Scientists attached cameras to polar bears

We often imagine polar bears as the rulers of the frozen north—fearsome, solitary figures pacing confidently across vast expanses of ice. But when researchers recently strapped tiny cameras to the necks of twenty polar bears in Canada’s Hudson Bay, they captured something unexpected, and heartbreaking: not power, but struggle.

These never-before-seen recordings offer an intimate glimpse into the lives of these Arctic giants as they navigate a landscape that’s quite literally melting beneath their feet. The footage, taken over three years, paints a stark portrait of an animal forced to adapt—and failing to thrive—in a world that no longer fits its needs.

They drove 2,500 km in an electric car and reached a blunt verdict: diesel still rules the road

They drove 2,500 km in an electric car

The plan was ambitious: drive more than 2,500 kilometres from Berlin to Madrid in a pair of electric vehicles—one Tesla Model Y and one Tesla Model 3—both kitted out in their Long Range versions. Two sleek cars, fully charged and ready to take on the open road.

The goal wasn’t just to get from A to B. It was to see whether an electric road trip across Europe was as efficient, cost-effective and seamless as it’s often made out to be. Could electricity outpace petrol—or more pointedly, diesel—on long-distance journeys?

The route was largely mapped out by Tesla’s own trip planner, which naturally nudged drivers toward its network of Superchargers. Every 200 to 300 kilometres came a pit stop—not just to plug in, but also to stretch legs, grab a coffee, and yes, queue for the loo. Often, the car was ready to go before the driver was.
