When your boss calls and tells you to send $100,000 to a supplier, be on your toes. It could be a fake call. As if fake emails weren't enough, on the rise now is the deep fake audio (虚假音频) that can be cloned to sound almost real and perfect and is easy to create. "It's on the rise, and something to watch out for," says Vijay Balasubramaniyan, the CEO of a company called Pindrop.

Balasubramaniyan stated during a safety meeting how easy it is to use machine to create sentences that a person probably never said from recorded words. "All you need is five minutes of audio, and you can create fake audio," says Balasubramaniyan. Then, he showed a database (数据库) of voices, typed a sentence, and connected it to a famous people's name on the list. A few seconds later, he clicked "play", and it sounded quite real.

More costly are fake phone calls, where cheaters are able to fake the phone number of real contacts and make calls that result in workers sending off lots of money. He mentioned the example of a United Kingdom energy company in 2019 that got attacked by deep fake audio in a call that asked a worker to send $243,000 to a supplier. Reported by the Wall Street Journal, the worker was directed to pay it within an hour.

Balasubramaniyan says if you were to get that kind of call from a "boss" be doubtful and ask to call back right away to prove authenticity (真实性). Besides this, in his opinion, companies need to use more safety measures for keeping up with deep fake artificial intelligence (AI) that produces phone calls and software to check authenticity versus fake calls. "This is a threat that's waiting to happen," he says. "It's a very small number now, but it's very real."

    Changing the Guard

    For a display of British ceremony, watch Changing the Guard outside Buckingham Palace. This is where one member of Queen's Guards exchanges duty with the old guard. Both guards are dressed in traditional red uniform and bearskin hats, and the handover is accompanied by a Guards band. Guard Mounting takes place at 11:30 am. It is held daily from May to July, and on alternate(间隔的)dates throughout the rest of the year.

    Sir John Soane's Museum

    Sir John Soane was an architect. During his lifetime he collected some valuable antiquities(古董) from all four corners of the globe. They are now on display in Sir John Soane's Museum which gives a real insight into the life of this outstanding Victorian gentleman.

    Geffrye Museum

    A very unique experience, the Geffrye Museum, located in 18th century almshouses(救济院),gives a fascinating insight into the lives of the British middle classes from the 1600s to the present day. Explore a series of room sets, complete with furnishing and textiles(纺织品)from each period.

    Hogarth's House

    Hogarth was very famous and criticized 18th century society in his engravings(雕刻),such as A Harlot's Progress, A Rake's Progress and Marriage a-la-Mode. As the name suggests, Hogarth's House is where he lived before he died in 1764, and it's here that you'll find the most extensive collection of his paintings on public display.

    China has announced it's abolishing its one-child policy. What difference has it made, statistically speaking?

    400 million births prevented. The one-child policy, officially in place since 1979, has prevented 400 million births. Parents have faced fines and other punishments for having more children.

    The majority of the decrease in China's fertility(生育)rate happened in the 1970s.It dropped from 5.8 children per woman in 1970 to 2.7 in 1978. Despite the one-child policy the rate had only fallen to 1.7 by 2013. 21:28 baby death rate. Since the one-child policy was introduced, baby girls have become more likely to die than boys.

    In the 1970s, according to the United Nations, 60 males per 1,000 live births died under the age of one. For girls the figure was 53. In the 1980s, after the one-child policy became official, the rate for both was 36. By the 1990s, 26 males per 1,000 live births died before the age of one-and 33 girls. The 2000s saw 21 boys per 1,000 live births dying and 28 girls.

    1.16 boys born for every girl

    Sexually selective abortions have been considered as a major cause of China's unusual sexual imbalance.

    Gietel-Basten, associate professor in social policy at Oxford University, says the births of many girls are not registered if parents have broken the rule by having two children, adding officials often turn a blind eye. It's estimated there are now 33 million more men than women in China.

    4:2:1 families

    With the ageing of China's population and the continuation of the one-child policy, a “4: 2 :1”home is the description given to households in which there are four grandparents cared for by two working age parents, who themselves have one child.

    By 2050, it's predicted that a quarter of China's population will be 65 or older. The predicted decline in the number of people of working age is thought to have persuaded the government to drop the one-child policy.

    On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk, Strayer explained that all this time spent with technology is making our brains tired.

    Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains, is important for critical thinking, problem­solving and decision­making.

    So, it is important to give the brain a rest. And being in nature, Strayer claims, helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore, swim, sleep, eat and play. Camping may be just what a tired brain needs.

    Take Carl for example. He lives in West Virginia and enjoys camping. He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children. She calls it a "regenerative" experience.

    At the University of Utah, David Strayer has studied both short­term and long­term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However ,he found, it is the long­term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

    The summer I turned 16, my father gave me his car — a gift wasted on me at that age. The important thing was that Hannah and I could drive around.

    Hannah was my best friend, a year younger but much taller, almost five foot ten. "Hannah's a knockout, "my mother always said. And that summer she signed with a modeling agency. She was already doing runway work.

    A month after my birthday, Hannah and I went to the movies. On the way home, we stopped at the McDonald's drive-through, putting the fries on the seat between us to share. "Let's ride around a while, "I said. It was a clear night, full moon slung(悬挂)low over the desert. Taking a turning too fast, I plowed (撞)through a neighbor's wall and drove into a full-grown tree.

    We were taken in separate ambulances. I'd cracked(使裂开)my cheek bone; Hannah's forehead had split wide open. End of her modeling career. What would I say to her?

    When her mother, Sharon, came into my hospital room, I started to cry. She sat beside me and took my hand. "I rear-ended(追尾) my best friend when I was your age, "she said. "I totaled her car and mine."

    "I'm so sorry," I said.

    "You're both alive," she said." The rest is window dressing. I forgive you. Hannah will too."

    Sharon's forgiveness allowed Hannah and me to stay friends throughout high school and college, to be at each other's weddings … The scars are so faded no one else would notice, but in the sunlight I can still see it just below her hairline — for me, a mark of grace(优雅).
