Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

    Scientists watch germs evolve into superbugs

    To study how bacteria can evolve resistance to a wide variety of drugs, scientists spread the germs on a food-filled plate the size of a foosball table. Then, they watched resistance rise.

    Bananas under attack: Understanding their foes

    Fungal blights threaten the world’s most popular fruit. But genetic studies hint at new ways to combat some of these diseases.

    How a moth went to the dark side

    Peppered moths and some butterflies are icons of evolution. Now scientists have found a gene responsible for making them so.

  4. Genetics

    Why some frogs can survive killer fungal disease

    A disease is wiping out amphibian species around the globe. New research shows how some frogs develop immunity.

  5. Genetics

    Genes: How few needed for life?

    Scientists rebuilt a microbe using its old genes. But not all of them. They used as few building-blocks as they could get away with and still have the life-form survive.

  6. Animals

    Cool Jobs: Pet science

    Pets make great subjects for research. These scientists work to make our animals — and us — healthier and happier.

    Gene editing swats at mosquitoes

    A new genetic technique can render insects that spread malaria unable to reproduce.

  8. Agriculture

    New gene resists our last-ditch drug

    Antibiotic resistance continues to grow. Now, scientists have found a tiny loop of DNA that resists a drug doctors use as a last line of defense.

  9. Genetics

    Gene editing creates buff beagles

    Scientists showed that a potentially useful new gene-editing tool can work in dogs. It created a pair of adorable, muscular puppies. But the goal is to use it for other research purposes.

    Trio gets chemistry Nobel for figuring out DNA repair

    Three researchers have won the 2015 Nobel Prize in chemistry for working out how cells fix damaged genetic material.

    New treatments may rally ex-president’s fight against cancer

    Former President Jimmy Carter has a potentially lethal type of skin cancer that has already spread to his liver and brain. Recent improvements in medicine may help him fight it.
