  • Improving rice yields under drought--Part 1 Researchers at the International Rice Research Institute (IRRI; htp://irri,org ) are working to improve rice yields under drought. This is necessary for sustainable rice production in rainfed areas. The conventional breeding approach that revolve around using improved donors and direct selection for grain yield under drought in early segregating generations has resulted into development of high yielding lines with good level of drought tolerance. Molecular approaches to improve yield under drought revolve around identification and introgression of major Quantitative Trait Loci (QTLs) for grain yield under drought. In this video, Arvind Kumar, senior IRRI breeder specializing in drought tolerance, shows what the varieties being tested look like with plenty of water to participants of the annual meeting of the Hybrid Rice Development Consortium (HRDC) held at IRRI on 22 March 2011.
  • Egypt's Sumerian Revelation The Late Predynastic in Egypt falls within the Uruk Period of Mesopotamia 4000-3200BC However, earlier penetration of Caucasoids into North Africa has occurred over the millennia. This video discusses Egypt's archaeological relations With Eurasia/Fertile Crescent/Levant of the predynastic leading up to the dynastic period of Egyptian history. If Egyptians were negroids that originate from Sub Saharan Africa - as Afrocentrics proclaim, there should be massive amounts of Sub Saharan "data" in the archaeological record. Instead what we have discovered, is massive amounts in the reverse reflecting an introgression of Eastern origin at the onset of Egyptian civilization as we know it.

Get the word out on this video. - Saturday May 28 2011 8:02 am The brown trout (Salmo trutta morpha fario and S. trutta morpha lacustris) and the sea trout (S. trutta morpha trutta) are fish of the same species. They are distinguished chiefly by the fact that the brown trout is largely a freshwater fish, while the sea trout shows anadromous reproduction, migrating to the oceans for much of its life and returning to freshwater only to spawn. Sea trout in the UK and Ireland have many regional names including sewin (Wales), finnock (Scotland), peal (West Country), mort (North West England) and white trout (Ireland). The specific epithet trutta derives from the Latin trutta, meaning, literally, 'trout'. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although there is some evidence of stocks that spawn on wind-swept shorelines of lakes. S. trutta morpha fario form stream-resident populations, typically in alpine streams but sometimes in larger rivers. There is evidence that anadromous and non-anadromous morphs coexisting in the same river can be genetically identical. In common usage, the name 'brown trout' is often applied indiscriminately to the various morphs. The brown trout is normally considered to be native to Europe and Asia but the natural distribution of the ...

  • Thesis 52 Thesis 52 ll people without significant agricultural ancestry should revert to patterns of nutrition and activity which have physiological effects like those of hunter-gatherer lifestyles, in order to slow their aging and hasten its cessation. The case of individuals who do not come from long-established agricultural populations is much less ambiguous. All such individuals should avoid (i) agricultural foods, (ii) exposure to the abundant pathogens harbored by agricultural societies, and (iii) activity patterns more appropriate to the cultivation of crops or the herding of dairy animals. Individuals with such ancestry who avail themselves of modern medicine, sanitation, vaccination, and the like, but avoid the forgoing environmental factors, could have their medical prospects can be transformed. As Lindeberg documents extensively in his book "Food and Western Disease," such individuals can obtain dramatic relief from chronic Western diseases by avoiding the diet and activity patterns of the Western lifestyle. His data show a dramatic improvement with respect to the risks and debilitation of specific chronic medical conditions, such as diabetes, among those who have done this. In Hamiltonian terms, what occurs with such lifestyle transitions, among individuals with non-agricultural ancestry, is a recovery of high levels of adaptation, or Darwinian fitness, upon reversion to the physiological environment to which these populations are well-adapted. If the tools of modern ...
  • Tom Rojo Poller / Nicolas Wiese - Installation Der Garten der Pfade die sich verzweigen Tom Rojo Poller / Nicolas Wiese Audiovisual installation Premiered at Hoerensehen 2.0 festival Berlin, November 2009 El Jardín de senderos que se bifurcan [The Garden of Forking Paths] is a short story by Jorge Luis Borges that evokes the notion of a maze of „proliferating and forking times. This metaphor inspired the authors approach of combining installation and concert elements, thus trying to induce a labyrinthine, ramified and interlaced audiovisual experience. The work offers, two temporal perspectives on the same audiovisual material: a static, circulating one consisting of a purely electroacoustic phase, and a dynamic and dircted concert phase in which a score-based composition with a duration of two hours is performed by seven musicians. Apart from the internal structural interlacings of the visual and acoustic layers, also the spacial disposition of the projections and the sound sources play an important role, offering the audience different positions and nested perspectives. The authors collaborated after a first conceptional stage in Berlin by communicating between Paris and Berlin via the internet, exchanging sketches, images and, above all, elctroacoustic samples.

  • Hybridization between Native California tiger salamanders McIVER, WILLIAM RUS Fish and Wildlife Service, Ventura, California 93003, bill_mciver@fws.gov Hybridization between Native California tiger salamanders (Ambystoma californiense) and Non-native Tiger Salamanders (Ambystoma tigrinum): Developing Management Strategies The California tiger salamander (Ambystoma californiense) is federally listed as endangered in Sonoma and Santa Barbara Counties, and threatened in central California. Non-native barred tiger salamanders (Ambystoma tigrinum mavortium) were introduced into central California as fishing bait in the mid-1900s. The threat of hybridization with non-native tiger salamanders is particularly severe in the Central Coast Range and Bay Area regions, and, to a lesser extent, the Central Valley region. Hybridization between species may lead to introgression, which occurs when hybrid individuals repeatedly backcross to one or both parental types so that genetic material is transferred between the two species. Natural hybridization can be an important component of evolutionary processes; however, hybridization and introgression can be cause for concern, particularly if they are the result of human activities such as the introduction of non-native taxa. Management strategies regarding hybridization in native California tiger salamanders need to be developed through cooperation between Federal and State agencies, researchers, consultants, and private landowners.
