Stanford researchers have developed a smart bandage that painlessly falls away from the skin and tracks signs of recovery and infection. It even responds with electrical stimulation to hasten healing. The bandage resulted in 25% faster healing, greater blood flow to injured tissue, and less scarring in animal studies. The bandage is just one example of how Stanford researchers combine organic chemistry and novel materials to reimagine medical devices in more powerful, personal, and unobtrusive ways.

Have you ever had a moment of inspiration that led to a groundbreaking invention? In 1816, a doctor named René Laennec had just that moment while walking through Paris. He observed children using a long piece of wood to amplify sound and later used this concept to create the stethoscope. By placing a rolled-up sheet of paper to a young woman's chest, he was able to hear her heartbeat with clarity. Laennec spent three years perfecting his invention, which eventually became the forerunner to the stethoscopes we still use today. Learning about the development of the stethoscope not only expands your knowledge of medical history but also inspires you to think creatively and use everyday observations to solve complex problems.

Did you know that spending just a few weeks in space can lead to a 20% loss of muscle mass? That's because in microgravity, astronauts don't need to use their muscles as much to stay upright or move around. This lack of exercise leads to a breakdown in muscle tissue and a loss of strength. But it's not just astronauts who are affected by muscle degradation. People on bed rest, those with certain medical conditions, and even the elderly can experience a loss of muscle mass and function. So what's happening on a cellular level? When muscles aren't used, they begin to break down proteins for energy. This process, called protein degradation, can lead to the loss of muscle mass and function. But don't worry, researchers are working hard to find ways to combat muscle degradation in space and on Earth. One approach is to use exercise machines that simulate gravity, which have been shown to maintain muscle mass in astronauts. Other research has focused on using drugs to block the protein degradation process and promote muscle growth. Leading academics in the field of muscle degradation include Dr. Robert Fitts, a professor of biology at Marquette University, who has researched the effects of microgravity on muscle mass and function. Dr. Lori Ploutz-Snyder, a professor at the University of Michigan, has also studied muscle atrophy and is working on developing exercise programs to prevent it. Overall, muscle degradation is a serious concern for both astronauts and people on Earth. By learning more about the causes and potential solutions, we can work towards maintaining healthy muscles and preventing muscle loss.

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.
