Does Fame Drive You Crazy?

    Cold weather during winter months may keep many people from leaving home and running in the open air.

    However, a new study shows that the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather helps improve one's performance.

    Many people say running in the winter can be difficult. Two reasons are the low temperatures and bitter winds. Yet many runners might find it easier than running in hot weather.

    That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body's dehydration (脱水) levels are lower than in warmer conditions. The body needs less water on a cold day than in warm weather.

    This information comes from sports scientists at St. Mary's University in London. John Brewer is a professor of applied sport science at St. Mary's.

    For this study, he and other researchers put a group of people into a room they called an “environmental chamber.” The researchers then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. Brewer says he and his team recorded biological measurements of the runners.

    “We've got a group of subjects into the environmental chamber, we've changed the conditions to replicate the summer or winter and we've got them to run a 10km under both of those conditions and taken various measurements on each runner while they've been completing their 10km.”

    Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating. The body loses heat through droplets of sweat. He says the body also loses heat by transporting the blood to the surface of the skin.

    Siblings refer to one's brothers and sisters. We're attached to siblings as adults far longer than we are as children. Our sibling relationships, in fact, are the longest-lasting family ties we have.

    “Paul, my younger brother, and I, kind of annoyed each other when we were kids,” said Anna, an interviewee, “But as adults, we've always had each other's back, especially when dealing with our mother's health crisis. Paul is the first person I want to talk to when something worries me.”

    There's probably a biological explanation for the close bond of the sibling relationship. Siblings share half their genes, which biologists say should be motivation enough for each other's devotion.

    One thing that can weaken closeness in adulthood is a parent who played favorites in childhood; this sense of hatred can last a lifetime. The simple concept of parental favoritism was enough to shake their relationship.

    “What Paul and I are pretty sure is our parents treated us the same when we were growing up. Yet we're very different people,” Anna said,“ Paul is outgoing while I'm shy. Paul is an amateur pianist while I can't read music or carry a tune. In families with more than one child, every sibling seems to get a label in contrast to every other sibling.”

    The very presence of siblings in the household can be an education. When a new baby is born, the older sibling gains social skills by interacting with the younger, and the younger gains cognitively（认知角度地）by imitating the older. They learn from the friction between them, too, as they fight for their parents' attention. Mild conflict between brothers and sisters teaches them how to interact with friends and co-workers for the rest of their lives.

    It's so sad when things between siblings fall apart, which happens when aging parents need care or die — old feelings of contradiction and jealousy erupt all over again. Many families get through their parents' illnesses just fine, establishing networks where the workload is divided pretty much equally. But about 40 percent of the time there is a single primary caregiver who feels like she is not getting any help from her brothers and sisters, which can lead to serious conflicts.

    Throughout adulthood, the sibling relationship “is powerful and unchanged,” said Jane Mersky Leder, author of the new e-book The Sibling Connection. Whether we are close to our siblings or distant, she writes, they remain our brothers and sisters — for better or for worse.

    So remember the immortal（永恒的）words of folksinger Loudon Wainwright Ⅲ, in a song called Thanksgiving.“ On this brilliant occasion, this special family dinner, if I argue with a loved one, please make me…”

    When we see a person in trouble, the first idea that comes to our mind is to lend a hand. But what if we see an animal in trouble, does the same rule apply?

    This question was raised after a group of penguins were saved from an icy gully（峡谷）in Antarctica. It was filmed for the BBC wildlife series Dynasties. The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young. They built a slope（斜坡）so that a few of the penguins could save themselves.

    The case has taken the international media by storm. Viewers watching this film let out a sigh of relief. "I'm so glad. I understand not taking action directly, but a helping hand isn't bothering, right?" viewer Kathryn Shaw said on her Facebook.

    However, others think human interference（干涉） is unnatural. "You can't have sunshine throughout your life. To have done anything else would only make matters worse," said the show's creator David Attenborough, according to The Times.

    In this case, however, Mike Gunton, the executive producer of the series, said that this was a one­off situation. "There were no animals going to suffer by interfering. You weren't touching the animals and it was just felt by doing this... they had the chance not to have to keep slipping down the slope," he told the BBC.

    Such cases are familiar to Paul Nicklen, wildlife photographer for National Geographic. He told Metro, "If it's ever a predator（捕食者）situation, no matter how gut­wrenching, you stay out of the way. Even when you're watching a male polar bear eat a baby bear."

    "There's no rule book in those situations. You can only respond to the facts that are right there in front of you," Will Lawson, the show's director, told Daily Mail.

    Here's the story of my growth over the past year. If anyone is inspired (激励) by this, that's wonderful.

    I'd been stuck as this under-confident, fat and just frightened girl for years and years and years. Since I was a little girl, I'd been stuck like this, and I had lived a life where I'd be afraid of everything. But then it all started changing. Something clicked, and in over a period of 6 months I finally managed to stick to one of my diets, bringing me from overweight straight down to underweight. This proved (证明) that I could change myself.

    One single time, I heard about a public speaking thing going on at my university, and for the first time, I managed to keep up the courage to go there. For the first time I was able to share my story, and able to do it in front of so many people possibly judging (评判) me, and suddenly all the fears about speaking publicly started vanishing. I never felt more confident.

    This taught me I could get rid (去除) of my fears  It was from that point on that my road to change went from a rocky mess to a full-on empty highway.

    Using the fact that I could change, and that I could get rid of my fears, I started working on them one by one. My fear of talking to strangers ,my fear of asking simple questions, my fear of hanging out with people, my fear of being myself... All of them were gone. And I still continue to progress to this day. I've never stopped.

    Researchers in Australia have discovered an effective new method to capture the atmospheric carbon dioxide that is damaging our planet and transform it into something solid, making it much easier to store.

    Carbon capture isn't new, but previous methods call for the gas to be compressed into liquid and then injected underground. Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks. Instead, in a study published in Nature Communications, the group details their sustainable and cost-effective plan for transforming CO₂ into coal.

    This new process involves a liquid metal catalyst(催化剂)that is efficient in conducting electricity. CO₂ gas is dissolved in a container with some liquid. Once electricity charge is introduced, the CO₂ begins to turn into solid pieces of carbon, which can be collected and stored.

    What makes this particularly unique is that the entire process can occur at room temperature. Previous experiments have only shown a gas to solid conversion at extremely high temperature, which made it impossible on a large scale. Now, the researchers are hoping that their work will be used to create even further when it comes to carbon storage.

    In an interesting side benefit, the solid carbon also works as an electrode(焊条), which opens up a world of possibilities. "A side benefit of the process is that the carbon can hold electrical charge, becoming a super battery, so it could potentially be used as a part in future vehicles," explains Dr. Dorna Estrafilzadeh, a researcher. "The process also produces fuel as a by-product, which could also have industrial applications."
