These liquid-filled scaffolds are not enclosed, but they don’t leak.

Inspired by the way plants absorb and distribute water and nutrients, researchers at Lawrence Livermore National Laboratory (LLNL) have developed a method for transporting liquids and gases using capillary action and a 3D-printed lattice. In a paper published in Nature, researchers describe 3D-printed microstructures capable of creating controlled contact between liquid and gas. The porous, open-cell structures use capillary action, driven by surface tension, to create and control the flow of both. Researchers said the technique could have broad-ranging impacts on numerous fields involving mu...

The popular Lawrence Livermore National Laboratory's lecture series for middle and high school students, "Science on Saturday," is going virtual this year with the theme “Combating COVID-19.” The free, online lectures, featuring leading LLNL researchers joined by Bay Area science teachers, are scheduled for 10 a.m., on four consecutive Saturdays, beginning Feb. 6. Each of the lectures will address a difference aspect of the scientific effort to combat the coronavirus. Feb. 6 - “Molecular Diagnostics in the Age of COVID: Designing a Portable Point-of-Care Device.” Presented...
