Polar bears have always been mysterious creatures, but now, with a new tracking and observation method, scientists will be able to find out more about their habits.
Anthony Pagano, a wildlife biologist with the U.S. Geological Survey, has been testing accelerometers on the collars of tracked polar bears. Accelerometers measure acceleration forces that can be either static (due to gravity) or, in this case, dynamic (due to movement or vibrations). It's basically a Fitbit for polar bears, the New York Times said.
Now, instead of just a tracking device, polar bear collars will be fitted with an accelerometer and a camera. With data from both of the new devices, scientists can link certain acceleration and movement with activities like walking, swimming, eating or playing.
All the polar bears Pagano is tracking are females because "the necks of males are wider than their heads, so the collars won't stay on," according to the Times.
This experiment has captured some never-before-seen footage of polar bear life. A life that is rapidly being changed due to climate change.

EPA Watchdog: White House Blocked Part of Truck Pollution Investigation, Caused Lack of Public Information
The Trump administration pushed through an exemption to clean air rules, effectively freeing heavy polluting, super-cargo trucks from following clean air rules. It rushed the rule without conducting a federally mandated study on how it would impact public health, especially children, said the Environmental Protection Agency (EPA) Inspector General Charles J. Sheehan in a report released yesterday, as the AP reported.
