Researchers developed an all-optical memory array that uses near-infrared and visible light to strengthen or weaken its electronic conductance. In a 32 × 32 array, the system classified microscopic blood-cell images with 96.5% accuracy and showed reported resistance to noise.
In healthy adults, a subanesthetic dose of nitrous oxide changed how large brain networks were organized during a visual task. Weaker connections involving the insula, a region involved in integrating bodily and emotional signals, were associated with more unpleasant visual experiences.
Researchers have isolated the first cultivated virus known to infect a chrysophyte, an aquatic protist that can both photosynthesize and consume prey. Its genome contains a proteorhodopsin-like gene, a type of gene not previously reported in a virus, although predictions suggest the protein may not function as a light-driven proton pump.
