Physical reservoir computing (PRC) utilizing synaptic devices shows significant promise for edge AI. Researchers from the Tokyo University of Science have introduced a novel self-powered dye-sensitized solar cell-based device that mimics human synaptic behavior for efficient edge AI processing, inspired by the eye's afterimage phenomenon. The device has light intensity-controllable time constants, helping it achieve high performance during time-series data processing and motion recognition tasks. This work is a major step toward multiple time-scale PRC.

Does the global beauty trend have positive social aspects as well? A new study from Tel Aviv University shows that people who make an effort to improve their appearance—whether this effort is real or imagined, in the physical world or on social media—act more kindly towards others and are twice as likely to donate to charity.

Geneticists have studied the distribution of Y-chromosome haplogroups on the Faroe Islands, known to have been colonized by Vikings around the year 900 CE, and compared these to distributions of haplogroups in today’s Scandinavia. They showed with novel analysis methods that the haplotype distribution in the Faroe Islands most closely resembled that in Norway and Denmark, and to a lesser extent that in Sweden, but differed from that in Iceland. They concluded that a band of Viking men from all over Scandinavia colonized the Faroe Islands, which differed in their geographical origin and genetic make-up from those who settled Iceland.

Camera traps and drones deployed by government authorities to monitor a forest in India are infringing on the privacy and rights of local women.
