Uterine fibroids are a common condition that affects up to 80% of women in their lifetime. Nearly half of those women will experience symptoms that affect their quality of life and fertility, including severe pain and anemia. Uterine fibroids are the major reason for the removal of the uterus by hysterectomy. However, Mayo Clinic researchers recommend minimally invasive treatment alternatives to hysterectomy, in an invited clinical practice paper published in the New England Journal of Medicine.

This study presents a novel approach utilizing the concentration gradient of thiourea dissociation products to synthesize a CdNCN-CdS composite photocatalyst with an atomic-level heterostructure (NCN-Cd-S). The strong electron affinity of CdNCN and efficient electron transfer at the interface enhance photocatalytic hydrogen evolution, achieving a record-high rate of 14.7 mmol·g⁻¹·h⁻¹ under visible light, surpassing other CdS-based composites.

Researchers investigated the population characteristics of two hybrid crucian carp strains based on one nuclear gene molecular marker, Transferrin (Tf). Interestingly, the nucleotide diversity of Tf alleles in cultured populations exceeded that of wild populations, and the network and genetic structure analyses failed to distinguish between wild and cultured populations. Additionally, AMOVA analysis indicated genetic differentiation among all six populations, the majority of the genetic variation (92.00%) was observed within populations. These findings providing an alternative perspective for germplasm evaluation of hybrid varieties and crucian carp breeding.

To build nanostructures, researchers need to probe these structures’ internal architecture at various states of assembly in three dimensions. This project used several methods to produce X-ray computed tomography (CT) scans that provided record-setting, 7-nanometer resolution and information on the elements in the materials. The researchers then constructed 3-D frameworks to reveal the nanostructures’ imperfections and interfaces.

DURHAM, N.H.—(November 6, 2024)—Research led by the University of New Hampshire sheds light on how coyotes, North America’s most successful predators, are responding to various environmental pressures, including human development, hunting and competition with larger carnivores. Surprisingly, the study’s findings suggest that human hunting practices may actually contribute to increasing the number of coyotes.

Nuclear physics theorists have demonstrated that complex calculations run on supercomputers can accurately predict the distribution of electric charges in mesons, particles made of a quark and an antiquark. The calculations also help validate a method that will be used to make predictions for and analyze data from high-energy experiments at the future Electron-Ion Collider (EIC) at Brookhaven National Laboratory.
