    Signs of sleep debt found in the blood

    When rats and people skimp on sleep, fats and acids involved in metabolism dwindle.

  2. Animals

    ‘The Cultural Lives of Whales and Dolphins’ offers window into cetacean societies

    Dolphins and whales pass cultural knowledge to one another, the authors of a new book argue.

  3. Poison frog
    Animals

    Rainforest frogs flourish with artificial homes

    A rainforest frog population grew by about 50 percent when scientists built pools for tadpoles that mimic puddles made by other animals.

  4. Transplaneted cells
    Neuroscience

    Shots of brain cells restore learning, memory in rats

    Scientists healed damage caused to rats’ brains from radiation by injecting cells that replenish the insulation on neurons.

  5. Puppies
    Genetics

    Pregnancy in mammals evolved with help from roving DNA

    DNA that “jumped” around the genome helped early mammals shift from laying eggs to giving birth to live young.

  6. Snake illustration
    Paleontology

    Snakes crawled among Jurassic dinosaurs, new timeline says

    Earliest snake fossils provide evidence snakes evolved their flexible skulls before their long, limbless bodies.

  7. E. coli
    Genetics

    Scientists find new way to corral genetically engineered bacteria

    Engineering E. coli to depend on human-made molecules may keep genetically modified bacteria from escaping into nature.

  8. Flying goose
    Animals

    Mountain migration is a roller coaster for bar-headed geese

    Bar-headed geese rise and fall to match terrain below them when migrating over the Himalayas.

  9. Animals

    Squids edit genetic directions extensively

    In squids, RNA editing means that DNA often does not get the final say in which proteins are created.

  10. greater mouse-tailed bat
    Animals

    ‘Bag of chips effect’ helps bats find a meal

    Bats get a clue to where dinner is by listening to peers attacking prey.

  11. bowhead whale
    Animals

    Bowhead whales may unlock the secrets to a long, healthy life

    Analyzing the genome of the bowhead whale may help scientists understand how the animals live for more than 200 years.

  12. An urban coyote
    Ecosystems

    Cities are brimming with wildlife worth studying

    Urban ecologists are getting a handle on the varieties of wildlife — including fungi, ants, bats and coyotes — that share sidewalks, parks and alleyways with a city’s human residents.
