Carbon rings push limits of chemical theories

mercredi 29 novembre 2023 par Przemys?aw Gawe?, Cina Foroutan-Nejad
Nature, Published online: 29 November 2023; doi:10.1038/d41586-023-03575-5Scientists are tantalized by the many forms that carbon could adopt — some of which are predicted to have extraordinary properties. The synthesis of three new all-carbon molecules is therefore a source of (...)

Remote collaboration fuses fewer breakthrough ideas

mercredi 29 novembre 2023 par Yiling Lin, Carl Benedikt Frey, Lingfei Wu
Nature, Published online: 29 November 2023; doi:10.1038/s41586-023-06767-1Analysis of research articles and patent applications shows that members of teams that collaborate remotely are less likely to make breakthrough discoveries than members of on-site (...)

The genetic diversity of Bantu-speaking populations helped to shape African history

mercredi 29 novembre 2023
Nature, Published online: 29 November 2023; doi:10.1038/d41586-023-03379-7Analysis of a massive genomic data set reveals the profound effects that the movement of Bantu-speaking peoples had on Africa’s biological, linguistic and cultural landscape. These findings provide valuable insights for a (...)

mercredi 29 novembre 2023 par Hamed Nilforoshan, Wenli Looi, Emma Pierson, Blanca Villanueva, Nic Fishman, Yiling Chen, John Sholar, Beth Redbird, David Grusky, Jure Leskovec
Nature, Published online: 29 November 2023; doi:10.1038/s41586-023-06757-3There is extreme socioeconomic segregation in large US cities, arising from a greater choice of differentiated spaces targeted to specific socioeconomic groups, which can be countered by positioning city hubs (such as (...)

mRNA reading frame maintenance during eukaryotic ribosome translocation

mercredi 29 novembre 2023 par Nemanja Milicevic, Lasse Jenner, Alexander Myasnikov, Marat Yusupov, Gulnara Yusupova
Nature, Published online: 29 November 2023; doi:10.1038/s41586-023-06780-4The accuracy of eukaryotic ribosome translocation relies on eukaryote-specific elements of the 80S ribosome, elongation factor 2 and transfer RNAs, all of which contribute to the maintenance of the messenger RNA reading (...)
