However, in a study reported in today's Circulation: Journal of theAmerican Heart Association, researchers did not find a causal relationshipbetween homocysteine and risk of heart disease.

...became resistant to fluorinated indolic compounds, suggesting that theEIR1 gene was helping yeast cells pump out the toxins. This suggests that EIR1functions as an efflux pump in roots, and because EIR1 is expressed only in theroots and not other parts of the plant, it suggests that the gene is responsiblefor t...Feed A Microbe An Unearthly Dish And You Make Your Own Extraterrestrial
