New research by University of Texas at Dallas geoscientist Dr. Robert Stern and a colleague suggests a geological explanation for why conclusive evidence for advanced extraterrestrial (ET) civilizations has not […]
Geoconservation is an increasingly widely adopted theoretical, practical and administrative approach to the protection of geological and geomorphological features of special scientific, functional, historic, cultural, aesthetic, or ecological value.
Sperm whales (Physeter macrocephalus) are highly social mammals that communicate using sequences of clicks called codas. While a subset of codas have been shown to encode information about caller identity, […]

Editor’s note: In case you have not spent time going through the torrent of images from the two NASA Astrobiology Mars Rovers currently in operation, there’s one feature on Mars […]
This study examines the hypothesis that the rapid development of Artificial Intelligence (AI), culminating in the emergence of Artificial Superintelligence (ASI), could act as a “Great Filter” that is responsible […]
Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture.
I have been living with the image in my mind of the Pioneer plaques and Voyager Golden Records heading across the outer solar system and into interstellar space for half […]
Following in NASA’s storied tradition of sending inspirational messages into space, the agency has special plans for Europa Clipper, which later this year will launch toward Jupiter’s moon Europa. The […]
An astronomy lesson on binary stars could begin with a series of complex diagrams and data, or with a clip from the movie Star Wars where Luke Skywalker looks up […]
In a rapidly changing academic-scientific context, it is essential to adapt new learning strategies that foster the acquisition of new knowledge and the development of skills in future professionals, such […]
