The three peptides shown in the shaded box are currently being experimentally validated by the Baker Laboratory. For comparison, the peptides are shown with the small molecule that is the active agent in aspirin and a large protein that is used as an anti-HIV antibody.
Software optimized on Mira advances design of mini-proteins for medicines, materials

Scientists at the University of Washington are using Mira to virtually design unique artificial peptides, or short proteins. As the researchers begin to develop new peptides, they are optimizing their in-house software to test thousands of potential peptide structure designs in tandem, requiring a state-of-the-art supercomputer.

10 highlights celebrating 10 years of Argonne Leadership Computing Facility

The Argonne Leadership Computing Facility turns 10 years old this week. Here are 10 highlights to celebrate its first decade of accomplishments.

(a) X-rays from the APS interact with cerium jets and impact a scintillator that converts the X-rays to visible light, while photonic Doppler velocimetry (PDV) probes simultaneously measure jet-growth velocities. Four intensified charge-coupled device (ICCD) detectors then capture the optically multiplexed images. (b) Multiple images of a jet as it crosses the field-of-view of the ICCD detectors. The groove in the back of the cerium sample is shown on the left. (courtesy of Brian Jensen, Los Alamos National Laboratory)
Jets reveal cerium’s shocked strength

"Jets” formed after shockwaves passed through cerium metal provided the yield stress of cerium in its post-shock state, indicating the stress that would cause it to become permanently deformed.

Researchers at Argonne’s Center for Nanoscale Materials have confirmed the growth of self-directed graphene nanoribbons on the surface of the semiconducting material germanium by researchers at the University of Wisconsin at Madison. (Click on image to enlarge.)
One Direction: Researchers grow nanocircuitry with semiconducting graphene nanoribbons

Researchers from the University of Wisconsin at Madison are the first to grow self-directed graphene nanoribbons on the surface of the semiconducting material germanium. This allows the semiconducting industry to tailor specific paths for nanocircuitry in their technologies. The findings were confirmed at Argonne’s Center for Nanoscale Materials.

‘Greener’ way to assemble materials for solar applications

Polymers used in solar cells today require solvents that can harm the environment, but scientists using the Advanced Photon Source at Argonne have found a “greener” way to control the assembly of photovoltaic polymers in water using a surfactant— a detergent-like molecule—as a template.

Researchers have measured how the atoms within electrically insulating solids reorient due to an applied electric field. Shown here for Na1/2Bi1/2TiO3, bismuth ions (purple) align along the electric field direction relative to their surrounding titanium ions (blue). Oxygen ions not shown. (Click image to enlarge.)
