Most people will answer a ringing phone. Usually you don't know who is phoning or how urgent their business is, so a ringing phone is difficult to ignore. In one experiment, a researcher wrote down the numbers of several public phones in stations and airports. Then he called the numbers. Someone nearly always answered. When he asked why, people usually said, “Because it rang.”

A few years ago in New Jersey, a man with a rifle killed 13 people. Armed police surrounded his house but he refused to come out. A reporter found out the phone number of the house and called. The man put down his rifle and answered the phone. “What do you want?” he said, “I'm really busy right now.”

    Imagine you're at work and the phone is ringing in someone else's office. Do you answer it or not? In one survey on telephone use, 51% of participants told researches that they did. We can't ignore the phone and for the reason, it forces its way into our lives. It interrupts what we are doing and on top of that, the caller is often someone we don't really want to talk to. However, in the survey, 58% said they never took the phone off the hook, and 67% didn't mind if someone called during a television programme. For 44% it wasn't a problem if someone rang during a meal, while only 28% were annoyed or upset. If someone phoned in the middle of the night, 40% told researchers that they got nervous or frightened, while around 30% got angry.

    Of course, when someone is really annoying, you can choose to hang up on him/her. This is in fact one of the rudest things you can do on the phone, but 79% said they were prepared to do it in some cases. Only 6% told researchers they never hung up on people.

    Listening looks easy, yet hard to master. Don't worry. Here we've collected four books to help you to be a good listener.

    The Good Listener by James E. Sullivan

    The book points out how our poor listening hurts others and how much we can heal（使……好受些）a person just by listening and understanding his/her feelings. It also gives suggestions on how we can improve our listening and how we can share so others will understand us better.

    Just Listen by Mark Goulston

    This book is about listening and giving responses. Just Listen is a good how-to guide to becoming a better face-to-face communicator. It reveals（揭露）how to make a powerful first impression, how to respond positively and more. If you deal with difficult people around you, this is a must-read for you to not only understand them but also make them feel understood.

    Power Listening by Bernard T. Ferrari

    Poor listening can lead to poor business decisions. The book focuses on corporate（团体的）listening. It's great for anyone who leads groups through decision and design. The author offers a step-by-step guide to turn readers into active listeners.

    The Lost Art of Listening by Michael P. Nichols

    What is it that keeps so many of us from really listening? Nichols answers the question. The book is filled with real-world examples that show easy-to-learn techniques for becoming a better listener. The techniques enable us to break through misunderstandings and conflicts in our relationships.

    An idea that started in Seattle's public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.

    In addition to encouraging reading as a pursuit (追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched (发起)the "If All of Seattle Read the Same Book" project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.

    In Chicago, the mayor(市长)appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighbourhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.

    The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity(一致)can be achieved. Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.

    Ultimately as Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process or have enjoyed speaking to someone with whom they would not otherwise have shared a word.

    Donna Strickland is a professor in the Department of Physics and Astronomy. Professor Strickland is one of the recipients(受领者) of the Nobel Prize in Physics 2018 with Gérard Mourou, her PhD supervisor at the time. They published this Nobel-winning research in 1985 when Strickland was a PhD student at the University of Rochester in New York state. Together they paved the way toward the most intense laser pulses ever created.

    Professor Donna Strickland is only the third woman ever to have won a Nobel Prize in physics. She and her fellow winners were honored for what the Nobel Committee called ground-breaking inventions in laser physics. Professor Strickland devised a way to use lasers as very precise drilling or cutting tools. Millions of eye operations are performed every year with these sharpest of laser beams.

    "How surprising do you think it is that you're the third woman to win this prize?"

"Well, that is surprising, isn't it? I think that's the story of Maria that people want to talk about — that why should it take 60 years? There are so many women out there doing fantastic research, so why does it take so long to get recognized?"

    Physics still has one of the largest gender gaps in science. One recent study concluded that at the current rates it would be more than two centuries until there were equal numbers of senior male and female researchers in the field.

    The last woman to win a physics Nobel was German-born Maria Goeppert-Mayer for her discoveries about the nuclei of atoms. Before that it was Marie Curie, who shared the 1903 prize with her husband, Pierre. This year's winners hope that breaking this half century hiatus will mean the focus in future will be on the research, rather than the gender of the researcher.

    We all need to eat. So, meals could be a chance to stop what we're doing and spend time with the people in our lives. A recent study from a team of South Korea suggests that eating together has many good effects on children and teenagers while frequently eating alone may lead to poor eating habits and poor food choices. People who eat alone more than twice a week have a greater risk of developing high blood pressure.

    There are benefits of family dinners on children and teenagers.

    In 2014, the Organization for Economic Cooperation and Development (OECD) looked at data from nearly three-quarters of the world's countries. Among its findings is the fact that students who share a main meal with their families are less likely to hate school. Children who eat a main meal with their families are also less likely to take drugs (毒品).

    In the report, titled "The Importance of Family Dinners (VIII)," researchers say that teens who have frequent family dinners are more likely to say their parents know a lot about what's going on in their lives.

    Another study from the University of Montreal finds that children who eat with their families experience long-term physical and mental health benefits. These children are physically in better shape and drink fewer sugary soft drinks. These children also seem to have better social skills and are less violent.

    One of the researchers, Pagane, involved in this study is a professor at the university. She says that mealtimes with parents possibly provide young children with firsthand social events, which helps them have better communication skills.

    Almost every second of every day an older adult falls in the United States. That's approximately 29 million falls per year and nearly 27, 000 deaths, according to the Centers for Disease Control and Prevention.

    Still in the stating stage, the Active Pelvis Orthosis (APO) system in Switzerland wants to make a lightweight, wearable exoskeleton (外骨骼) that could detect signs of balance loss and assist with balance recovery to keep the elderly wearer from falling, only when needed.

    Other exoskeletons, either in development or on the market today, assist with movement and make heavy objects feel lighter. Mobility-impaired people can walk again. But none of these devices predict what the wearer is going to do next and take measures to correct an unsteady move.

    The 3 kilogram (6.7 pound) exoskeleton was built entirely from scratch by the research team and is designed to be worn on the lower half of the body. A waistband connects to two movable carbon fiber braces (支架), each one positioned on the outer side of a leg. Tiny motors and so-called "adaptive oscillators" (适配振荡器) in the computer circuits use a special process to detect the, wearer's unique paces. That part takes just a few minutes.

    While wearing the exoskeleton, a person may feel the braces and the motors pushing slightly on their legs. If their paces go against normal, the motors create a force in the braces that cause them to stiffen up and push a little more strongly against the legs, which provides stability.

    In the next three years, the APO hopes to develop something that is commercially available.
