A novel ink may allow 3D-printing bones with living cells to repair damaged bones. The ink uses a technique that prints bone-like structures in a microgel matrix that harden within minutes.

Brain hyperactivity may be a predictor of Alzheimer's disease (AD) onset, as seen with abnormal activation on functional MRI scans in brain areas related to AD in people without dementia diagnoses.  

In a highly controlled study, people who ate a low-carb, animal-based diet had lower insulin and glucose levels than those eating a low-fat, plant-based diet, despite eating 550-700 more calories.

Gene editing therapies, like CRISPR, can correct mutations related to diseases, like retinal degeneration. Gene therapy might be successful if delivered before microglia activation and photoreceptor cell death in eye.
