Essay: Embryonic DNA Reconfiguration via CRISPR

Just weeks ago on September 28th, Japan’s governmental health and science ministries officially drafted national guidelines on human gene-editing and manipulation experiments, particularly within embryos (Cyranoski, 2018). Before then, Japan’s stance on genetic experiments had remained neutral. Now it is joining an increasing list of countries who support this genetic innovation.             One of the…

Earth Sciences Study Guide: Atmospheres

From Figure 4.2, describe the geographic locations where coastal upwelling is important (e.g., “west central and southwestern South America”). Upwelling causes some of the coldest surface temperatures on Earth. The low surface temperatures stabilize the overlying atmosphere, causing cool dry climates (deserts) to dominate the western edge of South America. Upwelling is important where coastlines…

Modern Physics

During the late 1890s the creation of the quantum mechanics and Einstein’s Relativity beckoned a new age in physics: modern physics.  The terminology of modern physics refers to any branch of physics, such as nuclear physics or electromagnetism, which was developed in the early twentieth century or older branches that were greatly influenced by twentieth…
