One fact about our time is becoming increasingly well-known. No matter how far you travel, no matter in which direction you point, there is nowhere on Earth that remains free from the traces of human activity.

Rainforests are the oldest living ecosystems and without a shadow of a doubt, the most vital habitats on Earth (Amazon rainforest has been in existence for at least 55 million years). The Amazon represents over half of the planet’s remaining rainforests, and comprises […]
Sleep. We all need it, and most of us don’t get enough of it. And even if we get the average recommended amount (the good old 8-hour dosage), that takes up about a third of our lives overall. But why do we sleep, from an evolutionary standpoint? The fact that it’s so widespread in the […]
Philip Donkersley, Lancaster University How important are bees and what will happen when they go extinct? Is there research into what is killing them?
