Today’s guest author is Emma Farley, a postdoctoral researcher in Mike Levine’s lab, which recently relocated to Princeton (formerly at University of California, Berkeley). Sea squirts (Ciona intestanalis) are a classic system for the study of development. They were a favorite of early developmental biologists like Laurent Chabry, Ed Conklin, and Thomas Hunt Morgan. Over…

Allelic expression in the mouse genome is surprisingly unbalanced, according to new research published in the June issue of GENETICS. The factors that determine how a gene is expressed in a given cell are complex. After all, every mammalian cell contains two copies of each gene, and both versions of that gene, called alleles, play…

When an eastern diamondback rattlesnake bites its prey, it injects a cocktail of toxic proteins and peptides that attack on multiple fronts. These toxins destroy blood vessels, block the blood clotting cascade, cause necrosis, and inflict crippling pain. But the precise recipe for this noxious mix is generally thought to depend on where the snake…

Coral reefs around the world are “bleaching”, a threat caused by breakdown of the symbiosis between the coral animals (cnidaria) and the dinoflagellate algae that live within their cells. Yet this crucial symbiotic partnership is poorly understood. To address this knowledge gap, biologists are developing a suite of genomic tools for the sea anemone Aiptasia. This…
