insulin

National Geographic reports on scientific efforts to replace insulin injections with needle-free alternatives, a change that could affect millions of people with diabetes who rely on daily injections. Researchers are exploring new delivery methods that would remove the need for needles in administering insulin and potentially other medicines.

A Wired report describes new research suggesting certain pancreatic cells can be converted into insulin-producing beta cells with a single genetic modification, offering a potential new avenue for treating diabetes. Scientists say the finding could eventually help restore insulin production in patients, though it remains at an early stage.
