Lightning Can Trigger Nuclear Reactions, Creating Rare Atomic Isotopes (sciencemag.org)

sciencehabit shares a report from Science Magazine: Rare forms of atoms, like carbon-13, carbon-14, and nitrogen-15, have long been used to figure out the ages of ancient artifacts and probe the nuances of prehistoric food chains. The source of these rare isotopes? Complicated cascades of subatomic reactions in the atmosphere triggered by high-energy cosmic rays from outer space. Now, a team of scientists is adding one more isotope initiator to its list: lightning. Strong bolts of lightning can unleash the same flurry of nuclear reactions as cosmic rays, the researchers report in Nature. But, they add, the isotopes created by these storms likely constitute a small portion of all such atoms -- so the new findings are unlikely to change the way other scientists use them for dating and geotracing.

    One of the few articles that are actually related to science. Not a clickbait headline... and there are no comments. I get that real science isn't "sexy" but it'd be nice to see a discussion about what this discovery could mean. What are the wild ideas for using lightning to create this isotope? What are the new possibilities? I imagine that we'll be able to generate them artificially, so what can be done with them? IANA Physicist but there used to be some here, and their comments were always welcomed and interesting.

    "It's really not that big of a deal, when you consider what happens in some parts of the world. Isis killed 300+ in a mosque in Egypt. These are fellow muslims. "

    Fellow? Hardly. They were Sufis, apostates.

    "They are subhuman animals."

    You mean like Christians, who made war among themselves for hundreds of years because of some minor differences in interpretation of non-existent gods?
