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.
NASA recently released new pictures of Jupiter, the largest planet in our solar system. The photos were taken by the Juno spacecraft. Many of the black-and-white images, sent back to Earth by Juno, have been colourized by people to better show the clouds swirling around the planet. The Juno spacecraft was launched in 2011. Its mission was “to examine Jupiter’s chemistry, atmosphere, interior structure and magnetosophere,” according to a NASA website. Juno arrived at Jupiter in 2016, looking for “clues to its origin and evolution.” Since that time, it has been orbiting (flying around) Jupiter, taking pictures and sending them digitally back to Earth.
When we think of scientific geniuses, we may think of Albert Einstein, Marie Curie or Ada Lovelace. Stephen Hawking was right up there with the most brilliant minds of any generation. He passed away last week, at the age of 76.
It would take a book — or a movie (there are both) — to even scratch the surface of his accomplishments, his tremendous sense of humour, his influence on millions of people and the vast depths of his knowledge.
He helped the world better understand black holes and string theory. Black holes are extremely dense regions in space. We can’t see them. In fact, we can understand what they are only by how they affect things around them. Hawking furthered our understanding of them and many other areas of physics. His groundbreaking work changed science forever.
The Cassini space probe’s 20-year mission to Saturn is over. On September 15, at 4:55 a.m. Eastern Time on Earth, the spacecraft entered the atmosphere around Saturn. Moments later, it was destroyed. Cassini was launched in 1997. It had been […]
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.
Getting paid to stay in bed all day sounds pretty good. But what if someone offered you $23,000 to stay in bed for two months? That’s the deal that a medical research team in Toulouse, France, is offering to 24 volunteers.
Researchers at MEDES, the Institute of Space Medicine and Physiology, are looking for volunteers to help them study the effects of weightlessness on the human body by spending 60 days lying down. Lying in bed isn’t exactly the same as being weightless, but the effects on the human body are similar.
Students at public schools in Boston, Massachusetts, will soon be looking at the world in a new way. Social studies teachers there will be using a new type of map that shows the world’s continents in slightly different sizes and positions than we usually see them.
A team of scientists has come up with a plan they say could help rebuild the Arctic ice cap. The ice cap is a huge area of sea ice that covers most of the Arctic Ocean all year round.
Usually, the sea ice gets thicker and spreads further each winter, but this hasn’t happened for the past few years.
Last month, the ice cap had shrunk to its smallest size since scientists began keeping records of it 38 years ago. The weather in the Arctic has been unusually warm this winter. Some days, temperatures have been 20 degrees Celsius higher than is normal for this time of year. This month, the temperature was above 0°C at least one day.
Scientists from NASA announced on February 22 that they have discovered seven planets orbiting a nearby star. The planets are all about the same size as Earth, and three of them are in what scientists call the “habitable zone.”
(The habitable zone is the area of space around a star where a planet is most likely to have liquid water on its surface. Scientists believe water is necessary for anything to live on a planet.)
Astronauts on the International Space Station (ISS) may soon be able to turn their used forks and knives into tools and satellite parts.
Tethers Unlimited Inc., an aerospace technology company, has developed a system that combines a waste recycling machine with a 3D printer.
Astronauts will put waste items made of plastic into the recycling machine, called the Positrusion Recycler. When they press a button, the Recycler will sterilize and melt down the plastic and turn it into 3D filament.
