What we're covering
• Zelensky in Washington: European leaders will join Ukrainian President Volodymyr Zelensky at the White House, as he meets with US President Donald Trump this afternoon. Trump said Zelensky must agree to some of Russia’s conditions — including that Ukraine cede Crimea and agree never to join NATO — for the war to end.

• Potential security guarantees: At last week’s summit with Trump, Russian President Vladimir Putin agreed to allow security guarantees for Ukraine and made concessions on “land swaps” as part of a potential peace deal, US envoy Steve Witkoff told CNN. Zelensky suggested that such guarantees would need to be stronger than those that “didn’t work” in the past. Russia has yet to mention such agreements.

• On the ground: Zelensky condemned Russia’s latest strikes across Ukraine, which killed at least 10 people, saying the Kremlin intends to “humiliate diplomatic efforts” and underscores “why reliable security guarantees are required.”

Scientist Kate Adamala doesn’t remember exactly when she realized her lab at the University of Minnesota was working on something potentially dangerous — so dangerous in fact that some researchers think it could pose an existential risk to all life forms on Earth.
She was one of four researchers awarded a $4 million US National Science Foundation grant in 2019 to investigate whether it’s possible to produce a mirror cell, in which the structure of all of its component biomolecules is the reverse of what’s found in normal cells.
The work was important, they thought, because such reversed cells, which have never existed in nature, could shed light on the origins of life and make it easier to create molecules with therapeutic value, potentially tackling significant medical challenges such as infectious disease and superbugs. But doubt crept in.
“It was never one light bulb moment. It was kind of a slow boiling over a few months,” Adamala, a synthetic biologist, said. People started asking questions, she added, “and we thought we can answer them, and then we realized we cannot.”
The questions hinged on what would happen if scientists succeeded in making a “mirror organism” such as a bacterium from molecules that are the mirror images of their natural forms. Could it inadvertently spread unchecked in the body or an environment, posing grave risks to human health and dire consequences for the planet? Or would it merely fizzle out and harmlessly disappear without a trace?
