"Molecules brought to Earth in meteorite strikes could potentially be converted into the building blocks of DNA, researchers have shown"

"Dr Clarke said: "We have demonstrated that the interstellar building blocks formaldehyde, acetaldehyde and glycolaldehyde can be converted in 'one-pot' to biologically relevant carbohydrates -- the ingredients for life.

"This research therefore outlines a plausible mechanism by which molecules present in interstellar space, brought to earth by meteorite strikes, could potentially be converted into 2-deoxy-D-ribose, a molecule vital for all living systems."

If you are interested in astrobiology there is a decent course on Coursera run by Prof. Charles Cockell from Edinburgh University. I did it a while ago. It is reasonably current but missing the very latest (like the Pluto mission).
