This ridiculous rhinestone-studded disco-ball is actually a high-precision laser-reflecting satellite still in orbit around the Earth. With only tiny reflectors and no active instruments, it’s provided vital data on the planet’s shape for decades.

FOUND: A GENE THAT PREVENTS ELEPHANTS FROM GETTING CANCER

Logically, elephants should get cancer much more than humans do—elephants have 100 times more cells than we do and live just about as long, providing ample opportunity for cancer-causing mutations to occur. But in fact they have less cancer; an analysis of hundreds of zoo deaths found that only five percent of elephants die of cancer, whereas 11 to 25 percent of humans do, according to the New York Times. Scientists hypothesize that, in order to get so large and biologically complex, elephants’ bodes must have evolved a way to suppress cancer. But they weren’t sure quite how they kept the cancer at bay.
