    CITIES DRIVE ANIMALS AND PLANTS TO EVOLVE
    Species are adapting to urban pollution, traffic and shrinking habitats through changes in their genes By Sharon Oosthoek - Apr 6, 2017

    Imagem da questão de Inglês, Universidade Federal dos Vales do Jequitinhonha e Mucuri de Minas Gerais 2017, Interpretação de texto | Reading comprehension

        Ever seen a raccoon open a trash can in search of leftovers? Or walk across power lines to get from one rooftop to another? If so, you've witnessed an animal adapting its behavior to city life. That's been going on since people started building cities thousands of years ago. Now, biologists are seeing signs that animals and plants are also adapting in a more basic way to survive in cities. Their genes are changing.
         Genes are segments of DNA that influence how an organism looks and functions. An animal or plant’s DNA is like an instruction book for how it develops and grows. Some instructions guide its reproductive habits. Others influence the way it moves. Still others might let it withstand poison. Urban pollution, traffic and shrinking wild spaces have been causing changes in these genetic instructions. And scientists have been tracking more and more signs of these genetic changes.
        When genes change in response to their environment, it’s called evolution. Some of those changes may leave animals and plants better suited to their homes. It may offer new traits that increase the odds of surviving long enough to reproduce. This means the individuals will pass on these new traits to their offspring. Eventually, traits that had once been rare can now become common throughout a population.

    FANS BEG JUSTIN BIEBER TO CANCEL HIS CONCERT IN THE WAKE OF THE MANCHESTER ATTACKS
    By Alex Riccardi - Yesterday at 4:23 pm


    Imagem da questão de Inglês, Universidade Federal dos Vales do Jequitinhonha e Mucuri de Minas Gerais 2017, Interpretação de texto | Reading comprehension

         No one should have to live in fear but right now, in the wake of the Manchester attacks, some teens and young adults are scared. And you have a good reason. Bombs went off just minutes after Ariana Grande's performance in England taking the lives of 22 people and injuring many others. But, it's important to remember that concert venues and staff try to do everything they can to keep the audience members safe.
        Ariana has officially postponed her "Dangerous Woman" until at least the beginning of June, however, there's no telling if she will cancel more shows after that. In the wake of all of this, fans are encouraging Justin Bieber to pull out of his performances in the U.K. The "Sorry" singer is set to headline at the British Summertime Festival on July 2nd. But, fans don't think it's a good idea.
        They have been expressing their concern on social media and even starting the trend, #nopurposetour. One fan wrote, "@scooterbraun please. We're so worried about Justin's Security.... please please cancel Justin's purpose tour #NoPurposeTour." Another fan said, "Justin, please cancel Purpose Tour, we want you to be safe, we want you alive! We love you! #prayersforManchester #NoPurposeTour." This is absolutely heartbreaking. A third Belieber wrote, "#NoPurposeTourUK @justinbieber I don't want you to die, please do something."
        Justin nor his manager Scooter Braun have yet to comment on the whole thing. However, we also must note that Scooter is Ariana's manager too. He definitely has his clients' best interest and their safety in mind. Now that Ariana has canceled some of her upcoming shows, Scooter definitely had a role in that decision. While fans may be scared for Justin, we have a feeling he is in good hands. If there was any chance of a threat or immediate danger, he wouldn't do the performance. However, the music can't be stopped because of evil in this world. Katy Perry, The Chainsmokers, and Lorde have all vowed to continue doing their upcoming shows in the wake of this tragedy.

    ACTIVE TEENS BUILD STRONG BONES FOR LIFE
    Tweens and teens who run, jump and dance may become adults with less breakable bones
    Sharon Oosthoek - May 8, 2017

        As much as a third of an adult’s skeleton will form during adolescence. So the more active someone is during this time, the stronger those bones will become.
        Adolescence is a critical time for growing strong bones. That's especially true between the ages of 10 and 14 in girls, and 12 to 16 for boys. As much as 36 percent of the adult skeleton forms during these four years. But how strong those bones become depends on how active someone had been during those formative years. That’s the finding of a new study.
        "The bigger the bones children make when they are young, the harder it will be to break when they get older," explains Laura Tosi. She’s a doctor who was not involved in the new work. But she knows the topic well. Tosi directs the Bone Health Program at Children’s National Medical Center in Washington, D.C.

    THE "13 REASONS WHY" ACTORS HAD THERAPY DOGS TO HELP WITH EMOTIONAL SCENES By Hannah Orenstein - Apr 17, 2017 

    Imagem da questão de Inglês, Universidade Federal dos Vales do Jequitinhonha e Mucuri de Minas Gerais 2017, Interpretação de texto | Reading comprehension

        “13 Reasons Why” doesn't shy away from tackling heavy issues like bullying, rape, and suicide. But bringing such dark stories to life can take a toll on actors, which is why the cast had access to cute, cuddly therapy dogs while filming the show.
        "They had therapy dogs on set," Dylan Minnette, who played Clay, told PopSugar. "There was a puppy per hour. They really tried to help out. The puppies helped." According to the Alliance of Therapy Dogs, the pups are "on a mission of sharing smiles and joy."
        Dylan also acknowledged that Katherine Langford, who played Hannah, had the most intense experience of them all. "She had the brunt of the emotional stuff," he continued. "I mean, we all have very emotional parts, but this is about her character." In the same interview, Katherine acknowledged the intensity of her character's role and explained why it was so important to bring these tough scenes to life.
        "We always read a new script at a table read, and once we hit episode nine, there was silence," she said. "That's when we realized what we were doing was important. That's the moment that's kind of ingrained in my head as, 'This is really important.' We cover so many intense issues. I feel like so much of Hannah's life, especially the last five episodes, is so tragic that you just have to put that shock aside and get through it. It's only been after the show and after wrapping that I've gone, wow, we really did handle some really heavy stuff. I'm really proud of how we handle it, because as you said we don't shy away from them."

