Eating Healthy Can Lead To Better Grades: Studies

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.

How Much Food Do You Waste?

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.

“Adventure” Playgrounds Can Build Confidence

“Adventure” Playgrounds Can Build Confidence

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.

The Truth About Tech

Some of the people who created many popular apps are telling kids to put their phones away–at least, a bit more often.
The Center for Humane Technology is made up of people who used to work for big tech companies like Google, Facebook and Twitter. Now they want kids to stop using those apps and websites so much.
In early February the Center, along with Common Sense Media, launched an awareness campaign called the Truth About Tech. Its goal is to teach students, parents and teachers about the dangers of spending too much time on smart phones and tablets.

Cave On The Moon Could Be Base For Astronauts

Cave On The Moon Could Be Base For Astronauts

Scientists from JAXA, the Japanese space agency, say they have discovered an enormous underground cave on the moon.

The discovery is exciting because the cave could provide a safe place for astronauts to live and work on future missions to the moon.

In 2009, a lunar probe launched by JAXA sent back images of the cave’s entrance. The probe used radar to determine the underground structures below the entrance and sent the information back to JAXA to be analyzed.

In October, JAXA announced that there appears to be a cavern about 50 kilometres (31 miles) long and 100 metres (328 feet) wide leading from the opening.

Scientists say the cave could make an ideal base for astronauts. It would protect the astronauts and their equipment from the extreme heat and cold on the moon’s surface. It would also help keep them safe from micrometeorites (tiny particles of space dust) that land on the moon, and from the harmful rays of the sun.

33% Of Canadians Say They Are Science Illiterate: Survey

Science plays an important part in our everyday lives. But according to a recent survey, one out of three Canadians don’t feel they really understand it.

The Ontario Science Centre posted a “science literacy” survey online last August. People answered questions about how well they understand scientific information, and whether they believe and trust information they get about science from the media.

Most of the people who took the survey consider themselves “science literate.” That means they feel they have a reasonable knowledge of things like how science is done (scientific methods) and recent discoveries in science.

Scientists Identify New Organ

Scientists have identified a new organ in the human body. It’s called the mesentery (pronounced mess’-en-tair-ee). An organ is a group of tissues that has a specific function in the body. Our bodies have 79 organs, including the heart, lungs, brain, skin and stomach. The mesentery is made of fatty tissue and is shaped a bit like a fan. It is attached to the back wall of the abdomen and it helps to support the intestines and hold them in place.

Cassini Spacecraft Begins Last Stage Of 20-Year Mission

In October 1997, a spacecraft called the Cassini orbiter was launched on a mission to explore Saturn and its moons.
Now, after nearly 20 years in space, Cassini’s mission is coming to an end. Cassini is running out of fuel. Scientists expect it to burn up in Saturn’s atmosphere in September.
But before that happens, the spacecraft will make a series of dives between Saturn and its rings, sending photographs and other information back to Earth.
