Full-genome sequences of multiple yeast species offer exciting possibilities for the functional analysis of yeast evolution and speciation. Lee et al. (2008) now report that hybrid sterility between two yeast species is caused by incompatibility between a nuclear-encoded mitochondrial regulatory protein and its mitochondrial-encoded target gene.

In This Issue In This Issue Clash of the titin he sarcomere is more than a complicated piece of structural machinery. According to new results by McElhinny et al. (page 125), a building block of striated muscle cells called MURF-1 may also indirectly regulate gene expression. MURF-1 localizes to sarcomeres thanks to its interaction with titin, a major structural component of the muscle sarcomer...

The introduction of lambdas in Java 8 completes the slate of statically-typed, mainstream languages with both object-oriented and functional features. The main motivation for lambdas in Java has been to facilitate stream-based declarative APIs, and, therefore, easier parallelism. In this paper, we evaluate the performance impact of lambda abstraction employed in stream processing, for a variety...
