New technique for sorting micro-particles uses sound waves

Thanks to the rapid progress in tiny tech, we've been mainly using microfluidics to sort tiny particles by size. But now, there's a new way to sort them by shape, which could be a big deal for medical tests and chemistry. A recent study introduces a new method using sound waves to separate oddly shaped particles from round ones without needing any labels. This breakthrough could lead to better...

Study shows cloud clustering causes more extreme rain

Understanding cloud patterns in our changing climate is essential to making accurate predictions about their impact on society and nature. Scientists at the Institute of Science and Technology Austria (ISTA) and the Max-Planck-Institute for Meteorology published a study in the journal Science Advances that uses a high-resolution global climate model to understand how the clustering of clouds and...

New species of fungi potentially harmful to humans identified in freshwater ecosystems

A study by the Mycology and Environmental Microbiology Unit of the Universitat Rovira i Virgili has identified new species of fungi that may cause infections or diseases in people and animals. Carried out in river ecosystems, the research is part of a project on biodiversity and the role played by a large group of fungi, the ascomycetes, in the aquatic ecosystem.
