A new experiment shows that spending 50 minutes with an active phone pressed up to the ear increases activity in the brain. This brain activity probably doesn't make you smarter. When cell phones are on, they emit energy in the form of radiation that could be harmful, especially after years of cell phone usage. Scientists don't know yet whether cell phones are bad for the brain. Studies like this one are attempting to find it out. The 47 participants in the experiment may have looked a little strange. Each one had two Samsung cell phones attached to his or her head -- one on each ear. The phone on the left ear was off. The phone on the right ear played a message for 50 minutes, but the participants couldn't hear it because the sound was off. With this set-up, the scientists could be sure they were studying brain activity from the phone itself, and not brain activity due to listening and talking during a conversation. After 50 minutes with two phones strapped to their heads, the participants were given PET scans. The PET scan showed that the left side (the side with the phone turned off) of each participant's brain hadn't changed during the experiment. The right side of the brain, however, had used more glucose, which is a type of sugar that provides fuel to brain cells. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that the brain cells there were active -- even without the person hearing anything. That activity, the scientists say, was probably caused by radiation from the phone. Henry Lai, who works at the University of Washington in Seattle, is uncomfortable with the data related to cell phones. Holding a cell phone to your ear during a conversation is "not really safe," Lai told Science News. Lai is a bioengineer at the University of Washington in Seattle. He wrote an article about the new study for a journal, but he did not work on the study.... Question: Why weren't the participants allowed to have a conversation on the phone during the experiment? Options: A: Because that would be too noisy and bad for the experiment. B: Because they really looked strange and no one wanted to talk to others. C: Because they were given PET scans and they lost the ability to talk. D: Because the scientists want to be sure of the accuracy of the experiment.

Article: While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry. Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face. After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions. They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner. Question: Which of the following statements is TRUE? Options: A: The dogs were not all provided with the entire face, B: According to their size, the dogs were given either upper or lower halves. C: The dogs could read even small changes that accountancy facial expressions after some training. D: The dogs couldn't read strangers facial emotions.

Article: When you are at odds with someone close to you, the One-Minute Drill can show you how to express your feelings effectively - and how to listen more skillfully. All it requires is two individuals who are committed to improving their relationship. Set aside at least ten minutes, and then sit facing each other. Decide who will be the Talker and who will be the Listener. It makes no difference, because later you will change roles. How to perform the One-Minute Drill For approximately 30 seconds, the Talker can say anything he or she wants. Your job will be to express your thoughts and feelings. You can discuss problems you've had a hard time talking about. Remember to limit yourself to about 30 seconds. When the Talker finishes, the Listener will summarize what the Talker just said, as well as how the Talker was feeling inside, as accurately as possible. The Talker now gives the Listener a grade between 0 and 100 per cent to indicate how accurate the summary was. If the rating is 95 per cent or more, you can change roles; the new Talker can continue with the same topic or move on to something entirely new. However, if the grade is below 95 per cent, the Talker should point out what the Listener missed or got wrong, and repeat the process until the overall rating is 95 per cent or more. Then you can change roles and repeat the exercise for as long as you both like. How it works Thirty seconds of emotionally charged information is sufficiently challenging for anyone. Express your feelings in strong, clear, direct language, but as your partner will be listening attentively, you won't need to shout, exaggerate or put your partner down. The Listener should sit and listen respectfully without interrupting. Look into your partner's eyes, but avoid using negative body language. If you like, take a few notes. So the Talker might say: "When I come home from work, I feel tired and I need some quiet time. But you tell me I'm supposed to spend time with the kids. This makes me feel frustrated. I work hard and I'm exhausted at... Question: Who is the One-Minute Drill intended for? Options: A: Those who are to act some roles in a certain play for the first time in their life. B: Those who are preparing for the interview in order to make a good first impression. C: Those who have difficulty communicating with their colleagues or family members. D: Those who have troubled relationships with their friends or family members and try to improve them.
