&gt; <i>In addition, radioactive decays produce electrons that are slightly more likely to be left-handed.</i><p>Is this a mistake in the article? I was under the impression that all electrons are fundamentally identical to one another.

&gt; They unleashed a pool of random right-handed RNA molecules and let them react in a test tube with left-handed building blocks. They hoped that within that random pool of RNA molecules was a ribozyme capable of stringing the building blocks together.<p>Can someone explain the mechanism behind the origin of that ribozyme from original RNA molecules?

Such a subtle property has such a large impact. One thing that has stuck with me since undergraduate chemistry is that if you take the aspirin molecule and flip its chirality what you end up with is toxic and nothing like aspirin! I miss organic chemistry.

Likely the title of the article changed, and the title here should change with it, as it&#x27;s pretty bad. The new title of the article is &quot;New Twist Found in the Story of Life&#x27;s Start&quot;

Can someone explain the intended meaning of the &quot;handshake&quot; in the photo accompanying the article?

I have a silly question: how is it determined which side is up and down?
