Analysing Resilience Indicator Traits in Austrian Fleckvieh, Brown Swiss and Holstein‐Friesian Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Recent studies suggest that variations in milk yield during lactation can serve as a metric for assessing individual resilience, with minimum fluctuations reflecting greater resilience in cows. With automatic milking systems, multiple records can be obtained from many cows on a daily basis. Given that animals are continually exposed to a range

Down But Not Out: The Case of Long-period Comet C/2021 O3 (Panstarrs)

The Astronomical Journal
We combine ground- and space-based observations of long-period comet C/2021 O3 (Panstarrs; perihelion distance 0.287 au) in order to investigate its reported near-perihelion destruction.

The PagDMG6341–PagWD40–PagPOLD4 Module Coordinates Base Excision Repair in ‘84K’ Poplar (Populus alba × P. glandulosa)

Plant Biotechnology Journal, EarlyView.
ABSTRACT Base excision repair (BER) is a critical pathway for repairing damaged DNA bases in cells; however, the mechanisms of protein recruitment and interaction in this pathway remain largely unexplored in higher plants. In this study, we used ‘84K’ poplar (Populus alba × P.

A Multiwavelength Study of Comet C/2022 E3 (ZTF): Complementary ALMA and JWST Investigations of Water and Methanol in Cometary Comae

The Astronomical Journal
Long-period comets, which are often considered to be representative of material in the protoplanetary disk that formed the solar system, are ideal to investigate the question of chemical inheritance in astronomy. Determining the chemistry of comets, both

Harnessing blue light photobiomodulation for cancer therapy: Evidence from a systematic review

Photochemistry and Photobiology, EarlyView.
Conventional treatments for various types of cancer are often associated with tumor recurrence and aggressiveness. Photobiomodulation with blue light (BL; 450–470 nm) emerges as a promising alternative with antitumor effects. This systematic review, with 37 in vitro and in vivo studies from 2002 to 2024, revealed that BL reduces cell viability ...

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

Photochemistry and Photobiology, EarlyView.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.

Activity of Halley-type Comets 12P/Pons–Brooks and 13P/Olbers from SOHO/SWAN Observations

The Planetary Science Journal
The Solar Wind ANisotropies (SWAN) all-sky hydrogen Ly α camera on the Solar and Heliosphere Observatory (SOHO) observed the hydrogen coma of Halley-type comet (HTC) 12P/Pons–Brooks from SOHO’s halo orbit around L1 throughout its 2023–2024 apparition ...

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

Photochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

JWST Detection of a Carbon-dioxide-dominated Gas Coma Surrounding Interstellar Object 3I/ATLAS

The Astrophysical Journal Letters
3I/ATLAS is the third confirmed interstellar object to visit our solar system and only the second to display a clear coma. Infrared spectroscopy with the James Webb Space Telescope (JWST) provides the opportunity to measure its coma composition and ...

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.
