High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

Even embryos can become embroiled in an evolutionary arms race with another species. Leiden biologists demonstrate this with larvae of the rosy bitterling that parasitize the gills of freshwater mussels. They published their research on February 19 in PNAS.

Leiden archaeologists have identified a number of bone fragments that were excavated in Germany two years ago. The fragments are from a sabre-toothed cat and appear to be parts of the skull of a prehistoric feline that is over 300,000 years old.
