Pretty cool Sylvie...can't wait to get one of those bilogical computers...ideally if it could eat my food waste to generate energy for its own operation that would be fantastic ;-)...Kris

This is seriously mind boggling. I want to know how they got into a room together and decided that their next project should be building a computer based on soldier crabs. seriously? Have all of the other mysteries of science been solved?

This could be a great new idea but will it be possible to have it in a miniaturized form as small as today's electronic circuits?

Researchers have been thinking about such biological computers for some time now. Except for niche applications, such computers have serious issues to do with dependability, generalisability, and scalability.

You may scoff but we really have no idea how a 'swarm' of nerve cells communicating in a brain adds up to intelligence, and there is precedent to say that examining macro behaviour can throw light on the micro-opeations within. So blue sky research into crab swarms, even as seen through a journalist's funfair-distorting lens, is as good a way as any to gather insights into life's mysteries. What's important is good observation, good recording, and good peer publication. So, examining the behaviour of journalists and their subjects tells us what, exactly?

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.
