OT: Optical communication enables 100 fold breakthough in super-computing,,,
Ultra-High-Speed Optical Communications Link Sets New Power Efficiency Record - Mar. 12, 2013 Excerpt: Ultrafast supercomputers that operate at speeds 100 times faster than current systems are now one step closer to reality. A team of IBM researchers working on a U.S. Defense Advanced Research Projects Agency (DARPA)-funded program have found a way to transmit massive amounts of data with unprecedentedly low power consumption.,,, Scientists predict that the supercomputers of the future -- so-called "exascale computers" -- will enable them to model the global climate, run molecular-level simulations of entire cells, design nanostructures, and more. "We envision machines reaching the exascale mark around 2020,,, By combining innovative circuits in IBM's 32-nanometer silicon-on-insulator complementary metal-oxide-semiconductor (SOI CMOS) technology with advanced vertical cavity surface emitting lasers (VCSELs) and photodetectors fabricated by Sumitomo Electric Device Innovations USA (formerly Emcore), Proesel and his colleagues created a power-efficient optical communication link operating at 25 gigabits per second using just 24 milliwatts of total wall-plug power, or 1 pJ/bit. ",, Proesel says. "We're continuing the push for lower power and higher speed in optical communications. There will always be demand to move more data with less energy, and that's what we're working toward." http://www.sciencedaily.com/releases/2013/03/130312134654.htm

An Electric Face: A Rendering Worth a Thousand Falsifications - September 2011 Excerpt: The video suggests that bioelectric signals presage the morphological development of the face. It also, in an instant, gives a peak at the phenomenal processes at work in biology. As the lead researcher said, “It’s a jaw dropper.” http://darwins-god.blogspot.com/2011/09/electric-face-rendering-worth-thousand.html The (Electric) Face of a Frog - video http://www.youtube.com/watch?v=ndFe5CaDTlI Not in the Genes: Embryonic Electric Fields - Jonathan Wells - December 2011 Excerpt: although the molecular components of individual sodium-potassium channels may be encoded in DNA sequences, the three-dimensional arrangement of those channels -- which determines the form of the endogenous electric field -- constitutes an independent source of information in the developing embryo. http://www.evolutionnews.org/2011/12/not_in_the_gene054071.html Optogenetic protein clustering and signaling activation in mammalian cells - January 2013 Excerpt: We report an optogenetic method based on Arabidopsis thaliana cryptochrome 2 for rapid and reversible protein oligomerization in response to blue light. We demonstrated its utility by photoactivating the ?-catenin pathway, achieving a transcriptional response higher than that obtained with the natural ligand Wnt3a. We also demonstrated the modularity of this approach by photoactivating RhoA with high spatiotemporal resolution, thereby suggesting a previously unknown mode of activation for this Rho GTPase. http://www.nature.com/nmeth/journal/vaop/ncurrent/full/nmeth.2360.html Using light to control cell (protein) clustering - February 12, 2013 Excerpt: Results of the study,, show how blue light can be used as a switch to prompt targeted proteins to accumulate into large clusters.,, "Our study shows a new use for using energy, in this case light, as a tool to understand and control cellular function. In this study, we demonstrated a new method for turning specific cell signaling pathways on and off with spatial and temporal precision, and use this to help better understand the dynamics of the pathway. At the same time, our technique can be used to control certain cell functions," Kane and Schaffer said.,,, http://phys.org/news/2013-02-cell-clustering.html
Finding light to play a regulatory role in turning specific cell signaling pathways on and off is no small thing to consider since cell signaling pathways are extremely complex with many different proteins involved in each specific pathway,,,

The mechanism and properties of bio-photon emission and absorption in protein molecules in living systems – May 2012 Excerpt: From the energy spectra, it was determined that the protein molecules could both radiate and absorb bio-photons with wavelengths of less than 3 micrometers and 5–7 micrometers, consistent with the energy level transitions of the excitons.,,, http://jap.aip.org/resource/1/japiau/v111/i9/p093519_s1?isAuthorized=no The Real Bioinformatics Revolution - Proteins and Nucleic Acids 'Singing' to One Another? Excerpt: the molecules send out specific frequencies of electromagnetic waves which not only enable them to ‘see' and ‘hear' each other, as both photon and phonon modes exist for electromagnetic waves, but also to influence each other at a distance and become ineluctably drawn to each other if vibrating out of phase (in a complementary way).,,, More than 1 000 proteins from over 30 functional groups have been analysed. Remarkably, the results showed that proteins with the same biological function share a single frequency peak while there is no significant peak in common for proteins with different functions; furthermore the characteristic peak frequency differs for different biological functions.,,, The same results were obtained when regulatory DNA sequences were analysed. http://www.i-sis.org.uk/TheRealBioinformaticsRevolution.php
Errors? What errors? Just another example of fine tuning. Mung
An amazing micro-machine with built-in quality control and error correction. And this is only a tiny part of a self-replicating system composed of millions of other such micro-machines of equal or greater complexity. It's almost like beating a dead horse to point out that it's Game Over for chance-plus-billions-and-billions-of-years. sagebrush gardener
