TL;DR: Dawn observations confirm the large impact basin at Vesta's south pole and reveal evidence for an earlier, underlying large basin (Veneneia), underscoring Vesta’s unique role as a transitional solar system body.

TL;DR: In this paper, the porous matrix of natural wood is deconstructed to form a homogeneous cellulose-lignin slurry that features nanoscale entanglement and hydrogen bonding between the regenerated lignin and cellulose micro/nanofibrils.

TL;DR: Data show that there was new material after impact that was compositionally different from that seen before impact, and the ratio of dust mass to gas mass in the ejecta was much larger than before impact.

TL;DR: A novel scalable aesthetic transparent wood with integrated functions of optical transparency, UV-blocking, thermal insulation, and mechanical strength for this sustainable application is demonstrated.

TL;DR: This work demonstrates a strong, lightweight bio-based structural material derived from bamboo via a two-step manufacturing process involving partial delignification followed by microwave-heating, demonstrating outstanding mechanical properties with a nearly 2-times improved tensile strength, 3.2-times enhanced toughness, and 2- times increased bending strength compared to natural bamboo.
