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 »
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. ...

Lubricants help keep civilization running smoothly, but is there room for improvement? With the goal of increasing the life span and lowering the costs of all kinds of mechanical and biological systems, researchers used x-ray microtomography to visualize the behavior of grease additives under working conditions. ...

In grapevines, “root pressure” was assumed to play a role in recovering from embolisms (blockages) in a plant’s water-transport systems during drought conditions. To clarify this, researchers used ALS Beamline 8.3.2 to obtain 3D microtomographic images of grapevine stem segments detached from roots and leaves. ... Read more »
Using a combination of high-speed video, molecular phylogenetic analysis, and x-ray microtomography of a family of tiny trap-jaw spiders, researchers discovered that power-amplified predatory strikes evolved four times independently, once the basic trap-jaw body plan was in place. ... Read more »
Lithium-ion batteries, popular in today’s electronic devices, could gain significant energy density if their graphite anodes were replaced with lithium metal anodes. But there’s a major concern with substituting lithium—when the battery cycles, microscopic fibers of the lithium anodes (“dendrites”) form on the surface of the lithium electrode and spread across the electrolyte until they reach the other electrode, possibly leading to short circuiting. Researchers have recently discovered that the x-ray microtomography capabilities at ALS Beamline 8.3.2 can give them a novel view of dendrite growth that’s likely to provide the insight needed to stop it.
