Biologist discusses a synthetic metabolic pathway that fixes carbon dioxide and synthetic biology

Posted by in categories: bioengineering, biological, climatology, sustainability

A synthetic metabolic pathway developed by Tobias Erb and his colleagues at the Max Planck Institute for Terrestrial Microbiology in Marburg converts CO2 from the atmosphere into organic matter more efficiently than plants are able to through photosynthesis. We asked the researcher what significance this process could have for climate protection, discussed the hurdles the research team had to overcome to achieve their goal, and looked at the new perspectives that synthetic biology opens up.

Does the synthetic metabolic pathway that fixes CO2 now represent an effective means of curbing climate change?

Firstly, we are aiming to understand the fundamental biological and chemical principles of how CO2 in gaseous form can be converted into organic molecules. Our primary motivation is not stopping . We are seeking to develop atmospheric CO2 as a source of carbon for the future using biological methods. Producing a CO2-neutral process or even one that removes CO2 from the atmosphere and has a positive impact on the climate would be a fantastic secondary effect.

Genetic engineering: Who cleans up the mess?

Posted by in categories: bioengineering, genetics, military

WASHINGTON – Scientists believe genetic engineering experiments have the potential to wipe out malaria and other illnesses that kill millions of people every year.

But they also acknowledge they could have unintended consequences that could be catastrophic.

So, over the next four years, the Pentagon’s Defense Advanced Research Projects Agency, dubbed DARPA, plans to develop a cleanup crew for engineered genes deemed harmful to the eco-system.

SynBio is gearing up

Posted by in categories: bioengineering, biotech/medical, economics, internet

We’re only starting in this space.


Synthetic Biology (SynBio) includes a large field of applications. Within this area biochemists combine engineering concepts and techniques with biology to design new genes that produce a specific protein. When this protein is an enzyme, bacteria and yeast in which such a gene is implanted can produce specific chemicals through a fermentation process. A large and growing number of businesses is active in this field. This became apparent once again at the EFIB-conference in Glasgow, last October. The workshop was chaired by John Cumbers, founder of the American SynBioBeta, an internet-site dedicated to sharing information and news on synthetic biology.

New Plant Synbio Tool Breaks With Tradition

Posted by in categories: bioengineering, biotech/medical, food

JBEI researchers develop efficient and affordable method for plant DNA assembly.

Researchers at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) in collaboration with Berkeley Lab’s Environmental Genomics & Systems Biology Division and the DOE Joint Genome Institute developed a versatile system (named jStack) which utilizes yeast homologous recombination to efficiently assemble DNA into plant transformation vectors. The new approach will impact plant engineering for the bioenergy, agricultural and pharmaceutical industries.

Although synthetic biology has provided solutions to many societal challenges, little research has been devoted to advancing synthetic biology in plants. Microbes, such as yeast and Escherichia coli (E. coli), have received much of the attention in developing synthetic biology tools due to their fast generation time and the ease of working with these organisms in laboratories. A shortage of characterized DNA parts, along with the difficulty of efficiently assembling multiple and large fragments of DNA into plant transformation vectors, has limited progress in studying and engineering plants to the same degree as their microbial counterparts.

IIT-B has come up with hydrogels mimicking natural brain tissue to cure Parkinson’s disease via stem cell therapy

Posted by in categories: bioengineering, biotech/medical, neuroscience

BENGALURU: After working for five years, a team of three from department of Biosciences and Bioengineering (BSBE) at Indian Institute of Technology (IIT), Bombay and IITB-Monash Research Academy has designed smart amyloid based hydrogels that are able to guide stem cell to differentiate to neuron and successfully transplanted these stem cells in the brain of Parkinson’s disease (PD) animal models with unique amyloid hydrogels.

Researchers Just Solved One of the Biggest Problems in Synthetic Biology

Posted by in categories: bioengineering, biological, genetics

In Brief

  • Researchers have discovered that placing synthetic genetic circuits in liposomes prevents them from interfering with one another, while still allowing them to communicate.
  • Not only could this new form of “modular” genetic circuits lead to more complex engineered circuits, it could also provide insight as to how the earliest life on Earth formed.

By applying engineering principles to biology, researchers can create biological systems that don’t exist naturally. A problem of synthetic biology, however, is that these engineered genetic circuits can interfere with each other. While beneficial on their own, some of these man-made circuits become useless when they come in contact with each other, and this bars them from being used to solve complex biological problems.

Turning back the aging clock

Posted by in categories: bioengineering, biotech/medical, genetics, life extension

SENS makes official comment on the excellent news about Mitochondrial repair from UCLA and Caltech.


So the big news is progress has been made on Mitochondrial repair. Our resident expert at the SENS Research Foundation, Dr. Matthew O’Connor of the MitoSENS project had this to say about the exciting news:

“New work from UCLA and Caltech has shown that a genetic pathway can be harnessed to selectively remove mutant mitochondria from the muscles of fruit flies. This work from Kandul et al is exciting because it raises the possibility of someday finding a way to control this genetic pathway in such a way to selectively delete mutant mitochondria. Further they did it in live flies in a tissue (muscle) where we are especially concerned about the impact of mitochondrial DNA mutations. Our ability to selectively control genetic pathways in non-genetically engineered animals (such as humans) is, however, extremely limited so it may be a long time before any clinical benefits can be realized from this research.” — Dr. Matthew O’Connor SRF

New era of ‘cut and paste’ humans close as man injected with genetically-edited blood

Posted by in categories: bioengineering, biotech/medical, genetics

A world where DNA can be rewritten to fix deadly diseases has moved a step closer after scientists announced they had genetically-edited the cells of a human for the first time using a groundbreaking technique.

A man in China was injected with modified immune cells which had been engineered to fight his lung cancer. Larger trials are scheduled to take place next year in the US and Beijing, which scientists say could open up a new era of genetic medicine.

The technique used is called Crispr, which works like tiny molecular scissors snipping away genetic code and replacing it with new instructions to build better cells.
