The bad news is thatsometimes not all the cells are caught and the subsequent yearly monitoring thatmust follow causes patient anxiety and physical illness. Current monitoringmethods also carry a slight risk of accelerating tumor growth. ...... Dreyfuss and his colleagues have now answered two lingering questions: What is the SMN protein's normal function and how does decreased SMN protein activity cause degeneration of motor neurons? The team showed that the SMN protein is needed by all cells to produce messenger RNA (mRNA). Production of mRNA is a...Tipsheet From evidence of lingering DDT damage, to questions about artificial wetlands ashabitat, to the uses of a dynamic ecosystem evaluation and monitoring tool, USGSscientists will present a variety of wildlife research findings at the annualmeeting of The Wildlife Society at the B...
