Could glowing salamanders hold the key to long-standing evolutionary questions?

Carleton University Prof. Hillary Maddin in the Department of Earth Sciences wants to find out. Maddin recently acquired four pairs of axolotls, an aquatic salamander species, to assist in research on the evolutionary changes of skull development from the prehistoric era to today.

Pain can be valuable. Without it, we might let our hand linger on a hot stove, for example. But longer-lasting pain, such as the inflammatory pain that can arise after injury, can be debilitating and costly, preventing us from completing important tasks. In natural settings, the lethargy triggered by such pain could even hinder survival. 

A team of researchers has developed a wearable, non-invasive system to monitor electrical activity in the stomach over 24 hours—essentially an electrocardiogram but for the gastro-intestinal (GI) tract.

Take a drive through the countryside near the New Hampshire Seacoast and you might notice a series of tiny rolling hills that look like regularly-spaced ridges. While the repeating pattern may be eye-catching for drivers, and sometimes challenging for bicycle riders, researchers at the University of New Hampshire say they may also hold answers to how glaciers helped form the current terrain and provide insight into the progression of climate change.

NASA's Terra satellite passed over the Arafura Sea and captured an image of newly developed Tropical Cyclone 16P.
