AA << results imply that multiple historical events during the transition from Mesozoic to Cenozoic eras, including the K-Pg mass extinction event, impacted the evolutionary dynamics in lichen-forming fungi. >>

<< We thought that lichens would be affected negatively, but in the three groups we looked at, they seized the chance and diversified rapidly, (..) Some lichens grow sophisticated 3D structures like plant leaves, and these ones filled the niches of plants that died out. >> Jen-Pang Huang.

<< Bacteria are rebelling >>
<< The germ, a fungus called Candida auris, preys on people with weakened immune systems, and it is quietly spreading across the globe. >>

<< The recent rate of emergence of pathogenic fungi that are resistant to the limited number of commonly used antifungal agents is unprecedented. The azoles, for example, are used not only for human and animal health care and crop protection but also in antifouling coatings and timber preservation. The ubiquity and multiple uses of azoles have hastened the independent evolution of resistance in many environments. One consequence is an increasing risk in human health care from naturally occurring opportunistic fungal pathogens that have acquired resistance to this broad class of chemicals. >>

Per nostra - di noi umani - fortuna oggi si puo' analizzare, studiare ed eventualmente manipolare in modo fine il codice genetico di virus, batteri, etc. grazie alla tecnica CRISPR, tecnica a suo tempo (e per molto tempo) considerata di nessuna importanza da entita' di alta- altissima luminescenza ...
