Dartmouth engineering researchers have developed a new approach for detecting a speaker’s intent to mislead. The approach’s framework, which could be developed to extract opinion from “fake news,” among other uses, was recently published as part of a paper in Journal of Experimental & Theoretical Artificial Intelligence. Although previous studies have examined deception, this is...

Robots Can Learn How to Support Teachers in Class Sessions

Robots can take just three hours to successfully learn techniques which can be used to support teachers in a classroom environment, according to new research. The study, published in Science Robotics, saw a robot being programmed to progressively learn autonomous behaviour from human demonstrations and guidance. A human teacher controlled the robot, teaching it how to...

Virtual Walking System for Re-Experiencing the Journey of Another Person

A research team led by Professor Michiteru Kitazaki from the Toyohashi University of Technology, Associate Professor Tomohiro Amemiya from the University of Tokyo, and Professor Yasushi Ikei from Tokyo Metropolitan University have developed a virtual walking system. This system records a person walking, then re-plays it to another user through the oscillating optic flow and...

Prehistoric AC: Study Suggests T. Rex Had an Air Conditioner in Its Head

Tyrannosaurus rex, one of the largest meat-eating dinosaurs on the planet, had an air conditioner in its head, suggest scientists from the University of Missouri, Ohio University and University of Florida, while challenging over a century of previous beliefs. In the past, scientists believed two large holes in the roof of a T. rex‘s skull —...

Ancient Civilizations Were Already Messing Up the Planet

As issues like climate change, global warming, and renewable energy dominate the national conversation, it’s easy to assume these topics are exclusive to the modern world. But a huge collaborative study in Science reveals that early humans across the entire globe were changing and impacting their environments as far back as 10,000 years ago. “Through this crowdsourced...
