AbstractIce-jam floods are a unique yet understudied hydrological hazard, occurring in cold-region rivers when upstream thawing and downstream freezing create ice blockages. Despite their severe impacts, their atmospheric drivers and future trends remain unclear. Using a 160-year documentary record, historical reanalysis datasets, and statistical modeling, we examine the climatic and hydrological controls of ice-jam floods in the lower Yellow River, one of the world’s most flood-prone rivers.

Introduction Starch provides ~50% energy source for human (Miao and Hamaker, 2021). Starch granules with semi-crystalline structure are the primary form of starch, which are composed of two basic glucose polymers: amylose and amylopectin. Amylose is synthesized by granule bound starch synthase (GBSS), whereas amylopectin is synthesized by three classes of enzymes: starch synthases (SS), starch branching enzymes (SBE) and debranching enzymes (DBE) (Huang et al., 2021).

Section snippetsMetabolic adaptations: challenges of, and opportunities for, HSCs and LSCsHSCs have long-term self-renewal capabilities and replenish the blood system throughout an individual's lifetime. Quiescence in HSCs maintains their genomic integrity and prevents damage to their stemness. Historically, replication stress, marked by the switch from quiescence to the activation cell cycle stage, was believed to be the primary threat to HSC function [1].

AbstractThe Moon has a tenuous atmosphere produced by space weathering. The short-lived nature of the atoms surrounding the Moon necessitates continuous replenishment from lunar regolith through mechanisms such as micrometeorite impacts, ion sputtering, and photon-stimulated desorption. Despite advances, previous remote sensing and space mission data have not conclusively disentangled the contributions of these processes.

AbstractIn noncentrosymmetric superconductors, superconducting and normal conductions can interchange on the basis of the current flow direction. This effect is termed a superconducting diode effect (SDE), which is a focal point of recent research. The broken inversion and time-reversal symmetry is believed to be the requirements of SDE, but their intrinsic role has remained elusive. Here, we report strain-controlled SDEs in a layered trigonal superconductor, PbTaSe2.

AbstractChromatin marks are associated with transcriptional regulatory activities. However, very few lncRNAs have been characterized with the role in regulating epigenetic marks, largely due to the technical difficulty in identifying chromatin-associating RNA. Current methods are largely limited by the availability of ChIP-grade antibody and the crosslinking, which generates high noise.

AbstractWe demonstrate complete control over dynamics of a single superconducting vortex in a nanostructure, which we coin the Single Vortex Box. Our device allows us to trap the vortex in a field-cooled aluminum nanosquare and expel it on demand with a nanosecond pulse of electrical current. Using the time-resolving nanothermometry we measure 4·10-19 joules as the amount of the dissipated heat in the elementary process of the single-vortex expulsion.

AbstractUnprecedented precipitation deficits in the 2022–2023 growing season across the primary wheat-producing region in the United States caused delays in winter wheat emergence and poor crop growth. Using an integrated approach, we quantitatively unraveled a 37% reduction in wheat production as being attributable to both per–harvested acre yield loss and severe crop abandonment, reminiscent of the Dust Bowl years in the 1930s.

AbstractSickle cell disease is a growing health burden afflicting millions around the world. Clinical observation and laboratory studies have shown that the severity of sickle cell disease is ameliorated in individuals who have elevated levels of fetal hemoglobin. Additional pharmacologic agents to induce sufficient fetal hemoglobin to diminish clinical severity is an unmet medical need.
