A synthetic compound long known to exhibit interesting transition properties may hold the key to new, non-magnetic forms of information storage, say researchers at the RIKEN SPring-8 Center and their collaborators. The team's latest findings shed light on the complex relationship between a compound's electron spin arrangement and its transport properties, an area researchers have long struggled to understand.

By Helen Shen of Nature magazine The nerves in a human brain form a three-dimensional grid of criss-crossing fibers, say researchers who have mapped them. The regular pattern creates a scaffold to guide brain development and support more complex and variable brain structures, says Van Wedeen, a neuroscientist at the Massachusetts General Hospital in Boston.

Snowpack in the northern Rocky Mountains has shrunk at an unusually rapid pace during the past 30 years, according to a new study. The decline is "almost unprecedented" over the past 800 years, say researchers who used tree rings to reconstruct a centuries-long record of snowpack throughout the entire Rocky Mountain range
