Interstellar Visitor 3I/ATLAS: Search for Technosignatures
A 2025 radio search with the Allen Telescope Array targeted 3I/ATLAS, the third confirmed interstellar object to pass through our solar system, for possible technosignatures. Although no narrowband signals were detected, the study set strong upper limits on engineered radio emissions and highlighted the scientific value of constraining what is not present.

Harvard and the Galileo Project’s Infrared Hunt for Technosignatures
An all-sky infrared camera array built for the Galileo Project is bringing rigorous science to the search for extraterrestrial technosignatures and anomalous aerial phenomena. Nicknamed “Dalek,” the system has already detected hundreds of thousands of objects, including statistical outliers that remain after machine-learning filtering of birds, satellites, and aircraft, marking a new era in UAP…

Quantum-World Energy Harvesting — A Step Toward Tomorrow’s “Impossible” Tech
Quantum energy research is exploring ways to harvest usable power from effects such as tunneling, zero-point fluctuations, and nanoscale motion. The piece emphasizes that these systems follow conservation laws while treating certain forms of randomness as usable inputs, with potential applications in sensors and autonomous systems. It also argues that such technologies can seem mysterious…

SETI@home’s Final 100 Signals: The Search That Refused to Die Quietly
SETI@home has narrowed 12 billion possible detections to 100 candidate signals for further study, potentially with China’s FAST radio telescope. The piece reflects on the milestone as both a scientific achievement and a case study in how a civilization might normalize or quietly contain evidence of non-human intelligence through caution, complexity, and process.

The “Dorito Craft” Over Area 51: A Familiar Shape in a Familiar Place
A reported triangular “Dorito-shaped” aircraft near Area 51 has revived long-running UFO speculation, but the larger point is the persistent pattern of triangle sightings over decades. From a skeptical, conspiracy-aware view, the real mystery is not whether it was aliens, but why secrecy, uncertainty, and unexplained aerial anomalies keep recurring in the same places.
