Researchers capture first laser-driven, high-resolution CT scans of dense objects 

Colorado State University
Peer-Reviewed Publication

A research team led by Colorado State University has achieved a new milestone in 3D X-ray imaging technology.  The scientists are the first to capture high-resolution CT scans of the interior of a large, dense object – a gas turbine blade – using a compact, laser-driven X-ray source. The work is part of a larger vision to leverage high-intensity lasers for a wide range of uses, from studying inertial fusion energy to generating bright beams of GeV electrons and MeV x-rays.

Groundbreaking study finds AI-driven interviews with children may boost accuracy in witness accounts

Abo Akademi University
Peer-Reviewed Publication

In a first-of-its-kind study published in the journal PLOS ONE, an international team of researchers led by scholars from New York University Shanghai and Åbo Akademi University in Turku, Finland explored the potential of artificial intelligence to assist in sensitive child investigative interviews. The study compared how effectively a Large Language Model (LLM), specifically ChatGPT, and untrained human interviewers were able to interview children about a mock event they witnessed. The findings suggest that AI-powered interviews may complement human efforts by improving the questioning style and efficiency of child interviews

New framework to measure economic well-being considers new and free goods and services; addition of digital goods boosts growth

Carnegie Mellon University
Peer-Reviewed Publication

In a new study, researchers developed a framework to measure the welfare contributions of new and free goods and services and quantify their benefits. By applying the framework to several examples (e.g., Facebook, Smartphone cameras), the study found that these goods and services significantly increase welfare.
