Scientists Working To Save Arctic Ice Cap

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.

NASA Discovery: 7 Earth-Sized Planets

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 Will Turn Trash Into Tools

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.

Hurricane Matthew Downgraded To Category 1

Hurricane Matthew has been downgraded to a Category 1 Hurricane, according to The Weather Channel’s website.

That means that weather experts believe that much of its destructive power is lessening.

That’s good news for more than a million people in Florida, Georgia and North and South Carolina, who were forced to flee the storm.
