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:

"Human immunodeficiency virus (HIV) and the malaria-causing parasite Plasmodium infect millions of people around the globe. These two diseases have broad overlap in their endemic regions, and in some areas over a quarter of HIV patients also have malaria. But despite how common coinfection is, researchers know little about how coinfection and order of infection impact patients. So, a team of scientists turned to a Chinese rhesus macaque research model. In this model, instead of HIV, the macaques had the related virus simian immunodeficiency virus (SIV). The scientists found that animals infected with the malaria parasite before SIV produced more of the immune cells that SIV uses to replicate, increasing the viral load and accelerating disease progression. But when the infection order was reversed, a subsequent malaria infection activated virus-specific T cells against SIV. ultimately improving survival in those animals..."

This health education program discusses malaria including the causes, symptoms, diagnosis, and treatment. It also provides prevention tips for those traveling to countries where malaria is common. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

"In cancer, tumor cells secrete chemicals that suppress immune function by upregulating the expression of immune “brakes”. Immunotherapy with checkpoint inhibitors can release these brakes to effectively treat certain types of cancer. However, other types of cancer are resistant to checkpoint inhibitors, so alternate treatments are needed. In mouse models, infection with the malaria parasite Plasmodium can activate immune defense against cancer. Similarly, global human epidemiological data indicate that malaria occurrence is inversely associated with cancer mortality. In mice, Plasmodium induces proinflammatory molecule production, immune cell activation, and subsequent systemic immune responses while simultaneously upregulating the expression of brake molecules through a feedback mechanism of the immune system to prevent unchecked damage by these immune responses..."

"Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Treatments for HCC are limited, and the survival rate remains low. Now, a new study suggests a novel treatment that relies on a unique method of preventing tumor growth. The study focuses on Plasmodium, the parasite that causes malaria. Interestingly, infection with Plasmodium can boost immune cell function, and Plasmodium infection is known to have an antitumor effect. Researchers used a mouse model of HCC to examine the effect of Plasmodium infection on HCC progression. Their results showed that Plasmodium infection efficiently inhibited tumor progression and prolonged survival. Plasmodium infection suppressed tumor angiogenesis, cutting off the tumor’s blood supply. Plasmodium infection also reduces the number of tumor-associated macrophages through malarial pigment. These macrophages help to build blood vessels within tumors..."
