The body can make all the cholesterol it needs, but Americans tend to have a surplus, thanks in large part to too little exercise and too much meat, cheese and grease. Fifty years ago, researchers...

Ice is a good insulator, says Steven Desch, a planetary scientist at Arizona State University in Tempe. That’s why moons such as Jupiter’s Europa and Saturn’s Enceladus, among others, may be able to maintain liquid oceans beneath their...
