Accelerated evolution converts RNA enzyme to DNA enzyme in vitro
This 'evolutionary conversion' provides a modern-day snapshot of how life as we understand it may have first evolved out of the earliest primordial mix of RNA-like molecules-sometimes referred to as the "pre-RNA world"-into a more complex form of RNA-based life (or the "RNA world") and eventually to cellular life based on DNA... view more...

Hormone might cause dangerous pregnancy complication
Researchers at the University of Cincinnati (UC) Academic Health Center have found evidence of a hormone they say is responsible for certain types of high blood pressure (hypertension), and could also cause preeclampsia, a potentially dangerous condition that occurs during pregnancy.   view more (2005-10-18)

Active ingredient in common Chinese herb shown to reduce hypertension
Some 50 million Americans have hypertension, that is, blood pressure measuring above the normal range (less than 120/80 mmHg). If untreated, it can lead to heart attacks, strokes, or kidney disease. Lifestyle changes are the first-stage treatment for the disease, but if they fail, medications are prescribed.   view more (2007-01-19)

All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon species. In the June issue of Ecology Letters, Smith... view more... (2003-05-22)
