“A summary of taxonomic and phylogenetic studies of saprobic microfungi collected in southern United States is presented. One novel genus and two species of asexual Ascomycota were described new to science from the southwestern states of Arizona and New Mexico.”

“A scale separation between the space-time’s and the internal dimensions’s degrees of freedom can be obtained by adjusting the parameters of the string geometry. We describe this scale hierarchy and the cosmological evolution of the scalar fields for type IIB string theory on the geometry of the mirror quintic.”

“We study novel non-Abelian dualities between gauged linear sigma models, which constitute an ultraviolet description of string theory. These dualities can lead to new physical symmetries between different geometries.”

“Back during my time at the Universidad Tecnológica de La Habana “Jose Antonio Echeverrı́a”, CUJAE I assist with a workshop on the Problem Base Learning (PBL) approach to teaching. Little did I know about the serious science behind the development of innovative Learning and Teaching approaches. Even less on how far in our history, it is possible to track our “modern” problems and solutions! In the present contribution I share with the readers some of these findings. I will particularly focus on those corresponding to the Hellenistic times of the classical Greco-Roman philosophy, and hopefully, just hopefully, I will be able to transmit how modern these “ancient thoughts” look like.”
