LA JOLLA, CA—October 13, 2014—A new study by scientists from The Scripps Research Institute (TSRI), Lawrence Berkeley National Laboratory (Berkeley Lab) and other institutions suggests a cause of amyo...
Cascades of genetic instability resulting from compromised break-induced replication
Comparative Genomic Hybridization Break-induced Replication Copy Number Variations Chromosomal Rearrangements Double-strand Break Repair Half Crossover Homologous Recombination Non-reciprocal Translocation Half crossover instability cascades DNA double-strand break DNA repair Genetic instabilities Array-CGH

Break-induced replication (BIR) is a mechanism to repair double-strand breaks (DSBs) that possess only a single end that can find homology in the genome. This situation can result from the collapse of...
Dynamic instability of a growing adsorbed polymorphic filament

Abstract: The intermittent transition between slow growth and rapid shrinkage in polymeric assemblies is termed dynamic instability, a feature observed in a variety of biochemically distinct assemblie...
Dynamical membrane curvature instability controlled by intermonolayer friction
Dynamical membrane curvature intermonolayer friction phospholipid membrane

Abstract: We study a dynamical curvature instability caused by a local chemical modification of a phospholipid membrane. In our experiments, a basic solution is microinjected close to a giant unilamel...
Monodisperse domains by proteolytic control of the coarsening instability
Monodisperse domains proteolytic control the coarsening instability
2011/9/7
The coarsening instability typically disrupts steady-state cluster-size distributions. We show that degradation coupled to the cluster size, such as arising from biological proteolysis, leads to a nov...
