For population biologist Bruce Levin, opening the incubator to see how yesterday’s experiment worked is his ideal way to start the day. That anticipation has kept the Emory University professor of biology excited about his research on the population and evolutionary biology of bacteria for more than 40 years, and motivated a shift in interest from multicellular organisms to bacteria. Anything t...

A cellular automata rule for the majority classification task was evolved using genetic programming with automatically defined functions. The genetically evolved rule has an accuracy of 82.326%. This level of accuracy exceeds that of the Gacs-Kurdyumov-Levin (GKL) rule, all other known human-written rules, and all other rules produced by known previous automated approaches. Our genetically evol...

We herein report a preterm infant who presented with features suggestive of Alagille syndrome, but microarray showed findings consistent with WS. This further extends the phenotype of WS and emphasizes the need for microarray analysis.
