  • Building 'smart' cell-based therapies

    A technology for engineering human cells as therapies has been developed by scientists. The the technology becomes activated only in diseased tissues. It sits on the surface of a cell and Connect Error:Too many connectionsdb error can be programmed to sense specific external factors. For example, the engineered cell could detect big, soluble protein molecules that indicate that it's next to a tumor. When the biosensor detects such a factor, it sends a signal into the engineered cell's nucleus to activate a gene expression program, such as the production of tumor-killing proteins or chemicals.
  • Thinnest membrane feasible has been produced

    A new nano-membrane made out of the 'super material' graphene is extremely light and breathable. Not only can this open the door to a new generation of functional waterproof clothing, but also to ultra-rapid filtration. The new membrane just produced is as thin as is technologically possible.
  • Chiral breathing: Electrically controlled polymer changes its optical properties

    Electrically controlled glasses with continuously adjustable transparency, new polarization filters, and even chemosensors capable of detecting single molecules of specific chemicals could be fabricated thanks to a new polymer unprecedentedly combining optical and electrical properties.
  • Global scientific team 'visualizes' a new crystallization process

    By combining a synchrotron's bright X-ray beam with high speed X-ray cameras, scientists shot a 'movie' showing how organic molecules form into crystals. This is a first. Their new techniques will improve our understanding of crystal packing and should help lead to better electronic devices as well as pharmaceuticals -- indeed any product whose properties depend on precisely controlling crystallization.
  • Relieving electric vehicle range anxiety with improved batteries

    A new nanomaterial called a metal organic framework could extend the lifespan of lithium-sulfur batteries, which could be used to increase the driving range of electric vehicles. Researchers added the powder, a kind of nanomaterial called a metal organic framework, to the battery's cathode to capture problematic polysulfides that usually cause lithium-sulfur batteries to fail after a few charges. During lab tests, a lithium-sulfur battery with the new MOF cathode maintained 89 percent of its initial power capacity after 100 charge-and discharge cycles.
