The ancient gray wolves that once roamed the icy expanses of Alaska represented a specialized form that apparently died out along with other big animals at the end of the Pleistocene, many thousands of years ago, researchers report online on June 21st in the journal Current Biology, a publication of Cell Press.

    The extinction of many large mammals at the end of the Ice Age may have packed an even bigger punch than scientists have realized. To the list of victims such as woolly mammoths and saber-toothed cats, a Smithsonian-led team of scientists has added one more: a highly carnivorous form of wolf that lived in Alaska, north of the ice sheets.

  5. Shrinking ponds signal warmer, dryer Alaska
    10-12-2006 · EurekAlert!
    A first-of-its kind analysis of 50 years of remotely sensed imagery from the 1950s to 2002 shows a dramatic reduction in the size and number of more than 10,000 ponds in Alaska. The analysis, by University of Alaska Fairbanks scientists and published this week in the Journal of Geophysical Research, indicates that these landscape-level changes in arctic ponds are associated with recent climate warming in Alaska and may have profound effects on climate and wildlife.

    A team of researchers has identified a new genetic mutation responsible for osteogenesis imperfecta (OI), a condition that makes bones much more likely to break, according to a study published today in the journal Cell. Victims may experience just a few fractures in a lifetime or several hundred beginning before birth. The number of Americans affected is unknown, but estimates range from 20,000 to 50,000.
