New computer simulations, paleomagnetism and plate motion histories reveal how hotspots, centers of erupting magma that sit atop columns of hot mantle that were once thought to remain firmly fixed in place, in fact move beneath Earth’s crust.
During the recent years yeasts have been causing more and more infections in humans. One of them can mutate surprisingly quickly by reorganizing its chromosomes. This enables this yeast to tolerate higher doses of anti-fungal medicine.

How do single celled bacteria living as part of a complex community called a biofilm “decide” between different physiological processes, such as movement or producing the “glue” that forms the biofilm? A leading expert explains it is important to understand how biofilms form as they are often the basis of chronic infections and also of [...]

The visual system has limited capacity, and cannot process everything that falls onto the retina. Instead, the brain relies on attention to bring salient details into focus and filter out background clutter. Two recent studies have helped to unravel the mechanisms underlying attention.
