Analyses conducted by researchers from Université Laval’s Center for Northern Studies reveal that aquatic life in Ward Hunt Lake, the continent’s northernmost lake, is affected by climate change.

Ward Hunt Lake is a body of water located on a small island north of Ellesmere Island in the Canadian Arctic, has undergone major transformations within the last two centuries. The speed and range of these transformations—unprecedented in the lake’s last 8,000 years—suggest that climate change related to human activity could be at the source of this phenomenon.

The researchers’ conclusions are based on the analysis of a sediment core extracted in the center of Ward Hunt Lake in August 2003.

World Wildlife Fund scientists said today that the discovery of 11 new animal and plant species in a remote area in central Vietnam underscores the importance of conservation efforts in the ancient tropical forests of the region.

Within the ancient tropical forests of a region known as Vietnam's "Green Corridor," scientists found a snake, five orchids, and two butterflies as well as three other plants new to science and exclusive to the Annamites Mountain Range. Ten other plant species, including four orchids, are still under examination but also appear to be new species.

'Quitting' in the face of insurmountable obstacles is the antithesis of American culture. John Henry died rather than give up against a machine trying to lay railroad track faster than him. Few successful businessmen have denied they worked their way through doubt and financial peril to succeed.

It would seem that persistence would be mentally beneficial over the long haul; hanging in there should increase the odds of personal success and personal success is closely linked to well-being. But what if the goal is extremely unlikely?

Melting icecaps and ‘climate chaos’ have put climate change at the top of the agenda for the UN General Assembly’s meeting this week. The meeting is a precursor to the November meeting in Bali where leaders will try to agree on a successor to the Kyoto Protocol.

A new Institute of Physics’ (IOP) report, Climate change prediction: A robust or flawed process?, published today reveals that while there is general consensus on the underlying causes of the changes in our atmosphere, there is not unanimity.

World leaders have been influenced by one very important document that drew its conclusions after wide consultation in the international science community, the IPCC Summary for Policymakers of the Scientific Assessment.

Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource.

The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that the collagen can be used commercially.

L.S. Fan, Distinguished University Professor of chemical and biomolecular engineering at Ohio State, said that he and former Ohio State doctoral student, Mahesh Iyer, hit upon the idea when they were trying to improve a method of hydrogen production called the water-gas-shift reaction.

Several times over the past century, scientists and environmental engineers have proposed spreading slurries of dissolved iron into the oceans in order to “fertilize” the waters and promote vast blooms of marine plants (phytoplankton). Phytoplankton consume carbon dioxide as they grow, and this growth can be stimulated in certain ocean basins by the addition of iron, a necessary micronutrient.

Though common on land, dissolved iron is often rare in the ocean. Some researchers and commercial interests have recently proposed to provide that missing nutrient on a large scale in order to create artificial blooms.
