Washington, November 7: Duke University bioengineers say that gold nanostars may revolutionise medical diagnoses, and testing for environmental contaminants.

The researchers have revealed that their proposition is based on a comparison between all the shapes of nanoparticles studied to date, including rods, cones, cubes, and spheres.

They say that any such revolution would depend upon how light reflects off the particles, and nanostars can dramatically enhance the reflected light.

According to them, this increases their potential usefulness as a tracer, label, or contrast agent.

Washington, Nov 7: Scientists have found evidence that Beta-alanine (BA), a dietary supplement widely used by athletes and body builders, can boost fitness levels in older adults.

BA is an amino acid that, together with histidine, forms the dipeptide carnosine.

Carnosine is found in muscle tissue and makes an important contribution to the maintenance of intracellular pH, which is vital for normal muscle function during intense exercise. An increased intake of BA significantly raises muscle carnosine levels.
