Summary

This week, we find out how to get useful gas from useless coal, and make money from waste carbon dioxide! Underground coal gasification could allow us to access huge amounts of energy in inaccessible coal seams. We find out how it works as well as exploring a new method for capturing waste carbon and turning it into useful chemicals. In the news, dinosaurs inspire new designs for aircraft, spotting a star being ripped apart by a black hole, and the South African bid for the world's biggest radio telescope. Plus, Diana asks what the point is of "junk" DNA? Like this podcast? Please help us by supporting the Naked Scientists

0:00.0	Stripping down science, the naked scientists.
0:07.0	The Naked Scientists. Hello, it's Sunday the 19th of June. Welcome to the naked scientists with me Ben Valzler and me Dave Ansel.
0:29.0	This week creating gas from coal and capturing carbon. We're exploring two technologies,
0:34.8	one that can make the most of an otherwise useless coal seam and another that can capture
0:39.2	carbon dioxide and turn it into useful products.
0:42.3	I investigate one of the most important historical uses of coal as a fuel for steam engines.
0:47.0	In the news, how dinosaurs inspire new designs for aircraft, designing unique chemistry, and spotting a star being ripped apart
0:56.2	by a black hole. Plus we'll be hearing about the South African bid for the square
1:00.5	kilometer array, the largest radio telescope that's ever been planned.

1:43.8	A unique astronomical event, an incredibly bright and long-lived burst of gamma rays,
1:49.0	was probably the result of a black hole destroying a star, according to research published in the journal Science this week.
1:56.0	On the 28th of March this year, NASA's swift satellite observed a bright flash of gamma rays emanating from a distant galaxy around 3.8 billion
