Christina Zielinski: With the Immune System's Weapons - 0 views

  •  
    "When the right microorganisms are at work, immune cells involved in the development of autoimmune illnesses like psoriasis, multiple sclerosis and arthritis, can develop anti-inflammatory properties. Scientists at Charité - Universitätsmedizin Berlin and the Institute for Research in Biomedicine, Bellinzona, Switzerland, have now made this discovery. Their work is published in the current issue of the scientific journal Nature*. The scientists were able to prove that particular fungi activate the immune cells involved in the development of certain illnesses, whereas other microorganisms, in particular bacteria that are found naturally on our skin, lend an anti-inflammatory function to them. "This not only demonstrates that the composition of our microflora has a decisive role in the development of chronic illnesses, but also that the key cells causing illness can develop an anti-inflammatory 'twin'," explained Dr. Christina Zielinski, first author of the study."

Massive open online course - Wikipedia, the free encyclopedia - 0 views

  •  
    A Massive open online course (MOOC) is a course where the participants are distributed and course materials also are dispersed across the web. This is possible only if the course is open, and works significantly better if the course is large. The course is not a gathering, but rather a way of connecting distributed instructors and learners across a common topic or field of discourse.[1] MOOCs are a more recent form of online course development --

John Cryan: Mind-Altering Bugs - ScienceNOW - 0 views

  •  
    "Hundreds of species of bacteria call the human gut their home. This gut "microbiome" influences our physiology and health in ways that scientists are only beginning to understand. Now, a new study suggests that gut bacteria can even mess with the mind, altering brain chemistry and changing mood and behavior. In recent years, researchers have become increasingly interested in how gut bacteria might influence the brain and behavior, says John Cryan, a neuroscientist at University College Cork in Ireland. So far, most of the work has focused on how pathogenic bugs influence the brain by releasing toxins or stimulating the immune system, Cryan says. One recent study suggested that even benign bacteria can alter the brain and behavior, but until now there has been very little work in this area, Cryan says."

Noise and Signal - Nassim Taleb | Farnam Street - 0 views

  •  
    "There is a biological story with information. I have been repeating that in a natural environment, a stressor is information. So too much information would be too much stress, exceeding the threshold of antifragility. In medicine, we are discovering the healing powers of fasting, as the avoidance of too much hormonal rushes that come with the ingestion of food. Hormones convey information to the different parts of our system and too much of it confuses our biology. Here again, as with the story of the news received at too high a frequency, too much information becomes harmful. And in Chapter x (on ethics) I will show how too much data (particularly when sterile) causes statistics to be completely meaningless. Now let's add the psychological to this: we are not made to understand the point, so we overreact emotionally to noise. The best solution is to only look at very large changes in data or conditions, never small ones"

The Neuroscience of Effort | Wired Science | Wired.com - 0 views

  •  
    "Rather, these successful men needed to also be blessed with "zeal and with capacity for hard labour." This study is a first glimpse into those essential qualities described by Galton, helping us map out the individual differences that make it slightly easier for some people to engage in hard labor. These diligent souls seem to get a bit more pleasure from the possibility of reward, but they also seem less sensitive to their inner complainer, that disruptive voice reminding them that minesweeper is more fun than editing, or that the ballgame on television is much more entertaining than their homework. At any given moment, there is a tug of war unfolding in our head, determining whether or not we're willing to put in the effort. This sentence only exists because, for a few minutes at least, I was able to win the war."

Chris Mooney | The Science of Debiasing: The New "Debunking Handbook" Is a Treasure Tro... - 0 views

  •  
    "I simply cannot believe that John Cook of Skeptical Science and psychologist Stephan Lewandowsky managed, in just 8 pages, to create something as magnificent as their new Debunking Handbook. It is packed not only with wonderful graphics, but also with a clear explanation of why many attempts to defeat misinformation fail, and what steps must be taken to do a better job. The core issue, of course, is one that I've written much about-too many scientists assume that that facts win out on their own, but that isn't actually true"

Science - Quora - 0 views

  •  
    "Science is a scheme for thinking and solving issues using evidence. It requires hypotheses, i.e. potential truths that require examination. A hypothesis or scientific idea is only as strong as the evidence to support it. Strong evidence is predictive and reproducible, weak evidence is less so. Scientific thinking gives greater weight to the stronger evidence base."

