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 […]

Reading Time: 10 minutesEstrogen is often called the body’s “architect of balance.” From the first stirrings of puberty to the steady rhythm of adulthood, this hormone quietly shapes bones, skin, heart, and brain. It is produced mainly by the ovaries, but also by the adrenal glands and, later in life, by fat tissue that keeps a gentle baseline […]

Following the death of Louis XIII, France entered a period of regency under Queen Anne of Austria. The queen’s decision to retain Mazarin as her chief minister shaped the nation’s political landscape for nearly two […]

Reading Time: < 1 minuteAs the amino acid chain grows, it folds into a three-dimensional (3-D) structure, which depends on both the chemical nature and order of the different amino acids. The 3-D structure determines the function of the protein. When there is a change in one or more amino acids, then the ability of the protein to function […]
