(Medical Research Council) Scientists have equipped a virus that kills carcinoma cells with a protein so it can also target and kill adjacent cells that are tricked into shielding the cancer from the immune system. It is the first time that cancer-associated fibroblasts within solid tumors -- healthy cells that are tricked into protecting the cancer from the immune system and supplying it with growth factors and nutrients -- have been specifically targeted in this way.

(University of California - Berkeley) A single season of high school football may cause microscopic changes in the structure of the brain, according to a new study by researchers at the University of California, Berkeley, Duke University and the University of North Carolina at Chapel Hill. A new type of magnetic resonance imaging (MRI) revealed significant changes in the structure of the grey matter in the front and rear of the brain and changes to structures deep inside the brain.

(Rice University) A 'smart skin' developed at Rice University employs the unique fluorescent characteristics of carbon nanotubes to quickly assess strain in materials. The method is intended for aircraft, spacecraft and critical infrastructures in which mechanical strain needs to be monitored.

(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.
