Study Finds Bacteria Delay Survival Decisions
2012-11-26 14:57:56

Rice University Like a homeowner prepping for a hurricane, the bacterium Bacillus subtilis uses a long checklist to prepare for survival in hard times. In a new study, scientists at Rice University and the University of Houston uncovered an elaborate mechanism that allows B. subtilis to begin preparing for survival, even as it delays the ultimate decision of whether to “hunker down” and withdraw into a hardened spore. The new study by computational biologists at Rice and...

When faced with life-or-death situations, bacteria Рand maybe even human cells Рuse an extremely sophisticated version of "game theory" to consider their options and decide upon the best course of action, scientists reported here today. In a presentation at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, they said microbes "play" a version of the classic "Prisoner's Dilemma" game. Jos̩...

Researchers Find Pulsating Response To Stress In Bacteria

[ Watch the Video ] If the changing seasons are making it chilly inside your house, you might just turn the heater on. That's a reasonable response to a cold environment: switching to a toastier and more comfortable state until it warms up outside. And so it's no surprise that biologists have long thought cells would respond to their environment in a similar way. But now researchers at the California Institute of Technology (Caltech) are finding that cells can respond using a new kind...

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...

Bacterial spores, the most resistant organisms on earth, carry an extra coating of protection previously undetected, a team of microbiologists reports in the latest issue of the journal Current Biology. Their findings offer additional insight into why spores of the bacteria that cause botulism, tetanus, and anthrax survive methods to eradicate them. The study was conducted by researchers at New York University's Center for Genomics and Systems Biology, Loyola (Ill.) University's Medical...

Researchers demonstrate how genetic mutations and natural variations combine to produce twin spores in bacteria that normally produce only singletons How evolution acts to bridge the chasm between two discrete physiological states is a question that's long puzzled scientists. Most evolutionary changes, after all, happen in tiny increments: an elephant grows a little larger, a giraffe's neck a little longer. If those tiny changes prove advantageous, there's a better chance of passing them to...

Genetic study finds chance helps determine fate of B. subtilis bacteriaAn investigation of the genes that govern spore formation in the bacteria B. subtilis shows that chance plays a significant role in determining which of the microbes sacrifice themselves for the colony and which go on to form spores.B. subtilis, a common soil bacteria, is a well-known survivor. When running short of food, it can alternatively band together in colonies or encase itself in a tough, protective spore to wait...

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...
