Reading Time: 5 minutesTo map the human brain is to attempt something extraordinary: to draw a chart of the biological structure that gives rise to thought, emotion, memory, imagination, and identity. For centuries, philosophers speculated about the seat of the self. Today, neuroscientists trace neural circuits, visualize functional networks, and chart synaptic pathways in search of answers to […]

Reading Time: 5 minutesIf life had a hidden workforce, enzymes would be its most essential employees. Every breath you take, every thought you form, every bite of food you digest depends on thousands of tiny molecular machines working with extraordinary precision. These machines are enzymes. Without them, the chemistry of life would move so slowly that cells could […]

Reading Time: 4 minutesFor decades, genes were often described as a fixed blueprint that determined who we are and how our bodies function. According to this view, DNA acted as destiny, setting limits that environment could influence only at the margins. Modern biology has shown that this picture is incomplete. While the DNA sequence itself usually remains stable, […]

Reading Time: 3 minutesProteins are essential biomolecules that perform a vast array of functions in living organisms. From catalyzing chemical reactions to providing structural support, proteins are involved in nearly every biological process. But what happens when proteins don’t fold correctly? The answer lies at the heart of many devastating diseases. In this article, we explore the science […]

Reading Time: 7 minutesWaves are everywhere. We hear them as sound, see them as light, feel them as ocean swells, and rely on them every time we use Wi-Fi or a mobile phone. Beneath all these different phenomena lies a common language: the mathematics of waves. Once you understand that language, very different parts of the universe start […]

Reading Time: < 1 minuteThe Math Ebook Viewer is an HTML5-based web app that reads BSON books with mathematical expressions. It works in modern browsers on both desktop and mobile devices and requires no traditional installation—just open a supported browser and visit one of the links below. You can then import book content for offline reading (no internet connection […]

Reading Time: 4 minutes3-6. Addition of Velocities Learning Objectives Apply principles of vector addition to determine relative velocity. Explain the significance of the observer in the measurement of velocity. Relative Velocity If a person rows a boat across a rapidly flowing river and tries to head directly for the other shore, the boat instead moves diagonally relative to […]

Reading Time: 4 minutesThe image above comes from Gulliver’s Travels — the moment when the giant Gulliver awakens to find himself tied down by hundreds of tiny ropes, captured by the miniature people of Lilliput. Though it belongs to the world of fiction, the scene offers a surprisingly powerful metaphor for how small genetic changes can shape — […]

Reading Time: 2 minutesMost people think of hereditary cancers as running in families — passed down from one generation to the next. But not all genetic changes are inherited. Sometimes, a completely new mutation appears for the first time in a person, even though their parents don’t carry it. These are known as de novo mutations. A de […]

Reading Time: 12 minutesEvery cell in the human body carries a vast instruction manual—its genome. Within those three billion letters of DNA lie the directions for how a cell grows, divides, repairs itself, and eventually dies. Cancer genomics studies what happens when parts of that manual are misprinted, missing, or rearranged. These genetic changes can transform healthy cells […]
