(We have daffodils and the ever-fragrant hyacinths in bloom, spinach seedlings showing their faces - and roses budding out like crazy).
It's the road that my brother used to live on in Vermont (he still lives in Vermont, but just down another road).
In tomorrow's issue of the journal Science (29 February 2008), there will be an article titled 'Ubiquity of Biological Ice Nucleators in Snowfall' [Christner et al., Science, Vol. 29(no. 5867):1214]. Here is the abstract from the Science website:
Despite the integral role of ice nucleators (IN) in atmospheric processes leading to precipitation, their sources and distributions have not been well established. We examined IN in snowfall from mid- and high-latitude locations and found that the most active were biological in origin. Of the IN larger than 0.2 micrometer that were active at temperatures warmer than -7°C, 69 to 100% were biological, and a substantial fraction were bacteria. Our results indicate that the biosphere is a source of highly active IN and suggest that these biological particles may affect the precipitation cycle and/or their own precipitation during atmospheric transport.
Ahhh! All of you out there that are tired of the winter's continuing snowfall, might have a bacteria (or two or three) to blame. This is interesting - imagine what it means with respect to transport of bacteria around the globe! Look closely at that snowflake...
