IVALO, Finland—In 1987, fictional superspy James Bond careened around a frozen lake in an Aston Martin in the movie The Living Daylights . Bond’s tires were carrying a secret—retractable tire studs that operated with the touch of a button. After cutting a circle in the ice with a wheel to sink the bad guys, Bond deployed his outriggers for balance and his on-demand studs for an impressive getaway.

Nokian Tires played with that idea, presenting a concept in 2014 with similar functionality. However, as Nokian development manager Mikko Liukkula remembers wryly, each tire was so complex that a production set would have cost more than the vehicle itself. Fast-forward to 2026, and Nokian has debuted a giant step forward in studded-tire engineering: a studded winter tire that automatically adjusts to changes in temperature and surface pressure.

I put these new Hakkapeliitta 01 tires through the wringer in and around a frozen-over Lake Tammijärvi at Nokian’s 1,700-acre testing center. After drifting, slaloming, hard braking, and swooshing along snowy trails, I can attest to the quality of the gripping power.

Amazon’s ecommerce business has summoned a large group of engineers to a meeting on Tuesday for a “deep dive” into a spate of outages, including incidents tied to the use of AI coding tools.

The online retail giant said there had been a “trend of incidents” in recent months, characterized by a “high blast radius” and “Gen-AI assisted changes” among other factors, according to a briefing note for the meeting seen by the FT.

Under “contributing factors” the note included “novel GenAI usage for which best practices and safeguards are not yet fully established.”

In 1774, British physician-scientist Charles Blagden received an unusual invitation from a fellow physician: to spend time in a small room that was hotter, he wrote, “than it was formerly thought any living creature could bear.”

Many people may have been appalled by this offer, but Blagden was delighted by the opportunity for self-experimentation. He marveled as his own temperature remained at 98° Fahrenheit (approximately 37° Celsius), even as the temperature of the room approached 200°F (about 93°C).

Today, this ability to maintain a stable body temperature—called homeothermy—is known to exist among myriad species of mammals and birds. But there are also some notable exceptions. The body temperature of the fat-tailed dwarf lemur, for example, can fluctuate by nearly 45°F (25°C) over a single day.
