Many different elements can form isomers, but only a few elements on the periodic table, like hafnium, can form isomers that last more than fractions of a second - and might therefore be turned into weapons. Sam Kean elementformfraction share on social
On a submicro scale, pure diamond is billions of billions of carbon atoms bonded to one another. If you shrunk yourself down and stood inside the diamond, you'd see nothing but carbon in a perfect pattern in every direction. Sam Kean atombillionbond share on social
Brain surgery couldn't happen without the patient's own active voice to guide the work. The patient is part of the surgical team here, perhaps the most important part, and above all, that's what makes neurosurgery different. Sam Kean activebrainguide share on social
Everywhere in the universe, the periodic table has the same basic structure. Even if an alien civilization's table weren't plotted out in the castle-with-turrets shape we humans favor, their spiral or pyramidal or whatever-shaped periodic table would naturally pause after 118 elements.

Mutations can arise anywhere in the genome, in gene DNA and noncoding DNA alike. But mutations to genes have bigger consequences: They can disable proteins and kill a creature. Sam Kean alikearisebig Change image and share on social

We know that genes shape human cultures and human societies: The DNA we inherited from our ancestors makes certain foods taste better, affects the way we care for children, influences what colors we find vibrant, and contributes to our love of socializing, among other examples.

As a child in the early 1980s, I tended to talk with things in my mouth - food, dentist's tubes, balloons that would fly away, whatever - and if no one else was around, I'd talk anyway. Sam Kean 1980sballoonchild Change image and share on social
Scientists didn't discover the noble gas helium - the second most common element in the universe - on Earth until 1895. And they thought it existed in minute quantities only, until miners found a huge underground cache in Kansas in 1903. Sam Kean cachecommondiscover share on social
Radium, discovered by Marie and Pierre Curie in 1898, was especially popular: the 'it' element of its day. Radium glows an eerie blue-green in the dark, giving off light for years without any apparent power source. People had never seen anything like it. Sam Kean apparentbluecurie share on social
