New Constraints on the Melting Temperature and Phase Stability of Shocked Iron up to 270 GPa Probed by Ultrafast X-Ray Absorption Spectroscopy.

Studying the properties and phase diagram of iron at high-pressure and high-temperature conditions has relevant implications for Earth's inner structure and dynamics and the temperature of the inner core boundary (ICB) at 330 GPa. Also, a hexagonal-closed packed to body-centered cubic (bcc) phase transition has been predicted by many theoretical works but observed only in a few experiments. The recent coupling of high-power laser with advanced x-ray sources from synchrotrons allows for novel approaches to address these issues.

Seroprevalence of Brucellosis in Livestock and Farmers' Choice of Milk Marketing Channels in Rwamagana District, Rwanda.

Brucellosis remains an endemic disease in livestock populations in Rwanda, but the prevalence of the disease varies by geographic region. The common use of informal milk marketing channels represents a health hazard to humans when milk from Brucella-infected cows from one or more households is mixed with milk from other households for human consumption. In Rwanda, knowledge about the burden of brucellosis in livestock and factors associated with farmers' choice of milk marketing channels is very limited.

Permanent Neonatal Diabetes with High Insulin Requirements Due to a New Variant in the Gene.

Neonatal diabetes is an infrequent disorder that may present as transient, permanent, or syndromic. It is most commonly caused by pathogenic variants involving the ABCC8, KCNJ11, and INS genes. To describe a neonate with permanent diabetes mellitus due to a previously unreported variant in the INS gene, outlining the diagnostic complexities, therapeutic interventions, and related clinical challenges.

Variation in brain aging: A review and perspective on the utility of individualized approaches to the study of functional networks in aging.

Healthy aging is associated with cognitive decline across multiple domains, including executive function, memory, and attention. These cognitive changes can often influence an individual's ability to function and quality of life. However, the degree to which individuals experience cognitive decline, as well as the trajectory of these changes, exhibits wide variability across people.
