December 12, 2024• Physics 17, 175Astrophysicist and science communicator Neil deGrasse Tyson shares some thoughts on why and how scientists should communicate. ×Few physicists are as familiar to the general public as Neil deGrasse Tyson, the astronomer and science communicator who directs the Hayden Planetarium at the American Museum of Natural History in New York City. He has popularized science through books, radio talk shows, documentaries, and many other media appearances.

November 7, 2024• Physics 17, 161Two dark matter searches report that their detectors have likely recorded neutrinos coming from the Sun—spotting the “neutrino fog” that could imperil future dark matter searches. ×Several leading searches for dark matter operate in some of the deepest underground laboratories in the world, screened from cosmic rays and other backgrounds that could obfuscate a dark matter signal.

June 6, 2024• Physics 17, s69Some ultralight black holes that formed soon after the big bang might have been exotic objects with a net “color charge” that left potentially observable signatures. ×Primordial black holes (PBHs)—hypothetical objects formed by the gravitational collapse of dense regions in the early Universe—have been invoked as dark-matter candidates. But for PBHs to constitute all dark matter, they’d have to be extremely light, possibly weighing less than small asteroids.

May 23, 2024• Physics 17, s62Spacetime wrinkles known as cosmic strings, which might have formed in the early Universe, could be a dominant source of gravitational waves at ultrahigh frequencies, according to new calculations. ×Existing and planned gravitational-wave detectors, from pulsar timing arrays to laser interferometers, probe signal frequencies up to several kilohertz.

April 18, 2024• Physics 17, s47Dense ensembles of laser-cooled molecules allow the observation of molecular collisions—a result that could lead to applications of cold molecular gases in quantum simulation and fundamental physics tests. Ultracold molecules are promising platforms for quantum simulation and for precision tests of fundamental physics.
