New software algorithms reduce the time and material needed to produce objects with 3-D printers. Here, the wheel on the left was produced with conventional software and the one on the right with the new algorithms. (Purdue University photo/Bedrich Benes ...

A computer science professor reveals how to print a 3-D Christmas tree efficiently and with zero material waste, using the world's first algorithm for automatically decomposing a 3-D object into what are called pyramidal parts. Just in time for Christmas ...

Over lunch at last Wednesday’s Regional Energy Innovation Summit, attendees were treated to a presentation from Ted Zoller, Ph.D., executive director of University of North Carolina at Chapel Hill’s Center for Entrepreneurial Studies. Zoller, who’s ...

Machine learning has returned with a vengeance. I still remember the dark days of the late '80s and '90s, when it was pretty clear that the current generation of machine-learning algorithms didn't seem to actually learn much of anything. Then big data ...

It is now possible to take a talking-head style video, and add, delete or edit the speaker's words as simply as you'd edit text in a word processor. A new deepfake algorithm can process the audio and video into a new file in which the speaker says more or ...
