Continuous monitoring of changes in patients' blood would be a transformative advance for doctors and Stanford bioengineers brought us one step closer to that reality.
In the largest study of testosterone treatment ever carried out, scientists have found regular injections of the hormone appeared to lower the risk of developing type 2 diabetes.
In mouse studies, the team tweaked immune cells to fight off the rogue T cells that damage insulin-producing cells in the pancreas, preventing diabetes from developing.
The earring would pierce the earlobe and pulse high-frequency radio waves through the surrounding tissue as a way of measuring blood sugar levels.
A proof-of-concept study has demonstrated a novel insulin molecule that can sense blood sugar levels and self-adjust its activity in response to a patient’s needs.
Scientists have discovered a new way insulin secretion is controlled via pancreatic cells.
The efficacy of metformin, a first-line drug treatment for type 2 diabetes, may be influenced by microbial metabolites produced in the gut.
The diabetes drug exenatide is currently being investigated as a Parkinson's treatment in Phase 3 human trials.
