Researchers Discover Silver Nano-Cluster DNA Probes for Disease Detection

Many diseases, including cancers, leave genetic clues in the body just as criminals leave DNA at the scene of a crime. But tools to detect the DNA-like sickness clues known as miRNAs, tend to be slow and expensive.

Chinese Researchers Study Nano-Scale Deformation of Crack Tip

The fracture of materials is a very important issue for both structural and functional materials. Crack-tip behavior is among the most basic problems in fracture mechanics. Many theoretical and experimental investigations have been carried out to understand the effect of crack-tip deformation fields.

Vienna University Researchers Study Catalytic Converter Efficiency Using Electron Microscope

Catalytic converters work poorly if they have not yet warmed up. Tiny metal particles in a catalytic converter require a minimum temperature to function efficiently. At the Vienna University of Technology, thanks to a new measuring method, it has now become possible to examine many different types of these particles at the same time. Reliable information regarding what it is exactly that the efficiency of catalytic converters depends on has thus been obtained for the first time.

Researchers Discover Tiniest and Fastest-Known RNA Switches

A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting structures are prime targets for the development of new antiviral and antibiotic drugs.
