Identification and localization of growth factor genes in the sea cucumber.

The sea cucumber is both an economically important species in Asian countries and an emerging experimental model for research studies in regeneration and medicinal bioactives. Growth factors and their receptors are known to be key components that guide tissue repair and renewal, yet validation of their presence in has not been established. We performed a targeted search of transcriptome data to elucidate conserved growth factor family and receptor genes.

Vision Guides Selection of Freeze or Flight Defense Strategies in Mice.

In prey species such as mice, avoidance of predators is key to survival and drives instinctual behaviors like freeze or flight [1, 2]. Sensory signals guide the selection of appropriate behavior [3], and for aerial predators only vision provides useful information. Surprisingly, there is no evidence that vision can guide the selection of escape strategies.
