【科学60秒】 诺奖得主对抗黄斑退化症
听力简介：
请填写这句话，不用写引号。
Macular degeneration causes visual distortion and even complete loss of sight. When the wife of chemistry Nobel laureate Walter Kohn was diagnosed with macular degeneration, he wanted to do something. I spoke with him at the recent Lindau Nobel Laureate meeting in Germany.
“______（请填一句。）________ ”
A macular degeneration patient looks at a completely regular grid on a computer screen. But because of the condition, the grid will appear distorted. The patient uses a mouse to adjust the grid to appear normal.
“We will receive from the patient an edited piece of graph paper. And from the way the patient edits it, we can tell what the distortions are that he perceives and from these we can then develop devices that correct his distortions.”
