Gyrate atrophy of the choroid and retina (GACR, OMIM #258870) is a rare inherited metabolic disorder characterized by progressive chorioretinal degeneration and hyperornithinemia. Current therapeutic modalities potentially slow disease progression but are not successful in preventing blindness. To allow for trial development, increased knowledge of the clinical phenotype and current therapeutic outcomes is required.

Article Synopsis
  • Excitons, which are pairs of electrons and holes held together by Coulomb forces, can form a superfluid at low temperatures due to their bosonic properties.
  • The research involves directly imaging this exciton superfluid in a specific material setup (MoSe-WSe heterostructure), demonstrating a significant level of order across the sample.
  • The study also details how variations in exciton density and temperature help construct a phase diagram, revealing that the superfluid state can persist up to 15 K, aligning well with theoretical expectations and paving the way for advancements in quantum devices and superfluid research.

Retinitis pigmentosa (RP) is a progressive inherited retinal dystrophy, characterized by the degeneration of photoreceptors, presenting as a rod-cone dystrophy. Approximately 20-30% of patients with RP also exhibit extra-ocular manifestations in the context of a syndrome. This manuscript discusses the broad spectrum of syndromes associated with RP, pathogenic mechanisms, clinical manifestations, differential diagnoses, clinical management approaches, and future perspectives.

While biological invasions continue to threaten biodiversity, most of current assessments focus on the sole exposure to invasive alien species (IAS), without considering native species' response to the threat. Here, we address this gap by assessing vertebrates' vulnerability to biological invasions, combining measures of both (i) exposure to 304 identified IAS and (ii) realized sensitivity of 1600 native vertebrates to this threat. We used the IUCN Red List of Threatened Species to identify species threatened by IAS, their distribution, and the species' range characteristics of their associated IAS.

Rachel Carson's warning of a silent spring directed attention to unwanted side effects of pesticide application. Though her work led to policies restricting insecticide use, various insecticides currently in use affect nontarget organisms and may contribute to population declines. The insecticide tebufenozide is used to control defoliating Lepidoptera in oak forests harboring rich insect faunas.
