San Diego, California - A study released this week (Sept. 12, 2016) is shedding new light on how scientists evaluate polar bear diet and weight loss during their fasting season. On average, a polar bear loses up to 30 percent of its total body mass while fasting during the open-water season. Although some scientists previously believed land-based foods could supplement the bears’ nutritional needs until the sea ice returns, a new study by San Diego Zoo Global conservationists published in the scientific journal Physiological and Biochemical Zoology has revealed that access to terrestrial food is not sufficient to reduce the rate of body mass loss for fasting polar bears.

Washington, DC - If you’ve ever used a device that picks up signals over the air, you know that sometimes you just can’t get the signal to come in clearly. You point the device every which way, move it all around the room, do a little dance, but nothing seems to work. There doesn’t seem to be any explanation. Maybe it’s sunspots, who knows? While that’s an annoyance for us, sometimes people’s lives depend on that signal getting through. People like firefighters. One of my group’s more recent projects has been to help make sure that their signals get through, wherever they are.
