There are a few elements - especially platinum and palladium - that have the amazing ability to absorb up to 900 times their own volume in hydrogen gas. To get a sense of the scale there, that's roughly equivalent to a 250-pound man swallowing something the size of a dozen African bull elephants and not gaining an inch on his waistline.

Brains, you see, vary a lot from person to person - they vary as much as faces do. Sam Kean brainfacelot Change image and share on social
Something funny certainly happens when palladium and platinum come into contact with hydrogen gas; it's one of the great mysteries still waiting to be solved on the periodic table. But it's quite a leap from 'something funny' to cold fusion. Sam Kean coldcontactfunny share on social
Boron is carbon's neighbor on the periodic table, which means it can do a passable carbon impression and wriggle its way into the matrix of a diamond. But it has one fewer electron, so it can't quite form the same four perfect bonds. Sam Kean bondboroncarbon share on social
Most mutations involve typos: Something bumps a cell's elbow as it's copying DNA, and the wrong letter appears in a triplet - CAG becomes CCG. Sam Kean appearbumpcag Change image and share on social
All human beings are, in fact, born with dozens of mutations their parents lacked, and a few of those mutations could well be lethal if we didn't have two copies of every gene, so one can pick up the slack if the other malfunctions. Sam Kean bearbeingcopy share on social
Lithium makes a fine battery because it's a scarily reactive metal. Pure lithium ignites on contact if it touches water - a flake of it would sizzle and fry on the water-rich cells of your skin. Sam Kean batterycellcontact Change image and share on social
Although it's the hub of the nervous system and the ultimate terminus of every nerve, the brain itself lacks enervation and therefore cannot feel pain. Sam Kean brainenervationfeel Change image and share on social
