3-D CT scans give the U a leg up in spotting veterinary injuries

When Gauge fell from a rooftop a few months ago, he had two strikes against him:

• The ground was five stories down

• He was a dog, not a cat

Rushed to the University of Minnesota Veterinary Medical Center, Gauge looked like a goner. Even after his internal injuries were tended to, his fractured pelvis loomed like a third strike that would hobble him for life. That’s what it’s like for too many animals, whose veterinary surgeons have only conventional X-rays or a stack of two-dimensional CT scans to guide them as they go into surgery. (more…)

Jay Dickson and Jim Head have gathered time-lapse photography and other data about the sustained salinity of Antarctica’s Don Juan Pond, the most saline natural body of water on earth. Their findings, published online in Scientific Reports, suggest that such ponds could be possible on Mars.

PROVIDENCE, R.I. [Brown University] — Antarctica’s Don Juan Pond might be the unlikeliest body of water on Earth. Situated in the frigid McMurdo Dry Valleys, only the pond’s high salt content — by far the highest of any body of water on the planet — keeps it from freezing into oblivion. (more…)
