A radical proposal for how a tiny organism can transform our understanding of human relations Serving as both a guide and companion publication to the conceptual art project of the same name The Lichen Museum explores how the physiological characteristics of lichens provide a valuable template for reimagining human relations in an age of ecological and social precarity Channeling between the personal the scientific the philosophical and the poetic A Laurie Palmer employs a cross disciplinary framework that artfully mirrors the collective relations of lichens imploring us to envision alternative ways of living based on interdependence rather than individualism and competition Lichens are composite organisms made up of a fungus and an alga or cyanobacteria thriving in a mutually beneficial relationship The Lichen Museum looks to these complex organisms remarkable for their symbiosis diversity longevity and adaptability as models for relations rooted in collaboration and nonhierarchical structures In their resistance to fast paced growth and commodification lichens also offer possibilities for humans to reconfigure their relationship to time and attention outside of the accelerated pace of capitalist accumulation Drawing together a diverse set of voices

El uso de técnicas de ingeniería genética permite combinar genes de distinta procedencia, amplificarlos y transferirlos de un ser a otro, rompiendo la barrera de las especies como unidades genéticamente inmiscibles. Los avances en la produccion de animales transgenicos y clonicos revolucionan las industrias asociadas y preocupan a nuestra sociedad. Lo que en genetica parecia imposible hace 30 años: el analisis in vivo de la funcion de los genes, la sintesis a gran escala de sus productos de expresion, el estudio de genomas complejos, etc., se aborda hoy en laboratorios modestos de genetica y biologia molecular.Las tecnicas de ingenieria genetica y la transferencia de genes contribuyen constantemente al avance de nuestro conocimiento sobre los mecanismos basicos que operan en celulas, tejidos y organos durante el desarrollo embrionario. Sus aplicaciones practicas estan destinadas a mejorar nuestra calidad de vida y la de los paises mas desfavorecidos ?por ejemplo, las plantas transgenicas pueden producir plasticos biodegradables o vacunas contra la gastroenteritis.El objetivo principal de este libro es explicar la base conceptual de este conjunto de tecnicas y dar a conocer sus aplicaciones mas inmediatas. La exposicion es clara, concisa y amena para que el lector, alumno o profesional interesado progrese en el conocimiento y sea capaz de valorar tanto su versatilidad como su utilidad.
