Scientists said on Thursday the bacterium, called Thiomargarita magnifica, is noteworthy not merely for its size - colossal for a single-celled organism at up to about eight-tenths of an inch (2 cm) long - but also because its internal architecture is unlike other bacteria.

Following is a summary of current science news briefs.

Tortoise and its egg found in latest Pompeii discovery
