  摘要：Late-onset Alzheimer's disease (LOAD) is the most common form of Alzheimer's disease (AD). However, modeling sporadic LOAD that endogenously captures hallmark neuronal pathologies such as amyloid-beta (A beta) deposition, tau tangles, and neuronal loss remains an unmet need. We demonstrate that neurons generated by microRNA (miRNA)-based direct reprogramming of fibroblasts from individuals affected by autosomal dominant AD (ADAD) and LOAD in a three-dimensional environment effectively recapitu...

  摘要：The skeletons of deceased humans as well as their substrates, such as preserved dental plaque (dental calculus), and biomolecules, such as DNA, represent an archive of many otherwise invisible aspects of the past. In particular, molecular studies of skeletal individuals capture interactions between human hosts, environments, animals, plants, and pathogens (HEAPP) ( 1 , 2 ). When the tools of paleogenomics, such as ancient DNA (aDNA) analyses, are combined with broad collaborations and perspect...
• PhAI: A deep-learning approach to solve the crystallographic phase problem AI翻译

  摘要：X-ray crystallography provides a distinctive view on the three-dimensional structure of crystals. To reconstruct the electron density map, the complex structure factors F = |F|exp(i phi) of a sufficiently large number of diffracted reflections must be known. In a conventional experiment, only the amplitudes F are obtained, and the phases phi are lost. This is the crystallographic phase problem. In this work, we show that a neural network, trained on millions of artificial structure data, can s...
