The length of non-stop nsDNA is about 5 to 10 times longer in communal bacteria than pathogens. Half the nsDNA is paired. Have I missed a reference?

I have an observation and a correlation that is strong enough to present in a preliminary and semi-quantitative form before the full study ends. If one calculates the distance in nucleotides...

To what extent is RAM shared in large parallel computers?

It would be nice to hear answers that talk about physical limitations as well as answers that discuss how efficiently low-level software anticipates memory allocation.

Is there a restriction in PvNP to 0's, 1's, and NAND?

If I am not mistaken, anything we can compute in a Turing Machine is reducible to 1's, 0's, and only one logical operation: NAND. I can't see how cycles can be counted any other way. Is that a...

Would you consider the synthesis of proteins with no apparent function to be storage of Prigogine negentropy?

Such proteins have various oxidation states of Nitrogen and Carbon within prefabricated amino acids - a survival advantage for times when negentropy, favorable redox potentials, and energy are not...

Is it correct to identify t and t' from the Twin Paradox with (for example) computational scaling factors of N! and N^2 by travelling at high speed?

t’ = t (( 1 – (v^2 / c^2 ))^-0.5) Thus a brute force calculation of the Travelling Salesman Problem (TSP), scaling as N! cities, looks like an N^2 scaling to a Traveler at high velocity. As...
