New evidence that plants get their energy using quantum entanglement

Biophysicists theorize that plants tap into the eerie world of quantum entanglement during photosynthesis. But the evidence to date has been purely circumstantial. Now, scientists have discovered a feature of plants that cannot be explained by classical physics alone — but which quantum mechanics answers quite nicely.

The fact that biological systems can exploit quantum effects is quite astounding. In a way, they’re like mini-quantum computers capable of scanning all possible options in order to choose the most efficient paths or solutions. For plants, this means the ability to make the most of the energy they receive and then deliver that energy from leaves with near perfect efficiency.

Good Vibrations

But for this to work, plants require the capacity to work in harmony with the wild, wacky, and extremely small world of quantum phenomena. The going theory is that plants have light-gathering macromolecules in their cells that can transfer energy via molecular vibrations — vibrations that have no equivalents in classical physics. Most of these light-gathering macromolecules are comprised of chromophores attached to proteins. These macromolecules carry out the first step of photosynthesis by capturing sunlight and efficiently transferring the energy.

Previous inquiries suggested that this energy is transferred in a wave-like manner, but it was a process that could still be explained by classical physics.

In Perfect Quantum Harmony

In the new study, however, UCL researchers identified a specific feature in biological systems that can only be predicted by quantum physics. The team learned that the energy transfer in the light-harvesting macromolecules is facilitated by specific vibrational motions of the chromophores.

"We found that the properties of some of the chromophore vibrations that assist energy transfer during photosynthesis can never be described with classical laws, and moreover, this non-classical behaviour enhances the efficiency of the energy transfer," noted supervisor and co-author Alexandra Olaya-Castro in a statement.

The vibrations in question are periodic motions of the atoms within a molecule. It’s similar to how an object moves when it’s attached to a spring. Sometimes, the energy of two vibrating chromophores match the energy difference between the electronic transitions of chromophores. The result is a coherent exchange of a single quantum of energy.

Democratic National Committee Chair Wasserman Schultz Can’t Explain Difference Between Democrat Party and Socialism

Things got very awkward today when Chris Matthews asked DNC Chair Debbie Wasserman Schultz what the difference was between the modern Democratic Party and Socialism. We haven’t seen that dazed look since Rachel Dolezal was busted as a fraud. Wasserman Schultz was speechless. Completely stumped. Couldn’t answer. Then changed the subject. Because we all know there is no difference between today’s Democrat Party and the radical ...
Catching on slow: Yet Another Study Show Cellphone Radiation Cause Cancer

The scientists were right — your cell phone can give you cancer. There have long been whispers of a cancer connection from your cell — and a new study backs up the claims. "These data are a clear sign of the real risks this kind of radiation poses for human health," study author Igor Yakymenko said. Yakymenko’s meta-study — basically a study of ...

For weeks, the media have trumpeted the supposed death of the Trump campaign. First, they claimed, Trump’s campaign imploded on launch thanks to his comments about illegal immigration. Then they claimed that Trump was finished because of his slap at Senator’s (R-AZ) war service. But neither of those comments alienated Trump’s base – he’s maintained his seven point lead over ...
