In a paper published in National Science Review, a team from Tsinghua University analyzed the diffusion process of the treated Fukushima accident contaminated water to be discharged into the Pacific Ocean from 2023. Results show that the tritium, the main pollutant in the radioactive water, will spread to the whole North Pacific in 1200 days, which is important to formulate global coping strategies.

An international business–academia collaboration has yielded a new type of projector that can project RGB and invisible infrared images simultaneously and independently at a high speed of almost 1,000 fps. With its high image alignment accuracy enabled by a custom optics engine, this projector will help closely integrate invisible sensing and visible display for a wide range of novel applications, such as dynamic projection mapping.

Researchers from Osaka University and Kanazawa University have found that the physical texture of robots influenced perceptions of robot personality. Furthermore, first impressions of robots, based on physical appearance alone, could influence the relationship between physical texture and robot personality formation. This work could facilitate the development of robots with perceived personalities that match user expectations.

During pandemic-induced isolation, researchers from the University of Minnesota surveyed older adults with vision loss, with hearing loss, or without either condition, asking the participants about their worries, well-being, and social isolation at six-week intervals. All three groups scored lower on a patient health questionnaire after the pandemic began; however, people with vision or hearing loss faced unique problems in lockdown. Disruptions to mobility systems affected people with low vision, and masks made conversations especially difficult for adults with hearing loss.

Scientists with the University of Chicago have published an analysis laying out how the tiny beads of glass inside many meteorites came to be—and what they can tell us about what happened in the early solar system.

Ocean predators cannot survive on average concentrations of food found in the water. Instead, they survive by exploiting small patches of food-rich areas peppered throughout the world's waterways. Using active acoustics, researchers found the ocean is widely populated with narrow hotspots of activity. Traditionally, these hotspots are missed with conventional sampling tools, but locating them can provide dynamic layered maps of ocean life. The findings signify ocean food and biota as patchy, varying with depth and location, suggesting animals must find and exploit small-scale aggregations of resources.
