Science Updates

  • Tree Torture

    Tree Torture 

    In this Science Update, hear about the effects of groundwater pumping on the health of riverbank ecosystems.

  • Monogamous Voles

    Monogamous Voles 

    Learn why two different species of rodents, called voles, have very different strategies for post-mating relationships.

  • Proteome

    Proteome 

    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.

  • Nematodes

    Nematodes 

    In this Science Update, you’ll hear how genetically engineered tomatoes may be able to resist parasitic worms without the use of toxic pesticides.

  • Eye Tracking

    Eye Tracking 

    In this Science Update, you’ll hear how scientists can measure the way we process language by observing people’s eye movements.

  • Solar Blind

    Solar Blind 

    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.

  • Diagnostic Microchip

    Diagnostic Microchip 

    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.

  • Hamsters

    Hamsters 

    Researchers are using hamsters to understand the roots of aggression.

  • Color-Coded DNA

    Color-Coded DNA 

    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.

  • South Pole Scope

    South Pole Scope 

    Learn how Astronomers study the past by using a powerful telescope to measure light that has been traveling for billions of years.

  • Zeolites

    Zeolites 

    In this Science Update, hear how scientists are creating new ways to separate toxic waste and dangerous chemicals from the environment.

  • Tomato Mold

    Tomato Mold 

    In this Science Update, hear about a researcher who’s helping tomato plants fight back against black mold.

  • Dolphin Brains

    Dolphin Brains 

    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.

  • Traveling Dust

    Traveling Dust 

    In this Science Update, hear how microbes can travel from country to country on clouds of dust.

  • Asian Brown Cloud

    Asian Brown Cloud 

    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.

  • Lawn Nitrates

    Lawn Nitrates 

    Scientists measure the nitrate levels in groundwater and determine whether the lawn fertilizers raised those levels significantly.

  • Predicting Earthquakes

    Predicting Earthquakes 

    In this Science Update, learn how a master model of Southern California geology can help predict earthquakes.

  • Crayfish Reflexes

    Crayfish Reflexes 

    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.

  • Word Associations

    Word Associations 

    In this Science Update, you’ll hear about researchers who are studying exactly what happens in the brain when it learns and remembers information.
