Report: Hot Rocks Keep N. America Afloat - If it weren't for the hot rocks down below Earth's crust, most of North America would be below sea level, report researchers who say the significance of Earth's internal heat has been overlooked.

Greenhouse gas burial - Deep coal seams that are not commercially viable for coal production could be used for permanent underground storage of carbon dioxide (CO2 ) generated by human activities, thus avoiding atmospheric release, according to two studies published in Inderscience's International Journal of Environment and Pollution. An added benefit of storing CO2 in this way is that additional useful methane will be displaced from the coal beds.

Nanoparticles hitchhike on red blood cells: a potential new method for drug delivery - Researchers at the University of California, Santa Barbara have discovered that attaching polymeric nanoparticles to the surface of red blood cells dramatically increases the in vivo lifetime of the nanoparticles. The research, published in the July 07 issue of Experimental Biology and Medicine, could offer applications for the delivery of drugs and circulating bioreactors.

Transparent transistors to bring future displays, 'e-paper' - Researchers have used nanotechnology to create transparent transistors and circuits, a step that promises a broad range of applications, from e-paper and flexible color screens for consumer electronics to "smart cards" and "heads-up" displays in auto windshields.

Push to legalize Afghanistan's opium trade - Afghanistan produces more than 90% of the world's illegal opium. Current control methods involve literally ripping up poppy fields, mainly under the oversight of the United States and the North Atlantic Treaty Organisation. But the Senlis Council, an international policy think-tank with a base in London, has another suggestion: allow the farmers to grow their poppies and process them locally to make morphine tablets under a controlled licensing scheme.
