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.
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!

Tardigrades have even been featured in popular culture, including an episode of Star Trek: Discovery, where they were used as a propulsion system for a spaceship. But while tardigrades may seem like science fiction, they are very much a real and fascinating part of the natural world. These tiny, water-dwelling creatures, also known as water bears or moss piglets, have been around for over half a billion years and have evolved some truly remarkable survival strategies. Tardigrades can survive in extreme environments that would kill most other organisms, including temperatures ranging from -272°C to 151°C, pressures six times greater than those at the bottom of the ocean, and even the vacuum of space. They can also survive dehydration, radiation, and exposure to toxins. Tardigrades achieve this impressive feat through a combination of strategies, including the ability to enter a state of suspended animation called cryptobiosis, which allows them to survive without water for years. One of the key factors that enable tardigrades to survive in such extreme conditions is their ability to repair their DNA. Tardigrades have a unique protein called Dsup, which protects their DNA from damage caused by radiation. This protein has even been shown to protect human cells from radiation damage. Dr. Thomas Boothby, a leading tardigrade researcher at the University of Wyoming, has discovered that tardigrades can also produce large amounts of unique proteins called tardigrade-specific intrinsically disordered proteins (TDPs) in response to desiccation. These proteins help protect the tardigrades' cells from damage and prevent them from drying out. Tardigrades are fascinating not just for their survival abilities, but also for their unique biology. They have a complex digestive system, a unique nervous system, and a fascinating reproductive system that involves the transfer of genetic material between individuals. By exploring the science behind these tiny creatures, we can gain a deeper understanding of the natural world and the amazing ways that living organisms can survive and thrive in even the most extreme conditions.
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.
