Mitochondrial oxidative phosphorylation is programmed to set and maintain metabolic homeostasis. This is accomplished through an intrinsic program that determines the metabolic [ATP]/[ADP]/[Pi], where [Pi] is the concentration of inorganic phosphate (energy state) and maintains it through a bidirectional sensory/signaling control network that reaches every aspect of cellular metabolism. The pro...

For generations programmed mammal aging was widely thought to be theoretically impossible. However, new evolutionary mechanics concepts have led to renewed interest in programmed aging resulting in a schism between programmed and non-programmed proponents. This article argues that this lack of consensus is damaging medical research and therefore steps should be taken to pro-actively resolve the...

This new journal, which replaces the Bulletin of the Association for Program , Learning, pledges itself to "stress a systematically empirical approach and take the lifle. t; programming is essentially an experimental procedure.'' It also promises "to commit11 to a readership which includes many practising teachers . . ^ The first issue fulfils both of these laudable objectives. It includes info...

Plants often respond to pathogens by sacrificing cells at the infection site. This type of programmed cell death is mimicked by the constitutive pathogene response5 (cpr5) mutant in Arabidopsis in the absence of pathogens, suggesting a role for CPR5 in programmed cell death control. The analysis of the cellular phenotypes of two T-DNA-tagged cpr5 alleles revealed an additional role for CPR5 in ...

The traditional way of achieving different grain particle sizes in hammer mills is by manually changing the screen to desired size. This manual process a production procedure that time-consuming, demanding, and resource-draining. study incorporated identification speed control mechanism into mill machine. detection system recognizes type through an RGB (Red, Green, Blue) colour sensor. has been...

Current use of microbes for metabolic engineering suffers from loss of metabolic output due to natural selection. Rather than combat the evolution of bacterial populations, we chose to embrace what makes biological engineering unique among engineering fields - evolving materials. We harnessed bacteria to compute solutions to the biological problem of metabolic pathway optimization. Our approach...
