On 15 September 2022, Science published the Research Article “Structural basis for strychnine activation of human bitter taste receptor TAS2R46” by W. Xu et al. (1). On 22 November 2022, an Editorial Expression of Concern alerted readers to concerns regarding fig. S10D (1). The authors have now corrected the paper, and the Editorial Expression of Concern has been replaced by an Erratum (3). As described in the Erratum, the authors repeated bioluminescence energy transfer experiments that were the basis for figs. S9, C to F, and S10D. The new data did not provide strong functional support for the structure-based suggestion of precoupling between TAS2R46 and the G protein gustducin. In the corrected version of the Research Article, Xiaoling Cao is no longer an author; figs. S9, C to F, and S...

Optical fibre connected to a dilution refrigeratorHarsh Rathee/Department of Physics Photographs accompanying most scientific papers might politely be called “functional”. But this collection of images from Imperial College London’s research photography competition proves that research can be beautiful. The top image, by Harsh Rathee of the physics department, shows an optical fibre connected to a dilution refrigerator, a device that creates a temperature a thousandth that of the vacuum of space. By observing how light interacts with sound waves at this incredibly low temperature, researchers can explore the unique properties of matter at the quantum level.
