Blindness cause clue discovered

A team of scientists have discovered the enzyme which causes age related macular degeneration.
Macular degeneration is a form of age related blindness which affects many people as they get older. It occurs when the macula of the eye, which is responsible for the fine details in the centre of our vision, becomes diseased. International researchers have discovered an enzyme linked to the occurrence and progress of this disease which they hope will lead to a cure.
The researchers noticed the enzyme DICER1 was less active in the retina of people with the more common "dry form" of the illness and when they turned off the gene which makes the enzyme in mice, then the animal's retina cells were damaged.

Sweeeet. Damaging mice eyesight in the name of medical science. Nothing more human about that.

who cares about mice? my snake, that's about it. Hell if I could help by letting some scientist use my snakes food prior to him eating them, I'd be all for it to help blind people see.

Sweeeet. Damaging mice eyesight in the name of medical science. Nothing more human about that. My lab inflicts pain on rats and performs brain surgery on them to create new drugs that removes the feeling of pain. Rats are always used in medical research, unless you're ok with us testing on humans.

They should erect a huge statue to honor the sacrifices of the rat and the mouse.
