Comparative Evaluation of Genotoxicity of Captan in Amphibian Larvae (Xenopus laevis and Pleurodeles waltl) Using the Comet Assay and the Micronucleus Test [PDF]

open access: yes, 2006
Captan (N-trichloromethylthio-4-cyclohexene-1,2-dicarboximide) is a fungicide used to inhibit the growth of many types of fungi on plants used as foodstuffs.

Muon-to-electron conversion in mirror fermion model with electroweak scale non-sterile right-handed neutrinos

open access: yesNuclear Physics B, 2018
The muon-to-electron conversion in aluminum, titanium and gold nuclei is studied in the context of a class of mirror fermion model with non-sterile right-handed neutrinos having masses at the electroweak scale.

Diagnosis and surgical treatment of cutaneous neurofibroma in a goldfish (Carassius auratus)

open access: yesVeterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract A goldfish (Carassius auratus) from a pet store was presented with a nodular lesion on the dorsal cranial region. The fish exhibited normal swimming behaviour and appetite. Clinical evaluation, haematology analysis, and radiography confirmed a superficial cutaneous mass without internal organ involvement.

Reversal of Spin: Comet 41P/Tuttle–Giacobini–Kresak

open access: yesThe Astronomical Journal
The rotations of cometary nuclei are known to change in response to outgassing torques. The nucleus of the Jupiter-family comet 41P/Tuttle–Giacobini–Kresak exhibited particularly dramatic rotational changes when near perihelion in 2017 April.

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

open access: yesChemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Quantifying the Effects of Nickel on Earth’s Inner‐Core Nucleation

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The formation of Earth’s solid inner core marks a major transition in the thermal and chemical evolution of the deep Earth, yet its origin remains paradoxical, as initial nucleation appears to require unrealistically large undercooling in the outer core.

Chaotic dynamics around cometary nuclei

open access: yes, 2018
International audienceWe apply a generalized Kepler map theory to describe the qualitative chaotic dynamics around cometary nuclei, based on accessible observational data for five comets whose nuclei are well-documented to resemble dumb-bells.

Lignin Mimicking Protein Methylation Augments the Efficacy of FOLFOX Chemotherapy by Anchoring Thymidylate Synthase

open access: yesAdvanced Materials, Volume 38, Issue 57, 13 October 2026.
Lignin‐mimicking protein methylation can enhance the efficacy and mitigate the toxicity of the classic FOLFOX chemotherapy regimen. ABSTRACT FOLFOX has served as the standard chemotherapy regimen for advanced stages, specifically in the treatment of pancreatic, colorectal, and bladder cancers.

The crash of P/Shoemaker-Levy 9 into Jupiter and its implications for comet bombardment on Earth [PDF]

open access: yes, 1994
Periodic Comet Shoemaker/Levy 9 will impact Jupiter in late July 1994. The comet, which broke into more than 20 telescopically detectable fragments when it passed with the Roche lobe of Jupiter on July 8, 1992, is captured in a highly eccentric orbit ...
