Research shows that the use of corn ethanol reduces the carbon footprint and diminishes greenhouse gases.
Rice University physicists make unique broadband polarization rotators with ultrathin carbon nanotube films. The rotators extend to the terahertz, which could simplify devices for use in telecommunications, security and manufacturing.
Juvenile salmon migrating to the sea in the Sacramento River face a gauntlet of hazards in an environment drastically modified by humans, especially with respect to historical patterns of stream flow. Now fisheries scientists have identified key thresholds in the relationship between stream flow and salmon survival that can serve as actionable targets for managing water resources in the Sacramento River.

The amount of nutrients people get from the crops that they eat is a type of 'postcode lottery', according to new research that has analysed thousands of cereal grains and soils as part of a project to tackle hidden hunger in Malawi and Ethiopia.
Current fertilization practices and over simplified nutrient recommendations are directly tied to Nepal's declining rice yields; researchers used a promising new tool to bridge the productivity gap through a more precise, farmer-participatory approach.
