In a world where nearly 6 million fingerprint records of government employees are stolen in one computer hack, and here millions of people are victims of identity theft every year, the next step in cybersecurity may well be mapping your brain.
Researchers at Binghamton University, State University of New York are working on a biometric 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.
The started their project by measuring the brain waves of 30 subjects, The subjects were fitted with a cap that had 30 electrodes 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's 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 material and methods to see if they can bring the cost down.

【推荐1】Google announced this week that it’s building 100 self-driving car prototypes and Lloyd wrote a great piece discussing various city and planning implications, questions, and suggestions.
It’s electric!
Google didn’t make a big point of this, but the self-driving cars will be 100% electric.
Their small size would further help on the green front, but one commenter noted to me that the aerodynamics could be much better. Indeed. However, my understanding is that the shape of the vehicle is centered around the laser and radar sensors, maximizing their view.
You can summon the car!
As The Guardian puts it, ＂the car is summoned by a smartphone for pickup at the user’s location with the destination set.＂
A key point that was very quickly mentioned in Lloyd’s post is that the cars only contain ＂two seats, a space for passengers’ belongings, buttons to start and stop, and a screen that shows the route — and that’s about it.＂
The car will have a range of 100 miles
| A．It has no pedals, no steering wheel |
| B．Confused? Don’t worry, this isn’t just for fun. |
| C．The car doesn’t want you to feel too at home |
| D．That would certainly make them much greener than typical cars. |
| E．On a full charge, the car will have a range of 100 miles, which is a lot for a non-Tesla 100% electric car. |
| F．Here are a few more points about the self-driving cars themselves that we thought were pretty interesting. |
| G．I know that’s what we all think of, but I thought that step of the technology was still a long way off. |
【推荐2】For over a decade, Zubin Kanga, a pianist, composer and technologist, has changed the limits of the forms of musical performances. He has both organized and performed shows that have pushed barriers, with motion sensors, artificial intelligence (AI), live-generated 3D visuals and virtual reality among the technological advancements used to unlock new possibilities of music and performances.
Kanga’s approach to employing cutting-edge technology was first informed by the relative limitations of his chosen instrument. “The piano is a very accurate technology,” he says. “From the early 20th century till now it hasn’t really changed at all. It’s an amazing instrument, but it does have certain limitations in terms of the types of sound you can create.”
One of the early works is Steel on Bone, composed by Kanga himself. He performs the piece using MiMU multi-sensor gloves. “I can put up one finger, and that’ll produce a particular sound,” Kanga explains. “And then I can control that sound just by moving my wrist through the air — I can do that with lots of different gestures.”
“For Steel on Bone, I’m actually playing inside the piano with these steel knitting (编织) needles, and getting all these interesting effects on the strings. Then I’m using samples of them. Sometimes I’m using live delays and operating them. The sound can change depending on how my hands are moving. It allows me to make a very theatrical piece, and people can see this immediate connection between how I’m moving — these very big, almost conductor-like gestures through the air — and the way the sound is changing,” said Kanga.
This is just the start, and Kanga goes on to be enthused with the use of motion sensors to make music, the possibilities that AI offers composers as a tool, and how virtual reality could transform performances and more.

【推荐3】Noise created by humans, such as car traffic, quieted by about 30% between late March and early May, 2020, when Governor Greg Abbott closed schools and restaurants across Texas, according to analysis by researchers at Southern Methodist University (SMU).
“There was quite a big change in some areas,” said Stephen Arrowsmith, a seismologist at SMU, who took on the project with a class of undergraduate and graduate students. Arrowsmith and his students looked at data from a dozen seismometers (地震仪) across North Texas. Seismometers are used to detect earthquakes, but they are sensitive to just about everything that makes the ground vibrate, such as strong winds, ocean waves, construction and traffic.
The innovative idea of using seismometers to track urban noise gained popularity last March when Belgian seismologist Thomas Lecocq posted some of his urban noise data from Brussels on Twitter. Lecocq, of the Royal Observatory of Belgium, received such an enthusiastic response from scientists that he launched the group “Lockdown Seismology” online. “It’s where bored seismologists around the world are working together,” Arrowsmith joked.
Arrowsmith hopes his findings will contribute to a growing list of creative ways in which researchers are using seismometers. In his course, Arrowsmith teaches students how seismic stations can help investigators solve crimes, like terrorist bombings, aid scientists in tracking nuclear tests or assist inspectors in investigating accidents, like chemical plant explosions. One potential application of his research is to better understand the shallow layers of Earth beneath cities. “That could be useful in places where there’s a real seismic hazard, like San Francisco or Los Angeles,” he said, “where just knowing what that shallow structure is tells you a lot about how it would respond in a big earthquake.”

