Mobile phone must be switched off inside the State Apartments and St George's Chapel in consideration of other visitors.

    Security

    As Windsor Castle is a working royal palace, visitors and their belongings should get through airport-style security checks. For safety and security reasons a one-way system operates along the visitor route.

    Birds' feathers are some of the most strikingly variable animal characteristics that can be observed by the eyes. The patterns that we see in birds' feathers are made up of combinations of scales, bars, and spots.

    We already know why birds have colored feathers. Generally, the color of feathers may protect a bird from being noticed by the enemy in the environment, or it can make a bird more appealing to potential mates by helping them to stand out. These aspects are well known. A greater mystery has been how the patterns are created.

    Dr. Ismael Galván and his team studied the color of feathers to see what types of colors were present in birds' complex feather patterns. The study shows they mainly consist of two types of colors: melanin（黑色素）, which produce a range of black, grey, brown, and orange color, and carotenoids（类胡萝卜色素）, which are used to create brighter colors.

    Birds cannot produce carotenoids on their own. For feathers with bright colors, birds must consume food items that contain these paints, and the carotenoids circulate through the blood and to the feather. Melanin, on the other hand, is produced by special cells in the birds' bodies.

    The team found that about 32% if the species studied have complex color patterns, with the vast majority of these complex patterns produced by melanin rather than carotenoids. If the birds were artists, they would use carotenoids as a broad brush to produce color patches, with melanin as a detail paint brush to produce more complex designs.

    But a few birds are exceptions to this rule: Three bird families do have complex patterns without melanin.

    This activity will melt away the pounds, build your body and leave you on an emotional high. Yet the form of exercise, the fitness trend of the year, does not require gym membership or a personal trainer. All you need to do is walk.

    “Walking is a refreshing alternative to complicated aerobic ( 氧) routines and overpriced gym membership,” says personal trainer Lucy Knight, author of a new book on the exercise. “It is free, enjoyable and already a part of everyday life. All you need to do is correct your technique, walk faster and for longer and you will lose weight.”

    There is much evidence of the benefits of walking. Scientists at the University of Pittsburgh recently discovered that overweight people who walked briskly ( 快) for 30 to 60 minutes a day lost weight even if they didn't change any other lifestyle habits. Another American study found that people who walked for at least four hours a week gained less weight than couch potatoes as they got older. Researchers at the University of Massachusetts medical school found that people who walked every day had 25 percent fewer colds than those who sat a lot. Best of all, walking makes you feel good about yourself. “For people suffering from depression, walking three to four times a week for 30 minutes has been shown to lift their mood,” says Knight.

    But how to walk your way to weight loss and wellness? Health experts recommend that we should walk 10,000 steps a day to stay healthy. Actually you would probably need to walk at least 16,000 steps a day to lose weight. “Your workout plans depend on your level of fitness. You should aim to progress by increasing your walking time by five minutes every two weeks, and walk a bit faster. In just three months, the results should speak for themselves,” says Knight.

    Podcasts (播客)

    The B S. Report

    Designed for the sports fan with a sense of humor, the B.S. Report is hosted by the sportswriter Bill Simmons. Simmons show is in very loose and free form and it's not uncommon for him to go almost a whole show without even mentioning sports.

    Wait, Wait…… Don't Tell Me

    One of the most popular Programs on National Public Radio, Wait. Wait... Don't Tell Me is now available as a podcast. The show is a news program in the form of a game show. Each week a group of humorists and writers join host Peter Sagal in Chicago, where they are quizzed on the weeks most important and funny news stories. Listeners also get to call in to play different news-related games for a prize

    The Moth

    The Moth is a weekly podcast run by a nonprofit art organization. The show is made up of recordings of “true stories told before a live audience without notes”. Each week, the group releases short 10-20 minute tales told by people from all walks of life. Past Presenters have included writers, comedians, scientists, and even New York City police officers.

    Film spotting

    Film spotting is a weekly podcast and is a must-listen for any movie fan. The show is focused on movie reviews, but hosts Adam Kempenaar and Matty Robinson do more than just tell their listeners which new movie is worth seeing. They also discuss and examine the film as an art form. The how doesn't just focus on current movies, either, as the hosts frequently discuss old films as part of theme marathons.

With the completion of the Human Genome（基因组）Project more than 20 years ago, and the discovery of the double helix structure of DNA enjoying its 70th birthday last year, you might assume that we know how life works. Think again!

Evolution has a 4bn-year head start on us. However, several aspects of the standard picture of how life works-the idea of the genome as a blueprint, of genes as instructions for building an organism, of proteins as precisely tailored molecular（分子）machines and more-have wildly reduced the complexity of life. 

In the excellent book How Life Works, Philip Ball explorers the new biology, revealing life to be a far richer, more delicate affair than we have understood. Ball explains that life is a system of many levels-genes, proteins, cells, tissues, and body modules-each with its own rules and principles, so there is no unique place to look for an answer to it. 

Also, How Life Works is a much more appealing title than the overused question of "What is life?". We should be less concerned with what a thing is, and rather more focused on what a thing does. Defining a living thing implies an unchangeable ideal type, but this will run counter to the Darwinian principle that living things are four-dimensional, ever changing in time as well as space.

But it's an idea that is deeply rooted within our culture. Ball points out that we rely on metaphors（比喻）to explain and explore the complexities of life, but none suffice. We are taught that cells are machines, though no machine we have invented behaves like the simplest cell; that DNA is a code or a blueprint, though it is neither; that the brain is a computer, though no computer behaves like a brain at all.

Ball is a terrific writer, pumping out books on incredibly diverse subjects. There's a wealth of well-researched information in here, and some details that are a bit chewy for the lay reader. But the book serves as an essential introduction on our never-ending quest to understand life.

→After the three new projects {#blank#}1{#/blank#}, I am sure I can apply my experience to this job.
