Science Highlights

This image shows Bisophere 2 (a), which houses a tropical rainforest (b) where researchers performed an ecosystem-scale drought experiment. Researchers labeled the soil (c) to track the release of carbon dioxide and volatile organic compounds.

During Droughts, Soil Microbes Produce Volatile Carbon Metabolites

In a warmer world, microbes in drought-stricken soils convert less carbon to carbon dioxide and more to volatile intermediates.

Images of Yarrowia lipolytica surrounding and growing on polyolefin oil droplets (large red circles). Cells were stained blue to show the chitin cell walls and red to show the lipid bodies inside the cells and the oil droplets outside the cells.

Yeast Uses Plastic Waste Oils to Make High-Value Chemicals

Yarrowia lipolytica reallocates its production of protein toward energy and lipid metabolism to grow on hydrocarbons and produce high-value chemicals.
