Primordial black holes from fifth forces
, 2018 Primordial black holes can be produced by a long range attractive fifth force stronger than gravity, mediated by a light scalar field interacting with nonrelativistic "heavy" particles.

Primordial black hole evolution in tensor-scalar cosmology [PDF]
, 1999 A perturbative analysis shows that black holes do not remember the value of the scalar field $\phi$ at the time they formed if $\phi$ changes in tensor-scalar cosmology.

Fast and Slow Signal Propagation in Abiotic Polypeptide Assemblies
ChemBioChem, Volume 27, Issue 6, 27 March 2026.Proteinoid microspheres formed by thermal polymerization of amino acids exhibit spontaneous electrical potential fluctuations without genetic material, membranes, or ion channels. Multi‐electrode recordings and electron microscopy reveal composition‐dependent voltage oscillations, long‐term drifts, and correlated signals across electrodes.

Structure of the Baryon Halo Around a Supermassive Primordial Black Hole
ParticlesAccording to some theoretical models, primordial black holes with masses of more than 108 solar masses could be born in the early universe, and their possible observational manifestations have been investigated in a number of works. Dense dark matter and

Enhanced detectability of spinning primordial black holes
European Physical Journal C: Particles and Fields, 2020 Primordial black holes which are produced during an epoch of matter domination are expected to spin rapidly. It is shown that this leads to an enhancement of the detectability of the stochastic gravitational-wave background from their mergers.

Antimatter from primordial black holes [PDF]
, 2002 Antiprotons and antideuterons are considered as probes to look for primordial black holes in our Galaxy. I give a brief overview of the latest developments on the subject.Comment: proceedings of the XIVth Rencontres de Blois : Matter-Antimatter ...

Number Counts and Non-Gaussianity [PDF]
, 2013 We describe a general procedure for using number counts of any object to constrain the probability distribution of the primordial fluctuations, allowing for generic weak non-Gaussianity.

Ecological Applications, Volume 36, Issue 2, March 2026.Abstract European forests are increasingly managed to harmonize production goals with biodiversity conservation, through practices such as retention and close‐to‐nature forestry. Forest birds may benefit from these practices, but it remains unclear how the effects of different management practices compare, and whether responses to management are driven
