Editor’s summaryMany of the hole-transport materials used in inverted perovskite solar cells are either too hydrophobic to wet perovskite precursors or can react with the perovskite, which causes the buried interface between these layers to develop performance-limiting defects. Zhang et al.

Editor’s summaryAnyone who has ever packed away rope without coiling it properly knows how easily it gets tangled and how difficult it can be to untangle. By contrast, California blackworms will migrate into a tangled ball over the course of minutes to regulate temperature or moisture but then disentangle and scatter within milliseconds upon sensing danger. Patil et al.

White et al. (1) did not test their model for its ability to simultaneously capture ontogenetic patterns of growth, respiration, feeding, and reproduction, but doing so reveals important issues with the model’s formulation. Energy budget models usually start with energy in food that, following assimilation, is either fixed in new biomass (eggs/soma), excreted, or dissipated through maintenance and biosynthesis (2).

AbstractWhite et al. (Science 377, p. 834–839, 2022) propose that reproduction reduces the somatic growth of animals. This contradicts the common observations that non-reproducing adults are not larger than those that reproduced as well as the very example the authors provide of a fish that reproduces while its growth continues to accelerate, which is common in larger fish.

As a scientist and a leader, Willie E. May is powered by the opportunity to be part of something greater than himself. “I wake up each morning eager to help others, and especially young people, be a small part of humanity’s striving to understand nature and create a better world,” May told members of the American Association for the Advancement of Science ahead of the organization’s 2023 election, in which May was a candidate for president-elect.

Earthquakes A two-stage earthquake in the AleutiansKevin FurlongThe destructive behavior of great earthquakes in subduction zones, such as in Japan in 2011, depends on details of the earthquake slip. A slip at shallow depth is the dominant driver of tsunami. Using recently developed seafloor geodetic instrumentation, Brooks et al. found that the deeper slip of the July 2021 magnitude 8.2 Chignik, Alaska earthquake was followed 2.5 months later by a second stage of (aseismic) slip.

Editor’s summaryDNA replication is challenged by obstacles, including DNA damage, that impede synthesis and threaten genome stability. A common response to this replication stress is replication fork reversal, in which parental DNA reanneals and a new daughter strand duplex is formed. Liu et al.

AbstractFroese and Pauly argue that our model is contradicted by the observation that fish reproduce before their growth rate decreases. Kearney and Jusup show that our model incompletely describes growth and reproduction for some species. Here we discuss the costs of reproduction, the relationship between reproduction and growth, and propose tests of models based on optimality and constraint.

Editor’s summaryYeast cells have a transcriptional toggle switch that leads them to die by one of two fates: One causes death by nucleolar decline, the other by mitochondrial decay. By rewiring this transcriptional switch into a negative-feedback loop, Zhou et al. were able to cause yeast cells to oscillate between the two states and increase their life span by 82% (see the Perspective by Salis).

Editor’s summaryBacterial spores are able to resist heat, desiccation, irradiation, organic solvents, and antibiotics and can remain metabolically inactive for decades. Nevertheless, an encounter with nutrients triggers exit from dormancy and resumption of growth within minutes. How these inert bodies monitor their environment and trigger germination remains unclear. Working with the bacterium Bacillus subtilis, Gao et al.
