What is mirror life? Scientists are sounding the alarm

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?

He has had more cordial, more productive, meetings with US President Donald Trump since that now-notorious encounter on February 28.

But for Ukrainian President Volodymyr Zelensky, today’s meeting at the White House will surely trigger awkward memories of that very public clash with the US President almost six months ago. Navigating the treacherous waters in which he finds himself today will be no easier.

Increasingly, it appears likely he will be told to give up land in exchange for some sort of security guarantees.

The land side of that “deal” will be obvious. It can be drawn on a map. Crimea: gone, says Trump. Donetsk: give all of it up, says Putin, apparently with Trump’s blessing.

But the security guarantees? That’s where far more challenging ideas, like credibility, come into play. Could Zelensky rely on the US to deliver on some NATO Article 5-type promise, to defend Ukraine if Russia breaches any peace agreement?

Putin himself might even see an opportunity to further weaken the West, by testing any such guarantees, confident they are a bluff he could call. But all that would be for the future.

For now, it looks like Zelensky will have to weigh up whether he could bring his country with him if he were to cede territory to Russia – some of it still in Ukrainian hands – or whether he and his people could bear the costs of potentially defying Trump a Nobel Peace Prize, and say no.

If he chose the latter, would the US President immediately end all remaining American support for Ukraine, in terms of military aid and intelligence sharing, for instance?

If that happened, to what extent could Zelensky’s European allies really step in and fill in the gaps left by any full US retreat?

It is an almost impossibly hard choice before him.
