Suicidal genetically engineered microorganisms for bioremediation: Need and perspectives

Article Abstract:

The designing of safer genetically engineered organisms is discussed for environmental release with specific emphasis on the use of bacteria plasmid addiction systems to limit their survival for minimizing the anticipated risk. A novel strategy is conceptualized to construct 'Suicidal Genetically Engineered Microorganisms' by exploring/combining the knowledge of different plasmid addiction systems and inducible degradative operons of bacteria.

A twelve-step program for evolving multicellularity and a division of labor

Article Abstract:

The origin of multicellular organisms with a division of labor is one of the most interesting and complex problems in the field of evolution of development. An outline of the twelve ways to evolve multicellularity is presented. It focuses on an ancestral unicell similar to modern C. reinhardtii, which is modified to produce a small colonial organism like Gonium.

The remote roots of consciousness in fruit-fly selective attention?

Article Abstract:

A study of fruit flies and other invertebrates is presented. The research focuses on sleep and general anesthesia in these insects, which lack the brain structures traditionally associated with consciousness, such as the cortex and thalamus. Special attention is given to the relationship between attention and consciousness.
