- 'Combinatorial' approach squashes software bugs faster, cheaper
12-12-2007 · EurekAlert!
NIST software researchers, working with the University of Texas, are developing an open-source tool that uses an emerging approach called 'combinatorial testing' to catch programming errors. The NIST tool could save software developers significant time and money when it is released next year.

- November GEOLOGY and GSA TODAY Media Highlights
11-05-2007 · EurekAlert!
Topics include: continental deformation and the San Andreas fault; interior heating of Mars; correlation of 200-million-year-old rocks between Britain and America; environmental stress and the end-Permian and end-Triassic mass extinctions; rock weathering in Canada's Mackenzie River basin as a CO2 source rather than sink; how stable continents split in the absence of active volcanism; and geologic evolution of Alaska and the northern Pacific Rim. The GSA TODAY science article explores conceptual uncertainty in geoscience interpretation.

- Hair untangles woolly mammoth puzzle
09-27-2007 · EurekAlert!
New research reveals that hair shafts provide an ideal source of ancient DNA -- a better source than bones and muscle for studying the genome sequences of extinct animals. The researchers' efficient methods yielded entire mitochondrial genomes from 10 woolly mammoths -- more such genomes of extinct animals than previously had been published. The research opens the door to obtaining mitochondrial genome sequences from other extinct species and to understanding how species of large mammals can go extinct.
