One approach to treating cancer is photodynamic therapy using photo-uncaging systems, in which light is used to activate a cancer-fighting agent in situ at the tumor. However, suitable agents must be stable under visible light, have an anti-tumor effect in low-oxygen environments, and have the ability to be activated by low-energy tissue-penetrative red light – a combination of properties that is difficult to ...

A team of researchers from the UK and Russia have successfully demonstrated that a type of ‘magic dust’ which combines light and matter can be used to solve complex problems and could eventually surpass the capabilities of even the most powerful supercomputers. The researchers, from Cambridge, Southampton and Cardiff Universities in the UK and the Skolkovo Institute of Science and ...

A large long-term study found that breast cancer risk may be higher for women who live in areas with high levels of outdoor light at night. The link between outdoor light at night and breast cancer was found only among women who were premenopausal and were current or past smokers, and was stronger among those who worked night shifts. Women ...
