The first dynamic regulatory system that prevents the build-up of toxic metabolites in engineered microbes has been reported by a team of researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI). The JBEI researchers used their system to double the production in Escherichia coli (E. coli) of amorphadiene, a precursor to the premier antimalarial drug artemisinin. Using genome-wide transcriptional analysis, the JBEI researchers identified native regions of...

University of California - Berkeley Twelve years after a breakthrough discovery in his University of California, Berkeley, laboratory, professor of chemical engineering Jay Keasling is seeing his dream come true. On April 11, the pharmaceutical company Sanofi will launch the large-scale production of a partially synthetic version of artemisinin, a chemical critical to making today's front-line antimalaria drug, based on Keasling's discovery. The drug is the first triumph of the...

Joint BioEnergy Institute researchers develop CAD-Type tools for engineering RNA control systems The computer assisted design (CAD) tools that made it possible to fabricate integrated circuits with millions of transistors may soon be coming to the biological sciences. Researchers at the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI) have developed CAD-type models and simulations for RNA molecules that make it possible to engineer biological components or "RNA devices"...

Joint BioEnergy Institute (JBEI) Researchers Reach Milestone on the Road to Biofuels A milestone has been reached on the road to developing advanced biofuels that can replace gasoline, diesel and jet fuels with a domestically-produced clean, green, renewable alternative. Researchers with the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI) have engineered the first strains of  Escherichia coli bacteria that can digest switchgrass biomass and synthesize its...

Will we one day design and create molecules, cells and microorganisms that produce specific chemical products from simple, readily-available, inexpensive starting materials? Will the synthetic organic chemistry now used to produce pharmaceutical drugs, plastics and a host of other products eventually be surpassed by metabolic engineering as the mainstay of our chemical industries? Yes, according to Jay Keasling, chemical engineer and one of the world's foremost practitioners of metabolic...

Scientists said on Thursday that synthetic biology can be used to make instant vaccines, inexpensive medicines and even nonpolluting fuel, but it will take time. Researchers, members of Congress and an ethicist all agreed the technology does not pose immediate environmental, ethical and security concerns, but did say that everyone involved needs to keep a close eye on developments. A hearing before the House of Representatives Energy and Commerce Committee was spent mostly outlining the...

Word of the Day
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
