  1. Working Hypothesis

    Slower to die

    A strain that lasts longer under heat might be better at coping, or worse at giving up. The measurement can't tell you which.

  2. Uncontrolled VariablesLanguage

    Little crumb

    Two names for the same organism, both of them about being broken.

  3. Uncontrolled VariablesLanguage

    False colour

    The pigment that makes diatoms golden is named, if you follow it far enough, after eye makeup.

  4. Uncontrolled VariablesLanguage

    Stitched together

    A seam, a suture, an epic poem and a slit in a shell, all from the same verb.

  5. Working Hypothesis

    Copy number

    A population under heat ends up with twice the genome it started with. Whether the heat caused that or merely revealed it are opposite stories.

  6. Working Hypothesis

    Path length

    A sealed glass box with no limbs, moving on purpose. Three papers this year on how, and one on where it stops.

  7. Working Hypothesis

    Within error

    One clonal culture, split 384 ways, and the copies disagreed with each other. It was reported as a caution rather than a result.

  8. Working Hypothesis

    Trophic mode

    A common ocean diatom appears to be getting a lot of its carbon from somewhere other than sunlight. Nobody has watched it happen yet.

  9. Working Hypothesis

    Resting stage

    Cells that sank into the mud sixty years ago can be woken up and grown. That gives you something almost no experiment ever gets: a control group from the past.

  10. Uncontrolled VariablesLanguage

    False friend

    A genus named for looking like something else, and a poison named after a folk remedy.

  11. Working Hypothesis

    Mass balance

    The ocean's nitrogen accounts have never quite added up. One of the missing contributors turns out to be living inside another organism.
