Not just for raincoats

Researchers from Northwestern University and the Massachusetts Institute of Technology (MIT) have studied individual water droplets and discovered a miniature version of the "water hammer," an effect that produces the familiar radiator pipe clanging...

A nanoscale rope, and another step toward complex nanomaterials that assemble...

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have coaxed polymers to braid themselves into wispy nanoscale ropes that approach the structural complexity of biological materials. Their work is t...

Tougher rating system evaluates nine supercomputer capabilities

Learning how consumers value products

Suggesting to consumers that they will use a product frequently can actually reduce their interest in purchasing the product, according to a new study in the Journal of Consumer Research. "When consumers estimate the value of a durable product, th...

Tiny MAVs may someday explore and detect environmental hazards

Air Force Office of Scientific Research-sponsored researcher, Dr. Robert Wood of Harvard University is leading the way in what could become the next phase of high-performance micro air vehicles for the Air Force. His basic research is on tr...
