Bioluminescence, the ability of organisms to emit light, originated in marine invertebrates known as octocorals at least 540 million years ago, a study by Smithsonian scientists indicates. This discovery extends the known timeline of bioluminescence's development in animals by about 300 million years. Published in the Proceedings of the Royal Society B on April 23, the study provides new i

Researchers at the University of Copenhagen have developed a method that could enhance the precision of measuring time by leveraging the properties of superradiant atoms. This approach aims to address some of the existing limitations of modern atomic clocks, which are crucial in technologies ranging from GPS systems to space travel. The second, as a unit of measurement, is defined with gre

The issue of class imbalance has been well-studied in the multi-class classification framework, but its exploration within multi-dimensional classification (MDC) has been somewhat overlooked due to the complexity of the imbalance shift phenomenon. This occurs when a sample is categorized as belonging to both a minor and a major class, depending on the labeling dimension. Addressing this ga

Over the past ninety years, humanity has explored various fusion technologies, yet only a select few have managed to generate a thermal fusion plasma with electron temperatures surpassing 10M C. Zap Energy's innovative approach, known as a sheared-flow-stabilized Z pinch, has now successfully exceeded this plasma temperature milestone in a remarkably compact device.
