Researchers from The University of Osaka have demonstrated that a wireless electroencephalogram transmission system can operate using energy harvested from the temperature difference between the human body and the ambient air. The low-power device successfully operated outdoors at high temperatures, demonstrating stable performance without external power or airflow. This technology could enable the development of maintenance-free sensing systems for health monitoring and infrastructure applications in the future.
A leading expert in antibody-drug-conjugate (ADC) technology, Binghamton University Professor of Pharmaceutical Sciences L. Nathan Tumey has worked for nearly two decades developing new approaches for the treatment of cancer. Now, thanks to a substantial $2.75M grant from the National Institutes of Health, Tumey is taking an exciting step forward in his research — leading the charge to transition this exciting technology platform for applications outside of oncology.
Scientists built a new theoretical model that learns from interactions. Positive interactions strengthened connections, and negative interactions weakened connections. Model revealed that strong connections can lead to feedback loops and echo chambers. Findings extend to diverse spreading systems, from social ideas to infections to animal behavior to neural signals.
