In a large-scale fundraising campaign, popular YouTubers like Mister Beast and Mark Rober are currently trying to rid the oceans of almost 14,000 tonnes of plastic waste. That's about 0.15 per cent of the amount that ends up in the oceans every year. But it's not just our waters that are full of plastic. A new study shows that the spread of nanoplastic through the air is a more widespread problem than previously thought.

Chimpanzees don-t automatically know what to do when they come across nuts and stones. Researchers at the University of Zurich have now used field experiments to show that chimpanzees thus do not simply invent nut cracking with tools, but need to learn such complex cultural behaviors from others. Their culture is therefore more similar to human culture than often assumed.

A team of scientists from EPFL and Switzerland's WSL research institute has studied the conversion of savannas into oil palm plantations as a deforestation-free way of growing these plantations. What's more, if improved management practices are adopted at the plantation scale, then the net carbon balance could be enhanced and a great leap could be made towards reducing the environmental impact of palm oil.

Scientists at EPFL have boosted the efficiency and scalability of perovskite solar cells by replacing their electron-transport layers with a thin layer of quantum dots.
