With rapid advances in optoelectronics, electrochromic materials and devices have received
tremendous attentions from both industry and academia for their strong potentials in …

The extraordinary properties of biological materials often result from their sophisticated
hierarchical structures. Through multilevel and cross-scale structural designs, biological …

Developing bioinspired camouflage materials that can adaptively change color in the visible
and infrared (IR) regions is an intriguing but challenging task. Herein, we report an emerging …

Abstract 4D printing of liquid crystal elastomers (LCEs) via direct ink writing has opened up
great opportunities to create stimuli‐responsive actuations for applications such as soft …

Bioinspired smart materials with synergistic allochroic luminescence and complex
deformation are expected to play an important role in many areas of science and …

While sleeping, many vertebrate groups alternate between at least two sleep stages: rapid
eye movement and slow wave sleep,,–, in part characterized by wake-like and synchronous …

Phase segregation is ubiquitously observed in immiscible mixtures, such as oil and water, in
which the mixing entropy is overcome by the segregation enthalpy,–. In monodispersed …

Some living organisms such as the octopus have fantastic abilities to simultaneously swim
away and alter body color/morphology for disguise and self‐protection, especially when …

Many cephalopods escape detection using camouflage. This behaviour relies on a visual
assessment of the surroundings, on an interpretation of visual-texture statistics,–and on …

There is disagreement on how best to define and investigate fear. Nature Neuroscience
asked Dean Mobbs to lead experts from the fields of human and animal affective …
