This is of course what I have been busily doing since the beginning of 2005. I have developed detailed model of quantum biology based on dark matter phases realized as a hierarchy with levels labeled by values of Planck constant (see the series of articles here and various books about TGD inspired quantum biology). To my great astonishment, Sean Carroll forgets to mention my work in his speculations although he certainly knows it since I have visited many times in his blog and other blogs that Sean himself has visited. Maybe Sean should become a little bit worried: this kind of memory defects are not good in this profession.
I am afraid that this kind of selective amnesia might infect also other theoreticians visiting in blogs and I must ask myself whether something is wrong with me. Could it be that it is my blog and the blogs that I have visited which spread the disease? Since this might be the case, I must give a general warning. I have visited many blogs during weekend and talked about CDF anomaly. There have been a lot of visitors since this might be the discovery of century in particle physics. Therefore it could happen that quite many particle theoreticians will suffer similar memory defects in near future as they produce models for CDF anomaly and gradually end up with the "Eureka! Colored leptons!". I am really very sorry if this turns out to be the case.
Below summary Sean Carroll's speculations.
Mysterious dark matter could be shining with its own private kind of light. This "dark radiation" would be invisible to us, but could still have visible effects. Astronomers usually assume that dark matter particles barely interact with each other. Lotty Ackerman and colleagues at Caltech in Pasadena decided to test this assumption by supposing there is a force between dark matter particles that behaves in the same way as the electromagnetic force. That would imply a new form of radiation that is only accessible to dark matter.
Their calculations showed that it could have as much as 1 % of the strength of the electromagnetic force and not conflict with any observations. If the force is close to this strength, its effects might be detectable, as it should affect how dark matter clumps together.
"It might even help with some niggling problems we have now," says team member Sean Carroll. For example, it might explain why there are fewer dwarf galaxies than models predict. Carroll even speculates that more complex dark matter might exist, forming dark matter atoms with their own chemistry – and maybe biology.
Very familiar to me. Except that they have postponed the discovery of the hierarchy of Planck constants, which makes it un-necessary to introduce new gauge groups, which is really something extremely ugly.
