The discovery of seismic signals known as PKP precursors has puzzled scientists for decades. These signals bounce off regions in Earth’s lower mantle and return to the surface as PKP waves, traveling at varying speeds. The source of these precursor signals, which arrive before the main seismic waves passing through Earth’s core, has long been

The field of material synthesis is undergoing a remarkable transformation thanks to the groundbreaking work of James Tour’s lab at Rice University. Their innovative method, known as flash-within-flash Joule heating (FWF), is set to revolutionize the way high-quality solid-state materials are synthesized. The recent publication of their findings in Nature Chemistry on Aug. 8 heralds
Cognitive flexibility is a trait that allows individuals to quickly shift between different thoughts and concepts. This ability is crucial for multitasking, learning new skills, and adapting to new situations. While humans possess this trait, artificial intelligence (AI) systems are still lacking in this area. The gap between human cognitive flexibility and AI capabilities has
Polyurethane (PUR) foam is a widely used material in various products like mattresses, insulation, shoes, cars, airplanes, and more. However, the disposal of PUR foam poses a significant environmental challenge as most of it ends up in landfills or being incinerated. This is troubling because the main components of PUR foam are derived from fossil
