A dry surface thanks to fluid physics: Contact-free method gently remove liquids from delicate microstructures
Researchers at the University of Konstanz have developed a gentle, contact-free method to collect liquids and remove them from microscopic surface structures. The method uses vapor condensation to generate surface currents that transport droplets off surfaces.
Sparse tongue hair explains why queen bees stop foraging when workers emerge
During spring, when queen bumblebees first emerge from hibernation to start their nests, they work incredibly hard foraging for nectar to fuel their new colonies. But then, as soon as their first workers are born, they seem to slack off.
Microbial genes could improve our understanding of water pollution
Underground environments like soil and aquifers teem with microbial life. These tiny microbes play a big role in cycling nutrients and breaking down or transforming pollutants. However, scientists still struggle to reliably model how microbes grow and decay.
A tiny mouse hints at why some mammal mothers may benefit from choosing more than one father
Many animals do something that still surprises researchers: females often mate with more than one male. This behavior—polyandry—has long raised a blunt question. Why divide offspring among multiple fathers, and does it help mothers or young survive?
Melting glaciers may mix up waters more than we thought
As marine-terminating glaciers melt, the resulting freshwater is released at the seafloor, which mixes with salty seawater and influences circulation patterns. As the oceans warm, it's growing increasingly important to study this process.
