Close-up visualizations of (A) the HOMO and (B) LUMO single-particle electron states in the 64CaO glass. Both states are spin-degenerate, and h1 labels the cavity (cage) occupied by LUMO. Yellow and magenta stand for different signs of the wave-function nodes. (C) Simulation box and the electron spin-density of the 64CaO glass with one oxygen subtracted at h2—that is, with two additional electrons. The two electrons have the same spin and they occupy separate cavities, h1 (boundary, also shown in B) and h2 (center, location of removed oxygen), which are separated by 12 Å from each other. (D) Cage structure around the spin-density of one electron cor- responding to the h2 cavity (close-up from C). Al, gray; Ca, green; O, red. To view a larger version of the image, click on it.
The formula for turning cement into metal

In a move that would make the Alchemists of King Arthur’s time green with envy, scientists have unraveled the formula for turning liquid cement into liquid metal. This makes cement a semi-conductor and opens up its use in the profitable consumer electronics marketplace for thin films, protective coatings, and computer chips.

The researchers demonstrated their new technique for creating an HIV vaccine by engineering a compound that has promise to initiate an otherwise rare immune response against many types of HIV. Here, the germline-targeting immunogen eOD-GT6 (red) is shown bound to its target, the germline VRC01 antibody (magenta and yellow). To view a larger version of the image, click on it.

X-ray analysis could boost legumes, thus reducing fertilizer pollution

The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment. An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with traditionally poor soil quality.
