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.
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.

With the rise of antibiotic-resistant infections, pharmaceutical companies are giving phages a second look. In fact, a recent clinical trial showed that they work against antibiotic-resistant ear infections. Researchers are also using them to treat infected wounds in veterans and diabetics and to stop the spread of antibiotic-resistant infections. So, if you're interested in learning more about how these tiny viruses can help us fight disease, read on!
Did you know that bioreactor technology is revolutionizing the way we grow nutritious plants? Bioreactors are closed systems that use microorganisms, plant cells, or animal cells to produce a wide range of products, including food, drugs, and biofuels. With bioreactors, we can grow plants in a controlled environment, without the use of pesticides or fertilizers, and harvest them year-round. One of the most exciting applications of bioreactor technology is the cultivation of superfoods. These are foods that are nutrient-dense and have a host of health benefits, such as kale, spinach, and broccoli. By growing these plants in bioreactors, we can increase their nutritional content and make them more widely available. One example of this is how researchers at Flinders University's Centre for Marine Bioproducts Development are using bioreactors to cultivate marine microalgae, which can be turned via advanced cultivation strategies into various proteins. Cultivating microalgae is more eco-friendly than rearing animals, and may be a way to reduce the need for meat proteins, thus helping to save the environment. Another example is the use of plant cell cultures in bioreactors to produce plant-based meat alternatives. Mark Post, a pharmacologist and professor at Maastricht University in the Netherlands, has developed a process for growing "cultured meat", where animal cells are cultivated in vitro. This technology could revolutionize the meat industry, reducing the environmental impact of animal agriculture and improving animal welfare. But bioreactor technology isn't just for growing food. It's also being used to produce drugs, such as insulin, and to clean up pollution. In fact, another crucial form of bioreactor technology is bioremediation, which is the use of microorganisms to break down environmental contaminants. The future of bioreactor technology is exciting! Aside from its current uses, ongoing research probes at the possibility of bioreactors being used in cell therapy - growing healthy cells to replace diseased or damaged ones in patients. The possibilities are vast, so let's go ahead and dive into the exciting world of bioreactor technology!

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.

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.
The immune system is a crucial part of our body's interconnected system, and a healthy gut microbiome is critical to a healthy immune system. Rather than trying to boost our immune system, we should focus on supporting it through a healthy lifestyle, including regular exercise, a diverse diet with plenty of fiber and polyphenols, stress reduction, and good sleep. While there is no magic pill to boost our immune response, scientists are constantly developing new drug treatments and therapies to combat a wide range of diseases. It is also important to note that risky procedures such as faecal transplants should only be done within the confines of a medical clinic. By understanding how our immune system works, we can take steps to keep it healthy and help win the war against infection.

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!
