Pakistani youth activist Malala Yousafzai was awarded the 2014 Nobel Peace Prize on Friday, October 10th. She is the youngest Nobel winner in history. Malala shares the prize with Kailash Satyarthi, a 60-year-old man from India who has helped lead a movement to end child slavery around the world.

    Malala Yousafzai was born on July 12, 1997 in Mingora, the SwatDistrict of northwest Pakistan to a Sunni Muslim family. When she was just 11 years old, she started blogging about the Taliban take over of her hometown. Taliban members believe young girls should not go to school. Classroom sthrough out the Swat district were closed for several months. Malala spoke publicly about her desire to go back to school. “All I want is an education,”she told one television broad caster.

    When the Pakistani government regained control, Malala was able to return to class. She continued to blog and speak out about girls' right to education. But on October 9, 2012, the Taliban tried to silence her. Agunman boarded her school bus and shot her on the left side of her forehead. Malala survived, and showed great courage and optimism during her long recovery. Then she became a symbol of the struggle for girls' rights all over the world.

    Malala's mission for peace is unstoppable. Nine months after shewas shot, she gave a now-famous speech at the United Nations. “They thought that the bullets would silence us. But they failed,” she said. “And then, outof that silence came thousands of voice. Weakness, fear and hopelessness died. Strength, power and courage were born.”

    You may think that sailing is a difficult sport, but it is really not hard to learn. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.

    First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.

    Let's start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle to the boat. Then it will catch the wind best.

    If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45°angle to the boat. It needs to be out far enough to catch the wind, but it shouldn't flap(摆动). It shouldn't look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.

    Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can't go in a straight line. You must go first in one direction and then in another. This is called tacking. When you're tacking, you must always keep the sail inside the boat.

    Getting more followers is something we usually associate with social media or micro messaging apps. But soon we could all have a new type of follower—a robotic one.

    Dozens of robots and technology fans gathered in Boston, US, earlier this month for the Robot Business conference. The latest developments in the world of robotics were shown to the public, and this time the trend was robots following people.

    Perhaps the most exciting development on show was the ability of drones (无人机) to follow you from the air, acting as your own personal cameraman or photographer. One example is 3-D Robotics' Iris+ drone, developed by a US-based company.

    The drone is fitted with cameras and has a “follow me” function. It connects with your GPS-enabled Android device, like a mobile phone. Then it flies and follows you around, shooting action film of you from above. The software in the drone makes sure that you're always in the center of the frame.

It can keep working for 15 minutes, as long as there aren't too many trees for it to crash into. This could be exciting for anyone who loves action sports or wants to be the star of their own short film.

    But what if you want to be one of those celebrities (名人) who have helpers carrying all their bags and doing all their chores? A robot called Budgee can help.

    Budgee, made by 5 Elements Robotics, is literally a basket on wheels.It is designed to help elderly and disabled people, or simply anyone who doesn't have enough arms for grocery bags, Wired magazine reported.It can carry up to 22.7 kg of items.

    To make Budgee follow them, its owner will have to wear a small device and use an app to set the distance between themselves and the robot.Budgee even sends a text message when it can't keep up with its owner.

     “I want you to look at the robot like he's your buddy, he's your friend. There's a relationship you develop with the robot,” Wendy Roberts, CEO of 5 Elements Robotics, told gigaom.com.

    It might not be quite the same as robotic assistants we've seen in movies such as Disney's Wall-E, where robots cater for our every need, but that idea doesn't seem quite so far-fetched now.

    Dutch beachcomber (海滩拾荒者) Wim Kruiswijk has accumulated a collection of 1,200 messages-in-bottles over the course of nearly 4 decades and has responded to almost all of them,

    68-year-old Kruiswijk says that his unusual hobby began in 1983 when he found three drift bottles (漂流瓶) on his local beach, each containing letters and return addresses. He wrote to all three addresses and was surprised to receive responses from each one. It was this experience that aroused his interest in hunting and collecting messages in bottles, and he hasn't stopped looking for them since.

