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:
"Pain is useful. It’s a natural mechanism for protecting the body in humans and other animals. However, pain that is chronic and persists longer than it should is considered a disease. Research has revealed that pain is often the result of an important interplay between the immune system and the nervous system. When the body produces an inflammatory response to injury, or disease, inflammation can activate [pain circuits], sensitize them, and lead to increased and ongoing pain. Now, using nanosized particles of medicine that momentarily switch inflammation off, researchers have discovered new clues as to how chronic pain unfolds and how it might be relieved. The team began by inducing immune-based chronic pain in rats. They did so surgically by constricting the right sciatic nerve with loosely tied sutures, causing swelling and inflammation through the infiltration of white blood cells, immune cells including monocytes that become macrophages..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.
