How does the brain retain a sequence of events in memory? Researchers from the University Hospital Bonn (UKB), the University of Bonn, the University Hospital Tübingen and the University of Tübingen investigated this question. Using a unique measurement technique with implanted electrodes in the human brain, they were able to test a widely accepted theory of memory processes for the first time. The response pattern of the nerve cells did not align with the theory, but could be explained by a new model. The results have now been published in the journal "Nature Neuroscience".

In a paper published in National Science Review, a team of Chinese scientists develop an AI-powered framework designed to achieve real-time, seamless retrieval of PM₁₀ concentrations. This breakthrough addresses the challenges of spatial gaps and nighttime observation deficiencies in current satellite-based PM10 data. It extends daily data to high-resolution, real-time hourly insights, providing strong support for precise dust storm monitoring.

When wildfires threaten communities, human health can be impacted as smoke distributes on the breeze, infiltrating various structures. To help people protect themselves and their families, researchers have developed a low-cost, durable, do-it-yourself air filtration system that works as well as more expensive HEPA filters to clear indoor air pollutants such as smoke — or possibly limit the impact of airborne disease spread. They will present their results at the ACS Spring 2025 Digital Meeting.
