Geoengineering Experiment Cancelled Amid Patent Row
from Nature News
A field trial for a novel UK geoengineering experiment has been cancelled amid questions about a pre-existing patent application for some of the technology involved.
The Stratospheric Particle Injection for Climate Engineering (SPICE) project is a collaboration among several UK universities and Cambridge-based Marshall Aerospace to investigate the possibility of spraying particles into the stratosphere to mitigate global warming. Such particles could mimic the cooling produced by large volcanic eruptions, by reflecting sunlight before it reaches the Earth's surface.
But the field-trial arm of SPICE--which would have seen around 150 litres of water pumped into the atmosphere via a 1-kilometre hosepipe attached to a balloon--has now been abandoned.

PODCASTS: Expanding With the Cosmos
Using the Atacama Cosmology Telescope (ATC), a 6.5-meter microwave collector in Chile, cosmologists are piecing together the early history of the known universe. In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.
