Possibility of formation of motor defensive dominant (by serial electrical stimulation) at the background of active blinking dominant was studied in chronic behavioral experiments in rabbits. Formation of motor defensive dominant under such conditions was a problem. When the active dominant focus was inhibited and symmetrical representation of the other eye was activated formation of motor defensive dominant was also problematic. Stable coexistence of the two dominants was not observed under conditions when one of them was formed at the background of the other.

For similar species to co-occur in places where resources are limited, they need to adopt strategies that partition resources to reduce competition. Our understanding of the mechanisms behind resource partitioning among sympatric marine predators is evolving, but we lack a clear understanding of how environmental change is impacting these dynamics. We investigated spatial and trophic resource partitioning among three sympatric seabirds with contrasting biological characteristics: greater crested terns Thalasseus bergii (efficient flyer, limited diver, and preference for high quality forage fish), little penguins Eudyptula minor (flightless, efficient diver, and preference for high quality forage fish) and silver gulls Chroicocephalus novaehollandiae (efficient flyer, limited diver and generalist diet).

Autosomal dominant mutations in the gene encoding the DNA and RNA binding protein FUS are a cause of amyotrophic lateral sclerosis (ALS), and about 0·3-0·9% of patients with ALS are FUS mutation carriers. FUS-mutation-associated ALS (FUS-ALS) is characterised by early onset and rapid progression, compared with other forms of ALS. However, different pathogenic mutations in FUS can result in markedly different age at symptom onset and rate of disease progression.

Oxidative stress is a significant factor in the death of granulosa cells (GCs), leading to follicular atresia and consequently limiting the number of dominant follicles that can mature and ovulate within each follicular wave. Follicular fluid contains a diverse array of metabolites that play crucial roles in regulating GCs' proliferation and oocyte maturation, which are essential for follicle development and female fertility. However, the mechanisms behind metabolite heterogeneity and its effects on GCs' function remain poorly understood.

Prioritizing defense over growth often occurs under ultraviolet (UV)-B radiation while several studies showed its growth-promoting effects on photosynthetic organisms, how they overcome the growth-defense trade-off is unclear. This study deciphered the acclimation responses of the cyanobacterium Nostoc sphaeroides to low UV-B radiation (0.08 W m) using quantitative proteomic, physiological and biochemical analyses.

Arid desert regions are among the harshest ecological environments on Earth. Halophytes, with their unique physiological characteristics and adaptability, have become the dominant vegetation in these areas. Currently, research on halophytes in this region is relatively limited, particularly concerning studies related to their root endophytic fungi, which have been rarely reported on.
