(NIH/National Eye Institute) By combining two imaging modalities -- adaptive optics and angiography -- investigators at the National Eye Institute (NEI) can see live neurons, epithelial cells, and blood vessels deep in the eye's light-sensing retina. Resolving these tissues and cells in the outermost region of the retina in such unprecedented detail promises to transform the detection and treatment of diseases such as age-related macular degeneration (AMD), a leading cause of blindness among the elderly.

(University of Arizona College of Engineering) By developing stronger and more stable phase change material -- the stuff that holds the data stored on microchips and rewritable CDs -- researcher Pierre Lucas brings us closer to a reality where data storage systems operate like artificial neural networks.

(University of California - Berkeley) A new flexible sensor developed by engineers at the University of California, Berkeley, can map blood-oxygen levels over large areas of skin, tissue and organs, potentially giving doctors a new way to monitor healing wounds in real time. The sensor is made of organic electronics printed on bendable plastic that molds to the contours of the body.

(Linköping University) Researchers at Linköping University, Sweden, are working to develop a method to convert water and carbon dioxide to the renewable energy of the future, using the energy from the sun and graphene applied to the surface of cubic silicon carbide. They have now taken an important step towards this goal, and developed a method that makes it possible to produce graphene with several layers in a tightly controlled process.

(University of Pennsylvania) A team of Penn Engineers has demonstrated a new material they call 'nanocardboard,' an ultrathin equivalent of corrugated paper cardboard. A square centimeter of nanocardboard weighs less than a thousandth of a gram and can spring back into shape after being bent in half. Nanocardboard's stiffness-to-weight ratio makes it ideal for aerospace and microrobotic applications, where every gram counts.

(Arizona State University) In new research appearing in the journal Nature Communications, Hao Yan and his colleagues Fei Zhang, Xiaodong Qi and others describe a method for coaxing segments of single-stranded DNA into complex 2- and 3D knotted structures.

(University of California - Riverside) A team of physicists and a virologist, led by a scientist at the University of California, Riverside, explains how large virus shells are formed. Their work can also be used also to explain how large spherical crystals form in nature. This understanding may help researchers interrupt viruses' formation, containing the spread of viral diseases.
