Refractive index modulation by ultraviolet absorption of canonical amino acids for in vivo optical transparency

26/08/2026 - The inherent opacity of most mammalian tissues limits deep-tissue optical imaging and light delivery. In contrast, the natural transparency of certain species and ocular tissues has been hypothesized...

Pruning the Search, Not the Signal: Adaptive-Banding Needleman-Wunsch via Protein Language Model Confidence

26/08/2026 - Dynamic programming yields exact quadratic-time (O(NM)) pairwise sequence alignments. Static banding heuristics (O(NW)) fail catastrophically on low-identity (below 30 percent), asymmetric...

A Conserved SIFamide Circuit Functions as the Insect Vagus Nerve

26/08/2026 - The insect functional homolog of the mammalian vagus nerve has remained elusive. Here, we identify the SIFamide (SIFa) peptidergic circuit as this homolog in Drosophila melanogaster. SIFa neurons...

Compressed representations underpin knowledge awareness in sequence learning

26/08/2026 - Humans can acquire sequence structure before its presence enters awareness, and in some learners this implicit knowledge later becomes accessible and reportable. Yet the neural reformatting that...
