Detectan Virus del Nilo Occidental en Nueva York | El Diario NY - 0 views

    Culex pipiens "Era sólo cuestión de tiempo. Por primera vez, durante esta temporada de mosquitos, el Departamento de Salud de Nueva York (DOHMH) ha detectado zancudos infectados con el virus del Nilo Occidental en la ciudad de Nueva York. "

Ilseung Cho, Martin Blaser wissenschaft.de - Gewichtige Folgen - 0 views

  •  
    "Es ist möglich, dass eine frühzeitige Exposition gegenüber Antibiotika den Stoffwechsel von Kindern umprogrammiert, sodass Übergewicht im späteren Leben entstehen kann", sagt Co-Autor Martin Blaser von der New York University School of Medicine. Er betont, dass noch weitere Forschung nötig sei, um diese Theorie zu bestätigen. Klar sei aber bereits: Alles was die Darmflora beeinflussen kann, sollte vorsichtig behandelt werden.

    "In einer Kammer, kaum mehr als zwei mal drei Meter groß, einer früheren Toilette, findet man Lisa Thalheims Labor. Ein paar Meter weiter schrauben andere an Fahrrädern, Lisa Thalheim ist hier aber einem genetischen Fingerabdruck auf der Spur. Das Stadtbad Wedding ist einer der ersten Orte in Deutschland, an dem Autodidakten wie sie ihrer Liebe zur Gentechnik nachgehen können. "Software des Lebens" "Eine große Zukunft für die Biotechnologie-Industrie", hat der in Amerika als Naturwissenschafts-Papst verehrte Freeman Dyson vor fünf Jahren in der New York Review of Books vorhergesagt. Wenn sie dem Weg der Computerindustrie folge, "wenn sie klein und häuslich wird, statt groß und zentralisiert." Das scheint nun zu geschehen."

Andrew Gallup: Mund auf: Gähnen kühlt das Gehirn - SPIEGEL ONLINE - Nachricht... - 0 views

  •  
    "Ein kräftiges Gähnen fördere den Wärmeaustausch im Gehirn, erklären die Forscher Andrew und Gordon Gallup der State University of New York in Albany im Fachmagazin "Evolutionary Psychology" (Bd. 5, S. 92). Sogar der ansteckende Effekt eines zum Gähnen geöffneten Mundes habe einen evolutionären Sinn: So werde die Aufmerksamkeit einer ganzen Gruppe gesteigert."

Mental problems gave early humans an edge - life - 07 November 2011 - New Scientist - 0 views

  •  
    Some argue that these genes bring benefits - mental illness and genius have a long-standing link - but archaeologist Penny Spikins at the University of York, UK, goes further. She believes that mental illness and conditions such as autism persist at such high levels because in the past they were advantageous to humanity. "I think that part of the reason Homo sapiens were so successful is because they were willing to include people with different minds in their society - people with autism or schizophrenia, for example."

    "4. Genspace and BioCurious For letting the everyman explore the hidden corners of science. Community laboratories like Genspace, based in Brooklyn, New York, and BioCurious, based in Sunnyvale, California, are attracting biotech hackers interested in bridging the gulf that separates synthetic biology researchers from, well, everyone else"

The Epidemic of Mental Illness: Why? by Marcia Angell | The New York Review of Books - 0 views

  •  
    It seems that Americans are in the midst of a raging epidemic of mental illness, at least as judged by the increase in the numbers treated for it. The tally of those who are so disabled by mental disorders that they qualify for Supplemental Security Income (SSI) or Social Security Disability Insurance (SSDI) increased nearly two and a half times between 1987 and 2007-from one in 184 Americans to one in seventy-six. For children, the rise is even more startling-a thirty-five-fold increase in the same two decades. Mental illness is now the leading cause of disability in children, well ahead of physical disabilities like cerebral palsy or Down syndrome, for which the federal programs were created.

TEDxRheinMain - Prof. Dr. Thomas Metzinger - The Ego Tunnel - YouTube - 1 views

  •  
    Brain, bodily awareness, and the emergence of a conscious self: these entities and their relations are explored by Germanphilosopher and cognitive scientist Metzinger. Extensively working with neuroscientists he has come to the conclusion that, in fact, there is no such thing as a "self" -- that a "self" is simply the content of a model created by our brain - part of a virtual reality we create for ourselves. But if the self is not "real," he asks, why and how did it evolve? How does the brain construct the self? In a series of fascinating virtual reality experiments, Metzinger and his colleagues have attempted to create so-called "out-of-body experiences" in the lab, in order to explore these questions. As a philosopher, he offers a discussion of many of the latest results in robotics, neuroscience, dream and meditation research, and argues that the brain is much more powerful than we have ever imagined. He shows us, for example, that we now have the first machines that have developed an inner image of their own body -- and actually use this model to create intelligent behavior. In addition, studies exploring the connections between phantom limbs and the brain have shown us that even people born without arms or legs sometimes experience a sensation that they do in fact have limbs that are not there. Experiments like the "rubber-hand illusion" demonstrate how we can experience a fake hand as part of our self and even feel a sensation of touch on the phantom hand form the basis and testing ground for the idea that what we have called the "self" in the past is just the content of a transparent self-model in our brains. Now, as new ways of manipulating the conscious mind-brain appear on the scene, it will soon become possible to alter our subjective reality in an unprecedented manner. The cultural consequences of this, Metzinger claims, may be immense: we will need a new approach to ethics, and we will be forced to think about ourselves in a fundamentally new way. At

RNA world easier to make : Nature News - 0 views

  • John Sutherland and his colleagues from the University of Manchester, UK
  • ribonucleotide
  • building block of RNA
  • ...29 more annotations...
  • Donna Blackmond, a chemist at Imperial College London.
  • strong evidence for the RNA world
  • 'RNA world' hypothesis, which suggests that life began when RNA, a polymer related to DNA that can duplicate itself and catalyse reactions
  • chemists had thought the subunits would probably assemble themselves first, then join to form a ribonucleotide
  • three distinct parts: a ribose sugar, a phosphate group and a base
  • RNA polymer is a string of ribonucleotides
  • efforts to connect ribose and base together have met with frustrating failure
  • researchers have now managed to synthesise
  • ribonucleotides
  • remedy is to avoid producing separate ribose-sugar and base subunits
  • makes a molecule whose scaffolding contains a bond that will
  • be the key ribose-base connection
  • atoms are then added around this skeleton
  • final connection is to add a phosphate group
  • influences the entire synthesis
  • acting as a catalyst, it guides small organic molecules into making the right connections
  • What we have ended up with is molecular choreography
  • objectors to the RNA-world theory say the RNA molecule as a whole is too complex to be created using early-Earth geochemistry
  • flaw is in the logic — that this experimental control by researchers in a modern laboratory could have been available on the early Earth
  • Robert Shapiro, a chemist at New York University
  • early-Earth scenarios
  • heating molecules in water, evaporating them and irradiating them with ultraviolet light
  • results showing that they can string nucleotides together
  • ultimate goal is to get a living system (RNA) emerging from a one-pot experiment
  • need to know what the constraints on the conditions are first
  • Shapiro sides with
  • another theory of life's origins
  • because RNA is too complex to emerge from small molecules, simpler metabolic processes
  • eventually catalysed the formation of RNA and DNA
