Creative Citizen recently launched their public beta after being in private beta since September 2007. The two founders, Argam DerHartunian and Scott Badenoch, believe that their service is a key piece to what has been missing in the environmental movement.

Extended Producer Responsibility and the E-waste problem

The practice of Extended Producer Responsibility (EPR) is picking up steam, most notably in the information technology industry. A growing number of companies are taking on greater levels of responsibility for the environmental impacts of their products - from point of manufacturing through to end of the life recycling. E-waste recycling is taking off, but obstacles remain to its widespread practice in North America.

Smoking is addictive, but quitting is contagious
May 22, 2008 08:35 AM - Harvard Medical School

Over the last 30 years, the number of smokers in the U.S. has steadily decreased—a tribute to the efforts of public-health workers everywhere. And while this fact is unarguable, less obvious are the social and cultural forces that lead an individual to kick the habit. In fact, when someone crumbles that last empty pack of their favorite unfiltered brand and vows to never buy another, he might not realize that he is less like the heroic individual grasping his own boot straps and more like a single bird whose sudden left turn is just one speck in the larger flock.

Mechanical Fin Power: Oceanic Power Generation
May 21, 2008 09:29 AM - , Triple Pundit

Tim Finnigan, a professor of ocean engineering at the University of Sydney in Australia designed a radical oceanic energy collector inspired by the design of shark tails. Mimicking the successful evolutionary design of the fish species, he constructed a device that seizes the power of the sea. “I realized the systems that function the best are the ones that already exist there,” said Finnigan.

Honda to roll out cheap new hybrid model in early '09
May 21, 2008 03:53 AM - Reuters

TOKYO (Reuters) - Honda Motor Co <7267.T> said on Wednesday it would launch a new, low-cost hybrid car in Japan, North America and Europe in early 2009 as it seeks to cut the lead of Toyota Motor Corp <7203.T> in the green car race. Despite the pressure of record-high oil prices and concerns over climate change, fuel-efficient and low-emission hybrids still occupy a small niche in the global car market, partly due to their higher costs for both consumers and automakers.

The most sought-after structures for next generation computing found in beetles
May 20, 2008 09:18 AM - University of Utah

Researchers have been unable to build an ideal “photonic crystal” to manipulate visible light, impeding the dream of ultrafast optical computers. But now, University of Utah chemists have discovered that nature already has designed photonic crystals with the ideal, diamond-like structure: They are found in the shimmering, iridescent green scales of a beetle from Brazil.

Hydrogen fuel cells are future, says WWM boss

USING fuel cells powered by hydrogen will help the next generation of harbour tugs to cut emissions, according to Michiel Wijsmuller, managing director of WorldWise Marine Engineering (WWM). Part of the Offshore Ship Designers group, WWM is working with tug operators Ijmuiden-based Iskes and Rotterdam-based Smit to develop a 50 tonne bollard pull harbour tug that will have zero emissions when on standby and very low emissions in service.

Animated map brings global climate crisis to life
May 19, 2008 09:09 AM - Reuters

A new animated map of the earth from space illustrates the potential impact of climate change over the next century and can be viewed on your computer. The project, Climate Change in Our World, is the result of cooperation between web search engine Google, Britain's environment ministry and the country's Met Office.
