Annie slept in the front of the seat with her father drove through the darkness. ”We're almost there!” Dad announced cheerfully. “Soonwell be observing and counting owls at the state park.” Yawning, Annie nodded and smiled. The time was 4:30 a.m. Looking out into the darkness, Annie remembered learning in school that most owls are active at night, when they hunt for food. During the day they sleep in hard-to-find spots.

  “Dad, why do you need to count owls?” she asked. “It's important for the scientists to have current information about bird populations,” he explained. “We want to know which birds have decreased in number and whether any new kinds of birds are coming into a certain area. You and I will write down the kinds of birds that we see today and keep a record of how many times we see each kind. The we'll send out a report to a scientific organization that is collecting about birds from people all over the county.”

    Dad pulled into the parking lot of the state park. Then, with flashing in hand, they began their hike into the woods. Annie zipped up her coat and tried to keep from trembling. She had not expected the morning to be so frigid. Luckily her gloves were in her pocket.

    Suddenly Annie's father stooped and gestured for her to bestill. Obeying, Annie did not take another step. She thought she heard a low crying up head. “That's certainly a screech owl,” her father whispered. “Let's get a look at it.” After looking more closely, Annie could see that it was asmall owl. Sensing danger, the owl narrowed its eyes and pulled its feathers tightly against its body. Annie carefully wrote down in her notebook that they had seen a screech owl.

    Walking a little farther, they came to a tall oak tree. “This looks like a perfect spot to attract owls,” Dad said. “I'm going to play a recording of common call of the barred owl. Maybe we can get one to answer." Annie could hardly believe her ear. The recorded all sounded as if the birds were asking, “who cooks for you?” Moments later Annie thought she heard areturn call in distance. She held her breath and waited. Suddenly a huge birdlanded very quietly on a branch above them.

    Annie had long forgotten how cold it was. She stood in wonder, shining her flashlight on the bird and studying it carefully. The barred owl was nearly tow feet tall. Gray feathers surrounded its dark eyes. The bird did not matter. Annie would never forge the image of the powerful barred owl.

    Starting the day on an egg could keep your blood pressure under control, research suggests. Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressure-lowering drugs.

    The research, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes (酶) they produce a protein that acts in the same way as Ace inhibitors, but more work is needed to show the effects outside a lab and in the human body.

    Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to work on an egg. They concluded that the type of cholesterol (胆固醇) found in eggs has little effect on increasing heart disease risks.

    Researcher Professor Bruce Griffin, from the University of Surrey, said, "The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected. The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs. The UK public do not need to be limiting the number of eggs they eat. They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods."

    The British Heart Foundation dropped its three-egg-a-week limit in 2005. However, almost half of Britons believe the limit still applies.

    Eating healthy 100% of the time can seem like a near impossible goal. But along with consistent exercise, healthy eating will make you feel better, give you more energy, and help you perform better in your workouts. {#blank#}1{#/blank#}

    Here are some tricks to make healthy eating easy:

    ● {#blank#}2{#/blank#}

    Protein is what keeps you full, fuels your muscles, and helps you keep a strong and slim figure. Starting your day out with around 30 grams of protein will not only help get you through the morning without feeling hunger pains, it will also help you get less desires for sugar and carbs(碳水化合物)later in the day.

    ●Make veggies a main part of every meal

    {#blank#}3{#/blank#} You'll find that you might actually start to like vegetables, and your body will start to want them because of how good they make you feel after eating them.

    ●Eat whole foods whenever possible

    Simply focus on avoiding processed foods and include as many whole foods as possible in your diet. {#blank#}4{#/blank#} But once you discover how food is supposed to taste, eating healthy will become much more natural to you.

    ●Don't deny yourself your favorite foods

    {#blank#}5{#/blank#} Because it'll cause you to feel bitter, more often leading to a binge(大吃)eating session. So if you're working out and keeping active on a regular basis, allowing yourself a few small treats every once in a while will not only make you happier, it will also make it more likely that you'll stick with healthy eating in the long run.

A. So want exactly are whole foods?

B. It may take a little to get used to

C. And it doesn't have to be that difficult

D. Limit them, but don't cut them out altogether

E. There are so many good ones to choose from

F. Eat a protein-packed breakfast every morning

G. Make them a main part of every meal, at least two thirds of your plate as often as possible

The weather is getting hotter and you'll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you pour down your throat. Something that looks cool may not be good for your health.

    There are plenty of so-called energy drinks on the market. Most of them have an attractive colour and cool name. Their nutrition list also contains various things from vitamins to ginseng. Sounds great!

    But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.

    Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

    Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.

    Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 percent of boys aged 8-12 take in more caffeine than their parents.

    There are potential health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.

    Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.

    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.
