Environmental DNA reveals secret reef inhabitants
Research
ETH Zurich
An international research team use a global sampling of seawater to reveal which tropical reef fish occur where. To identify species and families, they successfully used the residual DNA shed by the animals present in the water. But not all fish can be traced in this way.
Neural network can read tree heights from satellite images
Research
ETH Zurich
Using an artificial neural network, researchers at ETH Zurich have created the first high-resolution global vegetation height map for 2020 from satellite images. This map could provide key information for fighting climate change and species extinction, as well as for sustainable regional development planning.  
Everyone should have to decide
Politics
ETH Zurich
A presumed consent system for organ donation, which is to be put to the vote in Switzerland, would likely increase the organ donation rate, writes bioethicist Agata Ferretti. In her view, however, there is an even better solution: the obligation to decide.
Light amplification accelerates chemical reactions in aerosols
Research
ETH Zurich
Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models.
Virtual world, real threats
TechTransfer
ETH Zurich
Digitalisation offers a wealth of new opportunities – and criminals and hostile states are only too happy to exploit them. Protecting against such attacks requires a broad range of measures.
Better control of development aid through AI
Research
ETH Zurich
A research team from ETH Zurich and LMU Munich is using artificial intelligence to analyse 3.2 million development aid projects worldwide. Their research reveals trends and funding gaps.
