Flu easily spreads from one person to another. This is especially true to people who are weak. If you are weak, you are more likely to catch flu easily. Do you know how you can avoid flu?

    Keep in good health

    The best antidote (解药) to illness is good health. You can eat everything you want but make sure that your diet is healthy. The healthier you are, the better for you to avoid any type of illness around. Most doctors suggest plenty of fresh fruit juice and water in order that one can avoid flu.

    Stay away from people with flu

    If a member of the family or a friend has flu, stay away from them until they are well. Flu is very communicable and you can catch it by going with the person with flu. Wear a mask (面罩) and avoid using things that the person with flu is using.

    Exercise

    Exercising will make you stronger which means a stronger immune (免疫的) system too. Exercise often so that your body will keep healthy. It doesn't matter what kind of exercise.

    What is important is you are making your body stronger to prevent illness from attacking you.

    Be happy

    Happy people are healthy people. Their life is stress-free, so they are more likely to be safe from illness. If you are unhappy, which affects your immune system, you will easily get sick.

    Avoiding the flu is easy. Just boost (增强) your immune system and it will take care of the rest.

    The female dog, who Leonard appropriately named Gobi, joined Leonard on the second day of the annual 4 Deserts Race Series and ran side-by-side with him for 77 miles. Leonard noticed Gobi running with 101 runners during the first day, but on the second day, Gobi was on the start line, looking up at him. "This was the first contact I had with her and as I ran off the line I noticed her by my side," he said. "I didn't speak much to her that day, but at the finish line she followed me into the tent and we slept next to each other. That was it then."

    Leonard shared his sleeping space, water and food with his small companion during the race. He even lent her a hand when needed. "I carried her across rivers that she could not cross on her own," he wrote on his Crowdfunder page.

    After the race, it was clear to Leonard that he had developed a special bond with the pup and started researching ways to get Gobi to the UK. He learned that it would take four months for Gobi to be medically checked and cleared for entry, all of which will cost $6,560 USD, an amount that has been surpassed(超过) due to a successful Crowdfunder campaign that raised $13,330 USD.

    Empathy is the ability to share and understand the emotions of others. It is a construct of multiple components, each of which is associated with its own brain network. New research has found empathy may have a genetic component that affects personality, and cognition, psychiatric (relating to mental illness) conditions. The findings are highlighted in a new study led by researchers at the University of Cambridge, the University Paris Diderot and the Institute Pasteur, and 23andMe.

    Published yesterday in Molecular Psychiatry, the first study found evidence that genes influence our ability to read and understand emotions in others. The team at the Autism Research Centre at the University of Cambridge analyzed data from 89,000 individuals worldwide, the majority of whom were 23andMe customers, who were willing to be researched.

    Participants completed a “Reading the Mind in the Eyes Test”, in which they were shown photos of the area around the eyes and asked to identify one of two possible emotions. This assessed Theory of Mind and the ability to recognize and appreciate another person's mental state. Researchers identified that women with certain genetic variants（变异）on chromosome（染色体）3 performed better, with higher levels of empathy. Interestingly, male performance on the test was not associated with a genetic variant. Overall, women consistently performed better than men, exhibiting higher levels of empathy.

    The genetic variant associated with empathy in women is near the gene LRRN1(Leucine Rich Neuronal 1) on chromosome 3, which is highly active in an area of the human brain. Brain scans have indicated that this section of the brain may play a role in cognition empathy.

    This is also the unprecedented study that relates measures of empathy with variation in the human genome（基因组）. Previous research that has attempted to assess the genetic associations of personality and psychological traits has sometimes been unreliable, due to their small sample size. 23andMe's large data offering enables scientists to gain insight into the biology behind features such as empathy.

    23andMe is committed to furthering such research and approximately 85 percent of customers agrees to allow their de-identified（去识别的）data to be made available for study. By allowing scientists access to its unique and powerful research resource engine, 23andMe helps open up genetics to qualified researchers, providing novel insights into individuals' features, genetic diseases and a variety of other conditions.

    Do you ever pull your phone out of your pocket, thinking it is vibrating(振动), only to find that it isn't? This phenomenon, which scientists call "phantom(幻觉的)phone vibration", is very common. Around 80% of people surveyed say they have imagined their phones vibrating when they were actually still.

    So, what leads to this universal behavior? According to the BBC, the explanation lies in your brainˈs ability to discover signals from the outside world. When your phone is in your pocket, there are two possible states: it is either vibrating or not. Meanwhile, you also have two possible states of mind: the judgment that the phone is vibrating, or that it isn't. Ideally, you match the four states correctly.

However, sometimes your brain decides that the results of missing a call are more serious than a "false alarm". Therefore, you become more sensitive(敏感的) to vibrations so that you don't miss anything. This is just like the fire alarm in your home—it can be annoying when it goes off in response to just a tiny bit of smoke. But that's a small price to pay compared to a fire really breaking out because the alarm fails to alert you. Now, you might still ask: why can't our brains just make every judgment correctly without being too sensitive to false signals? The answer is that your brain bears a heavy burden every day. "You get a large amount of sensory(感觉的) information that's coming from your eyes, ears and skin, and you can't deal with all that information all the time, "Michael Rothberg, a researcher at Baystate Medical Center in Springfield, US, told Live Science.

    For example, the rustling(沙沙声)of clothing or the growling(咕咕声)of your stomach may both lead your brain to believe that they come from the vibration of your phone-it is like trying to hear your name being called in a noisy room.

    So, perhaps you should just check your phone whenever you think it's vibrating. It's not too much trouble to do that, is it?

    Drive through any suburb in the U.S. today, and it's hard to miss the bins that have become companions to America's trash cans. Recycling has become commonplace, as people recognize the need to care for the environment. Yet most people's recycling consciousness extends only as far as paper, bottles, and cans. People seldom find themselves facing the growing problem of e-waste.

    E-waste rapidly increases as the techno-fashionable frequently upgrade to the most advanced device and the majority of them end up in landfills (垃圾填埋地). Some people who track such waste say that users throw away nearly 2 million tons of TVs, VCRs, computers, cell phones, and other electronics every day. Unless we can find a safe replacement, this e-waste may get into the ground and poison the water with dangerous toxins (毒素), such as lead, mercury, and arsenic. Burning the waste also dangerously contaminates the air.

    However, e-waste often contains reusable silver, gold, and other electrical materials. Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals, which can destroy ecosystems.

    A growing number of states have adopted laws to ban dumping (倾倒) e-waste. Still, less than a quarter of this waste will reach lawful recycling programs. Some companies advertising safe disposal (处置) in fact merely ship the waste to some developing countries, where it still ends up in landfills. These organizations prevent progress by unsafely disposing of waste in an out-of-sight, out-of-mind location.

    However, the small but growing number of cities and corporations that do handle e-waste responsibly represents progress toward making the world a cleaner, better place for us all.
