[Mycological diagnosis: something is changing].

Great effort has been made in recent years to develop molecular techniques for laboratory diagnosis of mycosis. To this end, elucidation of the entire genomic sequence of the main fungal pathogens provides an unprecedented opportunity for clinical mycologists. There is considerable expectation regarding the potential application of the rapid advances in genomics and proteomics to study the molecular basis of fungal pathogenicity, to search for new and more effective antifungal drugs, and to identify fungal antigens.

How eukaryotic algae can adapt to the Spain's Rio Tinto: a neo-Darwinian proposal for rapid adaptation to an extremely hostile ecosystem.

Microalgae contributed 60% of the total biomass in the extremely hostile (pH 2 and metal-rich waters) environment of Rio Tinto (which is used as a model for the astrobiology of Mars). These algae are closely related to nonextreme lineages, suggesting that adaptation to Rio Tinto water (RTW) must occur rapidly. Fitness from both the microalga Dictyosphaerium chlorelloides and the cyanobacterium Microcystis aeruginosa was inhibited when they were cultured in RTW.
