A universe without dark matter

INTRO: The standard cosmological model, critics argue, is built on unobserved phenomena like dark matter, but is defended by the mainstream despite mounting contradictions. However, physicist Martín López-Corredoira argues that there is no elusive dark matter particle waiting to be found that would explain the Big Bang. Instead, we may need a patchwork of explanations: modified gravity, baryonic matter, and contextual fixes. It’s time to abandon the search for a one-size-fits-all cosmic theory... (MORE - details)
A fifth force of nature may have been discovered inside atoms

EXCERPT: A Yukawa particle is the hypothesized mediator of a possible force within the cores of atoms. If it exists, it would have a subtle influence on how particles making up an atom's nucleus interact with each other, and possibly how they interact with electrons.
Unlike recent attempts to tease out the force's predicted effects on a cosmic scale, physicists behind this latest investigation turned their focus to a far smaller space in the orbitals around the nuclei of four different kinds of calcium.
[...] Whatever that ambiguity may be in their calculations, the researchers demonstrated it was largely down to a single factor – which could be a clue towards the existence of a fifth force.
It would take further experimentation and improved calculations to confirm whether any dynamics within their resulting deviations was the result of known physics or the hypothesized Yukawa interaction, but researchers now have a better idea of what to look for at least.
This research was published in Physical Review Letters... (MORE - missing details)
