Every school kid knows that Earth has a magnetic field – it's what makes compasses align north-south and lets us navigate the oceans. It also protects the atmosphere, and thus life, from the sun's powerful wind.

Chemist obtains a nanocatalyst base from rice husk

A chemist from RUDN has developed a method to obtain high-porosity silicium dioxide, a base for nanocatalysts used in different types of organic reactions, from rice husks. The results of the study were published in ACS Sustainable ...

Sex or food? Decision-making in single-cell organisms

Unicellular diatoms are able to adapt their behavior to different external stimuli based on an evaluation of their own needs. This was discovered by scientists of the Friedrich Schiller University and the Max Planck Institute ...
