Superheavy gravitinos and ultra-high energy cosmic rays [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2019
We argue that the superheavy gravitinos that we had previously proposed as candidates for Dark Matter can offer a possible explanation for the ultra-high energy cosmic ray (UHECR) events observed at the Pierre Auger Observatory, via gravitino anti-gravitino annihilation in the `skin' of neutron stars.

Natural‐based antioxidants in cosmeceuticals: Extraction, bioavailability and skin ageing applications

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Natural antioxidants from plants, fruits, seeds and fungi combat ageing by neutralizing free radicals, boosting collagen and protecting against UV damage. Enhanced by green extraction and smart delivery systems, they offer powerful anti‐inflammatory and antimicrobial benefits.

Palamism Does Not Disfigure the Gospel: A Reply to Thomas Weinandy

open access: yesInternational Journal of Systematic Theology, EarlyView.
Abstract In a 2024 article in the IJST, Fr. Thomas Weinandy argues that the theological system of Gregory Palamas is in grave error, especially with respect to its commitment to an objective ontological distinction between God's essence and His energies. In his concluding paragraph Fr.

Air Shower Detection by Arrays of Radio Antennas [PDF]

open access: yesEPJ Web of Conferences, 2019
Antenna arrays are beginning to make important contributions to high energy astroparticle physics supported by recent progress in the radio technique for air showers. This article provides an update to my more extensive review published in Prog.

Epidemiology and Genetics of Rheumatic Diseases Suggest a Constant Rate of DNA Damage as Underlying Cause

open access: yesImmunology, EarlyView.
A constant rate of DNA damage that is not perfectly repaired will cause a constant rate of DNA mutations. The chance of mutation will increase if DNA is prone to damage, such as occurs in somatic hypermutation (SHM) hotspots and GC‐rich DNA. Thus, if one mutation‐prone DNA site drives disease, the age of onset of disease and degree of penetrance should

On the Potential Cosmogenic Origin of the Ultra-high-energy Event KM3-230213A

open access: yesThe Astrophysical Journal Letters
On 2023 February 13, the KM3NeT/ARCA telescope observed a track-like event compatible with a ultra-high-energy muon with an estimated energy of 120 PeV, produced by a neutrino with an even higher energy, making it the most energetic neutrino event ever ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
