Into the molecular eye: Investigating liquid samples in real time

Biofilms are integral to Earth's ecology and the sustainability of life. Made up of microorganisms, biofilms play vital roles in recycling life's most essential elements. But a lack of versatile analytical tools has made ...

Delving deeper into the response of plants to drought

Drought has plagued agriculture for centuries. Scientists suspect the reason plants survive under drought may have something to do with the plant's genetic programming and metabolic activities. A recent study delved deeper ...

Calculating 'run and tumble' behavior of bacteria in groundwater

Bacteria in groundwater move in surprising ways. They can passively ride flowing groundwater, or they can actively move on their own in what scientists call "run and tumble" behavior. However, most numerical models of bacterial ...

Getting to the root of carbon storage in deep soils

Land use changes, nutrient depletion, and drought can make plant roots grow deeper into the soil. But scientists question how that growth affects carbon in the soil. Could more roots reaching deep soil layers result in more ...

Team solves decade-old mystery in chemical transformations

Researchers at Pacific Northwest National Laboratory (PNNL) have solved a mystery for a chemical reaction essential for fuel and fertilizer production. The so-called water-gas shift reaction forms hydrogen fuel and carbon ...

Better 'housekeeping' in wood-decomposing fungi

Scientists hope to harness fungi that decompose the most abundant type of biomass in wood, lignocellulose. Lignocellulose could be used to create the building-blocks of polymers for bioproducts. The key to understanding how ...

Drought spells changes for soil microbes

Researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory and Kansas State University found that soil drying significantly affected the structure and function of soil microbial communities.

Setting the stage for fuel-efficient fertilizer

Ammonia, the primary ingredient in nitrogen-based fertilizers, has helped feed the world since World War I. But making ammonia at an industrial scale takes a lot of energy, and it accounts for more than one percent of the ...

Just how resilient are biofilms?

Biofilms hold promise for generating electricity and removing contamination from groundwater, but they also threaten many industrial processes and human health. As the environment changes in which these biofilms thrive, it ...

The influence of microbes on soil respiration

Millions of microbes living in the soil could influence how soils respond to temperature changes. They also influence the amount of carbon dioxide soils give off or respire. Yet scientists rarely consider these microbes when ...
