As jets began flying higher and faster, the US Air Force became increasingly worried about the safety of its flight crew. Project Excelsior was initiated in 1958 to design a multi-stage parachute system that would allow a safe, controlled descent after a high-altitude ejection. In 1959 and 1960, Captain Joseph Kittinger made a series of high-altitude parachute jumps to test the new parachute system, setting three world records in the process. Who broke one of these records in 2012? Discuss

Antivenin is a biological material used to neutralize the venom of poisonous creatures like snakes, scorpions, spiders, and other insects. The antitoxins are created by injecting a small amount of venom into a serum-producing animal such as a horse, sheep, goat, or rabbit. The subject animal then suffers an immune response to the venom and produces antibodies which can be harvested from its blood and used to treat envenomation in others. What is mithridatism, and why is it so named?
