Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

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:

"Stroke is the leading cause of death worldwide. Scientists are finding that mitochondrial abnormalities play a central role in stroke. A recent study suggests that deactivating the protein SIAH2 could help mitochondria and the brain cells they power survive stroke in mice. Oxygen deprivation, which makes stroke fatal, activates SIAH2. Once activated, SIAH2 signals the breakdown of mitochondrial and cellular proteins key to survival. Aiming to curb this damage, researchers switched off the gene controlling SIAH2 formation in mouse neurons. and observed what happened after artificially inducing stroke. They found that without SIAH2, neurons suffered low damage during stroke. preserving the machinery that keeps mitochondria alive and well. Understanding how this switch operates in humans is crucial. as it could lead to drugs that target SIAH2 and help reduce the mortality of stroke..."

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

This unit delves into the fundamental science and historical contexts to help students explore the question "How can knowledge gained from the Manhattan Project and the Hanford Site contribute using nuclear technologies to positively impact humanity in the future?."Nuclear Chemistry is a great capstone unit for a standard high school chemistry course in that it is fantastic opportunity for students to explore the crossroads between scientific knowledge and the societal implications of new discoveries. Students will have the opportunity to Delve deep into the science standards while also connecting their learning to what it means for us as a global society.
