The Download: the Pentagon’s AI-powered lie detector and young organ limits
· Source: MIT Technology Review
The U.S. Department of Defense has requested $30.3 million over the next five years to develop “Polygraph +,” an upgraded polygraph that will integrate artificial‑intelligence and machine‑learning algorithms. The effort will also investigate “remote detection,” a technique that captures physiological signals without attaching sensors to the skin. The goal is to enhance the precision and dependability of lie‑detection tests, although experts caution that combining AI with conventional methods may introduce more uncertainty than clarity, recalling the many failed attempts to create a fool‑proof lie detector.
Simultaneously, new research on heart transplants shows that organs from young animals do not deliver the anticipated rejuvenation benefits. While the notion of extending life through tissue replacement has been floated by political leaders, recent evidence indicates that young hearts neither improve function nor slow aging in older recipients, limiting the feasibility of that approach for achieving “immortality.”
These developments matter because, on one hand, an AI‑based polygraph could influence judicial proceedings and national security protocols, while on the other, findings on the limits of regeneration with youthful organs recalibrate expectations in biotechnology and long‑term health policy.
