They're forever

DIAMONDS provide the most lasting evidence of ancient asteroid impacts, according to geologists in Germany. Falko Langenhorst of the University of Bayreuth and his colleagues have shown that the heat and pressure of an impact convert bits of buried coal or graphite into diamonds (Geology, vol 27, p 747). "The shape of impact diamonds is …

Regrettably, careless treatment regimes have encouraged drug-resistant strains of the bacillus to develop, which don't respond well to further treatment.

Feedback

THE FIRST terrestrial "life form" to escape from our Solar System may be a computer virus.
