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:
"In the discipline of planetary protection, spacecraft are assembled in unique cleanrooms to prevent microbe transfer between planets. The cleanliness of these rooms has traditionally been assessed with the NASA standard spore assay (NSA), but advanced molecular techniques have revealed that this assay may be insufficient for contamination control. To learn more, researchers recently analyzed floor samples collected over 6 months from the Spacecraft Assembly Facility at NASA’s Jet Propulsion Laboratory. The NSA coupled with Sanger sequencing identified 16 genera of bacteria, 97% of which were spore-formers, primarily Bacillus subtilis and Virgibacillus pantothenticus. However, 16S rRNA amplicon sequencing detected 51 additional bacterial genera. When viable and dead organisms were differentiated, amplicon sequencing identified 46 viable non-spore-forming genera (86% of bacteria) and 8 viable spore-forming genera (14% of bacteria)..."
