Swedish researchers from Linköping University and the KTH Royal Institute of Technology have developed the world’s first wooden transistor. Although wood is not semiconductive, the researchers stripped hardwood balsa of its tough lignin and then filled the remaining material with a mixed electron-ion conducting polymer called PEDOT:PSS. By stacking millimeter-thick units that operated as electrodes

Acquiring human tissue samples for biological research can be a challenging process. Obtaining tissue samples through ethical methods, such as organ donation and surgical procedures, can still be a difficult and limited process. Additionally, the specific size and type of tissue samples needed for research projects can be restricted. This has led scientists to look
SpaceX’s 40-story Starship mega-rocket, the most powerful ever launched, took off towards space for the first time on April 20. However, the rocket’s Super Heavy booster fired more than two dozen truck-sized Raptor engines at once, causing debris to fly and soil and sand to rain down on a town five miles away. The launchpad
