"The Genetic Response to Snowball Earth: Role of HSP90 in the Cambrian Explosion" Download this paper at the following web address: http://repositories.cdlib.org/postprints/2103 The events that shaped the Cambrian explosion from 545 to 530 Ma, when multicellular animals suddenly appeared in the fossil record, are not fully understood. It is likely that the evolution of new transcription factors and other signal transduction proteins that regulated developmental networks was important...

Knockouts are not just for Mice anymore. Aron Geurts and Howard Jacob from the Medical College of Wisconsin talk about their plans for creating transgenic rats using the Sleeping beauty transposon. Coming out of work pioneered by Colin Bishop's lab, Geurts and Jacob describe how the Sleeping Beauty system can be used to make transgenic rats and their plans to make the phenotype data from these rats available via the MCW PGA website ( http://pga.mcw.edu ) and the strains themselves accessible...
