In a world where nearly 6 million fingerprint records of government employees are stolen in one computer hack, and where millions of people are victims of identity theft every year, the next step in cyber security may well be mapping your brain.
Researchers at Binghamton University, State University of New York arc working on a biometric （生物特征 识别的）system that records how your brain reacts to certain images. With a little more polishing, the scientists' brainchild could become the way you get into a safe deposit box, your office or past scanners at the airport. It could replace the password for your online banking, your email or your social media accounts.
They started their project by measuring the brain waves of 30 subjects. The subjects were fitted with a cap that had 30 electrodes （电极）attached to it, and then shown various images and symbols — celebrity faces, words, pictures of food --- on a computer screen in 200-millisecond bursts. The brain\ reaction was recorded.
The idea is that every time a person needs to use a “password", he or she goes through the same procedure, and the results are matched with their first-time reaction. If the "brainprint" is compromised --- like what happened with the fingerprint records --- then the system is merely reset by running another set of images and collecting a different set of brain waves。. "Even if that was stolen, you could just cancel it and record one to something else", says professor Laszlo.
Laszlo and her team have shown that their system can be 100 percent accurate. So one of the more difficult parts of making the system practical already has been overcome. Now, they're spending much time recording accurate brainprints with as few as three electrodes, which could make recording in the future as easy as wearing a pair of special glasses. They're also working with cheaper materials and different methods to see if they can bring the cost down.

Unexpected connection between sleep and academic performance has been recently discovered.
Researchers have found that insufficient sleep and tiredness increase a person's risk of developing severe medical conditions, such as obesity （肥胖症），high blood sugar levels, and heart disease. Now, a new study has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Gross, the university science professor who led the research, was not trying to find the relationship between sleep and grades when he handed out smartwatches to the 100 students in his chemistry class. Instead, the professor hoped the wrist-worn devices, which track a personas physical activity, would show a connection between exercise and academic achievements.
While Grosses data showed no relationship between these two factors, the study found something surprising. As the researchers were analyzing their data, they noticed that there was a linear （线性的）relationship between the average amount of sleep the students got and their results in the course's 11 quizzes, three midterm tests, and the final exam.
Even more interesting, it was not sufficient for students to just head to bed early the night before a test Instead, it's the sleep you get during the days when learning is happening that matters most.
When students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student. "When you go to bed matters," Gross says. “If you go to bed at 10, or 12, or 1 at night, and sleep for seven hours, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours' sleep. So, quantity isn't everything."
Perhaps the most interesting was the huge impact that small differences in sleep patterns had on the students' grades. The overall course grades of students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep. Similarly, students who varied their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtime.
Who knew getting straight AM just required some extra sleep?
1.Based on his original objective, which best describes Professor Gross's research findings?
A.Convincing. B.Complete.
C.Accidental. D.Doubtful.
2.Who were the people taking part in the study?
A.Middle school chemistry students.
B.Volunteers from different universities.
C.University student athletes.
D.Professor Gross's own students.
3.How did Professor Gross's team measure students' academic performance?
A.Making the students wear special watches.
B.Using the students' normal test and quiz grades.
C.Giving the students regular quizzes after class.
D.Using students' university entrance test results.
4.Based on the study's fin dings, who is likely to perform best academically?
A.A student who has a good night's sleep the night before an important test.
B.A student who sleeps from 11 pm to 6 a.m. each day.
C.A student whose normal bedtime varies between 9 p.m. and 12 p.m.
D.A student who sleeps for a total of 7 hours each night.
A newly-married Sweden couple on a four-month honeymoon were hit by a series of natural disasters, such as the Australian floods, Christchurch earthquake and Japanese tsunami.
Stefan and Erika Svanstrom left Stockholm, Sweden, on December 6 and were immediately trapped in Munich, Germany, due to one of Europe’s worst snowstorms. Traveling with their baby daughter, they flew on to Cairns in Australia which was then struck by one of the most fierce cyclones（龙卷风）in the nation's history. From there, the couple were forced to shelter for 24 hours on the cold floor of a shopping centre with 2500 others.
“Trees were being knocked over and big branches were scattered across the streets,” Mr Svanstrom told Sweden’s Expressen newspaper. “We escaped by the skin of our teeth. It was so close an encounter with death.
They then headed south to Brisbane but the city was experiencing massive flooding, so they crossed the country to Perth where they narrowly escaped raging bush fires. The couple then flew to Christchurch, New Zealand, arriving just after a massive magnitude（震级）6.3 earthquake destroyed the city on February 22.
Mrs Svanstrom said, “When we got there the whole town was a war zone.”
“We could not visit the city since it was completely blocked off, so instead we traveled around before going to Japan.”
But days after the Svanstroms arrived. Tokyo was rocked by Japan’s largest earthquake since records began. “The trembling was horrible and we saw roofs fly off the buildings,” Mr Svanstrom said. “It was like the buildings were shaking back and forth.”
The family returned to Stockholm on March 29 after a much calmer visit to their last destination -China. But Mr Svanstrom - who also survived the destructive tsunami that hit southeast Asia in 2004 -said the marriage was still going strong. He added, “I know marriages have to endure some trials （考验）,but I think we have been through most of them. We’ve certainly experienced more than our fair share of disasters, but the most important thing is that we're together and happy.”

As the New Year’s day was coming, my classmates and I decided to do something specially to give our motherland a new-year gift. After a heating discussion, we agreed on carrying out a flash mob singing the song Me and My Motherland at Guangzhou Railway Station. Early that day, they arrived at the station. After setting up the equipments, I took deep breath and began to sing. Meanwhile, my classmates walked towards me from different directions but sang together. Soon the atmosphere gets warmed up. More and more passers-by slowed down and joined in us happily, wave national flags. All the people sang high praise for which we had done.
