Mining can have serious consequences for nature and the health of the population in countries of the Global South, where environmental laws are often only inconsistently implemented. In Hwange, in western Zimbabwe, people have been fighting water pollution from coal mining for years. But they were powerless against the operators – until doctoral student Désirée Ruppen launched a citizen science project in 2018.

Researchers from the Paul Scherrer Institute PSI, in a project led by scientists from the University of Sheffield, have developed a new simulation of the most dangerous radioactive debris from the Fukushima nuclear power plant. Their study could give an enormous boost to the cleanup effort. They are publishing their results today in Nature Materials Degradation.

Whether on top of a cappuccino or in the wake of waterfalls, foam is omnipresent. Until now, simulating foams realistically with a supercomputer has been almost impossible, but a method further developed by the research group of ETH and Harvard professor Petros Koumoutsakos has overcome the hurdles.

Scientists from 48 countries initiated the “European Reference Genome Atlas” at the start of 2021. Within this project, around 600 researchers aim to decode the genetic repertoire of all species of the continent by generating reference genomes for the roughly 200,000 eukaryotic species. The hope is to strengthen the foundations for conservation of biodiversity.

Hydropower delivers renewable electricity, but comes with massive fish mortality – a global dilemma that can only be addressed by true compromises, says Luiz Silva, and outlines how to find them.
