The caffeine is removed from green coffee beans, before they are roasted, and there are a number of different processes, all of which affect the roasting process and how long the coffee stays fresh. (Decaf coffee goes stale almost twice as fast as regular coffee.) The first decaffeination method, developed in the early 1900s, used a repetitive rinsing process aided by the chemical benzene, which is no longer used because it is a known cancer-causing agent.
Retina Display is a marketing term developed by Apple to refer to devices and monitors that have a resolution and pixel density so high â roughly 300 or more pixels per inch â that a person is unable to discern the individual pixels at a normal viewing distance.
High intensity visible light (such as staring directly at the sun for 10 minutes) damages the retina, causing a disease called solar retinopathy. In laboratory mice, bright light, especially blue, causes retinal damage. Therefore, it is likely that repeated exposure to bright visible light is damaging to the retina and may be a risk factor for age-related macular degeneration (AMD) and other retinal diseases.
