New Geoengineering Approaches Offset Global Warming More Efficiently

Releasing engineered nano-sized disks or sulphuric acid, a condensable vapour, above the Earth are two novel approaches that offer advantages over simply putting sulphur dioxide gas into the atmosphere, says Dr. David Keith, a University of Calgary climate scientist.

Solar-Powered, Oil-Cleaning Robots: Solution for Oil Spill?

A team of researchers at MIT's SENSEable City Laboratory have developed Seaswarm, a robot that autonomously navigates the water’s surface and uses nanofibers to absorb 20 times its weight in oil, which could be made into a viable solution for cleaning up the Gulf oil spill.

Should the FDA approve genetically engineered salmon?

This week's Question of the Week concerns the issue of genetically engineered food. A firm in Waltham, MA, has developed a genetically modified salmon that grows during the winter as well as the summer, so it reaches an 8-pound market weight in 18 months instead of 36. Accomplished by inserting part of a gene from an ocean pout into the growth gene of a Chinook salmon and then injecting the blended genetic material into the fertilized eggs of a North Atlantic salmon, the FDA is in the process of reviewing what would be the nation's first commercial genetically modified food animal. What do you think? Should the FDA approve genetically engineered salmon? Yes or No?

Should BP be permitted to continue to drill in the Gulf of Mexico?

This week's Question of the Week concerns the BP oil spill in the Gulf of Mexico. According to recent news reports, BP said they may drill a new well in the Macondo reservoir -- the source of one of the world's worst oil spills. Proponents believe that BP's earnings from drilling in the Gulf would allow them to pay the massive fines and costs for cleanup of the spill, while opponents believe the oil giant should sell the rights to the reservoir to another oil company and donate the proceeds from the sale. What do you think? Should BP be permitted to continue to drill in the Gulf of Mexico? Yes or No?
