Imported from Asia: OZONE
January 21, 2010 06:59 AM - Roger Greenway, ENN

Ever wonder how the western US has high ozone levels when the winds usually blow in off the Pacific Ocean? Did you think it was all from the cars clogging the freeways? Turns out, it is caused in part from emissions of ozone generating air emissions from Asia. A study by the National Oceanic and Atmospheric Administration (NOAA) shows that Springtime ozone levels above western North America are rising, primarily due to air flowing eastward from the Pacific Ocean, a trend that is most significant when the air originates in Asia.

One, of course, is to reduce stress (at least short term). A new study suggests that beer is a significant source of dietary silicon, a key ingredient for increasing bone mineral density. Researchers from the Department of Food Science & Technology at the University of California, Davis studied commercial beer production to determine the relationship between beer production methods and the resulting silicon content, concluding that beer is a rich source of dietary silicon. Details of this study are available in the February issue of the Journal of the Science of Food and Agriculture, published by Wiley-Blackwell on behalf of the Society of Chemical Industry.

Biodiversity loss matters, and communication is crucial

David Dickson, Science and Development Network
Communicating why biodiversity loss matters for people is essential for reversing it. The failed UN climate talks in Copenhagen in December could hardly have been a less promising prelude to the International Year of Biodiversity, which opened last month (January). As with climate change, the threat of large-scale biodiversity loss — and the need for global political action to stop it — is growing every day.
