Interesting. When you tie this into other research which shows, for example, that our gut bacteria may control parts of our immune system and influence our brains it gets down right to who/what are we really and how separate an entity are we from each other? Can the bacteria on and in each of us communicate with bacteria on and in others of us? http://www.sciencedaily.com/releases/2011/02/110201083928.htm http://www.medmicro.wisc.edu/graduate/courses/900/archive/2005/pdf/Mazmanian11182005.pdf

Looking backward, can anyone name a physical phenomenon that Nature has not employed in an organism...electric eels, radar bats, sonar dolphins, magnetic or celestial navigating whales or birds, chemical warfare spewing bread molds, humans walking around with organic computers and integrated heads-up displays. The real question is are bacterial FM or AM...

With human nerves using small currents to function, of course, we must have some sort of electromagnetic signatures. Ahh.. Bio-electronics is so fascinating..

There is nothing especially new about this hypothesis, except that it's now coming from a university researcher here in the US. If you search using keywords like "DNA biocomputer" or "microtubules waveguides" or "biophotons" you can read articles as interesting as these two, both dating from many years ago. Related to this, I found "The Rainbow and the Worm" to be a useful book about coherence in nature. http://www.laserponcture.net/anglais/gariaev.pdf http://www.maik.ru/full/lasphys/96/6/lasphys6_96p1211full.pdf http://www.i-sis.org.uk/rnbwwrm.php

good news for humans then. We can also use ourselves as radio wave source to communicate with each other [pun intended]. Hopefully we get rid of the pain to learn different languages.

"Theoretical physicists have proposed an explanation for how bacteria might transmit electromagnetic signals: Chromosomes could act like antennae, with electrons traveling gene circuits to produce species-specific wavelengths. "It’s just a hypothesis, and the notion that bacteria can generate radio waves is controversial. But according to Northeastern University physicist Allan Widom, calculations based on the properties of DNA and electrons square with what’s been measured." http://www.wired.com/wiredscience/2011/04/bacterial-radio/

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
