¿Sabías qué? Los Estadios USACH y Municipal Bernardo O'Higgins de Quinta Normal en la capital chilena están separados por poco más de 700 metros en línea recta siendo los estadios más cercanos entre sí en el fútbol chileno #EstadiosDeChile

Busy morning at #Icy2024 where we showed our work ⁦@ibiochile⁩ on S. chiloensis (⁦@Tomas__P⁩’s work) and in paralell ⁦@lsaona⁩ on changes in fungal communities across Patagonia ⁦@LiliNucleo⁩ 😅😅 🌳🌳 Took some time to mention el Trauco and Caleuche!

Recientemente describimos una nueva especie de Saccharomyces aislada desde Chiloé denominada Saccharomyces chiloensis. Este descubrimiento es hoy noticia en La Tercera, y también en @estrellachiloe. Felices que sea compartido en su lugar de origen, Chiloé 😍 @Tomas__P

Even though we haven't detected phenotypic differences between southern S. eubayanus and S. uvarum Strains, S. chiloensis strains have a poor growth in maltose. Why? Something for the next work 🍻
