Experimental taphonomy of Artemia reveals the role of endogenous microbes in mediating decay and fossilization
Exceptionally preserved fossils provide major insights into the evolutionary history of life. Microbial activity is thought to play a pivotal role in both the decay of organisms and the preservation of soft tissue in the fossil record, though this has been the subject of very little experimental investigation. To remedy this, we undertook an experimental study of the decay of the brine shrimp A...
متن کاملThe Functional Diversity of Epidermal Keratins Revealed by the Partial Rescue of the Keratin 14 Null Phenotype by Keratin 16
The type I epidermal keratins K14 and K16 are remarkably similar at the primary sequence level. While a structural function has been clearly defined for K14, we have proposed that a function of K16 may be to play a role in the process of keratinocyte activation that occurs after acute injury to stratified epithelia. To compare directly the functions of the two keratins we have targeted the expr...
متن کاملEmergent Fossilization
Aging is an inescapable fact of human life. In most areas of our lives, aging leads to an unremarkable, gradual decline in physical ability. For example, no one questions why a 40-year-old runner can no longer compete in the Olympics. As the body ages, metabolism slows, joints wear out, and energy is diminished. Aging also has a uniform natural effect on the learning of new skills. As a result,...
متن کاملEpiplakin attenuates experimental mouse liver injury by chaperoning keratin reorganization
BACKGROUND & AIMS Epiplakin is a member of the plakin protein family and exclusively expressed in epithelial tissues where it binds to keratins. Epiplakin-deficient (Eppk1(-/-)) mice displayed no obvious spontaneous phenotype, but their keratinocytes showed a faster keratin network breakdown in response to stress. The role of epiplakin in the stressed liver remained to be elucidated. METHODS ...
متن کاملFossilization: five central issues
Second language acquisition research over the past three decades has generated a wide spectrum of different interpretations of “fossilization” – a construct introduced by Selinker (1972) for characterizing lack of grammatical development in second language learning. These conceptual differences found in the literature, it has become increasingly clear, create confusion rather than offering clar...
