Methylene blue and light inactivates SARS-CoV-2 on N95 respirators and masks, study finds

Researchers at the University of Washington show that methylene blue (MB) and light can decontaminate masks and respirators by inactivating three tested coronaviruses without compromising integrity. The method is effective, low-cost, and does not require specialized equipment, making it applicable in any setting.

Reductive stress promotes protein aggregation in neuroblastoma cells, impairs neurogenesis

Cells require a balance among oxidation-reduction reactions, or redox homeostasis. Loss of that balance to create oxidative stress is often associated with neurodegeneration. Less is known about how loss of that balance at the other end of the spectrum -- reductive stress, or RS -- may affect neurons.
