A new coating developed by Sandia National Laboratories has increased sensor sensitivity by a factor of about 500, making it ideal for detecting dangerous molecules in the air or water. This technology could aid in combatting terrorism and also benefit industries such as oil and pharmaceuticals.
Researchers found that individual polymer vibrations can be accurately described by a linear theory, similar to the vibrations of a musical string. The study used DNA strands and optical tweezers to analyze their movements, finding a high accuracy rate of over 1 percent up to the eighth harmonic.
Researchers have discovered that tiny clusters of eight water molecules naturally arrange themselves into small cubic structures, revealing unique properties of water. The study found that even in very small water clusters, water has the capacity to arrange its hydrogen bonds in several distinct orientations.
Protein binding events control many biological processes; removing water from binding sites provides energy that drives reactions. Duke researchers used a supersensitive instrument to measure minute temperature changes in normal and heavy water to separate protein-water interactions from ligand-water interactions.
Research by Penn State scientists has shown that humus can bind up to 40-50% of applied chemicals, including pesticides and other pollutants, rendering them unavailable to plants or groundwater. This natural process is beneficial as bound chemicals are stable and do not leach into the environment.
Researchers have identified a molecule that allows bacteria to resist an unusually wide range of drugs, including those with different chemical properties. This discovery highlights the dormant potential of some bacteria to survive complex antibiotic treatments.
Purdue University scientists have developed a method to trap and study ions on surfaces, providing a new way to alter materials at the nanoscale level. The technique uses molecular ions that can be selected based on mass, allowing for reversible surface modification and preserving the ions.
Researchers at NYC's Metropolitan Museum of Art and Sandia National Laboratories have created an inorganic coating that increases powdered calcite's longevity by a factor of ten when exposed to mildly acidic rain. The coating, chemically similar to glass, strengthens masonry without repelling water.
A team of scientists led by Jennifer Doudna solved the 3D structure of a large portion of an RNA enzyme, revealing its ability to trigger cell activity and potentially provide the first method for genetic reproduction. This breakthrough could help design new drugs to fight lethal viruses and repair genetic errors.
Microgravity researchers Michael Paulaitis and Kathleen Stebe are developing stable suspensions to create polymers in Earth-based labs. Their findings could shape space station materials, fuel pumping systems, and pharmaceutical manufacturing.
