Brain-Powered Wheelchair Shows Real-World Promise

“In one of the first studies of its kind, several people with motor disabilities were able to operate a wheelchair that translates their thoughts into movement. The study by researchers at The University of Texas at Austin and published today …

Break­ing ni­tro­gen while gen­er­at­ing meth­ane

“Scientists have successfully enhanced cultivation of a microorganism that can fix nitrogen (N2) while producing methane (CH4) and ammonia (NH3) and investigated exciting details of its metabolism. Carbon and nitrogen are essential elements of life. Some organisms take up key …

Build a 64kB home computer based on an Arduino Mega 256

“This is another retro compute project. Use an Arduino Mega256, 64kB serial RAM, a display and a keypad to build a standalone computer. The idea I had the idea to build a standalone computer resembling the old ZX81 computer when …

‘Butterfly Bot’ is Fastest Swimming Soft Robot Yet

“Inspired by the biomechanics of the manta ray, researchers at North Carolina State University have developed an energy-efficient soft robot that can swim more than four times faster than previous swimming soft robots. The robots are called “butterfly bots,” because …

Catching the dynamic Coronal Web

“Researchers discover an important clue as to what mechanism drives the solar wind Using observational data from the U.S. weather satellites GOES, a team of researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany …

Cosmic chocolate pralines: general neutron star structure revealed

“Through extensive model calculations, physicists at Goethe University Frankfurt have reached general conclusions about the internal structure of neutron stars, where matter reaches enormous densities: depending on their mass, the stars can have a core that is either very stiff …

DIY Sports Push Buttons - Based on ESP32-C3

“Here I made four sports push buttons with arcade buttons using DFRobot Beetle ESP32-C3. Story Push buttons, also known as tactile switches, can be found everywhere from simple lamps, and doorbells to large industrial machines. There are so many …
