A University of Florida researcher has described a new genus and species of extinct saber-toothed cat from Polk County, Fla., based on additional fossil acquisitions of the animal over the last 25 years.

Collaborators from Mayo-Illinois Alliance for Technology Based Healthcare have developed a new, single molecule test for detecting methylated DNA. Methylation -- the addition of a methyl group of molecules to a DNA strand -- is one of the ways gene expression is regulated. The findings appear in the current issue of Scientific Reports (Nature Publishing Group).
