Health Capsule From a biological perspective, individuals do not all age at the same pace. The speed at which you age can influence your overall health and the likelihood of developing certain diseases. Understanding how quickly you age could provide an opportunity to work with your healthcare provider to potentially delay aging. Recently, researchers have created a method to estimate aging progress using a single brain scan. This team had previously explored measuring biological aging through

The World Health Organization (WHO) has issued a new report entitled “Saving lives, spending less,” highlighting that a modest annual investment of just $3 per person in combating noncommunicable diseases (NCDs) could produce economic returns reaching $1 trillion by the year 2030. In addition, WHO presented a new review of national progress in reducing deaths from NCDs between 2010 and 2019. Although 82% of countries saw declines in mortality over that period, progress has generally slowed

Image credit: Anne Weston, Francis Crick Institute A research team led by Christian Baumgartner from the Institute of Health Care Engineering at Graz University of Technology (TU Graz) has created an advanced digital replica of the A549 lung cancer cell line. This digital twin focuses on detailed simulations of internal bioelectric functions and calcium signaling processes. Calcium plays a critical role in cellular function and

Every child has the right to receive safe, high-quality medical care from the very beginning of life. Despite this, millions of children around the globe continue to be underserved by health care systems that are ill-equipped to cater to their specific needs. On World Patient Safety Day 2025, the World Health Organization (WHO) is calling for immediate and decisive action to make health care safer for children, under the theme, “Patient Safety from the Start!” This year’s initiative brings

The World Health Organization (WHO) has released its global cholera update for 2024, revealing a rise in both infections and fatalities caused by the illness. In 2024, cholera cases grew by 5% and deaths spiked by 50% compared to the previous year, with over 6,000 fatalities reported from a disease that is both avoidable and treatable. Despite these troubling statistics, experts believe the actual numbers are even higher due to underreporting. Ongoing challenges such as conflict,

WHO Guidelines on Multiplex Testing The World Health Organization (WHO) is forming a Guideline Development Group (GDG) to produce data-driven recommendations regarding multiplex testing. This initiative aims to establish key frameworks for integrated diagnostic services, focusing on updated research concerning HIV, viral hepatitis, and other sexually transmitted infections (STIs). Reliable and prompt diagnostic services play an essential role in halting, identifying, and treating HIV,

Q&A Highlights from a discussion with Dr. K.C. Brennan, a specialist in migraines and headaches at the University of Utah. NIHNiH: What is your method for treating migraines? Brennan: Migraine is a disorder involving networks throughout the brain, so treatment needs to take the entire person into account in order to be effective. Many areas of the nervous system are overstimulated during a migraine. This heightened sensitivity affects how we experience light, sound, and even smell—making

Understanding Its Role in Health Maintenance While many people are familiar with taking aspirin to relieve pain or bring down a fever, some individuals take a small daily dose for a different reason. A consistent low-dose regimen of aspirin has been found to lower the chances of serious heart-related issues such as heart attacks and strokes. However, researchers have discovered that the effectiveness of aspirin can vary depending on a person’s age and general health status. Aspirin works by

The World Health Organization (WHO) has released a new report emphasizing the damaging effects of tobacco on child development, particularly its contribution to child stunting—a condition that affects approximately 150 million children globally, mostly in regions such as Africa and Asia. Stunting heightens the risk of illness, developmental delays, and even early mortality. This latest release is the eleventh in a series of summaries about tobacco-related health issues and is aimed at

Heart and blood vessel diseases, known collectively as cardiovascular diseases, are the leading cause of death in the United States. Among these, coronary heart disease — also referred to as coronary artery disease — is the most widespread. This condition arises when the arteries that bring blood to the heart muscle become restricted or clogged. • Various natural and alternative methods have been explored to determine if they may help manage risk factors like high blood pressure and elevated