【推荐1】Dreams are pictures, sounds and feelings that happen during sleep. According to modern researches, dreaming is an activity of the brain, which occurs when brainwaves are especially fast. In history people have had many explanations for dreams. In ancient Greece dreaming was thought to be a kind of contact with the gods. Sometimes they were regarded as signs of what may happen in the future.
Over the past centuries, many dream theories have come up. The most famous expert on dreaming was Sigmund Freud, an Austrian doctor, who believed that in dreams we acted out our desires and wishes that couldn’t be satisfied in reality.
Everyone dreams while most of the time we cannot remember our dreams. Even blind people dream. They may see images of events that they have experienced before they became blind. On the other hand, a person who was born blind does not see pictures in dreams, but they can hear, smell and taste in them.
Most people cannot control their dreams. They just happen. Very few people experience lucid dreaming. They know exactly that they are dreaming and can even control what happens in their dreams while they are asleep.
People often have the same dreams over and over again. They may be events in your life that have caused problems which you have not solved yet. Nightmares are dreams that are so terrible that you usually wake up. There is medical treatment for nightmares. You can go to a therapist who tries to find out why you have nightmares and how to deal with them.
Some experts think that dreams are full of symbolic messages that mean something which is deep inside us.

【推荐2】For top students from low-income families, applying to colleges is particularly difficult. One approach makes this whole process easier? Provide an adviser for them.
That’s the idea behind CollegePoint, a program to help gifted students go to schools that match their intelligence. When a high school student takes a standardized test—the PSAT, SAT or ACT—and they score in the 90th percentile, and their families make less than $ 80, 000 a year, they get an email from the program offering them a free adviser. The advisers listen, guide and answer students’ questions.
Connor Rechtzigel, an adviser in Minnesota, sees the importance of his role, for research shows that low-income students are far more likely to undermatch because they don’t think they have what it takes to get in and because many don’t even know what schools are out there. He helped high school senior Justice Benjamin, the first in his family to apply to college, thinking about what his ideal learning experience was. Finally, Justice narrowed in on smaller schools where he could study environmental science and made his final choice: Skidmore College in New York.
Figuring out how to pay for college is a major part of what CollegePoint advisers do. Nakhle, an adviser in North Carolina, is working with Hensley, an Ohio high school senior who can’t get extra financial help from her family. They spent a lot of time comparing and analyzing her financial-aid award letters, which made her decision much clearer. Finally, the Ohio State University offered an option where she would pay nothing. Staying in-state wasn’t her first choice, but it was the best option for her.

【推荐3】In the winter of 1664-65, a bitter cold fell on London in the days before Christmas. Above the city, an unusually bright comet (彗星) shot across the sky, exciting much prediction of a snow storm, Outside the city wall, a woman was announced dead of a disease that was spreading in that area. Her house was locked up and the phrase “Lord Have Mercy On Us” was painted on the door in red.
By the following Christmas, the virus that had killed the woman would go on to kill nearly 100,000 people living in and around London—almost a third of those who did not flee.
In The Great Plague (瘟疫), historian A.Lloyd Moote and microbiologist Dorothy C.Moote provide a deeply informed account of this plague year. Reading the book, readers are taken from the palaces of the city’s wealthiest citizens to the poor areas where the vast majority of Londoners were living, and to the surrounding countryside with those who fled. The Mootes point out that, even at the height of the plague, the city did not fall into chaos. Doctors, nurses and the church staff remained in the city to care for the sick; city officials tried their best to fight the crisis with all the legal tools; commerce continued even as businesses shut down.
To describe life and death in and around London, the authors focus on the experiences of nine individuals. Through their letters and diaries, the Mootes offer fresh descriptions of key issues in the history of the Great Plague: how different communities understood and experienced the disease; how medical, religious, and government bodies reacted; how well the social order held together; the economic and moral dilemmas people faced when debating whether to flee the city; and the nature of the material, social, and spiritual resources supporting those who remained. Based on humanity, the authors offer a masterful portrait of a city and its residents attacked by—and daringly resisting -unimaginable horror.

