WorldChanging has a brief post pointing to a symposium on urban life after oil - Re-Imagining Cities: Urban Design After the Age of Oil. A number of great journalists were covering last weekend's Re-Imagining Cities: Urban Design After the Age of Oil symposium in Philadelphia. The University of Pennsylvania School of Design and Penn Institute for Urban Research hosted this conference, which was organized with support from the Rockefeller Foundation to address the need to re-imagine and rethink how cities are designed and organized in a future without oil. Our own Alex Steffen gave a mainstage talk at the international event, which featured a number of thinkers whose work we've written about before here, like Bull Dunster, Elizabeth Kolbert, Robert Socolow, Andy Revkin, William J. Mitchell, David Orr, Neal Pierce, Bill Rees, Thomas Campanella, Harrison Fraker, and ARUP's Sir Peter Head. From brief recaps of plenaries and workshops to lengthier discussions of the theories presented (and their presenters), the pieces posted to the Next American City liveblog offer a taste of what was seen and heard at this innovative gathering of great minds.

The US could replace all its cars and trucks with electric cars powered by wind turbines taking up less than 3 square kilometres - in theory, at least. That's the conclusion of a detailed study ranking 11 types of non-fossil fuels according to their total ecological footprint and their benefit to human health. The study, carried out by Mark Jacobson of the atmosphere and energy programme at Stanford University, found wind power to be by far the most desirable source of energy. Biofuels from corn and plant waste came right at the bottom of the list, along with nuclear power and "clean" coal.

What Is Appendicitis? How to diagnose Appendicitis? Where is Appendix pain located In this article, we hope you can find all of your answers related to Appendicitis. We covered everything about Appendicitis. We discussed types, causes, symptoms, tests, and treatment of Appendicitis.

Appendicitis is an inflammation of the appendix, which is a small tube of intestinal tissue that projects from the large intestine. While the appendix does not seem to have a particular function, one theory suggests that it acts as a storehouse of good bacteria and boosts immunity after diarrheal illness. However, some experts believe the appendix is just a purposeless remnant from our evolutionary past. One thing we're sure of is that we can live without it, without any apparent consequences.

Hiccups are an uncontrollable reflex of the human body. What exactly goes on within the body to generate this weird sound is highly debated. The fact that hiccups can be heard and seen from fetuses suggests that the central circuit involved in producing hiccups...

Hiccups are unwanted contractions of the diaphragm - the muscle that participates in breathing. Although evolutionary scientists have a few theories, the exact cause and purpose of hiccups is unknown. They remain a unique and age-old feature of the human physiology that continues to elude scientists to this day.
