"By means of elaborate organic-chemical synthesis, the team of Münster researchers were able to develop the FlashCaps—a molecule for controlling mRNA translation by means of light. They showed that this strategy effectively inhibits the translation and, after irradiation with light in cells, reactivates it. The difference between this approach and other strategies is not only that the FlashCaps can be used by every laboratory—without any special expertise or special protocols or modifications being necessary—but also that the mRNA, after being irradiated, exists in its natural structure, which makes it easier to study natural processes in cells."

OOL researchers might be interested in how light affects RNA?

Why would this be of any interest to OOL researchers? Do you know what
the eukaryotic 5 prime cap is for mRNA? It is a post transcriptional
modification of the mRNA. Mature mRNA that can be recognized by the
ribosomes and translated into protein have a 5'cap. Light is not needed
for this process.

What these chemical engineers did was to add a modified 5'cap to to
mRNA. The modification is photosensitive so that when light hits the
molecule the addition to the 5'cap is released. The modified 5'cap is
not recognized by the ribosome, but once it releases the modification it
can be recognized.

There isn't anything that relates to the origin of life in this process.

“You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant,” England said."

As a rough approximation, the evidence suggests that's what happened
on Earth after a few billion years. Doesn't that qualify as "long
enough" for you?

OTOH the Bible says God created plants before the Sun. Does that
sound more credible to you?
