Studying the Earth’s Interior with (atmospheric) Neutrinos
Astrophysicists and their experiments normally look up, not down. IceCube is an exception. Here the density profile of the Earth is measured using neutrinos.

The loudest planets in our sky: gravitational waves from Super-Jupiters
Nearby Super-Jupiters with very tight orbits produce gravitational waves that will be detectable by space-based gravitational wave detectors.

Multi-messenger observations of a flaring blazar coincident with an IceCube neutrino
The first compelling association of an electromagnetic counterpart with an astrophysical neutrino since SN 1987A.

Probing the source of a mysterious (dark matter?) line in the laboratory
A laboratory astrophysics experiment calls into question the proposed dark matter origin of an unidentified spectral line at 3.5 keV
