Brief Bio

I was born and raised in Kalamazoo MI. I earned my bachelors of science in biology from Western Michigan University. I met and fell in love with a big goof of a man named Cliff. I have a fat lazy cat named Kerby and a dog named Bear.

Hot springs microbes hold key to dating sedimentary rocks

January 23rd, 2008 at 10:18 am (Geology, Microbiology)

From Physorg.com, an example of biogeochemistry where microorganisms contribute to the deposition of sediments. Looking at Angel Terrace in Yellowstone National Park, the rate of precipitation of calcium carbonate (CaCO3) was reduced when there was not microbes. So depending on the layers of limestone, the age of the rock can be determined. Also, the microbes seem to create a pattern in the calcium carbonate crystals.

From EurekaAlert.com, this show the subtle way that changes in form can occur. By mucking about with a gene that regulates limb growth, scientists have created mice with long fore limbs.
