Inventory of Life
Ricki Lewis | Jul 22, 2001 | 8 min read
The idea sounds audacious: catalog all life on Earth within 25 years, a human generation. The All-Species Inventory hopes to do just that, with private funds and the help of a worldwide network of scientists and nature lovers. "It is a dream, but a neat one," says A. Townsend Peterson, curator of ornithology at the natural history museum and associate professor of ecology and evolutionary biology at the University of Kansas, Lawrence. He is one of 40 scientific advisers to the All-Species effort

BIOREMEDIATION TO THE PIGPEN It was a stinky summer at the EnviroPork hog facility near Larimore, N.D., with penalties pending for violating state odor regulations, and neighbors complaining loudly about the foul fragrance. Making matters worse, the manure lagoon associated with the facility threatened groundwater supplies. Happily, researchers from the University of North Dakota Energy and Environmental Research Center (EERC) had a low-tech solution: barley straw. Using a cannon, they shot a
Cycle Sequencing Kits

When the next time around is always better. Date: July 21, 1997 Comparison Chart DNA sequencing methods have come a long way in 20 years. From the chemical method of Maxam and Gilbert and the dideoxy method of Sanger, DNA sequencing techniques evolved into the "labeling/termination" method that used a modified T7 DNA polymerase such as Sequenase. Propelled by the power and potential of DNA amplification using thermal cycling strategies, earlier DNA sequencing methodologies have increasingly b
