Promoting Identity Development, Multicultural Attitudes, and Civic Engagement Through Ethnic Studies: Evidence From a Natural Experiment.

This study used a natural experiment design to examine the impact of ethnic studies courses on students' ethnic-racial identity (ERI) development, multicultural attitudes, and civic engagement during the 2021-2022 school year in Minneapolis, MN (N = 535; 33.5% White, 29.5% Black, 21.

Conformational diversity in class C GPCR positive allosteric modulation.

The metabotropic glutamate receptors (mGlus) are class C G protein-coupled receptors (GPCR) that form obligate dimers activated by the major excitatory neurotransmitter L-glutamate. The architecture of mGlu receptor comprises an extracellular Venus-Fly Trap domain (VFT) connected to the transmembrane domain (7TM) through a Cysteine-Rich Domain (CRD). The binding of L-glutamate in the VFTs and subsequent conformational change results in the signal being transmitted to the 7TM inducing G protein binding and activation.

Census Tract Rurality, Predominant Race and Ethnicity, and Distance to Lung Cancer Screening Facilities : An Ecological Study.

Background: The U.S. Preventive Services Task Force recommends annual lung cancer screening (LCS) for adults who meet specific age and smoking history criteria.

Advancing macromolecular structure determination with microsecond X-ray pulses at a 4th generation synchrotron.

Serial macromolecular crystallography has become a powerful method to reveal room temperature structures of biological macromolecules and perform time-resolved studies. ID29, a flagship beamline of the ESRF 4th generation synchrotron, is the first synchrotron beamline in the world capable of delivering high brilliance microsecond X-ray pulses at high repetition rate for the structure determination of biological macromolecules at room temperature. The cardinal combination of microsecond exposure times, innovative beam characteristics and adaptable sample environment provides high quality complete data, even from an exceptionally small amount of crystalline material, enabling what we collectively term serial microsecond crystallography (SµX).

Groundwater Ages in Intertill and Buried Valley Aquifers in Saskatchewan, Canada.

Continental glaciations during the Pleistocene Epoch created complex systems of aquifers and aquitards across many northern regions of the Earth. The low hydraulic conductivities of glacial till aquitards suggest that limited recharge will reach the underlying aquifers, potentially preserving old groundwaters. Here, we characterize the recharge history in intertill and buried valley aquifers in Saskatchewan, Canada using C, H, He δH, δO, and major ions.
