A 3D view of early mammals p.32

The unexpected discovery of a nearly complete skull from the Early Cretaceous epoch that has been preserved in three dimensions provides profound insights into the evolution and biogeography of early mammals.

A fresh approach to stellar benchmarking p.33

An avalanche of data is about to revolutionize astronomy, but the options for validating those data have been limited. High-precision measurements from the Hubble Space Telescope enable a much-needed alternative option.

Tropical cyclones are becoming sluggish p.36

The speed at which tropical cyclones travel has slowed globally in the past seven decades, especially over some coastlines. This effect can compound flooding by increasing regional total rainfall from storms.

Motion processing picks up speed in the brain p.38

Recordings of individual neurons in the mouse brain reveal a main mechanism for motion processing in the primary visual cortex. These findings are likely to have implications for other species.

Two artificial synapses are better than one p.39

Emerging nanoelectronic devices could revolutionize artificial neural networks, but their hardware implementations lag behind those of their software counterparts. An approach has been developed that tips the scales in their favour.

Molecular tuning of electroreception in sharks and skates p.122

Shark and skate electrosensory cells use specific potassium channels to support either indiscriminate detection of electrical stimuli or selective frequency tuning, respectively, demonstrating adaptation of sensory systems through discrete molecular modifications.

The coding of valence and identity in the mammalian taste system p.127

The identity and hedonic value of tastes are encoded in distinct neural substrates; in mice, the amygdala is necessary and sufficient to drive valence-specific behaviours in response to bitter or sweet taste stimuli, and the cortex can independently represent taste identity.
