A natural mechanism for l-homochiralization of prebiotic aminoacids
We propose a mechanism that explains in a simple and natural form the l-homochiralization of prebiotic aminoacids in a volume of water where a geothermal gradient exists.

Some considerations about snow crystallogenesis
We investigate about the possibility of knowing the thermal history of each snow crystal through the analysis of its individual habitus. Supposition, based on experimental observations, that prevailing growth mechanisms of basal and prismatic surfaces are helicoidal and 2D nucleation-spread, respectively, make possible to establish the relation temperature-habitus for all the different kinds of crystals, with the exception of plates in the interval -3^\circ C < T < 0^\circ C, where probably the surface melting plays an important role on the habitus development.
