Telepathy (心灵感应) is the ability to communicate without the use of the five senses. It's an instinct (本能) which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct, we're using resources within the unconscious mind. When the resources of two persons' unconscious minds link together into the same frequency (频率), we call it telepathy.

    We can either send or receive telepathy. If you know who is calling before you answer the ringing phone，you are probably a good receiver. If you think of a person and he/she calls you，you are most likely to be better at sending.

    You can easily put your ability to the test. Thinking of somebody and wish him or her to contact you. Be patient. The other person may not be a good receiver，but they should contact you much earlier than would normally be expected. Or whenever the phone rings，try ‘feeling' who is contacting you. Don't guess, but try to feel it with your mind. However，if neither of these works for you，that doesn't mean that you have no ability of telepathy. As mentioned earlier, telepathy is most likely to turn up in case of emergency.

    Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams have a clear connection. These people are probably linking to each other's unconscious mind.

    Telepathy & relationship. The more people spend time together, the more likely they are to be able to link up to the other's mind, especially when separated. There are two reasons for this. One is that they understand the other's mind through time spent together; the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child's eagerly wanting his or her mother, knowing that this is the person who would always want to be there for them, and the mother's deep desire to protect her child from harm.

    When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie,“ Homeless to Harvard: The Liz Murray Story”, shown in late April.

    Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.

    Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “What drove me to live on had something to do with understanding, by understanding that there was a whole other way o f being. I had only experienced a small part of the society,” she wrote in her book Breaking Night.

    She admitted that she used envy to drive herself on. She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”. She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS.“I love my parents so much. They are drug addicts. But I never forget that they love me all the time.”

    Liz wants moviegoers (who often see films) to come away with the idea that changing your life is “as simple as making a decision”.

    Ever get that feeling you're being watched? Well, if you're a dog-owner, you may have a point. Dogs are able to watch people's interactions with one another to determine who holds yummier treats, according to a new study. This study joins others that show dogs are good observers of human behaviors and feelings. It offers evidence that dogs use information not only from people's direct interactions with them, but also their interactions with one another.

    In the study, dogs watched a man ask two women for some of their corns. Both women gave the man corns when he asked, but in response to one woman, the man showed his enthusiasm and said the corns were so delicious. In response to the other woman, he gave the corns back and called them gross（in Spanish；the study was conducted in Argentina）. After these interactions, the man left and an assistant holding the dog let the dog go. While many dogs didn't approach either woman, the dogs that did have a preference tended to prefer the woman with the yummier(美味的) food.

    Other studies of dogs' people-watching ability have found dogs are able to tell the difference between happy and sad faces in their owners. They prefer people who give others food when asked over people who don't give others food. And in one study, dogs turned toward crying people more often than toward talking people.

    So how much do dogs really understand about the humans around them? That's not totally settled yet. In a strange twist to the Argentine study above, when the researchers tried an experiment in which they put two plates of corns on a table and had a man react to each plate, dogs didn't preferentially approach the tastier plate afterward. You could say dogs watch for the interaction between two persons, not just how a person reacts. Yet a previous study found dogs will choose boxes that people reacted to happily, but not boxes people reacted to with a disgusted face.

    Well, either way, you can be sure Fluffs is keeping an eye on you, to the best of her ability. The study was published in the journal PLOS One.

    It used to be a matter of fact when Peter Pan-a character from James Matthew Harrie's 1911 book-said: “All children, except one, grow up.”

    But this “fact” doesn't seem to apply to today's world anymore.

    According to the NPD Group, a US market research company, sales of toys to adults in the UK increased by more than 20 percent in 2016, three times the pace of the children's toy market itself. These toys varied from puzzles and Lego building sets to vehicle models and action figures. And more than half of the sales came from millennials-people born between the 1980s and 2000s.

    “Adults of the 21st century are channeling their inner child, one toy at a time,” commented website Koreaboo. This is also why these adults are sometimes looked to as “kidults”.

