• It's elemental: Ultra-trace detector tests gold purity
  

  Unless radon gas is discovered in a home inspection, most people remain blissfully unaware that rocks like granite, metal ores, and some soils contain naturally occurring sources of radiation. In most cases, low levels of radiation are not a health concern. But some scientists and engineers are conc more

• Novel materials convert visible into infrared light
  

  Columbia University scientists, in collaboration with researchers from Harvard, have succeeded in developing a chemical process to convert visible light into infrared energy, allowing innocuous radiation to penetrate living tissue and other materials without the damage caused by high-intensity light more

• New composite material that can cool itself down under extreme temperatures

  A cutting-edge material, inspired by nature, that can regulate its own temperature and could equally be used to treat burns and help space capsules withstand atmospheric forces is under development at the University of Nottingham. "A major challenge in material science is to work out how to regulate more

A Guide to the Different Types of Radiation

We’re venturing tentatively into the border region between chemistry & physics today, with a look at some of the different types of nuclear radiation. These types vary in their composition, characteristics, and uses, but here’s an attempt to sum up the most common in one succinct graphic. One thing more

• Solar UV radiation and microbial life in the atmosphere

  Many microorganisms are alive while suspended in the atmosphere, and some seem to be metabolically active during their time there. One of the most important factors threatening their life and activity is solar ultraviolet (UV) radiation. Quantitative understanding of the spatial and temporal surviva more
