Efficient RNA extraction is critical for all downstream molecular applications and techniques. Despite the availability of several commercial kits, there is an enormous scope to develop novel materials that have high binding and elution capacities. Here we show that RNA from the cells can be extracted by dendritic fibrous nanosilica (DFNS) with higher efficiency than commercially available silica. This could be because of the unique fibrous morphology, high accessible surface area, and nano-size particles of DFNS. We studied various fundamental aspects, including the role of particle size, morphology, surface area, and charge on silica surface on RNA extraction efficiency. Infrared spectroscopy (FTIR) studies revealed the interaction of functional groups of the RNA with the silica surface, causing selective binding. Due to the sustainable synthesis protocol of DFNS, the simplicity of various buffers and washing solutions used, this RNA extraction kits can be assembled in any lab. In addition to the fundamental aspects of DFNS-RNA interactions, this study has the potential to initiate the development of indigenous DFNS based kits for RNA extraction.

A series of 12H-benzo[4'',5'']thieno[2'',3'':4',5']thieno[2',3':4,5]thieno[3,2-b]indoles was efficiently prepared in three step starting from available benzo[b]thieno[2,3-d]thiophen-3(2H)-ones. To this end, these fused ketones were treated with the Vilsmeier reagent and hydroxylamine hydrochloride, thus giving 3-chlorobenzo[b]thieno[2,3-d]thiophene-2-carbonitriles, which then reacted with methyl thioglycolate to form methyl 3-aminobenzo[4',5']thieno[2',3':4,5]thieno[3,2-b]thiophene-2-carboxylates in accordance with the Fiesselmann thiophene synthesis protocol. Finally, the desired N,S-heterohexacenes were obtained by the conversion of these fused 3-aminothiophene-2-carboxylates to the corresponding 3-aminothiohene intermediates, which play role of synthetic equivalents of thiophen-3(2H)-ones, followed by their acid-promoted reaction with arylhydrazines in accordance with the Fischer indolization reaction.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.
