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.

  • We’re calling Early Career Researchers wishing to hone their peer review skills to join our training programme. This is an opportunity to learn about the peer review process, guided by professional editors. We are especially eager to connect with ECRs from a diverse set of backgrounds and geographical locations. All disciplines welcome and review experience is not required. Closing date 10th July.

  • Harmonic measurements have been used extensively in ferromagnetic/heavy metal heterostructures to characterize the magnetization dynamic; however, it has remained unclear about whether such techniques could be applied to antiferromagnetic devices. Here, Cheng et al demonstrate such a harmonic measurement approach in an antiferromagnet.

  • Self-assembly and molecular recognition usually depend on strong, directional non-covalent interactions but also topography can play a role in the formation of supramolecular constructs which makes it nearly impossible to discern the potential of shape and motion in the creation of complexity. Here, the authors demonstrate that long-range order in supramolecular constructs can be assisted by the topography of the individual units even in the absence of highly directional interactions.

  • The lightning's nature is that different-polarity leaders extend in air. Only negative leaders' development was previously associated to floating plasma. We found that the floating plasma could also lead the positive leader stepwise development.

  • Habitability of exoplanet’s deepest oceans could be limited by the presence of high-pressure ices at their base. New work demonstrates that efficient chemical transport within deep planetary ice mantles is possible through significant salt incorporation within the high-pressure ice.

  • Writing in Nature communications, Seo and collaborators presented PICASSO as a method to achieve 15-color imaging of spatially overlapping proteins using no reference emission spectra in a single staining and imaging round. This accessible tool has the potential to be applied to diverse applications within the spatial biology field without neglecting accuracy.
