摘要:Ab initio calculations have an essential role in our fundamental understanding of quantum many-body systems across many subfields, from strongly correlated fermions(1-3) to quantum chemistry(4-6) and from atomic and molecular systems(7-9) to nuclear physics(10-14). One of the primary challenges is to perform accurate calculations for systems where the interactions may be complicated and difficult for the chosen computational method to handle. Here we address the problem by introducing an appro...

摘要:Large-scale outflows driven by supermassive black holes are thought to have a fundamental role in suppressing star formation in massive galaxies. However, direct observational evidence for this hypothesis is still lacking, particularly in the young universe where star-formation quenching is remarkably rapid(1-3), thus requiring effective removal of gas(4) as opposed to slow gas heating(5,6). Although outflows of ionized gas are frequently detected in massive distant galaxies(7), the amount of ...

摘要:The social media platforms of the twenty-first century have an enormous role in regulating speech in the USA and worldwide1. However, there has been little research on platform-wide interventions on speech2,3. Here we evaluate the effect of the decision by Twitter to suddenly deplatform 70,000 misinformation traffickers in response to the violence at the US Capitol on 6 January 2021 (a series of events commonly known as and referred to here as 'January 6th'). Using a panel of more than 500,000...

摘要:The parasite Cryptosporidium is a leading agent of diarrhoeal disease in young children, and a cause and consequence of chronic malnutrition(1,2). There are no vaccines and only limited treatment options(3). The parasite infects enterocytes, in which it engages in asexual and sexual replication(4), both of which are essential to continued infection and transmission. However, their molecular mechanisms remain largely unclear(5). Here we use single-cell RNA sequencing to reveal the gene expressi...

摘要:The controversy over online misinformation and social media has opened a gap between public discourse and scientific research. Public intellectuals and journalists frequently make sweeping claims about the effects of exposure to false content online that are inconsistent with much of the current empirical evidence. Here we identify three common misperceptions: that average exposure to problematic content is high, that algorithms are largely responsible for this exposure and that social media i...

摘要:Automated approaches to translation could provide a lifeline to under-resourced languages, but only if companies engage with the people who speak them.
