  • Perfect absorption has been achieved in passive open quantum systems and is inherently linked to Parity-Time symmetry. Here, the authors experimentally and theoretically demonstrate a version beyond this paradigm using a system described by a non-Hermitian Hamiltonian, and providing a connection between Perfect Absorption and Hermitian subspaces.

  • The standard current–phase relation in tunnel Josephson junctions involves a single sinusoidal term, but real junctions are more complicated. The effects of higher Josephson harmonics have now been identified in superconducting qubit devices.

  • The authors fabricate a fluxonium circuit using a granular aluminium nanoconstriction to replace the conventional superconductor–insulator–superconductor tunnel junction. Their characterization suggests that this approach will be a useful element in the superconducting qubit toolkit.

  • The performance of superconducting qubits is often limited by spurious two-level systems. Now, a qubit operating as a heat engine manipulates its bath of nearby two-level systems, providing insights into their dynamics and interactions.

  • An integrated transcriptome, genome, methylome and proteome analysis of over 200 lung adenocarcinomas reveals high rates of somatic mutations, 18 statistically significantly mutated genes including RIT1 and MGA, splicing changes, and alterations in MAPK and PI(3)K pathway activity.

  • An international consortium reports the genomic sequence for ten Drosophila species, and compares them to two other previously published Drosophila species. These data are invaluable for drawing evolutionary conclusions across an entire phylogeny of species at once.

  • An integrated analysis of over 100 single-cell and single-nucleus transcriptomics studies illustrates severe acute respiratory syndrome coronavirus 2 viral entry gene coexpression patterns across different human tissues, and shows association of age, smoking status and sex with viral entry gene expression in respiratory cell populations.

  • The freshwater cnidarian Hydra is a significant model for studies of axial patterning, stem cell biology and regeneration. Its (A+T)-rich genome has now been sequenced. Comparison of this genome with those of other animals provides insights into the evolution of epithelia, contractile tissues, developmentally regulated transcription factors, pluripotency genes and more.
