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...

Scientists develop new 'map' within sea creatures to help pinpoint source of potent compounds promising to treat diseases With the number of terrestrial sources that yield novel treatments for human disease decreasing year by year, the oceans have been tapped as a promising resource for discovering new natural biomedicines. Two studies by scientists at UC San Diego, each utilizing mass spectrometry in novel ways, have helped narrow the gap in identifying potent natural compounds from the sea...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
