1. Archaeology

    After 2,000 years, Ptolemy’s war elephants are revealed

    A genetic study sheds light on world’s only known battle between Asian and African elephants.

  2. Animals

    Jellyfish bloom in spring when winter ‘timer’ dings

    The coordinated appearance of the adult form of the animal is the result of a metamorphosis hormone that accumulates during winter months.

  3. Genetics

    Life at the Speed of Light

    Biology has come a long way from the days of mixing things in petri dishes and hoping something interesting happens. In his new book, Venter introduces readers to a future of precise biological engineering.

  4. Genetics

    Scorpion’s sting evolved from insects’ defensive proteins

    With a single genetic mutation, an insect’s defensive proteins can be transformed into a toxin that gives scorpions their signature sting, a new study shows.

  5. Genetics

    Microbe and human genes influence stomach cancer risk

    When genes of the bacterium and its human host evolve together, the strain is less harmful than that same strain in a person whose ancestors didn't encounter that particular microbe.

  6. Genetics

    Elephant shark genome small and slow to evolve

    The animals have the smallest genome of non-bony fishes and the slowest-evolving genes among vertebrates, a study suggests.

  7. Neuroscience

    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.

    Top genomes of 2013

    Scientists continue to decode the genetic blueprints of the planet’s myriad flora and fauna.

    Year in Review: High court rules against gene patents

    The justices’ decision opens the way for choices in DNA testing.

  11. Plants

    Lone survivor of ancient flowers is gluttonous gene consumer

    The rare Amborella shrub has engulfed whole genomes from other species.

  12. Microbes

    MRSA strain swiped skin bacteria genes to survive

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