Synthetic biology has been described as a kind of “genetic engineering on steroids”.


Synthetic biology …Simply mentioning this term — whether at a cocktail party or on a pop culture TV show — evokes a plethora of responses. These could range from puzzled looks to questions about the somewhat famous, though likely quixotic, quest to resurrect a woolly mammoth from remnants recovered in Siberia. Also, on the radar screen is synthetic biology as applied to the development of drugs and biological weapons. But flying below the radar — and, oddly, the sweet spot for investments by governments and private industry — is a less sexy focus on the industrial uses of synthetic biology. Such uses range from environmental clean-ups to new energy sources.

What do we mean by “synthetic biology”? To keep things simple, synthetic biology has been described as a kind of “genetic engineering on steroids”. Plain, old genetic engineering includes a range of strategies, the classic one being transgenics — copying a gene from one biological species and inserting it into the cell nucleus of another species. This has enabled bacteria to produce human insulin and plants to produce their own defenses against pests and herbicides such as glyphosate. Genetic engineering also include CRISPR technology, which can function as a kind of line item editing.

In contrast, synthetic biology involves the rewriting of large segments of the genomes of organisms, resulting in what effectively are new organisms. Whereas the mammoth revival is synthetic biology and while it gets good media attention, it’s more a cartoon use of synthetic biology. On the other hand, the transformations that could occur by creating new life forms — that’s really what synthetic biology is — may not be so sexy. Yet, they could change the world.

Now, scientists at Washington University in St. Louis have developed a way to use gene editing system CRISPR-Cas9 to edit a mutation in human-induced pluripotent stem cells (iPSCs) and then turn them into beta cells. When transplanted into mice, the cells reversed preexisting diabetes in a lasting way, according to results published in the journal Science Translational Medicine.

While the researchers used cells from patients with Wolfram syndrome—a rare childhood diabetes caused by mutations in the WFS1 gene—they argue that the combination of a gene therapy with stem cells could potentially treat other forms of diabetes as well.

Engineering researchers developed a next-generation miniature lab device that uses magnetic nano-beads to isolate minute bacterial particles that cause diseases. Using this new technology improves how clinicians isolate drug-resistant strains of bacterial infections and difficult-to-detect micro-particles such as those making up Ebola and coronaviruses.

Ke Du and Blanca Lapizco-Encinas, both faculty-researchers in Rochester Institute of Technology’s Kate Gleason College of Engineering, worked with an international team to collaborate on the design of the new system — a microfluidic device, essentially a lab-on-a-chip.

Drug-resistant bacterial infections are causing hundreds of thousands of deaths around the world every year, and this number is continuously increasing. Based on a report from the United Nations, the deaths caused by antibiotics resistance could reach to 10 million annually by 2050, Du explained.

China is well on its way to producing an effective vaccine against SARS-CoV-2, the coronavirus that causes COVID-19. It will surely be made available to the world at minimal or no cost.

How will the US and the world respond to that eventuality? Will the American people accept a vaccine made by evil Communist China? Will they condemn it as a diabolical plot by the “red menace/yellow peril” to turn Americans into zombies?

Most likely.


The first Covid-19 new coronavirus vaccines developed in China have entered the clinical stage. A few days ago, researchers released detailed data on the inactivated vaccine, and the result showed that it can neutralize 10 new coronaviruses.

The best way to deal with the Covid-19 new coronavirus epidemic is vaccines. Currently, countries are accelerating vaccine research and development.

Two kinds of vaccines in China have entered the clinical stage. Among them, the innovative recombinant vaccine product led by the academician Chen Wei, a member of the Chinese Academy of Engineering and the researcher of the Academy of Military Medical Sciences, led by the team of researchers, officially entered the second phase of the recombinant coronavirus (adenovirus vector) vaccine Clinical Trials.

Shahrad Daraeikia, Jack Wang, and Dr. Jean-Philippe Buerckert sit down together with Harry Glorikian at MoneyBall Medicine to talk about our ultra rapid antibody discovery race to a cure for COVID19.

Two new studies by researchers in Tel Aviv University and Harvard University on the subject were published in the journal Nature Biomedical Engineering on Monday.

Organs-on-a-chip were first developed in 2010 at Harvard University. Then, scientists took cells from a specific human organ — heart, brain, kidney and lung — and used tissue engineering techniques to put them in a plastic cartridge, or the so called chip. Despite the use of the term chip, which often refers to microchips, no computer parts are involved here.

UC San Francisco researchers have discovered how a mutation in a gene regulator called the TERT promoter—the third most common mutation among all human cancers and the most common mutation in the deadly brain cancer glioblastoma—confers “immortality” on tumor cells, enabling the unchecked cell division that powers their aggressive growth.

The research, published September 10, 2018 in Cancer Cell, found that patient-derived glioblastoma cells with TERT promoter mutations depend on a particular form of a protein called GABP for their survival. GABP is critical to the workings of most cells, but the researchers discovered that the specific component of this protein that activates mutated TERT promoters, a subunit called GABP-ß1L, appears to be dispensable in : Eliminating this subunit using CRISPR-based gene editing dramatically slowed the growth of the human in lab dishes and when they were transplanted into mice, but removing GABP-ß1L from healthy cells had no discernable effect.

“These findings suggest that the ß1L subunit is a promising new drug target for aggressive glioblastoma and potentially the many other cancers with TERT promoter mutations,” said study senior author Joseph Costello, Ph.D., a leading UCSF neuro-oncology researcher.

Networks are at the heart of everything from communications systems to pandemics. Now researchers have found that a unique type of network also underlies the structures of critical cellular compartments known as membraneless organelles. These findings may provide key insights into the role of these structures in both disease and cellular operations.

“Prior to this study, we knew the basic physical principle by which these protein-rich compartments form — they condense from the cytoplasm into liquid droplets like dew on a blade of grass,” said David Sanders, a post-doctoral researcher in Chemical and Biological Engineering at Princeton University. “But unlike dew drops, which are composed of a single component (water), cellular droplets are intimidatingly complex. Our work uncovers surprisingly simple principles that we think are universal to the assembly of liquid organelles, and opens new frontiers into studying their role in health and disease.”

Sanders is the lead author in an article in the journal Cell describing a blueprint for the assembly of these liquid structures, also called condensates. The researchers looked closely at two types of condensates, stress granules and processing bodies (“P-bodies”). In the Cell paper, researchers directed by Clifford Brangwynne, a professor of Chemical and Biological Engineering at Princeton and the Howard Hughes Medical Institute, combined genetic engineering and live cell microscopy approaches to reveal the rules underlying the assembly and structure of stress granules, and why they remain distinct from their close relatives, P-bodies.

A desirable option would be to use CRISPR gene editing to essentially cut out the unwanted gene. There are, however, many challenges ahead.


If you want to remove an undesirable gene from a population, you have a couple theoretical options — one that most people might find unthinkable, and one that lies outside our current scientific abilities.

The first involves locating a group of people without a particular gene and designing breeding programs around them. It would mean mating people in ways that society would consider incestuous. And we’ve seen the difficulties that result from that in the past — marriages between close relatives were a notorious cause of hemophilia in European royal families, for example.

A much more desirable option would be to use CRISPR gene editing to essentially cut out the unwanted gene. There are, however, many challenges ahead for such a strategy. Chief among them is the need to find mutations that, by themselves, are linked to particular diseases or disorders. And then we need guarantees that CRISPR will edit the correct genes.
