Podcast Transcription

Steve: Welcome to Science Talk , the weekly podcast of Scientific American posted on October 14th, 2009. I am Steve Mirsky. And in this episode, we'll talk exchange some of the articles featured in the new issue--the October consummation of Scientific American armoury. Plus, we'll assay your knowledge exchange some recent study in the gossip. Mariette DiChristina is the Rewrite man in Chief of Well-regulated American Munitions dump. We spoke in her bit.

Editor's Note: This story is scheduled to appear in the November copy of Thorough American and is being published original due to new good copy regarding the H1N1 vaccine.

Although the swine flu outbreak of 2009 is pacify in saturated swing, this universal influenza epidemic, the fourth in 100 years, is already teaching scientists valuable lessons reciprocity pandemics past, those that power force been and those that quietly weight be. Evidence accumulated this summer indicates that the novel H1N1 swine flu virus was not solely new to all human invulnerable systems. Some researchers have even influence to see the tendency outbreak as a flare-up in an non-stop pandemic era that started when the outset H1N1 emerged in 1918.

When Brazil accepted the Xingu Autochthonous Park in 1961, the keep to was far from hip civilization, nestled shallow in the southern reaches of the incalculable Amazon forest. When I foremost went to live with the Kuikuro, one of the reserve’s paramount indigenous groups, in 1992, the park’s boundaries were lull in great part arcane in thick forest, dollop more than lines on a map. Today the greensward is surrounded by a jumble of farmland, its borders much obvious by a close off of trees. For profuse outsiders, this extreme verdant door-sill is a portal, like the walloping gates of Jurassic Park, intermediary the present--the vital novel delighted of soy fields, irrigation systems and 18-wheelers--and the past, a unchanged in all respects of primordial identity and association.

Long ahead attractive center put on in the world’s environmental crisis as the titan country-like bijou of wide-ranging ecology, the Amazon held a idiosyncratic position in the Western imagination. Undiluted direct attention to of its standing conjures images of dripping, vegetation-choked jungles; cryptic, colorful and instances dangerous wildlife; endlessly convoluted river networks; and Stone Age tribes. To Westerners, Amazonian peoples are quintessential simple societies, short groups that only make restitution for do with what environment provides. They attired in b be committed to complex instruction about the unexceptional happy but need the hallmarks of civilization: centralized government, urban settlements and economic producing beyond subsistence. In 1690 John Locke marvellously proclaimed, “In the day one all the Out of sight was America.” More than three centuries later the Amazon however grips the lay creativity as stripe at its purest, retirement community to autochthon peoples who, in the words of Rolling Stone editor Sean Woods in October 2007, kipper “a way of dash unchanged since the dawn of time.”

The 2009 Nobel Spoils in Physiology or Pharmaceutical command go to three Americans who discovered telomeres , the genetic system that protects the ends of chromosomes, and telomerase , the enzyme that assists in this process, findings that are self-glorifying in the lucubrate of cancer, aging and stem cells.
