Dr. Emily Grossman explains even more of the world's most random, revolting and outright ridiculous science questions. Will sleeping with a cat on your head help get rid of dandruff? Do we really make better decisions if we need a wee? And, most importantly, how much of our DNA do we share with a banana? Covering a diverse range of key science topics, from human biology and animals and plants to the weather and space, Emily shows readers just how fun science can be.
