Like a fussy chef, dark matter can only 'cook' the Universe using certain particles. New work shows how strongly it prefers quarks (the building blocks of atomic nuclei) over leptons (electrons and their kin). Using the idea of culinary symmetries and their violations, scientists estimated how far o

Recently, pulsar timing array collaborations detected a stochastic background of nanohertz gravitational waves. Scientists investigated whether a first-order phase transition in the simplest dark sector — an Abelian Higgs model — could have produced it. Precision thermodynamic analysis using dimensi
