Pill Packing 100 Billion Designer Bacteria Could Be Tested Next Year

Bacteria are among the oldest life forms on Earth and exist nearly everywhere; in the soil, water, deep in the earth’s crust and in our own bodies. Actually, there are at least as many bacterial cells in the human body as human cells. Bacteria tend to get a bad rap, but now, armed with new research on the bacterial world (or microbiome) in our bodies, we are starting to understand how important a role microorganisms… read more

Harvard Biologists Just Demonstrated the Most Extensive Reengineering of a Genome Yet

Researchers at Harvard Medical School have “radically rewritten” the genome of bacteria E. coli. The team has replaced 7 of its 64 codons (3-letter sequences which correspond usually to a single animo acid.) The lab, led by George Church, had already proven it is possible to recode single amino acids, but this project is the first to introduce so many functional changes to a genome.  Why is this such a big step? Church says it demonstrates the kind of… read more

Smartphone-Sized Genetic Sequencer Transcribes Entire Bacterial Genome

Scientists first transcribed the genome—or complete genetic code—of a free living organism in 1995. Sequencing the bacterium H. Influenzae took a little over a year, cost about $1 million, and… read more
