Genetics

Scientists can study stress by observing people who suffer from it. What are the physiological changes these people undergo, if any? Is their appetite normal? And what about the heart rate? Lots of observations are possible, meaning there a lot of ways…

-- Have you ever considered that your body is its own ecosystem? Our bodies are host to countless microbial organisms, which live in and on every conceivable part of our body and outnumber our human cells ten to one. We depend on these microbes for a…

-- To unearth the secrets of our human origins, scientists are delving deep into the prehistoric record to find the last common ancestor of great apes and humans, while simultaneously looking in more recent history to define when and where modern humans…

Presented by Vini Mani, Ekaterina (Kat) Pak, and Dima Ter-Ovanesyan In 2011, the FDA approved 35 new drugs–one of the highest approval volumes in the past decade. Drug development is a long and costly undertaking that involves integrated efforts…

-- Of the trillions of cells that compose our body, from neurons that relay signals throughout the brain to immune cells that help defend our bodies from constant external assault, almost every one contains the same 3 billion DNA base pairs that make up…

Presented by Jacob Sargent, Ben Morris, and Thomas Graham DNA serves as the blueprint for all living organisms on earth, but unlike most blueprints, DNA is constantly being damaged and repaired. Factors such as UV light from the sun and chemicals in…

-- Behind every Olympic victory is an incredible amount of physics, biomechanics, and engineering. With the Olympic Games in full swing, let’s take a look at the science behind three of its most popular events: running, swimming and gymnastics.

-- Humans are remarkably close-knit, genetically: of the genetic information that can differ from person to person, less than 10% of this variation is specific to any particular population, while the remaining 90% of differences are seen throughout all…