    The $900bn question: What is the Belt and Road initiative? 

    By Tom Phillips              https://www.theguardian.com               Acessado em 25/10/2017


       It’s a confusing title but it could turn out to be the largest ever infrastructure project with close to a trillion dollars being invested across the globe

       In concrete terms, the Belt and Road initiative is an immensely ambitious development campaign through which China wants to boost trade and stimulate economic growth across Asia and beyond. It hopes to do so by building massive amounts of infrastructure connecting it to countries around the globe. By some estimates, China plans to pump $150bn into such projects each year. In a report released at the start of this year, ratings agency Fitch said an extraordinary $900bn in projects were planned or underway.

       The Belt and Road initiative has two main prongs: one is called the ‘Silk Road Economic Belt’ (the belt) and the other the ‘21st Century Maritime Silk Road’ (the road). Bewilderingly, the ‘road’ is not actually a road but rather a sea route linking China’s southern coast to east Africa and the Mediterranean. The ‘belt’ is a series of overland corridors connecting China with Europe, via Central Asia and the Middle East.

    What the World Needs Now

    Lyrics by Hall David


    What the world needs now is love,

    sweet love It’s the only thing that there’s just too little of

    What the world needs now is love,

    sweet love, No not just for some but for everyone.


    Lord, we don’t need another mountain,

    There are mountains and hillsides enough to climb

    There are oceans and rivers enough to cross,

    Enough to last till the end of time.

    Can plants hear?
    Flora may be able to detect the sounds of flowing water or munching insects

        Pseudoscientific claims that music helps plants grow have been made for decades, despite evidence that is shaky at best. Yet new research suggests some flora may be capable of sensing sounds, such as the gurgle of water through a pipe or the buzzing of insects.
        In a recent study, Monica Gagliano, an evolutionary biologist at the University of Western Australia, and her colleagues placed pea seedlings in pots shaped like an upside-down Y. One arm of each pot was placed in either a tray of water or a coiled plastic tube through which water flowed; the other arm had dry soil. The roots grew toward the arm of the pipe with the fluid, regardless of whether it was easily accessible or hidden inside the tubing. “They just knew the water was there, even if the only thing to detect was the sound of it flowing inside the pipe,” Gagliano says. Yet when the seedlings were given a choice between the water tube and some moistened soil, their roots favored the latter. She hypothesizes that these plants use sound waves to detect water at a distance but follow moisture gradients to home in on their target when it is closer.
        The research, reported earlier this year in Oecologia, is not the first to suggest flora can detect and interpret sounds. A 2014 study showed the rock cress Arabidopsis can distinguish between caterpillar chewing sounds and wind vibrations – the plant produced more chemical toxins after “hearing” a recording of feeding insects. “We tend to underestimate plants because their responses are usually less visible to us. But leaves turn out to be extremely sensitive vibration detectors,” says lead study author Heidi M. Appel, an environmental scientist now at the University of Toledo.

    Can plants hear?
    Flora may be able to detect the sounds of flowing water or munching insects

        Pseudoscientific claims that music helps plants grow have been made for decades, despite evidence that is shaky at best. Yet new research suggests some flora may be capable of sensing sounds, such as the gurgle of water through a pipe or the buzzing of insects.
        In a recent study, Monica Gagliano, an evolutionary biologist at the University of Western Australia, and her colleagues placed pea seedlings in pots shaped like an upside-down Y. One arm of each pot was placed in either a tray of water or a coiled plastic tube through which water flowed; the other arm had dry soil. The roots grew toward the arm of the pipe with the fluid, regardless of whether it was easily accessible or hidden inside the tubing. “They just knew the water was there, even if the only thing to detect was the sound of it flowing inside the pipe,” Gagliano says. Yet when the seedlings were given a choice between the water tube and some moistened soil, their roots favored the latter. She hypothesizes that these plants use sound waves to detect water at a distance but follow moisture gradients to home in on their target when it is closer.
        The research, reported earlier this year in Oecologia, is not the first to suggest flora can detect and interpret sounds. A 2014 study showed the rock cress Arabidopsis can distinguish between caterpillar chewing sounds and wind vibrations – the plant produced more chemical toxins after “hearing” a recording of feeding insects. “We tend to underestimate plants because their responses are usually less visible to us. But leaves turn out to be extremely sensitive vibration detectors,” says lead study author Heidi M. Appel, an environmental scientist now at the University of Toledo.
