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.

Cancer is a disease that touches everyone's life at some point. It is estimated that one out of two men and one out of three women get the disease. Learn more about the statistics here.  As a learner, it's important to grasp the basic question “What is Cancer?” since it affects so many people. At the heart of cancer is a cell function issue: uncontrolled cellular division. This, in turn, creates malignant cells. Throughout this lesson you will be challenged to visualize the connection between normal cells and cancer cells. You will explore the creation of tumors. In addition, this concept will help you better understand those people around you whose lives are impacted by cancer.  StandardsBIO.B.1.1 Describe the three stages of the cell cycle: interphase, nuclear division, cytokinesis

Mechanical forces play a decisive role during development of tissues and organs, during remodeling following injury as well as in normal function. A stress field influences cell function primarily through deformation of the extracellular matrix to which cells are attached. Deformed cells express different biosynthetic activity relative to undeformed cells. The unit cell process paradigm combined with topics in connective tissue mechanics form the basis for discussions of several topics from cell biology, physiology, and medicine.

In this lesson, students use the app, Powers of Minus Ten Bone, to discover the innerworkings of cells and their organelles. Exploration of the app is guided with the use of a scaffolded worksheet as well as a class discussion. Later in the lesson, student groups are assigned a specific organelle and use the information contained in the app to draw similarities and differences between the buildings in a city to the organelles inside a cell. Students will construct a clay model of an organelle as well as a model of a city building. Finally, student groups are asked to present their work via a class presentation followed by a creative writing assignment.

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:

"The trafficking of proteins into and out of the nucleus is central to cell function In fruit flies, the process also seems to determine the fate of neural stem cells in the larval central brain Neural stem cells are essential to neurogenesis, a two-step process in Drosophila The cells first form during embryogenesis At the end of neurogenesis, the cells divide terminally and exit the cell cycle, producing new neurons A build up of the protein Prospero in the nucleus initiates this exit But what causes this accumulation? Researchers report that Prospero uses RanGAP to shuttle across the nuclear envelope Eliminating RanGAP function doesn’t affect the nuclear import of Prospero, but rather its export out of the nucleus This suggests a drop in RanGAP levels could entrap Prospero in the nucleus, hinting that an intrinsic mechanism determines the fate of neural stem cells in Drosophila and perhaps other organisms as well Wu, D., et al..."
