Variolation, Aviation, and Genetic Modification: Progress in the Face of Fear and Danger

In 1721, a small pox epidemic was ripping through the colonial city of Boston. Cotton Mather, a Reverend and Royal minister, convinced the physician Zebadiah Boylston to perform an arcane medical procedure on two slaves and Mather’s own son. The procedure, called “variolation,” involved piercing the skin of the patient with needle that was contaminated [...]

Flight 447 was also flying at a cruise altitude of 35,000 [...]

Flying ophidians! Physicists uncover how snakes soar between trees [Video]

flying snake glide physics

Some snakes don’t need to be on a plane to take flight. The "flying" snake (or paradise tree snake, Chrysopelea paradisi) launches its sleek frame into the ether from precipitously tall trees in Asia and sails downward. This seemingly strange behavior—particularly for an animal that has no limbs or skin flaps itself—has been long known, [...]
