In Greek mythology, the Chimera is a monster that is part lion, part goat and part snake. Far from reality, sure, but the idea of mixing and matching creatures is real — and has ethicists concerned.

That’s because last week, the National Institutes of Health proposed a new policy to allow funding for scientists who are creating chimeras — the non-mythological kind. In genetics, chimeras are organisms formed when human stem cells are combined with tissues of other animals, with the potential for creating human-animal hybrids.

Russian scientists said they have artificially produced a unique molecule that can rapidly regenerate damaged human tissue, boasting both antibacterial and antiviral defenses, as well as stem cell growth stimulation.

The peptide, Acegram, was developed at a laboratory in the Russian Ural city of Chelyabinsk.

The US Department of Defense has developed a portable, on-demand biopharmaceutical production system that could be used in warzones to make treatments at point-of-care.

The platform was developed as part of a US Defense Advanced Research Projects Agency (DARPA) program to provide far-forward-deployed Service members “what they need when they need it, obviating the need for individual drug stockpiling, cold storage, and complex logistics,” Tyler McQuade, program manager for DARPA’s Battlefield Medicine program, told Biopharma-Reporter.com.

The platform, developed in conjunction with researchers at the Massachusetts Institute of Technology (MIT), consists of a biologics expression system engineered to secrete multiple therapeutic proteins and a millilitre-scale perfusion microfluidic platform.

Synthetic biology is an emerging and rapidly evolving engineering discipline. Within the NCCR Molecular Systems Engineering, Scientists from Bernese have developed a version of the light-driven proton pump proteorhodopsin, which is chemically switchable and it is also an essential tool to efficiently power synthetic cells and molecular factories.

Synthetic biology is a highly complex field with numerous knowledge branches that incorporate physics, biology, and chemistry into engineering. It aims to design synthetic cells and molecular factories with innovative functions or properties that can be applied in medical and biological research or healthcare, industry research.

These artificial systems are available in the nanometer scale and are developed by assembling and combining current, synthetic or engineered building blocks (e.g., proteins). Molecular systems are applicable for a wide range of applications, for instance these systems can be used for waste disposal, medical treatment or diagnosis, energy supply and chemical compound synthesis.

Hmmm.

With the advent of CRISPR genetic engineering technology, humanity is on the cusp of an evolutionary revolution. We now possess the technology to modify our own genetic code (DNA). In a few more years, it will become more reliable, less expensive, and more available.

While existing methods like cold, flash and cloud storage are trying to remake themselves in the age of Big Data, there are also a number of alternative methods being developed that suggest looking outside of traditional methods could be our best bet for storing and managing such unprecedented amounts of data.

Here are three methods to look out for:

We are about to witness a data storage breakthrough in which digital information could be embedded into the primary fabric of our being: the double helix of DNA. As a storage system, DNA is both compact and durable, with a single gram of DNA able to store almost a zettabyte of digital data. Now that scientists can successfully create synthetic DNA, it follows that we will be able to control what information gets stored on those strands.

In a set of studies in mice bearing human tumors, nanoparticles designed to bind to a protein called P-selectin successfully delivered both chemotherapy drugs and targeted therapies to tumor blood vessels. Targeting the blood vessels improved the delivery of drugs to tumor tissue, causing the tumors to shrink and improving how long the mice lived.

A tumor’s blood vessels can serve as a barrier to engineered drug-delivery systems like nanoparticles, which may not be able to cross the blood vessel wall. However, the same blood vessels may express proteins—such as P-selectin—that researchers can potentially exploit, by engineering their nanoparticles to recognize and latch onto those proteins, which enables them to reach the tumor.

With only 9 days left on the SENS cancer fundraiser here is an article from Fightaging! that explains why finding novel solutions to treating cancer is critical in the roadmap to longer healthier lives.

This year’s SENS rejuvenation research crowdfunding event puts the spotlight on the SENS Research Foundation’s cancer program. So far more than 300 people have donated, and more than $26,000 has been raised; with ten days left to go, it won’t take that much more of an effort to reach the same number of donors and the same level of support given to last year’s fundraiser, and which led to the success in that research program. As for all of the SENS research initiatives in the science of aging, the SENS Research Foundation’s work on cancer aims to support a big, bold goal in medicine: to build a single type of therapy that can be used to effectively treat all forms of cancer. When achieved, that will greatly increase the pace of progress towards control of cancer, the goal of finally ending cancer as a threat to health. At present the cancer research community spends much of its time and funding on approaches that are highly specific to only one or only a few of the hundred of subtypes of cancer. That is no way to win any time soon, as even with the vast funding devoted to cancer research, there are just too many forms of cancer and too few researchers. What is needed is to change the strategy, to focus on approaches to the treatment of cancer that are no more expensive to develop, but that far more patients can benefit from.

The most promising approach to a universal cancer therapy is to block telomere lengthening in cancerous tissues. Telomeres are a part of the mechanism that limits cell division in all human cells other than stem cells, repeating DNA sequences at the ends of chromosomes that shorten every time a cell divides. In order to achieve unfettered growth all cancers must bypass this limit by continually lengthening their telomeres, a goal that is achieved through mutations that allow cancer cells to use telomerase or the alternative lengthening of telomeres (ALT) processes. If both telomerase and ALT can be blocked in cancer tissue, then the cancer will wither; this is such a fundamental piece of cellular machinery that there is no expectation that cancer cells could find a way around it. Block only one of these two methods of telomere lengthening, however, and the cancer will probably switch to use the other. This has been observed in mice.

Crispr is a biotechnology that’s making genetic editing easier, cheaper, and far more accessible, but it has also been called a major security threat. Do such advances in biotechnology make the bioweapons convention obsolete?
