Nanomaterials are opening up new possibilities in medicine. But what if such nanomaterials escape into the environment? Empa researchers are currently assessing potential risks.

A chopping robot with an integrated spraying system helps to reduce the use of plant protection products in vegetable production. This was the result of trials in fields with lettuce and pak choi.

In an Empa research project, study participants rated the noise of new types of aircraft as less annoying than the noise of today's aircraft.

A new web tool called “Carculator” determines the ecological footprint of vehicles with different types of propulsion. According to the Paul Scherrer Institute (PSI) in Switzerland, the calculations are intended to serve as a decision-making aid when purchasing a car.

A new artificial intelligence recognises plastic in the sea from satellite images. This could help to systematically remove plastic waste from the oceans using ships.

Cobalt-based catalysts could be used to turn mixed plastic waste into fuel, new plastics and other products.

Biodiversity is declining rapidly. In order to recognise species worthy of protection in time, a research group from Fribourg wants to combine artificial intelligence, image data and citizen science.

The leading shipping associations intend to establish an international fund with a volume of five billion US dollars to drive forward the reduction of CO2 emissions – the German Shipowners’ Association (VDR) announced.

To slow down climate change, a new type of plant in Iceland filters CO2 from the air. This is then mixed with water and injected into basalt. There it petrifies.

ETH Zurich has put an artificial sun into operation. In the room of a new laboratory, the sun shines at the push of a button, just as it does at midday in the Sahara or in January in Berlin.
