The greening of Mars

TINY traces of organic dyes might be the best indicator of whether there was once life on Mars.

Such chemicals can last billions of years and would be a definitive sign that life thrived on the planet, …

At the start of each parliamentary session, the first 20 of these bills—proposed by MPs who don't hold a government post—are drawn from a hat, and if all goes well the first seven or so are likely to find the parliamentary time needed to …

Another "excellent" compilation she's got her teeth …

YUM! YUM! Feedback's stomach is aflutter at the thought of the latest innovation from the American fast-food industry.
