Fuel cells need a catalyst to speed up the chemical reactions that change hydrogen into water and electricity. Platinum is very good at this but it is famously expensive and rare. Some microbes, though, have known for a billion years how to make enzymes that can do the job using cheap and abundant nickel and iron. These natural enzymes are unfortunately difficult to obtain and do not do so well outside the microbe. Now researchers have...

A study using the Herschel space telescope aimed to measure the fraction of deuterium, a rare type of hydrogen, present in the comet's water. Like our oceans, it had half the amount of deuterium seen from other comets. The result, published in Nature, hints at the idea that much of the Earth's water could have initially come from cometary impacts.
