The discovery of antibiotics in the 20th Century revolutionized healthcare, adding an average of 20 years to everyone's life. However, the overuse and misuse of antibiotics have led to the rise of antibiotic-resistant bacteria, or superbugs, which could cause a health crisis worse than any we've experienced this century. By 2050, it's predicted that 10 million people will die every year from complications with superbugs. A world without antibiotics would be catastrophic, impacting our food chain and causing many to die younger than they do now. As students, it's important to understand the consequences of antibiotic misuse and to be cautious when taking antibiotics. By finishing the full course of antibiotics, we can prevent the development of antibiotic-resistant bacteria. Additionally, we should be aware of the need for new antibiotics and support efforts to fund research into finding them. Anticipating problems and taking action before they become global crises is key to protecting our health and future.
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.

Antibiotics are drugs used to treat bacterial infections, but over time, bacteria can develop the ability to resist these drugs, making infections much harder to treat. This problem is compounded by the overuse and misuse of antibiotics, which speeds up the development of resistance. According to the World Health Organization (WHO), antibiotic resistance is one of the biggest threats to global health today. In the United States alone, more than 2.8 million antibiotic-resistance infections occur each year, and at least 35,000 people die as a result. Dr. Ramanan Laxminarayan, director of the One Health Trust, has stressed the importance of reducing the overuse of antibiotics in agriculture, where they are often used to promote growth in animals and to prevent disease, leading to the spread of resistance. So what can be done to combat this growing crisis? One strategy is to reduce the overuse of antibiotics, by only using them when necessary and as prescribed by a doctor. Another strategy is to develop new antibiotics that bacteria have not acquired resistance to, such as teixobactin, as well as alternative treatments for bacterial infections, such as bacteriophages (viruses that infect and kill bacteria). By learning about antibiotic resistance and the efforts to combat it, you can play a role in protecting global health and preserving the effectiveness of antibiotics for future generations.
Horseshoe crabs, a resilient species that has existed for over 450 million years, are facing heightened pressures due to the booming global demand for their blue blood.

Frances Oldham Kelsey was a scientist who saved thousands of lives by rejecting an application to sell a drug called thalidomide. The drug was widely used in dozens of countries to treat insomnia, workplace stress, and nausea in pregnant women. However, Kelsey found the data on thalidomide's absorption and toxicity inadequate and rejected the application. Her earlier animal-based research demonstrated that drugs could pass from mother to fetus through the placenta, and she believed that thalidomide could cause harm to fetuses. Her decision to reject the application and ask for better evidence saved countless babies from severe birth defects caused by thalidomide. Kelsey's legacy endures as she prioritized facts over opinions and patience over shortcuts, making evidence-based medicine the foundation of reforms that continue to protect people today. By learning about Kelsey's story, students can understand the importance of evidence-based research and the impact of their decisions in science and medicine.

Organ transplants are a life-saving medical breakthrough that have revolutionized the field of medicine. Kidneys are essential organs that filter waste material from the blood and process it into urine. A typical dialysis patient has a poorer life expectancy than many cancers. Removing one kidney should not affect someone's lifespan or quality of life. A kidney from a living donor in general will have a much better quality because it comes from a healthy and tested person. Kidneys are expected to survive up to twice as long on average in the recipient. Currently, it's not allowed to donate a kidney under any form of payment. However, incentivizing people to donate more is actually a way to starve black markets. It's not to recreate them, it's to undermine them. If you reward a person amply for the sacrifice they've made, something they go into with their eyes open and well informed, that's not exploitation. Organ donation is an incredible gift that can save someone's life so palpably, and everyone should consider donating.

Cancer is a mysterious and creepy thing, and understanding it is crucial to fighting it. Cancer cells are unstable and selfish, only working for their own short-term benefit. They trick the body into building new blood vessels to feed them, but this can also become their undoing as they continue to mutate. Large animals seem to be immune to cancer, which scientists explain through two main ways: evolution and hypertumors. Evolution means that large animals invest in better cancer defenses, while hypertumors are the tumors of tumors. The solution to the paradox may actually be something different, but researchers still aren't sure what it is. Learning about the nature of cancer cells and cancer defenses can help you understand this complex and important topic.
Vaccines are likely the most important public health intervention of the last 100 years, having saved over a billion lives.

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.
