An American woman, Frances H. Arnold, has won half of the 2018 Nobel Prize in chemistry, and George Smith of the U.S. and Sir Gregory Winter of the U.K. will share the other half.
Coloradans can get arrested for driving while stoned. But with no good roadside tools, officers' determinations are more subjective than for alcohol DUIs. Scientists hope to find chemical markers.
Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa share the 2016 Nobel Prize for Chemistry. By designing a tiny chain, axle and rotor blade, they made molecular machines a reality.
A refrigerator-sized machine could someday make lifesaving drugs on site when outbreaks occur or where medicine is in short supply, like on the battlefield.
He shared chemistry's top prize in 1996 for finding buckyballs, and had Lou Gehrig's disease when he died. Making art was his first love. "Remember your humanity," he said, "and forget the rest."
With the discoveries now confirmed, "The 7th period of the periodic table of elements is complete," according to the International Union of Pure and Applied Chemistry.
The "chemical hearth," dating back to the 1820s, was unearthed by workers doing renovations on the Rotunda at the University of Virginia. It is thought to be one of very few such labs still surviving.
Back in 2003, scientists were saying that hydrogen was the future -- that one day, we'd run all our cars on hydrogen, and be smog-free. But one UNLV scientist thinks that hype may have been premature. We find out why.
