Today’s Most Popular: Recent Findings Hints Quantum Physics Binds DNA

Dna_fragment In what would be a potentially explosive finding, a team of scientists at the National University of Singapore suggested that it is quantum entanglement that holds our DNA together.

In quantum entanglement, two objects are connected by an invisible wave that allows them to essentially share the same existence. If something happens to one object, it immediately happens to the other, regardless of their apart.

Elisabeth Rieper and colleagues at the National University of Singapore say this entanglement might hold the DNA double helix together.


According to MIT's Technology Review, Rieper and colleagues used a theoretical model of DNA in which each nucleotide consists of electrons orbiting a positively charged nucleus. The movement of the negative cloud is a harmonic oscillator. When the nucleotides bond to form a base pair, the clouds must oscillate in opposite directions or the structure won't be stable. Rieper and colleagues asked what would happen to those oscillations when the base pairs are stacked in a double helix.

The helix should vibrate and fall apart, but it doesn't because the oscillations occur as a superposition of states — meaning they oscillate in all possible states at once. A quantum entanglement that effectively holds it all together.

Rieper and colleages say that in a standard analysis, there's not enough energy to hold DNA together, but their quantum theory makes it work. Proof will have to follow to confirm their theory.
