Tracking atoms during fuel cell cycles: KAIST team reveals the atomic-scale secret behind fuel cell catalyst durability

The Korea Advanced Institute of Science and Technology (KAIST)
Peer-Reviewed Publication

Hydrogen fuel cell vehicles have long been hailed as the future of clean mobility: cars that emit nothing but water while delivering high efficiency and power density. Yet a stubborn obstacle remains. The heart of the fuel cell, the platinum-based catalyst, is both expensive and prone to degradation. Over time, the catalyst deteriorates during operation, forcing frequent replacements and keeping hydrogen vehicles costly.

Older patients are open to smart ring technology for home-based remote monitoring

University of Eastern Finland
Peer-Reviewed Publication

Older patients susceptible to chronic neurological conditions are willing to use wearables for remote monitoring to support their health and well-being at home. Conducted at the University of Eastern Finland, a recent study found that older patients are open to using wearable smart rings and view themselves as active contributors to their own care. The possibility for caregivers to access patient data collected was seen as reassuring and motivating, providing a sense of safety and guidance.

“Junk DNA“ supports nerve cell regeneration

Estonian Research Council
Peer-Reviewed Publication

A recent scientific study co-authored by an Estonian researcher Indrek Koppel (Tallinn University of Technology) showed how genomic DNA repeat sequences that were previously considered useless play an important role in repairing nerve damage. The discovered mechanism may contribute to future treatment strategies for brain and spinal cord injury, as well as other nervous system disorders.
