Discovery of sexual dimorphism of the laryngeal sac in the common minke whale Balaenoptera acutorostrata

open access: yesThe Anatomical Record, EarlyView.
Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection

open access: yesBioEssays, EarlyView.
Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).