    According to Frederique Tutt, an analyst at NPD, the motivation of these grown-ups is to escape the stress of today's fast-paced world. They are driven toward the more immediate pleasures brought by toys than those brought by, say, getting a promotion, which is far less easy to achieve.

    “It reminds me of the playful side of life,” Rob Willner, a 25-year-old PhD student in the UK, told The Telegraph when talking about his love for Lego, which he said brings him both comfort and pleasure.

    Despite this, some social scientists see the trend as disturbing. To Frank Furendi, a professor at the University of Kent in the UK, the fact that so many adults are seeking “the excitement of youth” is the evidence that “adulthood has got nothing attractive about it anymore”, he told The New York Times. “That's actually quite sad.”

    But scientists are probably just worrying too much. According to Canadian comic book artist Todd McFarlane, collecting toys could simply be a way for people to express their individuality. “It's just pop culture stuff. It's stuff that says, ‘I like a little of this and I like a little of that',” he told ABC News. “It's no big deal.”

    So now that over 100 years have passed since Peter Pan, perhaps it's time to introduce a new “fact”, as stated in the tagline(标语) of the UK fashion brand KIDULT: “Growing old is mandatory (被迫的), but growing up is optional.”

    During my third year of university, I spent six months studying in Rio de Janeiro, Brazil. Many are worried about travelling to Rio but I promise, it is worth a visit. Now I want to share my top recommendations (推荐) for experiencing Rio less as a tourist but more like a native Brazilian.

    Pedra Bonita

    Rio is full of hiking routes, and some Brazilians love to spend an afternoon hiking. My favorite route of all has to be Pedra Bonita. Pedra Bonita involves a steep climb of about an hour through tall trees, and I admit it is difficult in Rio's heat, but you are rewarded at the top with a wonderful view of the city, standing high above the green landscape and blue sea below.

    Mureta da Urca

    One thing you are sure to find in Rio is an amazing sunset, but a lot of the best spots tend to be full of tourists. In my opinion, Mureta da Urca is the most relaxing place to watch the sun set over the silver sea, with the figure of Christ the Redeemer standing tall in the background.

    Pedra do Sal

    Pedra do Sal is a historical area in the city centre and on Monday nights it is brought to life by the sound of samba. Hundreds of people gather in the street, food and drink stalls are set up and it becomes a giant street party with everyone enjoying the happy sound of live samba!

    Picanha

    If there were one Brazilian food I could bring back to the UK, it would be picanha. It is the tastiest cut of steak I have ever tasted, served alongside rice and beans.

Every four or five years, vast quantities of warm water build up along the west coast of South America. This phenomenon, El Nino, creates storms that cause destructive floods. The result is costly.

Modern farmers come to terms with El Nino. They use money saved in good years to rebuild in bad ones. But history suggests it need not be like that. In a paper published recently, Ari Caramanica, an archaeologist at University of the Pacific, in Lima, shows how it used to be done. And the answer seems to be, "better".

Dr Caramanica and her colleagues have been studying the Pampa de Mocan, a coastal desert plain in northern Peru. Pampa de Mocan is not suitable for farming. Its soil contains little organic matter and the annual rainfall in non-Nino years is usually less than two centimeters. Today's farmers therefore depend on canals to carry water from local rivers to their fields.

It had been assumed that ancient farmers had a similar arrangement — and so they did. But Dr Caramanica also found eight canals that could carry water far beyond the range of modern farms. She thinks that they were intended to guide the floodwaters arriving during Nino years. Around a quarter of the ancient agricultural infrastructure of this area seems to have been built only for managing Nino-generated floodwaters.

Evidence from pollen supports this theory, revealing that Pampa de Mocan produced lots of crops in some years, while remaining nearly barren in others. The team also uncovered two cisterns in the area serviced by the extended canals. These, probably, were used to store extra flood-water.

These findings suggest that, rather than resisting El Nino, early farmers in Pampa de Mocan were ready to make use of it when it arrived. Modern farmers might do well to learn from them.
