It has been estimated that by 2030, even if all existing mines continue at their normal rate of production, there still will be barely enough metal to satisfy half of global demand.

Polar bears begin living in abandoned buildings in a remote island.

Kokh’s photos are a welcome sight, as we’re often shown images of polar bears who are struggling. But here, we are able to see these incredible creatures lounging on the grass or peering out from windows to see what Kokh is up to. This thrilling opportunity to see the polar bears is something that Kokh will not soon forget. He and his traveling companions covered over 1,200 miles of the coast in a sailboat, exploring the untouched landscape.

Their original destination to photograph polar bears—Wrangle Island—turned out to be a bust. Though the island is famous for its bears, they simply weren’t there when the adventurers landed. Instead, they were treated to something that was perhaps better—and certainly more unexpected.

“Nature always sends you something when you least expect it,” Kokh tells My Modern Met. “When we passed through the Kolyuchin Island near the Northern coast of Chukotka, we saw some movements in the windows of the abandoned houses. And when we got close—those were bears! Never before they were seen in those buildings, so that was a once in a lifetime situation.”

Researchers have developed an alternative positioning system that is more robust and accurate than GPS, especially in urban settings.

An alternative positioning system that is more robust and accurate than GPS, especially in urban settings has been developed by researchers of Delft University of Technology, Vrije Universiteit Amsterdam, and VSL. The working prototype that demonstrated this new mobile network infrastructure achieved an accuracy.

The new alternative positioning system could achieve an accuracy of 10 centimeters.

Researchers have created an alternative positioning system that is more accurate and robust than GPS. The team discovered that the alternative positioning system is more accurate within urban settings. The prototype that demonstrated this new mobile network infrastructure was able to achieve an accuracy of 10 centimeters.

The results from the study were published in the journal Nature. University of Technology/tudelft.nl.
