People have used pigeons to carry messages to one another for hundreds of years. In fact, pigeons were a common way to send messages right up through Would War II.

    In 1815, English troops were fighting Napoleon's forces in France, and the English were believed to be losing. A financial panic swept over London. Government bonds（债券）were offered at low prices. Few people noticed that Nathan Rothschild, an English banker, was snapping up these bonds when everyone else was trying to sell them. A few days later, London learned the truth: the Duke of Wellington had defeated Napoleon at the battle of Waterloo. The value of the bonds soared（暴涨）, and Rothschild became wealthy…all because his pigeons had brought him news of the victory before anyone else knew of it.

    Carrier pigeons were used by countries in both World War I and World War II. Not only were the birds often the fastest, most reliable way to send messages, they could also be used to reach soldiers far behind enemy lines, where radios and field telephone lines were useless. Since they could easily be released from airplanes or ships, every branch of the armed services used the birds.

    Carrying messages could be a dangerous job. Some pigeons performed with such bravery that they became famous and were even awarded medals. The most famous pigeon of all may have been Cher Ami. Stationed in France during World War I, he carried twelve important messages for American forces. On his last mission, though wounded, he carried a message that saved the lives of 194 American soldiers. For his amazing service, he was awarded the French “Croix de Guerre.”

    Today, modern communication methods can carry information from one place to another hundreds of times faster than a pigeon could do it. However, few people would argue with the fact that carrier pigeons — especially those that served in the military — have earned their place in history.

    Most foodies (吃货) agree that eating healthy food is important. But sometimes making good food choices can be tough. Now, there are apps that can help people learn about the food they eat to improve their diets and their dining out experiences.

It provides information about hundreds of different cheeses and advises wines to pair with each. Max McCalman's Cheese & Wine Pairing app is free for iPhones and iPads.

Calorific app

    What does 200 calories look like? It can be hard to picture. Calorific provides images of 200 calories worth of food. The pictures can help people on a diet and those who just want to eat healthier food. The app is free for iPads and iPhones. There is also a version that provides more information for a price.

    HappyCow app

    Vegetarians do not eat animal meat. Vegans do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world. A free version of HappyCow is available for Android that has ads and requires an Internet connection.

    If you could sail around the world with only one companion, who would you choose? Guirec Soudee, a 24-year-old man from France, chose his pet chicken.

    Soudee has been sailing around the world for two years. No matter which country he sails to, Monique, the hen, is by his side. He found her in the Canary Islands and knew right away they were meant to be best companions. "I didn't speak any Spanish and she didn't speak any French, however, we could always have a small talk, even though she didn't understand me." Soudee joked.

    He had always wanted a companion for his journey and originally thought about bringing a cat, before deciding it would be too much work to look after on a boat. Upon meeting Monique, Soudee realized a hen was the perfect choice. He believed they could communicate with each other well.

    Not only does it cost little to raise Monique, but she lays eggs as well — some things that are always a plus in a situation where storing a lot of food can be a challenge. She lays about six eggs a week on average, even in cold climates like Greenland, where Soudee and Monique are docked(进港) now.

    And what happens when the weather at sea gets bad? Usually Soudee lets Monique stay freely on the boat, but when the winds get terrible he ensures she is safe in her hutch so that she doesn't fall out of his boat and into the sea. Another thing Soudee must care for is the rule in every country he visits. They had met with customs officials in Canada. He was permitted to keep her, but he knows they might not always be so lucky.

    Although Monique can sometimes get on his nerves, Soudee says she's much better than a human companion aboard. "She follows me everywhere. All I need to do is shout 'Monique!' and she will come to me, sit on me, listen to my small talk and give me company," he said.

    After visiting Greenland, they'll head down the Bering Strait to Nome, Alaska. From there the destination is undecided, but Soudee will certainly discuss where they should travel to next with Monique.

Dawn Loggins of Lawndale, N. C. is on her way to Harvard, one of the eight world­famous universities in the eastern US. Nobody encouraged her to study or paid for her special classes. This girl created her own future.

The teen was abandoned by her family last summer, when her parents and two sisters moved to Tennessee. She found herself homeless and had to spend the night on friend's sofas.

The school bus driver learned about Dawn's situation and invited Dawn to move in with her family. Soon, Dawn had a job at Burns High School. She worked from 6 a. m. to 7：40 a. m. before the first school bell rang. She swept floors and picked up trash again in the afternoons, before diving into her studies in the evenings.

Dawn's hard work paid off. She finished school with a 3. 9 GPA and scored 2, 110 on the SAT.

"There were times when I felt like it would be easiest if I gave up," the 18­year­old said." But it was never in me to give up, because I realized that I was never going to be successful unless I got an education."

Even before Dawn's family left her, she led a difficult life. Her family was poor and cups of noodles were often the only food. Dawn" studied by candlelight" because her parents couldn't afford to pay the electricity bill(电费).

Dawn has now reconnected with her family. They are proud of her accomplishments(成就)and are attending her high school graduation.

Bullying on campus is increasingly becoming a problem, but the move by the Sherrard School in California, to set equipment inside toilets to catch bullying incidents is getting a lot of attention.

The school has put up a campus alarm system in sensitive places such as toilets that employs voice recognition and sensitive word activation, so that if someone is being bullied, the system can alert members of staff by sending specific signals. The system uses artificial intelligence for voice recognition, but its effectiveness doesn't depend only on these technologies. More important than the technology are the members of the school staff that are arranged to respond quickly and effectively to the warning calls.

Basically, technology serves as a way of reporting instances of bullying to the school authorities. What is truly noteworthy is the authorities' realization that timely intervention is required to stop bullying. In most cases of bullying in schools, educators and the administrators have overlooked early warning signs. And this can, at times, prove fatal. For instance, in a recent tragic case in Indiana, three junior school students plotted and took the life of their 10-year-old classmate. If the school had paid closer attention to the bullying, the tragedy could perhaps have been prevented. 

Returning to the system in California, should it prove effective, relevant government bodies can consider applying similar mechanisms in other schools to hold back bullying on campus. However, it is significant for them to bear in mind that it is human action, not just technology, that can help address this universal issue. Technology can definitely serve as a vital tool, but it is the human element — attentiveness, care, and timely intervention — that ultimately holds the key to creating a safer environment for all students.
