Zelenskyy in London, Canadian expedition to Antarctica, Latvia loves 'Flow', and more

Ukrainian president Volodymyr Zelenskyy is searching for calmer waters across the pond - one day after a heated confrontation with U.S. President Donald Trump and Vice President JD Vance in the Oval Office. By contrast, a meeting with Britain's Prime Minister Saturday was cordial and supportive. And comes just ahead of a European summit looking at Ukraine's future after three brutal years of war.

Also: A Canadian Navy vessel has reached Antarctica. Now, the team of scientists on board is getting down to work to better understand how climate change has altered the Southern Ocean. You'll hear from CBC's International Climate Correspondent, who's onboard the ship.

And: The Latvian animated movie 'Flow' could soon take home Oscar gold. Its the first movie from the Baltic country to ever be up for an Academy Award. We'll take you to Riga...where Latvians are celebrating the film as a source of national pride.
