Taste Perception: Cracking the Code.
Our sense of taste begins with taste buds and ends in the brain. Researchers are beginning to unravel the mechanisms and connections that lie in between.

The Strange Case of the Armored Scale Insect and Its Bacteriome.
Armored scale insects are unusual in that a part of their bodies is genetically distinct from the rest. This extraordinary phenomenon challenges the notion of identity.

Endosymbiosis: Lessons in Conflict Resolution.
Endosymbiotic bacteria live within a host species. There are many and diverse examples of such relationships, the study of which provides important lessons for ecology and evolution.

The Genetic Architecture of Parallel Armor Plate Reduction in Threespine Sticklebacks.
In stickleback populations separated over 10,000 years ago,
dramatic morphological evolution appears to result from a
relatively small number of genetic changes.

Dissection and Design of Yeast Prions.
Artificial prions - infectious, misfolded proteins - can be created by fusing the replication element of one prion to aggregation sequences from another.

Extensive Association of Functionally and Cytotopically Related mRNAs with Puf Family RNA-Binding Proteins in Yeast.
Messenger RNAs that are associated with each of the five Puf RNA-binding proteins can be grouped according to function and localization, suggesting that tagging of transcripts by specific RNA-binding proteins coordinates the control of their localization, translation, and decay.

N-Terminal Phosphorylation of the Dopamine Transporter Is Required for Amphetamine-Induced Efflux.
Using mutated dopamine transporters, the authors find that they can separate the actions of amphetamine from the normal function of the dopamine transporter.
