Why are people scared before an epidemic even happens?—A question inspired by the recent H1N1 outbreak. From a sociological perspective, entities that we rely upon to keep us safe from harm are now advising us that a threat is amongst us which is highly troubling to the human psyche. Aside from of our sense of safety being compromised, the usual suspects—media outlets and major public institutions, are also to blame for contributing to the present swine flu hysteria.
In a recent study (that yielded some exceptionally interesting results), catalytic RNA molecules were used in order to advance the understanding of Darwinian evolution. Researchers Dr. Sarah Voytek and Professor Gerald Joyce of the Scripps Research Kellogg School of Science and Technology, choose RNA molecules because they evolve rapidly and self-replicating RNA molecules are hypothesized to be the first organic “life forms” on earth. With a trillion molecules in a test tube replicating every few minutes, such an approach permits evolution to occur over the course of just a few days.
Molecular anthropology—you probably haven’t heard of this discipline by name but I guarantee that you already find this particular field fascinating. Therefore, I’d like to formally introduce to you the field of molecular anthropology which includes such areas of research as; genetically reconstructing man’s ancient migration from Africa to the Americas, resurrecting Neanderthal genomes and identifying ancestral origins through DNA ancestry.
Before the invention of boxed chocolates, Corvettes and bling-bling, all a man had to do for sweet lovin' was provide his special ladies with meat. Studies of extant hunter-gatherer societies show that literally bringing home the bacon leads to greater reproductive success. Highly skilled hunters also partake in more extra-marital affairs and in polygamous societies, have more wives.
In their Archives of Sexual Behavior publication, the stress hormone cortisol along with the dominance associated testosterone hormone was measured in 58 sadomasochistic practicing couples before and after kinky sex fun time.
Their results, along with a review of S&M literature suggests couples that practice S&M experience reduced levels of stress and feel an increase in relationship closeness.
Just imagine, all the cool and funky beats of rap music coupled with the wholesome words we use in science class. What a concept! And please, don't be hatin' on me because you didn't think of it first.
Unfortunately, scientists are far from curing this universal "disease" known as aging. However, understanding the mechanisms of aging will have a more immediate impact on the development of stem cell therapies, and researchers at the University of Gothenburg in Sweden have discovered that the female egg is capable of reversing this telomere molecular clock.
Weeds, trees or tomatoes; no matter the plant genome of interest, Yves Van de Peer and associate Bioinformaticians at the VIB-Ugent research institute repeatedly observe that the last genome duplication to have occurred in all extant plants happened at the same time—65 million years ago. This is a rather peculiar date considering it coincides with earth's last mass extinction event. With this factoid in mind, an inference can be made; duplicated chromosome mutants (polyploids) have a strong advantage during times of environmental hardship.
