...particle accelerators last week and donned a molded plastic mask. At a signal, the accelerator beam was switched on, and nitrogen nuclei, traveling at almost the speed of light, flashed into his temple through a hole in the mask. At first nothing happened, even though the beam struck his optic nerve, behind the retina. For the next pulse, however, his head was moved so that the beam passed through his retina. "Hey, there's one!" he shouted. "Hey, there's a whole constellation...
...laureate and head of the Lawrence Berkeley Laboratory in California, had seen in his own lab the same flashes of light that astronauts see in space when their eyes are closed. Furthermore, he said, the experiment showed that atomic particles were causing the flashes -not through impact with the optic nerve or passage through the eye fluid, but by penetrating the retina itself...
...TIME Cinema Critic Stefan Kanfer-who has had a couple of his own TV and theatrical comedies produced -and edited by Peter Bird Martin. How did Martin and Kanfer feel about their all-women reporting team? Says Kanfer: "The work made its customary demands on the cerebrum, but the optic nerve had an easier time...
...seeing strange flashes of light in the darkened spacecraft, even though his eyes were closed. "I think I'm going out of my mind," Aldrin told Neil Armstrong. While Armstrong and other astronauts confirmed the mysterious flashes, NASA scientists were at first inclined to attribute them to an optical quirk. Now they have proposed a more plausible explanation: cosmic rays. Though only some of these high-speed particles-mostly protons-manage to break through the shield of the earth's magnetic field, they can easily penetrate the eyelids of a space traveler, pass through the eye fluid...
Most of Madden's own right eye was left in place, with its muscles, blood vessels and the all-important optic nerve, intact. What was transplanted was the cornea, with the iris and lens-roughly, the front third of the eyeball. Since the donor eye had been refrigerated and deprived of its blood supply before transplantation, there was little or no chance that it would give Madden any useful vision...
