A glimpse into the nanoworld of lymphocyte cell membranes

Researchers have applied super-resolution methods to study the organization of receptors on B lymphocytesAntigen receptors on B lymphocytes sense foreign molecules, such as pathogens or vaccines, and activate the B cells to produce antibodies that protect humans against many diseases.

New way to repair nerves: Using exosomes to hijack cell-to-cell communication

Biomedical engineers report a new way to induce human mesenchymal stem cells to differentiate into neuron-like cells: treating them with exosomes from rat-derived progenitor cells. In combination with synthetic nanoparticles now in development, researchers hope to make synthetic exosomes, inducing neuron growth without neural progenitor cells.

Tracking slow nanolight in natural hyperbolic metamaterial slabs

Scientists have imaged how light moves inside an exotic class of matter known as hyperbolic materials. They observed, for the first time, ultraslow pulse propagation and backward propagating waves in deep subwavelength-scale thick slabs of boron nitride - a natural hyperbolic material for infrared light.
