You are the collector in the gallery of your life. You collect. You might not mean to but you do. One out of three people collects tangible（有形的）things such as cats, photos and noisy toys.

    There are among some 40 collections that are being shown at “The Museum Of”—the first of several new museums which, over the next two years, will exhibit the objects accumulated by unknown collectors. In doing so, they will promote a popular culture of museums, not what museums normally represent.

    Some of the collections are fairly common—records, model houses. Others are strangely beautiful—branches that have fallen from tree, for example. But they all reveal （显露）a lot of things: ask someone what they collect and their answers will tell you who they are.

    Other on the way include “The museum of Collectors” and “The Museum of Me.”These new ones, it is hoped, will build on the success of “The Museum Of.” The thinkers behind the project want to explore why people collect, and what it means to do so. They hope that visitors who may not have considered themselves collectors will begin to see they, too, collect.

Some collectors say they started or stopped making collections at important point: the beginning or end of adolescence—“it's a growing-up thing; you stop when you grow up,”says one. Other painful times are mentioned, such as the end of a relationship. For time and life can seem so uncontrollable that a steady serial（顺序排列的）arrangement is comforting.

Preparing Cities for Robot Cars

    The possibility of self-driving robot cars has often seemed like a futurist's dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

    While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

    Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services.

    A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

    Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn't extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

    Messages in honor of Stan Lee are pouring in on social media and other online sites.

    Lee is the creator of famous comic book characters, including Spider-Man, the Hulk, Black Panther and others. He died in Los Angeles, California, Monday. He was 95 years old.

    Marvel Entertainment and its parent company, Walt Disney, posted a video about the late writer, editor and publisher on their websites.

    Disney chairman and chief Bob Iger said Lee is "a super hero in his own right to Marvel fans around the world." He compared Lee to his comic book characters with "the power to inspire, to entertain, and to connect."

    Lee was born Stanley Martin Leiber in New York City. He began writing for comic books at 19. He wrote under the name Stan Lee. He explained that he used a false name because he wanted to write a serious and great piece of literature someday. He did not want his link with comic books to be known when that happened. But it never did happen. As the pride in his work grew, he decided to legally change his name to Stan Lee.

    Lee's comic book heroes stand apart from its competitor DC, the company that produced the seemingly perfect heroes like Superman and Wonder Woman. Lee's character often had super power, but they also had weaknesses and moral failings. In a piece for Marvel in 1969, Lee discussed the importance of creating these balanced characters. Nobody is all good, or all bad, he wrote, like Tony Stark, also known as Iron Man. He is a deeply gifted inventor with serious mental health issues; or, Peter Parker, a sensitive, brainy high-school student who has no idea how to deal with the frightening abilities he gets from the bite of a radioactive spider. Even Steve Rogers, whose Captain America was the most Superman-like of the Marvel group, had problems. Rejected as a candidate for the armed forces, he volunteers to take a "supersoldier" substance to make him a super-fighting machine.

    Actor Chris Evans has played that character in several Hollywood films. He posted a tribute to Captain America's creator on Twitter Monday. “There will never be another Stan Lee,” he wrote. Actor, writer and funny man Seth Rogen never played one of Lee's characters but he remembered him with thanks in a tweet. “Thank you Stan Lee for making people who feel different realize they are special,” he wrote.

    While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭气) too.

    Vulture (秃鸳)

    Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face.

    Opossum (负鼠)

    In some ways opossums have it easy. In order to become "dead", they don't have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won't move any more than a human statue until the threat has passed.

    Hoatzin (磨雉)

    Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the "stink bird

    Millipedes (千足虫)

    Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.

    Sea Hare (海兔)

    The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.

    Researchers using lobsters (2-f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is.

    Now, more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the long-hours work culture to make more money to buy more things is eating up their lives, leaving them very little time or energy for family or pastimes. Many are turning to other ways of living and downshifting is one of them.

    Six percent of workers in Britain took the decision to downshift last year. One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs, leaving their two children with a nanny(保姆). Most evenings Daniel wouldn't get home until eight or nine o'clock, and nearly twice a month he would have to fly to New York for meetings

    They both earned a large amount of money but began to feel that life was passing them by.

    Nowadays, they run a farm in the mountains of Wales, I always wanted to have a farm here, says Daniel, "and we took almost a year to make the decision to downshift. It's taken some getting used to, but it's been worth it. We have to think twice now about spending money in car repairs and we no longer have any holidays. However, I think it's made us stronger as a family, and the children are a lot happier."

    Liz, however, is not quite sure. "I used to enjoy my job, even though it was hard work and long hours. I'm not really a country girl, but I suppose I'm gradually getting used to looking after the animals. One thing I do like, though, is being able to see more of my children. My advice for other people wanting to do the same is not to think about it too much or you might not do it at all."

    "I will need to open your neck to remove the tumor," the surgeon told me on a hot summer day. The words turned into white noise. "So, an ugly scar across my neck, then?" I asked. The nurse said: "Don't worry. The closure is like his signature. Just like you want a perfect scar, he wants to give you one. You'll barely see it." I found some comfort in that.

    I googled "cancer surgery scar" and was presented with neck images: necks with red and purple lines, closed with stitches or glue; necks with multiple scars....It was enough to make me shut my Macbook, as anxiety pulsed through my body. In the mirror, I admired my neck, running my finger across a gold chain I wore. Then a tiny voice said:" Mummy!"

    My then fie-year-old son. Jack, appeared in the mirror behind me. Our reflection was a big reality check. See, my son didn't know I had cancer and was having surgery. I'm a single mom. Jack lives with me and doesn't have a relationship with his father. I'm his hero. I'm the homework helper, nurse, chef, taxi driver, and every other variation of parent. I knew I couldn't lose heart over cancer or some scar on my neck --I'm this kid's life!

    So I did the next best thing I could think of: I made an appointment to get my hair done a few days before the first surgery. My goal was simple: golden hair to frame my scar. If I couldn't hide it, I might as well show it off. I never had any intentions of hiding the scar. I didn't want my son to think my scar was something to be ashamed of. I'm his role model and I needed to set a good example. Bad things can happen, but it's how you deal with them that matters.

    The scar proves I faced my fear and won. If I got through that I can get through all the hardships, land on my feet and live boldly.
