Dolphins and other marine mammals have pretty big brains compared to the size of their bodies. That’s one indication of high intelligence, and anyone who has seen them perform at an aquarium or zoo can attest to that fact. This Science Update introduces us to one scientist who’s trying to find out how dolphins got so brainy.
In this Science Update, find out if reading in low light will wreck your eyes.
In this Science Update, hear how microbes can travel from country to country on clouds of dust.
In developing areas of the world, including parts of Asia, rapid industrialization has brought about more cars, more factories, and more people to burn coal and wood for cooking purposes. Those activities throw a lot of soot and other pollutants into the air. In this Science Update, you’ll hear about an effort to measure the pollution over Asia and assess its impact on humans and the environment.
Scientists measure the nitrate levels in groundwater and determine whether the lawn fertilizers raised those levels significantly.
In this Science Update, learn how a master model of Southern California geology can help predict earthquakes.
