? Build 'em small??The shells of microscopic ocean creatures could be the inspiration for a new approach to building components for a wide range of technologies from the lab-on-a-chip to miniature medical devices.
? Shedding light on quantum dots??Hybridising an inorganic nanocrystal and a quantum dot lead to a quantum dot-organic light-emitting device (QD-OLED) a new kind of optoelectronic device that could lead to new types of flat panel displays to supersede liquid crystal displays in everything from mobile devices to TV sets.
? Alloys spring to mind??A wide range of other Ni-Mn-Ga alloys that exhibit "shape memory" but also magnetic properties have been found by Japanese scientists using a combinatorial approach.
? Marine bugs make drugs?Marine actinomycetes, the sea-going counterparts of soil-dwelling microbes, make some highly biologically active substances. A US team has recently discovered a new antitumor agent in one of these marine bacteria and by exploiting X-ray diffraction and spectroscopy have determined its precise structure, offering a new target for synthetic chemists to focus on.
