AI Authority Effect: Predictive Framing Makes People Forfeit Guaranteed Money

A preregistered behavioral implementation of Newcomb's paradox with 1,305 participants found that framing a predictor as AI increased the odds of forgoing the guaranteed reward by a factor of 3.39 (95% CI: 2.45–4.70) compared with random framing, reducing earnings by 10.7–42.9%. Over 40% of participants treated AI as a predictive authority, and the effect persisted even when predictions failed.

Scientists Use AI to Test Life With Only 19 Amino Acids

Columbia/MIT/Harvard team used AI protein-language models to redesign all 52 essential ribosomal proteins in E. coli without isoleucine, creating strain Ec19 that stayed above 90% wild-type fitness for 450 generations.

AI Must Unlearn Old Physics to Discover New Physics

Princeton/Flatiron study shows transfer learning cuts cosmological AI simulation costs 10x but risks negative transfer that masks genuinely new physics.

Warwick Astronomers Use New AI System to Confirm More Than 100 Exoplanets Hidden in NASA TESS Data

Astronomers at the University of Warwick have confirmed more than 100 exoplanets, including 31 newly identified worlds, using a new artificial intelligence system applied to NASA's Transiting Exoplanet Survey Satellite (TESS) data — among them rare ultra-short-period giants in the so-called “Neptunian desert,” a region where few planets are expected to exist.

Sandia Algorithm Lets Neuromorphic Hardware Solve Partial Differential Equations

Sandia computational neuroscientists Brad Theilman and Brad Aimone developed a new algorithm enabling neuromorphic hardware to tackle partial differential equations — the mathematical foundation of fluid dynamics, electromagnetic fields, and structural mechanics.

AI That 'Mumbles to Itself' Learns Smarter on Sparse Data

OIST researchers showed that pairing AI with self-directed inner speech and working memory — invisible to users — improved how their models learned, adapted to new situations, and multitasked, and let the system work with sparse data instead of the extensive data sets usually required.

DNA Robots That Hunt Viruses and Deliver Drugs Inside Your Body

Researchers are building programmable DNA nanomachines — with rigid joints and molecular logic — designed to move through the bloodstream, deliver drugs, and target cancer cells or viruses, though most remain at the proof-of-concept stage.
