A team of researchers from UCLA has developed a new remote diagnostic technique that overcomes bias against darker skin tones in heart rate measurements. By combining the light-based measurements of a camera with radio-based measurements from radar and refining them through machine learning, the new technique improves the accuracy and fairness of heart rate readings for patients across a wide variety of skin tones. The study's findings, recently published in the journal ACM Transactions on Graphics, offer a promising path toward achieving more accurate and equitable remote technologies that can be used to remotely monitor patients both in clinical settings and from patients’ homes.

Blindness doesn't stop people from having interests, passions, and desires. In fact, losing one sense can lead to a sharpening of others, as blind people learn to rely on their hearing, touch, and other senses. They still care about their appearance, their love for shopping, and still have hobbies like makeup and beauty. Blind people can work and lead fulfilling lives, and they appreciate kindness and support from others. As a student, learning about different experiences and perspectives can broaden your understanding of the world and help you develop empathy and respect for others. Exploring academic topics related to disability and accessibility can also prepare you for a more inclusive and equitable future, whether you pursue a career in medicine, technology, or social justice.

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.

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.

Scotland has become the first country to ban desflurane, an anaesthetic gas with a global warming potential 2,500 times greater than carbon dioxide, from its hospitals due to its environmental threat. The move would cut emissions equivalent to powering 1,700 homes a year. UK hospitals have already cut down, with over 40 hospital trusts in England and some in Wales having stopped using it. NHS England will introduce a similar ban from 2024. Anaesthetists have switched to safer alternatives, but more needs to be done to reduce the NHS's carbon footprint.

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.

Waste management is an essential aspect of public health, and it has a long and fascinating history.

Electricity is a fundamental part of modern life, but could too much of it be harmful? Understanding the movement of electric charges and resulting electromagnetic radiation is key to answering this question. While some radiation, like UV light and X-rays, can be dangerous, most of the radiation emitted by human technology, such as mobile phones and household appliances, is harmless. However, some studies have suggested possible long-term harm from constant exposure to weak electromagnetic radiation. The debate surrounding this issue highlights the importance of reliable scientific studies and responsible communication of findings. Learning about the effects of electromagnetic radiation can help students make informed decisions about their technology use and contribute to ongoing scientific research.
