Michigan Radio's Steve Carmody reports "an oil pipeline that broke near Marshall last month is undergoing a critical pressure test today. Enbridge Energy is flooding the pipeline with water to see if it can withstand the pressure."

If it works, and government inspectors say it's o.k., the pipeline will be restarted.

Ozone way up in the atmosphere... good. Ozone near the ground... bad. 

SEMCOG (Southeast Michigan Council of Governments) says the air outside could be unhealthy today.  The group says "elements have been in place for a few days now – sunny skies, hot temperatures, and southerly winds. Admittedly this is beautiful weather, but the ongoing nature of these conditions is compromising our air quality and enabling ground-level ozone to remain high."

There's been a lot of talk recently about how quickly microbes in the Gulf have been gobbling up the spill oil.  Scientific American has a report on what researchers know about the microbes in the Gulf. Reporter David Biello reports "the microbes of the deep Gulf of Mexico were ready to handle an oil spill."
