"Life, as we know it, has been evolving for billions of years. It has evolved to process information and materials by zillions of nano-scale molecular “machines” all working in parallel, competing as well as backing each other up, maintaining themselves and the ecosystem supporting them. The total complexity of this machinery, also called the biosphere, is mindboggling. In DNA, one bit of information takes less than 50 atoms. Given the atomic nature of physical matter, every part in life’s machinery is as miniature as possible in principle. Can AI achieve such a complexity, robustness, and adaptability by alternative means and without DNA?" https://blog.oup.com/2024/04/is-humanity-a-passing-phase-in-evolution-of-intelligence-and-civilisation/ #Maths #Math #Mathematics #Science #Medicine #Technology #STEM #AI #ArtificialIntelligence @science

"For some people, their status was elevated still further by the widely publicized discovery in 2007 that some Neanderthals carried genes suggesting they had red hair and light skin. These ancient inhabitants of Europe and Asia became coded as white, and on social media some people began to claim Neanderthal ancestry as a mark of racial superiority." http://www.doi.org/10.1126/science.z6n7io6 #DOI #Science #STEM #Anthropology #Neanderthals #Racism #Racist @science @anthropology

"Our results show that presenting the success rate of previous raters works as an incentive to evaluate information more accurately, but that monetary bonuses provide the strongest increase in accuracy, and that only remuneration is associated with a greater use of external resources (e.g., search engines) that have been shown to meaningfully improve evaluation of new content."
