Fuel From Waste? – ScienceNOW

“A team led by Jay Keasling, a bioengineer at the Joint BioEnergy Institute in Emeryville, California, worked to extend the strategy to make more commonly used fuels. They used Escherichia coli, a bacterium into which it’s relatively easy to insert new genes. They started by creating two strains of E. coli, inserting genes for breaking […]

Suicide-Bombing Bacteria Could Fight Infections – ScienceNOW

“The researchers tweaked the genes that allow P. aeruginosa to detect other members of its species and put this synthetic genetic code into E. coli’s genome. They also gave E. coli a gene for making a modified pyocin that is toxic to P. aeruginosa. By linking the pyocin gene to the sensing genes, the researchers […]

Follow our efforts to get bio panels into SXSW 2012

Folks, @thisischristina (and writer at SciAm’s Oscillator) and I both submitted panel proposals for SXSW 2012. We’re going to need some help getting into the program. Voting is from 15aug to 02sep with program announcements starting end of October. [see Panel Picker pages] Save this link [http://www.molecularist.com/tag/sxsw2012] to keep up with info about this process […]

Ginkgo organism engineers and the pipe – Ginkgoo blog

“Here I’ll try to give a high-level picture of Ginkgo’s pipeline for organism engineering. If you’ve checked out our webpage, you’ll see that we have several different organism engineering projects happening at Ginkgo that span several different hosts. Our goal was to build out a pipeline that could support the engineering of all these very […]

Chemically evolved bacteria

“European scientists have created an Escherichia coli strain with a separate genome using chlorinated DNA. The genome should be unable to transfer back into unmodified bacteria, leading to what the researchers call a ‘genetic firewall’.” First arsenic, now chlorine. In my grad school days, we were studying DNA-protein interactions by modifying specific atoms on the […]
