Oiling Up

Cell cycle: Oiling the gears of anaphase

The anaphase-promoting complex (APC) or cyclosome directs the ubiquitination and destruction of proteins that control specific steps in mitosis. Recent studies show that APC activity requires WD40 domain proteins, and that one of these proteins is part of the checkpoint control that ensures accurate chromosome segregation.

Even light oiling from spills can be catastrophic for birds.

It’s a depressingly familiar sight when an oil well blows or a tanker runs aground: thousands of stranded, helpless animals wallowing in cloying crude oil. ‘Birds are often used as the poster children for the deadly effects of oil’, says Ivan Maggini from Western University, Canada, recalling the shocking images of struggling animals that accompanied the catastrophic Deepwater Horizon oil spill...

Oiling accelerates loss of salt marshes, southeastern Louisiana

The 2010 BP Deepwater Horizon (DWH) oil spill damaged thousands of km2 of intertidal marsh along shorelines that had been experiencing elevated rates of erosion for decades. Yet, the contribution of marsh oiling to landscape-scale degradation and subsequent land loss has been difficult to quantify. Here, we applied advanced remote sensing techniques to map changes in marsh land cover and open w...