YaCy 'KIT-sn-head': About - 0 views

  •  
    Sciencenet - Towards a global search and share engine for all scientific knowledge. We have developed a prototype distributed scientific search engine technology, "Sciencenet", which facilitates rapid searching over this large data space. By "bringing the search engine to the data" we do not require server farms. This platform also allows users to contribute to the search index and publish their large scale data to support e-Science. Furthermore, a community-driven method guarantees that only scientific content is crawled and presented. Our peer-to-peer approach is sufficiently scalable for the science web without performance or capacity tradeoff.

The Overview Effect.... Will change your world - 0 views

  •  
    It refers to the experience of seeing firsthand the reality of the Earth in space, which is immediately understood to be a tiny, fragile ball of life, hanging in the void, shielded and nourished by a paper-thin atmosphere.  From space, the astronauts tell us, national boundaries vanish, the conflicts that divide us become less important and the need to create a planetary society with the united will to protect this "pale blue dot" becomes both obvious and imperative.  Even more so, many of them tell us that from the Overview perspective, all of this seems imminently achievable, if only more people could ha

    The event horizon telescope will only photograph the proximity to the event horizon, not the black hole itself which by definition remains invisible. If it succeeds it will be the first actual proof that black holes exist.

Georg Pohnert: Chemists reveal how algae delete unwanted 'competitors' - Shychemist - 0 views

  •  
    "Every morning when the sun comes up, the ocean ground is radically cleaned. As soon as the first rays of sunlight find their way into the water, the microalgae "Nitzschia cf pellucida" start their deadly 'morning hygiene'. The algae, the size of only some few micrometers, wrap themselves and their surroundings in a highly toxic poison: cyanogen bromide, a chemical relative of hydrocyanic acid, although much more toxic."

Biological Link between Cancer and Depression - The Naked Scientists May 2009 - 0 views

  •  
    "Leah Pyter: Well basically what we know is that patients with cancer have a higher likelihood of also developing depression at some point in their disease progression, so whether that occurred before and is predisposing them to cancer, or it's due to the tumours themselves, or other aspects of having the disease, we don't know. We were only studying right now whether the cancer itself can cause depression. Chris Smith: How could a tumour trigger depression, because a tumour can occur anywhere in the body, therefore at the remote sites in the brain, so how could it trigger changes in brain activity? Leah Pyter: Sure, well what we hypothesized was that the tumours themselves can produce cytokines which has been shown before. Chris Smith: These are inflammatory chemicals that drive the immune system? Leah Pyter: Right, exactly! And there is also a pile of research on how cytokines can access the brain specifically regions of the brain that are associated with depression and anxiety and emotional behaviours, and they can access the brain both tumourally through the blood, or neurally through the vegas nerves.

Marta Soares Tactile stimulation lowers stress in fish : Nature Communications : Nature... - 0 views

  •  
    "In humans, physical stimulation, such as massage therapy, reduces stress and has demonstrable health benefits. Grooming in primates may have similar effects but it remains unclear whether the positive effects are due to physical contact or to its social value. Here we show that physical stimulation reduces stress in a coral reef fish, the surgeonfish Ctenochaetus striatus. These fish regularly visit cleaner wrasses Labroides dimidiatus to have ectoparasites removed. The cleanerfish influences client decisions by physically touching the surgeonfish with its pectoral and pelvic fins, a behaviour known as tactile stimulation. We simulated this behaviour by exposing surgeonfish to mechanically moving cleanerfish models. Surgeonfish had significantly lower levels of cortisol when stimulated by moving models compared with controls with access to stationary models. Our results show that physical contact alone, without a social aspect, is enough to produce fitness-enhancing benefits, a situation so far only demonstrated in humans"

Anthony Ives, Stephen Carpenter: Stability and Diversity of Ecosystems - 0 views

  •  
    "Understanding the relationship between diversity and stability requires a knowledge of how species interact with each other and how each is affected by the environment. The relationship is also complex, because the concept of stability is multifaceted; different types of stability describing different properties of ecosystems lead to multiple diversity-stability relationships. A growing number of empirical studies demonstrate positive diversity-stability relationships. These studies, however, have emphasized only a few types of stability, and they rarely uncover the mechanisms responsible for stability. Because anthropogenic changes often affect stability and diversity simultaneously, diversity-stability relationships cannot be understood outside the context of the environmental drivers affecting both. This shifts attention away from diversity-stability relationships toward the multiple factors, including diversity, that dictate the stability of ecosystems."
