Students are introduced to biofuels, biological engineers, algae and how they grow (photosynthesis), and what parts of algae can be used for biofuel (biomass from oils, starches, cell wall sugars). Through this lesson, plants—and specifically algae—are presented as an energy solution. Students learn that breaking apart algal cell walls enables access to oil, starch, and cell wall sugars for biofuel production. Students compare/contrast biofuels and fossil fuels. They learn about the field of biological engineering, including what biological engineers do. A 20-slide PowerPoint® presentation is provided that supports students taking notes in the Cornell format. Short pre- and post-quizzes are provided. This lesson prepares students to conduct the associated activity in which they make and then eat edible algal cell models.

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:
"A new algorithm has successfully mapped part of the brain’s circuitry during shock therapy. For those suffering from severe depression, the approach could make for safer and more effective treatment. For brain research at large, it could lead to better ways of untangling noisy neural data to reveal real connections between different focal regions of the brain. Despite the gruesome picture painted by pop culture, modern shock therapy is a mild treatment option. In fact, over 2 million treatments are administered worldwide every year. Under general anesthesia, patients receive a small amount of current to the brain, triggering a brief seizure. The resulting changes in brain chemistry have been shown to reverse symptoms of mental health conditions like severe depression or bipolar disorder. But the procedure isn’t perfect. One of the most troubling side effects is memory loss, a result of poor targeting. To be effective and safe, induced seizures should be restricted to the pre-frontal cortex..."

This course is offered to undergraduates and addresses several algorithmic challenges in computational biology. The principles of algorithmic design for biological datasets are studied and existing algorithms analyzed for application to real datasets. Topics covered include: biological sequence analysis, gene identification, regulatory motif discovery, genome assembly, genome duplication and rearrangements, evolutionary theory, clustering algorithms, and scale-free networks.

The horse is a monogastric hindgut fermenter. The horse evolved for grazing and it does so for up to 17 hours a day. A high proportion of the horse's dietary carbohydrate is in the form of starch. A mature horse eats 2-2.5% of it's body weight in dry matter every day, 1.5-1.75% of this should be fibre (hay/haylage). This is to prevent a rapid drop in pH in the large intestine and also to stimulate peristalsis in the gut and prevent build up of gas.

"Individuals with metabolic syndrome have a 2-fold increased risk of cardiovascular disease, but few strategies provide adequate cardiovascular risk reduction for this group. One option to lower this risk is to reduce atherogenic lipids, particularly low-density lipoprotein cholesterol. Statins are a recommended first-line therapy for this purpose, but this approach doesn’t always provide sufficient LDL-C lowering to optimally reduce cardiovascular risk. Now, researchers have shown that alirocumab, a proprotein converstase subtilisin/kexin type 9 inhibitor, or PCSK9 inhibitor, approved for LDL-C reduction, may address this need. Pooled clinical trial data from ten phase 3 clinical trials from the ODYSSEY clinical development program showed alirocumab significantly lowered LDL-C in individuals both with and without metabolic syndrome..."

"Alirocumab, a drug that inhibits PCSK9 and helps clear the blood of atherogenic lipids, may be of benefit for individuals with type 2 diabetes who are most at risk of cardiovascular disease. According to the International Diabetes Federation, heart disease is the leading cause of death among people with type 2 diabetes. One factor that might contribute to that grim statistic is the high mixed dyslipidemia prevalence in this population. Mixed dyslipidemia is characterized by elevated triglycerides, and hence high triglyceride-rich lipoprotein, or remnant cholesterol, and high cholesterol levels; and low serum levels of high-density lipoprotein cholesterol, or HDL-C. Despite treatment with statins and other lipid-lowering therapies targeting atherogenic lipoproteins, management of mixed dyslipidemia remains challenging, especially among individuals with diabetes..."

"Normally, an animal gets half its DNA from its mother and half from its father. But Dolly had three mothers: one mother gave Dolly her DNA; one supplied an egg; and the third, her surrogate mother, gave birth to her. Dolly is an identical twin of the mother who gave her her DNA. But Dolly is six years younger."This kid-friendly Web page helps kids understand how and why Dolly was cloned, and understand the potential benefits of cloning as well as the controversy it raises.

Commercial fishing nets often trap "unprofitable" animals in the process of catching target species. In this activity, students experience the difficulty that fishermen experience while trying to isolate a target species when a variety of sea animals are found in the area of interest. Then the class discusses the large magnitude of this problem. Students practice data acquisition and analysis skills by collecting data and processing it to deduce trends on target species distribution. They conclude by discussing how bycatch impacts their lives and whether or not it is an important environmental issue that needs attention. As an extension, students use their creativity and innovative skills to design nets or other methods, theoretically and/or through hands-on prototyping, that fisherman could use to help avoid bycatch.

Bycatch, the unintended capture of animals in commercial fishing gear, is a hot topic in marine conservation today. The surprisingly high level of bycatch about 25% of the entire global catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. They become familiar with current attempts to reduce the fishing mortality of these animals. Through the associated activities, the challenges faced today are reinforced and students are stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of bycatch.
