Voles Don’t Need Oxytocin to Bond
Scientists thought the “love hormone” oxytocin was required to help animals form social bonds. In this Guide, students will learn how a study using a gene-editing tool called CRISPR is questioning that perspective — at least for prairie voles.
Students will learn how CRISPR gene-editing technology works and discuss its applications and its importance to research. Learning Outcomes: Learning about CRISPR and why it is an important technology
Prairie voles can couple up even without the ‘love hormone
Students will answer questions about the online Science News article “Prairie voles can find partners just fine without the ‘love hormone’ oxytocin,” which explores how scientists upended a common understanding of the hormone by using CRISPR technology. A version of the article “Voles don’t need oxytocin to bond” appears in the February 25, 2023 issue of Science News.
The Black Death’s genetic legacy
Students will read and answer questions about the online Science News article “Black Death immunity came at a cost to modern-day health.” A version of the article, “Plague immunity left a lasting mark,” appears in the November 19, 2022 issue of Science News.
Let population genetics be your guide to evolution
Population genetics bridges the basic concepts of genes and inheritance, often studied at the individual level, with the larger concept of how a species evolves. In this discussion, students will review basic genetics concepts and investigate an example of evolution within the human population.
Old dog, new math
Students will answer questions about the online Science News article “Calculating a dog’s age in human years is harder than you think,” which explores how scientists used molecular biology to more accurately compare canine aging with human aging. A version of the story, “Calculating a dog’s age requires a bit more math,” can be found in the August 15, 2020 issue of Science News.
Cats and Punnett squares
Scientists would like to breed cats that don’t trigger allergies in people. By constructing and analyzing a Punnett square for two low-allergen cats, students will review key concepts including patterns and probabilities of inheritance, genotype, phenotype, genes, alleles, chromosomes and mutations.
How to Lick Cat Allergies
This guide asks students to explore how scientists are combating cat allergies, apply problem-solving strategies to an allergen of their choice, review basic concepts in genetics and analyze Punnett squares.
The quest to fend off cat allergies
Students will answer questions about the Science News article “How to lick cat allergies,” which explores some potential solutions to prevent and calm allergic reactions.
Taking charge of allergies
Students will identify and categorize various approaches to fending off cat allergies. After discussing the approaches, students will apply similar problem-solving strategies to a new allergen.
Ban on Gene-edited Babies Proposed
This guide explores basic topics related to gene editing and other applications of genetic engineering.
Explore genetic engineering’s legacy
These discussion prompts explore how genetic engineering has been used in medicine, agriculture and basic research.
