Given the way that Mark S. George describes the early days of his experiments with transcranial magnetic stimulation (TMS), potential patients might be wary. A professor of psychiatry at the Medical University of South Carolina and a pioneer of TMS, George recounts, for example, how the electrical circuits delivering current to coils would explode “with a blue flame” not all that far from the subject and the scientist.

For a number of years, I have argued that we are now, thanks to the effects of human-caused warming, experiencing a new class of monster storms—”category 6” hurricanes. That is to say, we are witnessing hurricanes that—by any logical extension of the existing Saffir-Simpson scale—deserve to be placed in a whole separate, more destructive category from the traditionally defined (category 5) “strongest” storms. Up until now, that was really just a matter of opinion (1).

The shape of Nature’s stingers revealedEdited by William Nix, Stanford University, Stanford, CA; received September 19, 2023; accepted December 6, 2023SignificanceAs ubiquitous defense mechanisms in Nature, stinger-like structures cover a size range over six orders of magnitude. While their composition varies, we uncovered a common geometric trait: a non-linear relationship between diameter and distance from the tip, following a power law with an exponent universally between 2 and 3.
