Researchers compare neurons in optic nerves to find why some regenerate and others don't
It's a question that seems to offer tantalizing hope to those suffering from vision impairment. Why is it that when the optic nerve is damaged—either through trauma or disease—few of its neurons survive and fewer still ...

Narrow subset of cells is responsible for metastasis in multiple myeloma, study finds
Although it is among the most highly metastatic of all cancers, multiple myeloma is driven to spread by only a subset of the myeloma cells within a patient's body, researchers at Dana-Farber Cancer Institute have found in ...
