Students learn the function of the liver and how biomedical engineers can use liver regeneration to help people. Students test the effects of toxic chemicals on a beef liver by adding hydrogen peroxide to various liver and salt solutions. They observe, record and graph their results.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Plants frequently produce toxic chemicals to defend themselves against hungry insects, meaning that insects must often counteract these defenses if they want to obtain a meal. The Camellia weevil is one such insect that enlists the help of microorganisms living in its gut to neutralize toxins in the tea-oil camellia plant. Given the unique life cycle of this weevil, researchers were interested in finding out how its specialized gut microbiome is acquired. The team used genetic sequencing techniques to identify the microbes in samples taken from weevil guts, tea-oil camellia fruits, and the surrounding soil. They found that bacteria from the soil were primarily responsible for the toxin-degrading activity of the weevil gut microbiome. In particular, Acinetobacter sp. strain AS23 can migrate into the weevil gut and degrade the toxin saponin, thereby allowing the weevils to inhabit and feed on the tea-oil camellia fruits..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.
