Analysis reveals how a subset of immune cells rally defenses against infection while keeping harmful inflammatory reactions in check. Experiments confirm a central role for plasmacytoid dendritic cells in responding to infection, driving both the inflammatory response pathway and the production of pathogen-destroying cytotoxic T lymphocytes.

A newly discovered enzyme brings scientists one step closer to understanding how plants manufacture a molecule with potent medicinal properties. Plants of the genus Glycyrrhiza are best known as key ingredients in the popular treat licorice, but they also have a valuable place in the medicine cabinet.

Star-shaped brain cells called astrocytes are found to bridge the gap between global brain activity and localized circuits. Global network activity in the brain modulates local neural circuitry via calcium signaling in non-neuronal cells called astrocytes (Fig. 1), according to research led by Hajime Hirase of the RIKEN Brain Science Institute.

Volcanoes on the sea floor can grow and collapse in rapid pulses, reports a study published online this week in Nature Geoscience. Due to their inaccessible nature, little is known about the evolution of submarine volcanoes. This study provides insights into the frequency and rate at which such volcanoes can erupt and grow.

Pulses of warm ocean water that could reach far beneath the Filchner–Ronne Ice Shelf together with a smooth, steep bed beneath the ice sheet may affect the stability of the West Antarctic Ice Sheet, suggest two papers published this week in Nature and Nature Geoscience.

An abrupt cooling event in Europe about 2,800 years ago was linked to a sustained reduction in solar radiation, reports a study published online this week in Nature Geoscience. The finding indicates that solar forcing may influence European climate over long, as well as short, timescales.
