of years ago, with the ice-bucket challenge. It turned out that I was probably the oldest person in the world to do it, and the video was very popular. After that, I stared to think about what else I could do to raise money for different charities.

    I'm not sure if anyone admires all the fun I'm having. They just say I'm daft and that's about it. But I've had many good days and many exciting times. I've had a really good life. I don't think I've wasted any of it.

Donna Strickland was awarded the 2018 Nobel Prize in Physics jointly with Arthur Ashkin and Gérard Mourou.It's the first time in 55 years that a woman has won this famous prize, but why has it taken so long? We look at five other pioneering female physicists — past and present — who actually deserve the prize.

Jocelyn Bell Burnell

Perhaps the most famous snub (冷落): the student Bell discovered the first radio pulsars in 1967, when she was a PhD student at Cambridge.The Nobel Prize that recognised this landmark discovery in 1974, however, went to her male supervisor, Antony Hewish.Recently awarded a £2.3 million Breakthrough Prize, which she gave away to help under-represented students, she joked to The Guardian, "I feel I've done very well out of not getting a Nobel Prize."

Lene Hau

Hau is best-known for leading the research team at Harvard University in 1999 that managed to slow a beam of light, before managing to stop it completely in 2001.Often topping Nobel Prize prediction lists, could 2019 be Hau's year.

Vera Rubin

Rubin discovered dark matter in the 1980s, opening up a new field of astronomy.She died in 2016, without recognition from the committee.

Chien-Shiung Wu

Wu's "Wu experiment" helped disprove the "law of conservation of parity".Her experimental work was helpful but never honoured, and instead, her male colleagues won the 1957 Nobel Prize for their theoretical work behind the study.

Lise Meitner

Meitner led groundbreaking work on the discovery of nuclear fission.However, the discovery was acknowledged by the 1944 Nobel Prize in Chemistry, which was won by her male co-lead, Otto Hahn.
