Reactive Oxygen Species‐Induced Damage in Cryopreserved Bovine Sperm: Mitigation Strategies

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Cryopreservation of bovine sperm results in overproduction of ROS due to osmotic pressure variations, ice crystals and dysfunction of mitochondria, which causes lipid peroxidation, fragmentation of DNA, protein damage and ultimately decline of post‐thaw sperm quality.

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

open access: yesBrain Pathology, Volume 36, Issue 4, July 2026.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...

The Feeding Ecology of Invasive Pink Salmon Juveniles in Northern Norwegian Rivers and Their Role as Prey to Native Salmonids

open access: yesEcology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Increasing numbers of invasive Pacific pink salmon (Oncorhynchus gorbuscha) are spawning in northern Norwegian rivers, leading to large numbers of juveniles migrating to coastal waters. This raises concerns about food competition with native salmonids in rivers, although details about the timing and intensity of pink salmon feeding and the ...

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

open access: yesEquine Veterinary Journal, Volume 58, Issue 4, Page 970-980, July 2026.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Reduced Mechanical Tactile Stimulation Under Space Microgravity Affects Synaptic Signaling and Contributes to Neuromuscular Aging in Caenorhabditis elegans

open access: yesThe FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Microgravity (μG) reduces mechanical tactile stimulation in Caenorhabditis elegans, causing neuromuscular decline, altered gene expression, synaptic defects, and accelerated aging phenotypes. The gentle‐touch mechanoreceptor MEC‐4 mediates μG‐induced body length reduction and extracellular matrix gene downregulation.
