This activity first asks the students to study the patterns of bird flight and understand that four main forces affect the flight abilities of a bird. They will study the shape, feather structure, and resulting differences in the pattern of flight. They will then look at several articles that feature newly designed planes and the birds that they are modeled after. The final component of this activity is to watch the Nature documentary, "Raptor Force" which chronicles the flight patterns of birds, how researchers study these animals, and what interests our military and aeronautical engineers about these natural adaptations. This activity serves as an extension to the biomimetics lesson. Although students will not be using this information in the design process for their desert resort, it provides interesting information pertaining to the current use of biomimetics in the field of aviation. Students may extend their design process by using this information to create a means of transportation to and from the resort if they chose to.

Students act as if they are biological engineers following the steps of the engineering design process to design and create protein models to replace the defective proteins in a child’s body. Jumping off from a basic understanding of DNA and its transcription and translation processes, students learn about the many different proteins types and what happens if protein mutations occur. Then they focus on structural, transport and defense proteins during three challenges posed by the R&D; bio-engineering hypothetical scenario. Using common classroom supplies such as paper, tape and craft sticks, student pairs design, sketch, build, test and improve their own protein models to meet specific functional requirements: to strengthen bones (collagen), to capture oxygen molecules (hemoglobin) and to capture bacteria (antibody). By designing and testing physical models to accomplish certain functional requirements, students come to understand the relationship between protein structure and function. They graph and analyze the class data, then share and compare results across all teams to determine which models were the most successful. Includes a quiz, three worksheets and a reference sheet.

This series of lectures was originally presented on January 9, 2009 at the "Particle Fundamentals Forum" hosted at BTEC on NCSU's Centennial Campus and is now available for you to see ON-DEMAND! You will learn about particles, what they are, how they are detected, forces on particles, and the types of instruments used to quantify these contaminants. Professionals with real-world experience will discuss on the mechanics of detecting particulate, the benefits and considerations of various monitoring techniques, and will also offer insight on the future trends associated with contamination and contamination control.
This 50-minute presentation, hosted by NCCCS BioNetwork covers: * Laser airborne particle counter for non-viable contaminants * Centrifugal air sampler for viable contaminants * Contact strips for viable contaminants from surfaces and people * Automated slide stain instrument for gram staining to identify viable contaminants.
Brunswick Community College's (BCC) Center for Aquaculture and Biotechnology (CAB) has implemented a Biofuels from Algae project as a joint effort between the departments of Aquaculture and Biotechnology. This entailed the design and construction of an 1800 gallon photobioreactor system during phase 1 of the project. Phase II focused on the downstream processing of oil extraction. BCC's CAB has a patent pending status on this process, which is purely mechanical, easily scalable and relatively cheap to implement. The final phase of the project (pending funding) will optimize and refine the oil extraction process, which will give us the opportunity to file a full patent, license the patent to industry or develop a trade secret with an industry partner, which will quickly move the process to commercialization. If the final phase is funded we will also obtain data on the yield of oil production, yield to biodiesel conversion, chemical composition of the extracted oil and determine the best species for use in the process developed at BCC.
Have you ever asked what “biobased” means or wondered about the key aspects in developing and commercializing biobased products? This course will answer those questions and more; highlighting the opportunities, hurdles, and driving forces of the bioeconomy.
Today’s industries face enormous global challenges when it comes to the fossil-based economy. Fossil resources are no longer a desirable feedstock for many products and governments’ climate goals put various limitations to its usage. Moreover, consumer perception has become an increasingly important factor. With biobased products as an alternative to the fossil-based economy, the bioeconomy can provide viable solutions to these challenges.
The course describes the different types of biomass, the methods of refinery and typical conversion technologies used for biobased products. You’ll also engage in a study of the practical and real-life examples emerging in the market: biopolymers, bioenergy, bioflavours, and biosurfactants.
The course has been developed by a team of experts from seven different institutions and universities in three different countries, all sharing their personal perspectives on the opportunities and challenges faced by the biobased industry. The three top-ranked institutions Delft University of Technology, RWTH Aachen University, and Wageningen University & Research offer additional, more advanced courses to continue your learning journey:
Industrial Biotechnology: a more advanced course that digs deeper into engineering aspects of bio-based products.
MicroMasters Chemistry and Technology for Sustainability: Help drive the transition from fossil sources to renewable energy ones and engineer a biobased future.
Sustainable Development: The Water-Energy-Food Nexus: Introduction to sustainable development and its relation to the Water-Energy-Food Nexus.

Paul Andersen introduces the topic of Biology. He covers each of the four main ideas that were developed by the College Board. These ideas revolve around the concepts of evolution, free energy, information and systems.
Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term. From its earliest beginnings, biology has restled with these questions: What are the shared properties that make something “alive”? And once we know something is alive, how do we find meaningful levels of organization in its structure?
