For the emperor penguins living on the sea ice of Antarctica’s Atka Bay, there is a curious companion in their midst.
The bright yellow ECHO robot on wheels attracts little alarm from the birds, who have come to accept it as a harmless oddity. To the scientists remotely controlling the ECHO, however, the robot is a valuable source of information.
I bet your grandparents never imagined they would see the day when they could plug in a car like a lamp. No more smelly gasoline! No more exhaust polluting the atmosphere!
Electric cars are increasing in popularity with many traditional car companies introducing all-electric models.
However, electric cars use 1-2 kg of magnets to power them - and each of these magnets uses special materials. It turns out that getting the required supplies is harder than you think.
Let's find out why.
We live on Planet Earth, but should we call it Planet Water? A view from space shows blue oceans covering more of the planet than land. Water is also found in the air and clouds, in rivers, and deep underground.
Most of us are used to clean water flowing right into our homes. We drink it, shower with it, and use it to flush the toilets. We water our plants with it.
Have you ever wondered where this water comes from? Or where it goes? Or what might happen if we don’t have enough?
Imagine a warm shower: water flows off your shoulders and down the drain. What happens to this water next?
In most homes, it’s piped away to a sewer treatment plant or a septic system, where the water is cleaned and then discharged.
What do you like to do on a rainy day - sit inside and listen to the pitter-patter on the roof or splash outside and feel the cold drops on your face?
We all depend on rain. It fills rivers and lakes, soaks into the ground, sustains our crops, and keeps the land alive and beautiful. In the past, people got their water from rain, wells, or nearby rivers.
When it’s raining, have you ever thought about how much water falls from the sky? Or where it goes once it lands on the ground?
Would you believe it if I told you your shower water once passed through a dinosaur?
Large buildings contain some surprising sources of water. In the past, they were considered a nuisance and dumped out. Now, these waters are gaining value and being reused.
