Sawdust reinvented into super sponge for oil spills

Lowly sawdust, the sawmill waste that's sometimes tossed onto home garage floors to soak up oil spilled by amateur mechanics, could receive some new-found respect thanks to science.

A new model for microbial communities in the hyporheic zone

Ecological processes govern seasonal changes in microbial communities living along rivers in the hyporheic zone, where groundwater and surface water mix. These processes have been well-studied in plant and animal communities. ...

Solving mysteries of how water works

Many phenomena depend on the connectivity of hydrogen bonds. Scientists have strived to unlock mysteries about how the network of hydrogen bonds in water controls its behavior since 1806 when Theodor Grotthuss published his ...

Catching more carbon with less sticky solvents

For coal- and natural-gas-fired power plants, scientists want a liquid that captures carbon dioxide. But the water-lean solvents they prefer thicken to the consistency of cold honey the more carbon they catch. Finding better ...

Vital interplay between microorganisms and extracellular minerals

Some minerals abundant in soils and in aquatic and subsurface sediments electronically support microbial growth by supplying electrons or storing them as "environmental batteries," according to this new review article. Microbial ...
