A new approach to send 'friendly' nano-particles into a patient's blood stream has shown promising results by modifying the surface of these potential drug, vaccine or cancer treatment delivery objects to encourage the best result. Scientists are testing the body's responses to various surface treatments to nanomaterials.

Researchers have demonstrated a prototype glasses-free 3D light field display system with a significantly extended viewing distance thanks to a newly developed flat lens. The system is an important step toward compact, realistic-looking 3D displays that could be used for televisions, portable electronics and table-top devices.
