Once upon a time there was the Big Bang theory of the origins of the universe. Now, you could say, we have another, more local, "big bang" – for the origin of life on Earth. According to scientists in Arizona, the crucial components necessary for life to start may not have been generated by our own planet in the first instance, but come from somewhere deep in outer space, carried by the barrage of meteorites that crashed into the earth four billion years ago. The key is the discovery that a meteorite was capable of providing nitrogen-containing ammonia.

Brian Marsden: Astronomer who played a central role in Pluto's downgrading to dwarf-planet status

The British-born astronomer Brian Marsden, Emeritus Director of the Minor Planet Centre (MPC), once famously – but wrongly – warned of an asteroid collision with Earth. He also helped demote Pluto to "dwarf planet" status and accurately predicted the return of Comet Swift-Tuttle.

Last Night's TV: Wallace and Gromit's World of Invention/BBC1<br />Horizon: Asteroids &ndash; the Good, the Bad and the Ugly/BBC2

I don't mean to be harsh, but I think Wallace's future as a television presenter is limited, despite the fact that he appears to have his own television studio in the basement. It isn't just that he has a face for radio – with his chiclet teeth and his permanently astonished gaze – but there's also the question of his reaction times. He can appear spontaneous, it's true, but it takes a team of three people working for a fortnight to make him so, which is always going to make things tricky when it comes to topical content. Hardly surprising, then, that in Wallace and Gromit's World of Invention he's only supplying fairly minimal links to filmed reports – heavy on the bad puns and relatively light on the elaborate ingenuity which fans have come to associate with one of Aardman's leading stars. If you were hoping for 30 minutes of animation you will have been disappointed, because Wallace and Gromit are here only as a kind of novelty wrapping paper for the sort of technological curiosity that would have once filled out the lighter stretches of Tomorrow's World.

Amol Rajan: Let the axe fall on stale metaphors

This week, what passes for political debate in this country has, according to its protagonists, been a "soap opera" between "old", "new" and "next" Labour. Last week, everything hinged on whether or not the Coalition's Budget was "progressive". A few weeks earlier, acres of newsprint addressed our Prime Minister's use of the phrase "middle class". Nobody knows what any of these terms mean, least of all those who initially submitted them for public consideration. "Progressive" is related somehow to protecting the poor; "middle class" is so abused and polysemous as to be nothing more than a badge of honour among the unthinking rich. Our political language is not in a good state.

Errors & Omissions: It may be hypothetical, but it's still completely wrong

"Begging the question" is one of the permanent fixtures of pedantry. We are forever pointing out that very few people know what "beg the question" means. When people use it they invariably mean "raise the question".
