One of the justifiable criticisms of human genetic studies is the underrepresentation of participants from diverse populations. Lack of inclusion must be addressed at-scale to identify causal disease factors and understand the genetic causes of health disparities. We present genome-wide associations for 2068 traits from 635,969 participants in the Department of Veterans Affairs Million Veteran Program, a longitudinal study of diverse United States Veterans. Systematic analysis revealed 13,672 genomic risk loci; 1608 were only significant after including non-European populations. Fine-mapping identified causal variants at 6318 signals across 613 traits. One-third ( = 2069) were identified in participants from non-European populations. This reveals a broadly similar genetic architecture across populations, highlights genetic insights gained from underrepresented groups, and presents an extensive atlas of genetic associations.

Glycine is an important metabolite and cell signal in diverse organisms, yet tools to visualize intracellular glycine dynamics have not been developed. In this study, diverse and bright RNA-based glycine biosensors were developed by fusing the architecturally complex glycine riboswitch with Broccoli class fluorogenic aptamers. The brightest sensor with the highest activation, glyS, and its two-dye ratiometric counterpart, Pepper-glyS, allowed for visualization of a drug-induced accumulation of endogenous glycine in live Escherichia colicells.

The genetic basis of early-stage salt tolerance in alfalfa (Medicago sativa L.), a key factor limiting its productivity, remains poorly understand. To dissect this complex trait, we integrate genome-wide association study (GWAS) and transcriptomics (RNA-seq) from 176 accessions within a machine learning based genomic prediction framework.

The persistence of tissue-specific chronic inflammation results from an interplay of genetic and environmental factors. How these factors coordinate to sustain pathology in chronic conditions like psoriasis is not well resolved. Using a Card14 murine model of psoriasis, we found that spontaneous skin inflammation reshaped not only the immune architecture in the skin but also systemic metabolites.

Antibiotic resistance genes (ARGs) in bioaerosols pose significant health hazards to humans because of their inhalability. Municipal wastewater treatment plants (MWTPs) are one of the typical sources of bioaerosol generation. However, there is a lack of clear understanding of human-associated ARGs (HA-ARGs) in bioaerosols from MWTPs.

Color polymorphism can influence the evolutionary fate of cryptic species because it increases populations' chances of survival in heterogenous or variable environments. Yet, little is known about the molecular and evolutionary mechanisms underlying the persistence of cryptic color polymorphisms, or the impact these polymorphisms have on the macroevolutionary dynamics of lineages. Here, we examine the evolutionary history of the most widespread cryptic color polymorphism in anurans, involving green and brown morphs.
