Some Microbiology:

Bacterial cells in the body outnumber human cells by a factor of 10 to 1. Yet only recently have researchers begun to elucidate the beneficial roles these microbes play in fostering health.
Some of these bacteria possess genes that encode for beneficial compounds that the body cannot make on its own. Other bacteria seem to train the body not to overreact to outside threats.
Advances in computing and gene sequencing are allowing investigators to create a detailed catalogue of all the bacterial genes that make up this so-called microbiome.
Unfortunately, the inadvertent destruction of beneficial microbes by the use of antibiotics, among other things, may be leading to an increase in autoimmune disorders and obesity.

“There is a confusion about science. We don’t know everything right away. We have ideas and speculations and you might have a theory before you have a premise confirmed—experimental data, before you know what it means…"

How Science of animal colours helping us:
Birds, butterflies, squid and other creatures often sport intense or changing colors that are not formed by pigments but by highly organized nanostructures that researchers are only beginning to unravel.
Orderly and disorderly geometric patterns of these nanostructures reflect only certain wavelengths of light, creating specific colors that in some cases can also shift if the structures get wet or if their dimensions change.
Scientists are making synthetic materials that mimic these biological structures, which could lead to cars or dresses that change color as they move, sensors that detect impurities in drinking water, efficient optical chips for cell phones and authentication marks on credit cards that are exceedingly hard to counterfeit.

MUTAMORPHOSIS II: TRIBUTE TO UNCERTAINTY INTERNATIONAL CONFERENCE Prague
6 - 8 December 2012
Do you have something original to say about our world that is increasingly fuzzy, unstable and chaotic? Are you interested in how crisis, uncertainty and complexity can come together in order to question the known as well as predict and/or model yet unknown? Do you want to share projects intrinsically linking domains of scientific, artistic and technological research and creativity that can be introduced as relevant tools for better understanding of our common future? We invite you to respond to the Tribute to Uncertainty theme.

Why do People Die While Running Marathons?

Heatstroke can certainly be a factor, as can hyponatremia -- low sodium levels in the blood often caused by drinking too much water during exercise. However, in the vast majority of cases, people die during marathons because of a heart attack. Marathon running puts an extraordinary stress on your heart, one that your body was not designed for.

It's a classic example of a concept known as "the reverse effect" – where too much of something that is normally good for you can have the opposite impact. According to a study presented at the Canadian Cardiovascular Congress 2010 in Montreal, regular exercise reduces cardiovascular risk by a factor of two or three.

Research by Dr. Arthur Siegel, director of Internal Medicine at Harvard's McLean Hospital, also found that long-distance running leads to high levels of inflammation that may trigger cardiac events,ⁱⁱⁱ and a separate study published in Circulation found that running a marathon lead to abnormalities in how blood was pumped into the heart.^{Research by Dr. Arthur Siegel, director of Internal Medicine at Harvard's McLean Hospital, also found that long-distance running leads to high levels of inflammation that may trigger cardiac events,iii and a separate study published in Circulation found that running a marathon lead to abnormalities in how blood was pumped into the heart.iviv}

Does literature impact what scientists study?

How does art inspire science? It may seem a difficult question to answer with any empirical evidence, but in a new research project Scottish scientists aim to do just that.

Launched yesterday, What Scientists Read? will aim to find out what influence literature has on scientists and the decisions they make.

Asking questions like “how does reading literature affect scientific thought and practice?” and “does reading literature affect the career decision to become a scientist?”, the project team will conduct interviews with scientists in Scotland to try to unravel the influence on science of the creative arts.

Fear not, though. Even if you’re ruled out of the interviews due to geographical disadvantages you can still take part in the study. The project’s website hosts a forum where any scientist can go and add to the discussion.

The launch of the project is great timing. At the crossroads between science and art there has long been debate about how the arts feed back into scientific research - whether as a justification for the art or for the funding - but for ArtLab nothing is going to be as compelling as some cold, hard scientific fact.

Science can be neither conquered nor defended by armies and its advancement will change the way humans govern themselves. Science cannot be controlled or arrested. Science doesn't respect distances or frontiers or laws. The major thing is the world is becoming ungovernable. The real force in our time is no longer politics, but science. And science took away the strengths of politics. Citizens now must be persuaded rather than ordered in this new age of knowledge - Israeli President Shimon Peres
