Scientists Just Discovered Something That Could Rewrite Biology

And It's Not What You Think

One of the biggest mysteries in science, and honestly life, is something called homochirality and it's about to become very relevant to all of us.

Here's the deal:

Back in 1841, Louis Pasteur discovered something curious about molecules. They can be "chiral," which basically means they come in left-handed and right-handed versions - like your hands. The compound looks exactly the same in structure, but are mirror images that can't be stacked on top of each other.

Many compounds we know are chiral - for example, lactose, the sugar found in milk, is chiral. But here’s the fascinating part. While either version can be synthesized, the version made and consumed by us is always the right-handed version. In fact, as far as we know, life only uses only right-handed sugars, which is why the DNA helix always twists to the right. But, why this “homochirality” happens is one of the biggest to unlocking the origins of life.
