Inverse Seesaw, dark matter and the Hubble tension
We consider the inverse Seesaw scenario for neutrino masses with the approximate Lepton number symmetry broken dynamically by a scalar with Lepton number two.

Challenges of the Standard Cosmological Model
Measurements of the temperature and polarization anisotropy of the cosmic microwave background (CMB) provided strong confirmation of the vanilla flat ΛCDM model of structure formation.

Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

Hubble tension and absolute constraints on the local Hubble parameter
It is shown, from the two independent approaches of McCrea-Milne and of Zeldovich, that one can fully recover the set equations corresponding to the relativistic equations of the expanding universe of Friedmann-Lemaitre-Robertson-Walker geometry ...

A theoretical explanation for the so-called Hubble tension is provided within the framework of phase-space quantum mechanics extended to (quantum) cosmology.

Abstract In this work we investigate how ionization from Galactic Cosmic Rays (GCRs) can affect aerosol nucleation on Neptune and discuss potential implications for the observed brightness variations that appear to follow the solar cycle. We calculate the planetary vertical cutoff rigidity for Neptune based on the O8 ${\mathrm{O}}_{8}$ magnetic field ...

Cosmological implications of ns ≈ 1 in light of the Hubble tension
Recently, a low-z measurement of the Hubble constant, H0=73.04±1.04km/s/Mpc, was reported by the SH0ES Team. The long-standing Hubble tension, i.e. the difference between the Hubble constant from the local measurements and that inferred from the cosmic ...

ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

ABSTRACT Background It is well‐established that earlier generations of lipid emulsions based on soybean oil are inferior to later generations based on olive or fish oil. However, evidence directly comparing between later‐generation lipid emulsions is limited.

Korean red Ginseng significantly reduces tremor severity, improves motor coordination, and ameliorates anxiety and cognitive deficits in a mouse model of essential tremor through suppression of neuroinflammatory markers and normalization of neuroplasticity genes in the cerebellum.
