US Navy Research Lab engineers 3D print functional lightweight cylindrical antenna arrays

Posted by in categories: 3D printing, military

Engineers at the US Navy Research Laboratory (NRL) have deployed a 3D printer to fabricate optimized antenna components that could be key to advancing the US Navy’s radar monitoring capabilities.

Utilizing 3D printing, the engineers were able to create cylindrical arrays at a lower cost and with reduced lead times compared to those incurred using conventional specialized equipment. The resulting parts also proved to be significantly lighter than previous iterations, potentially lending them new end-use navigational or defense applications.

“3D printing is a way to produce rapid prototypes and get through multiple design iterations very quickly, with minimal cost,” said NRL electrical engineer Anna Stumme. “The light weight of the printed parts also allows us to take technology to new applications, where the heavy weight of solid metal parts used to restrict us.”

New machine learning theory raises questions about nature of science

Posted by in categories: information science, robotics/AI, science, space

A novel computer algorithm, or set of rules, that accurately predicts the orbits of planets in the solar system could be adapted to better predict and control the behavior of the plasma that fuels fusion facilities designed to harvest on Earth the fusion energy that powers the sun and stars.

Electron refrigerator: Ultrafast cooling mechanism discovered in novel plasma

Posted by in category: innovation

Researchers from the Cluster of Excellence “CUI: Advanced Imaging of Matter” have achieved a breakthrough—creating a completely new type of plasma by combining state-of-the-art technologies using ultrashort laser pulses and ultracold atomic gases. They report on a novel electron cooling mechanism occurring in such plasmas in the journal Nature Communications.

WHO: COVID-19 didn’t leak from a lab. Also WHO: Maybe it did

Posted by in category: biotech/medical

A World Health Organization mission to China to investigate the origins of COVID-19 reported earlier this week that it had ruled out the idea that the coronavirus pandemic could have sprung from a lab leak, but taken as a whole, the lab-leak theory remains a serious possibility; the World Health Organization’s investigative team will need to present any new evidence it used to rule out the theory when it releases its mission report.

Forget 5G, the U.S. and China Are Already Fighting for 6G Dominance

Posted by in categories: holograms, internet, neuroscience

For companies and governments, the stakes couldn’t be higher. The first to develop and patent 6G will be the biggest winners in what some call the next industrial revolution. Though still at least a decade away from becoming reality, 6G — which could be up to 100 times faster than the peak speed of 5G — could deliver the kind of technology that’s long been the stuff of science fiction, from real-time holograms to flying taxis and internet-connected human bodies and brains.


Most of the world is yet to experience the benefits of a 5G network, but the geopolitical race for the next big thing in telecommunications technology is already heating up. For companies and governments, the stakes couldn’t be higher.
