Biochemistry: Free For All
Kevin Ahern; Indira Rajagopal; Taralyn Tan · Oregon State University · 2018
We are happy to welcome you to our second Open Educational Resource (OER) textbook, Biochemistry Free For All. Biochemistry is a relatively young science, but its rate of growth has been truly impressive. The rapid pace of discoveries, which shows no sign of slowing, is reflected in the steady increase in the size of biochemistry textbooks. Growing faster than the size of biochemistry books have been the skyrocketing costs of higher education and the even faster rising costs of college textbooks. These unfortunate realities have created a situation where the costs of going to college are beyond the means of increasing numbers of students.

Entomology 311 Lab Manual
Melissa Scherr; Daniel Adams; Baylee Bullock · Oregon State University · 2019
Labs in this book supplement the information gained in lecture, as well as providing some perspective and experience with hands-on applications of ideas in pest management. The labs are presented in week-by-week order, so the pre-labs and reading for week 1 are labeled “Pre-Lab 1” and “Week 1 Reading”. Pre-Labs are assignments to be done before lab meets, and will be due at the beginning of Lab. Complete the labs using your textbook, web resources, or the reading assigned for the week. Readings are short 1-3 page “chapters” covering background topics pertinent to the upcoming lab, particular groups of insects/arthropods, or methods used in Pest Management. This should be read before coming to Lab each week. Lab Assignments need to be printed and brought to class so that they can be completed as a group in Lab. It is sometimes helpful to read through the assignment ahead of time to get an idea of the subject matter for the week.

Foundations of Epidemiology
Marit Bovbjerg · Oregon State University · 2019
This book is intended to provide a basic introduction to epidemiologic methods and epidemiologic thinking. After reading this book, you should be able to read an epidemiologic study, understand what the authors did and why, and identify what they found. You will also have the tools to assess the quality of that study—how good is the evidence? What are potential sources of bias, and how might those have affected the results? This book will not teach you enough to be able to design and conduct your own epidemiologic studies—that level of understanding requires several years of specialized training. However, being able to read and understand the scientific literature about human health will allow you to apply that understanding to your own work in a nuanced, sophisticated way.

Virology Lab Exercises for Undergraduates
Eric Ryndock · The Pennsylvania Alliance for Design of Open Textbooks (PA-ADOPT) · 2026
This laboratory manual presents a novel series of undergraduate-friendly experiments designed to provide students with a safe, accessible, and comprehensive introduction to virology. The manual is intended for students who already possess foundational knowledge in cell biology, genetics, and molecular biology, and it emphasizes hands-on learning through diverse experimental approaches. Unlike many existing virology laboratory manuals that depend on costly infrastructure such as mammalian cell culture facilities or focus narrowly on a single viral system, this manual was developed specifically for primary undergraduate teaching institutions. The experiments utilize readily available equipment while exposing students to representative viruses that infect bacteria, plants, and animals. Through these investigations, students gain practical experience with modern virological techniques and develop transferable, employable skills relevant to biotechnology, research, and related industries. Collectively, the laboratory exercises aim to strengthen conceptual understanding of viral biology, promote technical competency, and inspire student curiosity about viruses as dynamic and influential biological entities.

Investigations in Experimental Physics
Peter Polito; James Walsh; Jeff Gagnon · Peter J. Polito, James E. Walsh, and Jeff L. Gagnon · 2025
As stated in previous editions, the purpose of the physics laboratory is not only to reinforce the physical principles studied in the classroom but also to stimulate the development of skills and techniques required to carry out well-designed experimental investigations. It is the hope of the authors that the experimental skills and techniques acquired in this laboratory will be carried over by the student to their respective areas of interest. It is, in fact, strongly suggested that the student make an effort early in their undergraduate career to become familiar with the current research problems in their area of interest. The student should always be aware of the applicability of skillsand techniques developed in this laboratory to their field of study. This manual can be used in a one semester or two semester course. At our institution, we use it in a two semester General Physics course designed primarily for health science majors (Physical Therapy, Biology, Physician Assistant, etc.). It it also used in a one semester Physics for Movement Science course designed for movement science majors (Exercise Science, Athletic Training, Physical Education, etc.). The tenth edition of the manual is a major revision of the ninth edition. Nearly all of the diagrams were updated, pictures of the lab equipment were included for every lab, and more tables were added to record data for each lab. Six new labs on Vector Addition and Subtraction with Applications, Graphical Interpretation, Motion Analysis, Applications of Rotational Equilibrium, Impulse-Momentum Vertical Jump Application, and Basic Exploration of Electric Fields Due to Point Charges were added. In addition, three older labs that we no longer have equipment to perform were removed (Hygrometry, Measurement of the Speed of Sound in Air by Kundt’s Method, and Spectrometry). Many of the other labs were also updated and supplemented by adding a simulation component using the Phet online simulations. The student is requi

Bacterial Genomes
Aswin Seshasayee · Open Book Publishers · 2025
Microbes form the “unseen majority” of life on Earth, with bacteria at the forefront as both the architects of life’s chemical foundations and agents of disease. But their story is far more complex. Bacteria thrive in diverse and extreme environments, driven by the dynamic evolution of their genomes. These tiny organisms wield an extraordinary ability to adapt, balancing genetic changes across generations with rapid physiological responses to environmental shifts. In Bacterial Genomes, the evolutionary and regulatory processes that shape bacterial life are brought to life. This textbook offers a conceptual exploration of how bacterial genomes are organized, how they evolve, and how their genetic information is interpreted through intricate molecular networks. Drawing on both cutting-edge research and the historical milestones that shaped microbiology, it illuminates how bacteria navigate the intersection of genetic adaptation and ecological resilience. Designed for college students, interdisciplinary researchers, and even the determined amateur, Aswin Seshasayee moves beyond technical jargon to provide a thought-provoking synthesis of bacterial evolution and adaptation. Unlike traditional genomics texts, this book blends historical insights with contemporary discoveries, offering a fresh perspective on the role of bacteria in shaping the living world.
