insulin

Scientists are developing needle-free ways to deliver medicine, including insulin, with the goal of replacing traditional injections for millions of patients, particularly people with diabetes. The work, highlighted by National Geographic, covers new technologies that could deliver drugs through the skin or other routes without needles. If successful, the approach could reduce pain and needle anxiety for patients who need daily injections.

New reporting from Wired describes research suggesting certain pancreatic cells can be converted into insulin-producing beta cells with a single genetic modification, raising hopes for a regenerative approach to treating diabetes. The finding is drawing attention as diabetes affects hundreds of millions of people worldwide and current treatments require ongoing insulin management rather than restoring the body's own insulin production.
