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.

  • Light emission from 17 types of LEDs is observed at record-low voltages of 36–60% of the bandgaps, which cannot be explained by earlier theories. The electroluminescence-voltage curves reveal a unified mechanism for ultralow-voltage LED operation.

  • Magnetic molecules have long been seen to hold promise in magnetic sensing applications. In this paper, Serrano et al show that a single layer of a magnetic molecule, a terbium based complex, is sensitive to the local magnetic field variation of a superconducting surface on which it is deposited.

  • It is important yet challenging to elucidate the mechanism of water dissociation in bipolar membrane electrolysers. Here the authors show how water dissociation is accelerated by electric-field-focusing and catalytic effects and uncover design principles to optimize the performance.

  • Shrub encroachment trends are widespread yet complex. Here the authors demonstrate that not considering dispersal and fire leads to overestimating shrub expansion in Arctic tundra and therefore its role as carbon sink.

  • The relationship between new greenspaces and gentrification is an important one for urbanization. Here the authors show a positive relationship for at least one decade between greening in the 1990s–2000s and gentrification that occurred between 2000–2016 in 17 of 28 studied cities in North America and Europe.

  • DNA barcoding methods for the analysis of clonal heterogeneity in cancer have been limited in terms of throughput and practical requirements. Here, the authors develop SunCatcher, a rapid and sensitive barcoding approach for live single-cell clonal evolution analysis, and use this method to study breast cancer cell populations.

  • Emerging SARS-CoV-2 variants raise concerns on protective immunity. Here the authors show that convalescent sera from people infected with Alpha, Beta, Gamma or Delta show a significant drop of Omicron-BA.1 neutralization and that vaccine-breakthrough infections with Omicron-BA.1 or Delta result in robust neutralization for both Delta and Omicron-BA.1.

  • Although deep learning-based computer-aided diagnosis systems have recently achieved expert level performance, developing a robust model requires large, high-quality data with annotations. Here, the authors present a framework which can improve the performance of vision transformer simultaneously with self-supervision and self-training.

Here authors show that type 3 innate lymphoid cells with activated phenotypes are found in the sputum and blood of smokers in higher frequencies, which might result in the aggravation of asthma.
