Leela McKinnon, Dr. David Samson and colleagues published an article entitled Technological infrastructure, sleep, and rest-activity patterns in a Kaqchikel Maya community in PLOS ONE. The study results suggest that industrialization does not inherently reduce characteristics of sleep quality; instead, the safety and comfort afforded by technological development may improve sleep, and an intermediate degree of environmental exposure and technological buffering may support circadian rhythm strength and stability.

Dr. Frank Wendt and colleagues published an article in the journal JAMA Network Open investigating genetic variants associated with maximum habitual alcohol intake. Their work contextualizes the spectrum of alcohol consumption and problematic use to further solidify the notion that recreational consumption is fundamentally different than problematic reliance on alcohol.

Dr. Frank Wendt and collaborators at Yale, the University of Barcelona, and University of Rome “Tor Vergata” recently published an article in the journal BMC Biology describing the contribution of Neanderthal and Denisovan introgression to the common variant genetic architectures of complex traits in modern humans. Their work highlights a specific contribution of Denisovan introgression in East Asian populations with respect to circulating biomarkers. Link: Denisovan and Neanderthal archaic introgression differentially impacted the genetics of complex traits in modern populations(Posted November 9, 2022)


Dual MD/MBA candidate Andrea Quintero Reis and UTM undergraduate Brendan Newton, trainees in Dr. Frank Wendt’s research group, recently posted a preprint to medRxiv describing a genomic-structural equation model of the thoughts and behaviors associated with death by suicide. Their work demonstrates the cross-ancestry portability of a suicidality polygenic score and shows one path forward for statistically powerful genetic studies of sensitive self-report data.

Professor Monica Ramsey and her collaborators have a new study published in the Journal of Archaeological Science. The study shows that it is possible to automate the detection and classification of phytoliths with a high-level of accuracy, up to a species level. This method has the potential to allow the development of much larger analytical datasets in a fraction of the time than was previously feasible, as well as to assure consistency in phytolith identification and increase the validity of sample analysis. (Posted October 11, 2022)


Dr. Trevor Orchard is among a team of collaborators on a research project entitled “Iroquoian-Pikeperch Interactions on the North Shore of Lake Ontario: A Genetic Perspective” which is funded by a SSHRC Insight Development Grant recently awarded to Dr. Thomas Royle (Simon Fraser University). This project seeks to better understand past use of and the historical ecology of prominent fish species, walleye and sauger, in southern Ontario through a program of small scale ancient DNA and isotopic analysis of fish remains from legacy faunal assemblages from past archaeological work in the region. (Posted October 6, 2022)


Dr. Trevor Orchard, Dr. Alicia Hawkins, and their collaborators have just published a paper entitled “Considering passenger pigeon abundance and distribution in the Late Woodland zooarchaeological record of southern Ontario, Canada”. The paper, published in the International Journal of Osteoarchaeology, demonstrates that passenger pigeon remains are consistently among the most abundant bird remains in archaeological sites dating from roughly the 12th to the 17th centuries CE, although their abundance varies through time. (Posted September 27, 2022)

Disorders with internalizing symptoms (such as PTSD, anxiety, and depression) show stark sex differences in symptom patterns, age of onset, and comorbid or co-occurring conditions. One such co-occurring personality trait is neuroticism, characterized by negative affect, anger, irritability, and emotional instability. Dr. Frank Wendt and colleagues recently identified sex-specific factors influencing neuroticism including potential biomarkers relevant for disorder status (Sex-specific genetic and transcriptomic liability to neuroticism - ScienceDirect). These findings contribute novel hypotheses for understanding the role of biological sex in the presentation, etiology, and relative risk of psychiatric disorders with neurotic symptoms. (Posted August 19, 2022)


Dr. Lauren Schroeder and colleagues recently published a paper in Scientific Reports entitled “Skull variation in Afro-Eurasian monkeys results from both adaptive and non-adaptive evolutionary processes”.

Dr. Frank Wendt and colleagues recently published a large genetic study of opioid use disorder in the journal Molecular Psychiatry.

Dr. Larsen published a co-authored article in the The Lancet Psychiatry, entitled, "More phenomenology in psychiatry? Applied ontology as a method towards integration". In this piece, the authors outline a novel method on how to capture data about "first-person experiences" in mental health research. The challenge of including data about first-person experiences in research efforts is a long-standing issue that has yet to be sufficiently resolved, but also a challenge that, if mitigated, has the potential to propel research innovation and expand our knowledge about mental health diagnostics, causation, treatment, etc. (Posted July 15, 2022)

lipid vesicles

Dr. Esteban Parra and his colleagues from Mexico are co-authors of a very large study of the genetics of blood lipid levels including hundreds of scientists throughout the world. The results of this study have been published in the prestigious journal Nature. The sample included approximately 1.65 million individuals, including 350,000 of non-European ancestries. The study identified many novel genetic variants influencing blood lipid levels (LDL-cholesterol, HDL-cholesterol, triglycerides, total cholesterol, and non-HDL-cholesterol). Importantly, the study highlights the importance of including diverse populations in Genome-Wide Association Studies (GWAS). The authors of the study reported that increasing diversity resulted in improvement of fine-mapping efforts to identify putative functional variants, and the transferability of lipid concentration predictions using Polygenic Risk Scores (PRS) to multiple population groups. (Posted January 18, 2022)
