From the dizzying heights of tightrope walking, we can learn the secrets of balancing and defying gravity. Sonja Harpstead, a tightrope instructor in New York, explains that posture is the key to success, and lowering your center of gravity towards the wire is crucial. By understanding the physics of the human body, tightrope walkers use rotational inertia to keep their balance and carry a long balancing pole to lower their center of gravity even further. Beyond entertainment, research in this area could have healthcare implications, including detecting early muscle degradation in elderly patients and building strength and balance with physical therapy exercises. Take a step into the physics of tightrope walking today!

Sharks may have a key to the future of soft robotics and medical implants. Physicists have discovered how sharks' spiral-shaped intestines work, which led them to 3D print models of the structures to study their fluid dynamics. They found that the soft, elastic materials led to faster fluid flow in one direction, contrary to a basic physics theorem. This discovery could inspire the development of soft robots and medical devices that can deform in different ways, just like an octopus.
Teflon, a material that doesn't stick to anything, was stumbled upon accidentally in 1938 by a chemist named Roy Plunkett. Teflon's properties make it perfect for things that need to be slippery, chemical-resistant, or waterproof, which means it has a lot of applications. It can be found all over the place, from raincoats to industrial ball bearings to artificial joints. The incredible properties of PTFE, the chemical name for Teflon, come from its molecular structure. It's a polymer, meaning it's made of long chains of repeating units of atoms strung together. PTFE has tight carbon-fluorine bonds that ignore the normal, intermolecular forces that help substances stick to each other. Even the famously adhesive feet of geckos usually can't get a grip on it. Learning about the properties of materials like Teflon can inspire independent exploration of science and engineering, which can lead to exciting career opportunities in fields like materials science and chemical engineering.
Scientists have developed a simple and low-cost method to break down almost a dozen types of "forever chemicals" known as PFAS, which have contaminated virtually every drop of water on the planet and are associated with certain cancers and thyroid diseases. By using a chemical guillotine and common solvents and reagents, they severed the molecular bonds in PFAS, gradually nibbling away at the molecule until it was gone, leaving behind only safe byproducts. This breakthrough could eventually make it easier for water treatment plants to remove PFAS from drinking water.

Plastics have become ubiquitous in our daily lives, but few of us know the history behind this versatile material. The first plastic was created in 1863 by an American named John Wesley Hyatt, who invented celluloid, made from cellulose found in wood and straw. This discovery led to a cascade of new plastics, including bakelite, polystyrene, polyvinyl chloride, acrylics, and nylon. Plastics have replaced other materials like wood, glass, and fabric in furniture, clothing, and packaging. While plastics have brought convenience and cost-effectiveness, they have also created staggering environmental problems. Many plastics are made of nonrenewable resources, and plastic packaging was designed to be single-use, but some plastics take centuries to decompose, creating a huge buildup of waste. By learning about plastics, students can understand how science and innovation have shaped our world, and they can explore ways to address the environmental problems associated with plastic use.
Inhaler delivery systems have revolutionized the treatment of respiratory illnesses, making it easier for patients to receive the medicine they need to manage their symptoms. But how do these devices work, and what scientific principles underlie their design? At the heart of an inhaler is the aerosol, a fine mist of medication that is delivered directly to the lungs. To create this mist, inhalers use a propellant, which expands rapidly upon release, creating a burst of pressure that forces the medication out of the device and into the airways. One key challenge in designing inhalers is ensuring that the aerosol particles are small enough to be easily inhaled, yet large enough to deposit effectively in the lungs. This is where the science of aerodynamics comes into play, as researchers work to optimize the shape and size of the particles to achieve the ideal balance of delivery efficiency and patient comfort. Recent advancements in inhaler technology have led to the development of smart inhalers, which use sensors and digital connectivity to monitor patient use and provide personalized feedback and reminders. This innovation has the potential to improve patient adherence and outcomes, and is just one example of how inhaler delivery systems continue to evolve and improve. Leading academics in the field include Dr. Richard Costello, a respiratory physician and clinical scientist at the Royal College of Surgeons in Ireland, and Dr. Omar Usmani, a consultant physician in respiratory medicine at the Royal Brompton Hospital and professor of respiratory medicine at Imperial College London. These experts have contributed to important research on inhaler technology and the treatment of respiratory diseases, and continue to drive innovation in the field. Inhaler delivery systems have revolutionized the treatment of respiratory illnesses, allowing patients to manage their symptoms with greater ease and precision. By understanding the science behind aerosol medicine and the principles that underlie inhaler design, we can appreciate the incredible innovation that has made this possible.
