Discover the scientist who uncovered the savory fifth taste, umami, and how it's related to the infamous MSG. Learn how umami has become a buzzword in the culinary world, inspiring chefs to create meaty flavors in meatless dishes.

Have you ever wondered why some foods taste savory, rich, and satisfying? Well, the answer lies in the fifth taste sensation: Umami. The discovery of Umami, which means "pleasant savory taste" in Japanese, revolutionized the world of cooking and seasoning. Umami was first identified by the Japanese chemist Kikunae Ikeda in 1908. He identified the presence of glutamates in seaweed broth as the source of its savory flavor. Since then, the role of Umami in cooking has been widely recognized, and it has become a crucial ingredient in many dishes worldwide. Umami acts as a flavor enhancer, balancing the taste of sweet, sour, bitter, and salty in food. It's the secret behind the deliciousness of dishes like tomato sauce, Parmesan cheese, and soy sauce. Not only does it enhance the taste of food, but it also makes it more satisfying and filling, making it a crucial component of healthy and balanced meals. Leading academics in the field, such as George Charalambous and Gary Beauchamp, have conducted extensive research on the science of umami and its effects on the human palate. They have found that the combination of umami with other tastes can create a synergistic effect, increasing the overall pleasure of the meal.

Have you ever wondered why a black eye turns blue, then green, then yellow, and finally brown before disappearing? It's all because of your hemoglobin, the compound in red blood cells that brings oxygen to your body. When you get hit, the blow crushes tiny blood vessels called capillaries, and red blood cells ooze out of the broken capillaries into the surrounding tissue. From the outside of your skin, this mass of cells looks bluish-black, which is where we get the term, "black and blue". Learning about hemoglobin and how it works in your body can be fascinating and practical knowledge that can help you understand how your body works.

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.

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.

Mitochondria are often referred to as the powerhouses of the cell and for good reason. These tiny organelles are responsible for producing the energy that our cells need to function. In this write-up, we'll explore the magic of mitochondria and why they are so important to our health and well-being. Did you know that mitochondria are sometimes referred to as the "second genome"? This is because they have their own DNA and can replicate independently of the cell's nucleus. This discovery, made by Dr. Douglas C. Wallace in the late 1970s, revolutionized our understanding of cellular biology. Another interesting fact about mitochondria is that they are thought to have originated from a symbiotic relationship between early cells and primitive bacteria. Over time, the two organisms evolved together to form the cells that make up our bodies today. This theory, known as the endosymbiotic theory, was first proposed by Dr. Lynn Margulis in the 1960s. So, what exactly do mitochondria do? Well, they are responsible for producing energy in the form of ATP (adenosine triphosphate) through a process called cellular respiration. This energy is then used by our cells to carry out all of their functions, from moving and growing, to repairing and reproducing. It's important to note that our cells can't survive without energy, and without mitochondria, we wouldn't be able to produce enough energy to support our bodies. This is why mitochondria are so critical to our health and well-being. By learning more about the magic of mitochondria, you'll gain a deeper understanding of cellular biology and the role that these tiny organelles play in our lives. So, get reading, reflecting, and exploring!

Cells are the fundamental units of life, driven by the forces of the universe, and are impossible machines. They are biological robots that follow their programming, which has evolved over billions of years. Your cells are mostly filled with water molecules and proteins, which are the dead things that make life happen. Cells speak the language of life, which is made up of proteins that are formed from amino acids. Amino acids are the alphabet of the language of life, and proteins are the words that form sentences called biological pathways. The language of life is complex, and mindless cells speak it through DNA, which contains instructions, genes, and building manuals for all the proteins your cells need to function. Understanding the language of life can help you appreciate the amazing complexity of cells and their role in keeping you alive.

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.
