Stellar feedback and triggered star formation in the prototypical bubble RCW 120.

Radiative and mechanical feedback of massive stars regulates star formation and galaxy evolution. Positive feedback triggers the creation of new stars by collecting dense shells of gas, while negative feedback disrupts star formation by shredding molecular clouds. Although key to understanding star formation, their relative importance is unknown.

Cyclic di-AMP Acts as an Extracellular Signal That Impacts Biofilm Formation and Plant Attachment.

There is a growing appreciation for the impact that bacteria have on higher organisms. Plant roots often harbor beneficial microbes, such as the Gram-positive rhizobacterium , that influence their growth and susceptibility to disease. The ability to form surface-attached microbial communities called biofilms is crucial for the ability of to adhere to and protect plant roots.

Natural-Product Antibiotics: Cues for Modulating Bacterial Biofilm Formation.

Cell-cell communication enables bacteria to coordinate their behavior through the production, recognition, and response to chemical signals produced by their microbial neighbors. An important example of coordinated behavior in bacteria is biofilm formation, where individual cells organize into highly complex, matrix-encased communities that differentiate into distinct cell types and divide labor among individual cells. Bacteria rely on environmental cues to influence biofilm development, including chemical cues produced by other microbes.

Draft Genome Sequence of Bacillus luciferensis Isolated from Soil.

Bacillus luciferensis is a Gram-positive, facultatively anaerobic, motile rod. Here, we report the first draft genome sequence, to our knowledge, of a B. luciferensis strain (CH01), which will provide useful information for Bacillus and soil bacteria research.
