The sugar trehalose helps microorganisms to withstand drought conditions, but the mechanism by which this occurs is poorly understood. An investigation of the holes in the different structural forms of the sugar could provide clues as to how this bioprotection is possible.
A combination of computer simulation and experimental work has shown that the growth of dendritic structures during solidification is more complex than previously thought.
We have begun to understand the physical determinants of cell rheology and their relevance to biological functions. Experiments performed on freshly excised cells offer a new perspective in which soft-glass rheology and prestress seem to play central roles.
Artificial materials composed of either structured or random subunits far below the wavelength of light can be designed to display fascinating physical properties. Recent advances in fabrication technology have established the great potential of such metamaterials for applications.
A novel X-ray diffraction technique opens the way to investigate deformation-induced dislocation microstructures with submicrometre resolution.
Nature Materials 5, 517–518 (2006) doi: 10.1038/nmat1679 In this News and Views article, the page numbers of the Letter under discussion — J. R. Wilson et al. Nature Materials 5, 541–544; 2006 — were missing in the pdf and print versions.
Field-effect transistors are emerging as useful device structures for efficient light generation from a variety of materials, including inorganic semiconductors, carbon nanotubes and organic thin films. In particular, organic light-emitting field-effect transistors are a new class of...
