The rapid evolution of durophagy in lungfish

Xindong Cui et al. describe exceptionally preserved fossils of lungfish (air-breathing fish) from the Early Devonian that show early adaptations to durophagy, or the consumption of hard-shelled prey.

  • Rapid investigation of chemical reactions is a challenge in bio-medical analysis. Here, the authors demonstrate sensitive in-situ real-time reaction-monitoring of conformational changes in protein solution, based on a fingertip-sized mid-IR lab-on-a-chip.

  • Liquid metals that have enormous surface tension are difficult to pattern into films. Here, authors report the spontaneous and selective wetting of a gallium-based liquid metal, which is induced by imbibition on a micro-structured metallized substrate.

  • Here, the authors find the missing link for soliton microcombs that exist at the boundary where the group velocity dispersion of light changes sign: zero-dispersion solitons. The resulting microresonator frequency comb, based in Si3N4, spans almost an octave.

  • Dynamic remodeling of the actin cytoskeleton underlies cell movement, but is challenging to characterize at the molecular level. Here, the authors present a method to extract actin filament velocities in living cells, and compare their results to current models of cytoskeletal dynamics.

  • In this study, the authors report that anionic nanoplastics can harness the paracellular space of endothelial cells and puncture blood vasculature ex vivo and in vivo, thereby entailing new environmental and health implications.

  • Nanosized Pd-based catalysts are widely used in the direct hydrogen peroxide (H2O2) synthesis from H2 and O2, while the selectivity and yield of H2O2 remain inferior. Here, a remarkable H2O2 yield of 115 mol/gPd/h and H2O2 selectivity higher than 99% are reported using a Pd single-atom catalyst for the direct synthesis of H2O2.

  • Marine protected areas are proposed to protect elasmobranchs (sharks, skates, and rays) but the fishing impact from small-scale fisheries in these areas is unknown. From 1256 fishing operations carried out in partially protected and unprotected areas in six Mediterranean countries, this study shows that catches were higher in partially protected areas than in unprotected areas, indicating poor small-scale fisheries management as a threat for these species.

  • The optoelectronic performance of wide-bandgap semiconductors often cannot compete with that of their defect-tolerant small-bandgap counterpart. Here, the authors outline three main challenges to overcome for mitigating the impact of defects in wide-bandgap semiconductors.

  • A plethora of work has shown that AI systems can systematically and unfairly be biased against certain populations in multiple scenarios. The field of medical imaging, where AI systems are beginning to be increasingly adopted, is no exception. Here we discuss the meaning of fairness in this area and comment on the potential sources of biases, as well as the strategies available to mitigate them. Finally, we analyze the current state of the field, identifying strengths and highlighting areas of vacancy, challenges and opportunities that lie ahead.

  • Kv3 channels enable neurons to fire at very high frequencies (>100 Hz) which is fundamental to brain development and our ability to make sense of the world at large. Cryo-EM and structure-function studies by Chi et al. now uncover Kv3 channel gating mechanisms and support new precision medicine approaches for CNS diseases.
