Can a research ban save us?
Five years after Covid-19, declared a global pandemic
Tuesday marks the five years since the start of the Covid-19 pandemic. On this day in 2020, the World Health Organization declared a global pandemic, causing lockdowns around the world.

Kate Adamara was dealing with something dangerous.
In her synthetic biology lab, Adamara had given one important twist and took preliminary steps to create live cells from scratch. Changing these molecules creates an unnatural mirror image of a different cell, just like the left.
This effort is not only an attractive research challenge, but can also be used to improve biotechnology and medicine. However, when Adamala and her colleagues spoke with bi-security experts about the project, serious concerns began brewing.
“They started asking questions like, ‘Have you ever considered what happens if that cell is released or if it infects a human?'” said Adamala, an associate professor at the University of Minnesota. They didn’t have it.
Therefore, researchers have gathered dozens of experts from various fields around the world, including two Nobel Prize winners who have worked for months to determine the risks of creating so-called “mirror life” and the likelihood that those risks could be alleviated. Ultimately, they concluded that mirror cells could cause “unprecedented and irreversible harm” to our world.
“We cannot rule out scenarios in which mirror bacteria act as invasive species across many ecosystems. Scientists wrote in a paper published in Science Journal Science in December along with a 299-page technical report.
Vaughn Cooper, a co-author who is a professor at the University of Pittsburgh, said that studying how bacteria adapt to new environments is difficult to overstate the threats that mirror life could pose if the world doesn’t unite to ban further research.
“Mirror cells pose a level of threat that is far beyond what has previously existed on this planet. “And the risk of building a biosafety mechanism to control it is simply unworthy.”
What is Mirror Life?
Every known building block of life has a property known as chirality in one of two specific orientations. For example, DNA is made up of “right-handed” components called nucleotides, and proteins are made from “left-handed” amino acids.
In mirror cells, the chirality of these molecules is reversed. In theory, researchers said mirror cells could live and grow just like ours.
How Mirror Life can become an existential threat
Adamala said part of the motivation for creating mirror cells is that they do not interact with the world in the same way as natural cells. That’s what puts them in danger as well.
For example, Adamala said that treatments using cells can cause unwanted responses in a patient’s immune system, and at the same time can lead to illness while curing the underlying disease. It does not happen with treatments using mirror cells, as our immune system does not recognize them and attack them.
But that also means that mirror cells can replicate unchecked within our bodies, causing a fatal infection that can progress rapidly without causing our defense system, Cooper said.
“For example, if this is built and someone accidentally infected, it’s plausible that they probably go home and don’t know they’ve been infected for a while while this group is growing,” he said.
Mirror Cells can wreak havoc in our environment if they escape from the lab. Even if the initial mirror cells were “a bit weakened,” Cooper said there was an incredible competitive advantage over other bacteria, as there were no natural predators.
Cooper initially thought that mirror bacteria would eventually die due to food shortages, but there are enough molecules that are not right-handed or left-handed to maintain them. Labs that use dangerous substances generally have strict containment procedures, but they are not unreturnable and are too likely to escape, Cooper said.
A research ban has reached, but new laws were needed
Cooper said it is still impossible to construct cells from mirrors and the like, but researchers began the process by synthesizing mirror proteins and enzymes. He and his colleagues estimated that, given them sufficient resources and talent, scientists could create a complete mirror bacteria within ten years.
But for now, the world may be safe from mirror cells. Adamala said that almost everyone in the small scientific community interested in developing these cells agrees that this is not the case as a result of their discoveries.
The paper urged nearly 100 scientists and ethicists to gather in Paris in June, further debating the risks of creating mirror creatures. According to the institution that hosted the event, many people feel that self-regulation alone is not enough, and researchers are discussing the next steps to meet again in Manchester, the UK and Singapore.
“The risks are so high that I don’t think we should do this kind of job,” said Jorg Hoheisel, honorary director of the German Cancer Research Centre, who attended a conference in Paris.
Adamala said he wanted to see the creation of a treaty banning the development of mirror cells around the world, as well as the United Nations Bioweapons Treaty. She believes that is unlikely because of the political challenge of passing international law, but she hopes that individual countries and research funders agree to abandon their pursuit of mirror life.
“This is a really good time to talk about it because you can actually stop it before it happens,” she said. “This is a very rare and unusual opportunity to mitigate the risks we don’t actually have at our doorstep.”
