Some of the greatest advances in science have come from humanity's more destructive impulses. This is not the fault of science - when we discover powerful truths about the universe it's up to us to decide how to use them because they can either be boons or banes to the world. There may be no better example of this than the work done by the Manhattan Project - the years long, multinational effort to develop an atomic bomb during World War II. The project created unfathomably destructive weapons and led to a 50 year Cold War with the USSR, but is also the source of a lot of information about the atom we didn't have before, which has led to advances in many beneficial fields, like energy production and medicine. Science, like history, is always complicated.

Cicadas have developed an amazing strategy for growth, survival, reproduction, and overcoming predation by...doing nothing. They do nothing for years (except sip at the juice excreted from root structures) before emerging in huge, simultaneous swarms.
The swarm is so huge that predators can't consume even a fraction of it, but so rare that predator populations can't sustain themselves between emergence events. Clever little things!

Bitten by a venomous snake? There's hope! French scientist Albert Calmette developed the first snake antivenom in the late 1890s, and did such a good job that we use his technique to this day. Antivenom works by stimulating the production of antibodies which can smother venom's toxic effects, preventing spread and rendering them harmless. But how do you make it?

Earth had a climate long before we showed up and started noticing it and it's influenced by a whole series of cycles that have been churning along for hundreds of millions of years.

In the early days of the space race, agency researchers in Russia and at NASA really weren't sure all what would happen to an astronaut in space. They didn't know if a human mind could handle actually seeing Earth or what would happen to the human body when exposed to long periods of weightlessness. Would their blood forget which way to pump? Would their eyeballs shift or their inner ears wig out? They sent up mice and monkeys and dogs, to see what happened, and in 1961, the Russians strapped a man to a rocket headed for orbit.
