CFC Reduction Induces Ozone Layer Fixing

A new MIT-led study confirms that the Antarctic ozone layer is healing as a direct result of global efforts to reduce ozone-depleting substances such as chlorofluorocarbons or CFCs. This is significant because scientists have observed signs of ozone recovery in the past. However, the new study is the first to show, with high statistical confidence, that this recovery is due primarily to the reduction of ozone-depleting substances, instead of other influences such as natural weather variability or increased greenhouse gas emissions to the stratosphere.

“There’s been a lot of qualitative evidence showing that the Antarctic ozone hole is getting better. This is really the first study that has quantified confidence in the recovery of the ozone hole,” says study author Susan Solomon, the Lee and Geraldine Martin Professor of Environmental Studies and Chemistry. “The conclusion is, with 95% confidence, it is recovering. Which is awesome. And it shows we can actually solve environmental problems.” Continue reading

OnStar Starts Voice Application Student Competition

OnStar is looking for new in-vehicle voice-enabled applications through a contest at five U.S. universities.

The growing telematics subsidiary of General Motors is a leader in the controversial area of in-vehicle electronics OnStar is interested in working with students who are studying voice application development. The voice platform allows OnStar to provide more connectivity to subscribers.

This also might enable more distracted driving accidents, currently responsible for 6,000 deaths and more than 500,000 serious injuries each year, according to the latest National Highway Traffic Safety Administration statistics. A total of 33,808 people lost their lives in motor vehicle crashes in 2009. Another 2.22 million people were injured. Continue reading
