The new whale shark genome assembly represents the best gapless chondrichthyan genome assembly yet, and comparative genomic analyses provide insights into the evolution of vertebrate genome origins, immunity, and gigantism.

Habitats of satellite-tracked blue sharks were shifted surfaceward by an oxygen minimum zone (OMZ) at depth thereby increasing their susceptibility to capture by longline fishing focused above the OMZ.

Two optically transparent substrates enable the exploration of the ecophysiology and spatiotemporal organization and activities of bacteria and fungi within heterogeneous soil-like environments.

One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

Humans perseverate on previously instructed goals in a novel multigoal reinforcement learning task, and do this to a greater extent for punishment avoidance goals.

Increased catalysis has been suggested to be an adaptive trait of enzymes to growth at lower temperature, but systematic analysis suggests that temperature exerts a weak selection pressure on enzyme rate enhancement, with observed variation arising from other evolutionary forces.

The hippocampus and neocortex engage in waves of mutual excitation wherein a sharp wave-ripple may occur at any time before, during or after the peak of the hippocampal-neocortical activation.

The development of diverse tooth shapes among vertebrates, from sharks to mammals, is a highly conserved process, utilising a similar dental signalling centre for more than 400 million years.

The tooth shape of sharks and mice are regulated by a similar signaling center despite their teeth having very different geometries.

Intermittent fasting orchestrates molecular shifts, yielding cardiovascular improvements, revealing novel cardioprotective mechanisms, and suggesting innovative pharmacological strategies for cardiovascular disease prevention and treatment.
