Synchrotron X-rays are frequently used to image a wide range of different materials, but they can also cause chemical changes as well. In a new study, researchers looked at how a material?s electrical resistance changes when it is irradiated with these high-energy X-rays.

Nerve agents are among the world's most feared chemical weapons, but scientists at the National Institute of Standards and Technology have demonstrated a way to engineer carbon nanotubes to dismantle the molecules of a major class of these chemicals. In principle, they say, the nanotubes could be woven into clothing that destroys the nerve agents on contact before they reach the skin.

Read moreNot only rubber is elastic: There is also another, completely different form of elasticity known as superelasticity. This phenomenon results from a change in crystal structure and was previously only found in alloys and certain inorganic materials. A Japanese scientist has now introduced the first superelastic organic compound.

'What a curious feeling', says Alice in Lewis Carroll's tale, as she shrinks to a fraction of her size, and everything around her suddenly looks totally unfamiliar. Scientists too have to get used to these curious feelings when they examine matter on tiny scales and at low temperatures: all the behavior we are used to seeing around us is turned on its head.

An international research team has built molecular 'clamps' out of DNA that offer a powerful new tool for identifying individuals with an increased risk of cancer. The clamp is capable of detecting genetic mutations, associated with cancer and other genetic diseases, with better specificity and affinity than more traditional techniques.
