Learning about the chemistry of onions may not seem like the most exciting academic topic, but it can help you understand how things work in the world around you. When you chop an onion, you're changing its chemistry and releasing a gas that causes your eyes to water. You can slow down the onion's enzymes by storing it in the fridge or boiling it briefly, or you can wear goggles or sunglasses while cutting it. Scientists are even working on creating tear-free onions through genetic modification and traditional plant breeding. Learning about the chemistry of onions can help you appreciate the complexities of the natural world and give you practical skills for your everyday life.
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.

The world of science is constantly evolving, and with it comes new discoveries that can benefit humanity. However, there are also risks associated with scientific research, particularly in the field of biotechnology. Gain of function work involves manipulating the DNA of microorganisms to give them new abilities, which can be used in vaccine production and cancer treatments. However, this work also includes engineering superbugs that could cause a global pandemic if they escape from the lab. While virologists argue that this research could help us prepare for future pandemics, critics believe that the risks outweigh the benefits. To minimize the risk of lab leaks, experts suggest creating international databases of leaks, near-misses, and fixes, as well as developing a robust pandemic early warning system. As students, it is important to understand the benefits and risks of scientific research and to be aware of the measures being taken to minimize the risks associated with it.
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.
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.

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 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.

DNA is a molecule that holds the secrets of life within its code, and it's waiting for you to explore it! This amazing molecule determines our traits, from our physical appearance to our personalities, and it can also tell us about our ancestry, our risk of diseases, and much more. Leading academics in the field of genetics, such as James Watson and Francis Crick, made major contributions to our understanding of DNA by discovering its structure and how it stores and transfers genetic information. Watson and Crick's discovery of the double helix structure of DNA was a major turning point in the field of genetics and opened up new avenues for scientific research. In the early 1990s, the Human Genome Project was launched to map all of the genes in human DNA. This project was a huge success and has had a profound impact on the field of genetics. It allowed scientists to identify specific genes that are associated with different diseases, such as cancer, and has paved the way for new treatments and cures. One of the most fascinating things about DNA is that every person's DNA is 99.9% identical to every other person's DNA. It's the remaining 0.1% that makes each of us unique! Our DNA also contains fascinating stories about our ancestors and their migrations. For example, DNA testing can tell us where our ancestors came from and how they migrated across the world. This is known as genetic genealogy, and it's an exciting field that combines genetics and history. Another fascinating aspect of DNA is its role in evolution. Charles Darwin's theory of evolution by natural selection states that species change over time through the process of natural selection. This process occurs because certain traits that provide an advantage in survival and reproduction become more common in a population over time. DNA mutations can lead to changes in traits, and over many generations, these changes can accumulate and result in new species. By exploring the world of DNA, you will not only deepen your understanding of genetics and biology, but also gain a new appreciation for the complexities and wonders of life. So go ahead, unlock the secrets of life with the power of DNA!
