The concerns, legitimate or otherwise, about genetically modified foods such as Monsanto's Round-up Ready soy-beans, may be causing unintended consequences
This is all wrong and mistaken.
The concerns are legitimate. Look into "gliadin" if you do not already know. That was a product of 1976 mutagenesis experiments. People who eat it consume an additional 400 calories every day. It's popular with the food industry and it is why many people are fat.
The unintended consequences are the result of lax anti-GM regulations. Mutagenesis is Genetic Modification (GM). The problem is not that the "backlash" against transgenic Cauliflower Mosaic Virus vectors has pushed people to these crude methods, the problems are multiple and are as follows:
#1. that mutagenesis has ever been legal and has already been used to produce GM food.
#2. that gliadin-enhanced food is legal
#3. that glyphosphate (Roundup) is legal
#4. that glyphosphate-resistant crops are made via Cauliflower Mosaic Virus transgenic infection is legal.
#5. that any person who speaks English would write one word in favor of the hubris of Man and the obscure mutation of nature.
Hail to the misinformed who think agricultural mutagenesis has benefited humanity. You need to re-learn.
As the photons enter the cloud of cold atoms, Lukin said, its energy excites atoms along its path, causing the photon to slow dramatically. As the photon moves through the cloud, that energy is handed off from atom to atom, and eventually exits the cloud with the photon.
These are not photons in free space being described. These are photons which have excited electron orbitals in some material.
If you can't understand it, it is intuitively obvious.
