Will Microbes Replace Machines?

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

Just when we are getting accustomed to artificial intelligence in our daily lives, get ready for a new disruptor: synthetic biology, or syn-bio, the design and engineering of biological systems to create and improve processes and products. It promises to become a manufacturing paradigm of the future.

Recent advances in molecular, cell, and systems biology have enabled scientists to shift their focus from research of syn-bio to design and engineering, creating some truly mind blowing applications. By using microorganisms, for example, companies can now manufacture an infinite number of things, cell by cell, from scratch. This offers new ways of producing almost everything that humans consume, from flavors and fabrics to foods and fuels.

By the end of the decade, syn-bio may be used extensively in manufacturing industries that account for more than a third of global output, according to BCG Henderson Institute, Boston Consulting Group’s strategy think tank. Various sources estimate that the syn-bio market today is about $10 billion and is expected to reach $30 billion in the next five years.

First-of-its-kind instrument officially ushers in new era of X-ray science

Posted by in categories: bioengineering, biotech/medical, computing, health, science

Arizona State University has officially begun a new chapter in X-ray science with a newly commissioned, first-of-its-kind instrument that will help scientists see deeper into matter and living things. The device, called the compact X-ray light source (CXLS), marked a major milestone in its operations as ASU scientists generated its first X-rays on the night of Feb. 2.

“This marks the beginning of a new era of science with compact accelerator-based X‑ray sources,” said Robert Kaindl, who directs ASU’s Compact X-ray Free Electron Laser (CXFEL) Labs at the Biodesign Institute and is a professor in the Department of Physics. “The CXLS provides hard X-ray pulses with high flux, stability and ultrashort durations, in a very compact footprint. This way, matter can be resolved at its fundamental scales in space and time, enabling new discoveries across many fields — from next-generation materials for computing and information science, to renewable energy, biomolecular dynamics, drug discovery and human health.”

Building the compact X-ray light source is the first phase of a larger CXFEL project, which aims to build two instruments including a coherent X-ray laser. As the first-stage instrument, the ASU CXLS generates a high-flux beam of hard X‑rays, with wavelengths short enough to resolve the atomic structure of complex molecules. Moreover, its output is pulsed at extremely short durations of a few hundred femtoseconds — well below a millionth of one millionth of a second — and thus short enough to directly track the motions of atoms.

Engineering Cyborg Bacteria Through Intracellular Hydrogelation

Posted by in categories: bioengineering, biotech/medical, cyborgs, genetics, robotics/AI

Synthetic biology has made major strides towards the holy grail of fully programmable bio-micromachines capable of sensing and responding to defined stimuli regardless of their environmental context. A common type of bio-micromachines is created by genetically modifying living cells.[ 1 ] Living cells possess the unique advantage of being highly adaptable and versatile.[ 2 ] To date, living cells have been successfully repurposed for a wide variety of applications, including living therapeutics,[ 3 ] bioremediation,[ 4 ] and drug and gene delivery.[ 5, 6 ] However, the resulting synthetic living cells are challenging to control due to their continuous adaption and evolving cellular context. Application of these autonomously replicating organisms often requires tailored biocontainment strategies,[ 7-9 ] which can raise logistical hurdles and safety concerns.

In contrast, nonliving synthetic cells, notably artificial cells,[ 10, 11 ] can be created using synthetic materials, such as polymers or phospholipids. Meticulous engineering of materials enables defined partitioning of bioactive agents, and the resulting biomimetic systems possess advantages including predictable functions, tolerance to certain environmental stressors, and ease of engineering.[ 12, 13 ] Nonliving cell-mimetic systems have been employed to deliver anticancer drugs,[ 14 ] promote antitumor immune responses,[ 15 ] communicate with other cells,[ 16, 17 ] mimic immune cells,[ 18, 19 ] and perform photosynthesis.

A cnidarian parasite of salmon (Myxozoa: Henneguya) lacks a mitochondrial genome

Posted by in categories: bioengineering, biotech/medical

Year 2020 This type of parasite that feeds on salmon actually doesn’t need oxygen to live. Which means eventually there could be even gene editing that could essentially allow humans to not need as much air or could be independent of oxygen but only need anaerobic metabolisms perhaps. Really this can only expand our understanding of new ways to evolve humans to the next level.


Although aerobic respiration is a hallmark of eukaryotes, a few unicellular lineages, growing in hypoxic environments, have secondarily lost this ability. In the absence of oxygen, the mitochondria of these organisms have lost all or parts of their genomes and evolved into mitochondria-related organelles (MROs). There has been debate regarding the presence of MROs in animals. Using deep sequencing approaches, we discovered that a member of the Cnidaria, the myxozoan Henneguya salminicola, has no mitochondrial genome, and thus has lost the ability to perform aerobic cellular respiration. This indicates that these core eukaryotic features are not ubiquitous among animals. Our analyses suggest that H. salminicola lost not only its mitochondrial genome but also nearly all nuclear genes involved in transcription and replication of the mitochondrial genome. In contrast, we identified many genes that encode proteins involved in other mitochondrial pathways and determined that genes involved in aerobic respiration or mitochondrial DNA replication were either absent or present only as pseudogenes. As a control, we used the same sequencing and annotation methods to show that a closely related myxozoan, Myxobolus squamalis, has a mitochondrial genome. The molecular results are supported by fluorescence micrographs, which show the presence of mitochondrial DNA in M. squamalis, but not in H. salminicola. Our discovery confirms that adaptation to an anaerobic environment is not unique to single-celled eukaryotes, but has also evolved in a multicellular, parasitic animal. Hence, H. salminicola provides an opportunity for understanding the evolutionary transition from an aerobic to an exclusive anaerobic metabolism.

Genetic engineering sheds light on ancient evolutionary questions

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

Cyanobacteria are single-celled organisms that derive energy from light, using photosynthesis to convert atmospheric carbon dioxide (CO2) and liquid water (H2O) into breathable oxygen and the carbon-based molecules like proteins that make up their cells. Cyanobacteria were the first organisms to perform photosynthesis in the history of Earth, and were responsible for flooding the early Earth with oxygen, thus significantly influencing how life evolved.

Geological measurements suggest that the atmosphere of the early Earth—over three billion years ago—was likely rich in CO2, far higher than current levels caused by , meaning that ancient had plenty to “eat.”

But over Earth’s multi-billion-year history, atmospheric CO2 concentrations have decreased, and so to survive, these bacteria needed to evolve new strategies to extract CO2. Modern cyanobacteria thus look quite different from their ancient ancestors, and possess a complex, fragile set of structures called a CO2-concentrating mechanism (CCM) to compensate for lower concentrations of CO2.
