Culinary medicine education program shows positive outcomes for low-income patients with diabetes

A culinary medicine curriculum significantly improved biometric and diet-related behavioral outcomes among low-income patients with type 2 diabetes. Participants showed reduced glycosylated hemoglobin levels and increased consumption of fruits and vegetables, suggesting a positive impact on diabetes management.

Fear of predators in free-living wildlife reduces population growth over generations

A new study by University of Western Ontario researchers finds that fear of predators can reduce prey population growth rates over generations. The study, led by Professor Liana Zanette, demonstrates for the first time in any free-living wild animal that fear itself can halve populations in a short period.

Osterweil receives funding for project aimed at enabling invisible security and privacy for resilient human-centric cybersecurity systems

Eric Osterweil, George Mason University Assistant Professor, receives $40,000 funding to develop an adaptive encryption platform and threat intelligence information sharing system. The project aims to enable usable cryptographic protections for email transactions and establish a foundation for future cybersecurity efforts.

Europe’s most valuable marine species “reduced to a fraction” of their current population size by 2100

Over one quarter of Europe's 20 most highly-fished marine species will face extreme pressure by 2100 if no action is taken to address climate change, overfishing, and mercury pollution. The study projects a significant decline in population size for key species like great Atlantic scallop, red mullet, and common octopus.
