For the last two decades, magnetic tunnel junctions (MTJs) have played a central role in spintronic devices such as read heads of hard disk drives and nonvolatile magnetoresistive random access memories (MRAMs), and researchers are constantly working to improve their performance.  Magnetic materials are a vital ingredient in the components that store information in computers and mobile phones. Now, A*STAR researchers have developed a material that could help these magnetic-based memory devices to store and retrieve data faster while using less power.  A team of researchers with members from institutions in Germany and Israel has developed a way to launch plasmons with controlled amounts of angular momentum using spiral-like structures fashioned into a smooth layer of gold plate.  Work at the New York Genome Centre represents a big step towards DNA-based information storage. Andrew Masterson reports.  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.  Researchers at the University of Connecticut have uncovered new information about how particles behave in our bloodstream, an important advancement that could help pharmaceutical scientists develop more effective cancer drugs.
