About the cover

This special issue of Nature explores some of the concerns of early-career scientists by attempting to give them a voice. We talk to young researchers battling to establish their labs, hoping to innovate and at the same time build a career when so much emphasis is placed on paper counts. And at a time when career progression is hampered by a global postdoc glut, scarce funding and the disappearance of tenure-track posts, we argue in our Editorial that it is up to everyone in science — young and old — to ensure that the next generation of researchers is not lost.

    • Let researchers try new paths

      Demand for steady output stymies discovery. To pursue the most important research, scientists must be allowed to shift their focus, say Tolu Oni and colleagues.

    • Fewer numbers, better science

      Scientific quality is hard to define, and numbers are easy to look at. But bibliometrics are warping science — encouraging quantity over quality. Leaders at two research institutions describe how they do things differently.

      Simultaneous measurement of two incompatible observables in a superconducting qubit placed in a cavity shows that the quantum dynamics of the system is governed by the uncertainty principle and that the wavefunction collapse is replaced by persistent diffusion.

      Birds make sound in the syrinx, a unique vocal organ situated deep in the chest, but little is known about the evolution of this structure; a fossilized Cretaceous age syrinx from Antarctica is described from a species that might have been capable of making a goose-like honking sound.

      Here, leukaemia cells are followed by intravital microscopy as they infiltrate mouse bone marrow and respond to chemotherapy, revealing that at all stages analysed they are highly motile and do not display any associations with particular bone marrow sub-compartments.

      Inactivation of three Tet genes in mice leads to gastrulation phenotypes similar to those in embryos with increased Nodal signalling, revealing a functional redundancy of Tet genes and showing balanced and dynamic DNA methylation and demethylation is crucial to regulate key signalling pathways in early body plan formation.
