How do silt and sand differ when going with the flow?
Sand and silt in rivers dramatically change their means of transport at a sharp boundary between grain sizes, regardless of how fast the river...
Resident orcas’ appetite likely reason for decline of big Chinook salmon
Large, old Chinook salmon have mostly disappeared from the West Coast. A new study points to the recent rise of resident killer whales, and...
Hard as a rock? Maybe not, say bacteria that help form soil
Scientists show how bacteria can degrade solid bedrock, jump-starting a long process of alteration that creates the mineral portion of soil.
Uncertain role of natural gas in the transition to clean energy
A new study examines the opposing roles of natural gas in the battle against climate change -- as a bridge toward a lower-emissions future,...
Planetary boundaries: Interactions in Earth system amplify human impacts
Transgressing one planetary boundary can amplify human impacts on another one. For the first time, an international team of scientists now quantified some of...
Neutrons optimize high efficiency catalyst for greener approach to biofuel synthesis
Researchers used neutron scattering in the development of a catalyst that converts biomass into liquid fuel with remarkably high efficiency and provides new possibilities...
Underwater pile driving noise causes alarm responses in squid
Exposure to underwater pile driving noise, which can be associated with the construction of docks, piers, and offshore wind farms, causes squid to exhibit...
Big step in producing carbon-neutral fuel: Silver diphosphide
A new chemical process does in the lab what trees do in nature -- it converts carbon dioxide into usable chemicals or fuels.
Artificial intelligence may help scientists make spray-on solar cells
Artificial Intelligence may be just the thing to accelerate spray-on solar cell technology, which could revolutionize how consumers use energy. A research team has...
Tiny shells reveal waters off California are acidifying twice as fast as the global...
In first-of-its-kind research, scientists used 100 years of microscopic shells to show that the coastal waters off California are acidifying twice as fast as...
