Scientists at Northwestern University developed a method to construct flat or curved nanoscale structures using hybrid gold-polymer rods. The controlled assembly process holds promise for creating new materials with unique electronic and optical properties.
Proteins: From Sequence to Structure is the first book in the Primers in Biology series, covering sequence, structure, and functional properties of proteins from a post-genomic focus. The authors, Gregory Petsko and Dagmar Ringe, are authorities in their field and have received high praise for their comprehensive primer.
A University of Cincinnati biochemist has discovered that the V3 loop region of the HIV gp120 protein is structurally flexible, changing its shape as needed to bind to host cells. This finding rules out using a fixed structure as a target for anti-HIV drugs, making it harder to develop effective treatments.
Scientists have identified a class of ceramic materials that may safely contain radioactive waste for long-term storage, featuring disordered atomic structures. The fluorite-type complex oxides show promise as radiation-proof materials, warranting further development for containing nuclear wastes.
Researchers at Purdue University will study the three-dimensional structure of several types of viruses, including yellow fever and hepatitis C viruses, using a combination of X-ray crystallography and molecular biology techniques. The goal is to develop drugs that prevent infection by similar viral pathogens.
The research describes a cone-like deformation as the basic building block of a crumpled object, found in mountains and wrinkled materials. The study also reveals that crumpling is dominated by bending rather than stretching in its initial stages.
Researchers found a novel natural, very dense polymorph of silica in the Shergotty meteorite, which challenges the accepted composition of Earth's lower mantle. The discovery suggests that free dense silica polymorphs could exist in the Earth's deep interior.
Researchers used new techniques to study HDL particles, verifying the lipid bilayer structure and confirming a key finding about protein orientation. The study resolves a long-standing controversy over the structure of HDL, shedding light on its role in cardiovascular health.
Astronomers used numerical cosmology to study the earliest structures that formed in the universe, finding tiny star clusters containing 1,000-10,000 solar masses. These early clusters were likely the 'spark plugs' that started the formation of galaxies.
Researchers at the University of Limerick have developed a prototype penicillin structure that works by incorporating a unique fragment to the penicillin molecule, fatal to bacteria and activated only when cleaved. This new approach shows promise in combating antibiotic-resistant bacterial strains.
David V. Rosowsky, a Clemson civil engineering associate professor, has received the Dow Outstanding New Faculty Award for his groundbreaking work in wind engineering research and teaching.
