An emerging form of surveillance, “wireless-tapping,” explores the possibility of remotely deciphering conversations from the tiny vibrations produced by a cellphone’s earpiece. With the goal of protecting users’ privacy from potential bad actors, a team of computer science researchers at Penn State demonstrated that transcriptions of phone calls can be generated from radar measurements taken up to three meters, or about 10 feet, from a phone. While accuracy remains limited — around 60% for a vocabulary of up to 10,000 — the findings raise important questions about future privacy risks. 

With the exponential expansion of medical databases, the number of records in a single file has reached hundreds of millions, and the number of variables has increased significantly (such as the MIMIC database and the 4,484 variables in the ELSA survey). Traditional SQL queries and distributed storage systems are difficult to meet the needs of ordinary researchers due to their high technical barriers and high maintenance costs. This study proposes an innovative "slicing + dictionary" data processing strategy: by designing a multi-level slicing scheme for clinical dimensions, event dimensions, and mixed dimensions, massive datasets are decomposed into manageable subsets; at the same time, a standardized dictionary system with an encoding-description-location-attribute structure is constructed to achieve precise mapping between clinical concepts and data locations. Experimental verification shows that this method significantly reduces computational resource consumption, improves query efficiency, and supports flexible customization, enabling ordinary computing devices to load and process large-scale data on demand, which opens up new avenues for the popularization of medical big data utilization.

FastUKB is an innovative data analysis tool tailored for medical researchers, streamlining access, extraction, and analysis of UK Biobank (UKB) data—the world’s largest biomedical database with health records of over 500,000 British individuals and 10,000+ complex variables. It solves key challenges: UKB’s intricate structure, technical barriers from traditional SQL/Python extraction (difficult for non-coders), and RAP Queue Browser’s 30-variable per-operation limit. Boasting an intuitive interface, efficient batch extraction, and intelligent analysis, it lowers technical hurdles, letting clinicians/researchers easily derive insights. Deployable locally and linked to UKB-RAP, it processes diverse data, accelerating research from raw data to publication.