【推荐1】Every two or three months, Thyago Ohana goes out on the busy streets of Vienna with a sign saying “Free Hugs”. The handsome 32-year-old Brazilian, who works in international trade at India’s Vienna embassy, chooses a popular site, like the historic shopping street, Kaemtner Strasse. There he opens his arms to anyone who wants a hearty embrace (拥抱).
He does it because back in 2012, when he was feeling very stressed and anxious during a visit to Paris, a stranger gave him a free hug. He’s never forgotten how it filled him with unexpected calm and joy.
For those who take up his offer, the hug makes them laugh and smile. But sometimes it does more, as when an elderly woman in a tour group stopped and watched him. The group moved on, but she remained and asked, “Can I have a hug?” “Of course you can!” said Thyago who wrapped his arms round her. When they broke their embrace, she kept holding onto his shoulders and looked into his eyes. “Thank you,” she said. “I can’t remember the last time I was hugged this way.”
It’s a memory that still makes Thyago emotional. “It was a really powerful moment of human connection. It’s why I keep doing it.”
Of our live senses, our sense of touch is the one that is most easily taken for granted. “A child can be born blind or deaf and they will grow up just fine,” says David J Linden, author of Touch. The Science of Hand, Heart and Mind. “Yet if a baby is lacking in loving social touch for the first two years of life, then all sorts of disasters unfold.” That’s one reason why when babies are born, they are now usually placed on their mother’s skin.
Linden says however you do it, “maximizing touch in your life is a good thing”— whether holding hands, petting a dog, going to the hairdresser, hugging our kids, our partners or even a stranger.
1. Why did Thyago Ohana offer free hugs to strangers?| A．He longed for calm and joy. |

【推荐2】It was the beginning of another school year. I had agreed to teach all struggling students in need of critical intervention(介入). I knew what lay ahead — tough work hours overlaid with guilt, consumed with essays that needed feedback and lesson plans with best practice strategies. No wonder people always acknowledge my teaching career with, “I'm glad it's you and not me.”
Suddenly, my mind transported me to my first few years of teaching.
“Peter Potter,” I called from my name list, trying to control my laughter. “Laughlin McLaughlin？” Surely these were not real names.
“Emotionally disabled... keeps them separated from the other kids...，” the vice headmaster commanded. This was my first teaching assignment.
Surely this year could never be as discouraging as those first few. In my new classroom, I looked into the face of Jason. At eleven, his mother was killed in an accident, leaving him with physical, academic, and certainly emotional scars. I looked at another student, Robert, standing at the door; my vice headmaster asked if I would take him, even though he was an eleventh grader in my tenth grade class.
But then there were — and are — stories of success — of Dustin, in Graduate School for Electrical and Computer Engineering; of Michael, now a teacher in a city school; of Willie... I thought of the thousands of students whose lives have touched mine far more than I could have ever touched theirs.
I broke from my daydream, a smile spreading across my face. Sadness, tears, challenges, fears — yes, teaching is filled with all of these — yet, it is also filled with laughter and smiles, hope, dreams, and rewards beyond measure.
“I'm glad it's you and not me.” Those words resounded in my mind once again.

