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?
Cheung, who regularly expresses hostility toward reporters on social media platform X, asserted in a Friday night post that, “some reporters have been caught” taking pictures of sensitive information and “eavesdropping on private, closed-door meetings.”

That claim came as news to White House press corps leaders, who are not aware of colleagues being “caught.”

Early in Bill Clinton’s presidency, Clinton aides similarly attempted to bar journalists from the “upper press” area, causing an outcry. That ban was rescinded.

Journalists had normal access to the offices during President Trump’s first term in office. But in his second term, Trump and his aides have taken several steps to stymie news coverage and circumvent traditional media outlets.

Last winter, the administration blocked the Associated Press from attending some White House events, leading to a First Amendment lawsuit that is still working its way through the courts.

The administration has also stopped publishing transcripts of Trump’s remarks; has taken control of daily press pool assignments; and has invited fawning pro-Trump commentators to presidential Q&As.

Some cabinet secretaries have followed Trump’s lead. Last month, Defense Secretary Pete Hegseth implemented severe new restrictions for Pentagon press pass credentialing, leading virtually every major media outlet to reject the rules and give up access to the Pentagon complex.
