What is mirror life? Scientists are sounding the alarm

Военный адвокат Запорожье
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?

Ukrainian President Volodymyr Zelensky condemned Russian attacks on the Ukrainian regions of Kharkiv, Zaporizhzhia and Sumy on Monday, saying that the Kremlin intends to “humiliate diplomatic efforts” just hours before European leaders visit the White House.

“The Russian war machine continues to destroy lives despite everything,” Zelensky said in a statement, hours before he’s due to meet US President Donald Trump in the Oval Office. “That is precisely why we are seeking assistance to put an end to the killings. That is why reliable security guarantees are required. That is why Russia should not be rewarded for its participation in this war.”

“Everyone seeks dignified peace and true security,” the Ukrainian president said. “And at this very moment, the Russians are attacking Kharkiv, Zaporizhzhia, the Sumy region, and Odesa, destroying residential buildings and our civilian infrastructure.”

At least seven people were killed in Russia’s attack? on Kharkiv and a further three killed in the ballistic missile strike on the city of Zaporizhzhia, with scores more injured, according to Ukrainian authorities.

“This was a demonstrative and cynical Russian strike,” Zelensky added.

The directives largely roll back efforts made over the last decade attempting to eradicate toxic culture in the military, both to decrease harmful behaviors like harassment, but also to meet practical needs of getting people in uniform and keeping them there longer as the military branches faced years of struggles filling the ranks.

Many major reforms were described by the officials who implemented them as driven by that need; when former Defense Secretary Ash Carter opened up combat roles to women in 2015, he said the military “cannot afford to cut ourselves off from half the country’s talents and skills” if it wanted to succeed in national defense.

And while the military had made changes in recent years in an attempt to lessen instances of harassment, discrimination or toxic leadership by creating reporting mechanisms so that troops would come forward, Hegseth said those efforts went too far and were undercutting commanders.

“The definition of ‘toxic’ has been turned upside down, and we’re correcting that,” Hegseth vowed on Tuesday, adding that the Defense Department would be undertaking a review of words like “hazing” and “bullying” which he said had been “weaponized.”
