University of Washington Uneven distribution of certain mechanisms during cell division creates diversity that can enhance a bacterial population's survival Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways. This phenomenon is crucial in the bacteria's struggle for survival. The more diversity a population of bacteria has, the more likely it will contain individuals able to take advantage of...

In their natural environment bacteria develop by forming communities of micro-organisms called biofilms that afford them greater resistance. These biofilms on farms and premises where food is processed lead to considerable economic losses besides being a potential source of contamination and transmission of the pathogen. In her PhD thesis,VioletaZorraquino-Salvo has studied a specific protein type that activates the formation of biofilm in Salmonella and regulates bacterial...

Key protein's double wing-like crystal structure captures secreted molecules from invading pathogens, activating the body's powerful immune response Researchers at Weill Cornell Medical College have unlocked the structure of a key protein that, when sensing certain viruses and bacteria, triggers the body's immediate immune response. In the journal Molecular Cell, scientists describe the double wing-like crystal structure of this key protein, known as STING, which is a soldier on the...

Regulator is distributed unevenly during cell division to make two functionally and structurally different cells Some species of bacteria perform an amazing reproductive feat. When the single-celled organism splits in two, the daughter cell - the swarmer - inherits a propeller to swim freely. The mother cell builds a stalk to cling to surfaces. University of Washington (UW) researchers and their colleague at Stanford University designed biosensors to observe how a bacterium gets the message...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
