Submission + - Antimatter in lightning (sciencenews.org)

AMESN writes: The Fermi Gamma-ray Space Telescope launched last year detects gamma rays from light years away, but recently it detected gamma rays from lightning on Earth. And the energy of the gamma rays is specific to the decay of positrons, which are the antimatter flavor of electrons. Finding antimatter in lightning surprised researchers and suggests the electric field of the lightning somehow got reversed.

"Miscalculation" is the wrong word. Geologists are nuanced (unlike this headline) in how they interpret C-13 vs. C-12, especially for early Earth history. The PNAS paper is not about the ratio being flawed, it's about another way to interpret the activity of the shallow ocean versus the deep, open ocean. The paper is simply another line of scientific discussion, itself part of the scientific method.
