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.

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.

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.
