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

Voracious Black Holes Could Feed Alien Life on Rogue Worlds

O.o…

Black holes are engines of destruction on a cosmic scale, but they may also be the bringers of life. New research on supermassive black holes suggests that the radiation they emit during feeding frenzies can create biomolecular building blocks and even power photosynthesis.

The upshot? Far more worlds roaming the Milky Way and beyond could be suitable to life, the researchers speculated.

For their new study, published May 24 in the Astrophysical Journal, scientists created computer models to look at the radiating disks of gas and dust called active galactic nuclei, or AGN, that swirl around supermassive black holes. Some of the brightest objects in the universe, AGN form as a black hole’s gravity binds matter. As that matter swirls around a black hole, it releases incredible amounts of light and radiation.
