Bacteria collaborate to sense arsenic

Quorum Sensing: Bacteria Talk Sense

Cell communication in bacteria occurs through a vernacular of small diffusible chemical signals that impact gene regulation during times of high cell density. This form of intercellular signaling, known as quorum sensing, optimizes the metabolic and behavioral activities of a community of bacteria for life in close quarters. Quorum sensing is best characterized as a means of communication withi...

How to Collaborate

This paper argues that collaboration in scientific and other fields requires a substantial amount of procedural knowledge about how to collaborate. It discusses how scientists collaborate, how they learn to collaborate, and why they collaborate. Knowledge how does not always reduce to knowledge that, and collaboration has many purposes besides the pursuit of power and resources. The relative sc...

An effort to make sense of antisense transcription in bacteria

Analysis of bacterial transcriptomes have shown the existence of a genome-wide process of overlapping transcription due to the presence of antisense RNAs, as well as mRNAs that overlapped in their entire length or in some portion of the 5'- and 3'-UTR regions. The biological advantages of such overlapping transcription are unclear but may play important regulatory roles at the level of transcri...

How to Collaborate between Threshold Schemes

Threshold schemes have been used to protect secrets by distributing shares to participants. To protect two secrets, we can use two separate traditional schemes, say, a (t1, n1) scheme and a (t2, n2) scheme. If there are u (≤min(t1, t2) ) participants involved in both schemes, each of these u participants must keep two different shares. This paper proposes a method that allows each common partic...
