EPJ — Nonlinear Biomedical Physics is an open access journal, published under the brand SpringerOpen, dedicated to the application of nonlinear dynamics and integrative systems science to the quantitative modeling and understanding of how structure and function as well as dysfunctions and diseases emerge in complex biomedical matter and processes. Coverage is focused on the application-driven development of theoretical, experimental and computational techniques, including relevant methodologies, instrumentation and related advanced technology.

Researchers including George Church have made further progress on the path to fully rewriting the genome of living bacteria. Such a recoded organism, once available, could feature functionality not seen in nature. It could also make the bacteria cultivated in pharmaceutical and other industries immune to viruses, saving billions of dollars of losses due to viral contamination. Finally, the altered genetic information in such an organism wouldn’t be able to contaminate natural cells because of the code’s limitations outside the lab, researchers say, so its creation could stop laboratory engineered organisms from genetically contaminating wildlife. In the DNA of living organisms, the same amino acid can be encoded by multiple codons — DNA “words” of three nucleotide letters. Here, building on previous work that demonstrated it was possible to use the genetic equivalent of “search and replace” in Escherichia coli to substitute a single codon with an alternative, Nili Ostrov, Church and colleagues explored the feasibility of replacing multiple codons, genome-wide. The researchers attempted to reduce the number of codons in the E. coli code from 64 to 57 by exploring how to eradicate more than 60,000 instances of seven different codons. They systematically replaced all 62,214 instances of these seven codons with alternatives. In the recoded E.coli segments that the researchers assembled and tested, 63% of all instances of the seven codons were replaced, the researchers say, and most of the genes impacted by underlying amino acid changes were expressed normally. Though they did not achieve a fully operational 57-codon E. coli, “a functionally altered genome of this scale has not yet been explored,” the authors write. Their results provide critical insights into the next step in the genome rewriting arena — creating a fully recoded organism.

The blog take away: How is the key frequency of beta oxidation made in a mitochondria?Most people believe fat burning via beta oxidation is a fuel mediated mechanism but Dr. Doug Wallace’s data strongly suggests it is linked to the vibration state of the inner mitochondrial membrane. If so, how is the sun’s photoelectric abilities critical to this mechanism in mitochondria? Watch the video in the hyperlink closely from 50:00 – 59:00 for the clue.

Water surrounds each mitochondria in a cell with its MINOS layer. It is adjacent to the cytochrome 1 complex. Water has a high dielectric constant. It is 78 in bulk water, to be exact, Why is that critical? Well cytochrome one has a redox Fe-S couple that acts like a semiconductor for electrons. Electrons act differently in a semiconductor than they do when they are not captured by one. How much do you know about semiconductor integrated circuits? In a typical network in an integrated circuit, each network will include at least one driver, which must contain a source or drain diffusion and at least one receiver. This set up will consist of a gate electrode over a thin gate dielectric (look for a view of a MOS transistor on line if you’re unsure of this arrangement to get a visual.)

Luv this.


MIT biological engineers have devised a way to record complex histories in the DNA of human cells, allowing them to retrieve “memories” of past events, such as inflammation, by sequencing the DNA.

This analog memory storage system—the first that can record the duration and/or intensity of events in human cells—could also help scientists study how cells differentiate into various tissues during embryonic development, how cells experience environmental conditions, and how they undergo genetic changes that lead to disease.

“To enable a deeper understanding of biology, we engineered human cells that are able to report on their own history based on genetically encoded recorders,” says Timothy Lu, an associate professor of electrical engineering and computer science, and of biological engineering. This technology should offer insights into how gene regulation and other events within cells contribute to disease and development, he adds.

Ray believes we’re becoming gods.


People tend to ask Ray Kurzweil all manner of questions about technology and the future. But they also want to know about his own personal philosophy. In one session last summer, a questioner asked Kurzweil if he believes in God. Of course, many of us struggle with the question, he replied, and to him, it’s not unambiguous.

There’s variability in how we describe God, but he thinks there are some commonalities. Shared traits include creativity, love, and intelligence—attributes we tend to also value in conscious beings. To Kurzweil, consciousness is the ultimate measure of spirituality. Much of our morality is based on whether an entity is conscious or not (even though it’s still hard to define).

I consider myself a collector of sorts. I collect strange, bizarre notions and theories that warp traditional narratives about reality and existence. The following is a presentation of 10 of my favorite mind-blowing theories. There is compelling evidence for each, but you certainly don’t – and, for the sake of your sanity, probably shouldn’t – need to take them as gospel.

1. The Singularity: We will transcend biology and live as posthuman Gods.

This is why tech must never leave their eye off their companies, innovation, and future; unlike China many in big tech have become bogged down in US Politics, etc. instead of their own competitive landscape something that many industry leaders learned many decades ago. Granted, you must always be concern over regulations, etc.; however, some in tech went further than that by acting in some cases like they’re running for office meanwhile their competitors flourish and don’t bother themselves with background noise.

As the old saying goes “never mix politics and religion in the work place” and this is why. Now, both China and Russia are challenging US tech like never before because of tech’s own distractions outside their companies. And, yes some may say it is tied to the S. China Sea; however, that is just one of many excuses which is not the real reason behind the drop of Apple, Uber, etc. Frankly China is showing the world they are serious in their own commitment to dominate tech taking the title from the US. I suggest companies wake up and focus on what they do best which is tech not government politics. Want to be a politician then please resign and run for government office; and let others who are passionate about tech run tech.


The Chinese government has launched a $30bn venture capital fund aimed at upgrading technology in the country’s ailing industrial sector, a move reminiscent of Singapore’s state investment playbook. Led by big banks and government holding companies.
