Boosting butanols role in the biofuel world

Butanol is the go-to industrial solvent for products such as lacquers and enamels, but it might also play a substantial role in the production of renewable fuels. Gallon for gallon, it has 30 percent more energy than ethanol ...

Alaska shows no signs of rising Arctic methane

Despite large temperature increases in Alaska in recent decades, a new analysis of NASA airborne data finds that methane is not being released from Alaskan soils into the atmosphere at unusually high rates, as recent modeling ...

Granular model explains unusual behavior in sand

From a mechanical perspective, granular materials are stuck between a rock and a fluid place, with behavior resembling neither a solid nor a liquid. Think of sand through an hourglass: As grains funnel through, they appear ...

NASA Commercial Crew partners continue system advancements

NASA's industry partners continue to complete development milestones under agreements with the agency's Commercial Crew Program. The work performed by Blue Origin, Boeing, Sierra Nevada Corporation and SpaceX during partnership ...

Saving Christmas Island's reptiles

Environmental scientists are working alongside park rangers to protect Christmas Island's remaining reptilian wildlife from extinction.

Researchers discern the shapes of high-order Brownian motions

For the first time, scientists have vividly mapped the shapes and textures of high-order modes of Brownian motions—in this case, the collective macroscopic movement of molecules in microdisk resonators—researchers at ...

Evolutionary constraints revealed in diversity of fish skulls

In the aquatic environment, suction feeding is far more common than biting as a way to capture prey. A new study shows that the evolution of biting behavior in eels led to a remarkable diversification of skull shapes, indicating ...
