Team probes mysteries of oceanic bacteria
Microbes living in the oceans play a critical role in regulating Earth's environment, but very little is known about their activities and how they work together to help control natural cycles of water, carbon and energy. A team of MIT researchers led by Professors Edward DeLong and Penny Chisholm is trying to change that. Borrowing gene sequencing tools developed for sequencing the human ...

Small RNAs yield great amounts of data from ocean microbe samples
An ingenious new method of obtaining marine microbe samples while preserving the microbes' natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs -- snippets of RNA that act as switches to regulate gene expression in these single-celled creatures. Before now, small RNA could only be studied in lab-cultured microorganisms; the discovery of its presence ...

Gas sensors `see` through soil to analyze microbial interactions
Rice University researchers have developed gas biosensors to “see” into soil and allow them to follow the behavior of the microbial communities within. In a study in the American Chemical Society’s journal Environmental Science and Technology, the Rice team described using genetically engineered bacteria that release methyl halide gases to monitor microbial gene expression in ...
