Health Capsule Arsenic is a naturally found substance present in the environment, including in soil, water, and air. However, prolonged exposure to arsenic can have serious health effects. Many communities still depend on drinking water that contains arsenic at harmful levels. Recent research indicates that reducing arsenic exposure can significantly decrease the risk of dying from cancer and heart-related conditions. The study observed a group of adults in Bangladesh over a period of 20 years.

Health Capsule It's common for patients to experience anxiety before undergoing surgery. However, high stress levels can hinder the body's natural healing process. Increased stress can lead to more inflammation, which is the body's way of protecting itself during injury or illness. Fortunately, there are steps you can take to boost your health ahead of a surgical procedure. This proactive approach is known as prehabilitation. Recent research has found that tailored

Common Names: Grape seed extract Scientific Name: Vitis vinifera Background • Derived from the seeds of grapes used in winemaking, grape seed extract is widely used as a supplement. It is often advertised for benefits such as lowering blood pressure and cholesterol, and is also used in topical applications for wound care and oral health. • The extract is high in proanthocyanidins, compounds known for their potential positive health effects. How Much Do We Know? • There has been moderate

Common Names: goldenseal, yellow root, goldenroot, yellow pucoon Scientific Name: Hydrastis canadensis Background • Goldenseal is a herbaceous plant found in the northeastern parts of the United States and southeastern regions of Canada. It is known for its characteristic yellow underground stem, called a rhizome. Due to overharvesting in the wild, natural supplies have diminished, making it a rare and pricey crop even when farmed. • Indigenous peoples have traditionally used goldenseal to

On 20 January 2026, the World Health Organization (WHO) welcomed a group of parliamentarians to its Geneva headquarters for an important exchange focused on women’s health, enhancing sexual and reproductive health and rights (SRHR), tackling noncommunicable diseases (NCDs), and discussing the path forward for global health cooperation. The meeting was organized in collaboration with the Konrad-Adenauer-Stiftung (KAS) and the UNITE Parliamentarians Network for Global Health. Participants

Common Names: Ginkgo, Ginkgo biloba, Maidenhair tree, Fossil tree, Japanese silver apricot Scientific Name: Ginkgo biloba Background • Ginkgo is a very old tree species, often referred to as a “living fossil” because it is the only surviving representative of an ancient plant group. Traditionally, it has been used in Chinese medicine to treat health issues like coughs and diarrhea. • Today, ginkgo leaf extract is commonly used and marketed as a supplement, believed to support various health

Understanding the Side Effects of Cancer Treatments Cancer occurs when abnormal cells grow and divide uncontrollably, making it hard for the body to manage them. Chemotherapy, often referred to as chemo, involves using medications designed to destroy these fast-growing cancer cells or stop their growth. However, since chemo targets rapidly dividing cells, it can also affect healthy ones, leading to a variety of side effects. Researchers are actively working on ways to minimize these effects on

Understanding Seizures and Epilepsy Wave of Neural Activity Inside your brain is a highly intricate web of nerve cells known as neurons. These neurons transmit signals that govern your senses, movements, and emotions, allowing your body to function and interact with your surroundings. Occasionally, this system can malfunction. Large numbers of neurons may send excessive signals all at once, causing an unusual spike in brain activity called a seizure. Experiencing even a single seizure warrants

Joint Statement from UN Leaders on the International Day of Zero Tolerance for Female Genital Mutilation In 2026 alone, approximately 4.5 million girls—many of them under five—face the threat of undergoing female genital mutilation (FGM). At present, more than 230 million girls and women live with the enduring impact of this harmful practice. On this International Day of Zero Tolerance for Female Genital Mutilation, we renew our shared commitment to eliminate FGM completely. We stand united to

Credit: Schoklitsch - TU Graz Insulated joints might not be widely recognized, but they are essential for railway operations. These joints electrically separate sections of the rail network, allowing systems to detect when trains enter or leave a specific segment. Only once a section is confirmed clear can the next train proceed. Austria currently has about 33,000 of these joints, but on

Image: Artistic reconstruction of Foskeia pelendonum Illustration by Martina Charnell Fossils belonging to at least five individuals were discovered by Fidel Torcida Fernández-Baldor from the Dinosaur Museum in Salas de los Infantes. “From the outset, we realized these remains were unusual because of how tiny they were. What’s more, studying this species has changed our broad understanding of ornithopod dinosaur evolution,” he remarked. The new dinosaur was named Foskeia, a term inspired by

2025 Global Health Simulation Exercises In 2025, countries within three regions under the World Health Organization (WHO) actively engaged in large-scale simulation exercises designed to evaluate and enhance their implementation of the International Health Regulations (IHR). These drills were designed to strengthen their capacity to detect, notify, and manage public health events that could pose international concerns. The simulations — known as SAPHIRE in South-East Asia, JADE in the European

Health Capsule Many people in the United States are not getting enough physical activity. Not moving enough can increase the risk of long-term health issues like heart disease, diabetes, and certain types of cancer. Recent research shows that the way your neighborhood is built may influence how much you walk each day. Walking is a great way to stay healthy. However, not all communities are designed to support walking. Some areas may not have sidewalks, green spaces, or convenient shops that
