1 . Eat like a king in the morning, a prince at noon, and a peasant at night. This saying is all about the importance of breakfast. And now scientists can tell us just why it’s so important. According to a study carried out at Imperial College London, UK, skipping the first meal of the day not only means you eat more at lunch, but also that your brain wants to find more unhealthy foods.
The study suggests that there is a special part of our brain called the orbitofrontal cortex, which plays an important part in making choices about what we eat. It is used for identifying the taste of food, especially when skipping breakfast. It is more likely to target high-calorie foods when you’re on an empty stomach.
Scientists did an experiment on this. Dr Tony Goldstone from Imperial College London, scanned the brains of 21 men and women, around the age of 25. On the first day, these people skipped breakfast before the scans. On the second day, they had cereal, bread and jam as breakfast. After the scan on both days, they had their lunch.
When the volunteers had skipped breakfast, they ate around 20 percent more at lunch, compared with days when they had eaten breakfast. Their brain scans also showed the orbitofrontal cortex was especially responsive to high-calorie foods. “We believe that bit identifies the value of foods — how pleasant, how delicious something is,” Goldstone told The Guardian.

2 . Being compared to great people like Stephen Hawking and Albert Einstein is not something that happens to the average person. At the age of just 23, Sabrina Gonzalez Pasterski has already achieved much more goals than most of us ever will in our lifetime.
When she was only 14 years old, the Chicago girl made her own single engine airplane—by herself. She then flew it across Lake Michigan, becoming the youngest person to ever fly their own plane.
She graduated from Illinois Mathematics and Science Academy (IMSA) in 2010 and entered Massachusetts Institute of Technology (MIT).
At first, she had to wait to be accepted into the school, but once Professors Allen Haggerty and Earll Murman watched her video they had no doubt. Femalista quoted Haggerty as saying: After just three years at MIT she has already achieved the highest possible grade point average of 5.0.
She is now studying further at Harvard University, with full academic freedom. Once again she is only 23 years old.
What's even more impressive is that she is no longer interested in building planes but has turned her attention to physics, namely black holes and how gravity (重力)affects space and time —that is why she is being compared to Einstein and Hawking.
Pasterski records all of her work on her website Physics Girl, but if you are a little shocked by her achievements, she has some words for you.
During an interview with Marie Claire earlier this year she said: Being optimistic about what you believe you can do. When you're little, you say a lot of things about what you'll do or be when you're older—I think it's important not to forget those dreams."

3 . One day in March, seven years ago, during happy hours at a bar in my hometown of Fayetteville, Arkansas, I made a surprise announcement to my friends: I was going to shut down my law practice and attempt to travel around the globe in a year. What’s more, I would do it without taking any flights or making a single advance reservation (预定) of any kind. My announcement drew mixed reactions from my friends. Some offered support and encouragement, while others were more doubtful.
Once I had said the words, there was no turning back. I took months to shut down my law practice and get things in order. Once I set off on my adventure in December 2008, I found travelling without using planes was not easy. Trying to circle the globe in 16 months (it took me a bit longer than the initial 12 months I planned) made it even harder. Even so, travelling overland was the most amazing way to truly understand the immensity (浩瀚无际) of our wonderful planet.
I took three consecutive (连续) overnight buses to travel 3,000 km through Argentina, from Ushuaia to the capital Buenos Aires. I would look out of the windows for hours continuously at the completely plains, as if humans had never touched it.
It took seven consecutive days and nights on trains to get from Moscow to Beijing, each day spent staring out of the windows for hours as the Siberian plains swept by. Sometimes, I wouldn’t see a village or a human being for 10 hours. Later in my journey, it took 22 days on a cargo freighter (货船) to get from New Zealand through the Panama Canal and back to Philadelphia, to finish my round-the-world adventure.
It turned out that travelling with no reservations was far less difficult than I had imagined. Pulling into a city on a bus with a backpack, looking in a guidebook for a few suggestions of accommodations (住所), and then finding an empty room was never much of problem anywhere. It also kept me flexible (灵活) and open about all my travel plans, which is advice I give everyone who asks—plan for less than you think you should.

4 . One advantage of the Internet is shopping conveniently online for clothes; one disadvantage of the Internet is also shopping conveniently online for clothes.
“Nothing fits,” said Lam Yuk Wong, a senior in electrical and computer engineering at Rice University. “Everyone says this. They order clothes and they don’t fit. People get very unhappy.”
Wong and her design partner, Xuaner “Cecilia” Zhang, are Team White Mirror, creators of what they call a “virtual (虚拟) fitting room”. Their goal is simple and consumer-friendly: to let online clothing shoppers have a perfect fit and a perfect look when shopping every time.
Both women are from China, Wong from Hong Kong and Zhang from Beijing. They both order most of their clothing online. They got the idea from their own experience as consumers and from listening to the complaints of friends and relatives. “They say, ‘The color is wrong’ or ‘I got the right size but it still does not fit.’ We want to make it like you’re in the store trying on the clothes,” Zhang said.
Using a Kinect developed by Microsoft for use with its Xbox 360 video game player,
Zhang scans Wong and turns her image into, in effect, a virtual model, keeping Wong’s dimensions (尺寸), and even her skin and hair color. “We put the clothes on the shopper’s 3-D body models and show how they look when they are dressed,” Wong said. So far, Wong and Zhang have adapted the software to show dresses and shirts, and they are now working on shorts.
Asked if she thought men as well as women might be interested in using their virtual fitting room, Wong said, “I think their wives will care about this, so it will also be important to men.”
