DBS faculty share some GOOD news about UM with Missoula community
A guest opinion column signed by all DBS faculty appeared in the today's (3/15/17) Missoulian. While acknowledging that UM and every program within it faces significant challenges at this time, the column emphasizes a reality that Biology students and faculty experience daily -- "the quality of our faculty and the education we give our students have never been better".

Legs as gills, guts as heart: plumbing the secrets of sea spiders
Sea spiders (image: Tim Dwyer) grow to Frisbee-size in the frigid waters of the Antarctic, using pores on the surface of their long legs to "breathe" in this oxygen-poor environment. But how the sea spiders circulate that oxygen was mysterious, as they lack a strong heart and advanced circulatory system. OBEE Assoc. Prof. Art Woods and colleagues made a splash recently by reporting that the guts of sea spiders (uniquely) double as auxiliary hearts, with the movement of food washing blood throughout their bodies. Read more about the study in Science News, more about sea spiders and polar gigantism here. For the inside scoop on the joy of science under Antarctic ice, check out this recent interview of Art in Outside Magazine. More DBS News.
