“…In addition to the publication of studies on feather taphonomy, scientists are teaming up to use ion beam scanning electron microscopy to investigate the preserved melanin pigments. By integrating more data with more technologies, paleocolor can provided precious insights into the behavior and ecology of extinct organisms [ 34 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ].…”

In this paper, I will briefly discuss the elements of novelty and continuity between twentieth-century paleobiology and twenty-first-century paleontology. First, I will outline the heated debate over the disciplinary status of paleontology in the mid-twentieth century. Second, I will analyze the main theoretical issue behind this debate by considering two prominent case studies within the broader paleobiology agenda. Third, I will turn to twenty-first century paleontology and address five representative research topics. In doing so, I will characterize twenty-first century paleontology as a science that strives for more data, more technology, and more integration. Finally, I will outline what twenty-first-century paleontology might inherit from twentieth-century paleobiology: the pursuit of and plea for a new synthesis that could lead to a second paleobiological revolution. Following in the footsteps of the paleobiological revolution of the 1960s and 1970s, the paleobiological revolution of the twenty-first century would enable paleontologists to gain strong political representation and argue with a decisive voice at the “high table” on issues such as the expanded evolutionary synthesis, the conservation of Earth’s environment, and global climate change.

“…This mechanism of coloration is found in many animals and insects, which spontaneously developed this technology during their evolution mainly for camouflage and prey–predator interactions. The main advantage of structural colors lies in their robustness, which can persist even after tens of millions of years, contrary to pigments or dyes that fade away quite easily.…”

Taking inspiration from complex natural phenomena such as chaos and unpredictability, as well as highly optimized organisms constituted by multitudes of interacting cells, evolutionary photonics aims at developing new sustainable technologies for renewable energy production, bioimaging, and scalable materials with advanced optical functionalities. These photonics systems integrate complex dielectric and/or metallic units into large networks of heterogeneous elements, which are entirely controlled by acting on the interactions among the different units that compose the network. This Review presents a selection of recent results in this research field, discussing advantages, challenges and perspectives of this technology in addressing global challenges in several scientific areas, ranging from broadband light energy harvesting, to scalable clean water production, early‐stage cancer detection, sensing, artificial intelligence, invisible structures, and to large‐scale optical materials with programmable functionality and robust structural coloration.

“…Nanoporous periodic structures are abundant in nature and common to many forms of life, ranging from beetles to crabs, fish and birds, [ 1–6 ] and are even found in fossils of dinosaurs. [ 7–15 ] Well‐preserved fossils, often over 500 million years old, reveal the important role of such structures in evolution. [ 7–15 ] The orderly mesoscale features evolved to enable selective and broadband reflections of solar radiation and thermal energy management under often harsh ambient conditions, in addition to other survival‐related needs.…”

One of the grand current research challenges is to improve the energy efficiency of residential and commercial buildings, which cumulatively consume more than 40% of the energy generated globally. In addition to improving the comfort of the inhabitants and mitigating the growing energy consumption problem, new building materials and technologies could provide a safe strategy for geoengineering to mitigate global climate change. Herein, recent progress in developing such advanced materials from nanocellulose, which is often derived from wood or even dirty feedstocks like waste, is reviewed. By using chemical and bacteria‐enabled processing, nanocellulose can be used to fabricate broadband photonic reflectors, thermally super‐insulating aerogels, solar gain regulators, and low‐emissivity coatings, with potential applications in windows, roofs, walls, and other components of buildings envelopes. These material developments draw inspiration from advanced energy management found in nature, such as the nanoporous photonic structures that evolved in cuticles of beetles. Fabrication of such materials takes advantage of mesoscale liquid crystalline self‐assembly, which allows for pre‐designed control of cellulose nanoparticle orientations at the mesoscale. With the potential fully realized, such materials could one day transform the current energy‐lossy buildings into energy plants on Earth and possibly even enable extraterrestrial habitats.
