Cool trick

PARASITIC wasps siphon off antifreeze from their fly hosts to protect them from chilly winters—a discovery which could improve biological control of pest flies.

For 15 years, the company has avoided court action at home for the world's worst industrial accident. The reason's obvious: if a US court …
