National parks preserve nature's splendor for our enjoyment, but they also contain some of the finest outdoor science labs in the world. In this issue, you'll get an up-close look at key research projects underway at 10 different parks around the United States. Could venomous creepy-crawlies hold the keys to potent, non-addictive painkillers? See why biochemist Glenn King is more than happy to work with dinner plate-sized tarantulas and deadly scorpions.  

Then, see how a doctor's gamble in the 19th century paved the way for a new cancer treatment. Speaking of chance, are top poker players and other gamblers skilled or simply lucky? And another burning question: Are aliens behind a star's crazy light patterns? You'll find answers to these questions and more inside the April issue of Discover.
