Scientists have measured records of wood flowing to reservoirs and coastal regions to estimate the magnitude of global wood movement.

New research into the design of catalysts has shown that hydrogen can be cleanly produced with much greater efficiency and at a lower cost than is possible with current commercially available catalysts.

Too often, strategies proven in research studies to reduce pediatric obesity are never implemented in the 'real world.' Researchers describe a school-based program that gets these interventions across the finish line by inviting schools to tailor them to their own needs. Thanks to this flexible approach, 200 schools in South Carolina have signed on and seen improvements in both health and educational outcomes.

When cells within a single tumor differ in terms of their genetic makeup, this is referred to as intratumor heterogeneity. Researchers have been able to reconstruct the process by which this genetic heterogeneity develops in neuroblastoma, a type of cancer which primarily affects young children. According to their findings, the genetic makeup of individual tumors shows marked spatial and temporal variability.

Across the U.S. road crews dump around 25 million metric tons of sodium chloride -- much like table salt -- to unfreeze roads each year and make them safe for travel.
