Cows always rest on their chests so that their digestion is not impaired. Rodents sometimes rest sitting down, while kangaroos sometimes lie on their backs. The larger the animal, the less often it lies down, and when it ...

Designer organelles bring new functionalities into cells

For the first time, scientists have engineered the complex biological process of translation into a designer organelle in a living mammalian cell. Research by the Lemke group at the European Molecular Biology Laboratory (EMBL) ...

Pressure makes best cooling

Phase transitions take place as heat (i.e., entropy) is exchanged between materials and the environment. When such processes are driven by pressure, the induced cooling effect is called the barocaloric effect, which is a ...

A fascinating phase transition from one liquid state to another

A team at the University of Tokyo has described in unprecedented detail the rare phenomenon of liquid-to-liquid phase transitions in a pure substance. By showing how a liquid made of just one type of molecule can switch between ...

Color-changing sparks

Sparks are a fascinating phenomenon well-known from campfires, flint stones and electric sparklers and other pyrotechnic articles. Looking at sparks more closely reveals the limited colors in which they appear. Dark red-orange ...
