    Oh, the places you'll go!

    When it comes to habitat, human beings are creatures of habit. It has been known for a long time that, whether his habitat is a village, a city or, for real globe-trotters (周游世界者), the planet itself, an individual person generally visits the same places regularly. The details, though, have been surprisingly obscure. Now, thanks to an analysis of data collected from 40,000 smartphone users around the world, a new property of humanity's locomotive (移动的) habits has been revealed.

    It turns out that someone's "location capacity", the number of places which he or she visits regularly, remains constant over periods of months and years. What constitutes a "place" depends on what distance between two places makes them separate. But analyzing movement patterns helps illuminate the distinction and the researchers found that the average location capacity was 25. If a new location does make its way into the set of places an individual tends to visit, an old one drops out in response. People do not, in other words, gather places like collector cards. Rather, they cycle through them. Their geographical behavior is limited and predictable, not fancy-free.

    The study demonstrating this, just published in Nature Human Behavior, does not offer any explanation for the limited location capacity it measures. But a statistical analysis carried out by the authors shows that it cannot be explained solely by constraints on time. Some other factor is at work. One of the researchers draws an analogy. He suggests that people's cognitive capacity limits the number of places they can visit routinely, just as it limits the number of other people an individual can routinely socialize with. That socialization figure, about 150 for most people, is known as the Dunbar number, after its discoverer, Robin Dunbar.

    Lehmann says his group is now in search of similar data from other primates (灵长目动物), in an attempt to work out where human patterns of mobility have their roots. For those, though, they will have to rely on old-fashioned methods of zoological observation unless they can work out a way to get chimpanzees to carry smartphones.

    A Swiss airplane powered only by energy from the sun left from Abu Dhabi early on March 9. Its creators hope the plane will make the first around-the-world journey without any fuel. The plane is called Solar Impulse 2. It has one seat and is made from carbon fiber. The plane weighs only as much as a car but its wings are wider than a Boeing 747. The plane's wings stretch 72 meters across. Those wings include 17,000 solar units, or cells, which capture the sun's energy. The energy allows the plane to fly day and night.

    Two Swiss scientists built the plane. Bertrand Piccard is also an explorer who made the first non-stop flight around the world in a balloon. Andre Borschberg is an engineer and trained fighter pilot. The scientists say they are not trying to alter the airplane industry. Instead, they want to show that new energy sources and technologies can achieve what some say is impossible. “We want to show we can fly day and night in an aircraft without a drop of fuel.” Mr. Piccard said.

    Some parts of the trip will require the pilots to be in the tiny plane for five to six days and nights in a row. So it is good that the pilot's seat is also a toilet.

    The plane's route begins in the United Arab Emirates. The pilots also plan stops in Oman, India, and China. They will cross the Pacific Ocean, stop in the United States, and continue over southern Europe or North Africa. They plan to arrive back in the United Arab Emirates in late July or early August.

    Internet viewers can go to the Solar Impulse website to see the plane's location and listen to broadcasts from the pilots.

    One spring day, once the flowers have begun to open, a bee will hover (盘旋) and zip through your yard and dive-bomb your picnic table. While you're thinking about avoiding an attack, that bee is focused on something else entirely: me.

    A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, straw-like tongue into a hundred or so flowers. When the bee has had her fill, shell fly home. There the bee will deposit what she has got into the mouth of one of her co-workers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the comb. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4, 000 flowers, and yet will produce only one-twelfth of a tea spoon of me.

    The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally—I never go bad.

    Alas, my good health is not guaranteed. The problem lies in the growth of industrial agriculture and the use of pest control chemicals, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit I'd appreciate your letting your own garden grow just a little wild My future depends on all of us fostering spring and summers wild flowers, thus helping the bees, who give so much—to you, to me—without ever asking for anything in return.

Europe is famous for big cities and world-class art museums. It's easy not to notice the small, beautiful villages in Europe. However, if you're after relaxation, peaceful country walks, beautiful buildings, and chances for different cultures on your next trip, consider cutting down some of your city time and head out to a village instead. Here are three of the most beautiful villages in Europe, along with our top picks for places to stay in each.

Bibury in Gloucestershire, England

Often praised as the most beautiful village of the Cotsworlds, Bibury is also one of the most popular places for visitors to stay in the area, and attracts a lot of tourists from around the world. It's set among the green hills that the area is known for and is composed of light-beige(浅米色) stone houses, including the famous Arlington Row, a line of houses dating back to 1380.

Cong in County Mayo, Ireland

Set on a small sea-facing island on the western coast of Ireland, Cong is a quiet village that's famous for its grey stone ruins and many outdoor activities. One of the biggest reasons for its fame is that the 1952 film The Quiet Man was made there, but the biggest draw for most visitors is the chance to visit (or stay in) Ashford Castle, which is now run as a great expensive hotel.

Montepulciano in Tuscany, Italy

Spread over a hilltop nearly 2, 000 meters above sea level, the Tuscan village of Montepulciano offers beautiful buildings from the Middle Ages, as well as many chances to visit wineries(酿酒厂) and taste the locally produced Vino Nobel di Montepulciano. With fortifications(防御工事) dating back to the 14th century, the village has churches and public squares, which are truly fascinating.
