Comment Re:Ask your optometrist (Score 1) 36

My (now ex) optomitrist tried pushing vitamins that were supposed to help repair retinal damage from blue light. I looked into them. They based their claims on a study done on mice which lacked the gene for macular repair. They exposed the mice to an intensity of blue light you'd expect to get if we had a blue sun and we lived on the sun facing surface of Mercury. Some of the mice showed macular damage with time. No kidding.

Comment Re:TIL There is an element called "Dysprosium" (Score 2) 27

When the global satallite system known as Iridium was in development, it had been named after the element with 77 protons which corresponded to the number of satallites in the system. Later changes to the system caused the number to go down to 66. Some of us joked that they should rename it Dysprosium, but marketing didn't like that quite as much.
