'Domesticated' gene may have helped originate placenta in mammals

Model points to importance of polymerase activity in species jump

RNA interference (RNAi) takes place in the nuclei of human cells, according to a group from the University of Massachusetts Medical School.

US group says RNA interference takes place in the nucleus, but one expert is unconvinced

By exploiting a malaria parasite's "Achilles heel," researchers in Germany say a transgenic whole-organism vaccine for humans may be possible.

Study shows promise for 'ecological' approach, but other researchers raise questions

Mouse needs G-protein-coupled receptor to keep its eggs fresh, according to study

Genetically modified parasite induces immunity in rodents, but some doubt use in humans

Findings on Fugu gene splicing could help scientists develop pufferfish transgenes for mammalian cells, say researchers at Massachusetts Institute of Technology.

Cell line study shows miR-375 regulates the late stages of insulin secretion

Study uncovers mechanism of histone monoubiquitylation and gene silencing

Understanding how mammal splicing enhancers differ from fish makes Fugu more useful
