Electrotactile stimulus is a form of sensory substitution in which an electrical signal is perceived as a mechanical sensation. The electrotactile effect could, in principle, recapitulate a range of tactile experience by selective activation of nerve endings. However, the method has been plagued by inconsistency, galvanic reactions, pain and desensitization, and unwanted stimulation of nontactile nerves.

However, current computational methods for understanding the rigidity of polymer chains fail in one crucial way. Namely, standard torsional scan (TS) methods do not satisfactorily capture the behavior of polymers exhibiting a high degree of steric hindrance.

Article Synopsis
- Preventing spontaneous crystallization in supersaturated solutions is essential for industries like chemical, pharmaceutical, and food, but challenges persist in both lab and real-world applications.
- The study examines how antifreeze proteins (AFPs) can hinder crystallization, focusing on D-mannitol, a sugar alcohol, and showing that insect AFP DAFP1 can completely stop its nucleation.
- Findings reveal that AFPs work by binding to crystal-forming molecules and altering their behavior in solution, suggesting that natural polymers could be key in developing new methods to control crystallization processes.
