Do you ever wonder why orange juice tastes so bad after brushing your teeth? It turns out that our taste buds, which are made up of taste receptor cells, are responsible for identifying different tastes like sweet, bitter, and savory. Toothpaste contains Sodium Lauryl Sulphate (SLS), which creates foam while brushing and temporarily gets rid of the molecules that block our bitter receptors. This makes the receptor much more sensitive to bitter flavors, causing that awful taste. However, taste isn't just affected by our receptors. Temperature, texture, and smell can change what we sense too. Learning about the science of taste can help you understand why some foods taste the way they do and how to enhance your dining experience. So, next time you have OJ after brushing, try plugging your nose or go for a coffee or Bloody Mary instead.

Sugar is a staple in the modern diet, but it can also be a health hazard when consumed in excess. As a result, sugar substitutes have become increasingly popular in recent years. In this write-up, we will explore the science and effectiveness of sugar substitutes, including the various types of sugar substitutes and their effects on the human body. One of the most widely used sugar substitutes is aspartame, which is commonly found in diet soda and other low-calorie products. While aspartame has been the subject of much debate, studies have shown that it is safe for human consumption in moderate amounts. Another popular sugar substitute is stevia, which is derived from a plant and has no calories. Stevia has been shown to be an effective sugar substitute for people with diabetes, as it does not raise blood sugar levels. But not all sugar substitutes are created equal. For example, sugar alcohols like xylitol and erythritol can cause digestive issues when consumed in large quantities. And some artificial sweeteners like saccharin have been linked to an increased risk of cancer. Leading academics in the field of sugar substitutes include Dr. Marion Nestle, a professor of nutrition at New York University, and Dr. Richard Mattes, a professor of nutrition science at Purdue University. These experts have conducted extensive research on the effects of sugar substitutes on the human body and can provide valuable insights into the topic. The science and effectiveness of sugar substitutes are fascinating topics that can inspire students to explore the world of nutrition and health. By encouraging independent exploration and self-directed projects, we can empower high school students to take ownership of their learning and develop a lifelong love of academic inquiry.

Have you ever wondered why we crave certain foods more than others? It turns out that our brain's reward system is responsible for this. The orbital frontal cortex, a part of the brain that responds to different sensations and nutrients, is especially developed in humans and primates. This part of the brain is responsible for our cravings and delights in fat and sugar. However, having information about the food can make a big difference. We can use our knowledge of what is happening in our brains to design foods that are low in calories and still attractive, but healthy. Understanding how our reward neurons plot to get what they want can help us be aware of times that we tend to make poor choices. In the end, we are not fully at the mercy of our reward neurons. We can use our understanding to help design healthy foods and make healthy choices. By learning more about the science behind our food choices, we can make better decisions for our health and wellbeing.

Chemotherapy is a type of cancer treatment that uses drugs to kill rapidly dividing cancer cells in the body. The drugs are delivered through pills and injections and are toxic to all cells in the body, including healthy ones. However, cancer cells are more susceptible to the effects of chemotherapy because they multiply rapidly. Chemotherapy drugs can damage hair follicles, cells of the mouth, gastrointestinal lining, reproductive system, and bone marrow, which can cause side effects such as hair loss, fatigue, infertility, nausea, and vomiting. Despite these side effects, chemotherapy has greatly improved the outlook for many cancer patients. Advances in treatment have led to up to 95% survival rates for testicular cancer and 60% remission rates for acute myeloid leukemia. Researchers are still developing more precise interventions to target cancer cells while minimizing harm to healthy tissues. Learning about chemotherapy can help high school students understand the science behind cancer treatment and the importance of ongoing research to improve outcomes for patients.

Food is energy for the body, and the average number of calories in fat, protein, and carbohydrates is still used as an important marker for nutrition today. However, biologist Rob Dunn explains that there is no such thing as an average food or person. How many calories we extract from food depends on the biology of the species we are eating, how we cook and process our food, and even on the different bacterial communities in different people's guts. Standard calorie counts don't take any of these factors into consideration, resulting in numbers that are slightly inaccurate, at best, and sometimes rather misleading. Digestion turns out to be such a messy affair that we'll probably never have precise calorie counts for all the different foods we'd like to eat and prepare in so many different ways. However, learning about the biology of food and digestion can help us make better choices and understand our bodies better.

Learning about the science of breath-holding can be a fascinating and beneficial academic pursuit for high school students.
