Rather a lot of speculation about the supposed discovery of phosphine in the atmosphere of Venus and how it came to get there ...

My leanings are toward chemistry not biology. We still don't understand the geology of Venus well enough know if there might be a mechanism to produce it. I would not be surprised if it gets found on Io eventually. It has been found on Jupiter and Saturn decades ago.

Cause of Alzheimer's disease traced to mutation in common enzyme
Quote:
Researchers from Tokyo Metropolitan University have discovered a new mechanism by which clumps of tau protein are created in the brain, killing brain cells and causing Alzheimer's disease. A specific mutation to an enzyme called MARK4 changed the properties of tau, usually an important part of the skeletal structure of cells, making it more likely to aggregate, and more insoluble. Getting to grips with mechanisms like this may lead to breakthrough treatments.
