Seasonal Prevalence, Molecular Identification and Therapeutic Management of Enterotoxemia Caused by Clostridium perfringens Type D in Goats of Peshawar and Charsadda Districts, Pakistan

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Seasonal enterotoxaemia outbreaks in goats from the Peshawar and Charsadda districts were investigated through large‐scale faecal sampling, bacterial isolation, PCR‐based molecular confirmation of the etx gene, antimicrobial susceptibility testing and clinico‐therapeutic trials. The study demonstrates higher disease prevalence during spring and winter,

COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z < 4

The Astrophysical Journal
We study of the role of galaxy–galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with robust total star formation rate measurements from Herschel, gas masses ...

An Explanation for the Overrepresentation of Tidal Disruption Events in Post-starburst Galaxies

The Astrophysical Journal, 2023
Tidal disruption events (TDEs) provide a valuable probe for studying the dynamics of stars in the nuclear environments of galaxies. Recent observations show that TDEs are strongly overrepresented in post-starburst or “green valley” galaxies, although the

Genomic Insights Into Antimicrobial Resistance and Virulence of Enterococcus avium Strains From Bovine Mastitis in Some Selected Dairy Farms of Bangladesh

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
The graphical abstract outlines that samples from milk, faeces and soil were tested for Enterococcus avium using culture, PCR and genome sequencing.2. Overall, prevalence of E. avium was 56.3%, and 93.5% of isolates were multidrug‐resistant.3. Genomic analysis revealed six ARGs, 43–45 VFGs and 4–6 bacteriocins.4.

Dynamics of Cosmic Neutrinos in Galaxies

Open Astronomy, 2014
The cosmic background of massive (about 1 eV rest-energy) neutrinos can be cooled to extremely low temperatures, reaching almost completely degenerated state. The Fermi velocity of the neutrinos becomes less than 100 km/s.

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1593-1609, July 2026.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Formation of Galactic Disks. I. Why Did the Milky Way’s Disk Form Unusually Early?

The Astrophysical Journal
Recent results from spectroscopic and astrometric surveys of nearby stars suggest that the stellar disk of our Milky Way (MW) was formed quite early, within the first few billion years of its evolution.

Multi‐Dielectric Metasurfaces for Ultrabright, Tunable Structural Color and Reconfigurable Optical Filtering with Extraordinarily Large Color Span

Advanced Optical Materials, Volume 14, Issue 23, 19 June 2026.
Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.

Stellar CoRGI in MaNGA: Stellar Counterrotating Galaxies Identified in the MaNGA Survey

The Astrophysical Journal Supplement Series
Stellar counterrotating (CR) galaxies are systems hosting two large-scale stellar components rotating in opposite directions—a main, preexisting galaxy body with an older stellar population and a younger CR stellar disk likely formed from externally ...

Tracing the dynamical and structural complexity of spiral galaxy centres

Astronomy & Astrophysics
Context. The formation and evolution of late-type galaxies have traditionally been described in terms of two pathways, one producing pressure-supported classical bulges and the other producing rotationally supported pseudo-bulges.
