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

Chip Hall of Fame: RCA CDP 1802
Photo: Paul Rautakorpi/Wikipedia CDP 1802 Manufacturer: RCA Category: Processors Year: 1976 If the RCA Corp. had made different decisions in the 1970s, the name Joe Weisbecker could be as revered as Steve Wozniak’s is today. Weisbecker was the architect of the RCA CDP 1802 microprocessor, also known as the Cosmac. Part of what made the 1802 special… Continue reading Chip Hall of Fame: RCA CDP 1802
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
Asimo Still Improving Its Hopping and Jogging Skills
Image: Honda Research We learned last week that Honda is putting Asimo out to pasture, so to speak, which is a little sad, but not too sad: Honda is doing this because they want to instead focus on the other, more useful humanoid robots that they’ve been working on recently, like E2-DR. Honda learned a… Continue reading Asimo Still Improving Its Hopping and Jogging Skills
Don Eyles: Space Hacker
This programmer saved the Apollo 14 mission with 61 keystrokes In the early hours of 5 February 1971, Don Eyles had a big problem. Apollo 14 astronauts Alan Shepard and Edgar Mitchell orbiting the Moon, preparing to land. But it looked like they were going to have to come home without putting so much as footprint… Continue reading Don Eyles: Space Hacker
Australia’s Digital Transformation Stumbles Badly
Photo: iStockphoto An Australian Senate committee published a 146-page report assessing the government’s progress toward its goal of becoming “one of the top three digital governments in the world…that other nations can look to for guidance and inspiration,” by 2025. Given what is in the report, other nations may want to look elsewhere for their… Continue reading Australia’s Digital Transformation Stumbles Badly
Chip Hall of Fame: Intel 4004 Microprocessor
Photo: Intel Intel 4004 Manufacturer: Intel Category: Processors Year: 1971 The Intel 4004 was the world’s first microprocessor—a complete general-purpose CPU on a single chip. Released in March 1971, and using cutting-edge silicon-gate technology, the 4004 marked the beginning of Intel’s rise to global dominance in the processor industry. So you might imagine that the full… Continue reading Chip Hall of Fame: Intel 4004 Microprocessor
Forget Jet Packs—Why Don’t We Have Stair-Climbing Wheelchairs?
Photo: MIT Museum Ernesto Blanco invented his stair-climbing wheelchair in 1962 and entered it in a design challenge from the National Inventors Council, a U.S. agency that sought out technologies of potential military use. Blanco even created a one-quarter scale model [above] to show that the design actually worked. Stairs are of course tricky to… Continue reading Forget Jet Packs—Why Don’t We Have Stair-Climbing Wheelchairs?
Sprawling Wheel Leg Robot Crawls and Climbs
Photo: Ben-Gurion University of the Negev We’re always impressed by the way David Zarrouk (a professor at Ben-Gurion University of the Negev by way of UC Berkeley’s Biomimetic Millisystems Lab) manages to extract a ton of functionality from the absolute minimum of hardware in his robots. In the past, we’ve seen clever designs like a… Continue reading Sprawling Wheel Leg Robot Crawls and Climbs
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
