Some rocks can float on water for years at a time before eventually sinking. X-ray microtomography studies help explain how by scanning samples of lightweight, glassy, and porous volcanic rocks known as pumice stones. Their surprisingly long-lived buoyancy can help scientists discover underwater volcano eruptions. ... Read more »
Scientists have sequenced the genome of a green alga that has drawn commercial interest as a strong producer of quality lipids for biofuel production. The chromosome-assembly genome of Chromochloris zofingiensis provides a blueprint for new discoveries in sustainable biofuels, antioxidants, and other valuable bioproducts. ... Read more »
The veins of living leaves at increasing levels of drought stress were visualized using x-ray microtomography. The results expand our view of leaf drought responses, beyond the traditional embolism-centric view, to a broader focus on the role of the surrounding living tissues in water movement during drought. ...
