Dupuy et al., "Mammalian mutagenesis using a highly mobile somatic Sleeping Beauty transposon system," Nature, 436:221–6, July 14, 2005.This paper describes a modification of the Sleeping Beauty fish transposon which allows it to be used for efficient mutagenesis screens in mice. The authors provide proof-of-principle for the usefulness of t
Nature has once again beaten nanotechnology to the punch.
Human embryonic stem cells appear to accrue genomic changes that could make them unusable therapeutically when cultured at length.
California researchers have found a previously unrecognized role for microRNAs: aiding and abeting hepatitis C virus in the liver.
The debate continues as to whether telomerase's only function is to promote telomere extension.
Insect immunity may display hitherto unsuspected molecular complexity.

Lu et al., "MicroRNA expression profiles classify human cancers," Nature, 435:834–8, June 9, 2005.This article makes the surprising discovery that microRNA-expression profiles can be better predictors of cancer outcome than mRNA profiles. This conclusion is based on the use of a novel, bead-based flow-cytometry approach to examine the expressi
