Scientists used semiconducting crystals called quantum dots to measure temperatures inside living cells. Made of selenium and cadmium, the dots emit light of different wavelengths corresponding to temperature

Ultrasound equipment can be quite expensive, and those costs are often passed along to the patient. When my child was born two years ago, a single ultrasound session cost us over a thousand dollars! But

NASA is preparing to launch a medical breakthrough that could have dramatic implications for for terrestrial patients as well as astronauts. The NASA Biocapsule is made of carbon nanotubes, and implanted

A plasma is a state of matter (like solid, liquid and gas)in which ionized gases have high enough electrical conductivity that long-range electromagnetic fields dominate its behavior. A nanomaterial is

Researchers at Johannes Gutenberg University Mainz have developed a new way to visualize nano-structure and accurately resolve the position of atoms in a variety of substances. Scientists know that the

In the development of a successful regulatory strategy for nanotechnology, it is vital not to overlook the role of the military in the development and dissemination of potentially harmful nanotechnology
