Circadian clock and response to vaccination

Research in mice revealed that vaccination led to increased antigen-specific CD8+ T cell proliferation when administered mid-day. The circadian clock influences this response by controlling the cells' transcriptional program and modulating their responsiveness.

Renegade genes caught red handed

Researchers dispute the long-held belief that heterochromatin is a reliable guardian of the human genome. A study by University of Arizona researcher Keith Maggert reveals that heterochromatin can flicker on and off, allowing transposons to cause mutations and damage.
