Learn why two different species of rodents, called voles, have very different strategies for post-mating relationships.
In this Science Update, you’ll hear about a group that’s working to unravel the mystery of how human genes generate such a large number of proteins.
In this Science Update, you’ll hear how genetically engineered tomatoes may be able to resist parasitic worms without the use of toxic pesticides.
In this Science Update, you’ll hear how scientists can measure the way we process language by observing people’s eye movements.
We’ve always been warned not to look at the sun, for fear of burning out the cells in our retinas. It turns out that even photodetectors—devices specially designed to measure light—can’t look at the sun either, but for a different reason: they’re rendered useless when flooded with the sun’s intense rays. In this Science Update, you’ll hear about a new photodetector that’s not afraid to stare the sun straight in the eye.
Many diseases don't develop noticeable symptoms until they've already done considerable damage. That's why doctors would like to get a closer look at the first signs of disease: tiny changes in the way our cells communicate with each other. In this Science Update, you’ll hear about an innovative plan to get closer to those early distress signals.
Researchers are using hamsters to understand the roots of aggression.
Many people now get their DNA tested for hereditary diseases, including Huntington’s Disease and some cancers. But soon, DNA may also be used to diagnose infectious diseases, from salmonella to HIV. In this Science Update, you’ll hear about a developing technology that could make this possible.
Learn how Astronomers study the past by using a powerful telescope to measure light that has been traveling for billions of years.
In this Science Update, hear how scientists are creating new ways to separate toxic waste and dangerous chemicals from the environment.
In this Science Update, hear about a researcher who’s helping tomato plants fight back against black mold.
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.
Most people don't pay much attention to crayfish unless they're piled high on a plate and served with melted butter. But one scientist is using the spiny crustacean to learn how social interaction can change the very chemistry of our bodies. Find out how in this Science Update.
In this Science Update, you’ll hear about researchers who are studying exactly what happens in the brain when it learns and remembers information.
Hurricanes cycle through long periods of high and low activity.
