Phenolic compounds are an extremely diverse class of ubiquitous secondary metabolites produced by a variety of organisms playing different biological roles. They have numerous types of demonstrated bioactivities, including antioxidant, antimicrobial, anti-inflammatory, antitumoral, immunomodulator, neuroprotective, cardioprotective, and antidiabetic activities. Marine organisms produce a vast collection of unique phenolic structures, some of them not found in terrestrial habitats. Progress in different aspects is rapidly advancing, and this Special Issue will provide updated information and recent studies on marine phenolics. Specially, this issue is focused on their chemical characterization, elucidation of their structures, evaluation of their biological properties and mechanisms of action, efficient extraction and purification technologies, development of value-added applications, as well as formulation of novel products.

Increasingly, young people live online, with the vast majority of their social and cultural interactions conducted through means other than face-to-face conversation. How does this transition impact the ways in which young migrants understand, negotiate, and perform identity? That's the question taken up by Digital Passages: Migrant Youth 2.0, a groundbreaking analysis of the ways that youth culture online interacts with issues of diaspora, gender, and belonging. Drawing on surveys, in-depth interviews, and ethnography, Koen Leurs builds an interdisciplinary portrait of online youth culture and the spaces it opens up for migrant youth to negotiate power relations and to promote intercultural understanding.
