DNA nanoswitches reveal how life's molecules connect: An accessible new way to study molecular interactions could lower cost and time associated with discovering new drugs

A complex interplay of molecular components governs almost all aspects of biological sciences - healthy organism development, disease progression, and drug efficacy are all dependent on the way life's molecules interact in the body. Understanding these bio-molecular interactions is critical for the discovery of new, more effective therapeutics and diagnostics to treat cancer and other diseases, but currently requires scientists to have access to expensive and elaborate laboratory equipment.

The color scale in this image from the Planck mission represents the emission from dust, a minor but crucial component that pervades our Milky Way galaxy. The texture indicates the orientation of the galactic magnetic field. It is based on measurements of the direction of the polarized light emitted by the dust.

Detecting chemical weapons with a color-changing film

In the world, in which the threat of terrorism looms, there is an urgent need for fast, reliable tools to detect the release of deadly chemical warfare agents (CWAs). Scientists are reporting new progress toward thin-film materials that could rapidly change colors in the presence of CWAs -- an advance that could help save lives and hold aggressors accountable.

Carbon nanoballs can greatly contribute to sustainable energy supply

Researchers at Chalmers University of Technology have discovered that the insulation plastic used in high-voltage cables can withstand a 26 per cent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system.
