Tendencies toward triadic closure: Field experimental evidence
Empirical social networks are characterized by a high degree of triadic closure (i.e., transitivity, clustering): network neighbors of the same individual are also likely to be directly connected. It...
FtsZ-mediated spatial–temporal control over septal cell wall synthesis
FtsZ, the tubulin-like GTPase, is the central organizer of the bacterial divisome, a macromolecular complex that synthesizes new septal cell wall (made of septal peptidoglycan, sPG) to allow cell wall...
Rising surface salinity and declining sea ice: A new Southern Ocean state revealed by satellites
For decades, the surface of the polar Southern Ocean (south of 50°S) has been freshening—an expected response to a warming climate. This freshening enhanced upper-ocean stratification, reducing the up...
The epigenetic impacts of pubertal acceleration following early caregiver disruptions
A stable caregiving environment early in life is essential for children’s development, and disruptions have the potential to impact biological processes. Using data from the Bucharest Early Interventi...
Jurassic constraints on the chaotic Mars–Earth eccentricity cycle linked to the volcanically induced Jenkyns event
Solar system gravitational interactions are embedded in Earth’s record of climate, providing a way to bypass the 60 Myr limit imposed by chaos. Presently with a 2.4 Myr period, the Mars–Earth beat cyc...
A transcriptomic, proteomic, and functional genetic atlas dissects neurofibromin function in the peripheral nervous system
The NF1 tumor suppressor gene is recurrently mutated in human cancers and is associated with the neurofibromatosis type 1 (NF-1) cancer predisposition syndrome....
The importance of scientists’ intellectual humility for communicating effectively across ideological and identity-based divides
Growing identity-based and partisan gaps in confidence in scientists and scientific institutions call for novel approaches to science communication. In this perspectives piece, we focus on the need fo...
