    All mice are the same, until they’re not

    A new study shows substantial differences in how two closely related mouse strains respond to drugs. It offers new options for linking genes and behavior and may change how scientists think about the similarity of their mouse strains.

    MRSA strain swiped skin bacteria genes to survive

    A common strain of the dangerous microbe may be a wolf in sheep's clothing.

  7. Genetics

    You are what your dad ate, perhaps

    Your development is affected by what your mother ate while she was pregnant with you. Is it also affected by what your father ate? A new study suggests that folate deficiency in dads can affect their offspring through epigenetic changes.

    DNA changes may show how whales adapted to water

    Comparing the genetic material of whales has revealed DNA changes that may have helped the animals adapt to aquatic environments.

  11. Neuroscience

    Gene that boosts Alzheimer’s risk might protect against it too

    Carrying certain genetic versions of apolipoprotein E is a major risk factor for Alzheimer’s disease. A new study looks at the effects of different types of APOE on the major markers of Alzheimer’s in mice and shows that all forms are not equal.
