Using Feedback to Control Weight
Recent research has shown that exhaust from lungs (part of excretion) is a major factor in weight loss. Burning 10 kg human fat requires inhalation of 29 kg oxygen. This produces 28 kg carbon dioxide and 11 kg water. As food and drinks are temporarily stored in the human stomach and bowels, the body weight is instantaneously increased with the weight of any food or drink consumed. Metabolism is usually divided into catabolism and anabolism, where catabolism is the process of breaking down ... 1

Physiological Decline in the Body When You Stop Exercising
...regular endurance exercise leads to four major consequences:
Increased ability of the heart to eject blood
increased ability of the blood vessels to send blood to where blood is needed
Increased number of capillaries (the vessels that deliver oxygen and ‘food’ to the muscles)
increased size and the number of mitochondria (the “power plants” of the cells).
All these changes lead to the more efficient use of oxygen, as well as nutrients.

Resveratrol and SIRT1
For the last decade, the science of aging has increasingly focused on sirtuins, a group of genes that are believed to protect many organisms, including mammals, against diseases of aging. Mounting evidence has demonstrated that resveratrol, a compound found in the skin of grapes as well as in peanuts and berries, increases the activity of a specific sirtuin, SIRT1, that protects the body from diseases by revving up the mitochondria, a kind of cellular battery that slowly runs down as we age. ...Folksonomies: longevity supplements

Human Respiration is Carbon Neutral
The very first time you learned about carbon dioxide was probably in grade school: We breathe in oxygen and breathe out carbon dioxide. Any eight-year-old can rattle off this fact. More specifically, the mitochondria within our cells perform cellular respiration: they burn carbohydrates (in the example shown below, glucose) in the oxygen that we breathe in to yield carbon dioxide and water, which we exhale as waste products, as well as energy, which is required to maintain...
1 We exhale carbon and that carbon is sequestered in the next plant we eat.
Summaries of comments made during the science art session by artists and audience members:
- Hawks – interested in reconstruction, detailed realism, Neanderthal terminator, there is a tradition in anthropology of illustrating, Neanderthal are reconstructed to look doomed and confused, like it when illustrators and artists bring humanity into them, humor, Kenise Brothers give smiles to them, pose them, which isn’t scientific because we don’t know these things, but also more scientific because it isn’t so clinical
- Orr – orogenic.blogspot.com geometric, abstract illustrations of birds
- Links ot other artists on the wiki page: Carl Buell, etc http://scio11.wikispaces.com/Science-Art
- Radiohead/Nine Inch Nails Model: put a lot free stuff online in hopes of eventually being hired to do something custom, people expect images for free
- Criticism of Mellow's Darwin painting: the steps were too linear, it should have been a bush growing out of his head
- Svpow.wordpress.com – fantasy images of brachiosaurs, not scientifically accurate, but memorable. Brian Ang.
- My Favorite Anthropology Sculpture of Homo Erectus at the Hall of Human Origins - post a link to this image in the wiki.
- The monkey rising to become man iconic image is really wrong and hurts evolution’s image outside of the field. Mitochondria is another example, in cells they are not blobs, but are networked.
