Detecting cognitive changes early in the onset of dementia would be a game-changer for thousands impacted by the disease and would allow for interventions well before significant brain changes occur. While cognitive function is often measured using paper and pencil tests with scores calculated by the number of correct answers, this number (score) omits a lot of information about the process a person uses to answer a question that might reveal important information about their brain function.

Insufficient oxygen to an area like the heart or legs, called hypoxia, is a cue to our bodies to make more blood vessels, and scientists have found some unusual partners are key to making that happen. They've found that two receptors on the surface of those cells come together then dive inside to enable the new growth, called angiogenesis, scientists report.

Researchers have shown that a protein called MondoA can activate the important health-linked process of autophagy, whereby cells are broken down and their components are recycled. MondoA both inhibited a protein called Rubicon and regulated the Prdx3 protein, which maintains the stability of energy-producing mitochondria within cells. Activation of MondoA protected against aging and age-associated kidney injury, indicating its potential as a target for the treatment of aging and age-related diseases.
