Two new studies offer insight into the factors that coincide with adolescent inhalant use in the U.S., a dangerous pastime that can have lifelong — or life-ending — consequences.

An international research team led by anthropologist and population geneticist Professor Dr. Joachim Burger from the Institute of Organismic and Molecular Evolution at Johannes Gutenberg University Mainz has now analysed genomes of individuals from the former Roman frontier zone between 400 and 700 AD in southern Germany. Their results provide unexpectedly detailed insights into a period of major transformation. The findings have been published in the journal Nature.

In cases involving serious criminal offenses, the police are permitted to conduct acoustic surveillance of telephones, private premises, or vehicles to record conversations of suspected offenders or to analyze chat communications. When criminal groups communicate in languages other than German, language mediators or so-called intercept interpreters-translators (IITs) are tasked with rendering the content into German. Their role extends beyond mere linguistic transfer to include the communication of additional information relevant to the investigation. The results of their work also serve as evidence in court proceedings. To ensure effective crime prevention and prosecution, the police, the prosecuting attorneys, and courts depend on precise intercept interpreting and translation. This is the very topic of the new research project on "Qualified language mediation for efficient forensic communication surveillance", QSEK for short, funded by the German Federal Ministry of Research, Technology, and Space with around EUR 880,000 through its Validation of the Technological and Social Innovation Potential of Scientific Research (VIP+) program.

Zoonotic diseases continue to present health, social, and economic challenges in China. While the country has demonstrated strong outbreak response capabilities, current efforts remain reactive and top-down. Shifting toward primary prevention at the human–animal–environment interface with enhanced risk communication offers a more sustainable approach to reducing zoonotic disease risks. This review synthesized peer-reviewed and gray literature in English and Chinese to characterize human–animal contact behaviors associated with 93 zoonotic diseases monitored by China’s public health, agricultural, and forestry sectors. It examined contact pathways across key animal groups known to carry zoonotic pathogens, identified human populations at risk, and analyzed the demographic, socio-cultural, and ecological factors shaping these contacts. Focusing on four major human–animal interfaces, the review further identified lessons and best practices for effective risk communications. Findings reveal that human–animal contact in China is diverse and embedded in daily routines, cultural practices, and economic activities, with distinct risk profiles presented across animal groups and socio-ecological settings. Populations such as smallholder farmers, herders, rural residents, market vendors, and workers in informal sectors face higher exposure risk, influenced by socio-economic conditions and ecological changes. Gaps remain in surveillance of informal practices, emerging pathogens, and behavioral data. Evidence from global and local experiences highlights the value of behavior-centered, community-engaged communication grounded in One Health principles, emphasizing participatory design, culturally relevant education, local leadership, and integration with public service systems. Overall, this review provides an integrated understanding of zoonotic disease risks and prevention opportunities from social-behavioral and communication perspectives. It identified priority populations, settings, and best practices for targeted and effective strategies, underscoring the need for coordinated One Health efforts to address complex human–animal–environment interactions and promote proactive zoonotic disease prevention in China and beyond.

New Australian research has found that popular fitness and supplement videos on TikTok can leave young men feeling worse about their fitness and nutrition, and increase their interest in using muscle‑building supplements. The Flinders University study, published in the international journal Body Image, is one of the first to experimentally test the immediate impact of TikTok content on young men’s body satisfaction and health intentions
