A photonic crystal chip is illuminated with violet laser light that is patterned by a spatial light modulator. The patterned laser light effectively cancels atomic-scale disorder.  Researchers at UTS, as part of a large international collaboration, have made a breakthrough in the development of compact, low-cost and practical optical microscopy to achieve super-resolution imaging on a scale 10 times smaller than can currently be achieved with conventional microscopy.  At Caltech, a group of researchers led by Assistant Professor of Bioengineering Lulu Qian is working to create circuits using not the usual silicon transistors but strands of DNA.  Researchers have introduced a new type of "super-resolution" microscopy and used it to discover the precise walking mechanism behind tiny structures made of DNA that could find biomedical and industrial applications.  Genes tell cells what to do—for example, when to repair DNA mistakes or when to die—and can be turned on or off like a light switch. Knowing which genes are switched on, or expressed, is important for the treatment and monitoring of disease. Now, for the first time, Caltech scientists have developed a simple way to visualize gene expression in cells deep inside the body using a common imaging technology.  Researchers at The University of Manchester have discovered that a potential new drug reduces the number of brain cells destroyed by stroke and then helps to repair the damage.
