EnginEEring and natural SciEncES Should Extinction Be Forever
Typically the extinction of a species is thought of as an ultimate end by conservation biologists. However, now with the advent of inter-species somatic cell nuclear transfer extinct species can be re-created using a tissue sample from the extinct species and oocytes from a related species. This technology has a long way to go before stable populations of previously extinct species can be creat...
متن کاملIs extinction forever?
Mistrust of science has seeped into public perception of the most fundamental aspect of conservation-extinction. The term ought to be straightforward, and yet, there is a disconnect between scientific discussion and public views. This is not a mere semantic issue, rather one of communication. Within a population dynamics context, we say that a species went locally extinct, later to document its...
متن کاملI-14: Assisted Reproduction and Religion What Consideration Should Be and Should Not Be Relevant,
Several important issues are pertinent to an ethical discussion of the new technology today grouped under the name Assisted Reproduction Technology (ART). This is a moral imperative because each of us must decide what is to be considered ethically acceptable in assisted reproduction. Reflecting on the ethical dimension of ‘creating’ a new human life can play a major role in ensuring that in eac...
متن کاملExtinction rates should not be estimated from molecular phylogenies.
Molecular phylogenies contain information about the tempo and mode of species diversification through time. Because extinction leaves a characteristic signature in the shape of molecular phylogenetic trees, many studies have used data from extant taxa only to infer extinction rates. This is a promising approach for the large number of taxa for which extinction rates cannot be estimated from the...
متن کاملStaphylococcus lugdunensis; a pathogen that should be considered in Iran
Background: Staphylococcus lugdunensis is Gram-positive cocci of the staphylococcaceae family. S. lugdunensis despite having a clotting factor (wall coagulase), was classified in the coagulase negative staphylococcus group (CoNS) for lack of free coagulase. Although this bacterium is part of the human normal flora, in terms of virulence, S. lugdunensis is in second place after S. aureus. S. lug...
