Scientists use new imaging technique to reveal complex microbial interactions Even the merest of microbes must be able to talk, to be able to interact with its environment and with others to not just survive, but to thrive. This cellular chatter comes in the form of signaling molecules and exchanged metabolites (molecules involved in the process of metabolism or living) that can have effects far larger than the organism itself. Humans, for example, rely upon thousands of products derived from...

Researchers at the University of California, San Diego have revealed new details about how cannibalistic bacteria identify peers suitable for consumption. The work, which employed imaging mass spectrometry, is a first step toward a broader effort to map all signaling molecules between organisms."These are the molecules that control biology," said Pieter C. Dorrestein, PhD, associate professor at UC San Diego's Skaggs School of Pharmacy and Pharmaceutical Sciences and corresponding author of a...

Using imaging mass spectrometry, researchers at the University of California, San Diego have developed tools that will enable scientists to visualize how different cell populations of cells communicate. Their study shows how bacteria talk to one another "“ an understanding that may lead to new therapeutic discoveries for diseases ranging from cancer to diabetes and allergies. In the paper published in the November 8 issue of Nature Chemical Biology, Pieter C. Dorrestein, PhD, assistant...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
