Dye-doped DNA nanofibers emit white light
A team of researchers at the University of Connecticut and the US Air Force Research Laboratory has now successfully used the electrospinning of DNA complexes to produce nanofibers that incorporate two different fluorescing dyes in such a way that energy can efficiently be transferred from one dye to the other. The color of the resulting fluorescence can be controlled by means of the ratio of the two dyes.

Read moreNew metamaterial brings us nearer to the dream of invisibility
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light by making the inside of the magnetic field zero but not altering the exterior field. The device, which up to date has only been studied in theoretical works, thus acts as an invisibility cloak, making the object completely undetectable to these waves.

Features in the July issue of Physics World include a close look at how physics is informing our understanding of cells and of the brain, while Paul Davies, a physicist, astrobiologist and director of BEYOND: Center for Fundamental Concepts in Science at Arizona State University, suggests there are tentative signs that life itself may have arisen as a result of physicists' long-cherished theory of quantum mechanics.

The Environmental Working Group (EWG), a United States-based non-governmental organization that works to expose threats to health and the environment, has released their 2009 Sunscreen Report. The investigators expected to recommend against the use of micronized and nano-sized zinc oxide and titanium dioxide sunscreen, but after months of research and analysis of nearly 400 peer-reviewed studies, they found themselves recommending some sunscreens that may contain nanoparticles.
