We Grew Algae and Asked Spectrum Editors to Taste It
Algae could be the environmentally-friendly superfood we’ve all been waiting for. But will anyone actually eat it? When was the last time you sipped algae? Chances are, you’ve never done that. But while working on a special report about potential climate-saving technologies, IEEE Spectrum decided to try to grow Spirulina, which proponents have pitched as… Continue reading We Grew Algae and Asked Spectrum Editors to Taste It
New Optimization Algorithm Exponentially Speeds Computation
Image: iStockphoto A new algorithm could dramatically slash the time it can take computers to recommend movies or route taxis. The new algorithm, developed by Harvard University researchers, solves optimization problems exponentially faster than previous algorithms by cutting the number of steps required. Surprisingly, this approach works “without sacrificing the quality of the resulting solution,” says… Continue reading New Optimization Algorithm Exponentially Speeds Computation
Device Uses Flashes of Light to Restore Hearing
Image: University Medical Center Göttingen Scientists in Germany have succeeded in restoring hearing sensations in gerbils using flashes of light. The technique, if it can be developed for humans, could offer a more refined, high-resolution auditory experience than what can be achieved with current hearing devices such as the cochlear implant. The scientists, led by Tobias Moser, a professor of… Continue reading Device Uses Flashes of Light to Restore Hearing
Nanotechnology Takes Giant Leap Foward by Manipulating Molecules
Image: Forschungszentrum Jülich/T. EsatThis illustration shows a PTCDA molecule positioned upright on a silver platter [left]. Normally, the molecule would lie flat atop a layer of silver atoms [right]. If nanotechnology has captured the popular imagination in any way, it has likely been in the form of so-called molecular nanotechnology, in which nanoscale machines assemble… Continue reading Nanotechnology Takes Giant Leap Foward by Manipulating Molecules
The IceCube Neutrino Detector at the South Pole Hits Paydirt
Photo-illustration: IceCube Collaboration/NSF After 3.9 billion years of hurtling unhindered through the vast reaches of the universe, a ghostly neutrino particle died on 22 September 2017. It was annihilated when it collided with an atom in the frozen darkness two kilometers beneath the surface of the south polar ice cap. But this subatomic particle’s death… Continue reading The IceCube Neutrino Detector at the South Pole Hits Paydirt
Social Home Robots: 35 Years of Progress

This is the 8th year of the festival, and after bouncing around between San Francisco, Pittsburgh, and Los Angeles, the festival has (at least temporarily) settled on the greatest… Continue reading Social Home Robots: 35 Years of Progress
Facebook’s DensePose Tech Raises Concerns About Potential Misuse
Image: Facebook In early 2018, Facebook’s AI researchers unveiled a deep learning system that can transform 2D photo and video images of people into 3D mesh models of those human bodies in motion. Last month, Facebook publicly shared the code for its “DensePose” technology, which could be used by Hollywood filmmakers and augmented reality game… Continue reading Facebook’s DensePose Tech Raises Concerns About Potential Misuse
Popcorn-Driven Robotic Actuators
Photo: Cornell University It’s not that often I can steal the title of a paper and use it for a blog article that people will actually read, but I think “Popcorn-Driven Robotic Actuators” totally works, so credit for that to Steven Ceron at Cornell University, who’s the first author on this paper, presented at the IEEE International… Continue reading Popcorn-Driven Robotic Actuators
Low-Cost SBCs are Ideal for Industrial and Medical Applications
Industrial embedded computer system maker WinSystems has introduced a new series of single board computers (SBCs) in a NANO-ITX form factor. While measuring just 4.27 inches (120 mm) square, these ITX-N-3800 industrial SBCs offer robust I/O and expansion options, an extended operating temperature range, and abundant functionality for IIoT applications. The series is ideal for… Continue reading Low-Cost SBCs are Ideal for Industrial and Medical Applications
