While the recent cases of Ebola and Zika contributed to an emphasis on research, response, and policy related to EIDs, the meeting also had presentations on emerging biotechnologies. Of particular note was the Synthetic Biology panel, which focused on the current state of synthetic biology, its use in the health security defense enterprise, and the policy conundrums that need to be addressed.

Synthetic Biology – Complexity through Simplification

The first presenter, Dr. Christopher Voigt of the Synthetic Biology Center at MIT, noted that synthetic biology was the application of engineering principles to biological systems. The end goal of this bioengineering framework is to leverage ever-increasing computer capabilities to simplify both the designing and writing of genomic sequences. Further simplification would then allow for the creation of more complex systems.

Cancer care delivery has been mostly unchanged for the past 50 years but now needs a new model, a centaur, say Stanford University academics.

Wish he & a couple of others would join this ranks that others are on which makes way more sense plus benefits the masses tremendously. Musk needs to join others in their work to enhance humans via Quantum Biosystems as this work is already showing signs of success across multiple areas such as anti-aging, disease elimination, intelligence & communications, security, reduction in costs of healthcare & social programs, advancements in new creative innovations in technology & medicine, new industry new growth/ economic expansion, elimination of starvation, etc.

How can humans stay relevant in an age of artificial intelligence? Elon Musk thinks cyborgs are the answer.

The Tesla and SpaceX CEO discussed the need for a “merger of biological intelligence and digital intelligence” during a talk on Monday at the World Government Summit in Dubai, CNBC reported.

New work has demonstrated that bone injuries can be repaired using a sheet of a carbon compound that has photocatalytic characteristics, and combining it with stem cells derived from human bone marrow. These developments could lead to new treatments that can exert a powerful positive effect on skeletal fractures or periodontal disease. Check out the short video below that summarizes the findings in the report, which was published in the journal ACS Nano.

The scientists found that a chemical sheet made of carbon nitride, which absorbs red light, can support the growth of bone cells — osteogenic differentiation — because of the activation of a molecule that promotes gene expression. That molecule is a transcription factor called runt-related transcription factor 2 or Runx2. The absorption of red light and the emission of fluorescence by the carbon nitride sheets accelerates bone regeneration. It seems that when the sheets are exposed to red light in liquid conditions where cells are growing, electrons are released, which stimulates the accumulation of calcium in cell cytoplasm.

CRISPR/Cas9, a powerful gene editing technique that has already been used in a human, is thought by many as a “cut and paste” for DNA in living organisms. While in a sense that is what happens, delivering the ribonucleoprotein that does the genetic editing and the RNA that hones in on the target, into the cellular nucleus without being damaged is a challenge. That is why the efficiency of successful edits remains very low. Researchers at University of Massachusetts Amherst have now come up with nanoparticles that protect the protein and RNA as they’re brought to their work site.

The nanoparticles are engineered around their cargo and have shown a 90% success rate of getting the cargo into the nucleus, and a 30% editing efficiency, which is “remarkable” according to the researchers. So far the team has tested their technique on cultured cells, but they’re already working on trying the same in laboratory animals. As part of their research, they developed a novel way of tracking the Cas9 protein inside the cells, something that will certainly help other scientists in this area.

“By finely tuning the interactions between engineered Cas9En protein and nanoparticles, we were able to construct these delivery vectors. The vectors carrying the Cas9 protein and sgRNA come into contact with the cell membrane, fuse, and release the Cas9:sgRNA directly into the cell cytoplasm,” in a statement said Vincent Rotello, lead author of the study in ACS Nano. “Cas9 protein also has a nuclear guiding sequence that ushers the complex into the destination nucleus. The key is to tweak the Cas9 protein,” he adds. “We have delivered this Cas9 protein and sgRNA pair into the cell nucleus without getting it trapped on its way. We have watched the delivery process live in real time using sophisticated microscopy.”

Quantum mechanics, the physics that governs nature at the atomic and subatomic scale, contains a host of new physical phenomena to explore quantum states at the nanoscale. Though tricky, there are ways to exploit these inherently fragile and sensitive systems for quantum sensing. One nascent technology in particular makes use of point defects, or single-atom misplacements, in nanoscale materials, such as diamond nanoparticles, to measure electromagnetic fields, temperature, pressure, frequency and other variables with unprecedented precision and accuracy.

Quantum sensing could revolutionize medical diagnostics, enable new drug development, improve the design of electronic devices and more.

For use in quantum sensing, the bulk nanodiamond crystal surrounding the point defect must be highly perfect. Any deviation from perfection, such as additional missing atoms, strain in the crystalline lattice of the diamond, or the presence of other impurities, will adversely affect the quantum behavior of the material. Highly perfect nanodiamonds are also quite expensive and difficult to make.

This article does try to highlight what and where we are going with the merge of bio and technology. However, what has been shown to date is all very invasive as Quantum Biology has remained a gap in this development work until recently. Thanks to DARPA and others in the private sector who are working on technologies that leverages Quantum Biology principles to develop new integrated Biosystem technologies; we will see amazing work in cell circuitry and connectivity in areas of bio-security, BMI, prosthetics, immunology, anti-disease, reverse aging, etc.

These might sound like outlandish predictions, but DARPA’s Sanchez said it’s not as crazy as it might have sounded several years ago.

“Advancement of A.I. is making machines more powerful in the way they can understand everything from scientific papers to interpreting them and helping us solve big problems,” said Sanchez. “Another aspect to consider is our society [is] embracing things like wearables that… allow algorithms to analyze our physiology. Great examples of that are being able to monitor your sleep patterns and provide feedback on if you should change the time you go to bed or wake up in the morning.”

CHICAGO (Reuters) — Powerful gene editing tools may one day be used on human embryos, eggs and sperm to remove genes that cause inherited diseases, according to a report by U.S. scientists and ethicists released on Tuesday.

The report from the National Academy of Sciences (NAS) and the National Academy of Medicine said scientific advances make gene editing in human reproductive cells “a realistic possibility that deserves serious consideration.”

H.G. Wells was a writer of fantastic science fiction during the 1890s. He is considered one of the fathers of science fiction and wrote novels whose stories remain popular today. He wrote about time travel in “The Time Machine”, about interplanetary conflict originally made popular by the Orson Wells’ “The War of the Worlds” and in “The Island of Dr. Moreau” he described beings that were part human and part animal. Two of the three remain pure science fiction but one is on the verge of becoming a reality. Do you know which one?

In August, 2016, the National Institutes of Health announced that it was lifting its ban on research that introduces stem cells from humans into animal embryos. Stem cells have the ability to evolve into any human cell and can grow into any human tissue. The goal of this type of research is to grow human tissues and eventually human replacement organs in animals. What an innovative way to improve upon transplantation medicine! But to realize this potential, we would create an organism that is part animal and part human! These hybrids are the stuff of ancient mythology. These mixtures of different animals are called chimeras after the mythical ancient Greek creature that was part lion, snake and goat. One goal of today’s research is to produce tissues and organs for experimentation that will improve our understanding of human disease. An alternative and longer term goal would be to produce organs directly for human transplantation.
