The Nobel Prize is one of the biggest prizes in the world.
Dr. Strickland will share the prize with Dr. Gérard Mourou of France and Dr. Arthur Ashkin of the United States.
All three scientists won for their work creating tiny (miniature) tools using lasers.
The prize is $1.28 million. It will be divided among the three scientists. Half the money will go to Dr. Ashkin. Dr. Strickland and Dr. Mourou will share the other half.
A teenager’s dream of cleaning up the world’s oceans may soon come true.
Boyan Slat is a high school student who lives in Holland, in Europe. Seven years ago, he was swimming in the ocean. He saw more trash in the water, than fish. So for a school project, he made a plan to clean up the ocean.
In 2013, Slat formed a group called The Ocean Cleanup. It raised money to put Slat’s water clean-up plan in action.
On September 8, Slat’s plan began.
In the ocean between California and Hawaii is a lot of floating garbage. It is known as the Great Pacific Garbage Patch.
Slat’s group will clean it up using a floating tube. The tube will go around the garbage and trap it.
Four scientific studies, released last year, may help children make better choices about the food they eat. In one study, researchers from Ohio State University found that the amount of fast food children eat – things like burgers, fries and soft drinks – can affect how well they do in school. The researchers compared eating habits and test scores for more than 11,000 students across the United States. Grade five students were asked how often they ate fast food, and then they were tested on reading, math and science. The students were tested again in grade eight. The researchers found that students who had reported eating fast food four to seven times a week when they were in grade five performed worse on the grade eight tests than students who rarely ate fast food.
If all the food that’s thrown away in three American cities could be saved, it would provide 68 million meals for people who don’t have enough to eat, according to a recent study.
A team of researchers in the United States spent a week looking through the garbage bags of 1,151 people living in Denver, New York and Nashville. The researchers wanted to know what kind of food was being thrown away, how much there was, and why it was being tossed.
By asking these questions, the researchers hoped to find ways to reduce the amount of food we throw away, and to give some of that food to people who need it.
The researchers found that, in the cities they surveyed, more than a kilogram of edible food per person is wasted each week. (Edible food is food you can eat. It doesn’t include things like apple cores, egg shells, or bones from meat.)
Fruits and vegetables were the most common edible foods found in the trash, followed by food leftover from meals. Eggs, bread and milk were also commonly thrown out.
At a place called The Land, in Wrexham, Wales, the ground is littered with pieces of wood, old tires, packing crates, and shopping carts. It looks like a junkyard, but it isn’t. It’s a playground.
There’s also a fire pit, hammers and saws, and a rope swing across a creek. Some of the equipment can be dangerous, but the people who run the playground believe that letting children take some risks is good for them.
The Land was created by Claire Griffiths, who has two children of her own. She wanted to build a space where children could play the way they wanted and experiment with different things, without a lot of rules.
