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:
"Increased blood flow to the uterus during pregnancy is essential to the health of both mother and baby But the cellular processes that promote blood flow during pregnancy aren’t fully understood Now, researchers have discovered that fat surrounding blood vessels in the uterus plays a key role In pregnant rats, uterine blood flow was up to 3 times higher than in non-pregnant rats But blood flow plummeted when fat tissue was removed from the uterus of pregnant rats Interestingly, tests on isolated vessels demonstrated that fat tissue-shrinking factors could be at play which seems counterintuitive because narrow vessels generally mean low blood flow One explanation is that isolating tissue from its natural surroundings could produce changes not observed in a live animal Future studies will explore this apparent contradiction and hopefully reveal the role of fat tissue in human pregnancy Osikoya et al..."
