A nurse uses a light therapy device to<br />

treat the side-effects of chemotherapy and<br />

radiotherapy in a cancer patient, during a<br />

trial at Birmingham Hospital in 2011 run<br />

by the University of Alabama. This High<br />

Emissivity Aluminiferous Luminescent<br />

Substrate (HEALS) technology uses 288<br />

powerful light-emitting diodes (LEDs) to<br />

provide intense light. HEALS light therapy<br />

was developed from experiments carried out<br />

at the International Space Station.<br />
