Tiny computers reveal how wild bats hunt so efficiently

2021.03.04The bats' echolocation is more advanced than previously thought. Bats muffle their screams almost to a whisper when hunting, so echoes from trees and buildings do not drown out echoes from the prey.

ICARUS aims to understand the clouds over the Arctic

2021.02.26The Arctic region is very sensitive to climate change and the ongoing changes in the Arctic are a crucial factor affecting the global climate. Therefore, it is important to understand what determines the Arctic climatic processes. With a grant from the Villum Foundation, the researchers behind the ICARUS project aim to examine how specific microorganisms can affect formation of ice in clouds.

Electric cable bacteria breathe oxygen with unheard efficiency

2021.02.10Ten years ago, researchers at Aarhus University, Denmark, reported the discovery of centimeter-long cable bacteria, that live by conducting an electric current from one end to the other. Now the researchers document that a few cells operate with extremely high oxygen consumption while the rest of the cells process food and grow without oxygen. An outstanding way of life.
