Lithium tweaks many mood-altering chemicals in the brain, and its effects are complicated. Most interesting, lithium seems to reset the body’s circadian rhythm, its inner clock. In normal people, ambient conditions, especially the sun, dictate their humors and determine when… — Sam Kean Copy Share Image

Mendeleev, unlike the squeamish Meyer, had balls enough to predict that new elements would be dug up. Look harder, you chemists and geologists, he… — Sam Kean Copy Share Image
“Lithium regulates the proteins that control the body’s inner clock. This clock runs, oddly, on DNA, inside special neurons deep in the brain. Special… — Sam Kean Copy Share Image

“Think of the most fussy science teacher you ever had. The one who docked your grade if the sixth decimal place in your answer… — Sam Kean Copy Share Image
“For his part, Mendeleev scanned Lecoq de Boisbaudran’s data on gallium and told the experimentalist, with no justification, that he must have measured something… — Sam Kean Copy Share Image
“Sir Isaac Newton famously said that he had achieved everything by standing on the shoulders of giants—the scientific men whose findings he built upon.… — Sam Kean Copy Share Image
“If certain bacteria, fungi, or algae inch across something made of copper, they absorb copper atoms, which disrupt their metabolism (human cells are unaffected).… — Sam Kean Copy Share Image
“Scarily, cadmium is not even the worst poison among the elements. It sits above mercury, a neurotoxin. And to the right of mercury sit… — Sam Kean Copy Share Image
“Somehow, though, life turned that danger around, and this former poison became essential. It may sound trite, but this reversal always reminds me of… — Sam Kean Copy Share Image
