A closer look at antibiotic resistant genes in the air

While the issue of antibiotic resistance genes (ARGs) in water has long been studied, relatively little attention has been paid to airborne ARGs, despite its potential to pose a significant threat to public health. A team ...

The hidden hazards of antibiotic resistance genes in air

People are often notified about poor air quality by weather apps, and this happens frequently in urban areas, where levels of outdoor pollution containing particulates and soot are high. But now scientists are reporting in ...

Small birds have more efficient wing strokes than bats

Small birds are more energy-efficient than bats when flying. Researchers previously believed this was due to air resistance created by the bats' ears. However, biologists at Lund University in Sweden have now discovered another ...

Getting quicker – more quickly

A new procedure simplifies wind tunnel tests and makes the results visible immediately. Athletes have gone up against the wind at ETH to test the new method.

New study changes view on flying insects

For the first time, researchers are able to prove that there is an optimal speed for certain insects when they fly. At this speed, they are the most efficient and consume the least amount of energy. Corresponding phenomena ...
