POPSThe End of Aging - Still a Controvertial Vision Leon Kass and his friends are contemporary incarnations of an Orwellian nightmare. Besides "War is Peace", I hear also "Death is Life". Of course there are no known social good coming from the conquest of death, we never lived in a social system that conquered death. How could we possibly know? But Kass and his friends, seem to have some privileged knowledge we do not possess, and they already decided for us as individuals and as a society. Well, in time, I believe, they will have the choice to walk their talk. All I want is a chance to walk mine.

POPSHomosexual behavior due to genetics and environmental factors “Overall, genetics accounted for around 35 per cent of the differences between men in homosexual behavior and other individual-specific environmental factors (that is, not societal attitudes, family or parenting which are shared by twins) accounted for around 64 per cent. In other words, men become gay or straight because of different developmental pathways, not just one pathway.” For women, genetics explained roughly 18 per cent of the variation in same-sex behavior, non-shared environment roughly 64 per cent and shared factors, or the family environment, explained 16 per cent. The study shows that genetic influences are important but modest, and that non-shared environmental factors, which may include factors operating during fetal development, dominate.

POPSBaby to be born free of breast cancer after embryo screening This case of genetic intervention for the elimination of genetic diseases, is a ground breaking first that may change our world and our ethical outlook. Many more will follow. I was quite surprised to read the following: "Some critics say it is wrong to destroy embryos because there is only a chance women with the gene may develop breast cancer in adulthood. They argue that, increasingly, breast cancer can also be successfully treated. " The said "embryos" are 3 days old lumps of undifferentiated cells.

POPSDNA Study Unlocks Mystery To Diverse Traits In Dogs Dogs originally derived from the wolf more than 15,000 years ago -- a blink of the eye in evolutionary terms. Selective breeding produced dogs with physical and behavioral traits that were well suited to the needs or desires of their human owners, such as herding or hunting ability, coat color and body and skull shape and size. This resulted in the massive variance seen among the more than 350 distinct breeds that make up today's dog population. Until now, the genetic drivers of this diversity have intrigued scientists who have been trying to explain how and why the difference in physical and behavioral traits in dogs changed so rapidly from its wolf origins.

POPSScientists seek to create 'three-parent' babies "We respect the fact that there are people who have moral objections to any type of research involving human embryos. However, it could be argued that there is a moral obligation to reduce suffering in children at risk of inheriting mitochondrial disease," says Herbert.

POPSThe More We Know About Genes, the Less We Understand About 95 percent of the rewired bacteria did just fine with their new networks. They went on with their lives, feeding, growing and dividing. Some even performed better than microbes with the original wiring, under some conditions. The tolerance these bacteria showed reveals something important about how evolution works. Humans can randomly rewire cells, and so can mutations. There's something about gene networks that allow them to thrive despite these mutations, and, in some cases, to even gain an edge in the evolutionary race.
