Could it be that human existence depends on gravitational waves? Some key elements in our biological makeup may come from astrophysical events that occur because gravitational waves exist, a research team headed by John R. Ellis of Kings College London suggests.
The headline is referring to the fact that iodine and bromine are products of neutron star collisions, it is just really bad writing as often happens with science reporting. The original paper is more clear, probably should’ve just linked to it in the first place https://arxiv.org/abs/2402.03593
That makes sense, thanks for the link! Will give it a read later :)
