A ‘Magna Carta’ of sorts: In 1983, as AIDS hysteria swept across the nation, a group of advocates set out to remove the stigma of the illness and assert healthcare as a human right. At a gathering in Denver, they penned The Denver Principles that sparked a revolution. How did the manifesto serve as the “Magna Carta of AIDS activism”? And why are the words still so important 40 years later? (Above, people march during a Pride parade in 1983.)

Look, don’t touch: When you see a baby animal alone in the wild, your first instinct may be to approach it to help it. But as cute as it may be, your intervening may cause more harm than good. Like with white-tailed deer, mothers will leave their fawn (pictured above) alone, stashed in tall grass to avoid the attention of predators, while they forage for food.
