by Piyush Nandafigures by Shreya Mantri Gravity has been apparent for thousands of years: Aristotle, for example, proposed that objects fall to settle into their natural place in 4th century BC. But it was not until around 1900, when Issac Newton explained gravity using mathematical equations, that we really understood the phenomenon. Why didn’t thinkers before Newton think about gravity the way he did? Scientific … Continue reading Solving Scientific Problems by Asking Diverse Questions
by Edward Chen The COVID-19 pandemic has catalyzed rapid technological advancements as scientists and engineers mobilize to combat its toll on human lives. Time is of the essence, and after rigorous testing for safety and effectiveness, there are now 3 vaccines with emergency approval in the United States that are all based on relatively new concepts. Two of the vaccines are based on messenger RNA … Continue reading How do COVID-19 vaccines work? Hear from a researcher who helped develop the Johnson & Johnson vaccine.
New data-driven RNA simulations allow scientists to observe twisting and folding in real time. Continue reading RNA Simulations Show Its Unique Ability to Move and Fold
by Francesca Tomasifigures by Jovana Andrejevic Right now, the world is eagerly awaiting clinical trial data for two candidate COVID-19 vaccines known as mRNA vaccines. mRNA stands for “messenger RNA,” referring to the molecule that the vaccine delivers to our bodies. Once the vaccine enters our cells, the mRNA tells them exactly how to build a piece of the SARS-CoV-2 virus. The vaccine itself cannot … Continue reading An Introduction to Ribosomes: Nature’s busiest molecular machines
