NEW YORK (GenomeWeb News) – A team of scientists led by members of the British Antarctic Survey is using gene expression studies to uncover the genetic basis for a type of cold tolerance called cryoprotective dehydration.

The team developed cDNA microarrays to study gene expression in insects called Arctic springtails, or Megaphorura arctica, that had been dehydrated by cold or salt conditions or were recovering from such dehydration.
