Would you like to be able to see in dark? One day this might be possible. Scientists have done tests on mice and have given them ability to see near-infrared light. This is kind of light wave that mice (and humans) cannot normally see. Research teams from University of Science and Technology of China and University of Massachusetts Medical School changed vision of the test mice. They injected special nanoparticles into their eyes. These tiny particles let mice see better in the dark. The effect of injections lasted for around 10 weeks. The scientists said the eyesight of mice was not damaged and eyes did not suffer from any side effects.

research is now published in research journal 'Cell'. The researchers say they hope the same tests could be done with humans. Researcher Dr Tian Xue explained what he hopes for future. He said: "Human beings have been trying to develop new technology to enable abilities that are beyond our natural abilities." He said future tests could let humans see things in dark that they cannot see now. Dr Tian added: "Another cool thing about this potential technology is that it wouldn't require person to wear heavy and energy-intensive equipment, such as night-vision goggles." He also said: " military will very likely be interested in this work.
