MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of generations.

(Phys.org)—A team of US biologists has found that the chytrid fungus, believed to be responsible for amphibian deaths worldwide, also infects and kills crayfish. In their paper published in the Proceedings of the National ...
(Phys.org)—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 ...
