Chemistry World May 21, 2012 Rachel Cooper	Bromine anion caught in a supramolecular trap Scientists in the UK and China have encapsulated a bromine anion in a supramolecular cavity to make a compound that could act as a model for metal-/anion-doped TiO 2.
Chemistry World May 17, 2012 David Bradley	Plutonium in a Spin Spectroscopists have finally pinned down the nuclear magnetic resonance spectrum of plutonium-239. The finding might point the way to improved approaches to the long-term storage of nuclear waste.
Chemistry World May 15, 2012 James Mitchell Crow	Polymer gel squeezes and strains like an intestine Researchers have found that the oscillating chemical waves of the Belousov-Zhabotinsky reaction are strong enough to carry a cargo, driving it along a length of smart polymer tubing using contractions - just like an intestine.
Chemistry World May 14, 2012 Josh Howgego	Powering up retinal prosthetics Scientists are reporting a futuristic design for retinal prostheses, which, in principle, would dramatically simplify the surgical procedure required to return sight to the blind.
Chemistry World May 10, 2012 Holly Sheahan	Forensic electrochemistry to detect firearms use A group led by Joe Wang at the University of California-San Diego, USA has developed a new forensic technique that can detect gunshot residue at the scene of the crime.
Chemistry World May 9, 2012 Simon Hadlington	Disposable paper electronic touch pads on their way Researchers in the US and France have developed a paper-based electronic touch pad, opening the way for low cost, throwaway touch pads to be incorporated into anything from food packaging to disposable or sterile medical devices.
Chemistry World May 1, 2012 David Bradley	A colorful way to size up nanoparticles Researchers in China have now developed a straightforward light-scattering technique to estimate the size of gold nanoparticles in the 35 to 110nm range.
IEEE Spectrum May 2012 Rachel Courtland	The Kilogram, Reinvented Two difficult experiments are poised to remake one of the world's most fundamental units
IEEE Spectrum May 2012 Alexander Hellemans	A New Twist on Radio Waves Using the angular momentum of light could make one radio channel into two, three, or more. But many wireless experts are skeptical
IEEE Spectrum May 2012 Samuel K. Moore	Landauer Limit Demonstrated Scientists show that a 50-year-old principle limiting future CMOS computing is real: Erasing information gives off heat
