Humans have been transforming seawater into potable freshwater for millennia. Today, billions of people can’t access clean drinking water, and 87 different countries are projected to be “water-scarce” by 2050. So, how can we use seawater...

Throughout history humans have come up with lots of different ways to build shelters for themselves. But sometimes, inspiration for better construction materials comes from nature, in structures you might not expect — like the scales on a

Migrating birds care more about the ease of their trip than the distance they travel, and that leads to some truly roundabout routes.

The law of conservation of energy tells us that energy is neither created or destroyed - just converted from one form to another. This means that we cannot make energy from nothing and energy does not just disappear. Energy, however, can...

We put aerogel to the test vs 'not-a-flamethrower', a huge 2000°C flame to a large fiberglass blanket infused with silica aerogel - formerly the lightest solid (that title is now held by graphene aerogel).

Hawking radiation was first discovered by English scientist Stephen Hawking in 1974. Prior to this discovery, our knowledge of black holes was very limited. It was believed that black holes were completely black and that they did not...
