'Normal' Cells Far From Cancer Give Nanosignals Of Trouble
July 11, 2009 — A new study of human colon, pancreatic and lung cells is the first to report that cancer cells and their non-cancerous cell neighbors, although quite different under the microscope, share very ... > full story -
Stem Cells' 'Suspended' State Preserved By Key Step, Scientists Report
July 10, 2009 — Scientists have identified a gene that is essential for embryonic stem cells to maintain their all-purpose, pluripotent state. Exploiting the finding may lead to a greater understanding of how cells ... > full story -
Bacterial Quorum Sensing: A Matter Of Density, Not Quantity
July 10, 2009 — Researchers have demonstrated that the absolute number of cells is irrelevant to the process of bacterial quorum sensing; only the number of bacteria in a given volume plays a role. They were even ... > full story -
MicroRNAs Help Control HIV Life Cycle
July 9, 2009 — Scientists have discovered that specific microRNAs (non-coding RNAs that interfere with gene expression) reduce HIV replication and infectivity in human T-cells. In particular, miR29 plays a key role ... > full story -
