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.

Because of their potential to reduce costs for both fabrication and materials, organic photovoltaics could be much cheaper to manufacture than conventional solar cells and have a smaller environmental impact as well. To view a larger version of the image, click on it.
Scientists detect residue that has hindered efficiency of promising type of solar cell

Argonne researchers have for the first time been able to detect trace residues of catalyst material on organic photovoltaics.

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.

Antibody evolution could guide HIV vaccine development

According to a recent study, observing the evolution of a particular type of antibody in an infected HIV-1 patient has provided insights that will enable vaccination strategies that mimic the actual antibody development within the body.

NDM-1, present in a number of pathogenic bacteria, including Klebsiella pneumonia and Escherichia coli, is able to defeat many of the world’s most widely used antibiotics, including penicillin derivatives, cephalosporins, monobactams and carbapenems.
Breakthrough could lead to drugs that better combat 'superbugs'

In the never-ending battle between antibiotic developers and the bacteria they fight, scientists at Argonne have made a key breakthrough that could allow for the development of new drugs to more effectively combat antibiotic-resistant “superbugs.”
