Image: University of Hong Kong/Science RoboticsMicrorobots designed to carry stem cells (fluorescent green) throughout the body are shown here on a cell culture plate. The astonishing thing about stem cells is that they can be coaxed, in the laboratory, into becoming nearly any kind of cell—from bone marrow to heart muscle. That remarkable capability has for… Continue reading Microbots Deliver Stem Cells in the Body

Synthetic Biology Behemoth Aims to Police Its Own Industry
Photo: Ginkgo Bioworks Try as a nefarious actor might, it would be near impossible to order the ingredients for making a deadly virus such as smallpox from scratch—at least not from any reputable company. That’s because the world’s leading gene-synthesis firms all routinely screen customer requests against DNA sequences from hazardous viruses, bacteria, toxins and… Continue reading Synthetic Biology Behemoth Aims to Police Its Own Industry
Jolt the Brain, Then Listen Closely
Photo: Dawn Harmer/SLAC National Accelerator Laboratory If an electric current passes through the brain, does anyone hear it? Earlier this year, researchers in the United Kingdom showed that stimulating the brain with mild direct currents helped people stop stuttering. Neurostimulation has also shown promise for treating conditions such as migraines, depression, and the physical effects of… Continue reading Jolt the Brain, Then Listen Closely
Experts Disagree on Top Applications for 5G
In the world of emerging technologies, you often see industry and academic experts take on the roles of “good cop” or “bad cop.” Whether someone plays a particular role depends largely on their own interests. When it comes to the rollout of 5G networks, carriers and equipment suppliers are all in. On the other hand,… Continue reading Experts Disagree on Top Applications for 5G
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

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
