摘要：Cells grown on a 3D scaffold have generated a 'mini-colon' that mimics key features of the organ. Controlled expression of cancer-associated genes in the system offers a way to examine tumour formation over space and time.

摘要：Bacteria have adapted to phage predation by evolving a vast assortment of defence systems(1). Although anti-phage immunity genes can be identified using bioinformatic tools, the discovery of novel systems is restricted to the available prokaryotic sequence data(2). Here, to overcome this limitation, we infected Escherichia coli carrying a soil metagenomic DNA library(3) with the lytic coliphage T4 to isolate clones carrying protective genes. Following this approach, we identified Brig1, a DNA ...

摘要：Some fox species leap up and pounce head first into snow to capture prey that they hear below the surface. An analysis of the forces involved reveals how the shape of the skull has evolved to minimize damage from this behaviour.

摘要：The human calcium-sensing receptor (CaSR) detects fluctuations in the extracellular Ca2+ concentration and maintains Ca2+ homeostasis(1,2). It also mediates diverse cellular processes not associated with Ca2+ balance(3-5). The functional pleiotropy of CaSR arises in part from its ability to signal through several G-protein subtypes(6). We determined structures of CaSR in complex with G proteins from three different subfamilies: G(q), G(i) and G(s). We found that the homodimeric CaSR of each co...

摘要：Quantum interference can deeply alter the nature of many-body phases of matter1. In the case of the Hubbard model, Nagaoka proved that introducing a single itinerant charge can transform a paramagnetic insulator into a ferromagnet through path interference2-4. However, a microscopic observation of this kinetic magnetism induced by individually imaged dopants has been so far elusive. Here we demonstrate the emergence of Nagaoka polarons in a Hubbard system realized with strongly interacting fer...
