Teasing out biochemical information from ancient organic-rich sediments, notably the timing of the emergence of photosynthesis relative to the inferred oxygenation of Earth’s atmosphere, remains a ...

We explore the key differences between the main social media platforms and how they are likely to influence information spreading and the formation of echo chambers. To assess the different dynamics, ...

Among them, Dux has been considered as a master inducer for regulating ZGA process (3 – 5). Dux (also named as Duxf3) in mice and its human homolog DUX4 are double homeodomain genes activated during ...

Our study presents a flash Joule heating (FJH) combined with chlorination (FJH-Cl 2) as an efficient method for rare earth elements (REE) separation and recovery from electronic waste. FJH-Cl 2 ...

Surveys are a primary source of data across the sciences, from medicine to economics. I demonstrate that the assumption that logically coherent responses are from humans is now untenable. I show that ...
