Why it matters: This sensing and other highly specialized behavior can reveal different information about the brain than studies done in rats, mice and other laboratory model animals.
Expanding Antarctic ambitions, coupled with the impact of the pandemic and geopolitics, are reshaping science at the planet's southern pole.
Why it matters: Scientific research has for decades guided the governance of Antarctica, offering access to scientific frontiers and a say in the course of the continent. But as countries grow their presence on Antarctica, a wider range of politics and goals is intersecting with polar science.
