Modeling CRISPR gene drives for suppression of invasive rodents using a supervised machine learning framework.

Invasive rodent populations pose a threat to biodiversity across the globe. When confronted with these invaders, native species that evolved independently are often defenseless. CRISPR gene drive systems could provide a solution to this problem by spreading transgenes among invaders that induce population collapse, and could be deployed even where traditional control methods are impractical or prohibitively expensive.

Ethical research engagement with Indigenous communities.

Introduction: Canada's colonial policies and practices have led to barriers for Indigenous older adults' access to healthcare and research. As a result, there is a need for Indigenous-led research and culturally safe practices. Morning Star Lodge is developing a training module to assist AgingTech researchers on ethical, culturally safe ways to engage Indigenous communities.

Reducing resistance allele formation in CRISPR gene drive.

CRISPR homing gene drives can convert heterozygous cells with one copy of the drive allele into homozygotes, thereby enabling super-Mendelian inheritance. Such a mechanism could be used, for example, to rapidly disseminate a genetic payload in a population, promising effective strategies for the control of vector-borne diseases. However, all CRISPR homing gene drives studied in insects thus far have produced significant quantities of resistance alleles that would limit their spread.
