Novel brainstem organotypic cultures that generate rhythmic respiratory motor activity reveal the neural networks that control breathing and a new pathway in the hypercapnic response.
Microscopic and biochemical analysis show that the stress-activated MAP kinase pathway targets the formin For3 to modulate actomyosin ring integrity in response to environmental cues.
Two members of a widely studied family of chemoreceptors, the "orphan" chemoreceptor IR21a and its putative co-receptor IR25a, act together to mediate cool sensation in fruit fly larvae.
