A transmissible cancer of soft-shell clams

A leukemia-like cancer is killing soft-shell clams along the east coast of North America. The cancer is transmitted between animals in the ocean, and appears to have originated in a single clam as recently as 40 years ago. Hemic neoplasm is a disease of marine bivalves that is characterized by proliferation of morphologically and functionally aberrant hemocytes, the …

Unexpected viral DNA in RNA virus-infected cells

Many years ago a claim was made that cells infected with respiratory syncytial virus contained infectious DNA copies of the viral genome. When this paper was published, retroviral reverse transcriptase had been discovered, which explained how DNA copies of retroviral RNA genomes were made in infected cells. Although the respiratory syncytial viral genome is RNA, it does …
