Scientists give mice night vision

It might be possible to see in the dark one day. Scientists gave mice the ability to see in the dark. Researchers from universities in China and the USA changed the vision in mice. They put special chemicals into their eyes. These let the mice see in the dark. The chemicals let the mice see in the dark for about 10 weeks. The scientists said the chemicals did not damage the mice's eyes. The mice did not suffer any side effects.

The research is in the journal 'Cell'. Researchers want to do tests on humans. Dr Tian Xue said: "Human beings have been trying to develop new technology to enable abilities that are beyond our natural abilities." He 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 said the military might like his research.
