Using nanotechnology, a team of researchers has eliminated the need for refrigeration by developing a new low-cost technique that creates a protective shield around protein biomarkers in the sample. With this method, the samples maintain 95 percent of their purity and the information on which important health-care decisions are based.
Engineers have miniaturized dual-frequency combs by putting two frequency comb generators on a single millimeter-sized silicon-based chip; could lead to low-cost, portable sensing, and spectroscopy in the field in real-time.
Biophysicists have studied the structure of a nanofibrous scaffold, as well as its interaction with rat cardiac cells. The study revealed that cardiomyocytes - heart muscle cells - envelop nanofibers as they grow, while fibroblasts - connective tissue cells - tend to spread out on fibers forming several focal adhesion sites.
Physicists have managed to alter the flow of spin waves through a magnet, using only an electrical current. This is a huge step towards the spin transistor that is needed to construct spintronic devices.
