Discover the secret behind Gram-negative bacteria's armor-like outer membrane! A new study led by Professor Colin Kleanthous at the University of Oxford sheds light on how bacteria like E. coli construct their outer membrane to resemble body armor, with implications for developing antibiotics.
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. It's an example of how exploring academic topics through reading, reflection, and writing can inspire you to learn more about the world around you.
Stanford University researchers, in collaboration with other institutions, have developed a molecule that prevents the spike protein of the SARS-CoV-2 virus from twisting and infecting cells, including those with new variants. This new type of antiviral therapeutic, called the longHR2\_42 inhibitor, may be delivered via inhaler to treat early infections and prevent severe illness. The team's detailed understanding of the twisted structure of the virus's spike protein allowed them to create a longer molecule that is more effective than previous attempts to block the virus. Their groundbreaking research may lead to a promising solution to combat COVID-19.

The human body is made up of trillions of cells, with each cell originating deep within our bones. The porous nature of bones allows for large and small blood vessels to enter, with the hollow core of most bones containing soft bone marrow. This marrow is essential, containing blood stem cells that constantly divide and differentiate into red and white blood cells and platelets, sending billions of new blood cells into circulation every day. Blood cancers often begin with genetic mutations in these stem cells, which can result in malignant blood cells. For patients with advanced blood cancers, the best chance for a cure is often an allogeneic bone marrow transplant. This procedure involves extracting blood stem cells from a donor and infusing them into the patient's body, leading to the regeneration of healthy blood cells. While bone marrow transplants come with risks, including graft-versus-host disease, it is crucial to find the best match possible for the recipient. Donor registries offer hope to those without a matched family member. Learning about the importance of bone marrow and stem cells can inspire students to explore the fascinating world of human biology and potentially make a difference in someone's life through donation.

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.

Understanding the blueprint of life is essential to understanding how our bodies work. DNA, genes, and chromosomes are the building blocks that make up this blueprint. DNA is the most basic level and is made up of nucleotides arranged along a sugar backbone. Genes are long snippets of DNA that contain information about building proteins and are the most basic units of inheritance. Chromosomes are long strands of DNA wrapped around proteins called Histones and contain many genes. The body uses acetylation to control the production of proteins. Understanding these concepts can help you understand how traits are passed down and how the body makes an estimated one million proteins from only twenty thousand genes. Knowing the blueprint of life will help you understand how your body works and give you a foundation for further scientific exploration.

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.
