Ozone Layer is RecoveringEarth’s protective ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported in a rare piece of good news about the health of the planet.Scientists said the development demonstrates that when the world comes together, it can counteract a brewing ecological crisis. For the first time in 35 years, scientists were able to confirm a statistically significant and sustained increase in stratospheric ozone, which shields the planet from solar radiation that causes skin cancer, crop damage and other problems.Read more: http://www.laboratoryequipment.com/news/2014/09/ozone-layer-recovering

Damn shame the evil, fascist, mining-owned, neo-conservative Abbott Government has REMOVED Australia’s Carbon AND Mining Taxes to appease their masters.

Chemists Study Mechanisms Behind Food SpoilageThe research team of Annette Rompel from the Institute for Biophysical Chemistry, Univ. of Vienna has explored the mechanisms behind the “browning reaction” during the spoilage of mushrooms. They were able to demonstrate that the enzyme responsible is already formed prior to fungal spoiling. The detailed study is published online in Phytochemistry and Acta Crystallographica.Understanding the mechanism of enzyme tyrosinase pigmentation is currently of both medical as well as technological interest. The copper-containing enzyme is present in animals and humans and is essential for the protective pathway against UV radiation, it also simultaneously provides the elucidation and potential means with which to prevent the spoilage of food. Mushrooms were selected for the study because of their low cost and ready availability. In addition they are also a valuable target for researchers, largely because of their high enzyme content, fungi are ideal sources for potential studies of tyrosinase. The mushrooms therefore serve as a model organism for the study of the pathway involved in food spoilage.Read more: http://www.laboratoryequipment.com/news/2014/09/chemists-study-mechanisms-behind-food-spoilage

This woman deserves a round of applause and a throne of gold. This is the most realistic & amazing thing for someone to say for this generation of students. I wasn’t able to go to college this year because my parents can’t afford to send me and I had every scholarship, grant, loan known to man and it still wouldn’t work. Finally someone gets it!

The world we’ve created for birds is a gauntlet of death. This infographic, based on Smithsonian research included in the just released State of the Birds report, shows how our actions impact their population numbers. The report’s release coincides with the 100th anniversary of the death of “Martha” the last passenger pigeon, a species that once numbered in the billions but was hunted to extinction. The report is the most comprehensive look at U.S. birds and the news isn’t great: 228 birds species are currently at risk of extinction. But the good news is that we can fix it. The report indicates that many species have rebounded with dedicated conservation efforts. Read our summary or the full report.

“What is in a name? I remember a conversation with a distinguished scientist keen to rubbish “all that Gaia nonsense”. When I protested and offered to rename it “geophysiology”, “earth systems science” or something similar, he brightened up and eventually confessed that “most of it must be right”. The choice of the Greek goddess Gaia rather than of some Greek-derived scientific polysyllable, or, worse, some acronym, was a risk. On the one hand it was just too attractive for those in search of a new religion at a time when traditional religions were breaking down; on the other it was just too repulsive for those who liked to hide their science in coded vocabulary. The result was that some New Age travellers jumped aboard, and some otherwise sensible scientists jumped off.
This is probably still the case. But as a theory, Gaia is now winning. The scientific communities of the four great international global change research programmes – the International Geosphere-Biosphere Programme (IGBP), the International Human Dimensions Programme on Global Environmental Change (IHDP), the World Climate Research Programme (WCRP) and the International Biodiversity Programme (Diversitas) – met at Amsterdam on 13 July 2001. They then adopted a Declaration on Global Change, signed by over a thousand people, which stated squarely that “the Earth System behaves as a single, self-regulating system, comprised of physical, chemical, biological and human components. The interactions and feedbacks between the component parts are complex and exhibit multi-scale temporal and spatial variability.”
Here indeed is Gaia theory. The same goes for the earth systems science which is now the concern of the Geological Society of London (with which the Gaia Society recently merged). Whatever the label, earth systems science, or Gaia, has now become a major subject of enquiry and research, and no longer has to justify itself.
- From “Earth Systems Science: Are We Pushing Gaia Too Hard?” a speech by Sir Crispin Tickell in 2006.

“Lovelock insists that this view of the relationship between life and the nonliving elements of the earth system does not require a spiritual explanation; even so, it evokes a spiritual response in many of those who hear it. It cannot be accidental, one is tempted to conclude, that the percentage of salt in our bloodstreams is roughly the same as the percentage of salt in the oceans of the world. The long and intricate interrelationship of all living and nonliving things may be explicable in purely scientific terms, but the simple fact of the living world and our place on it evokes awe, wonder, a sense of mystery—a spiritual response—when one reflects on its deeper meaning.”
– From “Earth in the Balance” by Al Gore. 1992

“For my money, the deepest, most beautiful scientific explanation is the Gaia hypothesis, the idea that Earth’s physical and biological processes are inextricably interwoven to form a self-regulating system. This notion—the 1965 brainchild of chemist James Lovelock, further co-developed with microbiologist Lynn Margulis—proposes that air (atmosphere), water (hydrosphere), earth (geosphere or pedosphere) and life (biosphere) interact to form a single evolving system capable of maintaining environmental conditions consistent with life… .
“Indeed I would go so far as to suggest that this idea can help shift the human perception of nature. In the modernist perspective, the natural world is little more than a collection of virtually infinite resources available for human exploitation. The Gaian lens encourages us to re-envision Earth-bound nature as an intertwined, finite whole from which we evolved, and in which we remain fully embedded. Here, then, is a deep and beautiful perspective in desperate need of broad dissemination.”
- From 2012 Blog by Scott Sampson, written “in response to literary agent John Brockman’s annual question. This year’s question was, “What is your favorite deep, elegant, or beautiful explanation?”
