After an arduous search spanning three decades, mathematicians have made a groundbreaking discovery with the aid of a supercomputer – they have finally identified a new Dedekind number. This remarkable finding marks the emergence of only the ninth Dedekind number, known as D(9), which can be expressed as 286 386 577 668 298 411 128

The poultry industry is responsible for supplying about 286 eggs per person in the US, but there is a harsh reality to this industry. Billions of male chicks are culled each year by being crushed alive or gassed at hen hatcheries worldwide. This is because chicks from egg-laying hens are not used for meat production,
Artificial Intelligence (AI) has been making progress over the years, and now, it is possible for a computer to learn from the past and predict future events. However, a new approach to AI is emerging that looks to use a different kind of computer – one that is more like a tank of water. This
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
Scientists at the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have achieved a new record level of efficiency for solar cells. The team combined two different materials, crystalline silicon and perovskite, to create a tandem solar cell that reached an efficiency level of 33.2 percent. This is an improvement from the
Recent advancements in generative AI models such as ChatGPT and DALL-E have made it feasible to produce vast amounts of human-like, high-quality creative content from a simple set of prompts. However, despite being highly capable, AI systems are not structured like human brains and do not learn in the same way. They are also not
Researchers are making strides in the development of medical devices that can be safely used inside the human body. However, powering these tiny devices remains a challenge. To address this issue, scientists have created a new type of rechargeable battery made from fully edible substances. Features and Potential Uses of the Edible Battery The prototype
A team of chemical engineers in Korea has developed a new system that could help tackle two global problems: plastic waste and rising levels of carbon dioxide. The system uses a bacterium called Cupriavidus necator to transform carbon dioxide from the air into a bioplastic. While plastic-munching bacteria have gained attention for breaking down plastic