"I find my messages in bottles on the beach of Zandvoort, where I live, and on the Dutch Islands," Kruiswijk recently told Great Big Story. "Messages in bottles is slow mail. It takes you days, or weeks, or months to find a bottle. "

In the early years, Kruiswijk would find as many as 50 bottles a year, but since 2000 that has slowed to around 20-30 finds, mainly due to beach cleaning efforts. He believes that the rise of the Internet has also played a role in the diminishing number of messages in bottles, telling Dutch newssite PZC, "I used to get a response at half the bottle messages that I answered. Now that's less; many people want 'instant satisfaction'."

    Throwing a message in a bottle out into the sea is a longstanding human tradition dating back to the time of the Greek philosopher Theophrastus, about 310 BC，who used the bottles to study water currents. Scientists still apply the method to this day, as a means to help researchers develop ocean circulation maps, and to crowdsource scientific studies of ocean currents.

    In the past bottles have also been used to send distress messages from sailors in trouble. They also have been used for memorial tributes, or to send loved ones' ashes on a final journey. One of the more common uses though is just to send invitations out to prospective pen pals, a quaint notion in these modern times, but, as Kruiswijk so clearly shows, an effective one.

Workers are returning to their careers, or starting new ones after age 65.

More than ever, work is where many of us get our sense of purpose. That doesn't end at age 65. After being retired for only three months, Sue Ellen King returned to work at the University of Florida Health in Jacksonville, Florida, where she had been a care nurse and nursing educator for 38 years. She is now working part-time in a position created just for her. "It's perfect," she told The New York Times. "I get the satisfaction of having people appreciate what I do." With the average lifespan for those who reach age 64 now getting all the way to 84 years old, those who reach retirement age still have many potential years of work to go.

Job sites connected toward part-timers, temporary positions, and some can also turn up opportunities that may lead to longer-term work. Fred Dodd tried a part-time job after his unemployment as a clerk for large banks at age 63. He'd thought about retiring then. "But part of me just wanted to keep working partly for the money, but more just because I felt I wanted to do more in my career, " he said.

The retired have the advantage of not needing to focus on the earnings potential of whatever jobs they take on, so these older workers are attracted to more meaningful work. And since they are voluntarily putting their skills and experience to good use, they may well have more flexibility than mid-career people. Two-thirds of retirees who'd come back to the work world were doing meaningful work they enjoyed. Legal work and community service were popular choices, as was teaching—all areas in which older workers might have an opportunity to make their own schedules.

Earning more money rarely seems like a bad idea, but it can cause issues for retirees, including effects when they claim Social Security (申请社会保障) benefits early.

Bergl doesn't consider himself the next Thomas Edison, He's just a man loving animals, Africa and adventure, Yet, Bergl might have invented a tool as great as the light bulb (灯泡) ―a tool that uses modern-day technology to solve an almost prehistoric (史前) problem.

The tool is called the SMART. It is designed to be waterproof (防水的) , shockproof and poacher (偷猎者) proof. Bergl worked with worldwide wildlife groups to develop it in 2011. Since then it has been seen in more than 55 countries where poachers have forced the best-known but most endangered animals to nearly die out .

SMART works as a very simple smart phone―it lets the user record what they see, like animal sightings. changes in animals and illegal activities If a park ranger (管理员) sees something that is very important, that information can be sent to the cloud (云) and sent out to the base camp so they can take action and stop the killing 

Bergl and his workmates travel to African wildlife reserves now and then They teach park rangers in some of the most remote countries how to use SMART. "SMART makes collection of information easier It allows us to pay attention to the things that really important. according to what the information is telling an,"Aid Skim Young, manager of the Etosha National park in Namibia, "thanks to SMART, most of Africa's endangered animals seem to be coming back." 

Bergl never plans to make money from his small but great invention. SMART is free and doesn't even have a patents(专利).
