    As data and identity theft becomes more and more common, the market is growing for biometric (生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.

    Researchers from Georgia Tech say that they have come up with a low-cost device (装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence (节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user's typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people's identities, and by extension, whether they should be given access to the computer it's connected to—regardless of whether someone gets the password right.

    It also doesn't require a new type of technology that people aren't already familiar with. Everybody uses a keyboard and everybody types differently.

    In a study describing the technology, the researchers had 100 volunteers type the word "touch" four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

Surfer Dudes to the Rescue!

About 50 feet from shore of the Northern California's Trinidad State Beach, two brothers were fighting for their lives. They had been swept out to sea in a rip current (激流), their mouths barely able to stay above the water. Thick fog made it difficult for beachgoers to see the guys, but the screams were unmistakable. And every second counted. The brothers, ages 15 and 20, were wearing shorts and T-shirts, unsuitable for a November day, let alone the freezing water. Keven Harder, a supervising ranger (巡查员), told the North Coast Journal in nearby Eureka that swimming in such a temperature "takes the fight right out of you."

Luckily, four surfers in wet suits were nearby. Narayan Weibel, Spenser Stratton, and Adrian York, all 16, along with Taj Ortiz-Beck, 15, were on their surfboards riding up and down the coast on five-foot waves when they heard the cries. They turned and saw two bobbing heads and four struggling arms. "We looked at each other and knew these guys were about to drown, " Weibel told the Washington Post.

Weibel, Stratton, and Ortiz-Beck paddled toward the distressed swimmers while York headed to shore to warn someone to call 911. He then dived back in to help his friends.

As the surfers drew close, the brothers were still fighting hard for their lives. "It was pretty stressful, but there wasn't any time to think about it, and that helped me keep my cool, " Ortiz-Beck says.

Ortiz-Beck pulled up alongside the younger brother. Grabbing him under his arms, he raised him up onto his board. Stratton and Weibel, meanwhile, hurried to help the older brother. He was large, 250 to 300 pounds, and he was panicked.

"I told them, 'Calm down—we got you!'" says Weibel. "They thought they were going to die."

York arrived in time to help get the older brother atop the second board. The surfers then paddled several minutes through choppy water to the medical help waiting onshore. The brothers were scared but fine.

"When we get a call like this one, it's usually too late by the time we get there, " says Dillon Cleavenger, a first responder. "I can't say enough about what these boys did. They were willing and prepared to risk their lives."

Scientists may have found a way to reduce shortage of type O blood. Type O is the kind of blood that hospitals most often need. What the researchers are testing is an easier way to make type O blood out of other kinds of blood.

There are four main kinds of blood. Most people born with one of these four: Type A, Type B, Type AB or Type O. Type O can be safely given to anyone. So it is commonly used when a person is injured or sick and has to have blood.

Type O is the most common blood group.But the supplies of it available in hospitals and blood banks are usually limited.This is because of the high demand for it. Type O blood is used in emergencies when there is no time to identify the patient's blood type.

Giving A, B or AB to someone with a different blood type, including O, can cause a bad reaction by the person's defense system. Their immune system can reject the blood. This immune reaction can be deadly.

The differences among blood types are linked to whether or not red blood cells contain certain kinds of sugar molecules.These molecules are found on the surface of the cells. They are known as antigens(抗原). These antigens are found with type A, B and AB blood but not with type O.

More than twenty-five years ago, scientists found that the antigens could be removed to create what they called universal-type cells. They could be removed with chemicals called enzymes(酶). But large amounts of enzymes were required to make the change.

Doctor Henrik Clausen of the University of Copenhagen in Denmark led the study. The next step, he says, is to complete safety tests. The team is working with the American company ZymeQuest to test the new method. If it meets safety requirements(要求) and is not too costly, it could become a widely used life-saving tool to increase the supply of universal blood.

When things get wildly busy in the morning, some students like skipping breakfast to save time. Whether at home, on the way to school or at school eating something healthy for breakfast may help a student get better grades. According to research, the students who ate a healthy breakfast were twice as likely to achieve above average in education as those who didn't.

Are there really many children who do not eat breakfast? The study found that 39 percent of students reported eating break fast fewer than three days in a usual school week.

Health experts suggest that the best breakfast is a mix of complex carbohydrates, protein and fat. This gives your body the energy it needs to think clearly and to remember what it learns. According to research, not all breakfasts are created equal.  The best breakfast should include complex carbohydrates that slowly release energy to the body.

They say eating between 350 and 500 calories in the morning is a good amount of energy to start the day.

A good breakfast is not just helpful to school-aged children. A study from researchers at the University of Toronto in Canada found that a breakfast rich in protein and complex carbohydrates increased performance on short-term and long-term memory. Carbohydrates and protein are especially important because they have a major effect on long-term memory.

A. The answer is yes.

B. Students don't know about it.

C. But they think it may be harmful to their health.

D. But that may be a big mistake for students.

E.We all benefit from eating something healthy in the morning.

F.Some breakfasts are not able to give the brain what it needs to work at its highest level.

G.However, eating too much can also make a person feel tired and unable to think clearly.

Have you seen people who take pictures of food for more than 10 minutes before eating? How about those who beautify their selfie (自拍) so much that they can't be1? There must be one or more who2 in your social media. No matter3they choose to share, they share the best but the most unreal.

Take my friend Chen. Every time we went to a restaurant, she would not take a4 until all the dishes we 5were on the table.Then, she would spend five minutes on6the dishes in a seemingly random but in fact 7order.Then the most important part: taking pictures.After that, she would choose one of the8and click in the filter(滤镜) app.The food eventually looked 10 times more delicious than it really was, but we had no 9to really enjoy it— it all went cold.Actually Chen's real life is much less elegant. For example, she hates to wash the dishes, so she leaves them in the sink for10.

Many people care too much about others' opinions and try too hard to 11 others. They find it hard to be 12 and to accept themselves, and thus they are afraid to show their 13 life on social media.What they are trying to prove is14what they lack in reality.But this will not bring any15 to reality, as they still16 the same old pattern of life.

If they really want an elegant life, they should put more17 into achieving it18fabricating(伪造) it. Being more confident, 19themselves and trying their best to be better is much more meaningful than20 their life on social media.
