Oil dispersants can suppress natural oil-degrading microorganisms, new study shows

A new study led by University of Georgia marine scientists found that oil dispersants can suppress natural oil-degrading microorganisms, promoting the growth of Colwellia and inhibiting Marinobacter. The presence of dispersants significantly altered microbial composition in Gulf deep water, hindering efficient oil biodegradation.

Strangled cells condense their DNA

A recent study has shown that when cells are deprived of oxygen and nutrients, their DNA becomes compacted into tight clusters. This dramatic change reduces gene activity and leads to cell shutdown. The discovery may help researchers develop new treatments for diseases such as heart attacks, strokes, and cancer.
