Noninvasive Intelligent Brain‐Metasurface System for Real‐Time Electromagnetic Wave Manipulation

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
A noninvasive intelligent brain–computer interface (BCI) is integrated with a reconfigurable metasurface to establish a direct neural‐to electromagnetic transduction pathway for real time, multimodal wave control. By combining convolutional‐neural‐network‐based decoding of motor‐imagery electroencephalography (EEG) signals with threshold‐based ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

Arbuscular mycorrhizal fungal (AMF) communities in sand bars associated with Ipomoea pes‐caprae: a promising strategy for petroleum spill bioremediation in coastal dunes

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Polycyclic aromatic hydrocarbons (PAHs), a class of petroleum‐derived compounds known for causing cellular damage and for their recalcitrant behavior, severely limit effective biodegradation. Arbuscular mycorrhizal fungi (AMF) from oil‐contaminated environments can mitigate PAH‐related stress on host plants, highlighting the ...
