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...

[ Video: M. Xanthus Ripples — Predation ] | [ Video: Predatory Bacterial Crowdsourcing ] Alan McStravick for redOrbit.com - Your Universe Online Waves at the beach are relaxing. Waves at a baseball game are fun. Waves in the bacterial world are deadly. This is according to a study offered by scientists from Rice University and the University of Texas Health Science Center at Houston Medical School. The study´s findings show one of the world´s smallest predators, the...

Microcinematic image analysis finds existing theories of bacterial self-organization are lacking In a surprising new study, researchers using image-analysis methods similar to those employed in facial-recognition software have made a startling discovery that rules out the two main theories scientists had created to explain how bacteria self-organize into multicellular aggregate mounds. The study by researchers from Rice University and the University of Georgia appears online this week in the...

Computer model finds probable genetic mechanism for TB dormancy An examination of a portion of the tuberculosis genome that responds to stress has allowed Rice University bioengineers Oleg Igoshin and Abhinav Tiwari to zero in on a network of genes that may "switch" the disease into dormancy. The bacteria that cause tuberculosis (TB), Mycobacterium tuberculosis, can transition into a dormant state to ward off attacks from antibiotics and the immune system. A new report from Igoshin and Tiwari...

Rice bioengineers define relationship between key regulatory proteins With thousands of scientists across the globe searching for ways to use adult stem cells to fight disease, there's a growing emphasis on finding the "master regulators" that guide the differentiation of stem cells. New research from Rice University and the University of Cambridge suggests that a closely connected trio of regulatory proteins fulfills that role in hematopoietic stem cells (HSCs), the self-renewing cells the...

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...
