Still Cautious Around Synthetic Biology

Wednesday, September 15, 2010 0 comments
A recent news article in Medical News Today talks about a survey of 1000 U.S. adults and their opinions of synthetic biology. The survey was conducted by Hart Research Associates and the Synthetic Biology Project at the Woodrow Wilson Center.

Two thirds of those surveyed believe that synthetic biology should be a field that moves forward, while the remaining third believe we should put a ban on research until the implications and risks are fully assessed.

"The survey shows that attitudes about synthetic biology are not clear-cut and that its application is an important factor in shaping public attitudes towards it," said Geoff Garin, President of Hart Research.

Altruism in bacteria

Wednesday, September 1, 2010 0 comments
Dr. Collins from Harvard found that bacteria tend to show altruistic behaviours. Some bacteria can give up their own survival for the better survival of the group, which is termed altruism. This kind of behaviour was only found in mammals but now is found in bacteria. Research shows that a bacterium with antibiotic resistance can
"donate" its plasmid to the other bacteria to create an antibiotic resistant population.
This has medical implications says Dr. Collins. It could mean that, "We'll know that even an isolate that shows no resistance can put up a stronger battle against antibiotics thanks to its buddies." For more information click here.
Synthetic biology could be used to study this altruistic behaviour further and explore its implication more so.

Synthetic Biology: The Card Game

0 comments
The ESRC Genomics Forum has developed a version of the dialogue game Democs. In this game, participants will learn about, dicuss, and give thier views on issues in synthetic biology. An example of one card is: "We think it’s OK for humans to make all kinds of inanimate machines. But should we also design and make new living organisms that can reproduce themselves?". If your interested in playing the game, instructions and cards are available on www.genomicsnetwork.ac.uk.

Biofilms for the Future

Friday, August 27, 2010 0 comments
Synthetic biology isn't always a "Frankenstein-sounding" field of science, like one Los Angeles Times article puts it. While some labs like the Venter lab have synthesized and inserted a complete bacterial genome, most other labs, including those from iGEM, have much more modest and practical goals.

For example, the Groningen team is designing a way to use bacteria to create self-assembling film that repels water. By integrating a gene that produces hydrophobic proteins into bacteria, a new strain can be developed that can produce rigid biofilm. The process can be stopped with exposure to UV light.

This project can potentially be cheaper and less toxic than the expensive chemicals used to waterproof materials currently. Repelling water is an effective way to reduce bacterial and fungal growth on surfaces, as well as resisting corrosion because it keeps the surface clean and dry. Imagine: maybe in the future we can rustproof our car parts by letting bacteria do all the work for us.

Now isn't that neat?

Synthetic Immune System?

Wednesday, August 25, 2010 0 comments
Imagine taking a drop of your blood, dripping it into a bowl and having it travel through a network of vessels to different colonies of yeast. Each colony would act as an external biosensor for your body detecting a variety of deficiencies and possible anomalies that could be present. It is personalized medicine to the extreme, customized to your body and lifestyle. For example, if you had anaemia the yeast would monitor your iron levels in your blood and alert you if they got low. A different colony of yeast could even synthesize the needed iron for you, which would be sent back to you through the network of vessels, to be absorbed through a mouthpiece. Sound fictitious? Well that’s probably because it is. But Tuur van Balen, a designer in London has just this vision. He calls it the Synthetic Immune System. He imagines that in the future, synthetic biology could lead to a more personalized approach to medicine where we might even outsource our own metabolic actions to engineered organisms such as Yeast. He displayed his model and vision at an exhibition at the Royal College of Art in March. For more information, check out this link to his website.

"Playing God", a meaningless phrase?

Thursday, August 5, 2010 0 comments
The recent accomplishments of the Venter lab have caused a lot of controversies in the public eye, one of which is the perspective that humans should not be "playing god" with research pertaining to synthetic life. The Ethical Perspective News at the University of Oxford has an interesting article with a very different viewpoint.

Synthetic Biology Awareness

Wednesday, July 28, 2010 0 comments
May 27, 2010. Upon Craig Venter's recent announcement that he has successfully inserted the synthetic genome of genitalia mycoplasma into an empty cell, the media has developed huge interest in the matter. This coincided with President Barack Obama's decision earlier to order a six month review of synthetic biology. The panel that is reviewing Obama's request include Venter and several of his synthetic biology colleagues including Jay Keasling and Drew Endy. House committee members lack knowledge regarding synthetic biology. However they were interested in the potential of synthetic biology such as in the areas of synthetic fuels or synthetic compounds. This article also mentions the selling point of this meeting as the commercialization of synthetic biology based on the vested interest of the panel.

Synthetic Biology Matters to the President!

Tuesday, July 27, 2010 0 comments
On July 8-9, 2010 Drew Endy and several of his colleagues were invited to the White House to discuss the ethical considerations of synthetic biology. This meeting was more for updating the Obama administration to the development and advances in the field of synthetic biology. The meeting is in response to Craig Venter's current insertion of synthetic genitalia mycoplasma genome. There are videos documenting their discussion here, and an official letter written by Barack Obama to Dr. Amy Gutmann inquiring about the potential effects of synthetically created genome.

Barack Obama's letter about synthetic biology can be found here. (PDF)

This will be covered in more detail soon!