【推荐3】I had difficulty in finding work when I was in my twenties. Finally, Seagulls Reuse in Leeds took me on as a volunteer. It's an environmental social enterprise that rescues 400 tonnes of paint from landfill (垃圾填埋池) annually and repurposes it to offer a bespoke (定制的) paint-mixing service. I carved out my own role, mixing paint, working with other volunteers and assisting customers, before being hired as a decorator and full-time member of staff. It wasn't until then, in my late 20s, that I realised I'm colour-blind.
Mixing paint is nothing like the colour wheel you learn at school; blue and green doesn't just make green. You don't even mix different greens to make green paint. It's more technical and complex than that, and there are so many subtle (微妙的) variations.
Dulux and other big companies let machines do all the work, but our process is nothing like that. We can also only use the colours we have in the warehouse that day, so we sometimes have to get creative. They have scientists, but we have our intuition (直觉), years of experience and an essential human touch and eye.
I'm 38 now, and have been at Seagulls for 11 years. I've learned that I struggle most with colours. I see green in dark browns and creams and some reds I see as pink. So, along with the knowledge I've now memorised, I use different skills with customers. I get them involved by explaining how I'm creating their paint and encourage feedback (反馈). That way, we're both helping each other get the perfect result. I write down things I do wrong, so I don't repeat them.
If I tell customers I'm colour-blind, they're always shocked and say they'd never have guessed. I do have a visual problem, but I'm not angry about it and wouldn't change it even if I could. It's made me push myself harder.
1. Why did the author volunteer to work in Seagulls Reuse?| A．It accepted colour-blind staff. |

【推荐1】We will all probably know both some introverts （内向的人）and extroverts （外向的人）in life, and yet we can gain a wrong impression about both types of people. For example, some introverts can be extremely confident and they can be able people. However, some extroverts aren’t as confident as they'd like to appear to be and often try to hide their true identities behind a false appearance.
Shyness can affect both introverts and extroverts and anybody else too. It can be very debilitating （使衰弱的）and, if severe, can have a huge negative influence upon our ability to form meaningful relationships and it can also affect our careers or jobs.
A lot of people feel shy because they have low self-respect and feel unworthy when comparing themselves to others. They find it difficult to communicate with others whom they don't know. In that case, one of the best ways of overcoming the shyness is to focus the attention on the other person instead. Shy people can try changing people's focus on someone else， so that they don't need to talk about themselves too much.
If you recognize that you are shy and see that as a lion in the way of enjoying your life. you should first overcome it by accepting that it's causing a problem for you. Trying getting into conversations with strangers is helpful. Shy people are challenging themselves and over- coming their shyness. In this way, shy people can get their own self-respect. Each time they do it, this will be repeated until they feel confident enough.
Like any negative thought， determination can also help you beat shyness and having a positive attitude is the key to overcoming the shyness.

【推荐2】Two years ago, Kursat Ceylan was in New York to give a talk about disability rights. Blind since birth, the Turkish businessman was struggling to find his hotel, holding a cane (手杖) in one hand and pulling his luggage with the other while trying to get GPS directions from his phone.“Not surprisingly, all ofa sudden I hit a pole," he says. While the cane can tell you what's on the ground, it doesn' t help with objects at the body or head level. It wasn' t the first time Ceylan had run into something, injuring himself.
With WeWALK, a new smart cane, Ceylan hopes to help blind people navigate (设法穿越) their environments more easily. The cane can tell users what's around them. A sensor detects objects at the body or head level and gives a warning vibration (振动). WeWALK users pair the cane with their smartphones and then use the cane's touchpad to access features like voice assistant or navigation.
In the future, Ceylan hopes to connect WeWALK with public transportation and ridesharing services. That way it could tell the user the number of the bus coming down the street or the license plate of the Uber stopping at the roadside. The cane will update with new features as they come online, much the way smartphones do.
Ceylan believes WeWALK can help blind people achieve greater freedom of movement, which will give them greater access to education and jobs. Blind people are less likely to complete higher education and have higher rates of unemployment.“WeWALK is not just a smart cane for us," he says. "It is a movement to increase full and equal participation in social life. "
The cane is already having an impact on users, Ceylan says. He recently received an email from a teacher who had become blind as an adult. He had been depressed, he wrote. But since getting a WeWALK cane,“'It became my antidepressant,' he wrote," Ceylan recalls. "This is the most important feedback that we got," Ceylan says. “We saw that we are touching the real problem."
1. Why is Ceylan' s experience mentioned in Paragraph 1?| A．To support disability rights. | B．To call for care for the blind. |
