Imagine a future in which buildings tower miles over the streets below, tourists take day trips to the edge of our atmosphere, and multiple space stations can be spotted drifting across the night sky. To make this sci-fi vision a reality, we will need to create new kinds of structures that are lightweight but still strong and tough.
In what is being called the biggest attack on the Amazon in fifty years, Brazil has just opened a massive area of the rainforest up to mining.

Other agricultural myths hinder recognizing the potential to restore degraded soils to feed the world using fewer agrochemicals.
Without knowing it, most Americans rely every day on a class of chemicals called per- and polyfluoroalkyl substances, or PFASs. These man-made materials have unique qualities that make them extremely useful. They repel both water and grease, so they are found in food packaging, waterproof fabric, carpets and wall paint.

It’s been orbiting the sixth planet from the sun ever since, sending back data of immense scientific value and images of magnificent beauty.
