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.
By the end of this section, you will be able to:List the steps of replication and explain what occurs at each stepDescribe the lytic and lysogenic cycles of virus replicationExplain the transmission and diseases of animal and plant virusesDiscuss the economic impact of animal and plant viruses
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:
"Of the twelve cranial nerves that pass through the skull, the facial nerve is most susceptible to traumatic injury and paralysis. One technique for repairing such damage is polyethylene glycol-mediated cell fusion – or PEG-fusion – but this hasn’t been tested on facial nerves. Moreover, when looking at other nerve types, it’s only been applied immediately after injury. This doesn’t reflect real-world clinical practice, where nerve damage may not be addressed for days as life-saving interventions are prioritized. Now, researchers have applied PEG-fusion to facial nerves using a more clinically relevant timeline, and the results suggest that nerve regeneration is possible even when treatment is delayed. PEG-fusion helps restore the protective boundary of a nerve cell’s plasma membrane by plugging the holes caused by traumatic injury, which can seal the cell off from potentially toxic substances. But it hasn’t been clear whether delayed treatment can still help cells heal..."

As part of this activity, students learn about geologic processes on Earth in order to interpret surface features recently seen on Europa by NASA's Galileo spacecraft. Materials presented here include a vocabulary list, geology jigsaw puzzle, review questions, and links to related sites.
Just after World War II, nuclear scientists turned their attention from fission to fusion. This video segment adapted from AMERICAN EXPERIENCE looks at the beginnings of thermonuclear power generation.
This laboratory manual is an introduction to a standard chemical lab course for Arizona Community Colleges CHEM 130. It covers basic protocols, glassware, and handling techniques. Students will be presented with full immersive experiences to enrich their understanding of basic chemistry.
Nuclear energy is a carbon-free and extremely energy dense resource that produces no air pollution. Nuclear reactions produce large amounts of energy in the form of heat. That heat can be used to power a steam turbine and generate electricity. There are 2 types of nuclear energy: nuclear fission (which is used today to produce electricity) and nuclear fusion (which is still in the research phase).
This is an introductory graduate-level course on the phenomenology and experimental foundations of nuclear and particle physics, including the fundamental forces and particles, as well as composites. Emphasis is on the experimental establishment of the leading models, and the theoretical tools and experimental apparatus used to establish them.

"Stroke is the leading cause of death worldwide. Scientists are finding that mitochondrial abnormalities play a central role in stroke. A recent study suggests that deactivating the protein SIAH2 could help mitochondria and the brain cells they power survive stroke in mice. Oxygen deprivation, which makes stroke fatal, activates SIAH2. Once activated, SIAH2 signals the breakdown of mitochondrial and cellular proteins key to survival. Aiming to curb this damage, researchers switched off the gene controlling SIAH2 formation in mouse neurons. and observed what happened after artificially inducing stroke. They found that without SIAH2, neurons suffered low damage during stroke. preserving the machinery that keeps mitochondria alive and well. Understanding how this switch operates in humans is crucial. as it could lead to drugs that target SIAH2 and help reduce the mortality of stroke..."

This unit delves into the fundamental science and historical contexts to help students explore the question "How can knowledge gained from the Manhattan Project and the Hanford Site contribute using nuclear technologies to positively impact humanity in the future?."Nuclear Chemistry is a great capstone unit for a standard high school chemistry course in that it is fantastic opportunity for students to explore the crossroads between scientific knowledge and the societal implications of new discoveries. Students will have the opportunity to Delve deep into the science standards while also connecting their learning to what it means for us as a global society.
Nuclear fusion has the potential to be an extremely energy dense and carbon-free energy resource that does not produce air pollution or radioactive waste. However, while nuclear fusion happens continuously in (and even powers) the sun, making nuclear fusion happen on earth is extremely challenging (think about putting the sun in a box). Currently, fusion is in the research phase and is not commercially viable. Nuclear fusion occurs when nuclei from two or more atoms are forced together and fuse to form a single larger nucleus, releasing lots of energy and heat. That heat would then be used to generate electricity.
These concept connection cards can be used in small groups or for self study. They help students build an understanding of three core topics in astronomy -- the HR diagram, light, and fusion. The file includes instructions for usage, as well as cards in multiple formats. They were created by Kaisa Young from Nicholls State University.
