“Mighty Casey” Quinlan: outspoken patient activist

Casey Blacker

My research is in differential geometry. Generally speaking, I am interested in symplectic geometry, Lie groups and gauge theories, and geometric invariants relating to index theory. Specifically, I have researched the moduli space MG(M) of flat G-connections over a manifold M of dimension greater than two. These spaces, formally introduced in Section 2.1, arise naturally in physics as the spac...

Response to Helfinstein & Casey

We thank Sarah Helfinstein and B.J. Casey for raising some important issues in their commentary to our paper ‘Exciting fear in adolescence: Does pubertal development alter threat processing?’ (http://dx.doi.org/10. 1016/j.dcn.2014.01.004, this issue). In response, we welcome the opportunity to express agreement with a few of their key points, to respectfully disagree on one point, and (hopefull...

The mighty mite

storehouses of terrestrial biodiversity, but many of the more astounding species are apparent only after the closest scrutiny. Here are a few of the roughly 2000 species of mite (Arachnida: Acari) that can be found in the subtropical rainforests of Lamington National Park in southeast Queensland, Australia. The mites there range in size from 0.182 millimetres to 7 millimetres, with the minute b...

Microexons--tiny but mighty.

The landscape of alternative splicing is only beginning to unravel, and the functional consequences are often unclear. Two articles in Cell and Genome Research focus on a set of largely ignored yet highly conserved exons, microexons. These appear strongly regulated by RNA-binding proteins (RBPs) and functionally modulate protein–protein interactions with strong evidence for deregulation in auti...
