From the worst wildfires to water shortages in cities.

At first, the scientists wondered whether it was a mistake.

Just 21 days after leaving the Norwegian island of Spitsbergen, an arctic fox had arrived in Greenland. And in less than three months, it made it to Canada. The fox averaged nearly 30 miles a day (50 kilometers) — some days, though, it walked almost 100 (160 kilometers).

“When it started happening, we thought ‘is this really true?’” said Arnaud Tarroux, one of the researchers who tracked the female fox. Was there “an error in the data?”

New research into the experience of pain challenges previous beliefs about how quickly pain signals travel in humans compared with touch signals.

During winter time, some snapping turtles like to hibernate in ponds and lakes. Safely tucked away underneath a thin layer of ice, these freshwater reptiles can survive up to six months without any oxygen to speak of.

How their bodies can cope with this depends on the way they were raised, it turns out. New research has revealed that when turtle embryos are exposed to low levels of oxygen, it programs their hearts to be more resilient to such conditions for the rest of their lives.

From the very start of their existence, it appears these incredible creatures are primed for a life of aquatic hypoxia. Developing in nests deep beneath the water, their embryos can sometimes be subject to as little as 11 percent oxygen, and this can permanently alter their cardiac structure and function.
