Barrierless nucleation in glassy precursors drives zeolite formation
Zeolites are crystalline, microporous silicates widely used in catalysis and separations, yet the molecular mechanisms of their formation remain unresolved. Experiments indicate that hydrothermal synt...
Tppp3 determines basal body positioning and identity of respiratory cilia via microtubule assembly and sphingolipid homeostasis
Cilia are hair-like organelles that protrude from the cell surface. In mammals, tracheal multiciliated cells (MCCs) play an important role in elimination of hazardous microorganisms by driving a unidi...
Forests weather soil cations and lose them to streams
Some parasites like it hot, some don’t
Dynamic control of phase for tunable structural colors
Structural coloration offers many advantages over conventionally used pigment-based colors due to their nontoxic, fade-resistant, and environmentally friendly nature. These colors arise from the struc...
A theory of ecological invasions and its implications for eco-evolutionary dynamics
Predicting the outcomes of species invasions is a central goal of ecology, a task made especially challenging due to ecological feedbacks. To address this, we develop a general theory of ecological in...
Mysterious illnesses have supernatural and ritualistic cures: Evidence from 3,655 century-old Irish folk cures
Why and when do people draw upon religious and supernatural solutions to problems? Cognitive scientists and anthropologists have proposed a range of answers, stressing religion and ritual’s capacity t...
Regulation of eukaryotic-like cell cycle progression in archaea is coming into focus
Lineage tracing of both quiescent G0 and active Hoxb5+ LT-HSCs that actively contribute to homeostatic mouse hematopoiesis
Studying the lineage commitment and differentiation potential of long-term hematopoietic stem cells (LT-HSCs) is important to understand the dynamics of hematopoiesis. A central question concerns whic...
Stochastically evolving graphs via edit semigroups
We investigate a randomly evolving process of subgraphs in an underlying host graph using the spectral theory of semigroups related to the Tsetlin library and hyperplane arrangements. Starting with so...
Rice farming for climate change adaptation in the Northeastern United States
In response to challenges posed by climate change, rice farming emerges as a strategic adaptation in the agriculture sector in the northeastern United States. Cultivating rice can diversify farming pr...
Cell envelope maintenance by PhoP is essential for <i>Mycobacterium tuberculosis</i> methylglyoxal resistance
During Mycobacterium tuberculosis infections bacteria are engulfed by macrophages, a main line of defense against invading pathogens. Upon activation, macrophag...
