Most colon cancers may be caused by infections with bacteria that are normally found in cows. For decades we have known that Streptococcus gallolyticus gallolyticus (SGG) is sometimes found in colon tumours, but now the microbes have been found to directly cause tumour growth in mice.

As you read the chapters in Stiff, attach a post-it note to pages where you highlight something interesting. You should have 4-10 Post-It's per chapter, use the following symbol guide to create your notes. Stiff has 12 chapters, you are only required to map (Post-It) 8 of those chapters. You are welcome to read them all, of course, but you can also choose to focus on chapters that interest you the most or skip those you do not find interesting. You may wish to skim the chapters or browse the table of contents. Each Post-It will contain three items 1. Symbol (see chart) 2. Page and paragraph number 3. Content

What does it mean to be 'alive'? At a basic level, viruses are proteins and genetic material that survive and replicate within their environment, inside another life form. In the absence of their host, viruses are unable to replicate and many are unable to survive for long in the extracellular environment. Therefore, if they cannot survive independently, can they be defined as being 'alive'?

Scientists are not sure whether viruses are living or non-living. In general, scientists use a list of criteria to determine if something is alive. Let's look at some traits of living things and see if viruses also have those traits.

Viruses have a huge impact on our lives, and we're making great strides into understanding how to protect ourselves from the flu and HIV. But one thing that scientists have struggled to agree on is whether or not viruses are alive.

A paper published today in Science Advances just might change that. By creating a reliable method of studying viruses' long evolutionary history-hitherto nearly impossible-researchers have found new evidence that strongly suggests viruses are indeed living entities.

5:11 video Chat with a friend about an established scientific theory, and she might reply, "Well, that's just a theory." But a conversation about an established scientific law rarely ends with "Well, that's just a law." Why is that? What is the difference between a theory and a law... and is one "better"? Matt Anticole shows why science needs both laws and theories to understand the whole picture.

"After the Rainbow" is a video safety message focusing on preventing accidents in high school chemistry laboratories

This flipped case study explores how the topics of membrane structure, transport, and signaling via membrane-bound receptors are intimately associated with the paralysis of muscle targeted by botulinum neurotoxin. The case scenario revolves around a fictitious socialite that has requested the assistance of her personal concierge physician with a condition that has developed after having participated in a Hamptons Botox party. The physician and a shadowing pre-med undergraduate chat about the molecular mechanisms behind Botox induced muscle paralysis. The case is designed as an engaging capstone exercise for students to gain appreciation for how knowledge of basic cellular and molecular biology mechanisms are essential for pharmaceutical development and medical patient diagnosis and prognosis. Written for an undergraduate general biology course, the case is also suitable for use in courses such as cellular biology, neurobiology, or human physiology.

Teacher site with solid resources, including Literacy Labs. "Literacy Lab" assignments are going to be introduced as the year progresses to assure that students are exposed to the literacy aspects of the soon to be developed and implemented Common Core Standards.

This case study explores the topics of diffusion, osmosis, membrane transport, and the physiological significance of glucose and insulin in the human body. The story begins with a high school athlete, Timmy, who is incredibly efficient at metabolizing carbohydrates for energy; this is where the reader is introduced to normal carbohydrate digestion and metabolism for energy within skeletal muscle cells. As Timmy enters college, he withdraws from sports and physical activity but continues to consume massive amounts of highly soluble carbohydrates, resulting in insulin resistance and ultimately type II diabetes. Throughout the case students are prompted with conceptual questions and interactive figures that require the application and transfer of information they have been introduced to. Originally written for intermediate and advanced physiology courses that cover foundational and complex concepts in science, the case is also appropriate for courses in intermediate biology, nutritional sciences, animal sciences, and exercise sciences.

You've always been told sugar is bad for you, but how bad is it really? Find out in this science music video - researched, written, sung, directed, shot, and edited by 8th graders from The Nueva School in California. This song is a science parody of "Sunday Candy" by Donnie Trumpet & The Social Experiment, featuring Chance the Rapper and Jamila Woods.

Scientists may debate the accuracy of this equivalency, but most people agree that humans live many times longer than their furry friends. And, as it happens, these friends have features that uniquely qualify them to help us speed biomedical research.

Brief article discussing changes in taxonomy and classification

Article objectives To identify the four new kingdoms that were added to the original Linnaean taxonomy. To describe the three domains of the three-domain system of classification. To explain why the three-domain system may need revision in the future.

Analogy of organizing music for taxonomy, then works through classification for humans.

7:41 Explores classification in biology as well as taxonomy hierarchy: domain, kingdom, phylum, class, order, family, genus, and species with The Amoeba Sisters! This video also discusses the importance of scientific names and why classification can have major changes due to DNA and cell structure evidence.

Taxonomy, the practice of classifying biodiversity, has a venerable history. Although early natural historians did not recognize that the similarities and differences among organisms were consequences of evolutionary mechanisms, they still sought a means to organize biological diversity.

Early classification systems probably grouped organisms as to whether they were beneficial or harmful. Another ancient classification system recognized 5 animal groups - domestic animals, wild animals, creeping animals, flying animals, and sea animals.

Taxonomy is the study of scientific classification, in particular the classification of living organisms according to their natural relationships. Taxonomy's first father was the philosopher Aristotle (384-322 BC), sometimes called the "father of science." It was Aristotle who first introduced the two key concepts of taxonomy as we practice it today: classification of oranisms by type and binomial definition.
