Study finds simple changes in road resurfacing practices could improve gas mileage for heavy vehicles and reduce greenhouse gas emissions.

Technique paves the way for more energy efficient, 3D microprocessors.

Lightweight, flexible materials can be used to make health-monitoring wearable devices, but powering the devices is a challenge. Using fuel cells instead of batteries could make the difference.

Carbon nanotubes embedded in leaves detect chemical signals that are produced when a plant is damaged.

Monitoring the plant hormone ethylene could reveal when fruits and vegetables are about to spoil.

Carbon nanotube film produces aerospace-grade composites with no need for huge ovens or autoclaves.

The process could work on the gas at any concentrations, from power plant emissions to open air.

New technique could enable assembly of circuit boards and displays with more minute components.

Made from carbon nanotubes, the new coating is 10 times darker than other very black materials.

New approach harnesses the same fabrication processes used for silicon chips, offers key advance toward next-generation computers.
