Do you want to see in the dark? This might be possible. Scientists gave mice the ability to see near-infrared light. This is a kind of light that mice cannot usually see. Researchers from universities in China and the USA changed the vision of the mice they tested. They injected special nanoparticles into their eyes. These nanoparticles let the mice see better in the dark. The injections meant the mice could see in the dark for about 10 weeks. The scientists said the injections did not damage the eyesight of the mice. The eyes of the mice did not suffer from any side effects.
The research is published in the journal 'Cell'. The researchers hope their tests could be done on humans. Researcher Dr Tian Xue said: "Human beings have been trying to develop new technology to enable abilities that are beyond our natural abilities." He said tests in the future could let humans see in the dark. Dr Tian added: "Another cool thing about this potential technology is that it wouldn't require a person to wear heavy and energy-intensive equipment, such as night-vision goggles." He also said the military might be interested in his research.
