All Stories by Bethany Brookshire

  1. Genetics

    What we can — and can’t — learn from our pets’ DNA

    Your dog or cat’s DNA is an open book. DNA tests tell people about their pet’s breed and attempt to predict things about its behavior and health.

  2. Genetics

    Explainer: How DNA testing works

    Lots of companies will now test DNA from people and their pets. How do these gene-sequencing techniques work? We explain.

  3. Genetics

    DNA testing looks into dog breeds and cat history

    Dog and cat breeds can look very different from one another. How does it happen? Combinations of tiny genetic tweaks.

  4. Animals

    Scientists Say: Extinction

    When the last member of a species dies, it’s gone forever. That species is extinct.

  5. Chemistry

    Scientists Say: pH

    pH is a scale used to measure the acidity or alkalinity of a solution. The scale ranges from zero to 14, with seven as the perfect neutral middle.

  6. Health & Medicine

    Cool Jobs: Soaking in sweat

    These three scientists are using sweat to hunt killers, detect illness and find out just how our species became such hairless, perspiring apes.

  7. Chemistry

    Explainer: The bacteria behind your B.O.

    Special glands in our armpits give us our signature stink. But it’s not our sweat that’s to blame. It’s the bacteria that gobble it up.

  8. Scientists Say: Mineral

    Minerals are chemical elements or compounds that form repeating crystal structures. Quartz is a mineral. Table salt is, too.

  9. Health & Medicine

    Scientists Say: Olfactory

    Smell something? Thank your olfactory sense. Olfactory refers to anything having to do with smell.

  10. Animals

    Scientists Say: Hertz

    Frequency is how often something repeats over a period of time. Frequency is often measured in hertz, the number of times a cycle repeats each second.
