When English chemist John Dalton first wrote about color blindness in 1798, he must have wondered how science would improve the quality of life for people living with the condition. Today, spectacles, ...

In the video, a preposterously cute, gray squirrel monkey named Dalton bonks his head against a computer screen in front of him. Wide-eyed and muttonchopped, Dalton has quite the setup—the screen, ...

For two squirrel monkeys nicknamed Dalton and Sam, life has gotten a lot more colorful. Researchers used gene therapy to correct the color blindness of the two adult monkeys, giving them the ability ...

Squirrel monkeys, which are naturally red-green color-blind, can attain humanlike color vision when injected with the gene for a human photoreceptor. The research, performed in adult animals, suggests ...

Genetic color-blindness may soon be a thing of the past. A team of scientists has used gene therapy to enable adult squirrel monkeys to see color for the first time, and they believe their technique ...

Monkeys once color-blind can now see the world in full color thanks to gene therapy. The results demonstrate the potential for such methods to eventually cure human vision disorders, from color ...

Scientists cast a rosy light on the potential for gene therapy to treat adult vision disorders involving cone cells -- the most important cells for vision in people. Scientists used gene therapy to ...

If nature gave you some bum genes, you've got a chance of fixing them. Genetic treatments have allowed researchers to cure color blindness in two squirrel monkeys. As published this month in Nature, ...
