Mirror, Mirror on the Wall: Why These Cells Could Spell Doom for Us All

But there’s no reason that mirrored versions of these building blocks can’t exist, and indeed, many are found in nature. Although almost all amino acids are left-handed, right-handed amino acids D-alanine, D-methionine and D-leucine (the D prefix comes from the Latin dextro, meaning “right”) appear in bacterial cell walls.

Alright, folks, let’s take a little trip to the year 2036. Imagine a world where scientists are whipping up drugs that are like your favorite comfort food, but, you know, in mirror form. These medications are designed to be mirror-image versions of the molecules your body uses to battle disease. Sounds fancy, right? Their big selling point is that these mirror molecules can last longer in your system because, well, your body’s enzymes don’t recognize them as the enemy. It’s like wearing a disguise to sneak past a bouncer at a club—only, in this case, the bouncer is your immune system.

So, what’s the catch? Well, let’s just say that science sometimes has a flair for the dramatic. The researchers, excited about their mirror magic, decide to enlist engineered mirror bacteria—basically, tiny little factories made of reversed molecules. Think of them as the hipster version of E. coli, but without the bad reputation (at least for now).

Now, picture this: one of the researchers, let’s call her Dr. Forgetful, has a minor cut on her thumb. Instead of being the responsible scientist we all hope she’d be, she skips the gloves and accidentally touches a surface that’s been contaminated with these mischievous mirror cells. Spoiler alert: this is where things start to go south.

Dr. Forgetful’s immune system, which usually has a PhD in identifying intruders, doesn’t recognize these mirror proteins. It’s like sending a cat to catch a mouse that’s dressed up in a dog costume—good luck with that! Instead of kicking the bacteria out, they multiply like rabbits on a dating app. Before you know it, she’s feeling a bit under the weather, and a few days later, she’s in the hospital, bombarded with antibiotics that are about as effective as trying to use a water gun to put out a forest fire. And just like that, she’s gone.

But wait, the plot thickens! While Dr. Forgetful is busy battling her invisible foes, she’s also spreading these mirror bacteria around her house like confetti at a party. Her cat, being the innocent bystander it is, carries some of these cells into the garden. Next thing you know, worms and insects are getting infected, and the bacteria are on a world tour. Her kids unwittingly take them to school—because, of course, kids never stop sharing germs—and soon, more people are falling ill. It’s like a game of telephone, but instead of secrets, it’s deadly bacteria.

Now, you might be thinking this sounds like a plot straight out of a sci-fi flick. But here’s the kicker: this scenario isn’t as far-fetched as it seems. Scientists are making rapid strides in technologies that could allow for the creation of these mirror organisms in the not-so-distant future. We’re talking about biochemists making complex mirror molecules, including enzymes that build mirror RNA, and synthetic biologists who are getting closer to constructing bacterial cells from scratch. It’s like they’re playing God, and we all know how that usually ends in movies.

Just over a year ago, a group of 38 scientists (including yours truly) published a warning in the journal Science, urging a halt to this work. Why? Because the potential catastrophe is real, and unless we hit the brakes, we might just be inviting a disaster of epic proportions.

So, as we move forward into this brave new world of scientific exploration, let’s remember to tread carefully. Mirror cells might sound like the latest trend in health and wellness, but they could also be the evil twins that wipe us out. Who knew that science could be so dramatic? Let’s just hope that Dr. Forgetful’s story serves as a cautionary tale for all of us—because the last thing we need is a global outbreak of mirror bacteria. Yikes!
