SCFCyclin F-dependent degradation of CDC6 suppresses DNA re-replication

Nature Communications, 2016
To ensure genome stability, cells need to restrict DNA replication to once per cell cycle. Here the authors show that Cyclin F interacts with and targets the licensing factor CDC6 for degradation, preventing re-firing of replication origins.

Life Cycle Assessment of Coal-fired Power Production [PDF]

, 1999
Coal has the largest share of utility power generation in the US, accounting for approximately 56% of all utility-produced electricity (US DOE, 1998). Therefore, understanding the environmental implications of producing electricity from coal is an important component of any plan to reduce total emissions and resource consumption.
