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 ...

Impact of Seasonal Composition on the Long‐Term Performance of Post‐Consumer Recycled Polypropylene
Journal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.Ten batches of post‐consumer polypropylene recyclate were examined over a period of 15 months. Despite identical MFR and density specifications, there were significant differences in their composition, affecting mechanical performance. Elongation at break and crack resistance varied particularly strongly.

A Dormant Captured Oort Cloud Comet Awakens: (18916) 2000 OG44
The Astrophysical Journal LettersWe report the discovery of activity emanating from (18916) 2000 OG _44 (alternately designated 1977 SD), a minor planet previously reported to be both an extinct comet and an asteroid on a cometary orbit. We observed 2000 OG _44 with a thin tail oriented

Health Science Reports, Volume 9, Issue 3, March 2026.ABSTRACT Background and Aims The present review aims to ascertain whether reproductive disorders are associated with specific physical, mental, personality, and social traits. This information may be used to support or reject the hypothesis on the origin of infecundity, which proposes that women/men with preferred characteristics, including high ...

Prediscovery Activity of New Interstellar Object 3I/ATLAS: Rapid Brightening from 6 to 4 au
The Astrophysical Journal LettersWe report on the prediscovery observations and constraints of the new interstellar comet 3I/2025 N1 (ATLAS), made by the Zwicky Transient Facility, for the inbound leg of the comet out to a heliocentric distance of r _h = 17 au, or approximately a year ...

Journal of Biomedical Materials Research Part A, Volume 114, Issue 3, March 2026.Illustration of bacteria translocating into the lumen of the vasculature through tissue and through a hydrogel matrix. We hypothesized that one was more challenging than the other. We found that while proliferation and penetration depth were similar, breakthrough from hydrogel matricies was higher.

Influence of Competitive C–P Segregation on Austenite Grain Growth in Iron Alloys
steel research international, Volume 97, Issue 3, Page 1432-1443, March 2026.This study investigates how carbon influences phosphorus‐induced solute drag effects during isothermal annealing of austenite grain growth in Fe–C–P alloys. Using in situ high‐temperature laser scanning confocal microscopy and density functional theory simulations, it demonstrates that carbon above a critical temperature significantly reduces P ...
