1 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

3 . Jenifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's degree.
Mauer, of Edgar, Wisconsin, grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition(学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.
Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing. She chose the UW-Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four-year degree close to home. She could drive to class and be home in the evening to help with her kids. Jenifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her 68-year-old mother helped take care of the children at times.
Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed(牺牲)to achieve her goal, giving up many nights with her kids and missing important events to study. ''Some nights my heart was breaking to have to pick between my kids and studying for exams or papers,'' she says. However, her children have learned an important lesson witnessing their mother earn her degree. Jennifer is a first-generation graduate and an inspiration to her family-and that's pretty powerful.

4 . I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.
I got a rescue call from a woman in Muttontown. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2-to 3-week-old owl. It had already been placed in a carrier for safety.
I examined the chick(雏鸟) and it seemed fine. If I could locate the nest, I might have been able to put it back, but no luck. My next work was to construct a nest and anchor it in a tree.
The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.
Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.
A nervous night to be sure, but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all — LUNCH! The parents had done their duty and would probably continue to do so.

5 . As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.
In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.
In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory (交互记忆)”
According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn’t mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

6 . My daughter was being thrown out of the sixth grade. The teacher said, “She may not be up to what we’re trying to accomplish.” He was really saying she didn’t have the intelligence. I got mad because I knew she was smart, just as my father had known I was smart when I was failing in school. We had her tested. I decided to get myself tested as well, and found that the troubles she was having were exactly what I had had — dyslexia. By then I was a successful television writer, and had won an Emmy Award for “The Rockford Files.”
If I had known earlier that something beyond my control could explain why I was a low achiever, I may not have worked so hard in my late 20s and early 30s. I was writing and writing. I was working for no other reason than to hear people praise me, because I did badly in all my courses.
I once asked a friend who had always gotten an A, “How long did you study for this?” He said, “I didn’t. I just glanced at it.” So he must be smarter. I began to ask, “What will happen to me when I’m not good at anything?” Despite my doubts, I did become successful, and people now say to me, “So you’ve overcome dyslexia.”
No. You don’t overcome it, you learn to compensate for it. Some easy things are very hard for me. Most people who go through college read twice as fast as I do. I avoid dialing a phone if I can, because I sometimes have to try three times to get the number right.
Despite my weaknesses I view dyslexia as a gift, not a curse (诅咒). Many dyslexics are good at right-brain, abstract thought, and that’s what my kind of creative writing is. And I can write quickly, and can get up to 15 pages a day. Writing is my strength.
The real fear I have for dyslexic children is not they have to struggle in school, but that they will quit on themselves before they get out of school. Parents have to create victories for them, whether it’s music, sports or art. You can make your dyslexic child able to say, “Yeah, reading is hard. But I have other things I can do.”

7 . A strong coffee after a poor night's sleep is the kick-start many people need in the morning but new research suggests that it might be best to have a bite to eat first.
A study has found that drinking coffee first can have a negative effect on blood sugar control - a risk factor for diabetes （糖尿病）and heart disease.
“We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee --- subjectively the more tired we feel, the stronger the coffee,“ said Professor James Betts, at the University of Bath in the UK.
For their study, researchers at the University of Bath got 29 healthy men and women to take part in three different overnight experiments, with at least a week between them.
In one, the participants had a normal night's sleep, roughly from 11 p.m. to 7 a.m., and were asked to consume a sugary drink on waking in the morning. They then experienced an interrupted night's sleep, where the researchers woke them every hour for five minutes by sending them text messages to which they had to respond — and upon waking were given the same sugary drink.
On another night, participants experienced the same sleep interruption, but this time were first given a strong black coffee 30 minutes before consuming the sugary drink.
They found that one night of interrupted sleep did not worsen the participants' blood sugar and insulin （胰 岛素）responses when compared to the normal night's sleep-- although previous research suggested that losing many hours of sleep or many nights of poor sleep could have a negative effect. However, strong black coffee consumed before breakfast actually increased the blood sugar response by around 50% — suggesting that relying on coffee after a bad night to stop feeling sleepy could limit your body's ability to tolerate the sugar in your breakfast.

10 . Scientists have developed a new type of smart bandage (绷带) that can signal the type of bacterial (细菌的) infection it’s protecting, just like a traffic light, as well as release the right type of drugs on demand. The traffic light system works just like this: Green means no bacteria or a low concentration of bacteria, yellow means drug-sensitive (DS) bacteria responsive to standard antibiotics (抗生素) and causes antibiotic release, and red means drug-resistant (DR) bacteria that need extra help to be wiped out.
In testing the bandage on mice, the research team was able to successfully treat both DS and DR infections using the new method. However, the common methods of sensing resistance are limited by time, the requirement for professional personnel, and expensive instruments. Moreover, the abuse of antibiotics causes the accelerated process of bacterial resistance.
It’s easy to see how a simple bandage and light could overcome some of these limitations. Treatment doesn’t have to wait for a doctor to make a diagnosis, and the bandage can get the right sort of drugs applied at the earliest opportunity. What’s more, the person wearing the bandage gets real-time feedback on what’s happening with the infection, if there’s an infection at all. The researchers say it offers numerous benefits over existing treatments that make use of light, including photodynamic therapy or PDT.
We’ve been seeing quite a few upgrades to the traditional bandage in recent years, thanks to advances in science — like the nanofiber mesh that attracts bacteria and draws some of it out, speeding up the healing process. Then there’s the novel bandage for treating burns, which stops bacteria from multiplying and lowers the risk of infection.
The more work that a bandage can do while it’s protecting a wound, the better. Efforts to improve bandages continue and now we've got a bandage that not only releases antibiotics, but also tells the patient exactly what’s going on too.
