Macleod at the University of Toronto, isolated insulin in 1921 and used it to successfully treat a diabetic patient, 14-year-old Leonard Thompson, in January 1922 — transforming type 1 diabetes from an almost universally fatal diagnosis into a manageable condition, work that earned Banting and Macleod the 1923 Nobel Prize.

Frederick Banting and Charles Best, working under J.J.R. Macleod at the University of Toronto, isolated insulin in 1921 and used it to successfully treat a diabetic patient, 14-year-old Leonard Thompson, in January 1922 — transforming type 1 diabetes from an almost universally fatal diagnosis into a manageable condition, work that earned Banting and Macleod the 1923 Nobel Prize.
The year insulin was isolated and first successfully used to treat a person with diabetes.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.

Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
