Issues

Chip makers have a mantra: smaller, cheaper, and faster. They may now need a new adjective—taller.

Submicron spin textures in bulk magnetic materials have been stubbornly hard to detect.

Theorists have tested what seemed like an untestable conjecture: that all the possible arrangements of grains in a packing are equally probable.

Improved models, new icebreakers, and more observations are needed to gauge global effects of the polar region’s diminishing ice cover.

Barring a reversal, government–academia research networks will lapse and facilities in the high Arctic will shut down.

Although the cost of fuel cells has rapidly decreased, the lack of a fueling infrastructure limits their use in vehicles.

Many physiological systems must work together to enable movement in animals and other organisms. Neuromechanics explores how those systems interact with each other and the environment.

A concise packet of lecture notes offers a window into one of the turning points of 20th-century history.

Lens-free on-chip imaging devices provide cost-effective, compact, and wide-field microscopy solutions for fieldwork and global health applications.

Counterintuitive phenomena arise from the interfacial and surface forces that operate in heat pipes. But we had to eliminate gravity to see them.
