Whenever you hear the word miracle, you know there's trouble just around the corner. But no matter many times they lead to disappointment or disaster, the newspapers never tire of promoting miracle cures, miracle crops, miracle fuels and miracle financial instruments. We have a limitless ability to disregard the laws of economics, biology and thermodynamics when we encounter a simple solution to complex problems. ... Biomass is...

One giant container ship can emit almost the same amount of cancer and asthma-causing chemicals as 50m cars. ... Confidential data from maritime industry insiders based on engine size and the quality of fuel typically used by ships and cars shows that just 15 of the world's biggest ships may now emit as much pollution as all the world's 760m cars.

Nuclear decay-driven machines could gather gases from the atmosphere of Mars, giving future robotic missions leaps of a kilometre, researchers say. A design concept in Proceedings of the Royal Society A outlines an approach to compress CO2 and liquefy it. The liquid would then be heated much as in a standard rocket, expanding violently into a gas to propel exploratory craft great distances.

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...
