, they look like something out of a 1950s B-movie. Colonies of fossilised creatures, dubbed “hairy blobs”, have been discovered in one of the harshest environments on Earth. The find may turn out to be crucial for spotting signs of extraterrestrial life in rocks on other planets

Call it extraterrestrial bling. Fossilised sea creatures have been found that coated themselves in tiny diamonds created in the asteroid impact that killed off the dinosaurs.

Life’s a beach on planet Earth
Did life on Earth begin on a radioactive beach? That’s the claim of one astrobiologist, who says that life’s ingredients could have emerged from the radioactive sand grains of a primordial beach laced with heavy metals and pounded by powerful tides.
On Saturday a phoenix ascended to the heavens upon a pillar of fire and smoke, rising from the ashes of its ancestors.

Nanotechnology has invaded the fuel tank. But forget Prince Charles’s “grey goo” and science fiction tales of rampaging swarms of nano-robots. This invader is a harmless diesel fuel additive, and just a teaspoon in your tank can not only increase your fuel economy by up to 10 per cent, but significantly cut harmful exhaust emissions.

Dr Who’s TARDIS may not have been quite so far-fetched an idea after all. A canister filled with new ‘nanocubes’ is able to hold several times more gas than an empty one. These crystals were developed by scientists working for chemical giant BASF, and are fantastically porous. Just a thimbleful has the surface area of a football pitch. What’s more, they are formed in a reaction so simple it could be done in a school chemistry lab. The crystals represent part of the company’s commitment to the emerging field of nanotechnology – materials on the scale of a billionth of a meter. In the case of their nanocubes, it is only the pores that are nano-scale – the crystals themselves are the size of salt grains.

Cuttlefish have an extraordinary, and almost instantaneous, control over their appearance. They can produce hundreds of distinct patterns, which they use for camouflaging, courting mates or startling predators. One dynamic pattern, where thick black and white bands flow rapidly over the skin of the cuttlefish as it near its prey, is somewhat of a mystery. Why, just as the cuttlefish approaches an unsuspecting target, should it switch from camouflage to a highly conspicuous display?
