Synthetic fossilization of soft biological tissues and their shape-preserving transformation into silica or electron-conductive replicas
Structural preservation of complex biological systems from the subcellular to whole organism level in robust forms, enabling dissection and imaging while preserving 3D context, represents an enduring grand challenge in biology. Here we report a simple immersion method for structurally preserving intact organisms via conformal stabilization within silica. This self-limiting process, which we ref...
متن کاملSoft tissues
The deposition of amorphous calcium salts within the soft tissues is variously called mineralization or calcification. Two forms of calcium salts may be found in the soft tissues: calcium pyrophosphate dihydrate and calcium hydroxyapatite. If bony trabeculae are discernible within the mineralized focus the term ossification is used, sometimes prefixed with the terms ectopic or heterotopic. Ther...
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 کاملMorphogenesis of growing soft tissues.
Recently, much attention has been given to a noteworthy property of some soft tissues: their ability to grow. Many attempts have been made to model this behavior in biology, chemistry, and physics. Using the theory of finite elasticity, Rodriguez has postulated a multiplicative decomposition of the geometric deformation gradient into a growth-induced part and an elastic one needed to ensure com...
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...
