An Arctic Fox Has Been Tracked Walking 2,700 Miles From Norway All The Way to Canada

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?”

Giant Floating Solar Farms Could Make Fuel and Help Solve the Climate Crisis, Says Study

Millions of solar panels clustered together to form an island could convert carbon dioxide in seawater into methanol, which can fuel airplanes and trucks, according to new research from Norway and Switzerland and published in the Proceedings of the National Academy of Sciences journal, PNAS, as NBC News reported. The floating islands could drastically reduce greenhouse gas emissions and dependence on fossil fuels.

Scientists succeed in mapping every neuron in a worm, a breakthrough in neuroscience

In a way, the connectome is also a foundation for understanding far more complex nervous systems like our own.

“If a worm can do so much with so few neurons, and we have orders of magnitude more neurons,” Paul Sternberg, a biology professor at the California Institute of Technology in Pasadena, told Scientific American, “then we’re amazing.”

The datasets that were generated from and analysed in the current study are available at wormwiring.org
