Article Synopsis
- Pathological mutations in the Trk-fused gene (TFG) are linked to neurodegenerative diseases, particularly hereditary spastic paraplegia (HSP), causing lower limb issues.* -
- Researchers used X-ray crystallography and cryo-electron microscopy to reveal how TFG forms octameric ring complexes, crucial for its function.* -
- Mutations from HSP patients disrupt the stability of these complexes, leading to neurodegenerative effects, but different mutations have varying impacts, indicating multiple mechanisms of disease progression.*
Applications of photoluminescence (PL) from semiconductor quantum dots (QDs) have faced the dichotomy of excitonic emission being susceptible to self-absorption and shallow defects reducing quantum yield (QY) catastrophically, and doped emissions sacrificing the tunability of the emission wavelength a quantum size effect, making it extremely challenging, if not impossible, to optimize all desirable properties simultaneously. Here we report a strategy that simultaneously optimizes all desirable PL properties in CdS QDs by leveraging interface engineering through the growth of two crystallographic phases, namely wurtzite and zinc blende phases, within individual QDs. These engineered interfaces result in sub-bandgap emissions ultrafast energy transfer (∼780 fs) from band-edge states to interface states protected from surface defects, enhancing stability and prolonging the PL lifetime.

- - The study investigates the fertile properties of termite mound soil compared to other common potting media by examining seven different soil combinations for their physical, chemical, and biological qualities.
- - After laboratory analysis, the best potting mixtures were identified based on their nutrient content and enzyme activities, with one combination showing high levels of pH, organic carbon, nitrogen, phosphorus, potassium, and various enzyme activities.
- - The effectiveness of the selected mixtures was tested by growing the cv. Inca Orange crop, with one mixture showing superior growth indicators such as plant spread, leaf area index, and fresh weight.
Background: Literacy is an important factor that predicts cognitive performance. Existing cognitive screening tools are validated only in educated populations and are not appropriate for older adults with little or no education leading to poor performance on these tests and eventually leading to misdiagnosis. This challenge for clinicians necessitates a screening tool suitable for illiterate or low-literate older individuals.
