Algae to Oil

Very recently scientists in the United States figured out how to turn algae into crude oil in less than an hour.  Supported by the U.S. Department of Energy’s National Alliance for Advanced Biofuels and Bio-products, This is an incredible discovery in the biofuel world. In nature, it takes millions of years for this process to…

Microbial Assassins

The human body is a pathogen killing machine. We have an incredibly developed immune system containing a variety of cells capable of binding and “killing” foreign bacterial cells. Our bodies are in constant contact with bacteria in the air, water, and soil. In fact, the human body contains roughly 10x more bacterial cells than human…

Quenching the Water Crisis

Nearly a billion people around the world do not have access to clean and safe water with the majority of those people residing in developing countries. The water crisis in third world countries is severe – more than 3.4 million people die each year from water, sanitation, and hygiene-related causes. Nearly all of those deaths, 99 percent, occur…

Synthetic Glycolysis

One division of synthetic biology combines natural parts to create something unique, like our glowing plant project which combines the glowing protein from a firefly with a traditional plant. This seems to be an obvious first step in synthetic biology, because nature has already produced so many incredible proteins and biological mechanisms. By separating nature…

CRISPR and the Art of Genome Editing

One of the most impressive developments in molecular biology is the
ability to change the DNA of living organisms.  Techniques for real-time
genetic modification are complex and diverse; often involving a large
protein capable of binding to a specific sequence of DNA and cutting it at
that sequence.  Zinc finger nucleases (ZLN’s) and transcription
activator-like effector nucleases (TALEN’s) are examples of such protein
complexes.  However, these techniques remain time consuming and
costly for the examination and alteration of large genomes.
And while the genomes of prokaryotic organisms like bacteria are
relatively simple, those of eukaryotic organisms like plants and mammals
are quite complicated and difficult to modify.  Fortunately, researchers in
Harvard professor George Church’s laboratory are developing a
technique called CRISPR (clustered regularly interspaced short
palindromic repeats) for altering the DNA of human cells. CRISPR, like
most techniques in molecular biology, is derived from a natural process
in bacteria and archaea as an immune response to invading viruses.
In CRISPR, a small 20 nucleotide strand of RNA (sgRNA) binds to a
DNA region of interest.  This sgRNA is bound to a protein (Cas9) which
breaks the DNA strand, allowing for an additional DNA segment to be
inserted between the break.  CRISPR has also been used as a means to
regulate the activity of DNA which is already present in an organism’s
genome, either by increasing or decreasing protein expression.
The biological impact of scientists and doctors developing a means for
editing human DNA is enormous.  An individual with a disease could
have their genome sequenced to determine their genetic defect;
scientists could create a complement RNA molecule to bind to this
mutated DNA region, cut, and replace it with a fully functioning DNA
Synthetic biologists could also use this technique to add completely
unique gene segments to human beings. From a moral standpoint,
improvement of the human being can be a controversial topic – critics
claim that we do not have the right to ‘play God’, but I think we would all
agree; if CRISPR can give me wings or the ability to produce my own
milk, I will forget about any ethical dilemma.

Beans and Biotechnology

We have all heard of the negative health consequences that come with consuming trans-fats from foods. Trans fats are especially bad for your heart, as they cause arteries to clog, raise your “bad” (LDL) cholesterol and lower your “good” (HDL) cholesterol. Trans fat, also known as trans-fatty acids, are actually considered to be the worst…

Have Your Cake and Tomatoes Too

We constantly watch what we eat, conscious of lowering our ‘bad’ cholesterol (LDL) and raising our ‘good’ cholesterol (HDL). We may not always understand the biology and science behind cholesterol production, but we avoid high-fat foods to prevent the clogging of our arteries, just as science and doctors have always advised. Until now, scientists believed…

Theoretical Medical Biology

Synthetic biology is an incredibly wide-reaching field with enormous possibilities.  And while I’m impressed with news articles reporting synthetic algae which produce biofuels and synthetic semiconductors; I’m left wondering how synthetic biology will improve human health.  This is a difficult question, both biologically and morally.  Is it morally acceptable to change our genes to improve…

The RNA Folding Phenomenon

  Synthetic biology offers a variety of techniques for changing living beings for the benefit of mankind.  By changing the DNA sequence of a cell, it will produce novel proteins with unique functions.  However, there are limitations to the proteins which can be produced. One commonly recognized problem is that changes to the amino acid…
