The neutrino “fog” is beginning to materialize.

Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two experiments, built to detect particles of dark matter, have caught initial glimpses of neutrinos born in the sun, physicists report.

“That’s
