Prediscovery Activity of New Interstellar Object 3I/ATLAS: Rapid Brightening from 6 to 4 au

The Astrophysical Journal Letters
We 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 ...

Pediatric Cervicofacial Necrotizing Fasciitis: A Case Report Highlighting the Diagnostic Challenges and Management in a Child Without Preceding Trauma or Infection

Clinical Case Reports, Volume 13, Issue 12, December 2025.
ABSTRACT Necrotizing fasciitis (NF) is a rare but serious life‐threatening condition in children that can be easily overlooked due to its atypical presentation and absence of common risk factors. This case involves a 10‐year‐old girl with a history of non‐transfusion‐dependent thalassemia and epilepsy who developed cervicofacial NF without any prior ...

Modeling the effects of a faint dust coma on asteroid spectra [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractIn this work we use a simple model to study the influence of a faint dust coma on asteroid spectra, in an effort to reproduce the unusual spectral behavior seen on the asteroid (5201) Ferraz-Mello and other objects.

The First Detection of Molecular Activity in the Largest Known Oort Cloud Comet: ALMA Imaging of C/2014 UN271 (Bernardinelli–Bernstein) at 16.6 au from the Sun

The Astrophysical Journal Letters
We report observations of comet C/2014 UN271 (Bernardinelli–Bernstein) carried out on UT 2024 March 8 and 17 at a heliocentric distance ( r _H ) of 16.6 au using the Atacama Large Millimeter/submillimeter Array (ALMA).

Intrahepatic Cholangiocarcinoma Masquerading as Liver Abscess: A Case Report With Multimodal Imaging

Clinical Case Reports, Volume 13, Issue 12, December 2025.
ABSTRACT The presentation of intrahepatic cholangiocarcinoma (ICC) often masquerades as a pyogenic liver abscess. Therefore, atypical imaging features on multimodal studies, together with markedly elevated levels of Gamma‐glutamyl Transpeptidase (GGT), Alkaline Phosphatase (ALP) and Carbohydrate antigen 19‐9 (CA19‐9), must alert clinicians to the ...

Microbiota and Quality Indexes of Commercial Sauerkraut and Fermented Cucumbers

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Secundilactobacillus and Levilactobacillus were found to be significantly correlated with the content of cadaverine and histamine in the sauerkraut and fermented cucumbers. The high level of biogenic amines in the tested market samples indicates the need to monitor them as an indicator of the hygienic condition of fermented products.

Infrared emission from dust in the Coma cluster of galaxies

The Astrophysical Journal, 1990
Detailed calculations of the infrared emission from collisionally heated dust in the Coma cluster are presented. The proposed model includes continuous dust injection from galaxies, grain destruction by sputtering, and transient grain heating by the hot plasma.

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 ...

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, Volume 103, Issue 12, Page 781-889, December 2025.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Boulder Migration in the Khonsu Region of Comet 67P/Churyumov–Gerasimenko

The Astrophysical Journal
The European Space Agency's Rosetta mission is the only space mission that has performed long-term monitoring of a comet at close distances. For over two years, Rosetta rendezvoused with comet 67P/Churyumov–Gerasimenko, which revealed diverse ...
