A conserved E3 ubiquitin ligase rewires carotenoid, sterol, and lipid metabolism in Xanthophyllomyces dendrorhous

Eukaryotic cells must balance the biosynthesis of sterols, lipids, and in many organisms, carotenoids, which draw on shared acetyl-CoA-derived precursors. Our study identifies the ubiquitin ligase ...

The average distances in random graphs with given expected degrees

Most of the research papers in random graph theory concern the Erdős–Rényi model 𝒢p, in which each edge is independently chosen with probability p for some given p > 0 (see ref. 3). In such random ...

Coloration strategies in peacock feathers

We report the mechanism of color production in peacock feathers. We find that the cortex in differently colored barbules, which contains a 2D photonic-crystal structure, is responsible for coloration.

Extremism does not stop at borders, and neither should our models

The Democracy Index finding holds up best. Its negative direct effect on offensive VEI (we use β for SDM coefficients throughout) survives spatial adjustment in every bivariate specification (Table 1) ...

General inverse-cube thickness scaling of projectile penetration energy in ultrathin films

Ultrathin films of widely different materials exhibit a dramatic enhancement of projectile penetration resistance under high–velocity impact. Despite extensive simulations and experiments, a unifying ...
