This article considers the importance of “religion” and “identity” in the process of fieldwork in the North Cachar Hills, Assam, India. The political sensitivities in the region provided a difficult context in which to do fieldwork. This is chiefly because of the various armed insurrections, which have arisen as a consequence of the complicated remnants of British colonialism (1834–1947), and the subsequent post-independence challenge of nation building in India. This article raises important methodological questions concerning fieldwork and the relational grounding of the fieldworker relative to the inside/outside positions. It reflects on these issues by discussing the Heraka, a Zeme Naga religious movement. Their ambiguity and “in-between” character accommodates both the “neo-Hindu” version of a nation or Hindutva (Hinduness) and the larger Naga (primarily Christian) assertion of their own cultural and religious autonomy. The Heraka provides an alternative route into ideas of nationhood, religious belonging and cultural identity.

Nature has always inspired robotic designs and concepts. It is conceivable that biomimic nanorobots will soon play a prominent role in medicine. In this paper, we developed a natural killer cell-mimic AIE nanoterminator (NK@AIEdots) by coating natural kill cell membrane on the AIE-active polymeric endoskeleton, PBPTV, a highly bright NIR-II AIE-active conjugated polymer. Owning to the AIE and soft-matter characteristics of PBPTV, as-prepared nanoterminator maintained the superior NIR-II brightness (quantum yield ~8%) and good biocompatibility. Besides, they could serve as tight junctions (TJs) modulator to trigger an intracellular signaling cascade, causing TJs disruption and actin cytoskeleton reorganization to form intercellular “green channel” to help themselves crossing Blood-Brain Barriers (BBB) silently. Furthermore, they could initiatively accumulate to glioblastoma cells in the complex brain matrix for high-contrast and through-skull tumor imaging. The tumor growth was also greatly inhibited by these nanoterminator under the NIR light illumination. As far as we known, The QY of PBPTV is the highest among the existing NIR-II luminescent conjugated polymers. Besides, the NK-cell biomimetic nanorobots will open new avenue for BBB-crossing delivery.
