Mapping metabolism onto the prebiotic organic chemistry of hydrothermal vents.
Deep-sea hydrothermal vents provide a chemical interface between Earth’s reducing core and its oxidizing oceans. Today these environments support diverse chemosynthetic ecosystems (1), and after being discovered, they were soon proposed as the original site for the emergence of life (2). These hypotheses have considerable appeal but have not been universally accepted, partly because many aspect...

متن کاملAre hydrothermal vents oases for parasitic protists?
mosquitoes is well known. As Hoffman and Miller comment, ‘We suggest a combination of directed wind and volatile repellent might be developed as a mosquito deterrent strategy for the backyard setting’ [3]. Indeed, the combination of DEET and permethrin in a coconut base (Mosbar) as a malaria control measure looks promising (M. Rowlands et al., unpublished). Volatile oils from plants can serve a...
متن کاملRemoval of Chelated Copper by TiO2 Photocatalysis: Synergetic Mechanism Between Cu (II) and Organic Ligands
UV/TiO2 photocatalysis of chelated copper in aqueous solutions has been performed starting from Cu(II)-tartaric acid, Cu(II)-citric acid, Cu(II)-EDTA and Cu(II)-DTPA,in the presence of oxygen and at acidic pH. The photocatalytic reaction obeys first-order kinetic equation. The influence of Cu(II) on photocatalytic oxidation of organic ligands and how the various organics will affe...
