> A high-speed camera clearly showed one strike following the straight line of the laser beam, rather than taking a branching path. Why isn't the picture poste

  Probably because "following the straight line of the laser beam" should have a "for a bit" at the end; the lightning only goes (relatively) straight for a short distance so it doesn't look very impressive. You can see the picture they are talking about here: https://www.nature.com/articles/s41566-022-01139-z/figures/3 https://www.nature.com/articles/s41566-022-01139-z/figures/3 And this one shows two other examples of similar strikes along with the laser drawn on top: https://www.nature.com/articles/s41566-022-01139-z/figures/2 https://www.nature.com/articles/s41566-022-01139-z/figures/2

    What do you mean it doesn't look impressive? If you can attract the lightning to a lightning rod to prevent it from hitting other targets like sporting fields with lighting equipment and bipedal fleshy beings from getting struck, then seems like a very impressive thing to me.

  It is! The link goes to a “News and Views” summary (more background, less data) rather than the original article. Check out Figure 2 of the original article to see lightening being diverted https://www.nature.com/articles/s41566-022-01139-z/figures/2 https://www.nature.com/articles/s41566-022-01139-z/figures/2 Here’s the reference if you want to read the whole thing (it’s open access) Houard, A., Walch, P., Produit, T. et al.
