The Permian extinction, described as 'the mother of all mass extinctions', saw 95 per cent of sea life wiped out, with 70 per cent of land animals killed. Scientists believe the discovery of layers of coal ash in rocks from the extinction boundary in Canada's High Arctic is the first direct proof that huge volcanic eruptions caused the extinction. ...read

Coming at you in 3D: Legendary filmmaker Werner Herzog brings paleolithic cave to life
The Chauvet-Pont-d’Arc Cave in southern France is the subject of a documentary by the German director called Cave Of Forgotten Dreams. Among the riches on offer below ground is a chamber full of painted monsters 400metres below the surface, where a mixture of carbon dioxide and radon gas leads to hallucinations. ...read

Is this the strangest plane ever developed by Nasa? The pivoting 'scissor' wing which doomed the AD-1 to stay grounded
Developed by Nasa in the 1970s, the AD-1 was a research aircraft designed to investigate the concept of a pivoting wing, which could be rotated on its centre pivot. It remained perpendicular to the fuselage during slow flight and swinging to angles of up to 60 degrees as aircraft speed increased. This allowed scientists to set it at the most efficient angle for the speed at which the plane was flying. ...read
PHOTOGRAPHY FLASHBACK
With modern cameras it's not just megapixels that matter - if you want an object of beauty for taking beautiful pictures, you need to go retro
Type: 10MP digital
Weight: 193g
Elegant, sturdy, compact and very serious, this high-end point-and-shoot is pricey but packs a hefty punch. Not only can it take low-noise 10MP stills, it can also capture 720p HD video.
5/5
Type: 10MP digital
Weight: 271g
The LX5 occupies the middle ground between the throwback romance of the Leica X1 and the elegant modernism of the Canon - and boasts the added cachet of the word 'Leica' on its 3.8x zoom lens. It's a versatile beast in a small package, as adept at taking a hi-def video clip as it is at capturing a razor-sharp landscape snap.
5/5
Type: 12.2MP digital
Weight: 286g
With no zoom, no video and a sluggish autofocus, it's a tad retro spec-wise too, but the DSLR-quality sensor and top-class lens can produce stunning results. They come at a price, though.
4/5
Type: 12MP digital
Weight: 131g
The H90 is pure Seventies, with its clean lines and block-like appearance. It doesn't do anything fancy on the performance front, but it's easy to use, compact and incredibly lightweight: one of the few cameras you can genuinely tuck into a jeans pocket.
3/5
Type: 35mm film
Weight: 214g
This has three tricks up its sleeve - first, the ability to shoot panoramic photos on normal 35mm film; second, a rewind knob that enables you to return to previous snaps and double-expose; and third, an option to shoot with visible sprocket holes.
4/5
Type: 35mm film
Weight: 134g
The embodiment of the phrase 'cheap and cheerful'. Inexpensive, plasticky and simple, the Diana Mini doesn't produce pixel-perfect digital pics - that's not the idea. Lomo cameras are prized by the hip for taking odd-looking, lo-fi snaps, with washed-out colours and light leakage.

Driving for three hours at night is 'as bad as being behind the wheel drunk'
The mother of all weather fronts: Great white storm over Saturn is half the size of Earth
Taken by Nasa's Cassini spacecraft, this incredible image shows a storm that, including the tail streaming off to the right, is more than 36,000 miles long. Storms shoot warm gas up from Saturn's lower atmosphere and through a thick upper mantle of old, smog-stained ammonia ice. As the gas expands in the upper atmosphere, fresh crystals of ammonia condense on the cooling vapour, forming the white region visible from Earth. ...read
