Mitochondria produce the majority of cellular ATP through oxidative phosphorylation, and their capacity to do so is influenced by many factors. Mitochondrial morphology is recently suggested as an important contributor in controlling mitochondrial bioenergetics. Mitochondria divide and fuse continuously, which is affected by environmental factors, including metabolic alterations. Underscoring i...

Abstract One reading of the Doctrine Original Sin has it that we are guilty a sin committed by Adam, thousands years ago. Fission theorists account for this saying Adam fissioned after he sinned and each us is one his ‘fission successors’. This paper recaps current discussion in literature about theory, arguing proposed version does not work reasons already raised Rea Hudson. I then introduce n...

It is a common procedure to describe the fission-fragment mass distributions of fissioning systems in the actinide region by a sum of at least 5 Gaussian curves, one for the symmetric component and a few additional ones, together with their complementary parts, for the asymmetric components. These components have been attributed to the influence of fragment shells, e.g. in the statistical sciss...

Recent years have placed fission yeast at the forefront of telomere research, as this organism combines a high level of conservation with human telomeres and precise genetic manipulability. Here we highlight some of the latest knowledge of fission yeast telomere maintenance and dysfunction, and illustrate how principles arising from fission yeast research are raising novel questions about telom...

During membrane fission, the GTPase dynamin forms helical assemblies at the neck of membrane buds. Although it has been proposed that fission results from the constriction of the dynamin helix, new work by Bashkirov et al. (2008) and Pucadyil and Schmid (2008) unexpectedly shows that helix disassembly is also necessary for membrane fission.

We report on a de novo centric fission of chromosome 11 in a healthy female referred for chromosome analysis due to recurrent miscarriages. Both fission products were mitotically stable. This centric fission of chromosome 11 appears to have no clinical significance for this patient other than recurrent miscarriages.

Experimental data on angular distributions of γ rays emitted from binary and ternary spontaneous fission of 252 Cf are analyzed. Their difference indicates that the alignment of fragments is higher in ternary fission than in binary one. The consequences of possible relation between the mechanism of ternary fission and the excitation of collective modes during the saddle-to-scission stage are di...

On the basis of the liquid drop model of atomic nuclei, an account is given of the mechanism of nuclear fission. In particular, conclusions are drawn regarding the variation from nucleus to nucleus of the critical energy required for fission, and regarding the dependence of fission cross section fo'r a given nucleus on energy of the exciting agency. A detailed discussion of the observations is ...

Following the early discovery of two-quasiparticle, high-K isomers in Fm (Z =100) and No (Z = 102) by Ghiorso et al. [1], a number of spectroscopic studies were carried out in the Fermium region, which have different sensitivities both in terms of decay branches (e.g. decay,  decay, fission, etc.) and lifetime ranges. There has been continuing activity in addressing the complex question of w...
