  • And a much clearer version only needs two more words:

    Remains of Antarctic researcher, who worked for Falklands’ Dependency 66 years ago, found in receding glacier

    I agree that it was a good article, though. Editors must have to take a class in headline obstruction.

    Edit: maybe I’m wrong; there are many better headlines about this story. The one OP found is uniquely bad:

    • Remains of British researcher lost in 1959 recovered from Antarctic glacier
    • Melting ice reveals remains of Antarctic researcher who vanished 66 years ago
    • Body of Antarctic researcher found 66 years after he disappeared exploring glacier
    • Remains of U.K. researcher who vanished in 1959 found on Antarctic glacier: “Shocked and amazed”
    • Remains of a Lost Antarctic Researcher Are Finally Recovered, 66 Years After He Fell Into a Crevasse
    • After 66 Years, Melting Glacier Releases Antarctic Researcher’s Remains
    • Lost researcher’s remains found on Antarctic glacier after 66 years
    • Remains Of Antarctic Researcher Lost During 1959 Expedition Found After 65 Years

  • pH is the negative of the (base 10) logarithm of the activity of H+: pH = -log10(aH+)

    If you mean “what’s the difference between concentration and activity,” activity is the “effective concentration” of a species. For ideal solutions, activity is equal to concentration. For real solutions, interactions between the components in the solution may cause a species to “act” like it is more or less concentrated.

    Dilute solutions at standard conditions are close to ideal: activity is about equal to concentration. But consider a concentrated solution of a salt: the activity will tend to be lower than the concentration because the cations and anions are not completely independent as in an ideal solution, but tend to “shield” each other due to electrostatic forces.
