Neutrinos Carry the Hidden Energy of Core-Collapse Supernovae

Core-collapse supernovae emit the vast majority of their energy as neutrinos rather than light—about 99% versus 0.1–1% in photons—because electron capture in the collapsing core produces neutrinos that escape with little interaction. This neutrino burst powers the explosion and confirms the energy budget, as demonstrated by SN 1987A's detections; with detectors like Hyper-Kamiokande and IceCube, a future galactic SN would yield millions of neutrinos, making neutrinos the primary energy carrier in these events.

Experimental Confirmation of Atomic Decay Pathway Enhances Nuclear Periodic Table

A research team from the University of Cologne has experimentally confirmed the electron capture decay of technetium-98, a process previously only theorized, by detecting rare decay events using advanced shielding and measurement techniques, thereby enriching the understanding of nuclear decay pathways and updating the nuclear periodic table.

"Heating Up the Race to Weigh the Mysterious Neutrino"

Physicists are racing to weigh neutrinos, the mysterious elementary particles, with the KATRIN detector in Germany currently leading the effort. Alternative approaches are being developed at various laboratories, with the goal of building scaled-up versions to compete with or improve upon KATRIN. These efforts are driven by the need to measure the tiny masses of neutrinos, which could potentially challenge current estimates from cosmology. Techniques such as electron capture and the Project 8 experiment are being explored to achieve greater sensitivity in neutrino mass measurements.
