Biosignatures and structures in the geological record indicate that microbial life has inhabited
Earth for the past 3.5 billion years or so 1 , 2 . Research in the physical sciences has been …

The development of Thermoddem, a thermodynamic database devoted to geochemical
modelling for environmental studies in general and, more specifically, to chemical systems …

Modern yeast living in fleshy fruits rapidly convert sugars into bulk ethanol through pyruvate.
Pyruvate loses carbon dioxide to produce acetaldehyde, which is reduced by alcohol …

Uricase is an enzyme involved in purine catabolism and is found in all three domains of life.
Curiously, uricase is not functional in some organisms despite its role in converting highly …

The concept of storing radioactive waste in geological formations calls for large quantities of
concrete that will be in contact with the clay material of the engineered barriers as well as …

Features of the physical environment surrounding an ancestral organism can be inferred by
reconstructing sequences 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 of ancient proteins made by those …

We report a sequence reconstruction analysis targeting several Precambrian nodes in the
evolution of class-A β-lactamases and the preparation and experimental characterization of …

It is possible to travel back in time at the molecular level by reconstructing proteins from
extinct organisms. Here we report the reconstruction, based on sequence predicted by …

The chemistry of pore water is an important property of clayrocks being considered as host
rocks for long-term storage of radioactive waste. It may be difficult, if not impossible, to obtain …

Mineral carbonation is the single most eligible companion solution to geosequestration for
mitigation of anthropic CO 2 emissions on a large scale. Amongst its possible pathways, …
