We could see in the dark some day. Researchers from China and the USA tested mice. Their tests let the mice see in the dark. The mice could see in the dark for about 10 weeks. The scientists said the tests did not damage the mice's eyes. The mice did not have any side effects.

Researchers want to do tests on humans. We have tried to develop new technology to give us extra abilities. This new technology could let someone see in the dark without needing night-vision goggles. We would not need to wear heavy technology. A researcher said the military might like this technology.
