Genetically Engineering Our Future

Scientists today use biotechnology to insert and remove genes, altering characteristics in various organisms. This process of “genetic engineering” involves manipulating an organism’s genome—the collection of genetic material, including DNA and RNA. Interestingly, these techniques utilize  naturally occurring organisms and phenomena. Many organisms possess DNA editing tools, such as nuclease enzymes, that regulate DNA reproduction. … Continue reading

Breaking Down a Binary: New Research Suggests a Spectrum of Biological Sexes

By: Tiago Palmisano Edited by: Josephine McGowan  The discussion of gender identity has seen a sharp increase in recent years. As social stigma fades and scientific understanding increases, those who do not identify with the traditional gender binary are gaining the acceptance that all humans deserve. But the concept of “biological” sex identification remains a … Continue reading

Escaping the Vortex: Genetic Rescue as Means of Conservation

By Alexandra DeCandia Humans have a talent for disrupting natural processes. Through the overharvest of species and inundation of landscapes with highways and suburbs, we’ve continuously rendered wild populations small and fragmented. Compared to larger, outbred populations, these communities exhibit higher rates of inbreeding. If their circumstances do not improve, inbreeding depression, or reduced reproductive … Continue reading
