Cell growth discovery has implications for targeting cancer Posted: 11 Oct 2013 07:11 AM PDT The way cells divide to form new cells — to support growth, to repair damaged tissues, or simply to maintain our healthy adult functioning — is controlled in previously unsuspected ways, researchers have discovered. The findings, they said, may lead to new ways to fight cancer.

New theory of synapse formation in the brain Posted: 10 Oct 2013 05:53 PM PDT The human brain keeps changing throughout a person's lifetime. Researchers have now been able to ascribe the formation of new neural networks in the visual cortex to a simple homeostatic rule. With this explanation, they also provide a new theory on the plasticity of the brain -- and a novel approach to understanding learning processes and treating brain injuries and diseases.

Researchers identify liver cancer progenitor cells before tumors become visible Posted: 10 Oct 2013 09:43 AM PDT For the first time, researchers have isolated and characterized the progenitor cells that eventually give rise to malignant hepatocellular carcinoma tumors – the most common form of liver cancer. The researchers found ways to identify and isolate the HCC progenitor cells long before actual tumors were apparent.
