Every bunny counts

Many cocoa farmers live in poverty – yet the fairly traded chocolate bunny often stays on the shelves. We should pay more attention to origin when buying chocolate, believes Isabel Günther.

Addressing plastic pollution

Microplastic pollution is a serious problem, but blanket bans won’t solve the issue, says Denise Mitrano. We should regulate plastics more precisely to create incentives for both innovation and environmental safety.

Climate-friendly, but antisocial

Making agriculture climate-neutral has a high cost – which some rich countries might be willing to accept, ETH Zurich researchers find.

ETH Zurich and University of California Santa Barbara researchers reveal the extent to which rivers across the USA are losing flow to aquifers.

Voltage from wood

Researchers at ETH Zurich and Empa have chemically modified wood and made it more compressible, turning it into a mini-generator. When compressed, it generates an electrical voltage. Such wood could serve as a biosensor or as a building material that harvests energy.

Climate change influences river flow

River flow has changed significantly worldwide in recent decades. An international research team led by ETH Zurich has now demonstrated that it is climate change, rather than water and land management, that plays a crucial role at a global level.
