Biomimetic Contact Behavior Inspired Tactile Sensing Array with Programmable Microdomes Pattern by Scalable and Consistent Fabrication.

Flexible sensor arrays have attracted extensive attention in human-computer interaction. However, realizing high-performance sensor units with programmable properties, and expanding them to multi-pixel flexible arrays to maintain high sensing consistency is still struggling. Inspired by the contact behavior of octopus antenna, this paper proposes a programmable multistage dome structure-based flexible sensing array with robust sensing stability and high array consistency.

Direct visualization of horizontal gene transfer in cotton plants.

Plant mitochondrial and chloroplast genes that underwent horizontal transfer have been identified by parasite and grafting systems, respectively. Here, we directly observed 3 horizontal gene transfer (HGT) events in the 45 second axillary shoots of grafted cotton plants (Gossypium barbadense and Gossypium hirsutum) after extirpating the first axillary bud. The second axillary shoots showed phenotypic variations in cotton flowers and seeds that were evidence of spontaneous development from cells in the grafting site.
