The water crisis is one of the most pressing threats to humanity in the 21st century. According to recent data, more than 2.2 billion people lack access to safe drinking water and 3.5 billion do not have safely managed sanitation services. This situation not only compromises the health and well-being of millions, but also hinders the economic and …

The war in Ukraine has triggered a global food crisis that goes beyond cereal shortages: it has jeopardized the supply of fertilizers, a key pillar of modern agricultural production. Before the conflict, Russia and Belarus jointly accounted for around 33% of global potash exports, an essential fertilizer component. In addition, Russia was responsi…

Mental health is one of the major healthcare challenges of the 21st century. The rising number of cases of anxiety, depression, and neurodegenerative disorders has driven the search for new diagnostic tools and more effective treatments. In this context, although often overlooked, chemistry plays a key role in understanding and managing these cond…

A Growing Challenge in Food SafetyFood allergies have increased significantly in recent decades, especially in industrialized countries. Although there is no single clear cause, experts point to multiple factors: changes in diet, reduced exposure to microorganisms during childhood (hygiene hypothesis), increased consumption of ultra-processed food…

The transition towards a more sustainable economy has driven unprecedented demand for advanced batteries, essential for electric vehicles, renewable energy storage, and electronic devices. However, this growing demand has highlighted significant challenges in the supply chain of critical materials such as lithium oxide (Li₂O) and manganese dioxide…

Marie Maynard Daly made history by becoming the first African-American woman to earn a PhD in Chemistry in the United States—a milestone that opened doors for countless women and underrepresented communities in STEM fields. Beyond this historic achievement, Daly’s pioneering research on cholesterol and hypertension transformed our understanding of…

The soft drinks we now enjoy from any supermarket or restaurant have a surprisingly chemical origin. Long before they became popular beverages, sodas were invented in laboratories by pharmacists and chemists seeking to replicate natural mineral waters with medicinal properties. But how did we go from pharmaceutical remedies to the most consumed ca…

3D printing, also known as additive manufacturing, is revolutionizing a wide range of industries, from aerospace to healthcare. The technology's ability to create precise, custom objects layer by layer has made it indispensable in research and development (R&D), particularly in laboratory settings. This article explores the role of 3D printing…

The Science Behind the Conquest of SpaceTravelling to space is not only a feat of engineering, but also an achievement of chemistry. Without it, rockets would not launch, astronauts would have no oxygen to breathe, and spacecraft would not withstand the extreme conditions of the cosmos. Every mission, from the earliest expeditions to the explorati…

Elements such as neodymium, yttrium, and dysprosium are essential in the manufacture of high-power magnets, electric vehicle batteries, and LED screens, but their extraction is complex and costly due to their uneven distribution in the Earth's crust.The scarcity of chemical elements and its impact on industry:Unlike common metals such as iron or c…
